Claim 1
Independent Claim
199 words
A MONOSTABLE MULTIVIBRATOR CIRCUIT COMPRISING, A PAIR OF ELECTRON VALVES EACH HAVING AT LEAST ONE CONTROL AND ONE OUTPUT ELECTRODE, SAID VALVES BEING BIASED SUCH THAT ONE VALVE IS NORMALLY ON OR CONDUITING AND THE OTHER IS NORMALLY OFF OR NONCONDUCTING, FIRST ELECTRIC STORAGE MEANS FOR RECEIVING TRIGGERING PULSES, FIRST ASYMMETRIC CONDUCTING MEANS FOR CONNECTING THE FIRST ELECTRIC STORAGE MEANS TO THE CONTROL ELECTRODE OF THE SAID ONE VALVE TO EXTINGUISH CONDUCTION WHEN A TRIGGERING PULSE IS APPLIED TO THE FIRST ELECTRIC STORAGE MEANS, MEANS FOR CONNECTING THE OUTPUT ELECTRODE OF THE SAID ONE VALVE TO THE INPUT ELECTRODE OF THE SAID OTHER VALVE TO TURN THE SAID OTHER VALVE ON WHEN THE SAID ONE VALVE IS TURNED OFF, SECOND ELECTRIC STORAGE MEANS CONNECTED TO THE OUTPUT ELECTRODE OF THE SAID OTHER VALVE AND BY AN ASYMMETRIC CONDUCTOR, WHICH IS ARRANGED TO OPPOSE THE CONDUCTION FROM THE FIRST ELECTRIC STORAGE MEANS, TO THE CONTROL ELECTRODE OF THE SAID ONE VALVE AND TO A CONSTANT CURRENT SOURCE WHICH DISCHARGES SAID SECOND STORAGE MEANS AT A CONTROLLED RATE, AND MEANS FOR CHARGING SAID SECOND STORAGE MEANS TO A PREDETERMINED VALUE EACH TIME IT IS DISCHARGED BY THE SAID CONSTANT CURRENT SOURCE.
