Abstract: A two-wheeled vehicle has a frame having a wheel support member at the rear of the frame. A rear wheel is spring-supported at the wheel support member. A first lever is rotatably mounted by a first rotary bearing at the frame and by a second rotary bearing at the wheel support member. A second lever is rotatably mounted at an upper end portion of the wheel support member and the frame, respectively. A spring element is rotatably mounted at the frame and/or the wheel support member and/or the first lever and/or the second lever, respectively. The second rotary bearing is positioned above the axle of the rear wheel and is positioned at the wheel support member, when viewed from the axle of the rear wheel toward a front end of the vehicle, at a distance of between 0.045 to 0.8 times the length of the wheel support member from the axis of the rear wheel.

Abstract: A recorded image frame is distorted on the printing plate when image information or image data from a computer is recorded in the form of band strips, with a plurality of image elements dotted on each widthwise dotted line of the band, on a printing plate wound over a drum. The present invention permits an undistorted recording on the printing plate by an arrangement which includes a printing plate wound around a drum in the form of a right circular cylinder, an exposing assembly to record image information in the form of a band strip on the printing plate by means of light beam, a moving mechanism to move the exposing assembly in relation to the drum in the direction of the drum axis--by one band width per revolution of the drum--and a circuit to generate and incline distortion offsetting signal in a sawtoothed pattern having the cycle synchronized with that of the rotation of the drum with the initial writing position on the band as starting point.

Abstract: A height adjustable false bottom for multi-purpose pools. The apparatus has a device for adjusting the height of the false bottom, where a plurality of supporting legs, which are pivotable and have a variable length, are used for the height adjustment. The supporting legs are preferably formed as rotatable spindle drives.

Abstract: A sleeve-type rubber shock absorber with hydraulic damping for mounts in motor vehicles includes an inner mounting sleeve (1), an outer mounting sleeve (2) surrounding same at a radially spaced location, at least one elastomer body (3), which is adheringly arranged between the two mounting sleeves and forms at least one chamber (4) filled with hydraulic damping agent. A cap (5) sealingly closes the sleeve-type rubber shock absorber, forming a second chamber (6). A channel plate (7) is provided which contains a throttle channel (7.1) connecting the chambers (4 and 6), wherein the outer bearing sleeve (2) has at least two different external diameters, of which the mainly radially loaded area of the smaller diameter is inserted into the motor vehicle component (8). At least two stop buffers (9) are arranged distributed over the circumference and are provided on the corresponding area of the inner mounting sleeve (1).

Abstract: A locking device for a positional fixing of a displaceable adjusting element for a selector shaft of a mechanical gear transmission of a motor vehicle comprising an outer housing (2) and, displaceably guided therein, a locking pin (8) loaded at one end by a compression spring (14) which is supported on a bottom (15) and causes a stroke movement of the locking pin (8), the selector shaft comprising a recess which is engaged by a spherical locking element (11) retained in an end of the locking pin (8) facing away from the compression spring, the locking device further comprising an electric switching element (25) which can be activated by an actuating element arranged on the locking pin (8), characterized in that the actuating element is an compensation element (16a to 16d).

Abstract: The present invention relates to a process for the production of a dense Si.sub.3 N.sub.4 material by normal pressure sintering of mouldings which have been manufactured from mixtures of Si.sub.3 N.sub.4 powders and sintering additives without being embedded in a powder packing and are sintered at temperatures of 1775.degree. C.+-. 75.degree. C.

Abstract: A ball joint for chassis parts in motor vehicles is described, in which a hinge pin 1 with a spherical part 2 is mounted in a housing 3 by a bearing box 4. The hinge pin is led through an opening 6 out of the housing 3. The housing 3 is sealed by a lid 7, on the opposite side. In this case, the housing is placed in a rigid external bushing 10 with an elastomer sleeve 9 surrounding the housing. Radial surfaces on the housing 3, as well as on the external bushing 10, limit the axial movement of the housing 3 with respect to the external bushing. The radial surfaces of the housing 3 are formed by the two flat sides of a collecting plate 15, which can be firmly connected to the housing 3 first in the assembly of the joint. The collecting plate 15 engages with an axial moving space between arranged radial surfaces of the external bushing 10.

Abstract: The radially and axially load-bearing rotary sliding friction bearing for chassis parts in motor vehicles includes a rigid inner bushing (1) and an outer bushing (2), which is rotatable relative to it and is arranged in an elastomeric body (3) that adheres to it. Both bushings have, at least on one axially outer end, axial bearing surfaces at one radially directed flange projection (6, 7) each, wherein the flange projection associated with the outer bushing (2) is provided on an annular axial bearing on a sliding disk (7) and on a support ring (8) pressed onto the adjacent tubular end of the outer bushing (2). The sliding disk and the clamping ring are connected to one another by an elastomeric material in an adhering manner.

Abstract: Process for the production of a short-prismatic aluminum hydroxide by decomposing a supersaturated sodium aluminate liquor. The product can be used as a pigment and filler in the paper industry, as a flame-retardant filler in plastics and as a white pigment in paints and enamels.

Abstract: To eliminate a holding frame for a starting wire (20) outside of an elongd discharge vessel (1), the starting wire (20) is directly connected to one of the electrode leads (4, 5), typically niobium tubes, by a bimetal strip (21) which is, preferably, bent in stepped form or Z shape. Under cold conditions, the strip or wire (20) is in engagement with the outside of the discharge vessel (1) to assist in starting, due to its electrical connection via the bimetal strip (21) with one of the electrodes; upon heating of the lamp, the bimetal strip (21) will lift the wire (20) off engagement with the discharge vessel (1) and thus prevent deterioration thereof.

Abstract: To mount a discharge vessel (8) within an elongated bulb or envelope (2) le permitting thermal expansion of the discharge vessel (8) and yet maintaining the discharge vessel, free from vibration, within the tube in alignment with the longitudinal axis thereof, a flat leaf spring element (15, 15') (FIG. 2 ) is secured to a holder structure (5; 6a, 6b, 12) secured in the bulb and the respective electrode current connections (10a, 10b, 25a, 25b) to the discharge vessel, the flat leaf spring element being so located in the bulb that its major plane is oriented essentially perpendicularly to the longitudinal axis of the lamp.

Abstract: To retain an arc tube (6, 16) in precise position with respect to an opti system (R) within an outer envelope (2, 12), the arc tube is retained at both ends by spiral springs (23) which have a cylindrical portion fitted in a sleeve-like current supply (7, 17) to the arc tube and having a conically expanding portion (25), terminating in an end portion (26) which is welded to a central guide pin (27) fitted and movable within the cylindrical portion (24) of the spring. The guide pin (27) can form part of an internal current supply (FIG. 3: 19) or be secured to an internal current supply lead (FIGS. 1, 2: 9).

Abstract: A stepping gear includes an output member attached to a wheel which is provided with a number of rollers on both faces thereof. In driving contact with these rollers is a pair of cam members having contours which allow for driving in the forward direction as well as a standstill or dwell phase. In addition, reverse movement of the wheel is made possible by providing an undercut in one of the cams coupled with a superelevation on the other of the two cams. Form locking engagement between the cams and the rollers is maintained during the forward driving phase, and the standstill and return phases as well.
