Patent DE-3044657-A1 (DE)
Inventor: HAUK WALDEMAR DIPL ING
IPC: H04Q11/00
Filed: 1980-11-27
Abstract: A service integrated transmission system for transmitting, over a light transmission path, digital signals having a transmission band whose upper limit frequency corresponds to the maximum bit rate of the signals to be transmitted, the transmission being effected by simultaneously transmitting, over the transmission path, digital signals having a high bit rate only in an upper part of the transmission band and digital signals having a low bit rate only in a lower part of the transmission band. The system includes a transmitter at one end of the path which separately multiplexes low bit rate signals into a narrowband signal and high bit rate signals into a broadband signal, combines those multiplexed signals, and modulates a light source with the combined signal. A receiver at the other end of the path converts the modulated light signal into a demodulated electrical signal, separates the two multiplexed signals, and then demultiplexes each of the latter signals.
Patent DE-3101152-A1 (DE)
Title: Ski brake
Inventor: WEHRLI HANS
IPC: A63C7/10
Filed: 1981-01-16
Abstract: A U-shaped brake caliper (3) provided with a tread bow (9) and with at least one braking arm (13, 14) is mounted by means of shaft parts (6, 7) in a base (4) about a pivot axis (8-8) arranged perpendicularly to the longitudinal axis of the ski. Arranged between the legs (10, 11) of the tread bow (9) is a spring element (5) for example a torsion spring, which engages with one end (18) on one of the legs (10, 11) and which supplies the spring-force reserve during the transition of the brake caliper from the braking position into the position of readiness. As a result of an invisible arrangement of the spring element (5) between the legs (10, 11), a simple ski brake (2) as a solution requiring a small amount of space is provided. Nevertheless, the mounting of the shaft parts (6, 7) can be carried out in a simple way and without being influenced by the spring element (5). On account of the small space requirement of the ski brake (2), the latter can be integrated into rotary-plate safety bindings without any additional screw connection. <IMAGE>

Patent DE-3104709-A1 (DE)
Title: Annular elastomer loop for suspension purposes
Inventor: WOLF FRANZ-JOSEF
IPC: F16L3/16
Filed: 1981-02-10
Abstract: The annular elastomer loop for suspension purposes comprises an elastomer ring in which a tension spring is embedded such that, in the relieved state of the elastomer, said tension spring is likewise relieved at least to a considerable extent. An elastomer loop of this type exhibits a relatively wide, flat and, depending on requirements, easily adjustable proportional band of the stress/strain characteristic. If the tension spring and the elastomer are matched with each other such that the maximum resilient extensibility of the tension spring is considerably smaller than the elongation at break of the elastomer, then, following the widened proportional band, a strain limitation with virtually exponential stress increase is obtained.
