Patent DE-3320205-A1 (DE)
Title: Distribution box
Inventor: STRIEBEL FRANZ
IPC: H02G3/08
Filed: 1983-06-03
Abstract: Cables which are introduced into distribution boxes (1) are firmly clamped there jointly by means of clamping strips which engage over them, and are relieved by tension here. Since the cables which are used are of different thicknesses, this leads to individual cables being crushed (pinched) while others are not yet gripped by the fixing and are not fixed with respect to tensile and shear forces. In order to improve the tension relief (strain relief), it is proposed according to the invention that the opposing rails are constructed as pressure strips (11) in which a multiplicity of individually adjustable clamping parts (12) are arranged for the individual cables (29). <IMAGE>

Patent DE-3447039-A1 (DE)
Title: Central locking system for motor vehicles
Inventor: STERLER GEORG DIPL ING
IPC: E05B77/46
Filed: 1984-12-22
Abstract: In a central locking system, the door contact (3) of the front seat passenger's door is interrogated and, if the front seat passenger's door proves not to be closed, a locking command triggered by the internal actuation element of the front seat passenger's door is not accepted by a control unit (19) which controls the central locking and, if appropriate, an unlocking command is executed. As a result, unintentional locking of all the doors by the front seat passenger when he leaves the vehicle is prevented, but the said front seat passenger is still enabled, in a hazardous situation, to lock the vehicle centrally from the inside when the doors are closed if the driver is not in the vehicle at that time. <IMAGE>
Patent DE-3447668-A1 (DE)
Title: Transport device
IPC: B61D9/00
Filed: 1984-12-28
Abstract: Cable-driven transport trains have consisted until now of a towing vehicle and at least one transport vehicle. Since the transport train is operated in both directions of travel, large deflection forces act on the vehicle units and the connecting elements thereof in a negative fashion in particular when in thrust mode on inclines and when going around bends. In order to avoid this, a towing vehicle 2, 3 is provided at each end of the transport train 5. The towing cable 11 is joined to both towing vehicles 2, 3. Between the towing vehicles 2, 3, a compensation cable 15 is arranged whose ends are influenced by length-compensating springs 17, 20. In this way, cable compensation between the towing vehicles 2, 3 takes place. The negative influence of thrust forces is thus avoided. <IMAGE>
