Abstract: A fuel injector assembly including a member and a seat. The member has a first center along a longitudinal axis. The member has a curved surface and a flat surface. The curved surface has a radius of curvature greater than a width of the member. The flat surface is axially opposed to the curved surface. The seat has a second center disposed on the longitudinal axis. The seat is positioned distal from the flat surface defining a flow path in an open position of the fuel injector assembly and is in confronting relation to the flat surface such that the second center is concentric to the first center forming a sealing interface in a closed position of the fuel injector assembly.

Abstract: A damper is provided. The damper includes a frame having a central opening through which air passes. A plurality of vanes are rotatably mounted within the frame. At least one of the vanes is oriented about a rotational axis that is offset at a non-orthogonal angle with respect to one of a horizontal and vertical axis.

Abstract: A back draft damper includes a rectangular shell having a central opening which air can pass through. A plurality of vanes rotatably mounted in the shell are rotatable between open positions where air can pass through the shell and closed positions where air cannot pass through the shell. The axes the vanes rotate about are slightly offset from vertical.

Abstract: Disclosed are chemochromic nanoparticles that can be used as pigments in paints, dyes, coatings, and inks. Because of the small size of the nanoparticles, there is an increased surface area of the chemochromic material that increases the speed of the response of the chemochromic material. The nanoparticles can also be employed in thin film detectors.

Abstract: A remotely readable hydrogen detector is in the form of a tag or card that can be worn on clothing or mounted on a variety of surfaces and can be monitored from a distance for the presence of hydrogen gas. It includes a hydrogen sensor device, which changes in electrical resistivity in response to being exposed to hydrogen gas, that is incorporated into an electric detector circuit, which detects changes in resistivity of the sensor device, and, when such change in resistivity indicates the presence of some predetermined concentration of hydrogen gas, the electric circuit outputs a signal or state that indicates the presence of hydrogen to a transceiver circuit, which can transmit that information to a remote receiver or interrogator/reader via an antenna in the sensor device.

Abstract: A hydrogen gas leak detector comprises a thin film hydrogen detector on a sheet of conformable substrate material, for example, a plastic cling wrap material or a plastic heat shrink material, that is wrappable around a component from which hydrogen gas might leak or evolve. The thin film hydrogen detector may comprise a thin film hydrogen detecting material, for example, a metal oxide, and a thin film catalyst material. The conformable substrate material can be transparent or translucent.

Abstract: A multiple-layered membrane includes a gas permeable membrane layer, a printable surface layer having at least one aperture extending therethrough, and a non-contiguous adhesive layer coupling at least a portion of a first side surface of the gas permeable membrane layer to at least a portion of the printable surface layer, such that a part of the first side surface of the gas permeable membrane layer is exposed through the aperture in the printable surface layer.

Abstract: A replaceable ink supply comprises an ink container with an internal chamber formed from a plurality of walls. An ink reservoir block can be located within the internal chamber. Further, a channel can be formed in at least one wall of the internal chamber and the channel having an open side exposing a portion of the ink reservoir block.

Abstract: In a router, externally received messages addressed to an active line card are bridged to a protection line card. Each line card in the router is programmed to respond to such externally received messages by directing them to the protection line card associated with the active line card as well as to the active line card. The protection line card is configured with inbound and outbound path tables that are the clones of the inbound and outbound path tables of its corresponding active line card. Bridging is accomplished by revising descriptors stored in a plurality of line cards to indicate an association between an active one of the line cards and its protection line card. Received messages are addressed using the revised descriptors to the active line card and also to its protection line card. Upon failure of an active line card, its physical interface can be disabled once its protection line card has clones of the inbound and outbound path tables and bridging has been set up.

Abstract: A fluid containment structure includes a containment vessel having an interior fluid chamber for fluid containment. A flexible bag is disposed within the containment vessel; the bag is vented to the external atmosphere outside the containment vessel. A spring is coupled to the bag to hold the bag in a coiled state until a back-pressure within the fluid chamber exerts sufficient force to commence uncoiling the bag against the spring pressure, allowing air from the external atmosphere to enter the bag and enlarge an interior bag space which is sealed from the interior fluid chamber.
