Abstract: A system for controlling pressure in a container, for example the carburetor of an internal combustion engine, from a periodic acoustic source, for example the intake or exhuast of the engine or a selected engine component where the alternating pressure varies only slightly according to engine speed where it is desired to modify the slope of a fuel richness curve over a wide operating range. The system is characterized in that it comprises a conduit connecting the container chamber to the acoustic source, the pressure losses being different according to the direction of flow in the conduit.

Abstract: A method of and an apparatus for feeding hydrogen fuel derived from a metal hydride to an internal combustion engine includes two tanks, one for containing fresh hydride and the other for spent hydride and a low capacity reactor through which the fresh hydride is pumped from the one tank to the other. Heat applied to the small quantity of hydride in the reactor generates hydrogen which is extracted and retained in a storage chamber for feeding to an engine, with the spent hydride being pumped away and fresh hydride being pumped into the reactor to maintain a continuous source of supply of hydrogen therein during operation of the system. Quick starts and stops are made possible and great flexibility of operation and control are obtained by circulation of the hydride through the small reactor for heating.

Abstract: The gearbox has synchronizers and at least one speed ratio set of gears which is non-synchronized. The synchronized set of gears are actuated by parallel longitudinally movable rods. A first rod which moves the movable means is connected to a second rod which relates to one of the synchronizers by automatically withdrawable connecting means so that the beginning of the displacement from its position of rest of the first rod causes a displacement of the second rod, said displacement, which precedes the engagement of the non-synchronized set of gears, being of such extent that it just puts the synchronizers into action without engaging the corresponding speed ratio. The second rod carries a slidable sleeve having withdrawable means for connection to the second rod and means for positively driving the second rod at the same time as the first rod.

Abstract: This invention relates to a pedestrian protection device for motor vehicles which comprises essentially a hinged member adapted to be raised to an operative position from a normally lower inoperative position on the motor vehicle.More particularly, this hinged member constitutes a kind of transverse beam or barrier having side flanges provided with two series of connecting means associated with a pair of trunnions permitting the rotation of said beam and secured to said side flanges. The second series of connecting means provides an operative connection between the beam and the thrust rod of a cylinder and piston unit having its cylinder pivoted to the vehicle body. The essential purpose of this device is to protect pedestrians against the dangers of running into a car.

Abstract: An apparatus and method for detecting faulty combustion in an internal combustion engine. The series combination of a voltage source and a resistor are connected across the electrodes of a spark plug and the magnitude and shape of the voltage waveform across the resistor is indicative of whether or not a spark has occurred and whether or not combustion has occurred. An electronic processing circuit is provided for actuating an alarm or affecting the operations of some part of the engine or automobile when it is determined either that a spark has not occurred at the proper time or that a predetermined minimum number of consecutive sparks has occurred without the occurrence of combustion.
