AN ELECTRICAL TRANSMISSION SYSTEM COMPRISING FIRST AND SECOND MEANS FOR PRODUCING ELECTRICAL PULSES OF OPPOSITE POLARITY, SUBSTANTIALLY ALL OF THE PULSES PRODUCED BY SAID FIRST MEANS OCCURRING AT DIFFERENT TIMES FROM THE PULSES PRODUCED BY SAID SECOND MEANS, EACH OF SAID FIRST AND SECOND MEANS HAVING FIRST AND SECOND OUTPUT TERMINALS; ONE OF SAID FIRST AND SECOND MEANS HAVING A D.C. INPUT TERMINAL; FIRST AND SECOND CAPACITORS; MEANS CONNECTING THE FIRST OUTPUT TERMINAL OF EACH OF SAID FIRST AND SECOND MEANS TO A FIRST SIDE OF SAID FIRST CAPACITOR; A FIRST ELECTRICAL CONDUCTOR CONNECTED BETWEEN A SECOND SIDE OF SAID FIRST CAPACITOR AND A FIRST SIDE OF SAID SECOND CAPACITOR; A SECOND ELECTRICAL CONDUCTOR HAVING A FIRST END THEREOF CONNECTED TO EACH OF THE SECOND OUTPUT TERMINALS OF SAID FIRST AND SECOND MEANS; A SOURCE OF DIRECT CURRENT CONNECTED BETWEEN SAID FIRST SIDE OF SAID SECOND CAPACITOR AND THE SECOND END OF SAID SECOND ELECTRICAL CONDUCTOR; MEANS CONNECTED BETWEEN SAID SECOND SIDE OF SAID FIRST CAPACITOR AND SAID FIRST END OF SAID SECOND ELECTRICAL CONDUCTOR FOR APPLYING THE DIRECT CURRENT VOLTAGE BETWEEN SAID SECOND SIDE OF SAID FIRST CAPACITOR AND SAID FIRST END OF SAID SECOND ELECTRICAL CONDUCTOR TO SAID D.C. INPUT TERMINAL; AND MEANS CONNECTED BETWEEN THE SECOND SIDE OF SAID SECOND CAPACITOR AND SAID SECOND END OF SAID SECOND ELECTRICAL CONDUCTOR FOR RECEIVING THE PULSES APPEARING THEREBETWEEN.
