Abstract: This invention provides for an apparatus and a method for operation of a cryogenic hydrogen storage system that contains a porous medium configured to adsorb hydrogen. The hydrogen storage and supply system includes a hydrogen source apparatus, a cryosorptive storage apparatus, and a fuel recycle loop. Methods and devices that allow for an energy efficient release of hydrogen from the cryosorptive apparatus are described. At the outset of a fuel release, the cryosorptive hydrogen storage apparatus contains cold, pressurized hydrogen. Release of hydrogen from the storage apparatus is a process that consumes heat, thereby drawing down both the temperature and pressure. Heat can be provided to the cryosorptive storage apparatus by various direct approaches, or through the influx of warm, recycled hydrogen.

Abstract: Disclosed is a refrigerating apparatus using a temperature sensitive expansion valve (46) as an expansion mechanism. In the refrigerating apparatus, a switching valve (7a) is disposed on the upstream side of an evaporator (45). The switching valve (7a) is closed for a while, thereby forcibly placing an outlet side of the evaporator (45) in the superheat state to increase the valve travel of the expansion valve (46). Thereafter, the switching valve (7a) is opened for liquid refrigerant to flow through the evaporator (45) so that a wettish operation is carried out. As a result of such arrangement, refrigerating machine oil that has accumulated in the evaporator (45) is reclaimed and returned to a compression mechanism (2D).

Abstract: An electric fan system has a first electric blower 10, which utilizes a brushless motor, and a second electric blower, which utilizes a brushed motor, for distributing the cooling air to the radiator and the condenser. The system has an electronic engine control unit which activates only the first electric blower when it determines that the cooling water temperature is less than T2, and activates both the first and second electric blowers when it determines that the cooling water temperature is T2 or higher. The water temperature is based on a detection output from a cooling water temperature sensor. Thus, since the electric blower is not activated unless the cooling water temperature becomes T2 or higher, use of the brushed motor is limited and its life is increased.

Abstract: The disclosed apparatus comprises a phase fraction meter and a compliant mandrel deployable within a production pipe, and may further comprise a flow velocity meter. The mandrel allows the determination of the phase fraction for a fluid comprising three phases by providing an additional cross sectional compliance within the conduit, thereby allowing the density of the fluid to be determined. The mandrel also provides a specified blockage through the flow velocity meter, thereby increasing flow velocity through the meter. This allows flow rate measurements in conditions under which flow velocity in the under-restricted cross-sectional area of the pipe would normally be very low. Further, the mandrel can provide a specified restriction in the pipe, i.e., a venturi. By measuring the differential pressure across the venturi and utilizing the measured fluid velocity from the flow velocity meter, the density of the fluid mixture can be calculated.
