Title: DC motor without a commutator
Inventor: MUELLER ROLF DR ING
IPC: H02K29/08
Filed: 1984-09-03
Abstract: A three-phase DC motor without a commutator having a permanent-magnetic rotor-magnet arrangement (which has at least two pairs of poles) and having a star-connected, three-strand stator winding whose winding strands are arranged in a non-overlapping manner in slots of a slotted stator and whose currents are controlled, via at least three semiconductor elements, by means of at least three position-signalling sensors which are sensitive to magnetic fields and, for their part, are controlled by the rotor-magnet arrangement. The position-signalling sensors are arranged distributed in the stator circumferential direction with respect to the stator winding strands in such a manner that in each case that position-signalling sensor which causes the commutation of the winding current from one winding strand to another is fitted in the stator region in which there is no coil through which current flows either before or after the commutation process. <IMAGE>

IPC: G03B7/16
Filed: 1985-05-24
Abstract: An endoscope camera ensures an accurate level of exposure at all times, even when the level of illumination is increased or rises after operating or actuating the release key of the camera. The light-increasing unit (10) is operated by the EP contacts (50) or the M contacts (40) of the camera. A time-delay circuit (52) causes a memory to store a then current exposure value of a prescribed time delay after operation of the light increasing units, in particular after the light output signal has been stabilised at a raised level. The shutter is operated in accordance with the exposure value thus stored. <IMAGE>

Title: Explosion door
Inventor: ALTMAYER GERHARD DIPL ING
IPC: A62C3/04
Filed: 1986-01-28
Abstract: An explosion door of a coal-dust container is provided with a catching device. The catching device holds the explosion door open after an explosion and makes possible a reverse flow, which takes place immediately after venting and re-compensates the subatmospheric pressure in the container which arises owing to the drop in temperature. The catching device is then released again by a control means. In order to ensure the functioning of the catching device, shock absorption is provided. The invention proposes a permanently deformable shock absorber which is to be exchanged after it has been subjected to loading. Said shock absorber is capable of breaking down a high degree of kinetic energy in an extremely short period of time. <IMAGE>

Title: Ball-type constant-velocity joint
Inventor: WELSCHOF HANS-HEINRICH DIPL IN
IPC: F16D3/223
Filed: 1986-06-11
Abstract: The invention relates to ball-type constant-velocity joints in which the track ends of the inner joint body and of the outer joint body, which ends lie to the outside of the ball tracks subjected to load when the joint bends, deviate from one another asymmetrically in longitudinal section in relation to the ball centres with the joint unbent, thereby making it possible to adopt the preferred processes for the production of the ball tracks, namely forming for the ball tracks of one joint body, these ball tracks, including the track ends, being free from undercuts in longitudinal section, and machining for the ball tracks in the other joint body, these ball tracks, including the track ends, having a continuous curvature in longitudinal section and, in particular, being circular arc-shaped, the machining process being, especially, grinding while swivelling the joint body. This makes it possible to achieve high production accuracy in series production even with large tolerances in the production of the formed ball tracks of one joint body, by individual grinding of the ball tracks of the second joint body. <IMAGE>

Title: Method and device for range finding by processing optical pulse signals
Inventor: GAECHTER BERNHARD DIPL PHYS DR
IPC: G01S7/486
Filed: 1986-06-16
Abstract: A method for range finding between a transmitter/receiver and a target, using optical pulse signals, is described which manages with extremely low transmitted pulse energy and, nevertheless, exhibits a much higher sensitivity or noise suppression compared with conventional methods. For this purpose, optical pulse bursts with a pulse rate in the range between approximately 10 and approximately 150 kHz are directed towards the target. The reflected and received signal sequence is sampled and digitised with a sampling frequency dependent on the transmitted pulse rate. The samples obtained for the corresponding value for each individual transmitted pulse are continuously added together at the rate of the sampling frequency. The range information is derived from the resultant signal. The received signal sequence is preferably scanned at a sampling frequency in the nanosecond range. The signals are processed, for example, in a parallel adder (7), a continuous parallel addition of the digitised received signals with the sum signal of the adder being effected for each transmitted pulse. In particular, the output of the adder (7) can be connected to the input for the second summand via a shift register (9). Alternatively, a microprocessor operating in the nanosecond range can also be provided as processor, in which the function of the [lacuna] related to the transmitted pulse ...

IPC: F04D15/02
Filed: 1986-07-23
Abstract: The object of the invention is a control device for submersible motor-driven pumps, where the operating condition of the pump is controlled by electrical sensors that are influenced by the level of the liquid. Several sensors are used, which because of different heights and distances carry out a conductivity measurement on the surrounding liquid. Thus both the presence of a medium to be pumped out, its height and also, depending upon the sensor type, its composition can be detected and displayed and corresponding control commands can be carried out by a circuit.
