An actuating device for applying actuating forces in a friction clutch device for engaging and disengaging a friction clutch assembly of the friction clutch device. The torque transmission device comprises the actuating device for transmission of torque between a drive unit and a transmission which also includes the friction clutch device. A method for installing a torque transmission device of this type. Various aspects relate to setting of a pre-load on a bearing of the actuating device, setting an over-dead-point configuration for a compensation spring associated with at least one rotary member of the actuating device, setting a rotation movement range for the rotary member and/or an axial movement range for an actuating element which can be displaced axially by rotation movement imparted to the rotary member, and producing either a normally engaged or disengaged characteristic in a normally-engaged or normally-disengaged friction clutch assembly with the compensation spring.

A master cylinder for a hydraulically actuated clutch or brake system in a motor vehicle includes a piston in a housing, the piston being axially movable in the housing by a piston rod. The piston rod has a ball-shaped head, at least certain areas of which are surrounded by first and second shell-like support elements which form a ball socket, so that the piston and the piston rod are connected to each other essentially without play, but are still free to swivel with respect to each other. The support elements are arranged at least in part inside a piston shaft sleeve, against which these elements may be supported when forces introduced via the piston rod act upon them. The first support element has a hemispherical shell to enclose half of the ball-shaped head. The other side of the ball-shaped head, except for a certain clearance required for swiveling, is surrounded by a support element with a spherical-segment-shaped ring, through the opening in which the piston rod passes.

A cleaning apparatus for optical or magneto-optical storage disks includes a first rectangular part having four lateral edges and a raised interior, the interior having at least three troughs for holding utensils for cleaning the optical or magneto-optical storage disks; a second rectangular part having four lateral edges, an interior which is shaped complementary to the interior of the first rectangular part, and a border which runs completely along its four lateral edges for enclosing a disk cassette of a magneto-optical or optical storage disk inserted for cleaning; and a back strap for connecting the two parts to each other such that the two parts can be folded together, similarly to a book, and locked along their lateral edges. The second part further includes a disk bearing which, when the storage disk is inserted, raises the storage disk inside the disk cassette to such an extent that the storage disk is rotatable without friction. A locking device is provided on the interior of the second part for keeping a shutter of the disk cassette open. The interiors of the first and second parts, together with the troughs, the edge beads, the locking device, the disk bearing, and the border are deep-drawn from plastics film.

A pressure cylinder for a hydraulic actuation device in motor vehicles includes a housing (1) with an internal cylinder (2,3). A piston (6) is displaceable in the internal cylinder for forming a pressure space (12) for a hydraulic fluid. The piston includes a hemispherical socket (10) in an indentation (9). A spring (18) is arranged in the pressure space (12), and a tappet (7) is connected by a transmission part with a hemispherical cap (8). The tappet (7) is in a frictional and swivelable engagement in the socket (10) in an indentation (9) by the force of the spring (18). The piston is a deep-drawn, cup-shaped part and includes a filling piece (13) in the interior of the piston (6). An annular space (15) is disposed at a piston surface (14) facing toward the pressure space (12). The annular space (15) is for receiving the spring (18) in a compressed state when the piston (6) is in a top dead center position.

A clutch-release mechanism for actuating the friction clutch of a motor vehicle, installed concentrically around a guide sleeve, includes a release bearing with an inner ring and an outer ring as well as a sliding sleeve. The inner ring is in working contact with a release spring of the friction clutch and the outer ring is in working contact with the sliding sleeve by way of a sliding surface, and the release mechanism has both a first device for compensating for a tilt of the center axis of the friction clutch with respect to the center axis of the guide sleeve and/or for a wobbling eccentricity of the release spring, and a second device for compensating for an offset between the above-mentioned center axes. The first device consists of a modified raceway for the balls, where the race has both a first race radius and a second race radius to form a surface in the form of a spherical segment, where differences between the angles of the release spring and of the release bearing are compensated. Because the raceway can be produced in any case with high precision in the outer ring and because the rolling contact of the parts is lubricated with grease and protected from the outside environment by seals, no additional components are required for the release mechanism, and there are no additional friction points to be lubricated and sealed.

In order to provide a power recovery plant comprising a gas turbine with a turbine wheel and a generator with a rotor driven by the turbine wheel, in which the known bearing problems are diminished or even cease, it is suggested that the turbine and the generator be combined in a plant housing to form one unit, that the turbine wheel and the rotor form a rotor unit rotating as a whole and that the rotor unit be rotatably mounted in the plant housing by magnetic bearing units in a non-contact manner.

A cleaning composite for optical and magneto-optical storage disks includes a rectangular strip of a textile or fabric cloth composed of a material capable of absorbing a cleaning liquid; and a rectangularly shaped plastic film; wherein the strip of the textile or fabric cloth and the plastics film are connected to one another along opposite narrow sides. Preferably the strip and the plastics film have the same size. The strip includes a fluff-free clean-room material produced from filament yarn. The strip and the plastics film are thermally bonded to one another along their narrow sides or are adhesively bonded to one another by means of a self-adhesive tape along adhesive strips along their narrow sides.

Disclosed is a process and apparatus for measuring, in a continuous and contact-free manner, the thickness of a layer applied to a support. The apparatus includes a measuring apparatus which comprises a corona and a first electrostatic voltmeter positioned downstream of the corona in the direction of travel of the layer being measured. The process includes the steps of passing the layer under the apparatus, charging the layer in a contact-free manner, and measuring the level of the charging voltage.

The light-sensitive layer of a printing plate is charged to a given surface potential which is measured by means of a stationary or moving potential detector. The potential ratio, which changes during the exposure, is continuously compared with a given set value, and the exposure is terminated when the changing potential ratio is in agreement with the given set value. The measurement of the surface potential and of the potential ratio is carried out in a bright area of the light-sensitive layer, which area is located outside the area of the latent electrostatic image.The potential detector may be connected via a signal converter and an amplifier to a microprocessor control which actuates a shutter via a digital output. In the microprocessor, a program for controlling a corona electrode and a developing electrode is stored, which program actuates the corona control and the developing electrode control via a digital/analog output and high-voltage amplifiers.
