Title: Electrical measuring device for the rotor temperature of electric machines
Inventor: GUENTNER HERWIG DR ING
IPC: G01R31/34
Filed: 1981-04-03
Abstract: An inductive ironless transformer arrangement (7, 8) forms together with its stationary ring coil (8) a part of the resonant circuit of a freely oscillating oscillator (9) which is fed from a stationary DC supply (11). The oscillator (9) is loaded by a rotating load circuit (6), which is periodically switched with a temperature-dependent pulse duty factor, and varies its power consumption and its oscillation frequency in a pulse-width-modulated fashion. The measuring signals derived from its variation in power consumption by means of a device (10) are proportional to the rotor temperature. The cyclical switching of the load circuit (6) is performed as a function of the signal of a sensor (1) and of the output pulse of a low-frequency pulse generator (3) via a comparator (4). The frequency of the pulse generator is substantially lower than the oscillation frequency of the oscillator. <IMAGE>

Patent DE-3205564-A1 (DE)
Title: Silo for dry gypsum and other dry mortars
Inventor: DIETTERLE WILHELM
IPC: B65D88/30
Filed: 1982-02-17
Abstract: The silo has a container with a circular-cylindrical middle part, a funnel-shaped lower part and a dome-shaped upper part. A bottom frame is connected firmly to the container. The silo, whilst having good emptying properties, a large capacity and low production costs, is to be transportable horizontally on a heavy-goods vehicle used as universally as possible and having a loading device and is to be erectable and loadable in the filled state by the loading device of this heavy-goods vehicle, but without the fear of external scraping damage and corrosion damage to the container of the silo. The bottom frame consequently has a frame foot, and there project at right angles from a straight portion of the frame foot two mutually parallel frame legs which lead externally past a tangential plane extending along the generatrix of the circular-cylindrical middle part of the container and which are intended for sliding on rollers of the heavy-goods vehicle, the frame legs being connected to the circular-cylindrical middle part of the container by means of spacers. This allows the use of a simpler loading device which does not prevent the heavy-goods vehicle from being employed in the meantime as a platform vehicle.

Title: Appliance for games and sports
Inventor: HINDERER GOTTHILF
IPC: A63B60/00
Filed: 1982-05-08
Abstract: The invention extends to an appliance for games and sports which consists of a preferably spherical sling-ball and a handle connected thereto by a multi-part telescopic tube and capable of limited movement. The most essential difference in the further development, according to the invention, of a previously known appliance of this type originating from the same applicant resides in the fact that an elastic restoring device, preferably accommodated in the interior of the telescopic tube, is arranged between the sling-ball and the handle, as a result of which reliable recovery of the basic position has been achieved with the telescopic tube retracted after each slinging operation, irrespective of the direction of slinging. Various advantageous design possibilities have been indicated for the creation of the restoring device. The creation, based on the size and shape of the sling-ball, of an additional appliance to be handled by a second person for the purpose of pursuing a novel and completely non-hazardous type of competitive sport forms a further feature of the invention.

Patent DE-3217448-A1 (DE)
Title: Internal gear drive
Inventor: KLETZIN PETER DR ING
IPC: B21B31/26
Filed: 1982-05-08
Abstract: The invention relates to an internal gear drive for spindleless roll stands having a large range of adjustment of the roll shafts. The aim of the invention is to improve the operating safety of the roll stands and the use of hard metal rolls, and also to avoid the mirror image arrangement of the internal toothed wheels. The object of the invention is to provide an internal gear drive which compensates for disturbances of meshing of the gears and makes possible the use of the same gear cassettes and roll cassettes because of right-hand or left-hand servicing of machines arranged in mirror image fashion. Features of the invention are that the axes of the eccentric bushings and the axes of the crown shafts are arranged in a plane which intersects the gear cassette and the roll cassette, the axes of the eccentric bushings being offset by a correction amount from the alignment of the axes of the crown shafts, and the eccentric dislocation of the roll shafts in the eccentric bushings being of a different magnitude in contrast to the theoretical axial spacing between the pinions and the internal toothed wheels. Use of the invention in the combination of internal and external toothed wheels.   <IMAGE>
