摘要： A clutch assembly capable of providing several predetermined settings, wherein the components which support springs applying torque are not subjected to bending loads. The settings are achieved in that a supporting ring supporting a pressure plate against a clutch housing is provided with radially outwardly extending cams which are offset relative to the center thereof with two rows of apertures being provided in a cylindrical face of the clutch housing which are axially offset and offset relative to the angle of rotation and which correspond to the cams of the supporting ring and within which the cams are engaged.

摘要： A shaft connecting mechanism is provided between a slip-on hub and a power takeoff shaft by means of a control ring which extends around the slip-on hub and which is formed to have a pressure screw extend through a threaded bore therein, the pressure screw engaging against a clamping wedge in the slip-on hub which is formed with a trapezoidal configuration generally conforming with the configuration of an axiallly extending groove formed in the slip-on hub. Blocking members are arranged in radial apertures in the slip-on hub and pockets are formed in the control ring. The pressure screw when angularly aligned with the clamping wedge, places the control ring in the locked position and when the pressure screw and the clamping wedge are angularly unaligned, the blocking members enter the pockets in the control ring.

摘要： In a method for operating an x-ray device, an x-ray beam is generated at a focal spot of a rotary anode that is rotatable around a rotation axis, and the x-ray beam is gated with a slit-shaped diaphragm to produce a fan-shaped x-ray beam, that is moved through an examination region in the manner of a scan. To improve the image resolution, the fan-shaped x-ray beam can be moved over the examination region essentially in the direction of the rotational axis of the rotary anode by tilting the x-ray tube on the focal spot, with the x-ray tube being tilted on the focal spot so that the fan-shaped x-ray beam is always gated from the region of the overall emitted x-ray beam having the highest image resolution or the highest image definition in the movement through the examination region.
