Snap-Tite Series CP74 Coupling. High residual or thermally generated pressure, often found in circuits of construction and utility equipment, can prevent mating of standard quick-connect couplings. The connect-under-pressure (CP) feature of this push-to-connect coupling allows either half to be placed on a hydraulic circuit with pressures up to 3,625 psi (250 bar). Previously, only male fittings could contain the required pop-off valving. To work for the female, a trapped, molded-polymer T-cross-section seal allows only a small volume (0.07 cm3) of high pressure fluid to vent as the seal passes over the flow opening, preventing seal damage or dangerous spillage. Once connected, the coupling half can join with 74 Series or other ISO 16028 mates. (www.snap-tite.com) Enter 588
SAFE AIR VENTING
Parker Tool-Mate PES and PBS Series Exhaust Couplers. Because they are thermoplastic, these couplings are lightweight and won't scratch surfaces, such as auto windows, painted panels, and furniture, if inadvertantly dragged over them during manufacturing. But not being as rigid as metal couplings, engineers had to balance expansion-with-pressure and temperature strength of the material, says Mario Calvo marketing development manager. Easy to use with one hand, the exhaust couplers provide safe venting of downstream air-line pressure before disconnect—preventing hose whip. (www.parker.com/quickcouplings) Enter 589
COUPLING SPEEDS LUBE CHANGE
Aeroquip FD14 Drain Coupling. Changing gallons of truck engine oil can be time consuming, messy work. This coupling speeds the task. But making the short (only ¼ inch longer than an oil pan plug) engine-mounted male coupling and its female oil-drain system attachment fit within a multitude of vehicle subframe structures was imperative, says Ryan Williams, now development engineering supervisor. So the design team got out and under 300 types of trucks to be sure its compact size and one-hand push/pull, connect/disconnect operation, for minimal spillage, would be workable. For drainage by powered systems or gravity, the valve has a complete through hole for full flow, notes Williams. The valve stem is also riveted, creating an O-ring gland and metal back up to contain the ring, as well as prevent the stem from blowing out. (www.aeroquip.com) Enter 590
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
