Abstract

708,305. Pulse generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 28, 1952 [Oct. 4, 1951], No. 23158/51. Class 40 (6) A pulse generator comprises a pair of normally non-conductive valves which are reciprocally coupled by means of transformers between anodes and control grids so that when a triggering pulse is applied both valves conduct heavily to produce a steep-fronted output pulse across a resistor connected in series with one of the valves. The Figure shows a pulse generator circuit comprising reciprocally-coupled valves V2, V3 which are normally non-conductive. When a positivegoing triggering pulse is applied at IN via stage V1 to the anode of valve V3 the negative pulse thus produced causes a current flow in the primary winding of transformer T2 and a positive pulse at the grid of valve V2. Valve V2 is thus rendered conducting and due to the regenerative action of transformers T1, T2 both valves V2, V3 conduct heavily to produce a positive output pulse across resistor R2. After a period when the current flows have reached saturation capacitor C2 becomes charged negatively to cut-off valve V3 at its control grid thus terminating the pulse. When capacitor C2 has discharged through resistor R1 the circuit is re-set in preparation for the reception of a further triggering pulse. The positive pulse generated across resistor R2 is applied to render valve V4 conductive, the fall in its anode potential driving the cathode of valve V5 negative to cause this valve to conduct and generate a pulse by reflection in delay line TL which may be derived from the terminal OUT. The control-grid of valve V5 is clamped by its connection to resistor R5 in the cathode circuit of the constant current pentode V6.
