Abstract: A brake system for automotive vehicles includes a pressure generator to which wheel brake cylinders associated with the individual vehicle wheels are connected by way of hydraulic connections. Actuator units including a cylinder-and-piston assembly and an actuator are inserted into the hydraulic connections. The actuator units permit shutting off the hydraulic connections.

Abstract: A method for the hydrodechlorination of a reaction gas primarily composed of chlorinated hydrocarbons is carried out sequentially. A first step is advantageously carried out in a tubular reactor filled with catalyst and cooled externally, to maintain a temperature within a preferred range of 80.degree. to 230.degree. C. and a radial temperature difference of not more than 40.degree. C. Hydrogen is added to the tubular reactor with a hydrogen excess in a preferred range of 1.1 to 1.5 relative to the reaction gas, based on the stoichiometric consumption. The catalyst is present in a catalyst loading in a preferred range of 0.1 to 1.5 v/vh based on the volume of reaction gas. A fixed bed reactor is advantageously used for a second step, optimally connected in straight transit with the output of the reactor of the first step. The full-space reactor is maintained at a temperature within a preferred range of 200.degree. to 300.degree. C.

C., where the quantity of aqueous salt solution passed into the washing zone per Nm.sup.3 exhaust gas flowing through the washing zone is 0.1 to 10 liters. The exhaust gas coming from the penultimate washing zone has a temperature in the range from 30.degree. to 80.degree. C., is saturated with steam for 90 to 100%, and does not contain more than 50% by weight of the dust content of the exhaust gas before the same enters the penultimate washing stage.

Abstract: A new hydrodehalogenation catalyst, as well as to its use for the hydrodechlorination of chlorinated hydrocarbons. The hydrodehalogenation catalyst, which converts halogenated hydrocarbons completely under mild conditions, has a considerably longer lifetime than do known catalysts and can be regenerated. In a method of hydrogenating dechlorination the catalyst works preferably under mild reaction conditions, with lifetimes of at least 2,500 hours and leads to reaction products, which can readily be used economically and thermally without further purification. The catalyst is a palladium aluminosilicate support catalyst, which is free of chlorinated compounds, has a palladium content of 0.5 to 8% by weight and a silica content of 1 to 50% by weight. The palladium concentration over the cross section of the support passes through a maximum in the region 50 to 250 .mu.m below the outer surface of the support, the maximum palladium concentration is 1.5 to 7 times the average palladium concentration.

An electronic sensor is provided for detecting the relative movement between the pressure rod and the booster piston, the output signals of which are capable to influence the excitation of the auxiliary pressure source. This will permit the brake force boosting, if need be, to be effected independently of actuation forces put in manually, with anti-locking control/traction slip control functions being readily exercisable at any time.
