Title: Mounting rack with assemblies for digital telecommunications (information technology)
Inventor: BUTSCHER MANFRED DIPL ING
IPC: H05K9/00
Filed: 1993-05-19
Abstract: The invention relates to a mounting rack which is fitted with assemblies for digital telecommunications and is connected by means of a transfer system (gateway system) to other mounting racks and to the environment. The prior art provides that the mounting rack is designed as a closed metal box and has holes through which the prefabricated optical fibre cables of the transfer system are inserted. The holes are large enough that the plug connectors which are fitted to the ends of the optical fibre cables pass through. These large holes have an adverse effect on the screening effect of the mounting rack. The invention avoids the adverse effect on the screening effect in that the optical fibre cables (LWL) are inserted into slots (Schl) in a mounting rack transverse rail (BQS). The width of the slots is designed to be only slightly larger than the diameter of the respective optical fibre cable (Fig. 1a). <IMAGE>

Title: Anti-theft device as an immobiliser on a motor vehicle
Inventor: LEDENDECKER INGO DIPL ING
IPC: B60R25/04
Filed: 1993-05-21
Abstract: The invention relates to an anti-theft device as an immobiliser on a motor vehicle having a vehicle key (21) in which a transponder (23) is integrated and having an ignition lock (22) in the vicinity of which there is a transmission coil (26) with connected read-out and evaluation electronics (27). In a control unit, the transponder code which is received from the read-out electronics (27) when the ignition switch is actuated is compared with a stored code for identification. In the event of the codes being identical, a component (30) whose operation is blocked when the vehicle is parked is enabled again. According to the invention, a new vehicle key with an associated transponder code for the vehicle is made capable of being used by means of an initialisation process in that an initialisation code is entered via a manually activated control element (9, 10) for inputting digital information. When identity between the initialisation code which has been input and an initialisation code which has been previously stored in a memory is established, the storage of the new transponder code in the memory is enabled. As a result, it is possible to replace a defective key or to authorise further keys for the use with the vehicle. <IMAGE>
