Patent DE-19646359-A1 (DE)
Title: Lubricating oil pump controlled by volumetric degree of effect
Inventor: BACHMANN JOSEF
IPC: F16N13/20
Filed: 1996-11-09
Abstract: The sealing rib separates the suction pocket (2) from the pressure pocket (3). It is replaced by a movable piston (1). Through the controlled drawing back of the control piston, a by-pass is formed between the suction pocket and the pressure pocket and at the same time the axial play in the sealing area is enlarged. Through the by-pass regulation in the sealing rib area or control piston, and the specific control of the control piston, the volume flow can be matched to the requirements of an internal combustion engine. The volumetric degree of effect of the lubricating oil pump can be so regulated via different control possibilities of the control piston that the power take-off of the lubricating oil pump can be considerably reduced.

Title: Measuring device for material surface esp. for soft, elastic material, e.g. plastics
Inventor: HAPP BURKHARD DR
IPC: G01B11/16
Filed: 1996-12-07
Abstract: The device deforms the surface to be examined through a rigid transparent test body in a defined way. A contact image in reflected light is recorded through a CCD camera, and processed with an electronic image processing system.

Title: Headlight system for vehicle with optical-fibre elements
Inventor: FOERSTNER ROLF
IPC: F21V8/00
Filed: 1996-12-14
Abstract: The vehicle headlamp unit has a conventional reflector with main and dipped beam lamps and has the lens surrounded by optical light-guides which provide the additional lighting e.g. parking lights, indicator lights etc. These additional lights are provided via light-guides (20,32) which transfer light from remote mounted lamp units (24,26) to outlet points around the headlamp.

Patent DE-19701273-A1 (DE)
Title: Coupling for trailer on road vehicle
Inventor: WYRWICH MARTIN DIPL ING
IPC: B60D1/52
Filed: 1997-01-16
Abstract: The coupling device is for a trailer for a road vehicle. It uses a ball (1) which may be accommodated in a bore (14b) in the wall of a hollow coupling member (14). The ball may be forced outward by a gently tapered central plug (8) with a steeply tapered end (8b). The plug is urged forward by a coil spring (16) to force the ball outward into a groove (3a) in a collar (3) fitting inside a guide housing (2). The plug contains a blind bore (8a) containing a coil spring (10) which urges a small ball (11) outward against a larger ball (12) which presses against a profiled inside surface of the guide housing. As the inner member is forced into the outer member this ball forces the smaller ball inwards, releasing the plug and allowing it to slide forward and push the first ball into the groove to lock the coupling.
Patent DE-19702187-A1 (DE)
Inventor: GOEDICKE KLAUS
IPC: H01J37/34
Filed: 1997-01-23
Abstract: Magnetron discharges are pulse-operated to avoid the so-called "arcing". In the case of magnetron discharges from alternating current-fed magnetrons, the process is limited to the minor power of the energy supply because of the load-carrying capacity of the required electric components. When the magnetron discharges are fed by direct current, their effectiveness deteriorates because of the deposition of layers on the anode surfaces. The new process should enable a high supply power without arcing. In magnetron discharges with at least two magnetron electrodes, the energy is supplied in such a way that at least one magnetron electrode is a cathode or anode and a number n1 of direct current pulses of said polarity is supplied. The poles of at least one magnetron electrode are then reversed and a number n2 of direct currents of this polarity are supplied. The process is carried on in this manner, the frequency of the direct current pulses being higher than that of the polarity reversals. The energy supply effectiveness is thus improved. This process and system enable the production of layers having the most different properties, for example for the glass, packaging, electronic and machine construction industries.
