Abstract: PCT No. PCT/DE88/00651 Sec. 371 Date Jun. 19, 1990 Sec. 102(e) Date Jun. 19, 1990 PCT Filed Oct. 24, 1988 PCT Pub. No. WO89/06048 PCT Pub. Date Jun. 29, 1989.The risk of a latch-up is diminished by the incorporation of an additional bypass transistor between the output (OUT) and the supply voltage (VDD) of an integrated circuit, for example a CMOS output stage. In case positive over-voltages that are greater than the sum of the supply voltage (VDD) and the conducting-state voltage of the bypass transistor occur at the output (OUT), the bypass transistor becomes conductive and represents a low-impedance connection between the output (OUT) and the supply voltage (VDD). In this case, the bypass transistor (BT) suctions additional charge carriers off and thereby increases the trigger current needed for the appearance of latch-up. The incorporation of an additional bypases transistor is possible both given well-shaped semiconductor zones that lie at a fixed potential as well as given well-shaped semiconductor zones that are wired to a variable potential.

Title: Apparatus for the winding of a thread
Inventor: DAMMANN PETER DIPL ING
IPC: B65H54/553
Filed: 1988-01-28
Abstract: What is described is a winding apparatus for the winding of a thread 14 onto a winding tube 16, which has devices for making it easier to remove and handle the finished bobbins 20 and by means of which the preconditions for an automated bobbin change are afforded. Thus, the full bobbin 20, with a predetermined bobbin thickness, is lifted off from its drive 11 and retained in this position, so that the bobbin change can, if appropriate, be carried out automatically. The devices consist of a supporting device which is located on both sides of the bobbin 20 in the region of the non-wound winding-tube ends and which is mounted stationarily, independently of the arms of the U-shaped bobbin lever 3, and is guided in such a way that, after the bobbin 20 has been lifted off from the driving roller 11 and before or after the bobbin 20 has been stopped by the brakeable centering plates, the supporting device is moved under the ends of the bobbin tube 16. The supporting device is formed particularly by two supporting cheeks 8 which are pivoted into the path of movement of the bobbin 20 and which are arranged fixedly in terms of rotation preferably on a common pivot axis 10.

Title: Electronic timer for engine-independent vehicle heaters
Inventor: GISKE DIETRICH DIPL ING
IPC: F23N5/20
Filed: 1988-05-09
Abstract: The electronic timer can be used in engine-independent vehicle heaters which operate according to the principle of rotational atomisation, the evaporator principle and the high-pressure atomisation principle. The square-wave voltage produced by an astable generator is fed to the first input of two NAND gates which are connected in series and have two inputs and the second inputs of which are driven in each case to reach the operating state and the run-on time. An integrated circuit consisting of two 4-digit binary incrementors connected in series is connected downstream of these two gates and the output signals of the said incrementors, negated by gates, control function units of the heating devices. The signal which terminates the run-on simultaneously resets a flip-flop which, by means of its output, causes the counters to be reset and initiates a single restart. The control times can vary greatly depending on the combustion principle selected. This electronic timer ensures that the times can be freely selected independently of one another. <IMAGE>

Title: Transport arrangement for the welding-wire feed on welding equipment
Inventor: RIPPL PETER DR ING
IPC: B23K9/133
Filed: 1988-08-12
Abstract: The invention deals with the control of the welding-wire feed on welding equipment. In order to deliver the welding wire (2) at constant force even in the face of unfavourable actions of force and avoid tensile or compressive stresses, the welding wire (2) is guided between a pushing drive (3) and a pulling drive (6) through a yielding part (4) and a curved tube (8). The tube tension is assisted by a spring (11). The yielding part (4, 9) is coupled to a control member (13) which measures the yielding travel of the yielding part (4, 9) when compressive or tensile stresses develop at the welding wire (2) and feeds it to a control system for compensation via speed control of the first drive (3). In this way, even very soft and thin welding wires (2), for example made of tin, aluminium or the like, can be delivered without problem. <IMAGE>
Patent DE-3833600-A1 (DE)
Inventor: ZOLLER ROBERT ANDREW
IPC: B29C48/21
Filed: 1988-10-03
Abstract: A trim molding for attachment to a vehicle includes a core member and an outer layer, preferably of elastomeric material, extruded about one side of the core member. The core member comprises a polymeric material that will not transmit vibrations; this prevents a joint line and ridges caused by vibration from appearing in the outer layer during extrusion. A smooth continuous surface on the outer layer is thus obtained. In addition, a method of making the trim molding comprises extruding a core member of a polymeric material and extruding an outer layer of an elastomeric material about one side of the core member. These two extruding steps may be carried out simultaneously, whereby the core member prevents the formation of joint lines, as well as ridges due to vibrations transmitted at the extrusion die, from appearing in the outer layer.
