Abstract: A control arrangement for an automatic change-speed transmission which is series-connected with an output of a driving engine. A gearshift control slide valve, a manually operable range selection control slide valve, and a gear-holding control slide valve operating in dependence upon a modulating control pressure related to the torque of the driving engine are connected in such a manner that the gearshift control slide valve is held in a position for a higher gear if the driving engine is in an idling position and the range selection control slide valve is in a position for a forward gear range. A downshift control member, operable by a control linkage of a power control of the driving engine affects the modulating pressure to be made effective at the gear-holding control slide valve in such a manner that, upon operating the control linkage from an idling position, the gear-holding control slide valve and gearshift control slide valve are brought into their positions for the lowest gear.

Abstract: An independent rear wheel suspension for passenger motor vehicles, with a wheel carrier being held through upper and lower wishbones and guided by way of a track rod, offset with respect to an axis of rotation determined by points of articulation of the upper and lower wishbones on the wheel carrier. The track rod engages the wheel carrier and extends in a transverse direction of a vehicle. Respective wheel carriers are pivotable under an influence of a longitudinal force acting on the respective wheels about an instantaneous center of rotation, present in a side view of the wheel suspension, due to the fact that elastic resilience is provided in at least one of the connections to the vehicle body formed by the wishbones.

Abstract: A connection for an exhaust gas return pipe which includes a duct spirally disposed around an intake pipe of an internal combustion engine. Exhaust gases flow through the duct and enter, from the spiral duct, through overflow openings into the intake pipe so as to enable the exhaust gases to be intensively mixed with the intake air.

Abstract: A method and apparatus is disclosed which enables quantities of fuel, successively injected from different injection nozzles into a measuring chamber which is bounded by a measuring piston, to be measured, even individually, without emptying this chamber between two successive injections by actuating a drain valve.For this purpose, a unidirectional and stepwise displacement of the measuring piston--starting, in each case, from its final position following its last yielding movement--is detected by a precision position transmitter and is evaluated by an electronic recording instrument.Measurements can be made quickly with respect to all the pump elements making up an injection pump, individually and successively, using only one measuring arrangement.

Abstract: An electronically controlled actuator arrangement with a temperature-compensated piezoelectric transducer. The transducer includes at least one stack of piezoelectric oxide discs. The actuator arrangement includes a mechanical throw-transmitting lever system arranged in series with the transducer. The lever system includes one or more levers and is integrated into a plane-parallel plate. When the actuator arrangement is in a rest position, a force introduction point or points lies flush with one plane face of the plate and a force deployment point or points lies flush with an opposite plane face of the plate. By virtue of the actuator arrangement, the lever system is not, to any substantial extent, affected by the temperature. The actuator arrangement is especially suitable for rapid-action hydraulic valves.

Abstract: An automotive retarder in which an outer toroid of at least one inner hydrodynamic operating cycle is bounded by inner surfaces of shells of at least two impellers engaged in the operating cycle. One of the impellers is adapted to be positioned by a thrust torque with another impeller by a counter support torque.

An annular slide valve is arranged concentrically with respect to an axis of rotation of the retarder with a sealing surface being provided on the valve which is stationary with respect to the valve. The annular slide valve may be displaced relative to the outlet aperture into a braking position such that the outlet aperture is closed off by the sealing surface of the annular slide valve and into at least one idling position unblocking the outlet opening to a greater or lesser extent.

Abstract: A hydrogen storage material is described which comprises an alloy of the composition of 25 to 30.9% by weight of Ti, about 10 to about 42% by weight of V and about 27.1 to about 65.1% by weight of Mn.

Up to about 0.2 atom of Cr per the titanium atom, up to about 0.1 atom of Ni per titanium atom and up to about 0.05 atom of Cu per titanium atom can also be present, but not more than about 0.1 atom of Ni plus Cu, these atoms replacing the same number of vanadium atoms.

Abstract: A linkage for operating a control element of an internal combustion engine is constructed in a manner such that a change in the inclination of the position of the internal combustion engine has no effect, or merely an intentional, minor effect on the relative position of a linkage operated control element for the internal combustion engine. In accordance with a first embodiment, by appropriately dimensioning and positioning a regulating lever along the longitudinal shaft directly operating the control element, rotation of the longitudinal shaft, during inclination of the engine, is matched, or caused to differ by a predetermined amount, so as to maintain a desired relationship between the position of the control element relative to the engine.

The carrier furthermore is supported by a transversely extending track rod offset laterally, as seen in a side view of the wheel suspension.

Abstract: A device for controlling the throttle valve of an internal combustion engine accepts input signals representative of vehicle velocity, gearshift position and roadway temperature which by logic means generates a first signal which is employed to modify a second signal received from a desired value generator which is under the control the gas pedal, the signal so modified being employed to control the throttle valve or injection pump position for the internal combustion engine wherein at idling speeds a large change in the accelerator pedal position effects a small change in the throttle valve position which control changes to effect an increasingly degressive transfer characteristic wherein a small change in accelerator pedal position effects a large change in throttle valve position as the vehicle velocity increases to a high velocity.

Abstract: A device for measuring wear of linings of a clutch, especially a motor vehicle clutch, with the clutch including a clutch-actuating device which has a push rod displaceable as a function of a position of, for example, a clutch pedal. A push rod includes a larger diameter portion which can be measured in a vicinity of a measurement point by means of a gauge, whereby the push rod acts upon a throwout fork which is adapted to be displaced as lining wear increases from a basic position in a direction of the push rod and indicate a need for replacement as a result of a predetermined change in diameter indicated by the group. The increased diameter portion of the push rod is formed by a frustoconical sleeve displaceable on the push rod. The sleeve is displaceable by a stop provided on a portion of a housing of the clutch when the clutch is thrown out for the first time into a fixed position corresponding to a maximum lining thickness.
