Sonic vibration locator and indicator
First Claim
1. AN INSTRUMENT FOR INDICATING THE INTENSITY OF SONIC VIBRATION COMPRISING, FIRST AND SECONS AMPLIFIER STAGES, AN INPUT CIRCUIT HAVING AN INPUT AND AN OUTPUT, TRANSDUCER MEANS FOR SUPPLYING A SIGNAL REPRESENTATIVE OF A SONIC VIBRATION FREQUENCY TO THE INPUT OF SAID INPUT CIRCUIT, A FIRST VOLTAGE DIVIDER CONNECTED TO THE OUTPUT OF SAID INPUT CIRCUIT AND A SECOND VOLTAE DIVIDER CONNECTED TO THE OUTPUT OF SAID FIRST AMPLIFIER STAGE, A GROUND CIRCUIT, FIRST SWITCHING MEANS CONNECTED TO THE INPUT OF SAID FIRST AMPLIFIER STAGE MOVABLE BETWEEN SAID GROUND CIRCUIT AND THE OUTPUT OF SAID INPUT CIRCUIT, AND SECOND SWITCHING MEANS MOVABLE WITH SAID FIRST SWITCHING MEANS CONNECTED TO THE INPUT OF SAID SECOND AMPLIFIER STAGE MOVABLE BETWEEN SAID FIRST AND SECOND VOLTAGES DIVIDERS, SAID SECOND SWITCHING MEANS CONNECTING ONLY SAID SECOND AMPLIFIER STAGE WITH THE OUTPUT OF SAID INPUT CIRCUIT WHEN SAID FIRST SWITCHING MEANS IS CONNECTED TO SAID GROUND CIRCUIT, AND SAID FIRST AND SECOND AMPLFYING STAGES CONNECTED IN SERIES WITH THE OUTPUT OF SAID INPUT CIRCUIT BY SAID FIRST AND SECOND SWITCHING MEANS WHEN SAID SECOND SWITCHING MEANS IS CONNECTED TO THE SECOND VOLTAGE DIVIDER, A METER FOR RENDERING AN INDICATION OF THE SIGNAL REPRESENTATIVE OF THE SONIC VIBRATION, AND A BANDPASS FILTER FOR PASSING SIGNALS WITHIN A PREDETERMINED RANGE OF SONIC VIBRATION FREQUENCIES CONNECTING SAID METER TO THE OUTPUT OF SAID SECOND AMPLIFIER STAGE.
