Patent DE-3330509-C1 (DE)
Inventor: BURTSCHER HEINZ DR
IPC: F23N5/00
Filed: 1983-08-24
Granted: 1985-05-23
Abstract: 1. Method for regulating combustion processes, in which at least part of the combustion waste gas is moved passed an ultraviolet lamp, in which the quantity of the positive and/or negative charge carriers produced by the radiation of the ultraviolet lamp or the current produced by these charges is measured and in which the oxygen-fuel mixing ratio is regulated as a function of the measured value or values obtained, characterized in that the ultraviolet lamp used is of the type which, for ionizing suspended particles occurring in the combustion waste gas, supplies ultraviolet light with a photon energy, which essentially corresponds to that of a low pressure mercury vapour lamp and that prior to its irradiation a photoelectrically inert gas is supplied to said waste gas part in such a way that both gases flow in laminar form and parallel to one another through the area alongside the ultraviolet lamp and the flow of photoelectrically inert gas isolates the contamination-sensitive ultraviolet lamp from the exhaust gas flow.

Title: Device for the load-dependent control of an exhaust gas recirculation valve
Inventor: BLUMENSAAT KLAUS DIPL-ING
IPC: F02M26/55
Filed: 1986-06-11
Granted: 1987-06-19
Abstract: A device is described for the load-dependent control of an exhaust gas recirculation valve, which is arranged in the exhaust gas recirculation line of a diesel internal combustion engine. The device has a pressure converter, which picks up a vacuum signal, modulated according to the position of the adjusting lever of the injection pump of the internal combustion engine, and a vacuum signal generated by a vacuum pump and, as a function of these vacuum signals generates a control vacuum for actuation of the exhaust gas recirculation valve. In order, in a supercharged diesel internal combustion engine, to ensure an optimum adaptation of the exhaust gas recirculation rate to the quantity of fuel injected at any one time, the charge pressure of the internal combustion engine is admitted to the third control chamber of the pressure converter.

Title: Device for repelling or driving away rodents living in the ground
Inventor: DEHM GEBHARD
IPC: F03D9/00
Filed: 1986-07-19
Granted: 1987-05-21
Abstract: A device for repelling or driving away rodents living in the ground such as voles, moles or the like, works by means of noises passed into the ground. These noises are generated by a rotor which is driven by means of wind or solar energy and is arranged above the ground and which has at least one noise generator arranged at its circumference and an oscillating bar which reaches into the ground, is surrounded by a jacket tube and is set in oscillation by the noise generators on rotation of the rotor. This produces noises of varying intensity and at varying intervals, which are particularly effective in repelling or driving away the aforementioned rodents and prevent the risk of the animals becoming accustomed to these noises.

Patent DE-3940834-C1 (DE)
Title: Machine safety monitor preventing unwanted running - has two different frequency generators at separate ends of safety current circuit controlling power relays
IPC: E21F17/18
Filed: 1989-12-11
Granted: 1991-08-01
Abstract: A safety circuit (4) that can be manually broken by strategically placed switches (2,3) connects two remote oscillators (5,7) to a safety station (10) via transfer elements (11,12).  The two oscillators (5,7) generate different frequencies which are mixed and filtered at the safety station (10).  The resultant frequency is used to control the action of the power relays. If a manual switch (2,3) is activated or damage occurs to the safety circuit (4) the subsequent loss of one oscillator frequency changes the resultant frequency at the safety station (10), initiating immediate removal of supply current by releasing the power relays. USE/ADVANTAGE - Safety monitoring circuit (1) controlling action of power relays supplying current to heavy industrial machinery. Guarantees immediate response to intended or emergency opening of safety circuit.  High operational safety at minimal costs.
