Title: Improvements in or relating to electric pulse coincidence indicators using cathode ray tubes
Inventor: BECK ARNOLD HUGH WILLIAM
IPC: H03K19/06
Filed: 1951-03-19
Abstract: 687,997. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. March 19, 1951, No. 6505/51. Class 39(i) [Also in Group XL(c)] Fig. 1 shows a two stable state or coincidence circuit comprising a cathode-ray tube 1 having an anode 5, deflecting plates 6, 7, 8, 9 and two target electrodes 10, 11 which are separated by a screen 12. Formulae are derived for the design of the deflecting plate system such that a given deflecting voltage has the same effect whether applied to plate 8 or to the commoned plates 7, 9. If the deflecting plates are initially biased so that the electron beam is incident only on target 10 then positive pulses applied simultaneously to input terminals 23 and 24 cause the beam to be deflected downwards to strike target 11 so that positive and negative output pulses are produced at terminals 30 and 31 respectively. The consequent voltage drop across resistor 18 lowers the potential on plate 6 and the beam thus remains incident on target 11 when the input pulses have terminated. The beam may be reverted to its original position by the application of a positive re-setting pulse to terminal 28 or of a negative pulse to either or both of terminals 23, 24. The circuit may be used to detect the coincidence of any given number of input pulses by dividing the lower deflecting plate system into a suitable number of sections.
