Title: Child restraint device
Inventor: CZERNAKOWSKI WALDEMAR
IPC: B60N2/28
Filed: 1984-06-19
Abstract: The restraint device consists of a dimensionally stable shell (3) and is arranged on a frame (4), fitted onto the seat upholstery (2.1) of a vehicle seat (2), with free spacing above the seat upholstery (2.1) and is held, together with the frame (4) by means of a customary seat belt (5) assigned to the vehicle seat (2). The child is directed backwards here and lies with the longitudinal axis of its body essentially in the longitudinal direction of the vehicle and inclined upwards towards the horizontal. The seat belt (5) runs transversely over the shell (3) through belt receptacles (6) provided on both sides of the shell (3) and as a result determines a swivel axis (8) for the shell (3), which axis (8) lies above the centre of gravity of the system consisting of the shell (3) and the child. The frame (4) itself is additionally held securely on the seat upholstery (2.1) by the seat belt (5) and is movably connected to the shell (3) in a guide (11) running below the swivel axis (8) in such a way that the shell (3) can be rotated about a guide axis (12) which can be displaced in the guide (11) transversely to itself via the seat upholstery (2.1) and is parallel to the swivel axis (8). In the event of a head-on collision, the shell (3) can therefore move onto the frame (4) and be aligned in the direction of the arrow (13). <IMAGE>

Title: Circuit for detecting touching contacts in light signals
Inventor: MEIER JOACHIM
IPC: B61L7/10
Filed: 1984-07-06
Abstract: In light signals in which in each case at least one signalling lamp is switched on continuously whilst at least one other signalling lamp is switched off, the signalling lamps are fed via separately switchable feed lines (1, 2) and a common return line (R). Behind the switch-on contacts (S1/1, S2/1) which switch the signalling lamps (L1, L2), the feed lines (1, 2) are connected by means of a high-impedance monitor relay (U) which is connected in parallel, via the signalling lamp (e.g. L1) which is respectively switched off in terms of operation, to the signalling lamp (L2) which is respectively switched on in terms of operation. The monitor relay (U) is excited during this process unless a defect is present or the line (1) which is switched off in terms of operation is in contact (K) with a potential-conducting line (2). The monitor relay then opens and deactivates the light signal. <IMAGE>

Patent DE-3501663-A1 (DE)
Title: Mechanism wheel with variable transmission ratio
Inventor: MAGER WERNER
IPC: F16H9/10
Filed: 1985-01-19
Abstract: A mechanism wheel for a chain mechanism consists of a sun wheel (7), mounted at the periphery of which, by way of one-way clutches (23) are chain wheels (24) on guide elements which are mounted in a manner which allows them to be displaced relative to the sun wheel (7) between two radial limiting positions. The guide elements are at the same time supported on the circumference of an oval guiding body (10) which is displaceable in a straight line along a diametral line of the sun wheel (7) and is acted upon in this direction by a spring element (17). The radial position of the guide elements relative to the sun wheel (7) is determined by an equilibrium between the forces to be transmitted by the chain (6), on the one hand, and the opposing force of the spring element (17), on the other hand. In this way, an equilibrium of forces, a particular radial position of the guide elements and hence a particular effective radius of the mechanism wheel corresponding to the tensile force to be transmitted by the chain (6) is obtained. The transmission ratio is thus adjusted automatically in accordance with the particular tensile force in the chain (6). <IMAGE>

Filed: 1985-05-11
Abstract: An electrically erasable programmable read-only memory (EEPROM) is used, in which the available number of memory locations is at least twice as great as the required number of memory locations. The available number of memory locations is divided into at least two sub-areas. The electrically erasable programmable read-only memory (EEPROM) is operated in such a way that, in a first operating phase, only memory locations in the first sub-area are selected and the number of programming and erasing cycles carried out is continuously counted and, on reaching a predetermined value, in a next operating phase only memory locations in the predetermined next sub-area are selected, the number of programming and erasing cycles carried out again being continuously counted. This method is continued until, in the last of the predetermined sub-areas, the number of programming and erasing cycles carried out coincides with the predetermined value.

Title: Arrangement for monitoring an electrical fuse element
Inventor: ZEIS JUERGEN DIPL ING
IPC: G01R31/02
Filed: 1985-11-12
Abstract: The invention relates to an electrical circuit arrangement for monitoring a fuse element, for example a fusible link which, in particular, is connected floatingly to a high electrical potential. The monitoring is independent of the equipment current flowing through the fuse element, in addition there is a potential isolation between the fuse element and an associated indicating device, for example an incandescent or glow lamp. This is essentially achieved by a transformer, the secondary-side current of which is rectified and is conducted together with the equipment current as measuring current through the fuse element. Depending on the measuring current, an electrical signal, which is supplied to an indicating device, is produced on the primary side of the transformer.
