Amplifying arrangement

Claim 1

CIRCUIT ARRANGEMENT FOR AMPLIFYING SMALL AMOUNTS OF ELECTRIC ENERGY, COMPRISING, IN COMBINATION, FIRST DETECTOR MEANS INCLUDING ELECTRO-MAGNETIC MEANS RESPONSIVE TO INPUT OF SAID SMALL AMOUNTS OF ENERGY APPLIED THERETO; AUXILIARY MEANS CAPABLE OF FURNISHING A PULSATING ELECTRIC POTENTIAL, SAID AUXILIARY MEANS COMPRISING A SOURCE OF ELECTRIC ENERGY, GLOW LAMP MEANS, OSCILLATOR MEANS ENERGIZED BY SAID SOURCE AND CAUSING SAID GLOW LAMP MEANS TO EMIT LIGHT PULSES AT A PREDETERMINED PULSE FREQUENCY, PHOTO-ELECTRIC CELL MEANS ARRANGED IN THE PATH OF SAID LIGHT PULSES, AND CIRCUIT MEANS CONNECTED WITH SAID CELL MEANS AND WITH SAID SOURCE FOR SETTING UP AN OUTPUT POTENTIAL PULSATING AT SAID PULSE FREQUENCY; CONTROL MEANS INCLUDING A LIGHT BARRIER MEANS MOVABLE BY SAID ELECTROMAGNETIC MEANS ACROSS SAID PATH OF SAID LIGHT PULSES IN PREDETERMINED PROPORTION TO SAID INPUT OF SMALL AMOUNTS OF ENERGY APPLIED TO SAID DETECTOR MEANS, SAID LIGHT BARRIER MEANS BEING SO CONSTRUCTED THAT PROGRESSIVE MOVEMENT THEREOF ACROSS SAID PATH GRADUALLY CHANGES THE INTENSITY OF SAID LIGHT PULSES IMPINGING ON SAID CELL MEANS AND ACCORDINGLY CHANGES SAID OUTPUT POTENTIAL SUBSTANTIALLY IN PROPORTION WITH THE RESPONSE OF SAID FIRST DETECTOR MEANS TO AN INPUT OF SAID SMALL AMOUNTS OF ENERGY APPLIED THERETO; NORMALLY BLOCKED BLOCKING OSCILLATOR MEANS CONTROLLED BY SAID PULSATING OUTPUT POTENTIAL AND CAPABLE OF RELEASING, UPON INPUT OF A PREDETERMINED VALUE OF SAID PULSATING ELECTRIC POTENTIAL, AN AMPLIFIED PULSATING ENERGY AT SAID PREDETERMINED PULSE FREQUENCY; AND SECOND DETECTOR MEANS IN CIRCUIT WITH SAID BLOCKING OSCILLATOR MEANS FOR CAUSING THE DELIVERY OF A PERCEPTIBLE SIGNAL INDICATING THE INPUT OF SAID SMALL AMOUNTS OF ENERGY.
