Claim 1
Independent Claim
140 words
AN ELECTRICAL CIRCUIT FOR RELEASING PULSES OF RELATIVELY HIGH ELECTRIC ENERGY IN A RELATIVELY NONCOMPRESSIBLE DIELECTRIC MEDIUM COMPRISING A HIGH ENERGY ELECTRIC CIRCUIT COMPRISING A FIRST CAPACITOR, MEANS FOR CHARGING SAID FIRST CAPACITOR TO A RELATIVELY HIGH VOLTAGE AND THEREBY STORING A RELATIVELY LARGE MAGNITUDE OF ELECTRIC ENERGY THEREIN, MEANS FOR DISCHARGING SAID FIRST CAPACITOR, AND MEANS FOR TRANSMITTING THE STORED ELECTRIC ENERGY IN PULSE FORM TO A SPARK GAP POSITIONED IN A RELATIVELY NONCOMPRESSIBLE DIELECTRIC MEDIUM, AND A LOW ENERGY ELECTRICAL CIRCUIT COMPRISING A SECOND CAPACITOR, MEANS FOR CHARGING SAID SECOND CAPACITOR TO A VOLTAGE OF INTERMEDIATE MAGNITUDE, MEANS FOR DISCHARGE SAID SECOND CAPACITOR AND THEREBY PRODUCING A TRIGGERING PULSE OF ELECTRIC ENERGY OF RELATIVELY SMALL MAGNITUDE, AND MEANS FOR TRANSMITTING THE TRIGGERING PULSE TO SAID FIRST CAPACITOR DISCHARGE MEANS AND THEREBY INITIATING THE DISCHARGE OF SAID FIRST CAPACITOR.
