Title: Improvements in or relating to thermionic valve circuits for re-setting a relay at apredetermined period of time after the initial operation thereof
IPC: H04M3/12
Filed: 1949-03-21
Abstract: 666,162. Valve relay circuits. DECCA RECORD CO., Ltd., and BRIDGES, D. E. March 21, 1950 [March 21, 1949], No. 7595/49. Class 40 (vi). Fig. 1 shows a timing circuit in which initially the control grid of valve 12 is drawing grid current relay 10 is operated and contacts 14, 15 are open. When a negative pulse is applied to capacitor 20 to start a timing period, valve 12 is cut-off, relay 10 releases and contacts 14, 15 close. Capacitor 18 is charged from the H.T. supply until after a pre-determined time interval valve 12 is rendered conducting, relay 10 operates and the period is completed, contacts 14, 15 open and capacitor 18 completes its charging through the low value resistor 19 and the grid-cathode circuit of valve 12. In a modification, shown in Fig. 2, the positive going pulse which would be produced from the trailing edge of the negative triggering pulse by the two differentiating circuits comprising networks 19, 20 and 17, 18 of Fig. 1, and which might cause false triggering is substantially eliminated by increasing the time constant of network 20, 21 except during the presence of the negative going leading edge of the triggering pulse. The anode of diode 22 is at a potential set by divider 21, 24 which is normally below its cathode potential. When a negative pulse is applied after a delay, relay 10 is released and diode 22 is rendered conducting, the rapid recharge of capacitor 18 through the low value resistor 21 at the end of the timing cycle is accomplished. For positive going pulses the time constant of the input circuit 20, 23 is made very large.
