    摘要： A flow translocator disposed within a conduit for transferring and separating laminar fluid flow during translocation of the fluid core to the outer perimeter of the conduit and the outer perimeter flow to the center of the conduit. The flow translocator includes a disk disposed transverse the length of a conduit and having an outer profile conforming to the inner profile of a conduit to form a sealed fit. Arrays of slots extend about the disk for simultaneously directing the fluid core to the inner profile of a conduit and the outer perimeter flow toward the fluid core. The slots are staggered to maintain separation of the fluid core and the outer perimeter fluid during translocation.

    摘要： Method of operating an autothermal reformer (ATR) to produce a high temperature reformate including preheating steam and air inputs to the ATR with heat from the reformate. The steam is heated by the reformate, and the air is then heated by the steam. There is no direct heat exchange between the reformate and the air. In the heat exchangers effecting the heat transfer, the steam is kept at a higher pressure that both the reformate and the air.

    摘要： A process for controlling the length of a purge and the purge rate of a fuel cell stack at system shut-down so as to provide the desired amount of stack humidity. The membrane humidification is measured at system shut-down by a high frequency resistance sensor that detects membrane humidification and provides the measurement to a controller. The controller controls the compressor that provides cathode input air to the fuel cell stack so that the time of the purge and the flow rate of the purge provide a desired membrane humidity for the next start-up.

    摘要： A cooking utensil with improved heat retention includes an inner pot received within an outer pot and separated in a closely spaced-apart relationship to form a volume or chamber therebetween. The chamber is evacuated and sealed with foil leaves at the upper edges of the inner and outer pot. The vacuum created between the inner and outer pot, along with the minimum of thermal contact between the inner and outer pot, and the reduced radiative heat transfer due to low emissivity coatings on the inner and outer pot, provide for a highly insulated cooking utensil. Any combination of a plurality of mechanisms for selectively disabling and re-enabling the insulating properties of the pot are provided within the chamber. These mechanisms may include: a hydrogen gas producing and reabsorbing device such as a metal hydride, a plurality of metal contacts which can be adjusted to bridge the gap between the inner and outer pot, and a plurality of bimetallic switches which can selectively bridge the gap between the inner and outer pot. In addition, phase change materials with superior heat retention characteristics may be provided within the cooking utensil. Further, automatic and programmable control of the cooking utensil can be provided through a microprocessor and associated hardware for controlling the vacuum disable/enable mechanisms to automatically cook and save food.
