Summer break with H&P
It's hard to believe it's June already and we're already into the start of summer. Things tend to slow down a bit in the warmer months for most of us, and I'm sure it's no different for you.
If you do have some down time in the coming months, let Hydraulics and Pneumatics keep you busy. If you're a social media junkie, you can get your fix on my Twitter page, as well as Michael Ference's Publisher page
Also, like and join our Facebook, and LinkedIn groups to stay connnected.
Finally, we're already half-way through the year with our 2011 edition of The World’s Smartest Design Engineer. Don't miss out on a chance to play the game and win some fun prizes!
In the meantime, enjoy this edition of Fluid Power Monthly, which is chock full of web exclusive articles you won't find in print, including an overview of hydraulic hybrid technology, a peek at our October robotics coverage, an introduction to predictive maintenance from Josh Cosford, and more!

Web Exclusive: Advanced hydraulics help the world's refuse collection fleets "go green"
One of the best ways for the refuse collection industry to achieve its “green” goals is to improve the efficiency of its existing fleet of trucks. Every gallon of fuel saved will have an immediate impact on both greenhouse gas generation and oil consumption.
It is a difficult challenge, because refuse trucks have an extremely difficult duty cycle that includes both inherently inefficient short-distance stop-and-go movement, and the periodic need for brief bursts of energy to compact and dump loads. They typically use a lot of fuel, up to 8000 gal each at an average of 32 gal a day for 250 days per year. They also require costly and intensive drivetrain, braking system, and compaction system component maintenance.

Web-first: Active contact flange gives robotic machines a sense of "polish"
Enjoy an early look at our October pneumatics coverage, which will highlight the use of air-driven devices in robotic automation applications, where gripping and turning objects is necessary. But when it comes to soft or flexible objects, robots often have difficulty handling the task, so they are not suitable for the job. Robots just don’t have a sense of feel — until now, with the development of the Active Contact Flange (ACF) from FerRobotics Compliant Robot Technology GmbH, Linz, Austria.

Web guest column: Fluid Power Tips, Issue 3: The hydraulic fortune cookie
What if I told you that you could predict a machine failure before it happened? And what if I told you that you could save time and money from being wasted on preventative maintenance? Don't get me wrong: if your plant takes part in an intelligently implemented preventative maintenance program, then you're steps ahead of your competition. But what if you were changing filters, rebuilding pumps and valves, and replacing oil at the unnecessary expense of time and money?

Differential pressure transmitters
Miniature DP 1002 and 1020 transmitters from Orange Research are low-cost alternatives for many filtration, level, flow and heat exchanger applications. Both models offer transmitters with current or voltage output, rated at 4-20 mA or 0-5 V. They have an accuracy of 10% (5% repeatability), optional 1-in. diameter durable plastic dial cases, and 1/8-in. NPT porting. Model 1002, with a piston sensor, has a DP range of 0-4 to 0-75 psid and maximum line pressure rating of 3000 psig. Model 1020, with a diaphragm sensor, has a DP range of 0-25 in. water to 0-10 psid and a maximum line pressure rating of 1000 psig. If 2% accuracy is needed, standard size DP transmitter models are available.

Pneumatic valve box
Compact VB valve box from Schunk is directly attached to the PGN-plus gripper and helps increase actuation speed by up to 100%. It also reduces compressed air consumption and reduces energy costs. In case of a conventional pneumatic solution, the compressed air of the feeding long air supply line is lost at each cycle. With the valve box, the piston area of the actuator is immediately filled, resulting in reduced air consumption and shorter cycle times. It comes with air and electrical signals through central connections. Using plug and play, it can be easily commissioned at the actuator with gripping force maintenance devices, throttles, or proximity switches. Sizes for the PGN-plus universal grippers are available from 64 to 160.

Higher-rated vane pumps
Vickers 35V series vane pumps from Eaton Corp.'s Hydraulics Group have been tested and qualified to operate at full pressure ratings with good quality, water-glycol hydraulic fluids. Testing certifies that the pumps are qualified to 2500 psi (172 bar) at 1800 rpm with inlet pressure of 0-5 psig, enabling them to perform at higher ratings. A 7.37 in3/rev displacement and pressure-balanced design provides long service life. Low-noise output reduces operator fatigue. Downtime is minimal because they are easily repaired in the field. Double and thru-drive options are available for high/low circuits.

New white papers from HP and Intel:
Realistic User Productivity Comparisons for Upgrade Decision Making
 AutoCAD® users can appreciate the rock-solid dependable performance they demand from HP and Intel® processor-based workstations. The Intel® Core™ and Xeon® processor-based workstation portfolio includes a wide range of machines that fit multiple user segments, from entry, mobile, essential, and digital workbench users.
Return on Innovation: Making Individuals More Productive
The value proposition for equipping technical and creative professionals has drastically changed. The unprecedented combination of economic pressure and technological advancement has rewritten the rules of how to do more with less. Teams may forego new hires or do the same work with fewer staff, yet they can avail themselves to new tools and techniques. The challenge then becomes how to equip these valuable and fewer number of professionals to be more productive and innovative.

See How 3D Printing Helped in the Medical Cure for Club Feet in Children
Sponsored by: Objet
Date: June 16, 2011
Time: 2:00pm ET/11:00am PT
Dr. Mike North, host of the TV program Prototype This, and Miracle Feet, a non-profit organization providing medical treatment for kids in developing countries, used a Connex 3D Printer from Objet Geometries to build prototypes for a new corrective brace to treat children with clubfoot. Rapid prototyping with the Connex 3D Printer played a big role in developing the optimal brace design. There are currently 1 million untreated cases of clubfoot in the world -- 175,000 new cases a year -- with limited affordable solutions.

How to Quantifiably Confirm Cure of Light Cure Adhesives
Sponsored by: Henkel
Date: June 23, 2011
Time: 2:00pm ET/11:00am PT
A major challenge for OEM’s, especially medical device manufacturers using light cure adhesives, is the ability to easily verify an adhesive’s degree of cure, and thus, speed production processes while improving overall quality. Even the most conscientious manufacturer can experience incomplete cure if an inappropriate or degraded light source generates insufficient irradiance to complete cure, or if rapid processing speeds result in insufficient light exposure. While the adhesive may appear solidified, without time consuming offline verification methods involving destructive physical testing or lab analysis, manufacturers have had no method to quickly and conclusively confirm the degree of cure. It is important to have a simple in-line process that can decrease the resources dedicated to cure verification and that can improve overall quality and production rates for manufacturers. Manufacturers require technology that is ideally suited for assembly processes where high quality and low risk of field failure is desired. It is also essential for medical device manufacturers to use adhesives that meet strict ISO-10993 biocompatibility requirements.
