Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
141 words
Apparatus for aerating water within a basin comprising, in combination: a frame adapted to float in the water; at least a pair of balded rotors, having longitudinal axes, rotatably mounted in said frame about their longitudinal axes, said blades extending radially from the longitudinal axes and projecting partially into the water; adjustable speed power means connected to each of said rotors to rotate them and propel the frame about the basin; guide means attached to said frame to direct it over a predetermined path on the water surface; and wherein one of said rotors is of a smaller diameter, as measured by the circular path traced by the blade tips, than the other rotor; one of said rotors rotates in the opposite direction with respect to the other rotor, thereby creating resistance to the movement of said frame in the water.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
45 words
Apparatus as set forth iN claim 1, wherein: said guide means comprises a. a pier anchored within the basin, and b. adjustable cable means connecting said pier with said frame so as define the path traced by said frame as it travels through the water.
Claim 4
Dependent Claim
152 words
Apparatus for aerating water within a basin comprising, in combination: a frame adapted to float in the water; at least a pair of bladed rotors, having longitudinal axes, rotatably mounted in said frame about their longitudinal axes, said blades extending radially from the longitudinal axes and projecting partially into the water; adjustable speed power means connected to each of said rotors to rotate them and propel the frame about the basin; guide means attached to said frame to direct it over a predetermined path on the water surface; the longitudinal axes of said rotors are parallel and in a horizontal plane; and wherein said rotors are positioned one behind the other, in the direction of frame travel; an adjustable baffle means is mounted on the frame between the rotors, said baffle means extends into the water to reduce the speed of the frame and promote the projection of air beneath the surface.
