Abstract: An integrated CT scanner gantry assembly is provided wherein an open bore rotor is supported by a bearing assembly on an open bore stator. An x-ray assembly is mounted on the rotor and supplied with high voltage power during continuous rotation about the stator through use of a slip ring assembly which is mounted between the rotor and stator. The inside surface of the stator which faces a patient generally lies along the surface of a truncated cone to permit substantial tilting of the stator. Moreover, the stator and rotor have a cross section formed as a series of separated yet aligned steps to form two isolated cavities therebetween, one of the cavities housing the cathode of the slip ring and the other of the cavities housing the anode of the slip ring. The cavities can be filled with a gas or liquid high voltage insulating fluid and can be readily sealed to prevent leakage of said fluid. An x-ray assembly bracket is removably attachable to the rotor to support an x-ray source and x-ray optics in order to permit the x-ray source and x-ray optics to be assembled and aligned on the bracket at a location remote from the rotor and stator. The overlapping positions of the separated yet aligned steps relative to the x-ray source and optics assembly bracket reduces the cross-sectional area and overall gantry volume thereby providing comfortable patient access for whole body CT scanning.

Abstract: An improvement in dynamo electric machines is disclosed in which the brush holder is electrically isolated from the brush pigtail terminal junction. The member which supports the junction connecting the brush pigtail and the lead from the stator includes an insulator which electrically isolates the junction from the brush holder. The insulator eliminates the relatively low impedance electrical path between the brush terminal and the commutator through the brush holder, preventing damaging arcing between the commutator and the brush holders.

Abstract: A power terminal includes a terminal beam having a mating surface. A protective thermal coupler bridge is positioned adjacent the terminal beam having a bridge conductor, an insulating substrate and a bridge pad. The bridge pad has a mating surface. A variable resistive member is electrically coupled between the terminal beam and the bridge conductor to provide a shunt so that arcing does not occur when the power terminal is disconnected from the mating power terminal. The mating surface of the terminal beam is separable before the mating surface of the bridge pad is disconnected so that the resistance in the variable resistive member increases after disconnection of the main power terminal from the mating power terminal and prior to disconnection of the bridge pad from the mating power terminal to shunt the current through the bridge conductor and the variable resistive member during unmating.

Abstract: A device (i.e., a slip-ring or a homopolar motor/generator) (40, 50, 80) is adapted to provide electrical contact between a stator and a rotor (41, 83), and includes: a current-carrying brush-spring (31, 84) mounted on the stator, and having two opposite surfaces; a fibrous brush assembly (35, 69) mounted on the conductor, the brush assembly having a bundle of fibers (36, 71) arranged such that the tips of the fibers will engage the rotor for transferring electrical current between the stator and rotor; a ribbon (33, 85) of superconducting material mounted on each opposite surface of the current-carrying brush-spring and communicating with the stator and the brush assembly; and another ribbon (29, 86) of superconducting material mounted on the rotor. The device is submerged in a cryogenic fluid at a temperature below the transition temperatures of the superconducting materials such that the electrical resistivity of the device will be reduced and the current-transfer capability of the device will be increased.
