Title: Reversing loop module for DC model railway - uses current sensing to change direction of supply and operate points
Inventor: HAGENMAIER GUENTER DIPL ING
IPC: A63H19/24
Filed: 1989-08-08
Abstract: The reversing loop switch over unit ascertains the used to switch over the supply polarity by current measurements in the feed lines, whilst allowing normal forward and reverse operation. It may be integrated with other control or power supply modules. The loop includes MOS bridge circuits switching over teh supply potential in response to bipolar drive circuits, in turn responsive to logic control. The logic circuitry interfaces to the current measuring circuit and to the supply direction circuit by opto-couplers feeding flip-flops via gates. The logic circuit also operates the reversing loop points. A controller has speed and direction includes slow-stop inertia circuitry and emergency braking. All conventional supplies are provided with no need for additional mains input. (11pp Dwg.No.2/8)
Patent DE-3941632-A1 (DE)
Inventor: ZIEGLER MANFRED
IPC: H04N19/593
Filed: 1989-12-15
Abstract: TV signals, for example HDTV picture signals, are distributed within or between TV studios, using a transmission rate, for example 560 Mbit/s, which is less than the data rate of the picture signal used, for example 886 Mbit/s. To this end, a coding process operates, in the case of a large number of picture sequences, without quantization and only with prediction coding and entropy coding, while in the case of very detailed picture scenes, brief quantization is carried out, so that more extensive quantization is necessary only in extremely rare cases and solely as a kind of emergency brake to prevent buffer overflow for security reasons.

Title: Electrical cable winding method - controlling impulse rotation of drum and with measured feed of cable onto drum
Inventor: STAUTMEISTER BERND DIPL ING
IPC: B65H54/28
Filed: 1991-08-17
Abstract: The method involves holding a cable drum (6) in a pendant mounting between two pivot supports (5). The drum is driven by a servo motor (8) from one side.
