ITT Industries Hybrid Posi-Lock Quick Connectors. Slip on, latch, and click, and these connectors mate to standard SAE endforms shaped on metal tubing or injection molded components—eliminating push-on or compression fittings and their time-consuming joints. The latest metal-stem (hybrid) version, initially developed for automotive fuel systems, provides metal-to-metal contact for greater strength. The Posi-Lock slips over the male endform, but only if completely seated for full lock travel will the connector's latch grab the integral ring. Locking gives an audible click and tactile feedback of a secure connection. Pressing on the dual retainer tabs allows the latch to slide open and disconnect.

RFID COUPLER MONITORS PROCESSES
Colder Products Co. Smart Coupling™ Technology. The RFID tag inside the package-coupling inserts of these quick connections can contain history of container contents—to ensure correct sequencing and quality control. Because engineers could not find an off-the-shelf RFID interrogator (read/update) unit small enough (0.8 inch square) to fit easily on the coupling, they developed a one-chip solution, notes Rick Garber, Smart Technology Business Unit manager. His team used a Microchip Technology PIC microcontroller and developed the firmware. The reader features a small interrogation field, out to 1.5 inches, to avoid inadvertantly reading nearby tags. An overmolded, wrap-round antenna within the insert allows signal pickup under any coupler/insert orientation. (www.colder.com) Enter 633
SHORTER, WITH MORE FLOW
Clippard Instrument Laboratory Minimatic® Jumbo Quick Connect fittings. At just under ½-inch diameter, these fittings strike a balance between larger, more cumbersome quick connects and smaller devices with less flow. Although shorter by about ¼ inch than the company's standard Minimatics, these fittings provide more than twice the flow (14 vs. 3 scfm at 100 psi). The reason: A molded Delrin® poppet valve with an O-ring opening/closing against a circumferential surface, rather than a more obstructing tire-type valve. According to Engineering Manager Rich Boutell, the fitting would have to be twice as long to get the same flow with the conventional valve. (www.clippard.com) Enter 634
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
