Abstract
Abstract A conical chamber having a serrated bottom edge is provided with a centrally and upwardly supported bottom plate in order to distribute gas bubbles throughout a liquid when a gas is introduced under pressure into the chamber. In one embodiment, a second plate contacting the inner wall of the conical chamber, or an annular ledge formed thereon, acts as a check valve in the event of a gas pressure failure. In another embodiment, a resilient sleeve fitted about a gas inlet pipe having only circumferential openings acts as the check valve.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A gas distribution nozzle comprising, in combination: a hollow body formed of a generally conical umbrella like member, said member being closed at its apex and open at the end opposite the apex of the conical form to provide a gas outlet adjacent said open end, a relatively stiff bottom plate normally biased against the peripheral edge of said member; conduit means within said hollow body for connection to a source of gas pressure; and a check valve member internal of the hollow body positioned intermediate said conduit means and said outlet.
Claim 2
Dependent Claim
92 words
A gas distribution nozzle comprising, in combination: a hollow body formed of a generally conical umbrella like member, said member being closed at its apex and open at the end opposite the apex of the conical form to provide a gas outlet adjacent said open end, a relatively stiff bottom plate normally biased against the peripheral edge of said member; conduit means within said hollow body for connection to a source of gas pressure; and a check valve member internal of the hollow body positioned intermediate said conduit means and said outlet.
Claim 3
Dependent Claim
22 words
The gas distribution nozzle of claim 1 including a plurality of serrated opening formed in the peripheral edge of the umbrella-like member.
Claim 4
Dependent Claim
35 words
The gas distribution nozzle of claim 2 wherein the internal angle formed within the conical wall of the hollow body is relatively wide and the bottom plate is within the periphery of the conical member.
Claim 5
Dependent Claim
63 words
The gas distribution nozzle of claim 2 including a relatively resilient plate supported within the conical member inwardly of and adjacent said bottom plate, an annular ledge formed on the inner wall of the conical member, and means biasing the resilient plate against the annular ledge and said bottom plate positioned to limit the movement of said resilient plate away from said ledge.
Claim 6
Dependent Claim
55 words
The gas distribution nozzle of claim 2 wherein said conduit means comprises a pipe protruding throu1h the bottom plate and having only circumferential openings and including a resilient sleeve fitted about the portion of the pipe having said openings so as to seal said openings whenever sufficient pressure does not exist to expand said sleeve.
Claim 7
Dependent Claim
145 words
A gas distribution system for providing oxidation and circulation within a fluid including: a tank; a source of gas pressure mounted proximate said tank; a manifold supported within said tank and flow-coupled to said source through a conduit extending therebetween; a plurality of diffusers mounted on said manifold and having conduit means therein respectively adapted to be supplied with a pressurized gas therefrom, each said diffuser comprising a hollow body formed of a generally conical umbrella-like member, said member being closed at its apex and open at the end opposite the apex of the conical member to provide a gas outlet adjacent said open end, a relatively stiff bottom plate normally biased against the peripheral edge of said members, and a check valve member internal of said hollow body positioned intermediate said conduit means and said outlet, said diffusers being mounted vertically above said manifold.
