Timing circuit employing scr diode

Claim 1

A MULTIVIBRATOR TYPE CIRCUIT COMPRISING: DIRECT CURRENT VOLTAGE SOURCE MEANS; CAPACITIVE IMPEDANCE MEANS COMPRISING A CAPACITOR AND CONNECTED ACROSS SAID VOLTAGE SOURCE MEANS; THE SERIES COMBINATION OF AN ELECTRON DISCHARGE DEVICE AND A DUAL WINDING LATCHING RELAY CONNECTED ACROSS SAID VOLTAGE SOURCE MEANS; SAID ELECTRON DISCHARGE DEVICE COMPRISING ANODE ELECTRODE MEANS, CATHODE ELECTRODE MEANS, AND ELECTRON CONTROL ELECTRODE MEANS; SAID DUAL WINDING LATCHING COMPRISING: FIRST AND SECOND WINDING MEANS EACH HAVING A FIRST AND SECOND TERMINAL WITH THE FIRST TERMINAL THEREOF CONNECTED TO AN ELECTRODE OF SAID ELECTRON DISCHARGE DEVICE; AND A PLURALITY OF CONTACTS AND ARMATURES OPERABLE TO CONNECT THE SECOND TERMINAL OF ONE OF SAID WINDING MEANS TO SAID VOLTAGE SOURCE MEANS AND TO DISCONNECT THE SECOND TERMINAL OF THE OTHER WINDING MEANS FROM SAID VOLTAGE SOURCE MEANS WHEN SAID OTHER OF SAID WINDING MEANS IS ENERGIZED; MINIMUN THRESHOLD VOLTAGE BREAKDOWN MEANS CONSTRUCTED TO ENERGIZE SAID ELECTRON DISCHARGE DEVICE WHEN THE POTENTIAL ACROSS SAID CAPACITOR REACHES A PREDETERMINED VALUE; AND ASYMMETRICAL IMPEDANCE MEANS TO PROVIDE A DISCHARGE FOR SAID CAPACITOR THROUGH SAID ELECTRON DISCHARGE DEVICE WHEN SAID ELECTRON DISCHARGE DEVICE IS ENERGIZED.
