Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
97 words
A submersible housing for submarine cable repeaters and equalizers comprising: a tubular casing having an internal annular seat; a bulkhead in said casing adjacent to said seat; an annular non-resilient seal between said seat and said bulkhead; a fixed annular clamping ring in said housing in front of said bulkhead; and a plurality of circumferentially-spaced-apart screws in said ring pressing said bulkhead toward said seat to compress said seal, said ring being constructed and arranged to act as a strong spring in the axial direction of said tubular casing to compress said seal in a resilient manner.
Claim 2
Dependent Claim
97 words
A submersible housing for submarine cable repeaters and equalizers comprising: a tubular casing having an internal annular seat; a bulkhead in said casing adjacent to said seat; an annular non-resilient seal between said seat and said bulkhead; a fixed annular clamping ring in said housing in front of said bulkhead; and a plurality of circumferentially-spaced-apart screws in said ring pressing said bulkhead toward said seat to compress said seal, said ring being constructed and arranged to act as a strong spring in the axial direction of said tubular casing to compress said seal in a resilient manner.
Claim 3
Dependent Claim
23 words
A submersible housing as set forth in claim 1 wherein: the radial thickness of said ring is greater than the axial thickness thereof.
Claim 4
Dependent Claim
60 words
A submersible housing as set forth in claim 1 wherein: said tubular casing has a fixed annular shoulder formed on the interior thereof facing said seat; the outer region of said ring engages said shoulder; and said screws are disposed in the inner region of said ring whereby said ring will dish when said screws are threaded toward said bulkhead.
