Patent DE-3935981-A1 (DE)
Inventor: GEIGER ERICH
IPC: H04N11/16
Filed: 1989-10-28
Abstract: In a TV transmission system which operates on the ''letter box'' principle for the 16:9 image format, every fourth line is removed and transferred as additional information to the upper and lower edges of the image, in a form compatible with the 4:3 format. Progressive pictures with 432 active lines and a picture frequency of 50 Hz are obtained by an additional signal processing in the emitter and 16:9 receiver. However, this relatively low picture frequency may give rise to large area flicker. The picture frequency is increased to 66 2/3 Hz and the large area flicker eliminated, at a constant line frequency of 31.25 kHz, by motion-matched interpolation of a fourth picture obtained from every three pictures received in the 16:9 receiver.

Patent DE-4101269-A1 (DE)
Inventor: LANGE HANS-ARNIM DIPL ING
IPC: B61L3/22
Filed: 1991-01-17
Abstract: For transmitting data provided by track devices (G1) to passing vehicles, line conductors (L) of limited extent are connected to the track devices. The track devices are cyclically activated by a control station (LST). During this process, the control station transmits, for example, call-up messages for forwarding to the associated line conductor to the respective track device via a data line (K1). If these messages are received and acknowledged by a vehicle, this is detected by the control station which, by connecting a control code (+U) to the data line, causes the track device to output the data provided by the track device. The transmission process is ended by a second acknowledgement message. If the control station sends a continuous signal outside the times needed for calling up the vehicles and possibly the reception of acknowledgements, the vehicles can carry out a self-locating process in this time via the line conductors over which they run. The special advantage of the device according to the invention is that track devices of very simple construction can be used. <IMAGE>
Patent DE-4105174-A1 (DE)
IPC: B65H51/22
Filed: 1991-02-20
Abstract: The invention relates to a delivery device for running yarns, having a rotationally fixed storage drum (4), to which the yarn (F) can be fed from the rear by means of a yarn guide (5) rotating in one direction of rotation or the other and from which the yarn (F) can be drawn off overhead, said storage drum (4) being assigned webs (26) which serve for transporting the laid-on yarn turns towards the head end and which, irrespective of the direction of rotation of the yarn guide (5), always ensure a transport towards the head end of the storage body. For the purpose of achieving the best possible mode of operation, the invention proposes that the adjustment for adaptation to the direction of rotation of the yarn guide (5) results automatically from the driving force of the yarn-guide drive shaft (3). <IMAGE>

Title: Generating calling AC voltage in telephone subscriber circuit - producing DC voltage with amplitude control by pulses of different pulse-interval ratio
Inventor: GUENTHER WOLFDIETRICH
IPC: H02M7/48
Filed: 1991-02-21
Abstract: In the process a d.c. voltage (G), with controllable amplitude, is generated by pulses (I) of different pulse-interval ratio. The d.c. voltage is converted into a call a.c. voltage (Ru) by polarisation change. The call a.c. voltage is compared with a reference a.c. voltage (Re), generated in the process. The pulse-interval ratio is adjusted in dependence on the comparison result, producing a control voltage (S). A changeover signal (U) is generated when the width of the pulses is below a defined time value in the first or third quadrants of the call a.c. voltage period. The call a.c. voltage is switched off, when in the third quadrant the changeover signal is not generated after a defined second time value. USE/ADVANTAGE - For subscriber line interface circuits. Uses isolating converter already used for low-loss provision and limiting of subcriber loop current.

Title: Steering axle with self-blocking differential gear - has driven shaft forming abutment for spring with axial force changing closing force of friction coupling
Inventor: HAUPT JOSEF
IPC: B60K17/30
Filed: 1991-04-13
Abstract: The driven shaft (14) of the axle assembly forms an abutment for a spring (16) with axial spring force which changes the closing force of a friction coupling in such a way that with increasing steering angle the friction coupling`s torque becomes less. Torque from a sun wheel (3) produces outwardly acting axial force of the central gearwheel (7) via the moving teeth (8, 9) of the satellite wheel (6) and central gearwheel (7). The axial force produces torque in the friction coupling (13). ADVANTAGE - Sufficient traction force for straight cross-country travel is created without any additional coupling.
