Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
206 words
An apparatus comprising an intelligence capsule, a radio buoy, releasable means for retaining said buoy and said capsule attached together to be able to sink in sea water as a unit, pressure-responsive means for initiating release of said releasable means at a predetermined hydrostatic pressure, means for urging apart said buoy and capsule when said releasable means has been released; said capsule including a free-flooded chamber; a frangible cap; said chamber being formed at least in part by said frangible cap; in said chamber, a subsurface float assembly comprising an inflatable float adapted to break and remove said cap upon inflation, a winch containing a line connected to said buoy, and a depth compensating dispenser for line connecting said capsule with said subsurface float assembly, said dispenser including means to restrain payment of line from said dispenser; hydrostatic pressure responsive means, disabled from operation by said frangible cap, for activating said payment-restraining means, whereby said payment-restraining means is activated only upon removal of said frangible cap; means responsive to a coded sonic signal for causing said winch to release said buoy to rise to the surface of water; and means for causing said winch to retract said buoy to a predetermined depth below the water surface.
Claim 2
Independent Claim
206 words
An apparatus comprising an intelligence capsule, a radio buoy, releasable means for retaining said buoy and said capsule attached together to be able to sink in sea water as a unit, pressure-responsive means for initiating release of said releasable means at a predetermined hydrostatic pressure, means for urging apart said buoy and capsule when said releasable means has been released; said capsule including a free-flooded chamber; a frangible cap; said chamber being formed at least in part by said frangible cap; in said chamber, a subsurface float assembly comprising an inflatable float adapted to break and remove said cap upon inflation, a winch containing a line connected to said buoy, and a depth compensating dispenser for line connecting said capsule with said subsurface float assembly, said dispenser including means to restrain payment of line from said dispenser; hydrostatic pressure responsive means, disabled from operation by said frangible cap, for activating said payment-restraining means, whereby said payment-restraining means is activated only upon removal of said frangible cap; means responsive to a coded sonic signal for causing said winch to release said buoy to rise to the surface of water; and means for causing said winch to retract said buoy to a predetermined depth below the water surface.
Claim 3
Dependent Claim
37 words
The apparatus of claim 1 wherein said last named means operates on a predetermined absolute time cycle to cause automatic retraction of said buoy at times independent of the rising of the buoy to the water surface.
Claim 4
Dependent Claim
21 words
The apparatus of claim 1 wherein the buoy comprises a free-flooding chamber containing for buoyancy a plurality of hollow glass spheres.
Claim 5
Dependent Claim
41 words
The apparatus of claim 1 wherein said capsule includes a line dispenser to facilitate, without risk of breaking the line, relative displacement of said capsule and another body which is connected thereto by line, part of which is in said dispenser.
Claim 6
Dependent Claim
31 words
The apparatus of claim 1 wherein said capsule includes projections to engage the bottom of a body of water in the manner of an anchor to assist in mooring said apparatus.
Claim 7
Dependent Claim
31 words
The apparatus of claim 5 further including means operable at a predetermined time to cause said winch to retract said buoy to a predetermined distance below the surface of said water.
