Abstract: Pressure swing adsorption (PSA) assemblies with temperature-based breakthrough detection systems, as well as to hydrogen-generation assemblies and/or fuel cell systems containing the same, and to methods of operating the same. The detection systems are adapted to detect a measured temperature associated with adsorbent in an adsorbent bed of a PSA assembly and to control the operation of at least the PSA assembly responsive at least in part thereto, such as responsive to the relationship between the measured temperature and at least one reference temperature. The reference temperature may include a stored value, a previously measured temperature and/or a temperature measured elsewhere in the PSA assembly. In some embodiments, the reference temperature is associated with adsorbent downstream from the adsorbent from which the measured temperature is detected.

Abstract: The present invention is moisture activated removable facial camouflage tattoo carrier sheet for disguising a human face. The tattoo carrier sheet comprises a water permeable transfer sheet, at least one temporary and removable moisture activated facial camouflage tattoo lo disposed on the water permeable transfer sheet. A protective release sheet is removably disposed on the water permeable transfer sheet over the facial camouflage tattoo as temporary protective covering for the facial camouflage tattoo.

Abstract: The present invention provide compositions and methods for preparing and applying moisture activated removable camouflage tattoos for disguising exposed skin or inanimate surface. The tattoo carrier sheet comprises a water permeable transfer sheet, at least one temporary and removable moisture activated facial camouflage tattoo disposed on the water permeable transfer sheet. A protective release sheet is removably disposed on the water permeable transfer sheet over the facial camouflage tattoo as temporary protective covering for the facial camouflage tattoo. The method of application comprises removing the protective release sheet, exposing the water permeable transfer sheet to water, contacting the camouflage tattoo with a surface, and removing the water saturated water permeable transfer sheet thereby depositing the camouflage tattoo on the surface.

Abstract: A semiconductor substrate processing system and method of using a stable heating source with a large thermal mass relative to conventional lamp heating systems. The system dimensions and processing parameters are selected to provide a substantial heat flux to the substrate while reducing the potential of heat loss to the surrounding environment, particularly from the edges of the heat source and substrate. Aspects of the present invention include a dual resistive heater system comprising a base or primary heater, surrounded by a peripheral or edge heater. The impedance of the edge heater may be substantially matched to that of the primary heater such that a single power supply may be used to supply power to both heaters. Both resistive heaters deliver heat to a heated block, and the heaters and heated block are substantially enclosed within an insulated cavity. The walls of the insulated cavity may include multiple layers of insulation, and these layers may be substantially concentrically arranged.

Abstract: A utility tether for a life raft, includes a tether having a plurality of links for securing a person to the tether. The tether is stored outside the canister of the inflatable raft to be accessible before deployment of the life raft. The tether includes means for linking persons on board a vessel in distress to the tether before the life raft is deployed and subsequently inflated. The links comprise adjustable loops that are cinched about a wrist or chest. Persons entering the water are thus tied to the life raft, which aids the secured persons in reaching the life raft to board even in rough water or winds. The tether alternatively includes flotation devices and lighting devices attached in conjunction with the links. The tether also includes a control line for manipulating a raft stabilizing bag to control for the effects of current and wind on the raft.

Abstract: A self-bailing stabilized life raft includes a bailing chamber located between a stabilization chamber and a flotation platform. Water received from a flexible floor of the flotation platform is exhausted from the bailing chamber in response to wave and/or occupant interaction with the life raft. A raft inflation apparatus includes a pump chamber actuated by raft motion.

Abstract: A stabilized life raft utilizing a fluid filled depending buoy chamber for overall stabilization and including as improved features thereon a peripheral skirt chamber which fills with the raft supporting fluid upon deployment of the raft and serves as a temporary stabilizer while the buoy chamber becomes filled. The buoy chamber includes baffles to impede the flow of the stabilizing fluid from one portion of the chamber to another in the event of a sudden weight shift within the raft. An improved valve permits a more rapid inward flow of fluid upon deployment of the raft and yet prevents outward flow in instances where the buoyant raft is suddenly thrust upwardly by elements such as waves. The raft, because of the particular placement of the various structural elements in conjunction with the placement of the survival gear and inflation system, is automatically self-righting.
