Abstract: A front wheel suspension for motor vehicles with the use of a triangularly shaped guide member whose two guide arms are elastically supported at the vehicle superstructure in such a way that of the two guide arms, the forwardly disposed guide arm is directly elastically connected at the vehicle superstructure while the rear guide arm is connected with the vehicle superstructure by way of a cross yoke that is common to the wheel suspensions of both vehicle sides; the forward and rear guide arm of each triangular guide member are thereby pivotally connected with each other and a relatively radially soft bearing support is used for the forward guide arm at the vehicle superstructure; while the rear guide arm is pivotally connected at the cross yoke in such a manner that the connection of the rear guide arm with the cross yoke is constructed relatively hard at least in the direction of the line of force determined by its points of pivotal connection.

Abstract: A control system for regulating or controlling the actuating force of shifting elements which in automatically shifted change-speed transmissions act on friction elements that selectively brake, hold fast and release a structural element of such a change-speed transmission as a function of operating parameters; one of the operating parameters which is thereby used in the system of this invention is the predetermined change of the engine rotational speed as a function of time (dn/dt).

Abstract: A brake force control system for vehicles, especially for motor vehicles in which one or several electrical signals dependent on the wheel acceleration are compared with predetermined threshold values and in which the resultant electrical signals are utilized for the control of actuating elements such as solenoid valves in the brake circuit, whereby the electrical acceleration signals are weighted in a manner known as such and this weighting is adapted to be influenced or even discontinued when exceeding the threshold value and/or in dependence on the polarity of the acceleration signal.

Abstract: A method for separating deuterium from hydrogen in which the gaseous mixture of deuterium and hydrogen is brought into contact with TiNi, Ti.sub.2 Ni or a mixture of these alloys and after a delay sufficient for the absorption of hydrogen in the metal alloy, the non-absorbed residual gas is separated from the metal alloy.

Abstract: A continuous brake for motor vehicles, especially for heavy commercial vehicles, in the form of a hydrodynamic coupling, which is filled from a storage device during actuation of the brake valve and which is automatically emptied into the storage device when the brake valve is disengaged, a solenoid-actuated threeway valve is thereby arranged in the line from the brake valve to the storage device which, when energized, closes the line from the brake valve and vents the line to the storage device while a switch is connected in the energizing circuit of the solenoid valve which closes during actuation of the clutch pedal when the clutch is disengaged.

Abstract: A longitudinal bearer arrangement in vehicles, especially in passenger motor vehicles, in which the longitudinal bearers rise in the vehicle longitudinal direction from the rear section of the vehicle to the front section.

Abstract: A protective installation, especially for the passengers of motor vehicles, which is equipped with an air bag automatically inflatable by means of a gas when exceeding a predetermined vehicle deceleration; an insert which, in relation to the main flow direction of the gas, is disposed at a distance to the bag bottom during the inflation and which extends transversely to the main flow direction of the gas is thereby coordinated to the air bag; the insert forms in its area disposed in the main gas flow a baffle surface for the inflowing gas; the air bag is thereby securely connected with the insert within the area of its bottom facing the passenger while the insert is also anchored at a relatively fixed vehicle part by elastic retaining means.

Abstract: A system for the digital-electronic control of the inlet-, exhaust and possibly injection valves as well as of the ignition of internal combustion engines, especially of motor vehicle internal combustion engines, in which the valves are electromagnetically actuated and the respective crankshaft position is adapted to be detected digitally; a fixed value memory or storage device is provided in which at least for one cylinder the opening and closing instants of the inlet, exhaust, and possibly of the injection valves and/or of the ignition instants are at least partly adapted to be stored and selected as digital values coordinated to the respective operating conditions and corresponding to a predetermined crankshaft position in the form of data sets; a storage register is provided for each stored value of a data set to which this stored value is adapted to be transferred; a pulse comparison unit is also provided for each value of a data set in which the value either stored in the storage register or fixedly pre

Abstract: A hydrodynamic torque converter, especially for motor vehicles, which is equipped with a pump wheel, a turbine wheel and a guide wheel and with adjustable cascade at least at one of these wheels, preferably at the guide wheel; each blade of such wheel is thereby rotatably supported and is automatically adjustable against a spring force by the torque exerted by the circulating flow of the hydraulic medium.

Abstract: A fastening arrangement of one sheet metal member at another sheet metal member, especially of a fender at a motor vehicle body, in which embossments are arranged at the edge of one of the sheet metal members which keep the two edges at a distance from one another while the fastening is undertaken within the area of these embossments, for example, by threaded connections or welding.
