Abstract: The present invention relates to a method for monitoring at least one electronic switching contact for a door system for a vehicle, wherein the switching contact has a first connection for a first electrical line and a second connection for a second electrical line. The method comprises a step of reading a first signal from a first monitoring point connected to the first connection in order to obtain a first monitoring signal, a step of reading a second signal from a second monitoring point connected to the second connection in order to obtain a second monitoring signal, and a step of combining the first monitoring signal and the second monitoring signal in order to determine at least one state of the at least one switching contact.

Abstract: Means for supplying a fuel/air mixture to an internal combustion engine comprises a housing, means for injecting fuel into the housing, means for transferring sufficient heat to the fuel so that substantially all the fuel is vaporized when it leaves the housing, means for admitting air into the housing to form a mixture with the vaporized fuel, outlet conduit means for conducting the mixture out of the housing for combustion in the engine and, preferably, rotor means positioned in the outlet conduit means for rotation by the gases passing through the outlet conduit means.

Abstract: A carburetor for supplying a fuel/air mixture to an internal combustion engine comprises fuel regulation means for controlling flow rate of the fuel in response to a motor vehicle throttle and continuously feeding the fuel to the intake manifold of the engine, air admitting means for admitting air with the ejected fuel into the intake manifold, and fuel/air admixing means including a plurality of blades rotating by suction force due to the operation of the engine. The fuel and air passing through the fuel regulation means and the air admitting means, respectively, are atomizingly admixed and are fed to the engine through the intake manifold.

Abstract: A device for supplying fuel to an internal combustion engine comprises a shell, a tube received in the shell and a rod received in the tube with a sliding fit. A plurality of orifices in the tube at intervals along at least a portion of the length of the tube is provided. The rod is insertable in the tube to an extent sufficient to block the orifices and retractable to an extent sufficient to leave the orifices unobstructed. The number of orifices left unobstructed increases in proportion to the extent to which the rod is retracted. The rod includes means for connection to a linkage from a motor vehicle throttle for effecting axial movement of the rod. An annular space is defined between the exterior wall of the portion of the length of the tube having orifices and the portion of the length of the interior wall of the shell facing the orifices. Also provided are means defining passages for admitting liquid fuel into the annular space.

Abstract: A carburetor for an internal combustion engine comprises a housing, porous matter contained in the housing, means for injecting fuel into the housing and onto the porous matter to effect completion of vaporization of the fuel, means for admitting air into the housing to form a mixture with the vaporized fuel and means for conducting the mixture out of the housing for combustion in the engine. Preferably, means are provided for transferring heat from the exhaust gases of the engine to the housing and the porous matter and to the fuel before the fuel is injected into the housing.
