Patent DE-4136637-A1 (DE)
Title: Separating melts form e.g. other materials - using continuous equipment to pass melt through passages to drive rotor and filter where two scrapper blades remove and discharge impurities
Inventor: HAEBERLE WILHELM
IPC: B29B17/02
Filed: 1991-11-07
Abstract: Equipment is used to separate materials with different melting pts., and particularly to regenerate plastic packaging or scrap which is coated with metal foil and/or paperboard which can be softened in a plasticator such as a screw press. The equipment concerned consists of e.g. the screw press with attached head which contains a filter fixed between the head and an injector; it separates the plasticated material from the impurities, and the fitlered off dirt etc., is scraped off by blades attached to a rotating tool. ADVANTAGE - The system functions continuously. It absolutely reliably removes the impurities from the filter but without risk of clogging or loss of melt. The scraper is pressed against the filter under constant pressure even if it or the filter is worn. No drive system is needed for the scraper and its speed of rotation can be adjusted to suit the degree to which the filter is fouled up.
Patent DE-4137377-A1 (DE)
Inventor: RISH NIKOLAUS PROF DR
IPC: B01D61/52
Filed: 1991-11-13
Abstract: For the purpose of electrodialytic purification of the electrolyte of an electroplating bath, a pickling bath or the like, the bath fluid (process electrolyte), in order to be continuously regenerated, is passed in a closed circulation through a first chamber (21) of an electrodialysis cell (20). The first chamber (21) has a wall designed as a semipermeable membrane (33) and is immersed within a bath formed by a second larger chamber (22). The second chamber (22) holds an auxiliary electrolyte which is separated from the process electrolyte by the membrane (33). The one chamber (21) or (22) holds the anode (31), and the correspondingly other chamber holds the cathode (32) of an electric DC current source (30). This apparatus enables the electrodialytic regeneration process for the process electrolyte to be operated continuously. To this end, the auxiliary electrolyte is passed in a close circulation through the second chamber (22) which is used as the auxiliary electrolyte bath and holds the first chamber (21). The auxiliary electrolyte used is preferably a carboxylic acid. The auxiliary electrolyte preferably contains a supporting electrolyte. <IMAGE>
Patent DE-4139006-A1 (DE)
IPC: C25D11/02
Filed: 1991-11-27
Abstract: In order to enhance the thickness and wear resistance of oxide-ceramic coatings on barrier-layer metals, a plasmachemical anodic oxidation in a chloride-free electrolyte bath is carried out at a pH from 2 to 8 and constant bath temperature, using a constant current density of at least 1 A/dm<2>, until the voltage settles at a final value. Thus it is possible to generate, on objects made of aluminium or aluminium alloys, an oxide-ceramic coating which consists of corundum, and even on magnesium or titanium, coating thicknesses of up to 150  mu m are achieved.

Title: Air conditioner control unit
Inventor: NOMURA TOORU
IPC: B60H3/00
Filed: 1993-04-13
Abstract: In an air conditioner control unit, the change edges of the sensor output signals are detected by means of the second derivative of output signals of a WO3 sensor or NOx detection. The edge indicates that the sensor is being subjected to diesel exhaust gases. The sensor reactors rapidly to diesel exhaust gases and is not greatly impaired by the effect of wind. Once the edge has been detected, an inlet in the blower (fan) of a motor vehicle is closed and the supply flow of contaminated (polluted) external air is interrupted. A microcomputer with a memory and A/D converter is used to process the sensor signal. In order to balance an insufficient resolution by the A/D converter, the output signals are firstly differentiated in analog form, subsequently amplified and converted into digital signals, and are finally differentiated still further in digital form.
