Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
A METHOD OF PRODUCING A RECORD CORRELATED WITH DEPTH OF ACOUSTIC LOGGING SIGNALS OBTAINED PERIODICALLY FROM A LOGGING TOOL MOVING AT A PREDETERMINED SPEED THROUGH A WELL BORE TRAVERSING EARTH FORMATIONS COMPRISING THE STEPS OF, PRODUCING IMPERMANENT VISUAL DISPLAYS ON A DISPLAY DEVICE OF SELECTED ONES OF SAID ACOUSTIC SIGNALS AS THEY ARE OBTAINED FROM THE LOGGING TOOL, GENERATING A SERIES OF PULSE SIGNALS HAVING A PREDETERMINED SPACING, BETWEEN SUCCESSIVE DISPLAYED ACOUSTIC SIGNALS PRODUCING ALONG A LINE TRAVERSING SAID DISPLAY DEVICE A VISUAL DISPLAY CORRESPONDING TO SAID PULSE SIGNALS TO PROVIDE A SERIES OF VISIBLE TIME BASE INDICIA, AND PHOTOGRAPHING THE OUTPUT OF SAID DISPLAY DEVICE TO PROVIDE A CONTINUOUS RECORD OF SAID ACOUSTIC SIGNAL DISPLAYS WITH ASSOCIATED TIME BASE INDICIA.

Claim 3
Dependent Claim
142 words
APPARATUS FOR MAKING A CONTINUOUS, VISUALLY INTERPRETATABLE RECORD OF A SUCCESSION OF PERIODICALLY OCCURING SIGNAL WAVEFORMS HAVING A PREDETERMINED TIME BASE COMPRISING, A SOURCE OF PERIODICALLY OCCURING SIGNAL WAVEFORMS, A CATHODE RAY TUBE HAVING A VIEWING SURFACE, CIRCUIT MEANS COUPLED TO SAID CATHODE RAY TUBE AND RESPONSIVE TO SAID WAVEFORMS TO PRODUCE VISIBLE REPRESENTATIONS THEREOF AS THEY OCCUR ON SAID VIEWING SURFACE, PULSE GENERATOR MEANS FOR PROVIDING A PULSE TRAIN HAVING A PERIODICITY RELATED TO SAID PREDETERMINED TIME BASE, MEANS RESPONSIVE TO SAID PULSE TRAIN TO REPETITIVELY PRODUCE ON SAID VIEWING SURFACE A SERIES OF VISIBLE DOTS BETWEEN SUCCESSIVE WAVEFORM REPRESENTATIONS, SAID DOTS EXTENDING ALONG A LINE TRANSVERSING SAID VIEWING SURFACE IN A DIRECTION CORRESPONDING, AND MEANS FOR EXPOSING A CONTINUOUSLY MOVING, PHOTOSENSITIVE RECORDING MEDIUM TO SAID VIEWING SURFACE, SAID RECORDING MEDIUM MOVING IN A DIRECTION PERPENDICULAR TO SAID TIME BASE DIRECTION.
