Title: Switching a load over from an electrical mains power supply to a power supply unit
Inventor: GLEITSMANN MICHAEL
IPC: H02J9/06
Filed: 1982-12-15
Abstract: While a load (4) is being switched over, without any interruption, from an electrical mains power supply (3) to a power supply unit which has an energy store (20) and a converter (1) which is controlled via a drive unit (triggering unit) (14), a first switching element (S1) between the main power supply (3) and the load (4), and a second switching element (S2) between the load (4) and the converter (1), as well as the converter (1) itself, are intended to be controlled or regulated in such a manner that no voltage dips or spikes occur. Once the converter (1) has been synchronised to the mains power supply (3) and the converter output voltage has been matched to the mains power supply voltage, before switching over, the reference variable for a voltage regulator (12) for the converter (1) is increased while switching over is taking place, that is to say during the time in which the two switching elements are kept closed in an overlapping manner, and the voltage regulator itself is made to have more inertia. A comparator (7) is used to determine when the converter (1) has taken over the entire current for the load (4) in order then to isolate the load (4) from the mains power supply (3), using the first switching element (S1). <IMAGE>

Title: Magnetic field sensor
Inventor: DIBBERN UWE DR
IPC: G01R33/022
Filed: 1983-05-14
Abstract: The magnetic field sensor for detecting the gradient of a magnetic field consists of two series-connected sensor elements (1, 2) which form a Wheatstone bridge circuit with two resistance elements (7, 8). The sensor elements (1, 2) have parallel current paths (3, 4) of magnetoresistive material, which are magnetised in the same direction (5, 6) without the action of a magnetic field (12). When a magnetic field (12) acts upon them, the ohmic resistance values of the sensor elements (1, 2) change in the same direction so that the voltage measured in the null branch of the Wheatstone bridge is a measure of the amount of the magnetic field gradient (11). <IMAGE>
