Title: Mounting rack
Inventor: SEISS MICHAEL
IPC: H05K7/14
Filed: 1988-09-28
Abstract: The invention relates to a mounting rack having an insert with plug connector parts for producing connections for mating the plug connector elements on the holder side. The insertion and withdrawal of the insert requires a very large amount of force to be exerted because of the relatively high frictional resistances of the plug contacts. Furthermore, the insert must be locked in the mounting rack such that it is proof against vibration. To this end, it is proposed to lock the insert by means of a spring which is mounted in the mounting rack and, after the insert has been inserted, presses the gripping arms of the levers against abutments formed by webs.

Title: Stretch yarn texturising - using combined high and low stretch filaments fed to texturising jet together at the same speed with low stretch cladding at a higher speed
Inventor: KRENZER EBERHARD
IPC: D02G1/18
Filed: 1990-09-13
Abstract: The pneumatic texturising process for a yarn composed of a mixture of several continuous filaments, fed simultaneously but at different speeds to the texturising jet, uses a high stretch elastane filament as one component in a straight tensed condition to be joined to a low stretch filament, to be fed to the texturising jet at an identical speed. A further low stretch multifilament is passed to the texturising jet at the same time, but at a higher feed speed. After the elastane filament and accompanying filament have been joined together they pass through an eddy jet before entering the texturising jet, where an air stream braids and knots them together ahead of texturising. ADVANTAGE - The pattern of the cladding thread or filament is consistent, retaining its crimped character during further processing, and which does not affect the high stretch performance of the core.
