Title: Flow division valve for hydraulic systems - has spring-loaded control piston and control aperture with variable dia. pin
Inventor: REICHENMILLER MICHAEL
IPC: G05D16/10
Filed: 1990-12-12
Abstract: A flow division valve for hydraulic systems has a feed in a housing connected to a pump and connectors for first and second loads.

Title: Electrical system for motor vehicle - incorporates generator supplying output voltage and battery taking charging voltage at max. level dependent on temp. for regulating generator output voltage
Inventor: BUSCH REINHARD
IPC: H02J7/14
Filed: 1991-01-31
Abstract: The system is provided with a generator regulator (1) and a battery regulator (2). A temp. signal (TG) from a temp. sensor (S1) to the generator (G) is fed to an evaluation unit (11).

The voltage value (UL) to the head light lamps (L) is the input signal of a third evaluation unit (12) which with the lamps switched on sends the `Lamp On' condition to a fourth evaluation unit (13). The theoretical voltage value (UL Soll) and the actual voltage value (UL Ist) are sent by the fourth evaluation unit to the second (15). A fifth evaluation unit (14) receives its input signal (I) from the battery regulator (2) and passes it on to the second such unit (15), which contains a decision logic activating an increase or redn. of the generator output voltage dependent upon the data received from the first, fourth and fifth evaluation units (11,13,14).

Title: Magnetising permanent magnets using multi-pole pulse-magnetising device - superimposing two field pulses which reach their maxima for north and south poles at different times
Inventor: STEINGROEVER DIETRICH
IPC: H01F13/00
Filed: 1991-03-19
Abstract: The method is used to magnetise highly coercive multipole permanent magnets (1) with a multi-pole magnetising device (3). Two field pulses (H1,H2) are superimposed. Those fields are a first unipolar constant amplitude pulse (H1) and a second bipolar alternating field pulse (H2). The fields of both pulses (H1,H2) are added together for the north (N) and south (S) poles of the magnet (1) without reversing the field direction. The field maxima (H4,H5) for the north and south poles are about double the amplitude of the individual fields (H1,H2). The maxima (H4,H5) of the two poles (N,S) are not reached simultaneously, but one after the other. Thus, the overall resulting energy is less than simultaneous magnetising using a single field pulse. The maximum amplitude of the alternating field (H2) is preferably the same as the amplitude of the first pulse (H1). ADVANTAGE - Limits maximum energy required so is more efficient.

Title: Identifying short-circuited controllable semiconductor component in mains-commutated bridge circuit - triggering components irrespective of normal triggering sequence with delayed pulses and evaluating fault currents
Inventor: HEILAND KLAUS-FRIEDRICH DIPL I
IPC: G01R31/40
Filed: 1991-09-27
Abstract: The method involves shifting the position of the main pulse towards rectifier operation until a fault current is detectable. Irrespective of the normal sequence of component switching, a selected component is triggered with a single pulse with a delay angle such that output is not caused if there is a short. The main current is measured and if no fault current is detected a component in the next phase arm of the bridge is triggered. If a fault current is detected it is stored and the opposite polarity component in the same arm triggered. The fault is located by comparing the measured error current with the previously measured one. ADVANTAGE - Eliminates blowing of fuses and enables triggering of controlled semiconducting components, e.g. thyristors, irrespective of their normal switching sequence.

Title: Steel strip annealing - uses controlled feed of protective gas according to surface area of the material
Inventor: GOERSDORF WOLFGANG DIPL ING
IPC: C21D9/52
Filed: 1991-12-13
