Abstract

582,758. Pulse generating circuits. WILLIAMS, F. C. June 25, 1943, No. 10351. [Class 40 (v)] A frequency counter or divider in which provision is made for controlling the duration of wave forms developed by the electrodes of the valve in response to applied impulses, comprises a multi-grid valve, the potentials of the electrodes of which pass through a predetermined cycle of changes in response to an applied impulse and then revert to their initial or stable condition, the cathode circuit including a feed-back resistance and the anode of the valve being back-coupled to the grid nearest to the cathode through a condenser. The arrangement is such that the cathode potential follows substantially that of the control grid and the time interval between the application of the impulse and the reversion to the stable condition is determined by the value of the fixed voltage to which the control grid tends to rise for given values of the difference between the anode and the control grid voltages in the stable condition and by the time constant of a circuit which includes the condenser coupling anode and the control grid. The Figure shows a valve V2 with a cathode load resistance R5 and with the anode and the control grid backcoupled by a condenser C2. The suppressor grid potential in quiescent state blocks the valve by diverting current to the screen grid while the anode and control grid voltages are fixed by the diodes V1, V3. If the cathode of the diode V1 is triggered by a negative impulse the potential of the control grid and cathode fall so that the anode takes current and its potential falls in a linear manner due to the feed-back of the potential to the control grid. When the anode potential approaches that of the cathode, the potential will then rise, following the control grid to which the anode potential is fed back through the condenser. In this way the anode current is again cut off and the valve reverts to the stable condition with the diodes conducting. Alternatively, the input may be a positive triggering impulse applied to the suppressor grid, Fig. 3 (not shown) or a negative triggering impulse may be applied to the cathode of the diode connected to the control grid, Fig. 1, provisional (not shown). The delay may be adjusted by varying the time constant circuit C2, R7, or by varying the initial anode voltage by varying potentiometer P3 or by varying the voltage to which the control grid tends to rise in the quiescent state as by connecting the resistance R7 to a potentiometer connected across the high-tension supply. Output is taken from the screened grid or the cathode according as a positive or a negative wave-form is required. The diodes may be in a common envelope with the pentode.
