At the annual Saint Joseph Academy's Women’s Leadership Symposium, three accomplished Parker professionals shared their experiences and advice on potential career paths with the students. In support of the only all girls school in the Cleveland, Ohio area, this annual gathering connects students and successful women from the community to inspire the students by presenting a variety of different career options.
Beatriz Ibarra, Stella Beech, and Lori Martinelli spent the day speaking and networking with the students as representatives of Parker’s women’s business resource group, Peer W.
At each annual symposium, career discussions are offered as breakout sessions to facilitate a two-way conversation as guest speakers share their perspectives on their careers and lessons learned along the way.
Inspirational Ohio Supreme Court Justice presents keynote speech
The symposium’s key note speaker was Ohio Supreme Court Justice, Melody Stewart. A true pioneer, she achieved many firsts with her election to Ohio’s Supreme Court as an African-American woman and a Democrat. Justice Stewart has more than 30 years of combined administrative, legal and academic experience. Before joining the Supreme Court, she spent 12 years on the 8th Ohio District Court of Appeals, earning accolades for fairness and equity in the judicial process. She is also a music lover and avid piano player, having played since the young age of 5 years old. Read more from Cleveland Magazine about her history and accomplishments.
Sharing career experiences
The career discussion break-out sessions each lasted about 30 minutes, giving students the opportunity to learn about a variety of career paths. The team of Parker women offered perspective on the many different roles within the IT function and the importance of leadership and education.
Supporting inclusion and diversity
The company’s first business resource group, Peer W, was formed to support the attraction, development and retention of woman at Parker. The mission of the group is to cultivate the professional success of women by creating awareness, education and visibility across Parker’s organization. Peer W provides resources and support for women in all roles across the company. In support of Parker’s goal to provide an inclusive environment, business resource groups offer an opportunity for team members to pursue educational opportunities, engage and interact with business leaders and identify opportunities to promote career growth.

Engineering Alumni Shares Value of Motion and Control Lab Experience
Most thermal pads, also known as thermally conductive gap filler pads, thermal gap pads, or thermal gap filler pads, have many different layer materials or carrier substrate options to choose from. It can be confusing which layer is supposed to stay on the product and which layer gets peeled off and removed before application. In fact, it’s one of our customer’s most asked about questions and can cause a lot of confusion on the manufacturing floor.
So, which layer should you peel off and which should stay on the thermal gap pad? Read on to find out.
Parker Chomerics, like many thermal gap pad vendors, offers several different gap pad layer options that must be peeled away before the gap pad is installed into the application.
Think of a thermal gap pad as a sandwich of layers -- there is always a blue poly backing that keeps the gap pad together, but there are five additional carrier substrate options which provide the following benefits:
Woven fiberglass
The woven fiberglass carrier option provides reinforcement and a clean break / low tack interface surface, allowing for re-use of the thermal pad if necessary or for prototyping.
As you can see from the diagram, you peel off the liner to expose the woven glass carrier which does not get removed from the thermal gap pad.
Example: THERM-A-GAP HCS10G.
Aluminum foil with pressure sensitive adhesive (PSA)
The aluminum foil with PSA carrier’s primary function is to allow a pressure sensitive adhesive on the thermal gap pad to affix the thermal pad in place.
As you can see from the diagram, you peel off the liner to expose the aluminum foil carrier which does not get removed from the thermal gap pad.
Example: THERM-A-GAP A579.
Polyethylenenapthalate (PEN) film
The polyethylenenapthalate (PEN) film carrier permits the thermal gap pad to see a shearing motion and offers a clear, cost-effective dielectric film with fair thermal performance.
As you can see from the image at right, there is no clear film to peel off that exposes the PEN film carrier, which does not get removed from the gap pad.
Example: THERM-A-GAP 579PN.
Thermally enhanced polyimide
The thermally enhanced polyimide carrier permits the thermal gap pad to see a shearing motion and offers an excellent dielectric film with enhanced thermal performance.
As you can see from the image at right, there is no clear film to peel off, the polyimide carrier does not get removed from the gap pad.
Example: THERM-A-GAP 579KT.
No carrier
The no carrier or “un-reinforced” option allows the thermal gap pad to have high tack surfaces on both sides, allowing for the pad to be highly conformable, but it does make cutting and handling of the product more difficult.
Once the liner is peeled back, there is no additional carrier on the thermal gap pad, the pad is now exposed.
Example: THERM-A-GAP 579.
Blue poly diamond carrier
Lastly, the base carrier liner, shown in blue, is persistent on the bottom of all thermal gap pad options, and must be peeled and removed prior to installation of the thermal gap pad.
This blue carrier is necessary, as it keeps the gap pad intact and more easily to handle prior to installation. We recommend keeping this blue poly carrier layer on just until the gap pad is placed for the final time.

