Abstract
Abstract A marine seismic wave generator is provided for generating acoustic impulses into a body of water. The generator includes a housing having an expansible combustion chamber in communication with the surrounding water. A core is provided in the combustion chamber. The combustion chamber periodically receives a charge of combustible fluid. The detonation of the charge causes the chamber to expand and to transmit to the surrounding water relatively high-energy, low-frequency seismic impulses.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A seismic gas exploder for generating seismic energy comprising: a housing having an expansible combustion and a wall defining a radiating surface area; control means in said chamber for controlling the ratio of radiating surface area to combustion chamber volume whereby the volume of the combustion chamber is substantially less than the volume contained within the radiating surface area; support means within said wall and spaced apart from said control means to maintain said wall at a predetermined distance from said control means to form between said control means and said wall said combustion chamber; supply means coupled with said chamber to supply a combustible gaseous mixture to said chamber; ignition means to detonate said mixture within said chamber thereby producing gaseous products of combustion which cause said chamber to expand thereby causing said wall to radiate seismic energy; and exhaust means operatively coupled to said chamber and arranged to purge said products of combustion.
Claim 2
Dependent Claim
155 words
A seismic gas exploder for generating seismic energy comprising: a housing having an expansible combustion and a wall defining a radiating surface area; control means in said chamber for controlling the ratio of radiating surface area to combustion chamber volume whereby the volume of the combustion chamber is substantially less than the volume contained within the radiating surface area; support means within said wall and spaced apart from said control means to maintain said wall at a predetermined distance from said control means to form between said control means and said wall said combustion chamber; supply means coupled with said chamber to supply a combustible gaseous mixture to said chamber; ignition means to detonate said mixture within said chamber thereby producing gaseous products of combustion which cause said chamber to expand thereby causing said wall to radiate seismic energy; and exhaust means operatively coupled to said chamber and arranged to purge said products of combustion.
Claim 3
Dependent Claim
29 words
The gas exploder system of claim 1 wherein: said control means is an open-ended core having a relatively large cross-sectional area, and said wall is a cylindrical elastic sleeve.
Claim 4
Dependent Claim
34 words
The gas exploder system of claim 2 wherein said support means includes a plurality of relatively small-diameter tubes positioned parallel to and at substantially the same distance from the longitudinal axis of said sleeve.
Claim 5
Dependent Claim
45 words
The gas exploder system of claim 3 wherein, said tubes are open-ended, said exploder is adapted to be moved through a body of water, and said water flows through said tubes and through said core during movement of said exploder through the body of water.
Claim 6
Dependent Claim
17 words
The gas exploder of claim 1 wherein said control means control the frequency of said radiated energy.
