Title: Rotary piston I.C. engine - has circular stator with radial vanes and eccentric rotor with output shaft
IPC: F02B75/02
Filed: 1974-05-09
Abstract: The rotating piston engine has a circular stator chamber within which rotates a circular rotor type piston about its eccentric axis, and can work as a two or four stroke engine. The stator chamber has slots for radial vanes whose ends are in contact with the rim of the rotating piston. The eccentric rotor diameter is such that the distance between the centre of the eccentric shaft and the remotest point of the rotor rim is slightly smaller than the radius of the chamber. The distance from the shaft centre of the nearest point of the rotor rim is not greater than half of the chamber radius. Hence the rotor does not contact the chamber walls. The radial vanes are constantly in contact with the rotor rim and variable volume pockets are generated on rotating between the vanes and the chamber and rotor walls.

Patent FR-2290781-A1 (FR)
IPC: H02P23/08
Filed: 1975-11-05
Abstract: In the case of torque control of asynchronous machines, the stator rotating-field frequency (f1), which is produced, for example, via a converter, is derived from the mechanical rotation-speed frequency (f) and from the slip frequency (f2) associated with the predetermined torque and is used for controlling the converter or the like. Rapid torque changes can thus not be coped with directly. In order to solve this problem, the supply voltage amplitude (U1) and the stator rotating-field frequency (f1) are formed, in the case of the control circuit arrangement, from the predetermined slip frequency (f2) and the mechanical rotation-speed frequency (f), with the aid of interconnected computing units and of machine characteristic variables which are preset therein, in such a manner that, in the event of rapid changes in the predetermined slip frequency (f2), the amplitude and phase of the rotor field do not change, or change only slightly, and the frequency of the rotor field with respect to the rotor remains equal to the predetermined slip frequency (f2). The ratio of a predetermined slip frequency value to the pull-out slip frequency (fk2) is used, in particular, in this case as the reference variable for the slip frequency, and is modified in accordance with the actual value of the pull-out slip frequency (fk2act). A particular advantage is the capability to use the same circuit arrangement for requirements of different stringency levels with respect to the dynamic operating characteristics.
