Pulse responsive photosensitive electrooptical circuit

Claim 1

AN ELECTROOPTICAL CIRCUIT COMPRISING, FIRST AND SECOND TERMINALS ADAPTED TO BE CONNECTED TO A VOLTAGE SOURCE, A FIRST RESISTANCE AND A FIRST GAS DISCHARGE LAMP COUPLED IN SERIES RELATION BETWEEN SAID TERMINALS SUCH THAT SAID FIRST RESISTANCE IS NEAREST SAID FIRST TERMINAL, A SECOND RESISTANCE AND A SECOND GAS DISCHARGE LAMP COUPLED IN A PATH IN PARALLEL RELATION TO SAID FIRST RESISTANCE AND LAMP AND COUPLED IN SERIES RELATION WITH EACH OTHER SUCH THAT SAID SECOND RESISTANCE IS BETWEEN SAID FIRST TERMINAL AND SAID SECOND LAMP, EACH LAMP BEING ADAPTED TO INDIVIDUALLY ASSUME AT DIFFERENT TIMES A FIRED CONDITION AND AN UNFIRED CONDITION, BUT ONLY ONE AT A TIME OF SAID LAMPS BEING ADAPTED TO ASSUME THE FIRED CONDITION, A FIRST PHOTOCONDUCTIVE CELL ELECTRICALLY COUPLED IN PARALLEL RELATION TO SAID SECOND LAMP AND OPTICALLY COUPLED TO SAID FIRST LAMP TO RECEIVE LIGHT THEREFROM, A SECOND PHOTOCONDUCTIVE CELL ELECTRICALLY COUPLED IN PARALLEL RELATION TO SAID FIRST LAMP AND OPTICALLY COUPLED TO SAID SECOND LAMP TO RECEIVE LIGHT THEREFROM, AND A CAPACITANCE AND A BY-PASS RESISTANCE THEREFOR CONJOINTLY INTERPOSED IN CIRCUIT BETWEEN SAID SECOND CELL AND SAID FIRST LAMP, SAID CAPACITANCE BEING RESPONSIVE TO A COMMUNICATED VOLTAGE PULSE TO TRANSPOSE AMONG SAID LAMPS A FIRED CONDITION BEFORE SAID PULSE OF ONE OF SAID LAMPS AND AN UNFIRED CONDITION BEFORE SAID PULSE OF THE OTHER OF SAID LAMPS.
