Patent GB-2225757-A (GB)
Title: A motor vehicle with wheels driven via differential gearing or the like
Inventor: RICHTER KARL-HEINZ
IPC: B60K23/08
Filed: 1989-11-16
Abstract: In the case of rotational-speed differences occurring between the wheels (1, 2), a control device (10) intervenes in the distribution of the drive power of an engine (3) to the permanently driven wheels (1) and/or the wheels (2) which can be drive-connected. This intervention occurs for a particular holding time which is progressively extended if a new intervention becomes necessary after a test disconnection of the respective intervention. In addition or alternatively, the control device (10) can respond more sensitively and thus more quickly to rotational-speed differences of the wheels (1, 2) which may occur again during or after a test disconnection.

Title: Method of producing wiring harnesses
Inventor: UEDA KOICHI
IPC: H01B7/00
Filed: 1993-07-07
Abstract: In a method of producing different wiring harnesses, a subassembly (1x) of the harness that is common to all harnesses is formed using a bridging connector rather than a splice. The wires forming the subassembly are laid out using an automatic wiring machine, and portions of the wires are secured with tape (40) so that the bundle of wires is not loosened. Consequently, the subassemblies are easily united because the bundle is kept secure by the taping. In addition, the number of types of subassemblies can be decreased, and the number of wires in a subassembly can be increased. The subassemblies are easily produced using the automatic wiring machine because they have no splices. <IMAGE>
