Title: Apparatus and process for treating contaminated, in particular oily and emulsion-laden materials
Inventor: ERICH EGON DR
IPC: B09C1/02
Filed: 1993-08-21
Abstract: An apparatus for treating contaminated, in particular oily and emulsion-laden, materials and a corresponding treatment process are presented and described. Reliable treatment for contaminated materials is achieved with low expenditure in terms of equipment and high economic efficiency by an apparatus which is characterisd by material feed and removal (1, 2), a sump (6) for receiving the material to be treated, an exchange zone (11b) and a calming zone (11c), a conveyor element transporting the material from the sump (6) through the exchange zone (11b) into the calming zone (11c) and a cleaning medium or an extraction medium or a substance to be absorbed or adsorbed being passed into the material via fluid nozzles (13a, 13b) arranged in the area of the exchange zone (11b) and the laden fluid being removed from the apparatus in the area of the sump (6) through suitable valves (8) or the like and filter elements (8a). In accordance with the process, for this purpose the material to be treated is transported in counter-current through a cleaning medium or an extraction medium or a substance to be absorbed or adsorbed flowing in the opposite direction, the material being transported from a sump (6) by at least one conveying element into an exchange zone (11b) and from there into a calming zone (11c) and the laden fluid being removed from the sump (6). <IMAGE>

Patent DE-4333803-A1 (DE)
Title: Device for preventing liquid from penetrating the measuring cell of a gas analyser
Inventor: KIMMIG LUDWIG DIPL ING
IPC: G01N1/22
Filed: 1993-10-04
Abstract: Sampling systems of gas analysers of instruments for measuring motor vehicle exhaust gas generally contain liquid traps which deposit liquid droplets carried along with the gas flow or, above all when it is cooled, condensate liquid which is pumped off. If, however, a great deal of liquid is transported in the gas flow, the liquid trap can fail and condensate can reach the analysis chamber via the measuring-gas path. According to the invention, this is prevented by connecting a valve in the gas path, which valve is opened in the case of a liquid-free gas flow, and closed in the case of a gas flow loaded with liquid. The invention is usable in instruments for measuring motor vehicle exhaust gas. <IMAGE>

A system (16) measures and delivers a reaction agent to the water (10) in the primary tank (14), mainly of colloid silicon, to emulsify the impurities. A further system (22) has a feed tube (20) to the primary tank (14) for a coagulant, mainly for chitosan. A pump (24) is at the tube (20), downstream of the coagulant feed point, to give ambient air at high pressure. A separator (26) separates air from the water after it has dissolved. A sec. tank (18) gives a water/gas sepn. together with fine bubbles. The impurities are removed (29) from the upper side of the secondary tank (18), together with the fine bubbles floating on the surface, away from the assembly. The clean water is delivered (28) from the secondary tank (18) after the impurities have been skimmed off. USE/ADVANTAGE - The method is for cleaning water supplies where they are delivered from a well, and the like, especially at times of water shortages, The technique cleans the water of light iron and manganese soiling.

Title: System for protecting the occupants of vehicles
Inventor: ITO KEIJI
IPC: B60R21/16
Filed: 1994-09-12
Abstract: A system for protecting the occupants of vehicles is disclosed which, for operating the protection system, has an auxiliary current source which has a lower capacitance than in known systems. As a result, the system according to the invention can be more compact and lightweight in design. The vehicle has a battery which is connected in parallel to two diodes via a key-operated switch. The output current of the diode charges a safety capacitor. The energy discharged from the safety capacitor is fed to an airbag circuit via a switch. The output current from one of the diodes is also fed to the airbag circuit. The switch is controlled by a detection circuit which decides whether the airbag circuit is being fed energy from the safety capacitor or not. A firing device is set in such a way that the airbag can be operated via the switch, the latter being switched on in the case of a deceleration so that the detection of a collision causes power to be supplied.
