Multistage amplifier coupled to an inductive load

Claim 1

A MULTISTAGE PULSE POWER AMPLIFIER COMPRISING FIRST AND SECOND LIKE CONDUCTIVITY TYPE TRANSISTORS EACH WITH EMITTER, COLLECTOR AND BASE ELECTRODES, MEANS FOR RECEIVING A PREDETERMINED REFERENCE VOLTAGE COUPLED TO EACH OF SAID EMITTER ELECTRODES, MEANS COUPLED TO SAID BASE OF THE FIRST TRANSISTOR FOR RECEIVING AN INPUT PULSE TO CAUSE SAID FIRST TRANSISTOR TO CONDUCT CURRENT IN THE ABSENCE OF SAID INPUT PULSE BUT NOT IN THE PRESENCE THEREOF, ND INTERSTAGE COUPLING MEANS FOR CAUSING SAID SECOND TRANSISTOR TO START CONDUCTING AS SOON AS SAID FIRST TRANSISTOR BECOMES NON-CONDUCTIVE OF SAID CURRENT AND TO REMAIN CONDUCTING WHILE SAID FIRST TRANSISTOR IS SO NONCONDUCTIVE, SAID INTERSTAGE COUPLING MEANS INCLUDING, AN INDUCTOR HAVING ONE TERMINAL THEREOF SERIALLY CONNECTED WITH THE FIRST TRANSISTOR COLLECTOR ELECTRODE AND THE OTHER END OF SAID INDUCTOR SERIALLY COUPLED THROUGH RESISTIVE MEANS TO SAID INPUT MEANS, SO THAT SAID COLLECTOR CURRENT PASSES THROUGH THE INDUCTOR WHILE THE FIRST TRANSISTOR IS CONDUCTING, MEANS COUPLED TO THE BASE AND EMITTER