Viscosity vs. Flow Rate - Which Is Best in Thermal Interface Materials?
As a packaging OEM, it's likely you're under intense pressure to provide the best level of service to your end customers as possible, from entire processing lines to the smallest of critical parts. At the same time, keeping tabs on the range of critical parts and components specified for your builds can be a complex, time-consuming proposition, especially when it comes time to reorder.
Simplifying the process
One tool designed to simplify these processes and reduce paperwork for OEMs is digital asset tracking, such as with the Parker Tracking System (PTS).
This web-based asset tracking and management system combine part serialization with tagging and a range of part-specific information so that OEMs can track, organize, and manage their use of critical parts. As a cloud-based tracking solution, users have online access to needed documents like parts lists, manuals, diagrams, certifications and more. The result is easier tracking and management of critical parts, reduced lead time and complexity in ordering, and enhanced service, safety, and compliance features.
It's both a program and a technology that we pioneered just over a decade ago out of a long-term focus on providing superior service, convenience and value to supply chain partners and customers. Initially used to track and manage specifically engineered hose assemblies, PTS has expanded over the years to cover products across many of our divisions. Today, some 25 million assets in 62 countries and thousands of locations are being tracked and managed using PTS. Subscribers include distributors, OEMs, and end-users in the automotive, healthcare, oil and gas, food and beverage, and other market segments.
Get organized through digital automation
Packaging OEMs using PTS stand to gain greater convenience and better oversight because the system takes over much of the tedious parts-related paperwork that OEMs used to handle themselves, to keep customer-specific part and assembly data organized.
"A lot of the machines that get sold and shipped to customers still come with traditional parts manuals or books. Rarely are people receiving this critical data digitally, which makes maintaining it that much more challenging."
William Sayavich, technology manager, Global Services
PTS automates the process with the creation of unique PTS identification numbers, records, and corresponding tags for each specific asset, kit, component or sub-assembly made by Parker or a Parker business partner.
Each PTS tag contains four critical pieces of information: a unique 8-digit PTS ID number and machine-readable bar code assigned to the asset; the asset's assembly date; a customizable part number or bar code corresponding to the OEM; and reordering information. Labels can typically be personalized for the OEM with logos and other contact information.
PTS also can serialize kits or combinations of part numbers associated with specific builds using "master"-level PTS tags to manage the collection of specified parts assigned to one customer or one machine.
By scanning the PTS bar code via phone or handheld device, or manually entering the ID number into the PTS application using a web-connected computer, OEMs then have access to this information, including the detailed bill of material, certifications, and the specifications used to create the part or assembly.
PTS asset records are available 24/7, and some of the data can be accessed via mobile phone using the PTS Mobile app. And unlike printed parts manuals and books, PTS information also can be gated for specific users, allowing administrators to assign access to specific team members who require it.
The customers' value proposition
Much of the ongoing value of PTS is to the customer, who will find it easier to reorder genuine replacement parts without having to hunt for part numbers. Because the tag offers a bar code, the OEM can simply scan the tag to understand exactly what needs to be replaced.
Having easy access to exact components and assembly details is critical for OEMs and their customers seeking fast service or replacements for complex builds, as well as a greater understanding of the scope of critical components.
The biggest value of PTS for both OEMs and customers is its use on assemblies or kits containing multiple specific parts selected to make up that component for a certain application.
The labels are valuable because they identify the manufacture date and supplier of each component and give the end-user a simple, reliable, and accurate way to reorder the exact same part when it’s necessary. This means that even when the OEM turns a build over to an end-user, that customer still has full knowledge of the tracked parts within that machine, should they need to be replaced or serviced.

I have had many discussions with customers as to the value of using an ASTM elastomer compound description on their prints to define a specific application or elastomer requirement versus listing an approved Parker compound number.
Specifying a compound using the ASTM callout is a good start - it clearly defines what you want, it sets a minimum bench mark and it is easy for competitive vendors to understand what you are asking for. The ASTM standards also set specific test parameters which make it easier to do an "apples to apples" comparison between two compounds. However, over time here is what my customers have learned:
Know your operating requirements
1) The ASTM standards are very general; so when my customer defined a specific FKM they needed using an ASTM callout, they received a compliant material that just barely met the ASTM specifications but did not meet their actual operating requirements. The supplier provided my customer with their lowest cost material. The quality of the material was poor and inconsistent, but it met the ASTM criteria they requested. This customer saw a 15% increase in assemblies requiring rework plus the number of warranty claims rose due to seal failures. The twenty cents per seal my customer saved for their $48.00 application was offset by the cost of increased product failures which also resulted in unhappy customers.
Know the fluids your seals will be exposed to
2) The ASTM standard does not specifically list what actual chemicals the seal has to be compatible with as well as the operating conditions. ASTM tests compatibility based on Standardized Testing Fluids which are Oils, Fuels and Service Liquids. ASTM uses standard oils which are defined by IRM 901 and 903. Again, the ASTM standards are excellent for comparing compounds, but most people do not have their seals operating in the ASTM reference oils and many sealing applications are exposed to multiple fluids.
Know what your ASTM is calling out
3) Most of the engineers or purchasing people who reviewed or utilized an older drawing had no idea why the original engineer chose the compound or why they used the ASTM callout specified. I typically find that most companies do not know exactly what the ASTM standard is calling out.
So what is the best way to define and specify an elastomer? Most companies go through a technical process to specify, test and confirm that an elastomer is the correct choice for their application. All of the elastomers that were tested and approved for the application should be clearly listed on the drawing. In addition, the drawing should clearly state that the approved materials listed were tested to confirm their suitability for the application. All substitutes or new elastomers must be tested and approved by engineering prior to use.
If you have questions regarding the suitability of an elastomer for your application,consult and work with your Parker Applications Engineer. We offer a plethora of compounds to suit your application needs. Ask our applications engineers and chemists for guidance; their vast seal design experience spans multiple industries and applications to solve your sealing challenges.

It is very important to have specific information to select the proper Power Take-Off (PTO) to match the transmission on a vehicle. A PTO is not transferable from one vehicle application to another especially with different transmissions. PTOs are available in many sizes and provide various capabilities that are tailored to fit the specific context of the application.
The following ranges of categorized sizes of PTO Series are as follows:
It is recommended to begin analyzing a PTO application using pre-determined necessary technical information about the work output and installation requirements. Go through the following steps to specify a PTO.

Here are useful formulas to help Specify a PTO:
Figure 2 (Remote on top, Direct on bottom)
While not all information is always available, here is an information guideline that can get you started with the right information to help you select the right PTO for your application.
Application GuideIt is important to remember when the appropriate PTO has been selected through the concluded gathered information, review the application guide and make sure that all the necessary information has been included. When searching for a PTO in a catalog, please remember to read the footnotes as there may be additional information to consider for specifying a PTO. This can include transmissions not being able to withstand torque capacity of the PTO and the application or some other unique feature of the unit may be mentioned through the footnotes.

Whether you are running a process in a 30,000 L bioreactor in fed-batch mode, a 200 L continuous process, or have scaled-out (rather than up), you will start at small scale and look to increase the volume - scale-up - to some degree.
However, we are recognizing that some biotech companies aren't adopting single-use automated technology until the process reaches pilot scale. This can reduce the likelihood of a successful outcome or the speed of the development process, as process rework may need to be managed further along the manufacturing development process. In some cases, changes to inefficient processes may be more difficult to implement, especially if they have already been approved.
The adage "start with the end in mind" has never been more relevant. For scale-up to be successful, we recommend using the same automated single-use equipment, strategies and materials from the R&D stage through to manufacturing scale. That way, speed to market can be optimized through simplified technology transfer of optimal process. You will also avoid unexpected rework that may come about due to material compatibility or availability issues.
Start as you mean to go onSpeed to market is of critical importance, both from a return on investment point of view, but also with the benefits to patients in mind.
Having single-use automated technology in place at the R&D stage can make the move into the manufacturing stage more efficient.
The benefits include:
And, if you use single-use technology during R&D you can also benefit from:
However, there are a few common pitfalls to avoid, which include making incorrect assumptions regarding how processes will behave at larger scale.
Ensuring successful scale-up in single-use bioprocessing webinarParker Bioscience Filtration is delivering a webinar on November 12th, 2019 which will help biopharmaceutical manufacturers build a strategy for effective scale-up of filtration and single-use processes that will facilitate technology transfer, in order to avoid delays in commercialization caused by inconsistent scale-up of a single-use process between R&D and manufacturing.
It will explain how to conduct a small-scale filtration trial using an automated single-use system at laboratory scale and examine the advantages this provides.
The webinar will also further explore the benefits of single-use technology in both R&D and manufacturing, and consider how to ensure successful implementation of single-use automation from laboratory scale through to large-scale production.

