Title: Method for producing a three-dimensional conductor moulding having a recessed conductor-track layout
Inventor: ROEMER MICHAEL DIPL CHEM DR
IPC: C23F1/02
Filed: 1988-09-20
Abstract: The invention relates to a method for producing conductor-track networks on non-conductive three-dimensional substrates, characterised in that   a) the conductive structure of the moulding is recessed deeper than the level of the dielectric of the ready-to-use circuit, b) the moulding formed in this way is metallised over the entire surface in the normal manner, c) an insulating varnish or insulating dust is applied which uses the depressions in the conductor-track network as a flowing bed in order to spread and carry out its insulating function, d) the insulating varnish or dust is removed from the copper-coated substrate surface once those raised planar plateaux of the moulding which are not intended to carry out the function of a conductor-track network have cured, e) the insulating varnish or dust remains in those conductor-track networks and contact-making holes which are recessed, f) the conductor-track network is produced in etching solutions by dissolving the copper surfaces which are not protected by the insulating varnish or dust.

Patent DE-3844436-A1 (DE)
Inventor: RELITZ HARTMUT DIPL ING
IPC: B30B11/00
Filed: 1988-12-31
Abstract: A screw shaft propels, through a pressing basket, material which is to be pressed, e.g. foodstuffs. The current input of a main screw drive motor 1 is measured 2, the measured value being processed in a computing unit 3 which compares it with a preset desired value of current. The resulting difference is used to adjust a voltage regulator 4 which controls the speed of the motor 5 driving the dispensing screw 6. The aim is to subject the equipment to the highest possible loading, guaranteeing an optimum degree of filling of the equipment, while safeguarding the screws against excessive wear and tear. <IMAGE>

Title: Variable speed servo drive for vehicle accessories - has electro-viscous clutch and constant drive electric motor
Inventor: RACHNER HORST
IPC: B60S1/08
Filed: 1989-07-12
Abstract: The electric servo motor (10) is driven at constant speed and the torque transferred by the variable viscous clutch (20).

For an interval drive a simple timer provides inter-mittent servo drive. When used for windscreen wipers the wiper speed can be adapted to the exact conditions on the windscreen. The principle is used for other servo drives, e.g.seat adjustment, window winders, in which a single motor is coupled to several drives by the separate clutches , thus reducing the number of servo motors required. ADVANTAGE - Simple motor, variable output control.

Patent DE-4023023-A1 (DE)
Inventor: BAMMEL MICHAEL DIPL ING
IPC: B64F1/22
Filed: 1990-07-19
Abstract: A tractor for manoeuvring aircraft without a towbar comprises a chassis with a forked attachment space between the wheels of one axle in which is fitted a retractable gripping and retracting device, co-operating with a lifting device, by means of which the nose wheel of the aircraft can be grasped and pulled on to a spade.
