however, they only absorb small amounts of energy, limiting them to slow-speed, small-load, or short-stroke applications Operating with higher loads and speeds demands additional cushioning to avoid damaging the cylinder and machine Engineers generally use air cushions for end-of-stroke damping in these cases Unfortunately, these are not plug-and-play devices Experienced maintenance technicians must adjust the air-cushion valves, and that depends on the cylinder’s operating pressure, speed, and load Subsequent changes to these parameters means the air cushions need to be reset Otherwise, the machine may run slower or face unacceptable impact loads A new type of air cushion automatically adapts to changing conditions, eliminating the headache of manual adjustments It offers the potential to increase productivity and reduce maintenance costs Cushion basics Air cushions are variable-orifice air dashpots As the cylinder cycles, a spud on either side of the piston closes a passage to the main piston chamber This traps air in the cylinder end cap and bleeds it off through a small port conSeptember 22, 2011 trolled by a needle valve The cylinder traps a fixed volume of air each cycle But because air is compressible, the load, velocity, and pressure in the cylinder all affect air-cushion performance For any given set of conditions, there is generally only a small window of needle-valve adjustments that provide acceptable cushioning Closing the needle valve too far results in high initial reaction forces, which slow the load too quickly It can also cause end-of-stroke bounce: the piston oscillates as it decelerates, causing vibration and extending cycle time Open the needle valve too far, however, and the trapped air does not generate sufficient back pressure The load reaches the end of stroke too quickly and the piston hits the end cap And as mentioned above, once the needle valve is properly set, any change in weight, pressure, or velocity affects cushion reaction and means the valve must be readjusted Self-adjusting cushions Recently developed self-adjusting cushions eliminate the need for manual adjustment In principle, they work the same way as conventional cushions, except the cushioning air exhausts through notches in the cushioning piston, not past an adjustable needle valve The geometry of these notches is critical LongitudiSeptember 22, 2011 64 off accidental fires 50 Heading in solar arrays Fighting a PV panel fire is hazardous enough without having to stand in water next to a 600-Vdc power source that can’t be turned off 56 pneumatics technology guide guidelines for SeleCting CylindeRS pneumatic cylinders come in thousands of versions here are some tips for choosing the best one for the job Guidelines for selecting cylinders Pneumatic cylinders come in thousands of versions Here are some tips for choosing the best one for the job Authored by: Sheila Campbell Product Manager - Actuators Norgren Inc Littleton, Colo Edited by Kenneth J Korane ken.korane@penton.com Key points: • Pneumatic cylinders come in many basic versions • All cylinders can be tweaked to better fit an application • Custom designs can perform better and save money when standard cylinders don’t fit the job 64 Cylinder cushions adapt on the fly Resources: Norgren Inc., www.norgren.com RS# 621 Clean, compact, durable, and fast-acting air cylinders are workhorses on packaging machinery 56 Self-adjusting air cushions let machines run smoother and faster mACHINe Design.com ion via our Request free informat Web site at Reader Service esign.com/rsc www.machined September 22, 2011 56 Access our Reader Service Web site to quickly find and request information on the products and services found in the pages of MACHINE DESIGN www.machinedesign.com/rsc MACHINE Design.com SEPTEMBER 22, 2011 mACHINe Design.com 65 Directional Control • Solenoid valves • Manifolds Air Preparation • • • • • Filters Regulators Lubricators Filter/regulator combos Relief valves Check around!

