Pulsed solenoid control valve

Apparatus for securing a motor vehicle against theft or loss includes a normally closed, electrically actuated fuel valve arranged in the fuel line of the motor vehicle between the fuel tank and the fuel pump. The fuel valve is actuated by an electric circuit having a hidden switch accessible to the driver. The hidden switch may be a simple two-position toggle switch, a receiver and transmitter system, or a three-terminal switch having an off-hold position with a warning buzzer.

Motor vehicle theft-prevention apparatus

A steering method and system for large aircraft wherein during low speed taxi the main landing gear wheels are steered and the nose gear is free to castor. During high speed taxi such as during take off and landing, the main gear steering is locked out while the nose gear is steered.

An automatic brake locking system, for locking the brakes of a vehicle having a hydraulic brake system, is operated every time the ignition switch is turned off to apply pressure through an auxiliary brake actuating device to lock the brakes and hold them locked until the auxiliary brake actuating device is released. A safety switch is provided to operate in conjunction with the ignition switch; so that the safety switch and the ignition switch both must be operated to an "on" position to release the auxiliary brake actuating device to allow normal operation of the vehicle. Turning on the ignition switch without operation of the safety switch does not permit movement of the vehicle since the auxiliary brake actuating device continues to be operated. The system is a passive system, which it does not require any separate actions on the part of the vehicle operator to cause the auxiliary brake actuating device to be operated when the vehicle ignition switch is turned off.
