Title: Rocket propulsion by annular and revolving conc. laser beams - involves generation of thrust by reaction of beams radiated with unequal energy density due to magnetic rotation
Inventor: RASBACH KLAUS
IPC: B64G1/40
Filed: 1992-07-07
Abstract: The annular beam is generated and radiated by a ring laser while a second laser emits a sharply conc. beam which is positioned and deflected within the annular beam. On account of its revolution in strong magnetic fields the pointed beam has a higher energy density than the surrounding radiation. The difference in energy densities at the boundary between the two beams gives rise to a thrust which affords sufficient power for the propulsion of a rocket. ADVANTAGE - Practical photon-induced propulsion is achievable at a tolerable level of energy consumption.

Patent DE-4234456-A1 (DE)
Title: Antilocking braking control method with cornering correction - monitoring differences between actual steering and control settings for correction factor for braking
Inventor: DODEN BEREND-WILHELM DIPL ING
IPC: B60T8/1755
Filed: 1992-10-13
Abstract: Dynamic sensors (2,3,3) on the vehicle measure the actual cornering settings of the vehicle and compare them with the settings of the steering controls. This produces a slip factor which is used to correct the ABS control for a more stable braking effect while cornering. The operating point on the brake control plot is shifted towards smaller grip factors, i.e. to reduce the braking effect and increase the brake modulation. The vehicle speed, lateral acceleration and steering setting provide the main parameters. The rate of change of the correction factor is also computed in the control unit (1) for a more responsive correction control. ADVANTAGE - Improved cornering stability, safer cornering control.

Title: Current source circuit
Inventor: DRUSENTHAL ULLRICH DIPL ING
IPC: G05F3/26
Filed: 1993-08-05
Abstract: Known current source circuits are for the most part not very suitable for low supply voltages and there is a lasting influence on the output current stability in the case of a broad supply voltage range owing to the early effect or channel length modulation. To overcome these disadvantages, according to the invention a load resistor connected in the output circuit of a current mirror supplies an actual value for an amplifier which operates as a comparator, is part of a control loop and controls an actuator, which regulates the input current of the current mirror, in accordance with the control error produced by this amplifier.

Title: Defrosting coolant vaporiser or refrigerator installation
Inventor: REFLE JOSEF
IPC: F25B47/02
Filed: 1994-03-23
Abstract: A method for defrosting the pipework and attached baffle plate system of a vaporiser unit (1) forming part of a refrigerator installation employs the relatively hot refrigerant vapour delivered at the high-pressure side of the compressor (2) during normal operation in a circuit (4) which bypasses the condenser (19) and enters the sealed ends of the vaporiser main pipe network (27,28) as a warm gas via capillary conduits.
