摘要:
A fluid filter mount is affixed to the top closure wall of a fluid reservoir, such as for a hydraulic power unit, wherein the housing for the filter mounting is positioned below the top closure of the reservoir with the fluid inlet and fluid outlets also being provided in the housing below the top closure of the reservoir. The filter mount housing has an upwardly extending portion which extends into an opening in the top closure of the reservoir for exposure thereabove and is adapted to receive a canister type fluid filter thereon in sealed engagement with the filter in an upright position such that the fluid inlet and outlet are registered in communication with the filter for flow-through filtering. An upwardly open annular channel is provided on this filter mount such that it is positioned radially outward from the area wherein the filter canister is in sealed engagement with the filter mount and this annular channel is provided with at least one vertical through opening for gravitational flow of hydraulic fluid which will flow into the channel from a filter canister as it is being removed for exchange, and the fluid is permitted to thereby free flow back into the hydraulic fluid reservoir preventing any messy oil spills onto the hydraulic power unit and additionally providing a flush mount attractive mounting of the filter canister on top of the reservoir.

The invention is an electrically insulative aqueous polymer composition. The composition includes a thermoplastic acrylic-styrene copolymer emulsion, a wetting agent, water, a surfactant, and a ductility agent. The invention also includes methods of using the electrically insulative composition, as well as methods of using a related electrically conductive aqueous polymeric vehicular emulsion composition.
摘要:
Fuel cell stacks comprising stacked separator/membrane electrode assembly fuel cells in which the separators comprise a series of thin sheet platelets, having individually configured serpentine micro-channel reactant gas humidification active areas and cooling fields therein. The individual platelets are stacked with coordinate features aligned in contact with adjacent platelets and bonded to form a monolithic separator. Post-bonding processing includes passivation, such as nitriding. Preferred platelet material is 4-25 mil Ti, in which the features, serpentine channels, tabs, lands, vias, manifolds and holes, are formed by chemical and laser etching, cutting, pressing or embossing, with combinations of depth and through etching preferred. The platelet manufacturing process is continuous and fast. By employing CAD based platelet design and photolithography, rapid change in feature design can accommodate a wide range of thermal management and humidification techniques. One hundred H.sub.2 --O.sub.2 /PEM fuel cell stacks of this IFMT platelet design will exhibit outputs on the order of 0.75 kW/kg, some 3-6 times greater than the current graphite plate PEM stacks.
摘要:
A remote surveillance system (the system) of the present invention is designed to have a long independent operation, portability, and wireless transmission of digital data from any location worldwide. The system includes a hybrid power element having novel hydrogen storage and generation device, light weight polymer electrolyte membrane (PEM) fuel cell, and the low power and low weight electronics. The system also includes multiple day/night cameras, motion detector, global positioning system (GPS), and wireless module. The system is packed in a back pack case and is easily carried between multiple locations due to low weight and compacts size.
