Title: Friction clutch and brake with automatic adjustment for wear
Inventor: KREISL JOACHIM DIPL ING
IPC: F16D65/56
Filed: 1982-12-03
Abstract: The invention relates to a friction clutch and brake which can be operated by a pressure medium and has automatic adjustment for wear and is intended, in particular, for mechanical presses and shears. The invention is intended largely to eliminate the relatively large amount of manual work involved in the readjustment of the clutch and brake which is necessary due to the wearing of the friction pads (4) and thereby to reduce the machine stoppage times. The object on which the invention is based is therefore to compensate the wear of the friction pads (4) of the clutch or brake by an automatic adjustment of the friction discs (7). According to the invention, this is achieved by virtue of the fact that a compact actuating unit consisting of friction disc (7), clutch or brake cylinder (5) and clutch or brake piston (6) is mounted in the clutch or brake housing in a manner which prevents rotation but allows axial displacement by means of a central threaded ring (9), and that, arranged on the clutch or brake cylinder (5), is a signal transmitter (10) which detects the exceeding of the permissible piston stroke and the output signals of which control a drive operatively connected to the central threaded ring (9). <IMAGE>

Patent DE-3300176-A1 (DE)
Title: Spring motor in three versions with stepless, hydraulic power transmission
Inventor: WILLIG KURT
IPC: F03G1/00
Filed: 1983-01-05
Abstract: The first version of this spring motor in particular can be used as a drive in many spheres. Very high speeds produce much power for a compact, simple and cheap construction. In the case of this spring motor two quite independent systems act in concert and make it possible - the independent spring force not connected to the shaft and the unilaterally loaded armature. There might also be an angle fitted in the shaft. In connection with the hydraulic power transmission in which the speed can be steplessly controlled for a constant torque, the spring motor is also of interest as a drive for vehicles. For this reason I have included both parts together in one patent application.

Patent DE-3338814-A1 (DE)
Title: Belt retarding section for a folding unit
Inventor: KOEBLER INGO DIPL ING
IPC: B65H29/68
Filed: 1983-10-26
Abstract: The belt retarding section in a folding unit includes two cams of the same shape and eccentricity arranged on a common shaft. The belt, which at least partially winds around these cams, is diverted between the two of them, there being a simultaneous displacement from the level of one cam to the level of the other cam. The level displacement is reversed by means of a deflection and/or guiding roller which is located in the region of the retarding section. By designing and arranging the two cams on the common shaft, acceleration and retardation of the belt section are achieved in synchronism with the rotation of the cams in the retarding section, with simultaneous path compensation, so that no linear displacement of the deflection rollers is necessary.

Title: Simplified device for co-ordinate transformation in the control of rotating-field machines
Inventor: ZIMMERMANN WERNER DIPL ING
IPC: G06J1/00
Filed: 1984-03-02
Abstract: Patent Application P 3338658.7 disclosed a device for the virtually delay-free transformation of variables which change with time, between mutually rotating, flat and orthogonal co-ordinate systems, as is frequently necessary in the case of field-oriented control of converter-supplied rotating-field machines. The key idea of the invention described there is for this transformation to be carried out by means of multiplying digital/analogue converters. The complexity which is necessary for this purpose can be reduced if the device according to the invention is designed according to Fig. 5, while maintaining the above-mentioned key idea: the geometrical sum x<2>d + x<2>q<1/2 > of the orthogonal components xd and xq of the variable to be transformed is applied to the reference-signal inputs (11) of the two multiplying digital/analogue converters (12) and (15). The sine and the cosine of the sum of the angle  phi  between the co-ordinate systems and the angle  gamma , which, for example, is formed in accordance with the provision  gamma  = arcsin(xq/x<2>d + x<2>q<1/2 >), are present at the digital inputs (14) of said digital/analogue converters. The output variables (19) of the two multiplying digital/analogue converters (12) and (15) directly form the desired orthogonal output variables (10) of the co-ordinate transformation device (5). <IMAGE>

Title: Anti-aquaplaning device for passenger vehicles, lorries, aircraft and motorcycles
Inventor: DELECATE HEIKO
IPC: B60B39/00
Filed: 1984-05-09
Abstract: The invention is intended to eliminate the aquaplaning state in passenger vehicles, lorries and aircraft and motorcycles as soon as it has occurred, in that compressed air is blown on to the <<aquaplaning film>> out of nozzles with a rectangular cross-section which are arranged swivellably in front of the wheels, the satisfactory steering and control of the vehicle then being possible again. The criterion for triggering is the undershooting of a minimum torque resistance at the steering wheel. If this minimum torque resistance is undershot, compressed air is blown in front of all the wheels of the vehicle. The minimum torque of the steering wheel triggers the activation of the device by means of a torque monitor. For the wintertime, the device can be switched off by means of a switch.

Title: Device for software correlation
Inventor: HALAMEK HERBERT DIPL ING
IPC: H04L25/04
Filed: 1984-05-10
Abstract: The invention relates to a device for software correlation in data transmission systems, for example in the radar receiver of a mobile radio network. By means of the software correlation, the received phase and the signal offset are intended to be determined from the received data read into a memory, from which the clock generation can be supplied and the subsequent data stream can be read. The invention provides for this purpose that the received analog signal is converted into a binary data stream in a threshold value detector (2) assigned to the receiver (1) and this data stream is clocked with a multiple of the bit frequency and read into a memory (5). The memory (5) is connected to a processor (6) which determines the phase and the offset of the received signal relative to the clock reference of the receiver (1). The received bit stream is regenerated and read through adjustment of the phase value and correction of the offset. <IMAGE>
