Title: Coin-return device
Inventor: RITZENTHALER PATRICE
IPC: G07F5/24
Filed: 1987-07-21
Abstract: A device (1) for a fraud-proof coin return of a self-service machine has an intermediate store (2), a control (9) and a switch point (4). As soon as the machine has established the amount for a service, the control (9) waits for an extraction signal from the detector (11) which indicates, for example, that a barrier (16) in front of a return tray (8) has been actuated. After the extraction signal is received, the control (9) causes the intermediate store (2) to discharge return coinage into a channel (3). By means of the switch point (4), the position of which is determined by the control (9), the return coinage is guided through a return channel (6) into the return tray (8). If the control (9) receives no extraction signal within a predetermined return time, the switch point (4) guides the return coinage released by the intermediate store (2) through a cash channel (5) into a cashbox (7). <IMAGE>

Patent DE-3743028-A1 (DE)
Title: Sulphur hexafluoride (SF6) load switching installation
Inventor: MOOZ DIETRICH
IPC: H02B1/24
Filed: 1987-12-18
Abstract: SF6 load switching installations are used increasingly in substations where they switch a cable ring or a transformer branch. Until now, fused interrupters consisting of a combination of a load interrupter and a high-current, high-voltage fuse have been used in the transformer branch. This fused interrupter combination is now increasingly being replaced by a circuit breaker. This circuit breaker has until now normally been represented by vacuum or SF6 switching chambers which have been energised for switching in the transformer output by corresponding relay converter combinations, which leads to a relatively high cost. The invention specifies an SF6 switching installation which reduces the complexity in the transformer branch by using a load interrupter 8 with a short-circuiting device 10. Such an SF6 load switching installation can advantageously be used in substations 2. <IMAGE>

Title: Process and apparatus for the longitudinal water sealing of multicore bunched cables
IPC: H01B7/285
Filed: 1988-03-18
Abstract: In a process for the longitudinal water sealing of a bunched cable having a multiplicity of cable strands, an at least two-layered dual adhesive tape is used, the first layer of which consists of a composition which adheres well at room temperature and the second layer of which consists of a hot-melt adhesive. In the region of the section to be sealed off, the dual adhesive tape is attached by its layer which adheres well at room temperature to the fanned-out cable strands of the bunched cable to be sealed off. After rolling together or folding together the layer provided with the dual adhesive tape, an outer, heat-shrinkable material (tube or film) is placed around the seal location. By heat treatment, the outer shrinkable material is made to shrink back and the two layers of the dual adhesive tape are made to melt and swell, as a result of which all the intermediate spaces between the cable strands and also between the cable strands and the outer heat-shrink material are filled with polymer material.

Patent DE-3824494-A1 (DE)
Title: Optical receiver
Inventor: HABERDITZL RAINER DIPL ING
IPC: H04B10/69
Filed: 1988-07-20
Abstract: Optical receivers with a photodiode, a transimpedance amplifier and a variable load impedance connected in parallel with the photodiode are known. Since the output signal bandwidth of the transimpedance amplifier is reduced in optical receivers of this type when the impedance of the variable load impedance falls, the same output signal bandwidth as for low optical input power is also intended to be maintained by the proposed circuit arrangement for high optical input power. For this purpose, a limiting resistor is connected in series with the parallel circuit comprising the photodiode and the variable impedance.