The Pack Expo trade show is about to kick off and is notable because it caters to the packaging industry The packaging industry, in turn, largely revolves around the packaging of food So it might be appropriate to examine the recent trend toward hand-wringing over “food miles.” The idea is that the longer food travels before it hits your plate, the more energy dissipated and greenhouse gases generated At least according to popular mythology The truth of the matter is that most energy and greenhouse gases associated with food go into its production, not its transportation And that goes equally for food bought at the local farmers’ market as well as for that picked from grocery-store shelves The issue of food miles has been thoroughly investigated by two environmental engineers at Carnegie Mellon University in the U S and by the Dept for Environment, Food and Rural Affairs in the U K CMU researchers Christopher Weber and H Scott Matthews found that the food-production phase contributed 83% of the average U S household’s annual carbon footprint for food consumption Transportation as a whole accounted for only 11% of greenhouse-gas emissions associated with food And final delivery from producer to retail contributes only 4% of that 11% It also emerges that transport by ship, rail, and air freight over long distances is efficient compared with trucking food a comparatively short distance to its final destination The trucking phase is responsible for 71% of the total greenhouse gases generated while transporting food Wholesaling and retailing operations accounted for just 5% of overall emissions CMU researchers as well found that globalization has increased the distance food travels by around 25% since 1997 But this has boosted greenhouse-gas emissions associated with transport by a mere 5%, simply because ocean shipping is far less energy intensive than overland trucking In the U K., DEFRA examined the “food miles” question partly to see whether a “buy-local” movement in that country made any sense DEFRA uncovered percentages similar to those of the CMU research, and also discovered that “buying local” could lead to more greenhouse-gas emissions rather than less The reason is that a lot of produce in the U K must be grown in greenhouses rather than in open fields The energy debt of a greenhouse is a dealkiller, greenhouse gas-wise The situation isn’t much better for produce grown in U K fields that must be put in cold storage until it is eventually consumed U K residents generate fewer greenhouse gases shipping fresh apples in from New Zealand than putting British apples in a cooler And when it comes to milk, U K dairy farmers use twice as much energy to produce a metric ton of milk solids than New Zealand farmers, says DEFRA The lesson from all this is that food should be grown where it is most economically virtuous to so And the packaging industry needn’t worry about “buy-local” movements

94 MACHINE Design.com SEPTEMBER 22, 2011 A survey by Pew Research Center’s Internet & American Life Project has shown that approximately 13% of people stage fake calls on their cell phones to avoid speaking to people around them For those 18 to 29-yearsold, that number jumps up to 30%, while dipping down to 6% for those between 50 and 64 In the 30 to 49 age range, 11% are regular fakers Smartphone owners bring the average up a bit with one in five of admitting to making phony calls The survey of 2,277 Americans revealed that a whopping 83% owned some kind of mobile phone Additional findings include: • Forty-two percent indicated that they use their mobile phones for entertainment • Mobile phones can also be a lifesaver, with 40% saying they’d found it useful in an emergency • Most use their mobiles to send text messages • The younger you are, the more likely it is you’ll own one, with 94% of 18 to 29-year olds using cells • Seventy-three percent use their phones to send

When your company mission is “Motion Without Limits,” what better way to accomplish this than to sponsor one of your employees in the Oregon Bike MS fund raiser Bishop-Wisecarver Corp., San Francisco, sponsored employee and cyclist Chris Crawford in the two-day event, which benefits more than 7,200 people with multiple sclerosis that the National MS Society, Oregon Chapter serves each year “I have friends and loved ones affected by MS, and so many of our employees As a company based on motion without limits, it’s only befitting of us to get involved,” said Pamela Kan, president of Bishop-Wisecarver, adding she has been a personal sponsor of Crawford for years “I am very honored to have helped Chris support this cause He is a true inspiration.” Bishop-Wisecarver is a leader in guided motion technology and the manufacturer of the original DualVee guide wheel Crawford rides in support of his sister, Bonnie Iglesias, who has been fighting MS for years As part of Bishop-Wisecarver’s corporate involvement, the brother and sister team were asked to share their story on camera Crawford and his sister have raised $250,000 since their first bike ride in 2000, and he credits this success to the personal stories they share publicly with their supporters After the bike ride this year, he wrote a letter of his personal experiences to all of his supporters The letter is published online on Bishop-Wisecarver’s company blog To watch video coverage of the event and interviews with Crawford, check out the BishopWisecarver YouTube channel For live news and