The difference between Machine to Machine (M2M) and The Internet of Things (IoT) can be confusing. While both M2M and IoT involve sharing data and can be connectivity solutions for enterprises, they are different schools of solutions mainly varying in the way they achieve connectivity.
There are several distinct differences between the solutions when it comes to their basic principle and applications. M2M refers to direct communication between devices such as machines, smartphones and appliances. The communication itself is completed using wired or wireless communication channels, whereas IoT is based on the fundamentals of sensors that can collect and analyze data in real-time. This connectivity of sensors can occur without the intervention of humans.
To map it out and draw a connection between the two: IoT is simply the “bigger vision” of connectivity and is fueled by the advancements of M2M applications. The main deliverable of M2M is to enable businesses to manage and collect data remotely by connecting their device(s) to the cloud. IoT, on the other hand, is a mass-market technology that applies to both consumers and enterprises. Enterprise IoT is increasing in popularity and takes business communication one step further by facilitating asset tracking and management, such as Parker’s Mobile IoT for off-highway equipment.
As the name implies, M2M connects machines to machines, whereas IoT takes machine-to-machine connectivity, integrates web applications and connects it to a cloud. While M2M employs isolated systems of sensors and records of remotely collected and measured data, IoT converges disparate systems into a comprehensive system to enable new applications. IoT steps it up by integrating device and sensor data with big data, analytics and other enterprise mobile applications. Comprehensive achievements like these are rarely captured by M2M systems on their own.
IoT not only provides prognostic maintenance but also improves business processes and operations. For instance, Parker’s Mobile IoT solution records and stores all data in the cloud, allowing visibility and adjustments to machine operations in real-time. Users can access the performance data remotely, making it easy for OEMs and their customers to collect and analyze data sets to identify usage trends and field-based problems with unparalleled intellectual design and insight.
M2M IoT Direct communication between machines Sensors automation and internet platform Supports point-to-point communication Supports cloud communication Devices don’t necessarily rely on an internet connection Devices rely on an active internet connection Mostly hardware-based technology Both hardware and software-based technology Normally communicate with a single machine at a time Many users can access at one time over the internet A device can connect through mobile or other networks Data delivery depends on the internet protocol (IP) networkSimply put, IoT is more than device connectivity, as it is the network of connected devices. The chart below demonstrates a side-by-side comparison of the two solutions to more easily understand their distinct differences.
Undeniably, M2M and IoT share common aspects. The core similarity is that both provide remote access to machine data and both exchange information among machines without human intervention.
ConclusionIn a nutshell, both technologies enable machines to communicate, collect, store and exchange data; autonomously lead to corresponding decisions, and perform tasks with minimal human intervention. Yet, as we can see, M2M and IoT are not synonymous.
The two are different solutions for enterprises and provide different levels of data exchange and collection. M2M and IoT primarily vary in terms of how they achieve connectivity, what they aim to connect, how scalable they are and how the data is utilized. Both, however, have a focused geared toward a more connected and “smart” world.

The Internet of Things (IoT) – referred to by some as Factory 4.0 or Industry 4.0 – is ushering in a revolution on the factory floor -- one with clear implications for HVACR contractors and distributors.
With the adoption and deployment of smaller, less expensive sensors, the development of advanced analytics and the commodity storage options provided by the cloud, companies everywhere are embracing the opportunities for IoT’s transformative business applications, HVACR companies among them. Why? It’s a big business.
U.S. manufacturers are already delivering or planning to deliver, products with IoT capabilities. Connected HVACR solutions will offer the kind of contractor value that can lead to competitive advantage by offering customers potential benefits like these:
• The tracking of system performance
• Predictive maintenance
• More predictable downtime
• Compliance with environmental regulations
• Custom configurations
• Analysis/drill-down data that allows contractors to identify performance issues
• Mobile device functionality for ease of monitoring, intelligence gathering, and analytics
Download our white paper How to Capitalize on HVAC/R Trends to Drive Business Growth to learn what HVAC/R contractors and distributors must do now to capitalize on new and emerging IoT technologies in the market place.
Some of the major players and the residential contractors that support them are still in the ‘early-adopter’ stage. Security products like locks and window or door sensors, as well as IoT lighting solutions, are the most popular. With the advent of Alexa and other voice command hubs, there’s more interest in items for convenience, like connected outlets.
Commercially, IoT-enabled buildings are leveraging internal and external information sources to create actions and workflow that benefit energy efficiency, tenant comfort, building health and/or operational excellence.
This presents an immediate opportunity for HVACR contractors to embrace IoT technologies and the creation of IoT-enabled buildings. One of the major benefits that IoT-enabled buildings will create for HVACR contractors is the advantage of information for remote diagnostics, troubleshooting, and solving building issues before they move to the critical stage. In addition, more and more customers will expect upgraded levels of IoT-enabled control over devices and the ability to view more comprehensive operational data.
On the residential end
A growing number of HVACR residential customers are not monitoring how well their system is operating overall and when it’s time for a cleaning. IoT enabled systems can email the customer in real-time if there is an urgent issue with a component or when it’s time to change their filter.
IoT enabled thermostats can also communicate with the furnace and air conditioner. Once set up, it will send notifications to designated email addresses for anything from regular maintenance reminders to replacing filters, as well as alarms if there is a problem with the equipment.
Currently, IoT products gaining the most traction are wireless Energy Management Systems (EMS) and associated sensors and controls, smart thermostats, mini-split Wi-Fi controls, and most recently, Wi-Fi lead detection and freeze detection sensors.
Where HVACR partners and collaborators are at today
As technology progresses on both the residential and commercial sides, HVACR contractors will have to undergo additional training on the new tools available to them. This is a role that distributors can fill. Contractors may also have to rethink their customer relationships. With continuous access to data that matters to their customers, relationships will change from reactive (dealing with breakdowns) to proactive and long-term.

