Title: Improvements relating to thermionic valve circuits for generating scanning and like potentials
IPC: H03K4/12
Filed: 1945-01-25
Abstract: 601,675. Pulse and saw-tooth generating circuits. COSSOR, Ltd., A. C., and WILLIAMS, B. C. FLEMING-. Jan. 25, 1945, No. 1988. [Class 40 (vi.)] In a circuit employing a capacitor between the anode and grid of a valve with an impedance as an anode load, a valve is arranged in series with the capacitor to provide a low impedance path during fly-back. Triggered generator, switches in position 1. In the absence of a triggering pulse, valve V1 is cut off at the suppressor grid, the cathode current flowing to the screen grid, to maintain it at a low potential. The anode potential of valve V1 is maintained constant due to diode D1 conducting, the anode current of valve V2 being held at a small value due to the biassing resistance R12. The grid potential of valve V1 is held near earth by diode D2. A negative pulse, applied to the cathode of diode D1, over a coupling capacitor C5 causes a small fall in the anode potential of valve VI, and hence the grid and cathode of valve V2. This fall, communicated to the grid of valve V1 over capacitor C1, causes a drop in the cathode current, the screen grid potential rising and due to the coupling capacitor C2 the suppressor grid potential is also raised, being held at cathode potential by diode D4 conducting. Capacitor C1 commences to discharge over resistance R12 through valve V1, the potential drop across resistance R12 biassing off valve V2. The potential of the cathode of valve V2 falls linearly as condenser C1 discharges to provide the scanning voltage. When the anode potential of valve V1 falls to a low value, the anode current decreases and screen current increases, the screen grid potential and hence the suppressor grid potential falling to cut off the anode current. The cessation of anode current removes the paralyzing bias from valve V2, the valve passing heavy anode current to charge capacitor C1 rapidly to the potential where diode D1 conducts, the anode current then falling to the initial value. A positive impulse may be applied to the anode of diode D3 to raise the screen potential and . thus commence the cycle. A positive-going square wave may be taken from the anode of valve V2 or screen grid of valve V1. Free-running generator, switch in position 2. The linear fall in the potential of the cathode of valve V2 is terminated by the fall in the anode current of valve V1, decreasing the cathode bias on valve V2, the resulting anode current developing a potential drop across resistance R11 which drives the suppressor grid beyond cut-off to stop the flow of anode current. Capacitor C1 charges over valves V2, D1 and on nearing completion the fall in anode current of'valve V2 results in a rise in the suppressor grid potential of valve V1, thus allowing capacitor C1 to discharge and the cycle to recommence. Specification 575,250 is referred to.
