Definitions

  • a reversal of state of assembly C has the effect of triggering assembly D through the input E thereby saturating the transistor T which is connected to the output S of assembly D and the capacitor C discharges at a predetermined rate through the resistor P and said transistor T The discharge isstopped at the beginning of the following injection by a reversal of state of assembly D which is initiated in the case of the injection-commencement signal which is transmitted from the output S of assembly A to the input E of assembly D.
  • c. means for generating a reference voltage having a value dependent upon the spacing of said reference pulses in comparison to the duration of said control pulse
