Title: Demultiplexer frame sync. for time multiplexing - initiates new synchronisation cycle when one third of bits of sync. word are false
Inventor: SZIGETI TIBOR DIPL ING
IPC: H04J3/06
Filed: 1980-08-27
Abstract: The method of improving the frame synchronisation of plesiochronic demultiplexers for time multiplex systems of higher order is used where the frame structure includes additional information with the flow of information for each lower system. This additional information includes synchronising words and bits. Two bits act as markers for divergencies of direction and identification for the lower system. Up to a third of all the bits of a synchronising word may be faulty. When a demultiplexer reaches a fully synchronised condition, a new synchronising cycle is started when a third of the bits are false or when three markers are detected in sequence indicating a fault. A synchronising word can incorporate up to four faults before a new synchronising cycle is initiated.

Title: Pivot mounting for door retention bands of door stays for motor vehicle doors
Inventor: BROCKHAUS ERNST
IPC: E05C17/04
Filed: 1981-07-01
Abstract: For articulating tops or flaps on motor vehicles, use is made, in conjunction with preferably maintenance-free hinge mountings (1), of arcuately curved hinge arms which are attached to the hinge mounting (1) and can be secured on the pivotable part, top or flap by means of securing means, screws or the like passing through them, a considerable expenditure being necessary with regard to the space requirement and the strength of the hinge arm in its long, self-supporting area, whether it be because the hinge arm consists of a closed hollow profile or because the hinge arm consists of a part which is designed in one piece with the one part of the hinge mounting. In order to avoid the disadvantages of the known designs of hinge arms, the invention therefore proposes that the hinge arm should consist, in its arcuately curved, self-supporting area (2) adjoining the hinge mounting (1), of a first part formed by a hollow profile section, and should consist, in its area lying opposite the pivot mounting (1), of a second securing part (3) which is attached at an obtuse angle to the hollow profile section (2) and has an open profile cross-section, and both parts (2 and 3) are connected to one another by welding (10). <IMAGE>
