Variable impedance controlled phase shifter using squaring transistor with switching level thereof also controlled by variable impedance

Claim 1

A PHASE SHIFTING NETWORK COMPRISING: INPUT CONNECTING TERMINALS, OUTPUT CONNECTING TERMINALS, A PHASE SHIFTING CIRCUIT, A SWITCHING CIRCUIT, A TRANSISTOR AMPLIFIER INCLUDED IN SAID SWITCHING CIRCUIT, AND A VARIABLE RESISTOR INCLUDED IN SAID PHASE SHIFTING CIRCUIT, SAID PHASE SHIFTING CIRCUIT BEING CONNECFED BETWEEN SAID INPUT CONNECTING TERMINALS AND SAID SWITCHING CIRCUIT, SAID SWITCHING CIRCUIT BEING CONNECTED BETWEEN SAID PHASE SHIFTING CIRCUIT AND SAID OUTPUT TERMINALS, SAID PHASE SHIFTING CIRCUIT BEING RESPONSIVE TO A SOURCE OF ALTERNATING ELECTRICAL ENERGY APPLIED TO SAID INPUT TERMINALS THROUGH SAID PHASE SHIFTING CIRCUIT INCLUDING SAID VARIABLE RESISTOR TO PROVIDE A VOLTAGE INPUT SIGNAL PHASE SHIFTED FROM THE ENERGY OF SAID SOURCE AND APPLIED TO SAID TANSISTOR AMPLIFIER, SAID TRANSISTOR AMPLIFIER BEING BIASED TO ESTABLISH A SQUARE WAVE OUTPUT SIGNAL FOR APPLICATIUON TO SAID OUTPUT TERMINALS, SAID VARIABLE RESISTOR BEING CONNECTED FROM WITHIN SAID PHASE SHIFTING CIRCUIT TO SAID TRANSISTOR AMPLIFIER WITHIN SAID SWITCHING CIRCUIT TO CONTROL THE PHASE OF SIAD INPUT VOLTAGE OVER A PREDETERMINED RANGE APPLIED TO SAID TRANSISTOR AMPLIFIER, AND ALSO TO CONTROL THE VOLTAGE LEVEL AT WHICH SAID TRANSISTOR AMPLIFIER CONDUCTS, THEREBY ESTABLISHING AN ADDITIONAL PHASE SHIFT OF SAID SQUARE WAVE OUTPUT SIGNAL WITH RESPECT TO SAID VOLTAGE APPLIED TO SAID TRANSISTOR AMPLIFIER.
