Abstract: A cartridge (1) comprises a cartridge case (2), which is closed at its rear end and contains a propellant charge (3) and a primer (7). The tip portion of the cartridge case defines a socket (4), which accommodates a full-bore projectile (5). The tip portion (2b), terminates adjacent to the nose of the projectile in an end face that is normal to the axis of the cartridge. That tip portion has an outside peripheral surface, which tapers with a substantially concave contour toward said forward end face. To provide a cartridge (1) which can easily be manufactured and can reliably be fired and can be gas-tightly inserted into the chamber of the firearm, the tip portion (2b) is formed in its rear end portion with a peripheral annular groove (6), which is open to the interior of the cartridge case and which contains the primer (7).

Abstract: The flywheel elements are connected to one another in drive terms via a spring mounting, an abutment of which is movable relative to the associated flywheel element against the resistance of a second spring mounting and a non-positive coupling arranged parallel to the second spring mounting. Furthermore, a second non-positive coupling, subject to play, is connected between the flywheel elements and is limited resiliently in at least one direction.

Abstract: In an antilocking braking system, a pressure modulator is provided for the control of pressure reduction and pressure build-up phases, wherein a drive pressure space of this modulator is placed under a pressure control to move a modulator piston into an end position associated with a minimum volume of a work chamber, which forms a section of the master brake line. In this end position, a spring-loaded inlet valve, connected between the work chamber of the pressure modulator and the brake booster of the brake system, is held in its open position by a tappet. As a result of pressure release in the drive pressure space, the modulator piston is displaced in the direction of its end position associated with a maximum volume of the work chamber, so that brake fluid can flow back into the work chamber from one or more wheel brakes connected to this work chamber.

Abstract: A fluid friction coupling or clutch unit is disclosed. The coupling includes a housing which is substantially filled with a viscous liquid. The housing comprises inner and outer parts which are concentrically disposed and rotate about an axis. The fluid friction coupling also includes mutually interleaved inner and outer plates within the housing, the inner plates being coupled to rotate with the inner part of the housing and outer plates being coupled to rotate with the outer part of the housing. The individual inner and outer plates are separated from each other and are axially displaceable so as to vary the size of the gap between them. Annular disc springs are disposed within the gaps between the plates. The annular disc springs are shaped as truncated cones. They act to spread the plates apart. In a preferred embodiment, the fluid friction coupling also includes a pressure body connected to the inner and outer plates.

Abstract: A fuel tank for vehicles is constructed so that any disturbing generation of noise in the fuel tank due to swashing fuel, particularly during acceleration and deceleration, is prevented. For this purpose wall sections of the fuel tank are equipped internally with a structured surface forming stabilization chambers.At the fuel-free regions of these walls sections, the swashing wave front of the fuel is dissolved over a large area, by the surface structure, into a plurality of wave sections which are distributed and diverted, whereby fuel movements which customarily generate swashing noises are effectively attenuated.

Abstract: For obtaining a permanent decorative high-grade fixing of the inner roof covering in a motor vehicle, an approximately U-shaped retaining rail is used whose two legs terminate each in a lip, of which one is bent under interposition of a film hinge--receiving the ceiling material by welding operation--within the area of the film hinge in the direction of a flange-receiving opening extending between the two legs. The flange-receiving opening serves during the fastening of the thus-pre-assembled roof covering for being mounted over a roof-side flange.

Abstract: A regulation for a gas engine with a rotational speed probe for the crankshaft rotational speed, with a rotational speed-load-ignition angle-performance graph memory read out during each crankshaft rotation, with an ignition pulse generator controlled by the performance graph memory, with a lambda-probe, with a load probe, with a vacuum-controlled gas pressure adjusting device for the propulsion gas and with a flow-mixing device for the propulsion gas and the air. The invention provides a regulation for a gas engine which offers a full utilization of the possibilities of the gas engine above all in lean operation and in the partial load range. A rotational speed-load-lambda-performance graph (36) is provided for producing lambda-desired values. The lambda-desired values readied by the rotational speed-load-lambda-performance graph (36) are compared with the lambda-actual values under formation of a lambda difference value.

Abstract: A dashpot for fuel tanks is designed such that gas bubbles produced in the latter can no longer cause troublesome noises within the fuel tank. This is achieved by means of a gas separation space which is separated from the dashpot intake chamber, into which a fuel return line opens and to the upper wall of which a degassing line discharging above the maxiumum fuel level in the fuel tank is connected.

The guide rail is provided with a flange abutting the descending inner sill wall and exhibiting terminally a cranked part behind which a part connected to the motor car seat engages.

