Abstract
Abstract A fluid aeration-agitation system featuring a pumping system and a pressure manifold operatively mounted upon a float which is either stationary or mounted for rotation, the manifold being operatively connected to a plurality of pipes each leading to a hollow discharge directing subsurface convection current or to a discharge head being hemispherical in configuration.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
111 words
A treatment and distribution system for a body of fluid, comprising: a pump; a manifold assembly operatively connected to said pump including a fluid intake and provided with at least one opening; a buoyant float together with means mounting said pump and manifold thereto; at least one fluid outlet conduit operatively connected to said opening, the outlet of said conduit extending out of the body of fluid; and discharge head means hemispherical in configuration and operatively connected to said conduit in a manner such that fluid ejected from said conduit strikes the inner concave surface thereof and is returned in the opposite direction along a curtain into the body of fluid.
Claim 2
Dependent Claim
111 words
A treatment and distribution system for a body of fluid, comprising: a pump; a manifold assembly operatively connected to said pump including a fluid intake and provided with at least one opening; a buoyant float together with means mounting said pump and manifold thereto; at least one fluid outlet conduit operatively connected to said opening, the outlet of said conduit extending out of the body of fluid; and discharge head means hemispherical in configuration and operatively connected to said conduit in a manner such that fluid ejected from said conduit strikes the inner concave surface thereof and is returned in the opposite direction along a curtain into the body of fluid.
Claim 3
Dependent Claim
36 words
A fluid treatment and distribution system as in claim 1, including a plurality of openings in said manifold, a conduit connected to each of said openings and a discharge head connected to each of said conduits.
Claim 4
Dependent Claim
28 words
A fluid treatment and distribution system as in claim 1, including means mounting said pump, manifold, float, conduit and discharge head for rotation within the body of fluid.
Claim 5
Dependent Claim
31 words
A fluid treatment and distribution system as in claim 1, including means mounting said pump, manifold, float, conduit and discharge head in stationary position with respect to the body of fluid.
Claim 6
Dependent Claim
26 words
A fluid treatment and distribution system as in claim 1, including interchangeable means for varying the depth below said fluid intake at which fluid is withdrawn.
Claim 7
Dependent Claim
19 words
A fluid treatment and distribution system as in claim 5, said means varying the depth including a draught tube.
Claim 8
Dependent Claim
16 words
A fluid treatment and distribution system as in claim 1, said manifold being toroidal in configuration.
