Transistor power supply circuit

Claim 1

A REGULATED POWER SUPPLY COMPRISING, SUPPLY MEANS GENERATING A DIRECT CURRENT AND HAVING TWO TERMINALS, A LOAD HAVING TWO TERMINALS ONE TERMINAL OF SAID LOAD BEING DIRECTLY CONNECTED TO ONE TERMINAL OF SAID SUPPLY MEANS, A SERIES CONTROL TRANSISTOR HAVING AN EMITTER-COLLECTOR PATH CONNECTED AT ONE END TO THE OTHER TERMINAL OF SAID SUPPLY MEANS, SAID SERIES CONTROL RESISTOR HAVING A BASE TERMINAL, A CURRENT-SENSING RESISTOR HAVING ONE TERMINAL CONNECTED TO THE OTHER END OF SAID EMITTER-COLLECTOR PATH AND HAVING A SECOND TERMINAL, A TRANSISTOR HAVING ITS BASE CONNECTED TO SENSE THE POTENTIAL OF SAID SECOND TERMINAL RELATIVE TO SAID ONE TERMINAL OF THE SUPPLY MEANS AND HAVING A COLLECTOR TERMINAL, EMITTER FOLLOWER TRANSISTOR MEANS CONNECTING SAID COLLECTOR TERMINAL TO SAID SERIES CONTROL TRANSISTOR BASE FOR INCREASING THE RESISTANCE OF SAID EMITTER-COLLECTOR PATH IN PROPORTION TO SAID POTENTIAL, A CURRENT-LIMITING TRANSISTOR HAVING ITS EMITTER AND BASE CONNECTED ACROSS SAID CURRENT-SENSING RESISTOR TO SENSE THE POTENTIAL DROP THEREACROSS AND THEREBY TO SENSE SAID EMITTER-COLLECTOR PATH CURRENT, SAID CURRENT-LIMITING TRANSISTOR HAVING ITS COLLECTOR CONNECTED TO SAID COLLECTOR TERMINAL WHEREBY CONNECTION IS MADE THROUGH SAID EMITTER FOLLOWER TRANSISTOR MEANS TO SAID SERIES CONTROL TRANSISTOR BASE FOR INCREASING THE RESISTANCE OF SAID EMITTER-COLLECTOR PATH IN PROPORTION TO SAID EMITTE-COLLECTOR PATH CURRENT ABOVE A SELECTED CURRENT VALUE, AN ELECTROMAGNETIC RELAY HAVING A COIL AND NORMALLY OPEN CONTACTS, SAID COIL BEING CONNECTED TO A CAPACITOR AND TO SAID ONE TERMINAL OF THE LOAD, THE OTHER END OF SAID CAPACITOR BEING CONNECTED THROUGH A UNILATERALLY CONDUCTIVE DIODE TO SAID SECOND TERMINAL, A HIGH RESISTANCE RESISTOR SHUNTING SAID DIODE, SAID CONTACTS BEING CONNECTED TO SAID SECOND TERMINAL AND TO A RECTIFYING DIODE, THE OTHER TERMINAL OF SAID COIL AND DIODE BEING CONNECTED TO THE JUNCTION OF SAID COIL AND SAID CAPACITOR, AND A CONNECTION FROM THE OTHER TERMINAL OF SAID LOAD TO THE JUNCTION BETWEEN SAID CONTACTS AND SAID RECTIFYING DIODE.
