Patent DE-3434326-A1 (DE)
Title: Method for deriving a clutter-dependent target recognition threshold in a radar system
Inventor: MUELLER THOMAS DR
IPC: G01S7/292
Filed: 1984-09-19
Abstract: The derivation of a target detection threshold as determined by the mean value and variance of measured values using a stored correlation rule is faulty when the amplitude values are previously quantised because mean value and variance are falsified mainly by the lower quantising threshold of the quantiser. According to the methods proposed, either the same error effects are simulated for setting up the stored correlation rule, and a correlation rule already falsified and compensating for the errors in the measured values is stored, or a correction rule taking into consideration the quantisation errors is additionally stored for the measured values of mean value and variance, by means of which corrected values for the mean value and variance are obtained, in accordance with the determination of which a target detection threshold is derived from the correlation rule.

Patent DE-3514643-A1 (DE)
Title: Reflection light barrier
Inventor: SCHIFF ANDREAS DR
IPC: G01V8/14
Filed: 1985-04-23
Abstract: A reflection light barrier is represented and described which has a light barrier transmitter (1) which emits transmitted light pulses, a reflector (2) which reflects the transmitted light pulses, that is to say supplies reflected light pulses, a light barrier receiver (3) which is light-sensitive for the reflected light pulses, and an evaluation circuit (4) connected downstream of the light barrier receiver (3). It is ensured in the reflection light barrier represented that strongly reflecting objects which are located in the beam path do not have the same effect as the reflector (2) at the end of the beam path, specifically owing to the fact that the reflector (2) converts the transmitted light pulses into reflected light pulses with a time delay and the evaluation circuit (4) supplies an output signal corresponding to the reception of reflected light pulses only if the reflected light pulses reach the light barrier receiver (3) after the light barrier transmitter (1) has emitted the transmitted light pulses.

Title: Process and equipment for thermal cleaning of light metal chips contaminated with cutting oils
Inventor: SCHMITZ CHRISTOPH
IPC: C23G5/00
Filed: 1985-05-13
Abstract: In the machining of light metals, in particular with formation of aluminium chips, cutting oils are used for cooling the workpiece and for improving the cutting properties. The chips contaminated with cutting oils have hitherto, before melting down for recovery of the metal, been freed of the contaminants in drum driers. The disadvantage of this process is the poor heat utilisation and the lack of after- treatment of the cutting oil vapours arising. By means of the equipment according to the invention, the process according to the invention allows complete thermal cleaning of the chips in a two-stage process by the hot gas from a melting furnace (16) or a hot-gas generator (22), in the first stage in a flow drier (6) and in the second stage in a fluidising chamber drier (10). The waste gas laden with cutting oil vapours is burned in an after burner (23). The waste heat of the waste gas is utilised in a recuperator (25) for generating hot air. <IMAGE>

Patent DE-3524047-A1 (DE)
Title: Scrubbing liquid and process for separating SO2 and NOx from flue gases of fossil power stations with simultaneous N2O separation
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/34
Filed: 1985-07-05
Abstract: It is known that in the combustion of fossil energy sources, in addition to NO2 and NO, N2O is also formed. This N2O is undesirable in principle since it leads to an enrichment in the stratosphere and the ozone layer is affected. The know processes for decreasing the NOx in the flue gas are primarily orientated to separating out NO, since this NO constitutes over 90% of the NOx. It is also known that, for example, in the selective catalytic reduction of NO using NH3, not only N2 and H2O but also N2O is formed, as a result of which the N2O base content in flue gases is increased. It has now been found that the N2O concentrations of 10-50 ppm in the flue gas, independently of the concentration, can be reduced according to the invention to below 2 ppm by using a scrubbing liquid which contains iron chelate, sodium hydroxide solution, sodium sulphite and sodium sulphate and by addition of reducing agents and/or masking agents, for example preferably dithionite and/or tartaric acid, for maintaining ironII or for reducing ironIII to ironII selectively and/or simultaneously separates out SO2, NOx, NO2, HCl, HF and other, preferably acidic pollutants. The pH of the scrubbing liquid is adjusted to below pH 8, preferably - depending on the necessary efficiency - between 6 and 7.5.
