Title: Belt release system
Inventor: WILHELM HANS-JUERGEN
IPC: B60R22/32
Filed: 1989-02-23
Abstract: The "belt release system" is an emergency releasing device for all safety belts. It effects the separation of the belt lock from its fastening point. In this system, the belt lock has a short steel tube instead of, as formerly, a pressed-in steel cable. In the steel tube there is situated a clamping device, through which there runs a cable which is thin but which has a substantial tensile strength. One end of the cable is fastened to the pin of the belt lock which is seated in the steel tube. Between the lock and the clamping device there is seated the cable, which is taut. The other, longer end, is seated, wound up in the form of a spiral, between the clamping device and the fastening foot. The clamping device can be adjusted to a desired pulling weight by means of a small screw. The connection between the belt lock and the tube sleeve is established by means of a steel bolt which is fixed by means of a lever which is adapted to the steel tube. If the belt lock cannot be released in an emergency, for example in the case of an overturned vehicle, or an injured person needs to be rescued, the lever of this emergency release device need only be pulled to cause the person to be slowly lowered. The lock can subsequently be opened as the tensile stress of the belt is reduced.

Title: Monitoring device on sheet-processing machines
Inventor: HARTUNG WINFRIED
IPC: B65H7/14
Filed: 1989-03-09
Abstract: For monitoring the sheet transport on sheet-processing machines, two optoelectronic sensors (7, 10) are provided on the feed table (1) for the sheet (2) in the region of the front gauge (front guide stop, front lay mark) (3), and detect the beams from two light transmitters (6, 9) reflected from the sheet surface. The first sensor (7), of which the measuring position is fully on the sheet, serves for detecting faulty sheets and for measuring the diffuse reflectance of the sheet (2). The second sensor (10), of which the measuring position (11) lies with one half respectively either side of the feed line (5), detects the sheet position, its measured value being compared with the diffuse reflection of the first sensor (7). Differences in the diffuse reflectance of the sheet (2) are compensated in this way. <IMAGE>

Title: Tape, wire or thread winding machine - has electromagnetic torque control for adjusting winding rate
Inventor: STUPP PETER
IPC: B65H54/74
Filed: 1989-12-04
Abstract: The tape, wire, or thread winding machine has a winding reel (13) attached to a rotary drive spindle (11) supplied with a variable drive torque for adjusting the winding rate.  The cogwheel drive (29) rotates a housing (21) containing a sliding lamella disc (25) cooperating with a carrier (49) attached to the drive spindle (11). A variable drive torque is obtained via the friction between the lamella disc (25) and an electromagnetically operated armature disc (23) and between the lamella disc (25) and the housing (21). The armature disc (23) is moved against a spring bias by the current through a magnetic winding (67) to vary the friction force and hence the drive torque.

Title: Easy electronic chip release from wafer support foil - which is deposited onto surfaces with structural depression, with foil top side exposed to overpressure
Inventor: ROHRER HELMUT K
IPC: H01L21/00
Filed: 1990-01-24
Abstract: The process provides an easy release of electronic chips from a wafer support foil which rests on a structural surface with depressions. The underside of the support foil is exposed to a vacuum via the structured surface such that the support foil is drawn into the depressions, at least partly. The vacuum suction releases the electronic chips sticking to the foil surface. The support foil top side is in addition exposed to an overpressure, typically a stationary one. Alternately a dynamic overpressure maybe used i.e. as ultra sound. Freon may be used as a transfer medium for the ultra sound. The overpressure may be cancelled as soon as the vacuum has started to affect the support foil. ADVANTAGE - Safe release of electronic chips without excessive expense.
Patent DE-4003279-A1 (DE)
Inventor: KLEINKORRES UWE
IPC: H02G3/04
Filed: 1990-02-03
Abstract: The invention relates to a cable duct, such as a railing duct, a cable routing duct, an apparatus installation duct or the like. Such a cable duct has a lower part, whose opening can be closed by a cover. In this case, the lower part on the one hand and the cover on the other hand have interacting couplings and mating couplings which permit both fixing and removal of the cover to and from the lower part respectively. On each of the opposite boundary walls of its opening, the lower part of the cable duct has an engagement space for one of the two ends of the cover. These engagement spaces are of mutually identical design. In this way, it is intended to be ensured that optionally both the one and the other end of the cover can be inserted into one of the two engagement spaces. The respectively other end of the cover has a latch in order to lock it detachably to the lower part. The attachment end of the cover is in contrast designed in such a manner that, once unlocking has been completed, the cover can be moved optionally into a removal position or into a position where it is open as far as possible and is secured in this position.
