Abstract: A device is disclosed for maintaining the pressurized gas source at a desired temperature in an inflatable, vehicle passenger, safety cushion system. The gas source is heated by a heating source such as the engine cooling water, air heated by the exhaust, or electrical energy, for example. A control system enables heating when the temperature of the gas source is below the desired temperature and disables heating when the gas source temperature is above the desired temperature.

Abstract: An installation is provided for increasing the difference in brightness between a pair of lights forming part of a combination light unit, particularly a unit including blinker and position lights for use in motor vehicles, so as to render the lights more easily distinguishable.In a system where a first and a second light are adapted to be switched on and off separately and are arranged in a common housing or in direct proximity of one another, a control element is provided whereby the first light is automatically turned off when the second light is turned on and is again automatically turned on when the second light is turned off.

Abstract: A standstill heating system for vehicles, especially for motor vehicles with a liquid-cooled internal combustion engine and with a controllable heater circulation equipped with at least one heat-exchanger, through which flows air intended to be heated and to be fed to the passenger space in the warmed-up condition; a line in communication with the liquid jacket of the internal combustion engine is thereby provided which includes a circulating pump and a heater apparatus whereby this line terminates in the heater circulatory system upstream of the control member controlling the quantity of flow through the adjoining heat-exchanger; a closure valve is also arranged in the heater circulatory system upstream of the place where this line terminates which prevents a return flow of the heated-up cooling liquid during standstill heater operation in by-passing relationship to the heat-exchanger.

Abstract: A clutch disk for motor vehicle main clutches, in which a disk member carrying the friction linings is torsionally elastically connected with a hub member, and in which several separate springs or spring sets with separate damping characteristics are provided; the springs or spring sets are thereby retained in windows provided in one of the two parts which are torsionally elastically connected with each other while the start of operation of at least one of the damping devices is determined by a sheet metal control member; a separate prestressed control spring is thereby coordinated to the control member.

Abstract: A method and apparatus for undertaking control measurements of a measurement object such as a motor vehicle frame or unit installed thereon, in which a directional beam or beams are used which extend only parallel to one coordinate axis and in which only one light source is used which emits directional beams toward one or two sides; only one parallel guidance coordinated thereto is provided which is securely connected at least indirectly with the vehicle, extending preferably perpendicularly to the vehicle longitudinal axis underneath the vehicle floor; the position of the control points perpendicular to the direction of the parallel guidance will be determined by direct mechanical measurements of the distance between the corresponding plumbing rulers, on the one hand, and the parallel guidance or a fixed point at the beam source, on the other.

Abstract: An internal combustion engine with applied ignition which includes at least one main combustion space and one ignition chamber coordinated to a respective main combustion space and connected therewith by way of an overflow channel and provided with a spark plug and an injection valve, and a fuel supply system for the ignition chamber independent of the fuel supply for the main combustion spaces which operates in such a manner that a fuel quantity is injected into the associated ignition chamber during a low pressure phase of the corresponding main combustion space; an electromagnetically actuatable valve which is electrically controllable in accordance with the ignition sequence of the internal combustion engine is thereby coordinated to each injection line whereby the electric control of the actuating magnets of the electromagnetically actuated valves takes place by way of a switch actuated by a cam rotating at a speed proportional to the engine rotational speed; the switch, in turn, is adapted to be changed

Abstract: A pneumatically operated control system for the automatic alignment of motor vehicle headlights in which a measuring transmitter at each axle of the motor vehicle determines the change in distance of the axle to the vehicle body and, cooperating with a pressure modulator, causes the alignment of the headlights to a constant light distance by way of a differential control element and a control shifting device; the control shifting device thereby includes a control rod engaging at the pivotal headlight which in case of pressure failure is clamped fast either directly or indirectly by a servo-adjusting motor which is operatively connected with the pressure line.

Abstract: A lateral protection for motor vehicles in which at least one reinforcement extending essentially in the vehicle longitudinal direction is arranged on the inside of each door, whereby in case of an external force influence or action which occurs in the vehicle longitudinal direction the reinforcements, preferably constructed as hollow bearers, are supported in the vehicle longitudinal direction with one end each either directly or indirectly at a fixed structural part such as, for example, at an upright column or at a wheel casing or at a further reinforcement belonging to an adjacent door.

Abstract: An injection pump for an air-compressing injection internal combustion engine with at least one pump element that consists of a cylinder and of a piston; the piston is provided with an upwardly disposed control edge for the control of the beginning of the feed of the piston; the control edge thereby changes the beginning of the feed during the rotation of the piston in dependence on the load in such a manner that the beginning of the feed, starting at the idling rotational speed, starts later compared to the feed beginning at full load and is kept essentially constant up to a predetermined load range.

Abstract: A drive for a motor vehicle with an internal combustion engine which is fed from a fuel tank with a fossil fuel by way of a fuel line; the fuel tank is thereby also connected with a cracking carburetor from which a line leads to a hydride storage device which, in turn, is connected with the internal combustion engine; the internal combustion engine can be operated with pure hydrogen or with a hydrogen-fuel-gas mixture in high density traffic areas as well as with a large excess of air whereas it can be operated on open highways, after shifting, with a conventional fossil fuel and with an air ratio number of about 1.