How Collaboration With Manufacturers Will Help You Perform Better
We’re in the midst of our own gold rush of sorts. Rather than fleeing to California in search of prosperity through extraordinary and precious assets, businesses are looking above to achieve their good fortunes. The cloud as it’s become known has empowered organizations with vast amounts of invaluable data to better serve the needs of customers while increasing the all-important bottom line.
Every second of every day, billions of people are seeking information through computers, mobile devices and the Internet of Things (IoT). This translates to massive amounts of unstructured data being collected and stored with the intent to leverage these variables to support decisions and actions that best satisfy a need or demand. We have come to know this as the big data boom.
Retrieving data involves a similar approach miners used way back when for discovery and exploration. The process involves mining, processing, refining and extracting unfathomable amounts of information with hopes of discovering valuable intelligence into customer behaviors and trends and all facets of business performance. As with the California Gold Rush, organizations across industries – from manufacturing to finance to healthcare – are in search of these golden nuggets of information, to achieve a significant advantage over the competition.
Demand for meaningful dataOur reliance on the internet has never been greater, and our accessibility has never been easier. According to a 2019 study by Pew Research, 81 percent of Americans are going online on a daily basis, with half utilizing the internet multiple times throughout the day. The barrage of IoT devices presents both extraordinary opportunities and difficult challenges.
As of 2017, an estimated 2.5 quintillion bytes of data was being generated and that number will only accelerate. By the year 2025, the International Data Corporation (IDC) believes IoT devices will generate more than 79 zettabytes (ZB) of data. That’s a whole lot of information to sift through, and therein lies the challenge for businesses. A majority of this data is unstructured, meaning it can come in any size, shape or form, making it extremely difficult to manage and analyze. So then, as the internet rapidly grows, how can organizations effectively manage data to gain valuable insights?
It’s true you can have too much of a good thing. In relation to data, consumers and businesses are generating so much of it, there’s a formidable strain being placed on the internet infrastructure. So then, as cloud technologies evolve, how can companies alleviate the data pressure and effectively collect and manage valuable insights? That’s where cloud computing plays a role in solving the data crunch.
Cloud computing, better known as “the cloud,” serves as a virtual bridge to seamlessly transport data from IoT applications to a desired destination. Variable expenses, tailored-built capacity, imminent deployment of applications and exceptional speed and agility are several key advantages and benefits as to why organizations favor this approach to collect, process and store tremendous amounts of data. The desired destination to house all of this data is in a public cloud that we refer to as a data center.
Data centers proven critical to the success of IoTData centers are the keystone of the big data boom. These technology havens are vital to organizations as they store, communicate and transport the information we generate each and every day. However, most data centers today are outdated infrastructures with inefficient systems, having failed to adapt to emerging technologies. This notion, as a result, limits the capacity to produce meaningful information.
As data centers transition to satisfy the growing demand, processes within its ecosystem will need to be modernized. Racks of servers and computing equipment require abundant power demands, making them susceptible to extreme heat. That’s where innovative cooling systems can play a role in ensuring these supercomputers continue to operate without overheating.
Air-based coolingUnfortunately, traditional data center cooling systems waste a lot of energy, money and prove insufficient. One of the most common methods is air-based cooling, more specifically, cold aisle / hot aisle. Simply put, the configuration is to conserve energy and lower cooling costs by managing air flow through the separation of cold air from hot air.
The cold aisle/hot aisle process involves server racks being lined up in alternating rows with cold air intakes facing one way and hot air exhausts facing the other. In theory, this creates a convection system where server racks cool themselves, but this does not always work, causing more cold air to be pumped into the room. While this approach will bring the room temperature to an ideal setting, excess cooling capacity breeds hot spots in the data center. When all of the cooling units are running simultaneously, this creates a surplus of air flow, which causes hot spots to develop and form in racks and across equipment. Instead of cool air being pushed past servers and then staying by the servers, that air is pushed up and away from the servers.
Liquid-based coolingAnd this brings us to liquid-based cooling. Viewed as the successor and far more efficient solution to air-based cooling, this technique allows specific system components to be cooled to a greater degree utilizing water. Liquid-based cooling is used to cool the hot side of the server rack to bring the temperature down. Since water conducts electricity, the liquid never touches the actual components themselves. Basins accommodate water, which is carried through hoses and into cooling tower pumps, then runs alongside the server. This helps keep the temperature of the components inside the server rack cool.
Now, there is a conflict with this approach. There will always be that risk of water leaking, especially at the point of connection between components, which spells disaster for server racks. Connections are ever so critical for continuous operations of liquid-based cooling. Companies demand a connection leveraging maximum reliability and efficiency coupled with durability and compact design. Most importantly, eliminating the chance of a drip, spill or leak. And that’s where Parker’s liquid cooling coupling solutions satisfy the need.
Featuring an advanced internal design and robust functionality, these couplings incorporate non-spill valving, meaning no spillage during connection and disconnection. The key is a flat-sealing valve design, preventing any type of fluid loss against sensitive electronics and all electrical connections. This ensures the highest level of compatibility with the broadest range of liquids and the application environment.

