Claim 1
Independent Claim
95 words
IN THE METHOD OF SEISMIC EXPLORATION WHEREIN ARTIFICIALLY GENERATED SEISMIC WAVES ARE TRANSMITTED THROUGH THE EARTH''S CRUST FROM A TRANSMITTING LOCATION AND ARE DETECTED AT AT LEAST ONE RECEIVING LOCATION SPACED APART FROM THE TRANSMITTING LOCATION TO PRODUCE ELECTRICAL SIGNALS CORRESPONDING THERETO, AND WHEREIN THE ELECTRICAL SIGNALS ARE RECORDED TO FORM A MULTITRACE SEISMOGRAM, THE IMPROVEMENT COMPRISING: DROPPING IN SUBSTANTIALLY FREE FALL A HEAVY METAL PLATE TO THE EARTH''S SURFACE; AND AFTER THE PLATE HAS STOPPED FREELY FALLING, REPETITIVELY IMPACTING THE PLATE WITH FORCES OF PREDETERMINED MAGNITUDE AT INTERVALS OF BETWEEN .25 AND 20 MILLISECONDS.
