Title: Improvements relating to apparatus for generating electrical pulses
Inventor: MOSS HERBERT FORSHAW
IPC: H03K3/543
Filed: 1951-10-03
Abstract: 701,946. Pulse generating circuits. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 28, 1952 [Oct. 3, 1951], No. 23078/51. Class 40 (6) A pulse generating circuit comprises a reflecting transmission line which is connected to a load in the anode circuit of a valve which has its grid held at constant potential and a cathode which is normally biased to cut-off but which is periodically driven negative to cause the valve to conduct thus initiating the generation of a pulse. The Figure shows a pulse generating circuit in which valves V1 and V2 are normally non-conductive, the control grid of valve V2 being clamped by the voltage drop across resistor R3 in the cathode circuit of a constant-current pentode valve V3. When a positive pulse is applied to terminal TRIP valve V1 conducts, the cathode of valve V2 is taken negative so that valve V2 conducts. The drop in voltage at the anode of valve V2 causes a negative going pulse to be applied to the input of the delay line, TL, the pulse is reflected at the distant short-circuited end and is thus applied back to the anode with reversed polarity to terminate the pulse, thus producing a negative-going pulse at terminal OUT.

[Also in Division G1] A process for simultaneously rolling one or more strands of wire in a continuous mill train includes the step of regulating the tension of the strands between two or more stands according to the measured cross-section of the wires. Two strands 16a and 16b of wire pass through a finishing mill having stands 4-9 driven from a common motor 2 and stands 14 and 15 driven from a motor 11. A thickness measuring device M, which can be a synchronously rotating polygonal mirror associated with an infra-red cell, measures the thickness of the section and feeds a signal corresponding to the difference between this and the desired thickness to the motor 11. The speed of the stands 14 and 15 is thus controlled to reduce this difference in thickness. The device M can be situated ahead of the last stands of the finishing mill, as shown, or beyond the final stand to control the motor of this final stand. Alternatively the two strands can be split before the final stand, each strand passing through a separate stand controlled by a measuring device ahead of the stand.
