Abstract
Abstract A buoyant pipe system designed for underwater use of pipe conduits with equalized inside and outside pipe conduit pressures when transporting liquid, the conduits being thin-walled with external water inlet means, and being capped by a floatation chamber, the pipe system having a series of spaced anchor assemblies including an anchor member and a cable connector for anchoring the pipe conduit in an underwater floating condition.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
A submerged pipe system for underwater transport of liquids in a water body having an underlying bed comprising: at least one pipe conduit having means for substantially equalizing inside and outside conduit pressures during underwater use; a floatation chamber attached to said pipe conduit, said combined pipe conduit and floatation chamber having a positive buoyancy during underwater use; anchor means attached to said pipe conduit for anchoring said combined pipe conduit and floatation chamber to the underwater bed wherein said pipe conduit and attached floatation chamber are located in an elevated location above the underwater bed.
Claim 2
Dependent Claim
96 words
A submerged pipe system for underwater transport of liquids in a water body having an underlying bed comprising: at least one pipe conduit having means for substantially equalizing inside and outside conduit pressures during underwater use; a floatation chamber attached to said pipe conduit, said combined pipe conduit and floatation chamber having a positive buoyancy during underwater use; anchor means attached to said pipe conduit for anchoring said combined pipe conduit and floatation chamber to the underwater bed wherein said pipe conduit and attached floatation chamber are located in an elevated location above the underwater bed.
Claim 3
Dependent Claim
36 words
The pipe system of claim 1 wherein said means for substantially equalizing inside and outside conduit pressure comprises a valve device with means for admitting water from the water body, in which the pipe is submerged.
Claim 4
Dependent Claim
41 words
The pipe system of claim 1 wherein said pipe conduit has a top portion and a bottom portion and said floatation chamber is attached to the top portion and said anchor means is connected to said bottom portion of said conduit.
Claim 5
Dependent Claim
14 words
The pipe system of claim 3 wherein said floatation chamber is filled with air.
Claim 6
Dependent Claim
30 words
The pipe system of claim 3 wherein said anchor means comprises a piling imbedded in the underwater bed, said piling including a connecting element connecting said piling to said conduit.
Claim 7
Dependent Claim
30 words
The pipe system of claim 3 wherein said anchor means comprises a weight member on said underwater bed, said piling including a connecting element connecting said piling to said conduit.
Claim 8
Dependent Claim
29 words
The pipe system of claim 3 wherein said valve device means comprises a ball, a ball cage, and a vent mounted to the top portion of said pipe conduit.
Claim 9
Dependent Claim
37 words
The pipe system of claim 1 comprising further at least one feeder line connected to said pipe conduit, said feeder line having means for delivering liquids from a location above the water body to said submerged conduit.
Claim 10
Dependent Claim
20 words
The pipe system of claim 1 wherein said floatation chamber comprises an air bladder connectable and removable from said conduit.
Claim 11
Dependent Claim
29 words
The pipe system of claim 1 wherein said pipe system comprises a liquid waste discharge having a termination means on said conduit for discharging wastes into said water body.
