Abstract: This invention relates to a hydraulic damper arranged between a vehicle chassis and a wheel axle for use in attenuating a vibration transmitted from a road surface. A leaf valve and a main valve are provided at an inner seat and an outer seat having different heights to each other arranged at outlet ports of a piston in such a way as they may be opened or closed, the leaf valve is supported at its base end by a stopper provided with a tapered or curved surface at is upper surface. The main valve is arranged in such a way as it may be floated up and down in opposition to the outer seat. A load of the main valve is set only with an inertia of a spring, so that an attenuation force can be stabilized, and the leaf valve is supported by the tapered or curved surface of the stopper when flexed, resulting in that no cracks are generated.

Abstract: A process for producing a composite finger-touch key with superior fastness, in which the key top layer is chemically bonded to the key base piece even when a silicone resin is employed for the key base piece, which process is characterized by treating the surface of the key base piece to be bonded with the key top layer by exposing to a UV-irradiation or to a plasma discharge in order to subject the surface to a chemical activation, applying then a coupling agent based on silane, such as aminopropyl triethoxysilane, vinyl triethoxysilane and mercaptopropyl trimethoxysilane, to the so-treated surface of the key base piece, providing thereon with a layer of a resin curable by UV-irradiation or by heating, such as those based on, for example, acrylic, epoxy or silicone resin, of an adequate configuration and exposing the resin layer to a UV-irradiation or a heating to cause curing of the resin layer.

Abstract: A spindle sleeve (4) is provided for the rotary operation in a tool changing device on a hand-operated machine tool, especially a drill hammer for optional operation with a hammer drill or with another tool. To make rapid tool change possible with a simple design, a locking body (7), which co-rotates with the spindle sleeve (4), is mounted in at least one perforation (6) of the spindle sleeve (4). An adapter (14), on which the corresponding tool can be fixed, can be axially inserted into the spindle sleeve (4) with a guide surface (22, 23), and has depressions (13) for the locking bodies (7) for nonrotatable and axially nondisplaceable connection to the spindle sleeve (4). An outer sleeve (8), which blocks the locking bodies (7) in the depressions (13) in a locking position and radially releases them in its release position, is displaceably arranged on the spindle sleeve (4).

Abstract: The present invention pertains to a multiaxial manipulator (1), in which the supply lines (9, 10) for the tool (7) and for the manipulator drives (8) are led in separate bundles of lines and are connected separately. The supply lines (9, 10), led in from the outside, are connected to the relatively stationary base (2) of the manipulator (1), wherein at least the supply lines (10) for the tool (7) are then led inside the base (2) to the moving carousel (3). The supply lines (10) again exit to the outside at the carousel (3) and are then led along the moving manipulator parts (4, 5, 6) to the tool (7). The supply lines (9) for the manipulator drives (8) can also be led in a similar manner on the inside through the base (2) and then on the outside, along the manipulator parts (4, 5, 6).

Abstract: A rubber bearing for the central pin of a leaf spring suspension in a motor vehicle includes a housing split in an axial plane and of a rubber bushing (1), which is arranged on the pin with radial pretension and includes two half shells (3, 4), which are axially fixed on the pin by at least one radially engaging tongue-and-groove assembly (8, 9), whose abutting surfaces, which are located opposite each other in the assembled state, are at a distance from one another peripherally in the preassembled state. The half shells (3, 4) of the rubber bushing (1) in this rubber bearing are connected to one another at their ends by flexible webs (5) and have recesses (12), which accommodate the webs (5) folding in during the radial compression.

Abstract: A motion indicating device used especially to monitor the movement of sheets of paper, which are moved via conveyor paths. A scanning device has a rotatably mounted scanning member, which lies on the scannable surfaces of the moving sheet of paper and is set into rotation by same, and which is provided with signal elements, which generate motion signals in a stationary electronic signal transmitter by their rotary movements. The scanning member is a ball (8) with uneven weight distribution or a hollow ball (81, 82). The ball is guided freely rotatably in a guide cage (7) and has at least one signal element. A signal transmitter is arranged on a side located diametrically opposite the contact point (19) of the ball (8) and is directed in this plane of rotation toward the ball (8).

Abstract: The center has, on its cylindrical wall, adjacent longitudinal rows of slots (3) which are elongated lengthwise, the slots of one row being staggered--generally by half a pitch--with respect to those of the contiguous rows, so that the longitudinal edges of each slot (3) can be brought closer together in the intermediate zone, allowing a substantially uniform reduction in the transverse section of the center when the cylindrical wall of the center is subjected to centripetal pressure under the action of the turns of the wound yarn; an extension (5) projecting into the slot (3) constitutes a spacing element to limit the amount by which the longitudinal edges are brought closer together in their intermediate zone.

Abstract: A laser spectrometer suitable for detecting gas components in a test sample in the ultraviolet range. The measuring laser radiation (2) is sent to a nonlinear crystal (20, 40, 41), which increases the nominal laser frequency to the frequency that corresponds to the absorption wavelength of the measured gas. Tripling of the frequency takes place either after passage of the radiation through a single nonlinear crystal (20), or by mixing a frequency-doubled laser beam with the measuring laser radiation (2) in a common, second nonlinear crystal (41).

Abstract: A mechanised ballistic target presents a hinged target plate which is knocked down out of sight when hit by a bullet and the shock of the bullet impact on the plate is absorbed pneumatically by a rubber suction cup which the plate strikes; the suction cup has an air leakage passage defined by a capillary tube which sets a time delay before the suction cup releases the target plate to allow a spring to return the target plate to a ready position for the next shot.
