Claim 1
Independent Claim
119 words
A SYSTEM FOR PRODUCING A VARIABLE-DENSITY REPRESENTATION OF A SEISMIC WAVE COMPRISING A DETECTOR, MEANS FOR MOVING A PHONOGRAPHICALLY-REPRODUCIBLE SEISMOGRAM PAST SAID DETECTOR FOR PRODUCING AN ELECTRICAL SIGNAL REPRESENTATIVE OF THE VARIATIONS IN THE MAGNITUDE OF THE SEISMIC WAVE, A VARIABLE-FREQUENCY OSCILLATOR RESPONSIVE TO SAID ELECTRICAL SIGNAL FOR CONVERTING THE AMPLITUDE VARIATIONS OF SAID ELECTRICAL SIGNAL TO A FREQUENCY-MODULATED SIGNAL, A DIFFERENTIATOR RESPONSIVE TO SAID FREQUENCY-MODULATED SIGNAL TO PRODUCE SHARP PULSES, A PULSE GENERATOR RESPONSIVE TO SAID SHARP PULSES FOR GENERATING RECTANGULAR PULSES WHOSE FREQUENCY CORRESPONDS WITH THE FREQUENCY OF SAID FREQUENCY-MODULATED SIGNAL, MEANS FOR ENERGIZING AN ELECTRO-SENSITIVE RECORDING MEDIUM WITH SAID RECTANGULAR PULSES, AND MEANS FOR MOVING THE MEDIUM AT THE SAME RATE AS SAID SEISMOGRAM IS MOVED.