The last thing one wants to worry about is a loud noise coming from their truck and not knowing why it is happening or where it is coming from. Without proper maintenance and potential improper installation, the Power Take-Off (PTO) itself is subject to making noises that may sound like whining, clattering, clicking and grinding. It is important to note that the sounds one may hear of these noises may not be from the PTO itself but from somewhere else in the system. PTOs also normally create torsional vibrations found in diesel engine applications that have led companies to develop technologies to help mitigate and smooth out those expected vibrations.
PTOs now in the market have focused on reducing noise and making sure that drivers are more comfortable allowing them to get their work done. Parker Chelsea has developed QT GearTM technology, a solution to mitigate noise, that can be applied to nearly all PTOs that are engine driven by a live PTO drive gear in the transmission. Examples of some PTOs featuring the technology include the 249 Series and the new 210 Series launching in the fall of 2019.
Even though the technology is in place, there still may be unique sounds coming from the PTO itself. Here is more information on what might be causing the specific noise types you hear if the PTO is the root cause of the noise.
WhiningWhen looking into a new installation and hearing a whining noise coming from the truck, a potential cause could be from the PTO having an improper backlash. What improper backlash entails is less than .006” clearance between the (transmission) PTO driver gear and the PTO input gear as measured at the pitch line using a dial indicator. This can cause rapid heat buildup and gear tooth breakage. For an existing installation, the whining noise (pitch sound) change could indicate a possible bearing failure.
A probable cause for hearing a clattering noise coming from the truck with a new installation can be the result of the excessive backlash. Excessive backlash is created from more than .012” clearance between the (transmission) PTO driver gear and the PTO input gear as measured at the pitch line using a dial indicator. This will lead to eventual gear tooth failure from insufficient contact. In the scenario of an existing installation, it is important to make certain the cause of the noise is from the PTO. It can be determined by disconnecting the driven equipment and running the PTO. If the source of the noise is determined to be from the PTO, make sure to check the bearings and shifter mechanism.
ClickingClicking is most commonly caused from a damaged gear tooth. The clicking noise itself typically indicates that either one or two gear teeth are damaged only. The frequency of a click can help indicate the size of the gear at issue, with a fast click being due to a small gear and a slow click being due to a larger gear. If a grinding noise is heard, this would be an indication that all the teeth are damaged.
The common cause of grinding noise can be traced to operator abuse when engaging the PTO. To properly engage for a mechanically shifted PTO, the operator should depress the clutch and then wait for the transmission gears to come to a stop before engaging the PTO. To properly engage for a “hot shift” PTO, the operator should make sure the engine RPM’s are below 1200 before engaging the PTO. For both new and used installation, a grinding noise could indicate that the shifter cable or lever isn’t adjusted correctly. Make sure to check for the correct adjustment of the clutch brake on the transmission.
Noise on Allison Transmissions
Typically, the combination of diesel engines, automatic transmissions and PTOs can result in significant noise via rattle and/or vibration. It becomes more recognizable when using heavy-duty transmissions behind turbo-charged engines and is enhanced by using neutral lock up. (The neutral lock up compresses the disks within the transmission torque converter, eliminating the cushioning fluid that is normally found between these disks.) Please note that this noise is not harmful to the PTO or the transmission. When the engine RPM is raised or lowered, or a load is applied to the PTO, the noise will usually disappear and go away.
ConclusionPTOs generally do release torsional vibrations and therefore can be heard on a truck application. Companies have been putting in place their own technologies to help mitigate noise from these vibrations. Even with general PTO noise, the rare whining, clattering, clicking and grinding noises may occur. One will have to distinguish from a subjective matter if the PTO sounds like it is making one of these noises and from there will need to be determined if that noise is from the PTO or another part of the system.

New Dump Pump Revolutionizes the Dump Truck Market with a Small Frame
As an engineer, the responsibility to adopt not just the latest, but the safest technologies, never goes away. Protecting people and machinery has become, quite simply, industry’s number one priority. Safety first. Always.
Factory automation is certainly no exception. Here, major advances have fuelled greater focus on smarter controls and increased integration of smart devices and safety componentry. Included in this are the latest pneumatic solutions, which nowadays form a core part of safety controls for implementing the preventative technical measures needed to ensure machine safety, including clamping, blocking, exhausting and holding equipment in place.
But hold on a moment, what actually classifies a product as a safety component? Well, as with all things related to machine safety, the best place to find out is the Machinery Directive, which states that a product is deemed to be a safety component when it is tested and verified to provide specific safe function for a pre-determined period of time in a given state.
The Machinery Directive also offers clear distinction between safety devices and standard pneumatic components deployed in a safety circuit. Notably, the term ‘safety component’ does not imply the actual reliability or safety level of the component. Those products offered as safety-rated must undergo stringent requirements for certification, testing and approval. As a further point, the Machinery Directive does not prescribe the use of safety-rated componentry, it merely provides a description of the conformity assessment procedures to market a product as safety rated.
So, how is it best to determine what level of safety is required? The answer: perform a risk assessment. Three steps are involved here: analysis, evaluation and reduction. The first step, risk analysis, also requires engineers to estimate risk and determine the performance level required (PLr).
After the PLr is established the performance level (PL) will need to be calculated based on safety categories that are established in line with factors such as a measure of diagnostic capabilities (DC) for the control system, the meantime to dangerous failure (MTTFD) and common cause failure (CCF). In combination, these inputs will define the level of a given safety function.
In tandem with the strategy set out here, peace-of-mind can, of course, be found by specifying safety-rated products from a reputable supplier. After all, as machine builders will be well aware, the price of non-compliance can be extremely costly.

4 Ways to Achieve Required Safety Levels with Pneumatic Exhaust Valves
The last thing one wants to worry about is a loud noise coming from their truck and not knowing why it is happening or where it is coming from. Without proper maintenance and potential improper installation, the Power Take-Off (PTO) itself is subject to making noises that may sound like whining, clattering, clicking and grinding. It is important to note that the sounds one may hear of these noises may not be from the PTO itself but from somewhere else in the system. PTOs also normally create torsional vibrations found in diesel engine applications that have led companies to develop technologies to help mitigate and smooth out those expected vibrations.
PTOs now in the market have focused on reducing noise and making sure that drivers are more comfortable allowing them to get their work done. Parker Chelsea has developed QT GearTM technology, a solution to mitigate noise, that can be applied to nearly all PTOs that are engine driven by a live PTO drive gear in the transmission. Examples of some PTOs featuring the technology include the 249 Series and the new 210 Series launching in the fall of 2019.
Even though the technology is in place, there still may be unique sounds coming from the PTO itself. Here is more information on what might be causing the specific noise types you hear if the PTO is the root cause of the noise.
WhiningWhen looking into a new installation and hearing a whining noise coming from the truck, a potential cause could be from the PTO having an improper backlash. What improper backlash entails is less than .006” clearance between the (transmission) PTO driver gear and the PTO input gear as measured at the pitch line using a dial indicator. This can cause rapid heat buildup and gear tooth breakage. For an existing installation, the whining noise (pitch sound) change could indicate a possible bearing failure.
A probable cause for hearing a clattering noise coming from the truck with a new installation can be the result of the excessive backlash. Excessive backlash is created from more than .012” clearance between the (transmission) PTO driver gear and the PTO input gear as measured at the pitch line using a dial indicator. This will lead to eventual gear tooth failure from insufficient contact. In the scenario of an existing installation, it is important to make certain the cause of the noise is from the PTO. It can be determined by disconnecting the driven equipment and running the PTO. If the source of the noise is determined to be from the PTO, make sure to check the bearings and shifter mechanism.

