Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
86 words
A marine seismic cable comprising: a cable core that is substantially cylindrical, a housing adapted for holding an acoustic energy transducer that is substantially curved and the sizes of said cable core and said housing are defined by the equation R.sub.1 R.sub.3.sup.2 +R.sub.1 R.sub.2.sup.2 -2R.sub.2.sup.3 =0 where, R 1 : radius of said cable core; R 2 : inside radius of said housing; and R 3 : outside radius of said housing, and a body of elastic material positioned between said cable core and said housing.
Claim 2
Dependent Claim
86 words
A marine seismic cable comprising: a cable core that is substantially cylindrical, a housing adapted for holding an acoustic energy transducer that is substantially curved and the sizes of said cable core and said housing are defined by the equation R.sub.1 R.sub.3.sup.2 +R.sub.1 R.sub.2.sup.2 -2R.sub.2.sup.3 =0 where, R 1 : radius of said cable core; R 2 : inside radius of said housing; and R 3 : outside radius of said housing, and a body of elastic material positioned between said cable core and said housing.
Claim 3
Dependent Claim
14 words
A marine seismic cable as recited in claim 1, wherein said housing is cylindrical.
Claim 4
Dependent Claim
31 words
A marine seismic cable as recited in claim 2, wherein said body of elastic material is sized such that it occupies the entire space between said housing and said cable core.
Claim 5
Dependent Claim
45 words
A marine seismic cable as recited in claim 3, wherein said cable further comprises a cylindrical flotation body positioned around said cable core and sized such that the outside radius of said flotation body is substantially the same as the outside radius of said housing.
