Patent DE-4114203-A1 (DE)
Title: Establishing connections between circuit board components - using routing between start and target component defined by criteria relating to critical areas for circuit design
Inventor: RAITH MANUELA
IPC: H01L21/82
Filed: 1991-04-30
Abstract: An automatic process is used to establish a wiring route between a start component (S) and a target component (T). The system is used to establish connections on circuit boards. A critical region (CA) is defined in relation to the components and defines a region in which possible connections may be made without a blockage occuring. Start and finish islands (IS, IT) are defined and all sites are examined to determine if blocking points (ISBP, ISBT) exist. For each valid connection, the point must lie in the critical region and can be reached from both sides of the island. ADVANTAGE - Provides structured solution for establishing connections.

Patent DE-4216670-A1 (DE)
Inventor: RUPP ANDREAS DIPL ING
IPC: G01L5/16
Filed: 1992-05-20
Abstract: In summary, the invention makes available a measuring wheel having a hub and a rim, and having at least one connecting arrangement between hub and rim and having one or more measuring elements in or on the connecting arrangement for the purpose of measuring forces and/or moments/torques acting on the rotating measuring wheel. The connecting arrangement between hub and rim comprises a radial/tangential connecting device and an axial connecting device. The radial/tangential connecting device is constructed such that it connects the hub to the rim in a flexurally stiff fashion in the radial and tangential directions of the measuring wheel, but in a flexurally soft fashion in the axial direction, while the axial connecting device is constructed such that it connects the hub to the rim stiffly in the axial directions of the wheel and about the vertical axis and longitudinal axis of the measuring wheel, but softly, by contrast, in the remaining directions. At least one measuring element is provided in or on at least one of the connecting arrangements in order to measure that force or that moment which is transmitted between the hub and the rim in the direction in which the latter two are connected stiffly to one another by the respective connecting arrangement. <IMAGE>

Title: Thread winder with swivel lever spool holder - has relaxing piston cylinder unit engaging on lever adjusting to spool diameter
Inventor: DAMMANN PETER
IPC: B65H54/52
Filed: 1993-01-16
