摘要:
A system for controlling an automated video cassette library apparatus is provided which is actuated in response to command signals originated by an individual at a location remote from such apparatus to transfer a select video cassette in a horizontal plane from a cassette shelf to a cassette player each of which is located in a compact housing. The apparatus is then ready for use by another individual who may select another video cassette for playing upon another video player each of which is located in the same housing. The cassette player plays the video cassette and communicates the recorded program to the individual's television set. Upon completion of each play, the video cassette is rewound and automatically transferred from the cassette player to the cassette shelf.

A cryogenic submerged multi-stage pump assembly includes a vertically oriented pump shaft. A permanent magnet electrical motor includes a rotor attached to the pump shaft and a stator disposed about the rotor. A first-stage impeller assembly includes a first impeller attached to the pump shaft, the first impeller configured to move a cryogenic fluid from a first impeller inlet to a first impeller outlet when the pump shaft is rotated by the electric motor. A second-stage impeller assembly includes a second impeller attached to the pump shaft, the second impeller configured to move the cryogenic fluid from a first impeller housing to a second impeller inlet and then to a second impeller outlet when the pump shaft is rotated by the electric motor. The first and a second impeller housing are disposed about the first and second impellers and configured to channel the cryogenic fluid.
摘要:
A support system for preventing the displacement of a pendantly suspended body, such as a submersible, turbine or sump pumping apparatus, and comprising one or more fixed frame structures which surround the body below its point of suspensing and each of which has a plurality of abutment members disposed thereon about the periphery of the body, that cooperatingly engage a similar number of abutment plates on the body to hold it against lateral or pendulous displacement. When the body is inserted through the frame structures, it is oriented such that the abutment plates on its periphery pass into the interstices between the abutment members on the frame structures. Before the upper end of the body is fastened to its suspension mounting the body is rotated so that the outer edges of the abutment plates engage the outer edges of respective abutment members with a small clearance fit securing the body against movement. The ends of the outer edges of the abutment plates are rounded to facilitate smooth sliding engagement of the abutting surfaces.
