Abstract: Bei der Elektrolyse einer wässrigen Alkalichlorid-Lösung entsteht im Anodenraum der Elektrolysezelle ein Gemisch von Anolyt und Wasserdampf-gesättigtem gasförmigen Chlor. Erfindungsgemäß arbeitet man unter einem Druck von mindestens 8 bar. Zur Aufarbeitung wird zunächst Anolyt und Wasserdampf-gesättigtes gasförmiges Chlor in einem Abscheider (2) voneinander getrennt. Dann wird das Wasserdampf-gesättigte gasförmige Chlor unter einem Druck von mindestens 8 bar durch Abkühlung in einem Kondensator (6) verflüssigt. Bei dieser Abkühlung fällt ein Kondensat an, das aus einer flüssigen, wassergesättigten Chlorphase (23) und einer flüssigen, chlorgesättigten Wasserphase (22A) besteht. Die Temperatur dieses Kondensats soll bei der Abkühlung nicht unter 28°C absinken. Schließlich trennt man die leichte Wasserphase (22A) von der spezifisch schwereren Chlorphase (23) ab.

Abstract: The drives (34,34') of a vehicle are each driven by a pump (18) and motor (22) of a hydrostatic transmission (23). A servo-system (20) associated with each pump (18) is adapted to be controlled by a steering arrangement (35,36) for selectively rotating the drives (34,34') relative to each other. An interlock valve (43,44) is associated with each steering arrangement to stop the drives (34,34') of the vehicle when steering pedals (37,38) thereof are both depressed into certain positions (N,R) of operation. Thus, the operator of the vehicle is prevented from placing the vehicle in an unwanted mode of operation, such as in reverse, when the operator desires another mode of operation, such as braking of the vehicle.

Abstract: In a method of descaling the surface of metallic materials by means of an acid pickling solution, the surface of the material is briefly contacted with a mixture of orthophosphoric and diphosphoric acid at a temperature of about 90 to 300 DEG C, in order to avoid or reduce losses of material and to improve the surface quality. Depending on the diphosphoric acid concentration in the pickling solution and on the chosen temperature, treatment times of 5 to 20 seconds are intended. The method of the invention is mainly suitable for descaling the surfaces of beryllium-containing alloys, in particular beryllium-containing alloys of copper and nickel, or of the strips or finished parts produced from them.

Abstract: The rate of filtration of a coal liquid slurry is increased by adding polyisobutylene and an alcohol containing 2 to 10 carbon atoms to the slurry prior to filtration or by adding the alcohol to the slurry and washing a precoat cake of filter aid with an oil solution of polyisobutylene prior to filtration. Although the polyisobutylene and the alcohol each provides a filtration rate improving effect when used alone, a synergistic improvement in filtration rate is achieved by their combined use.
