Patent DE-4019642-A1 (DE)
Inventor: FEHLMANN WOLFGANG
IPC: F02M41/12
Filed: 1990-06-20
Abstract: A fuel injection pump for internal combustion engines has an angular position sensor consisting of a stationary sensor part (36) and a mobile part in the form of a sensor wheel (30). In order to determine with the greatest possible accuracy the time that elapses between the beginning of injection and the time at which the pump piston stroke actually begins and also the engine speed during delivery, the stationary sensor part is arranged on a supporting ring (33) which is coupled with the roller ring (18) by a pin (41). The pin is set at approximately 90 DEG  to the pin (45) which actuates the roller ring. The result of the measurement by the angular position sensor is virtually unaffected by self-movements of the roller ring due to forces of reaction during the pump piston stroke.

Abstract: A dimmer circuit for a load circuit having a low-voltage halogen light or lights (NV) and a power transformer (Tr) or power transmitter connected upstream thereof, for variation of the real power taken from an AC voltage supply and emitted to a load circuit (Tr, NV) has: a high-frequency AC voltage generator (20) which emits an output AC voltage (uW) from an essentially smoothed or unsmoothed, rectified low-frequency intermediate circuit voltage (uN) to the load circuit (Tr, NV) and a variable delay switching element or a digital/analog propagation time element, in particular a lowpass filter (PT1) consisting of a variable resistor (R4, R5, P) and a synchronous capacitor (C1) in a series circuit. The circuit arrangement is intended to be designed such that an improved (in particular reduced in size) dimmer circuit permits continuous dimming control between zero and maximum of, in particular, low-voltage halogen lamps. This is achieved according to the invention by providing a synchronous circuit (V5, V7, TH; R16, V13) which is connected on the output side to the delay switching element, to the propagation time element or to the synchronous capacitor (C1) of the lowpass filter (PT1) and, on the input side, is supplied from the rectified intermediate circuit voltage (uN) or the AC voltage supply. <IMAGE>

Inventor: RABIEN PETER
IPC: F02G1/043
Filed: 1990-08-07
Abstract: An exhaust gas-air mixture passes through a cycle. In each cycle a certain fraction of exhaust gas is removed at the point of lowest energy and replaced by fresh air. Integrated counterflow cooling (6) followed by gentle compression, with a small difference between isothermal and adiabatic curves avoids the drawbacks of a purely isothermal process. The valves (11, 12) are on the cold side and combustion takes place in a hot ceramic combustion chamber. The position and nature of the circuit means that a minimun of NOx is generated, with the greatest possible thermodynamic gradient.

Title: Controlled influence on general weather conditions - achieved by pumping large volume of sea water to desert areas
Inventor: LOIDL WALTER
IPC: A01G15/00
Filed: 1990-11-27
Abstract: In order to reduce the effect of global warming large amounts of sea water are pumped into desert areas.