5G, which stands for the “fifth-generation” of wireless technology, is expected to change the face of connectivity as we know it, offering faster downloads and better network reliability, which translate into improved efficiency; lower operating costs; and fewer risks, especially in the heavy off-road equipment industry.
For devices and applications that demand real-time connections, such as those geared towards Internet of Things (IoT), the capabilities and benefits of 5G are vastly promising. The current network, 4G, is inadequate for handling the data load from the ever-increasing number of sensors and connected devices coming online, limiting what IoT is truly capable of achieving. The combined momentum of 5G and IoT will cause the number of internet-connected devices to accelerate even more rapidly in coming years than in the past. For instance, 5G network speeds are anticipated to be as high as 10-20GB/S, allowing for rapid transmission of data between connected devices. 5G also utilizes a multi-band spectrum approach that leverages both high-, mid-, and low-bands, which provides greater coverage in both urban and rural communities.
It’s not clear if many of the IoT applications that are coming in the short term need the higher bandwidth offered by 5G. However, we do know that an IoT enabled piece of equipment transfers very large files to the cloud for processing, and it takes time for uploading through the different layers of IoT structure. However, it is clear that 5G data speeds will reduce the amount of time in data transfer and result in more timely decision making.
Lower latency
In conjunction with increased speed, 5G will enhance mission-critical IoT applications that require maximum reliability and responsiveness due to the reduced latency. For applications where low latency and ultra-fast download speeds are not necessary, 5G will still provide needed support in areas with high energy efficiency requirements and lower power consumption goals, such as smart cities. For off-road equipment or mobile equipment, the low latency in 5G connections could allow new technologies to be used by off-road equipment transmitting braking or directional information to one another such as in the mining industry. In a truck platoon or other similar automated vehicle connection, it could improve the reliability and speed of the exchange of information between two or more vehicles. Because the data is transferred faster, the systems controlling the vehicle can react sooner - braking if needed or turning - to ensure safe operations.
Higher capacityOEMs and fleet managers of heavy off-road equipment are increasingly seeking to digitalize and automate their operations to increase productivity, enhance operator safety and reduce cost. 5G furthers the conceptual ideas of using IoT solutions to remotely operate machines from a control room and collect machine performance data to optimize the use of the equipment, for example. This creates a need for reliable, high-capacity wireless connectivity in order to support multiple applications and services simultaneously. 5G will provide much more network capacity by expanding into new spectrums, such as millimeter wave (mmWave), which have not yet been used for commercial broadband traffic prior to the deployment of 5G.
There is a lot we don’t know about the impact of 5G. However, there is much debate about whether or not autonomous mobile equipment will over-rely on telecoms networks. Autonomous vehicles rely on detailed maps and sensors, lidar and optical radar that together creates a detailed picture that they then look for anomalies and take whatever action is necessary. To achieve this, a lot of high-performance processing will be carried out on the vehicle.
The 5G discussion centers around the amount of data usage. It has been estimated that autonomous equipment will generate up to 4 terabytes of data a day, but only a tiny fraction of that information (maybe as little as 0.1%) will need to be shared with the network. Because of this, self-driving equipment may depend more on on-board processing than the cloud. Therefore, some believe that real-time connectivity will be beneficial but not essential. Telecoms networks will be used for non-real time updates to and from the equipment, but bandwidth requirements for these services is expected to be relatively low. Autonomous machines is definitely an area that needs to be explored a bit more before we make a clear connection between the two technologies.
How will 5G impact your IoT plans?Within the next 10 years, IoT networks will face prominent challenges because the networks will become denser, more complex and heavily loaded than today. 5G implementation can be one of the technological upgrades to overcome these issues. The future connectivity standards will focus on improvement in connection density to handle the massive number of IoT devices, pervasive coverage to reaching challenging locations, low-power consumption and reducing network complexity. Parker is at the forefront of this ever-evolving technology, so click here for more information about our mobile IoT solutions for off-road equipment.

In clinical diagnostics, the fastest-growing segment is point-of-care testing (POCT). POCT consists of medical diagnostic testing performed close to the patient, instead of a traditional centralized hospital lab or offsite laboratory. Driving this growth and market demand is the ability to bring convenient testing and almost immediate results to the physician and patient. The market is also very broad, as point-of-care tests can be developed for many clinical indications including infectious diseases, glucose, cholesterol, cancer (tumor marker testing), urinalysis, diabetes, cardiology and blood screening. The ability to quickly diagnose a wide variety of diseases closer to where patients are enables improved patient outcomes, increased patient access and lower total cost of care. This market shift is changing clinical diagnostics device manufacturers' needs and approaches to design. This blog investigates a common POCT technique and the innovative components being designed specifically for these devices.
Download this application note to learn how to streamline point of care instrument development.
Molecular diagnostics technique
Molecular diagnostics techniques have become a common enabling technology in the point of care market. In its most basic terms, molecular diagnostics typically involves matching the DNA found in a patient sample (the patients own DNA or DNA from organisms in the sample) to target disease in a DNA test cartridge. If no match is found in the test, the patient doesn't have the targeted virus, bacteria or cancer marker, but if a positive match is made the patient can be quickly treated for that illness. Molecular diagnostics enables smaller diagnostic devices because all of the chemistry can be completed in a small compact cartridge. It also provides the ability to detect multiple targets at one time with one sample, referred to as multiple testing. Below is a basic example of a multiplexed point of care instrument by using Molecular Diagnostics techniques, and the types of components that are often involved in this circuit.
In the above diagram, you see a simplified fluidic circuit where a multiplex test would be completed in a micro-fluidic cartridge. In this example system, fluids in the cartridge are piloted by air pressure supplied by an internal pump and controlled using various valves and pressure control methods. This circuit includes the Parker Helix pump (a miniature high-pressure pump) to supply the gas pressure to an accumulator volume to store compressed air. A Parker OEM-EP pressure controller or VSO LowPro proportional valve is then used to maintain steady pressure in the accumulator for precise control of the microfluidic circuit. Miniature solenoid valves such as the X-Valve, C7, Series MX, are used to dispense specific reagents and move the sample through the process. These fluidic components have a compact and efficient design which helps reduce instrument size and are offered with a variety of features to meet the needs of the application. Two specific parts of this fluidic system that will be examined in greater detail are the Helix Pump and the X-Valve.
The Helix Pump
The Helix pump is a compact, high-pressure pump that is designed to enable the smallest and fastest point of care instruments with a width of only 49 mm [1.9"] height of 84 mm [3.3"], and a length of 87 mm [3.5"]. The Helix pump delivers more than 5.5 LPM flow and pressures up to 100 PSI to pilot micro-fluidic cartridges with narrow passages. This compact pump was developed specifically for point of care test devices with limited available space and high-performance demands. The pump also includes an integrated Parker X-Valve to relieve pressure on the pump between cycles, this integration further reduces the footprint of the pneumatic system.
The increased performance of the Parker Helix pump also enables operation in challenging high-altitude environments with lower atmospheric pressure, allowing POCT systems to function in a broad geographical range, further increasing patient's access to life-saving diagnostic testing. The Parker Helix pump uses a controllable brushless DC motor designed to operate at a wide range of speeds to reduce noise in a system during times of lower demand. Additional accessories include a filter muffler, which provides further noise reduction and filters debris.
The X-Valve
The X-Valve is described as a miniature valve but it is tiny — measuring 7.87 mm [0.31"] width, 12.20 mm [0.48"] height, 23.37 mm [0.92"] length, and weighing only 0.16 oz (4.5g).This valve is ideal for portable applications with limited space and power (power requirement from 0.5W to 1W). The X-Valve was designed to reduce system size and weight while providing pneumatic solutions in one package. This valve includes various mounting options available to ensure compatibility with any point-of-care system. The X-Valve is designed for direct tubing or manifold mounting, and can even be placed directly on a PCB. These options allow for mounting in tight limited space and numerous valves to be mounted together.
Conclusion
The demand for more point-of-care testing has driven medical device manufacturers to design smaller components and devices with the capability to replace traditional in-vitro diagnostics systems. The advancements in molecular diagnostics and miniaturization will continue to change the industry in the future. These changes will make testing more convenient and generate immediate results for patients and physicians; this will decrease the cost of care and increase early detection to improve patient outcomes. Point of care testing is one of the most promising solutions to serve an expanding population by increased patient access, improved patient outcomes with early detection, lower total costs and overall improving the lives of patients.

