摘要： A chopper motor-controller for regulating a lift truck traction motor incorporates means for detecting faults which may cause the truck to run out of control, such as the high speed bypass contacts which shunt the semiconductor power switch being welded closed, and for disabling the controller in response thereto and also has time delay means for preventing a directional contactor from closing in on a fault before the fault detecting means can operate to disable the controller. The disclosed controller may alternatively be connected to require the operator to relax the accelerator foot pedal when starting or changing direction or to permit change of direction while the foot pedal is depressed.

摘要： A pulse width modulation chopper controller for a D.C. traction motor has plug sensing means which monitors the voltage across the motor armature on a pulse-by-pulse basis and is responsive, only when the power switch is turned on, to the motor acting as a generator to limit the "on-time" of the power switch before current of high magnitude can flow in the motor.

摘要： A weed destroying system carried on a vehicle and having electrodes for contacting weeds and a high voltage generator and a step-up transformer for supplying high voltage to the electrodes is provided with a tamper-proof safety system having redundant safety interlocks to effectively ground the vehicle and redundant safety interlocks to prevent energization of the generator until the vehicle is traveling at a predetermined speed and which de-energizes the generator if any one safety interlock is bypassed or fails in an unsafe condition, thereby requiring plural simultaneous failures to create a condition that is hazardous to the operator or to a bystander. The safety system also provides immediately-visible warning of the electrical hazard created by the apparatus and provides visual and aural indications to the operator when a safety interlock has been bypassed or is jammed closed.

摘要： A power transistor switch is protected against thermal destruction that might be caused by accidental short circuiting of the load being switched by a protective circuit having a base-drive-removing transistor in shunt to the base-emitter junction of the power transistor; an RC circuit including a capacitor in series with a resistor connected across the power transistor with the capacitor coupled across the base-emitter junction of the base-drive-removing transistor; a forward-biased shunting transistor connected across the capacitor; a shunt-removing transistor connected across the base-emitter junction of the shunting transistor; and a turn-on transistor triggerable to the conductive state by a turn-on signal for applying base drive to the power transistor and for forward biasing the shunt removing transistor to thereby turn off the shunting transistor and permit the capacitor to charge. Excessive current flow through the power switch causing it to desaturate results in charging the capacitor and consequent turning on the base-drive-removing transistor to thereby remove base current from the power transistor and turn it off.
