Abstract: A fuel supply control system for an internal combustion engine includes a trigger circuit which is switchable between first and second states. The application of fuel to the engine is permitted when the trigger circuit is in the first state and is prohibited when the trigger circuit is in the second state. An energizing voltage is produced in response to deceleration of the engine. The trigger circuit is responsive to the presence of the energizing voltage to normally switch to the first state in which a feedback signal is developed. A control signal is generated having an amplitude proportional to the speed of the engine so that the amplitude of the control signal is at a trigger level when the engine speed is at a reference magnitude. The trigger circuit is responsive to the absence of the feedback signal to switch to the second state when the amplitude of the control signal exceeds the trigger level. Further, the trigger circuit is responsive to the presence of the feedback signal to remain in the first state when the amplitude of the control signal exceeds the trigger level due to an increase in the speed of the engine produced by the application of fuel to the engine as the engine speed initially decreases below the reference magnitude during deceleration of the engine.

Abstract: A speed control circuit for split phase motors of the type having the series combination of a phase winding and an electrical impedance element connected in parallel with the running winding. One diagonal of a resistive bridge circuit having at least one variable resistor is connected across the phase winding of the motor and the base-emitter electrodes of a transistor are connected across the other diagonal of the bridge circuit. With the bridge circuit unbalanced with a change of resistance value of the variable resistor in a direction to produce emitter-base current flow through the transistor, this device conducts through the emitter-collector electrodes to complete an energizing circuit for the gate-cathode electrodes of a silicon-controlled rectifier. The resulting gate-cathode current flow triggers this device conductive through the anodecathode electrodes thereof to complete a low resistance circuit in shunt with the phase winding of the motor.
