Title: Medium frequency bridge inverter with series oscillatory circuit
Inventor: KOKES MICHAEL
IPC: B60L11/18
Filed: 1996-06-17
Abstract: A series oscillatory circuit bridge inverter for feeding an AC network has a transistor bridge (1) with protective diodes and a control unit. The condenser of the oscillatory circuit is designed so that the current through it is discontinuous. The output of the circuit is joined to the input of a rectifier bridge working as a voltage limiter, whose output is parallel to the inverter input.  In feed operation, the diodes of the rectifier do not conduct and only conduct when a load feeds back energy or with load shedding, the energy stored in the condenser of the oscillatory circuit is passed to the input of the inverter or a DC source.

Patent DE-19652046-A1 (DE)
Title: Temperature measuring method of semiconductor chip
Inventor: DRAXELMAYR DIETER DR
IPC: G01K7/01
Filed: 1996-12-13
Abstract: The method of determining the temperature of a semiconductor chip (1) involves applying voltages or currents to selected semiconductor chip terminals. The voltages or currents have a polarity and value such that the resulting current flow in the chip and/or the resulting voltage are determined at least partly by a diode (D1,D2) or a similarly acting structure between the selected terminals.  The resulting voltage and current values are determined. The temperature of the chip is then derived from the determined current and voltage values using a current/voltage temperature allocation previously determined for the chip or chip type under investigation. The diode or the like for temperature measurement may be blocked in normal operation of the chip (1) and set to conduct for temperature measurement. The diode may be an over-voltage protective device.

Patent DE-19700402-A1 (DE)
Inventor: PEER FERDINAND DR
IPC: A61B34/00
Filed: 1997-01-08
Abstract: The invention relates to an instrument for the manipulation of fine structures which detects trembling of the hand, which it compensates by countermovements of the tip of the instrument. A possible principle area of application is in microsurgery, as the activities carried out there can be obstructed by the trembling of the hand of the operator. Trembling of the hand is detected by movement sensors, by repeated analysis of the position of the part (1) of the instrument held by the hand, or by deriving electromyographic signals from the operator's forearm. Intentional and unintentional movements are distinguished from each other by one or more criteria, such as amplitude, speed, frequency and direction of the movement. In order to compensate undesired movements, signals are sent to an arrangement of actors (3), which, at the mobile part (4) of the instrument, cause deviations which compensate the hand trembling at the tip of the tool. When the instrument is used as a needle holder in surgery, the actors (3) can also be controled in such a way on the push of a button that they facilitate, by oscillation, penetration of the sewing needle into the object being treated.

Patent DE-19704001-A1 (DE)
Title: Method for measuring wind speed measurement using ultrasound
Inventor: EHNERT JOCHEN
IPC: G01P5/24
Filed: 1997-02-04
Abstract: The method involves measuring the time shift,  DELTA t, of ultrasound waves. The wind speed is computed from the time shift using the formula: v = c/((s/c DELTA t)-1), where s is the distance between the transmitter and retriever, c is the speed of the ultrasound waves, and v is the wind speed. A gate opening of a circuit results in the time shift. The time duration is measured using a circuit. The wind speed is computed from the measurement using a computer programme.

Patent DE-19712732-A1 (DE)
Inventor: SIEGEL HEINZ
IPC: B60T8/40
Filed: 1997-03-26
Abstract: The aim of the invention is to create an inexpensive hydraulic vehicle braking system with an anti-blocking device enabling the braking pressures in front wheel brakes and rear wheel brakes which are connected to diagonal brake circuits in a four-wheeled vehicle to be altered extensively, independently of one another, in order to reduce or eliminate the risk of wheel lock. Said anti-lock device should have a return pump for each brake circuit. The anti-blocking device (15) is equipped with a total of six electrically controlled valves. A first valve (28, 29) between the master brake cylinder (2) and a front wheel brake (7, 8), a second valve (30, 31) between said master brake cylinder (2) and the rear wheel brake (11, 12) and a third valve (32, 33) between the front wheel brake (7,8) and an inlet (49) of each of the return pumps (34,35) are situated in each of the brake circuits. The inlets (49) of said return pumps (34, 35) are each indirectly connected to the rear wheel brakes by means of return valves (37) which can be opened to said inlets (49) of said return pumps (34, 35). The anti-blocking device has an inexpensive design and makes it possible for rear wheel braking pressures to be higher than front wheel braking pressures during operation of said anti-blocking device, for example on an icy road, to ensure more effective braking.

Patent DE-19721812-A1 (DE)
Title: Dimmer for controlling mains-operated lamps
Inventor: GEORGI MARTIN
IPC: H05B39/04
Filed: 1997-05-26
Abstract: The dimmer controls the connected load using phase switching technology. The control of ohmic loads and-or capacitative loads is possible. There is a connection to an external control voltage which is separated galvanically from the mains voltage by an optical isolator. Minimal radio interference is caused by the phase switching and only a capacitance is used to limit the interference radiation. Acoustic interference noise that arises is reduced conditionally. A large part of the loss power is eliminated, with simultaneous reduced heat generation, by using a large internal parallel capacitance.

Filed: 1997-06-09
Abstract: It is a known fact that a hydraulic unit in a motor vehicle braking system can be elastically suspended by using at least two hollow cylindrical rubber-elastic elements, into which pins jutting out from the hydraulic unit protrude, wherein the pins are directed in a substantially horizontal manner and the rubber-elastic elements are inserted into lower partial bearing cups and are inhibited by upper partial bearing cups at the exit from the lower partial bearing cups.
