Abstract: A device for determining the local direction of a magnetic field has (i) two superconductive elements (4,5), each having a prenounced resistance anisotropy dependent on the position of a predetermined plane (4a,5a) relative to the magnetic field direction and each passing a current in a preferred direction (h1,h2) in this plane (4a,5a), the two planes (4a,5a) being mutually orthogonal; (ii) a system for cooling the elements (4,5) to a predetermined operating temp. (T) below the critical temp.; (iii) a system for rotating the elements (4,5) about axes (D2,D1) parallel to the preferred directions (h1,h2); and (iv) a system for measuring the voltage (U1,U2) across each element (4,5) in the preferred direction (h1,h2) when a constant supercritical current (I1,I2) flows in the preferred direction (h1,h2).

Filed: 1992-02-19
Abstract: The two small glow lamps are the light sensors. The illumination of the two glow lamps with a 100 watt bulb, at the measurement output a voltage of approximately 60 volts DC is obtained. A small mirror positioned behind the glow lamps doubles the voltage. Illumination by the sun gives a voltage of approximately 60 volts without the mirror. The responsitivity takes place, about 30 mins after the switching off of the street illumination. A microammeter can be used instead of the voltmeter. USE/ADVANTAGE - Light voltage measuring unit. Proves that light can have much higher voltage than 2.47 volts.

IPC: F15B11/05
Filed: 1992-07-16
Abstract: The invention concerns a control unit for at least one hydraulic consumer, the direction and speed of operation of the consumer being controlled by means of a distributor valve (14). Two lines (21, 22) lead from the distributor valve (14) to the consumer, each consumer line being connected by means of a distributor-valve piston (15) and a calibrated orifice (30) to a pump (85) and hence a reservoir. Each consumer line has a throttle valve (23) with a control piston (34). The aim of the invention is to be able to keep the consumer in a particular position without loss of hydraulic fluid. This is achieved by virtue of the fact that the throttle-valve (23) control piston (34) is located downstream of the distributor-valve piston (15) and the calibrated orifice (30) in the line (21, 22). A valve seat (35) is acted on by the control piston (34). The front of the control piston (34) has a first pressure surface (36) which is acted on, to open the throttle valve (23),  by the pressure in the respective consumer line (21, 22) downstream of the distributor valve (14) and the calibrated orifice (30), the rear of the control piston (14) has a second pressure surface (41) which is acted on, to close the throttle valve (23), by a control pressure generated only by the load in the position of rest of the distributor valve (15), and the front of the control piston has a third pressure surface (40) which is acted on, to open the throttle valve (23), by the load pressure in the respective consumer line (21, 22) between the throttle valve (23) and the consumer. When the pressure is released in the respective consumer line (21, 22) to the reservoir, the pressure acting on the second pressure surface (41) is reduced.

Title: Lighting device for vehicles
Inventor: NEUMANN RAINER DIPL PHYS DR
IPC: F21V11/16

Abstract: The lighting device has a light generating unit (10) with a light source from which waveguides (14) lead off, the said waveguides (14) being connected to light distributor units (16) which serve for different lighting functions. One of the light distributor units (16) serves for a main-beam lighting function and it is assigned a reflective shielding device (20) which can be adjusted between a passive position and an active position. In its passive position the shielding device (20) is arranged outside the beam path of the light emerging from the associated waveguide (14) so that the main-beam lighting function is switched on. In its active position the shielding device (20) is arranged in the beam path of the light which emerges from the associated waveguide (14) and reflects the light impinging on it onto a further reflection element (26) which in turn reflects the light into another light distributor unit (16) which serves for the dipped-headlight lighting function. As a result, the light which is shielded when the main-beam function is switched off is used appropriately for the dipped-headlight function. <IMAGE>

Title: Valve for a hydraulic level control in vehicles, preferably motor vehicles
Inventor: NIETHAMMER BERND
IPC: B60G17/056
Filed: 1993-05-11
Abstract: With such hydraulic level controls the ground clearance of the vehicle can be adjusted, for example as a function of the load condition. For controlling the level, hydraulic medium is fed in or led off by means of the valve. The valve has a control shaft on which a rotationally fixed control disc is seated, which is accommodated in a pressure chamber. A tank bore, which can be connected to a tank of the level control and the passage of which can be varied by means of the control disc, opens into the said chamber. So that only a low torque is required for adjustment of the control shaft and the control disc, the free end of the control shaft lies outside the pressure chamber and is sealed off from it. The valve makes hydraulic level control in vehicles possible, the vehicle being adjustable to the optimum level at any given time.
