  • Patent number: 7448603
    Abstract: A catalytic hydrocracking reactor vessel includes enhanced components for the conversion of a hydrogen gas and fossil fuel feedstream to light liquid hydrocarbons. The reactor vessel comprises one or more of a reactor cup riser with a helical cyclonic separator conduit for separating a liquid and vapor product stream to provide an essentially vapor-free liquid recycle stream; a grid plate bubble cap with wall housing having serrated edges for producing small hydrogen bubbles of increased total surface area of bubbles at lower pressure drop; a feedstream inlet pipe sparger containing rows of downward directed slots for even distribution of the feedstream across the cross-sectional area of the reactor and providing free drain of solid particles from the sparger; and optionally a liquid recycle inlet distributor containing vertically curved plates for creating a whirling motion in the liquid recycle stream for better mixing with the feedstream with minimal solids settling.

  • Patent number: 5963010
    Abstract: A battery controller for controlling at least two batteries of different kinds, includes a kind-of-battery detection unit for detecting a kind of battery, and a battery switching unit in which a switching voltage, a suspended mode shift voltage and a termination voltage having different values in accordance with the kind of the battery detected by the kind-of-battery detector are previously set to compare an output voltage of a battery being discharged with the previously set switching voltage, suspended mode shift voltage and termination voltage so that switching of the battery being discharged, stopping of operation of an apparatus being supplied with electric power by the battery being discharged or stopping of supply of electric power by the battery being discharged is performed.
