摘要: The invention is concerned with the rapid release of frictional force which is acting to reduce relative movement between contacting surfaces, the normal actuating means being unaffected. One application is in an anti-lock braking system in vehicles, particularly motor-cycles. A sensor monitors wheel angular velocity, calculates deceleration and when this exceeds a predetermined value the sensor causes ultrasonic vibrations to be applied to brake pads effectively reducing friction without release of brake operating pressure to enable resumption of normal rotation. A short duration dc pulse of appreciable magnitude may be applied to the transducer at the onset of the normal input signal to produce a short duration surge to rapidly break the frictional force between the friction member and the moveable member to enhance speed of release. The transducer may also be applied directly to the end wall of a friction member hydraulic operating cylinder when ultrasonic vibrations will be transmitted through the operating fluid to the piston connected to the friction member. The end wall of the cylinder is of a suitable matching material to facilitate transmission of the ultrasonic energy, and the piston is formed so as to minimize attenuation.The invention can also be applied to friction clutches operating in either rotary or linear senses to cause release when overloading or overspeeding occurs or to give gradual engagement in accordance with a predetermined program.

摘要: A liquid fuel tank for a vehicle is provided with a fuel outlet duct in a circuit about the base of the tank and fuel outlet duct vents connected to the outlet duct and extending above the highest part of the tank. During normal operation of the tank, a non-return air vent allows the flow of fuel from the outlet duct. In the event of an accident, or some other occurrence which results in the tank being tilted, further fuel flow from the outlet duct is cut off by air drawn into the fuel outlet duct from the outlet duct vents. The angle through which the tank must be tilted to allow air from the outlet duct vents to be drawn into the outlet duct may be predetermined by the extent of the circuit about the base of the tank of the outlet duct. Such a non-spill fuel tank, which is self contained in operation, is suitable for use in on-road and off-road wheeled and tracked vehicles, hovercraft, and aircraft which are in danger of being blown over when on the ground.
