Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
The method of beam emplacement in sea bottom areas comprising the steps of: providing a beam to be positioned near the sea bottom; providing a spreader with propulsion means to aid in the emplacement of said beam; providing explosive anchors and line; mechanically coupling said beam, spreader and explosive anchors together thereby forming a beam-anchor-spreader assembly; lowering said assembly towards said sea bottom; lowering said explosive anchor; firing said explosive anchors; and detaching said explosive anchors and said beam from said spreader.
Claim 2
Independent Claim
82 words
The method of beam emplacement in sea bottom areas comprising the steps of: providing a beam to be positioned near the sea bottom; providing a spreader with propulsion means to aid in the emplacement of said beam; providing explosive anchors and line; mechanically coupling said beam, spreader and explosive anchors together thereby forming a beam-anchor-spreader assembly; lowering said assembly towards said sea bottom; lowering said explosive anchor; firing said explosive anchors; and detaching said explosive anchors and said beam from said spreader.
Claim 3
Dependent Claim
28 words
The method of beam emplacement as set forth in claim 1 wherein the assembly position is sensed and corrected after said assembly is lowered toward the sea bottom.
Claim 4
Dependent Claim
25 words
The method of beam emplacement as set forth in claim 2 wherein assembly position is again sensed and corrected after said explosive anchors are fired.
Claim 5
Dependent Claim
35 words
The method of beam emplacement as set forth in claim 1 wherein assembly tilt position is corrected after said explosive anchors are fired by adjusting the length of line between said beam and said anchors.
Claim 6
Independent Claim
97 words
A system for beam emplacement in sea bottom areas comprising: a mechanical beam including underwater acoustic centers; spreader means for aiding the lowering of said beam toward the ocean floor and including sensors to sensing beam position; anchor means for tying said beam to the ocean floor; mechanical coupling means between said beam, spreader means, and anchor means forming a beam-anchor-spreader assembly; and control means for decoupling said spreader means from said beam and anchor means and for implanting said anchor means in the sea bottom when said sensors indicate said beam in a predetermined, desired position.
Claim 7
Independent Claim
97 words
A system for beam emplacement in sea bottom areas comprising: a mechanical beam including underwater acoustic centers; spreader means for aiding the lowering of said beam toward the ocean floor and including sensors to sensing beam position; anchor means for tying said beam to the ocean floor; mechanical coupling means between said beam, spreader means, and anchor means forming a beam-anchor-spreader assembly; and control means for decoupling said spreader means from said beam and anchor means and for implanting said anchor means in the sea bottom when said sensors indicate said beam in a predetermined, desired position.
