Abstract: The present invention relates to a system for controlling the supply of air to an internal combustion engine having a supercharging unit which includes an exhaust turbine and a compressor driven thereby, there being arranged in an exhaust line between the engine and the supercharging unit an afterburner to which is fed fresh air from the compressor of the supercharging unit and fuel supplied from a fuel pump. According to the present invention an electrically driven air pump is arranged to feed supplementary air to the afterburner, and also recirculation means are provided for returning a portion of the exhaust gases from the afterburner to the engine via the exhaust turbine. In this way the torque characteristic of the engine is improved, and also the content of contaminating solid products in the exhaust gases is reduced.

Abstract: This invention is related to a safety checking device for an electronic braking system used primarily in wheeled vehicles and which indicates a malfunction of the system before the braking system is applied. The safety device introduces a signal to an electronic unit in the braking system; if there is a failure thereof, a warning circuit is triggered to give a proper alarm to the vehicle operator. The safety device is also designed so that it does not operate during application of the braking system.

Abstract: Clock pulses are generated at a rate synchronized to scanning of a substance with a light beam. The light is energized in pulses having uniform duration in terms of clock pulses. Output of a photocell responding to incident light is integrated to produce a reference signal of linearly varying magnitude. Magnitude of output of a photocell receiving light passed through the substance is compared with the reference signal, and a difference signal is produced whenever the difference between compared signals has a predetermined sign. During a predetermined uniform portion of every light pulse, clock pulses are counted so long as the difference signal persists, giving a digitized measure of substance transparency/opacity.

Abstract: The present invention relates to an arrangement for a motor vehicle fuel system. The arrangement comprises a fuel tank, a filler tube connected to the fuel tank and being sealable by a tank cap and a vent line opening into said fuel tank, the vent line being divided into at least two parts, e.g. a lower and an upper vent line. The vent line is connected to a filter means, which is connected to the intake system of the motor. This filter is capable of accumulating and filtering fuel vapors coming from the fuel tank, so that these vapors will not pollute the atmosphere. Instead, the vapors are sucked into the motor and burned when the motor is operating. The arrangement is chiefly characterized in tat the lower vent line, which is connected to the fuel tank, and one end of the upper vent line open into the filler tube at a place adjacent to the tank cap. Further, the end of the lower vent line opening into the filler tube can be sealed by means of a valve operated by the tank cap, the valve being arranged to close when the tank cap is removed and to open when the tank cap is mounted, and further, the upper vent line between the filler tube and the filter reaches, in a previously known way, substantially up to the highest point of the vehicle and constitutes a liquid trap for a gas-liquid mixture destined for the filter means.

Abstract: An arrangement for controlling and monitoring electronic control systems for the brakes of wheeled vehicles (motor cars) includes speed sensors, one for each controlled wheel, the output of each sensor being applied to a detector for detecting relative changes in speed of the wheel. The detector controls a number of solenoid valves to regulate the brake pressures for the individual wheels such that locking and skidding of any wheel is prevented. A delay circuit samples or senses the signal occurring in the output of the detector, which output is supplied to a driving stage driving the associated solenoid valve. The output of the delay circuit activates a comparator when the output of the detector results in a reduction or release of the braking power of one or more of the wheels of the vehicle during a period exceeding a normal transient period of the regulating system. When the comparator is activated, it energizes a switch provided for the associated driving stage such that the polarity of the output of this stage changes and results in switching on again the solenoid valve to open a braking-fluid connection to the normal, ordinary braking system of the vehicle. When the comparator is energized, a buzzer or signal lamp is also energized.

Abstract: A device for varying the pitch of the propeller blades in an engine driven boat. A hydraulic motor having a work cylinder with a working piston imparts movements to the propeller blades and to an auxiliary cylinder through a mechanical transmission member. The auxiliary cylinder includes a follow-up slide which cooperates with the transmission member. The transmission member has inlet and outlet openings and a channel to conduct a pressure medium to and from the working cylinder. The follow-up slide has inlet and outlet openings which cooperate with the openings in the transmission member so that control of the position of the working piston is determined by the position of the follow-up slide.