Abstract: The invention relates to a laminar masking device, particularly for use in/on vehicles, comprising a plurality of surface sections mutually flexible with common bending axes, which are transferable alternately into two required bending positions and are retained therein. In order that the masking device may be particularly well adapted in the structural context to existing space conditions, it is flexible only at an obtuse angle at each bending axis located between two adjacent surface sections. A plurality of mutually aligned surface sections of the masking device are constructed as narrow connecting strips, and all the surface sections of the masking device are retained in the required mutual bending position by self-locking at the bending axes.

Abstract: A drive system for motor vehicles having driven front and rear axles comprises a liquid friction coupling, which is incorporated in the rear axle drive train, and a clutch, particularly an overrunning clutch, which is connected in series with said liquid friction coupling and arranged to be released in response to a front axle speed exceeding the rear axle speed. In order to avoid a requirement for stronger steering forces during a reverse travel and to avoid an operation of the liquid friction coupling with mixed friction, that second clutch is arranged to be automatically engaged in dependence on the liquid temperature in the liquid friction coupling or of other variables.

Abstract: A louver vent is disclosed which has successive levels, in flow direction, of in each case one set of slats which are pivoted by means of a joint operating handle. In order to provide air deflection corresponding to the associated slat position, at least one single slat is positioned ahead of the row of slats first subjected to flow, which single slat is arranged close to a housing wall of the slat of one of the rows of slats which is in the same alignment close to the wall. The single slat is moved, during the shifting of the operating handle, into a selected end position against the pivoting direction of the actuated slats after passing over their central position, so that the air stream is directed away from the housing wall and in the direction of the associated, oppositely disposed slats.

Abstract: A restraint device for the occupants of motor vehicles is described in which part of the wall of an airbag is designed as a filter. The filter has the keeps the particles released on ignition of the driving gas generator away from the internal space of the motor vehicle. The filter has a very high tear resistance so that the pores of the filter do not increase under load which would case the filter effect to decrease. A filter weave of aramid fibers in 2/1 twill weave with 24 threads per cm in the warp and 21 threads in the weft, the threads having a strength of dtex 250.times.2 Nm 40/2 is particularly advantageous.

Abstract: A piston-cylinder unit, which erects a swingable roll bar in a crash situation by an ejection spring, includes a controllable drive by which the movement and the direction of movement of the piston can be controlled and which can be disengaged in the event of a crash pulse, whereupon the piston extends rapidly by virtue of the ejection spring.

Abstract: The proper functioning of a control system (such as an ABS, ASR) that secures the adhesion of the wheels, by analyzing wheel rotating speed signals, is determined by comparing acceleration signals determined from the wheel rotating speed signals with accelerated signals measured by acceleration sensors on the vehicle. If they do not correspond within given limits during absence of control system control signal, the control system is disabled by an error signal and a warning indicator is activated.

Abstract: The invention concerns an external mirror for vehicles, having a mirror casing, in which a mirror glass is held so as to be adjustable, the mirror casing being held stationary, in the operating position, on a mirror base. In the event of a collision, the mirror casing can pivot away, either to the front or to the rear, about two approximately vertical axes located one behind the other in the direction of travel. In the case of a rigid streamlined fairing for both the mirror casing and the mirror base, there are certain problems in pivoting the fairing parts forward so as to avoid contact. To deal with this, the invention proposes a guide part which is rigidly located relative to the mirror casing and which interacts with a guide track in the mirror base. The guide track is so designed that when the mirror casing executes a pivoting motion in the forward direction, the mirror casing first lifts off from the mirror base.

Abstract: A repair method for repairing stone or gravel impact damages on windshields of multi-layer safety glass, in which the damaged place is covered with a transparent suction cup, a vacuum is produced underneath the suction cup and a liquid-clear hardening synthetic resinous material is applied onto the damaged place by means of an injection needle pierced through the suction cup. Compared to known repair methods, the method of this invention requires a lesser apparatus expenditure and can be carried out in a more simple manner.

Abstract: A arrangement for determining the injection course in an internal combustion engine in which the injection development could not be used heretofore in practice as guide magnitude in the engine control because no stationary measuring sensors are available for the pressure in the injection valve and a through-flow measurement at the feed line to the injection valve is very inaccurate by reason of the occurrence of gas, respectively, vapor bubbles. According to the present invention, the pressure in the injection valve, respectively, the quantity or the flow of the occurring injection medium is derived by a computer from signals of measurement transmitters which determine the stroke of the closure element of the injection valve and the pressure in the feed line to the injection valve or the force with which the closure element of the injection valve abuts in its open end position at an abutment.

Abstract: The aperture between a positionally stable vehicle passenger space end wall and a steering spindle shaft penetrating a bore in the wall is masked by a sealing sleeve which exhibits a bellows which compensates an offset of the shaft by modification of its form. Attached to the sealing sleeve is a second sleeve with which the first sleeve forms a sound-insulating closed air chamber.
