Abstract

A contactor/filter arrangement for removing particulate contaminants from a gaseous stream is described. The filter includes a housing having a substantially vertically oriented granular material retention member with upstream and downstream faces, a substantially vertically oriented microporous gas filter element, wherein the retention member and the filter element are spaced apart to provide a zone for the passage of granular material therethrough. A gaseous stream containing particulate contaminants passes through the gas inlet means as well as through the upstream face of the granular material retention member, passing through the retention member, the body of granular material, the microporous gas filter element, exiting out of the gas outlet means. A cover screen isolates the filter element from contact with the moving granular bed. In one embodiment, the granular material is comprised of porous alumina impregnated with CuO, with the cover screen cleaned by the action of the moving granular material as well as by backflow pressure pulses. 6 figs.

Centrifugal contactor modified for end stage opertion in a multistage system

Patent Jubin, R.T.

This patent describes a cascade formed of centrifugal contactors useful for countercurrent solvent extraction processes such as utilizable for the reprocessing of nuclear reactor fuels is modified to permit operation in the event one or both end stages of the cascade become inoperative. Weir assemblies are connected to each of the two end stages by suitable conduits for separating liquids discharged from an inoperative end stage based upon the weight of the liquid phases uses in the solvent extraction process. The weir assembly at one end stage is constructed to separate and discharge the heaviest liquid phase while the weirmore »« less
Electric vehicle drive train with contactor protection

Patent Konrad, C.E.; Benson, R.A.

A drive train for an electric vehicle includes a traction battery, a power drive circuit, a main contactor for connecting and disconnecting the traction battery and the power drive circuit, a voltage detector across contacts of the main contactor, and a controller for controlling the main contactor to prevent movement of its contacts to the closed position when the voltage across the contacts exceeds a predetermined threshold, to thereby protect the contacts of the contactor. The power drive circuit includes an electric traction motor and a DC-to-AC inverter with a capacitive input filter. The controller also inhibits the power drivemore »« less
Centrifugal contactor modified for end stage operation in a multistage system

Patent Application Jubin, R.T.

The present invention relates generally to centrifugal contactors in a multistage or cascade system for separating liquids of different weight phases, and more particularly to the modification of the centrifugal contactors functioning as the end stages in the cascade for enabling the cascade to continue operation when an end stage becomes inoperative. This invention was made as a result of work under contract AC05-84OR21400 between Martian Marietta Energy Systems, Inc., and the US Department of Energy. 4 figs.
