Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
137 words
An air distribution system for use in an acoustic seismic exploration system with a high pressure air supply comprising: reservoir means for receiving high pressure compressed air from one source; a plurality of major conduit means connected to said reservoir means for removal of a portion of said high pressure compressed air; a plurality of minor conduit means each connected to said major conduit means through a first electrically operated valve for simultaneously distributing said portion of said high pressure compressed air; a plurality of second electrically operated valves, connected to each of said minor conduit means to control pressure of said compressed air therein; and vent means connected to each of said minor conduit means through said second electrically operated valve; a plurality of acoustic air guns, each connected to one of said minor conduit means.