Seals made of the fluoropolymer PTFE are used where many other sealing materials (such as rubber elastomers, polyurethanes, fabric-reinforced elastomer seals, etc.) reach their limits in terms of requirements such as temperature range, chemical, friction and wear resistance. That is why PTFE is the most frequently used fluoropolymer in challenging sealing applications. Parker Prädifa produces seals made from pure PTFE and numerous modified compounds with diameters of up to 4.5 meters using economical machining techniques.
Polymer materials like PTFE, PEEK, TPU and selected elastomers are suitable for machining such as turning or milling. This makes it possible to economically manufacture both larger and smaller volumes because no additional tooling costs for molds are incurred.
Parker Prädifa has been producing complex machined polymer seals with diameters of up to 3 meters for decades. In the light of a growing demand for increasingly large seals Parker Prädifa has continually developed the manufacturing technology of machining further and is now able to offer diameters of up to 4.5 meters at the highest level of quality. The production of even larger diameters is currently in the pipeline.
Engineering, testing, manufacturing and quality assurance using state-of-the-art methods
The production of large seals for challenging applications is not simply a matter of scaling up know-how of traditional seal design and machining. The reason is that XXL sizes not only pose particular handling challenges in the manufacturing process, but do so even earlier, in the design and testing stages.
The evaluation of the performance of large-scale seals under various load and temperature conditions requires sophisticated simulation models. Particularly critical factors to be considered in the design of large seals include thermal shrinkage and expansion. In addition, even relatively low pressures may result in extreme forces acting on the seals, leading to considerable deformations or even seal failure.
As damage caused by seal failure and leakage may be particularly severe in the case of large seals, reliable sealing functionality must be comprehensively validated prior to their utilization in the respective application. Parker Prädifa uses virtual prototyping for validation. Due to the advanced method of virtualization utilizing sophisticated FEA models costly tests with real-world parts can be avoided and development cycles significantly reduced.
Parker Prädifa ensures top quality of XXL sealing solutions using quality assurance technologies developed in-house. Picture: X-ray inpection of large-diameter seals.

You've heard about digital asset tracking, and its ability to serialize parts for OEMs when they order them. But what about the longer-term benefits of these digital asset management programs? How can they help OEMs and their customers down the road?
Asset tagging and management systems
Asset tagging and management systems, at their most basic level, are designed to help make the identification, preventative maintenance, and replacement of individual parts an easier task for OEMs and their customers.
In our case, we've developed a system called PTS, or Parker Tracking System, capable of providing distributors, OEMs, and their customers all the information they might want to know about the parts or components within their machines. The idea is to provide end-users greater clarity on these components when it comes to construction, compliance, maintenance, troubleshooting, and replacement.
OEMs can apply PTS solutions to drive increased value to their customers while recognizing benefits in areas such as production efficiency, quality, safety, and data analytics.
"This multi-layered, digital information, which can be critical to doing business, unfortunately, is still lacking for some organizations."
William Sayavich, technology manager for Parker Global Services
Download our report, Tracking and Optimizing Inventory Control: Two Purchasing Tactics for Packaging OEMs and learn how implementing key strategies will streamline the ways OEMs look at their inventories and help save time, effort, and money in the process.
The power of digital records
Beyond the simple tag or label, however, OEMs also have the option to acquire more detailed information about the components they’re using and supplying, in the form of the digital records. These digital records contain more detailed information about each product than could possibly be included on a label, such as material certifications, parts used within the assembly, lot traceability, test reports, maintenance schedules, schematics, and more.
And what if those digital records also could organize for customers all the documentation needed with their builds, like updated parts manuals, certifications, maintenance schedules, warranties, and even photographs, directly tied to the components in question?
Capabilities like these might not be commonplace among packaging OEMs today, but they provide a powerful upgrade to printed, static and generic records for critical components like pneumatic controls, actuators and matched connectors.
Where digital assets come into play
PTS, for example, serializes and tags components for packaging OEMs. Tags and records are created prior to delivery, using the OEM's private label if requested, and then these records are seamlessly transferred to the OEM's PTS account and assigned to end-user builds.
This serialized information then serves as the foundation for a variety of component- and performance-related insights OEMs can record and track after builds are put into service.
End-users benefit from PTS tags and records too: Because each asset tag can be private-labeled with the OEM's contact details, customers never have to question who to contact for service and exact OEM-quality replacements. And should they need to troubleshoot specific components within systems or compare one assembly's performance to another, PTS records can provide them a roadmap.
Perhaps one of the most valuable features of PTS is that OEMs have a platform for updating their records as builds are completed, altered, commissioned and serviced, and when performance-related events occur. Tracking life cycle performance for specific parts helps OEMs and their customers understand use and performance patterns and develop best practices over time.
PTS also can document key system changes, like routing and plumbing modifications, that vary from initial designs but reflect needed improvements. And because each PTS tag contains a manufacture date, it can be used to drive proactive preventive maintenance for the end-user. This, in turn, accelerates the MRO life cycle, keeping OEM machines running efficiently, longer.
Through all of these features, PTS is much more than a simple tag with a bar code. It's a life cycle reporting tool that gives OEMs greater oversight and control of the critical components in their builds and their performance over time.
A better customer experience
Much of the ongoing value of PTS is to the customer, who will find it easier to reorder genuine replacement parts without having to hunt for part numbers. Because the tag offers a bar code, the OEM can simply scan the tag to understand exactly what needs to be replaced.
“So many of us make our future purchasing decisions on how an OEM or a manufacturer deal with us in a time of crisis, such as when something breaks. If you can create a truly outstanding experience for them, there’s a good chance you will retain that customer.”

