Patent DE-4218938-A1 (DE)
Title: Resistance element prodn. for sliding-type potentiometer - by applying strip of electroconductive resin paste to substrate, curing resin, hot pressing polymer core round it and removing substrate
Inventor: KAZMIERCZAK HARALD DIPL ING
IPC: H01C17/00
Filed: 1992-06-10
Abstract: Elements have a resistance strip of polymerised electrically conducting paste embedded on three sides in a polymer core. The process uses a reverse laminating technique in which a suitably shaped strip layer of the uncured paste is first applied to a substrate, the polymer core is preused on top and the substrate is removed. The paste is cured on the substrate before the core is pressed on.  The core pref. contains glass fibres. ADVANTAGE - The paste can be subjected to very high temps. so that the cure time can be reduced to a few mins. The whole process can thus be shortened and mechanised. The resultant prods. have excellent surface properties and are not liable to a drift in their resistance level. The use of glass fibre filler imparts high mechanical strength and hence allows thin prods. to be used. The conducting layer can usefully be applied by a screen printing method which eliminates spraying and further simplifies mechanising the process.

Title: Simple gripper for grasping supported object
Inventor: LEWIN ANDREAS DIPL ING
IPC: B25B1/08
Filed: 1993-01-02
Abstract: The gripper has two opposed jaws (14) which are moveable along the guide surfaces (16) of the gripper body (12). A system of guide rods and guide pins ensures that the jaws remain aligned and retained in the body.The guide surfaces (16) are inclined to create a wedge space opening towards the object to be grasped.

Title: Lock, especially motor-vehicle tailgate lock
Inventor: BOEHM GUENTHER DIPL ING
IPC: E05B83/16
Filed: 1993-10-29
Abstract: The invention relates to a lock, especially to a motor-vehicle tailgate lock, with a lock cylinder (2) which is operatively connected for locking and unlocking to a pivotably mounted lever element (16), the pivotability of which is blocked in the locking position. This is to prevent the possibility of being able to open the tailgate in an unauthorised manner via the lever element (16) simply by drilling open the body panel (4). This blocking effect can be achieved in an especially simple way according to the invention in that the lever element (16) is held displaceably by at least one body-side receptacle (23) and can be brought into a positive connection with this in the event of a displacement movement initiated via the lock cylinder (2) (Figure 2).   <IMAGE>

IPC: H04B7/26
Filed: 1994-03-29
Abstract: Proposed is a vehicle-mounted transponder with at least one receive and transmit antenna for duplex data transmission, the antenna operating in the same way as a transponder. To compensate for fading, an HF amplifier is connected in series with the demodulator/modulator, thus also improving the range of the transmitter.
