  • Patent number: 7223456
    Abstract: A multi-layered pipe of arbitrary length and cross-section is produced by co-extrusion of a segmented thermoplastic copolyester elastomer (COPE) outer body over the exterior surface of an annular tubular core of CPVC/PVC having a wall thickness, measured in the radial direction, in the range from about 0.95 mm (38 mils) to about 1.375 mm (55 mils). The COPE is cohesively bonded to the annular core coextensively with essentially the entire length of the pipe. Though the COPE is easily degraded in contact with water, and CPVC and blends of CPVC with less than 25% by weight of PVC are typically rigid when extruded as pipe, a laminated pipe of COPE and CPVC/PVC with the specified wall thickness and overall dimensions which in the laminated pipe satisfy an applicable plumbing code (SDR-11 in the U.S.) has essentially the same performance characteristics as commercially available CPVC pipe which is a monolayer and not a laminate.

  • Patent number: 7223479
    Abstract: In certain example embodiments, a multi-layer undercoat may include a layer of or including tin oxide on the glass surface and a layer of silicon nitride thereover. Tin oxide is advantageous in that it is relatively durable, and is a low stress material with excellent adhesion to glass. Moreover, the sputtering rate for tin oxide is several times higher than that of silicon nitride. Thus, problems of high cost (due to slow deposition rate) and durability (due to high compressive stress) can be overcome through the use of tin oxide as a bottom portion of the dual layer overcoat. The coated article may or may not be heat treated in different embodiments of the invention.

The passageways are filled with ion-conducting material and may be surrounded by non-ion conducting material. The membrane may comprise a substrate of non-ion-conducting material that is penetrated by openings, each opening providing a corresponding one of the passageways.

  • Patent number: 7223494
    Abstract: Contact of terminals of a component to be loaded on a device and terminals on the device are avoided, even if the component is similar to, but differs from, a component intended to be loaded on that device. A discriminating tab is provided in the vicinity of the component terminals and a blocking portion is provided in the vicinity of the device terminals. The discriminating tab and blocking portion are relatively positioned to provide concave and convex interference or engagement with each other, either to block connection of the component terminal with the device terminal because of interference if the component is not permitted to be loaded on the device, or to permit connection of the component terminal with the device terminal because of engagement.