Combination electromagnetic interference (EMI) shielding and weather gaskets, more commonly known as EMI shielded combo strip gaskets, are an excellent choice for a variety of applications that require a resilient, highly conductive sealing solution of knitted wire mesh with the integration of an elastomer for weather sealing. Typical applications include electronics cabinet doors, telecommunication trailers, wing panel gaskets for the protection against lightning strikes, and EMP specified requirements and sealing of shipboard and EMI.
There are five major features to consider for EMI shielded combo strip gaskets: the elastomers available, the metals available, the various mesh knit densities available, the various profile geometries available and the option of an overmolded gasket.
1. Variety of elastomers availableElastomers are available in a silicone sponge or solid, or neoprene in sponge form to meet customer needs such as closure force, fluid resistance and NASA outgassing requirements. Elastomers allows for an increase in gasket life and reduces the overall ownership cost. Three specific design parameters are the most important variables to take into consideration when evaluating elastomer choices. These criteria are fluid exposure, temperature requirements and necessary compression characteristics of the material. Generally, solid elastomers are used in conjuncture with cast or machined surfaces due to their larger force requirements for deflection. Sponge offerings have less force requirements for deflection and are therefore typically used in conjuncture with sheet metal enclosures.
2. Broad range of metal alloys offeredA broad range of metal alloys are offered to meet the requirements of electrical and galvanic corrosion. This also makes it possible for customers to meet budgetary needs by using Monel (Ni/Cu alloy), Ferrex (SnCuFe), aluminum, or stainless steel.
3. Various mesh knit layers available
Various mesh knit layers are available to meet with the required electrical performance. Military applications will require multiple layers to ensure maximum protection while in less extreme applications, less layers are needed. These variations reduce gasket replacement schedules and improve their durability, allowing them to be handled during in-field installation. Most critical of these criteria include galvanic compatibility, electrical
performance, overall gasket durability and temperature range requirements.
There are round, square, or rectangle profile geometries available that allow for design leniency for application in specific performances. Which geometry you'd choose depends on the criteria necessary to the application, including, but not limited to, gasket deflection percentage, necessary compression characteristics of the material, application load available for gasket deflection and planned gasket affixation method.
5. Bonded vs. overmoldedThese combo strip gaskets are available in both bonded or overmolded version for tiered performance options. If needed, overmolded gasket can be used but only for wing panel applications.

The Internet of Things (IoT) is changing human lives and the way companies operate by continuously enhancing how we connect equipment. When the topic of IoT is discussed, the conversation typically centers around cloud computing and big data analytics, but sensors and gateways are just as much at the core of IoT. In fact, sensors are arguably the most critical element in IoT applications since they are the component that makes the devices “smart”. So how exactly do those sensors paired with the other IoT elements such as gateways create a framework that acts as a central nervous system?
Within the vast array of devices that compose the IoT world, there is a growing number of small, sophisticated sensors that together are transmitting signals like those of the human nervous system. In the human body, the central nervous system collects continuous streams of sensory data and transmits that information to the brain, where it is processed. Like the human body, an IoT gateway serves as the connection point between the cloud and controllers, sensors and intelligent devices. All data moving to the cloud, or vice versa, goes through the gateway, which can either be a dedicated hardware appliance or software program.
For instance, for fleet equipment companies, each piece of equipment is part of an entire connected system where the sensors continuously submits and collects data and send it to the gateway to preprocess before it goes to the cloud to be analyzed. To minimize the volume of data that needs to be forwarded to the cloud, an IoT gateway aggregates the data, which can have a big impact on response times and network transmissions, before sending it to the cloud.
As the number of devices and sensors grow in an IoT solution, so does the number of communications that will take place over a combination of public and private networks. Communications between the ‘things’, the gateway and the cloud therefore must be secure in order to prevent any data tampering or unrestricted access. Therefore, the data between the sensors, gateway and cloud is encrypted from end-to-end to preserve confidentiality, integrity and authenticity. In other words, only the IoT device and receiving cloud service hold the cryptographic keys and the gateway acts as an illiterate messenger, passing along messages that it can’t decipher.
A gateway’s role in evaluating system performance and device control
As you can see, within an IoT system the cloud infrastructure is just as important as the devices themselves. IoT devices are no good if they can’t connect to the cloud. For instance, the gateway Parker utilizes for Mobile IoT, is an IoT solution specifically designed for off-road equipment OEMs and fleet managers. This gateway can be used with any J1939 CAN based control system, however, has a high level of integration with IQAN controllers for a user-friendly experience. By utilizing this enhanced gateway, our Mobile IoT solution connects data from off-road equipment to a secure Parker cloud and then presents information through an easy to configure interface that delivers advanced insights and data-driven value. These insights have the potential of helping users avoid unplanned downtime events through continuous monitoring with the use of alarms or analytical models.
So, whether you are connecting legacy devices or new devices to your IoT ecosystem, an IoT gateway does have a very important role to play when connecting data to the cloud.
