Abstract: In an operating table system for the computer tomography assisted performance of operations on patients, including an operating table 10 with a subframe 14 and a patient support surface 12 releasably connected with the subframe, the patient support surface means 12 has a frame 16 connected with the subframe 14 and an x-ray permeable patient support plate 20 longitudinally slidably carried in the frame 16, with a support frame 44 intended for the reception of the support plate in a computer tomography system 40 having coupled with it a coupling station 46 for the transfer of the support plate from the operating table 10 to the support frame 44 and vice versa.

Abstract: A sensor bearing for the detection of rotational speed and angle torsion of a shaft or hub or axle comprises a bearing having an inner raceway, an outer raceway, and a cage situated between the inner raceway and the outer raceway. A plurality of balls is rotated around halfway between the inner raceway and the outer raceway at a speed proportional to the rotational speed of the shaft or hub or axle. Each of the balls contains a magnet integral thereto. The sensor bearing also comprises a plurality of hall effect sensors spaced along the inner periphery of the outer raceway and at a distance proportional to the spacing of the balls along the raceway such that, as each ball passes one of the Hall effect sensors, an electrical signal is generated.

Abstract: A motor spindle for magnetic disc storage drives includes an outer rotor connected to an inner shaft which is rotatably mounted by an integrated bearing including rolling elements, such as balls, which run in inner and outer races, the outer race being formed in the stator bushing and the inner race being formed in the shaft.

Abstract: A magnetic fluid seal provided in a sealing gap defined between an inner surface of an outer rotor and the outer periphery of a disc-shaped magnet includes magnetic liquid situated in the sealing gap and the improvement wherein the inner surface of the outer rotor is inclined so that in a cross-section through a plane containing the axis of rotation of the rotor, the inner surface forms an angle with the axis of rotation of the rotor whereby retention of the magnetic liquid in the sealing gap is facilitated by the reaction forces to the centrifugal forces acting on the magnetic liquid during operation.
