Bistable diode switching circuits

Claim 1

A BISTABLE SWITCHING CIRCUIT COMPRISING: A PAIR OF INPUT TERMINALS; A PAIR OF OPPOSITELY POLED UNILATERAL CONDUCTING DEVICES CONNECTED BETWEEN SAID TERMINALS; A VOLTAGE DIVIDER COMPRISING TWO RESISTANCE ELEMENTS; MEANS CONNECTING THE JUNCTION POINT BETWEEN SAID RESISTANCE ELEMENTS TO THE JUNCTION POINT BETWEEN SAID UNILATERAL CONDUCTING DEVICES; A SOURCE OF NEGATIVE DIRECT CURRENT VOLTAGE; MEANS CONNECTING THE OPPOSITE END OF A FIRST ONE OF SAID RESISTANCE ELEMENTS TO SAID SOURCE OF NEGATIVE DIRECT CURRENT VOLTAGE; A TWO-TERMINAL DEVICE HAVING A REGION OF NEGATIVE RESISTANCE IN ITS OPERATING CHARACTERISTIC; A SOURCE OF POSITIVE DIRECT CURRENT VOLTAGE; AN INDUCTOR CONNECTED AT ONE END TO SAID SOURCE OF POSITIVE DIRECT CURRENT VOLTAGE; A RESISTOR HAVING END TERMINALS AND AN INTERMEDIATE TAP; MEANS CONNECTING THE END TERMINALS OF SAID RESISTOR RESPECTIVELY TO SAID INDUCTOR AND A FIRST TERMINAL OF SAID TWO-TERMINAL DEVICE; CAPACITOR MEANS FOR COUPLING THE JUNCTION POINT BETWEEN SAID UNILATERAL CONDUCTING DEVICES TO SAID INTERMEDIATE TAP; MEANS CONNECTING SAID FIRST TERMINAL OF SAID TWO-TERMINAL DEVICE TO AN OUTPUT TERMINAL AND TO THE OPPOSITE END OF THE SECOND ONE OF SAID RESISTANCE ELEMENTS OF SAID VOLTAGE DIVIDER; MEANS CONNECTING THE SECOND TERMINAL OF SAID TWO-TERMINAL DEVICE TO A REFERENCE POTENTIAL AND MEANS FOR SIMULTANEOUSLY APPLYING SWITCHING PULSES OF OPPOSITE POLARITY TO SAID INPUT TERMINALS.
