Title: Procedure and device for cleaning vehicle washing water - comprise adding flocculant and water is agitated to form foam which carries dirt particles to upper outlet while water is drawn from base of chamber
Inventor: NEBEL MAX
IPC: C02F1/24
Filed: 1990-12-04
Abstract: In a new procedure for separating dirt particles from vehicle washing water, the water (5) is treated with a flocculating medium (7) and is mixed with air (11). This mixture is then agitated so that a foam with very fine bubbles is produced, and this foam is separated into clean water and a contaminated foam which contains a greatly increased proportion of dirt particles. USE/ADVANTAGE - Used in automatic vehicle washing systems. Dirt particles are effectively removed from the waste water so that the waste water can be re-used as often as required.

IPC: G01B9/02
Filed: 1992-07-03
Abstract: The invention relates to a multi-arm interferometer, in which the measurement information is obtained from the interference of two beams (1, 2) of different frequency. According to the invention, there is provided for each beam (1, 2) a source location for generating component beams which are assigned to one another in conjunction with a direction of propagation which is the same at least in sections, and of which, after it has traversed an interferometer arm, each component beam of the one frequency has a common beam path with the assigned component beam of the other frequency so as to produce interference. A compact design with low dimensions is realised in which, while retaining the heterodyne measurement principle, frequency fluctuations in the laser light source and changes in the environmental conditions leave the measurement result obtained unaffected as far as possible, and non-linear errors are ruled out. <IMAGE>
