Abstract: A protective covering for the piston rod of a telescoping spring element which includes a gas pressure cylinder and a piston rod. For protecting the piston rod during painting of the motor vehicle, the gas pressure cylinder is surrounded with a protective covering of sponge rubber which surrounds in a fluid-tight manner the cylinder casing and a sealing disk arranged at the free end of the piston rod. For the rapid removal of the protective covering after the painting operation, it is provided with a radially projecting tearing extension which has at its two base edges one cross-sectional reduction each formed by a longitudinal groove. The protective covering is longitudinally divided by these cross-sectional reductions, when tearing the tearing extension radially outwardly or in the longitudinal direction of the gas pressure cylinder, so that as a result thereof the protective covering then only has to be pulled off the gas pressure cylinder.

Abstract: Electrically operated valve for liquid or gaseous media, suitable for internal combustion engines, possessing an electrically-activated actuating element with a short actuating displacement, this actuating element acting on a control valve, and possessing a nozzle element which unblocks a nozzle when a defined pressure is present in the supply line. The actuating element is connected to an actuating-element base and is pressed, by means of an actuating-element spring, against the control-valve plate of the control valve, this control-valve plate being pressed, by a stronger control-valve spring, against a fixed reference plane. In order to compensate for changes in the length of the actuating element, resulting from mechanical forces and/or from temperature changes, a collect-type clamping device is provided, which is subjected to the pressure of the medium and clamps the actuating element while it is being operated.

Abstract: A pressure-tight vessel for the storage of hydrogen in a metal matrix body and in which a matrix body is arranged in a tube preferably made of aluminum, the outside diameter of the matrix body before activation is less than the inside diameter of the vessel, and in which discs are provided filling the tube cross-section, which discs rest against the end faces of the matrix body and are displaceable axially outwards against resistance within the tube, as a result of which it becomes possible for the matrix body to expand in the axial direction. For a faster absorption and emission of hydrogen, the matrix body is preferably provided with a central extraction tube which is guided through the discs. Any deformation of the vessel as a result of changes in volume of the matrix body is avoided by this construction.

A locking clutch which operatively connects a half-shaft bevel gear meshing with the differential bevel gear to the differential gear housing, and which lies between an axial abutment immovable relative to the differential gear housing and an axially movable pressure disc, is engaged by means of a pin type pressure member which is adapted to be operated, with the aid of a rolling contact bearing, by an actuator of the axial piston-cylinder type. A half-shaft part is rotationally fixed to the half-shaft bevel gear and passes through the journal.

Abstract: A control arrangement for a clutch and/or brake of a press, with the control arrangement including at least one of a clutch cylinder piston unit and a brake cylinder piston unit which opposes braking forces until a desired rotational speed is reached. The cylinder-piston units may be operationally controlled by at least one valve before the desired rotational speed is reached. The control arrangement is driven by at least two different pressures, with one of the pressures being at least approximately equal to a maximum clutch pressure or at least approximately equal to a pressure release, and the other pressure being a partial pressure which lies above a minimum response pressure of the clutch or below a counter pressure which triggers a minimal response pressure of the brake.
