Title: Swivel drive or the like actuated by pressure medium
Inventor: ALTENHAIN AUGUST
IPC: F15B15/08
Filed: 1984-03-05
Abstract: The illustration according to Fig. 1 and Fig. 2 shows a swivel drive in which a reciprocating movement is converted into a rotary movement. A hollow piston 2 according to Fig. 1, accommodated in the cylinder 1, has balls 6 at one end which are mounted in transversely mounted ball races 6a. At the other end, balls 7 are mounted in transversely mounted ball races 7a. A fixed flange 3 with cylindrical extension 4 has semicircular coarse-pitch thread turns 5 in which the balls 6 engage. The rotatable shaft 8 likewise has semicircular coarse-pitch thread turns 9 in which the balls 7 engage. The balls 6 and 7 have side play in the thread turns 5 and 9 so that they can roll trouble-free. The thread turns are constructed in a right-hand helix on the one hand and in a left-hand helix on the other hand. The rotary movements are cumulative due to this arrangement. The swivel drive can be constructed with one or with two shaft butts. In Fig. 2, five ball pairs are arranged distributed uniformly over the periphery. Rigid power transmission is avoided by this arrangement. High efficiency is ensured through the rolling friction. The cylindrical shape offers effective means of fitting. <IMAGE>

Title: Pulse-width controller for single-phase or multi-phase AC machines
Inventor: REINMOLD HEINZ-JOSEF ING GRAD
IPC: B24B17/10
Filed: 1984-03-14
Abstract: The invention relates to a control circuit or regulation circuit for single-phase or multi-phase asynchronous motors, which circuit operates in accordance with the pulse-width modulation method. The control circuit or regulation circuit comprises an amplifier output stage having power transistors or thyristors and a limiting circuit, which is connected in parallel with the motor winding (3), for the induction voltages which occur in the motor winding as a result of the pulses during the pulse-width modulation. The essential part of the limiting circuit is a transistor (25) which is driven by the pulse-width modulator (2) and electrically closes the motor winding in the current pauses. In consequence, the magnetic field of the motor is virtually maintained in the current pauses, and the induction-voltage peaks, which are dangerous for the switching transistors, are greatly reduced. <IMAGE>
