Stabilized oscillator power source with feedback diode capacitance controls

Claim 1

A STABILIZED POWER SOURCE COMPRISING, IN COMBINATION: AN OSCILLATOR PROVIDING OUTPUT POWER FOR A LOAD; A POTENTIOMETER HAVING A MOVABLE CONTACT ARM AND A RESISTANCE ELEMENT, THE LATTER BEING CONNECTED TO SAID OSCILLATOR SO THAT THE LOAD CURRENT FLOWS THERETHROUGH; AN A.C. AMPLIFIER DERIVING ITS INPUT FROM SAID MOVABLE CONTACT ARM OF SAID POTENTIOMETER; RECTIFIER-AND-FILTER MEANS CONNECTED TO SAID A.C. AMPLIFIER FOR OBTAINING A D.C. VOLTAGE PROPORTIONAL TO THE OUTPUT OF SAID D.C. AMPLIFIER; CONNECTIONS TO A SOURCE OF POWER PROVIDING A FIXED COMPARISON VOLTAGE; A D.C. AMPLIFIER-COMPARATOR, CONNECTED TO SAID COMPARISON VOLTAGE CONNECTIONS AND TO SAID RECTIFIER-AND-FILTER MEANS, FOR AMPLIFYING THE DIFFERENCE BETWEEN THE OUTPUT OF SAID RECTIFIER-AND-FILTER MEANS AND SAID FIXED COMPARISON VOLTAGE; AND VARIABLE-CAPACITANCE MEANS CONNECTED TO SAID D.C. AMPLIFIER AND SAID OSCILLATOR, SAID VARIABLE-CAPACITANCE MEANS COMPRISING A JUNCTION DIODE WHOSE CAPACITANCE IS VARIABLE IN ACCORDANCE WITH THE D.C. VOLTAGE APPLIED THERETO FROM SAID D.C. AMPLIFIER, CHANGES IN THE CAPACITANCE OF SAID DIODE DUE TO CHANGES IN APPLIED D.C. VOLTAGE RESULTING FROM CHANGES IN OUTPUT CURRENT OF SAID OSCILLATOR CAUSING THE STRENGTH OF OSCILLATION TO VARY SO AS TO COMPENSATE FOR SAID CHANGE IN OSCILLATOR OUTPUT CURRENT AND RETURN SAID OUTPUT CURRENT TO ITS ORIGINAL LEVEL.
