Abstract
Abstract The invention involves a cooling tower with tower column having a hollow, rotatably mounted turret thereon, from the substantial periphery of which a plurality of equally, angularly spaced apart hollow vanes are suspended. Exhaust steam entered into the column passes upwardly and outwardly in the turret to pass downwardly through the vanes into an annular, rotatably mounted receiver. The receiver discharges the cooled fluid into a fixed reservoir, preferably an annular tank. Air around the column rises and passes outwardly through the vanes in heat exchange relationship therewith. The vanes, at least in their upper portions, are so constructed and directed, that the passage of air therethrough tends to impart rotation to the assembly of turret, vanes, and receiver.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
190 words
A fluid cooling tower including an upstanding tower column, an annular receiver with a circular track disposed radially outwardly of said column, means to mount said receiver for movement along said track a disc-shaped, hollow turret rotatably, sealably disposed about the top of said column and a shaft connected centrally at its top to said turret and antifrictionally, rotatably supported within said column, a plurality of hollow vanes having openings connected to said turret at points substantially equally angularly spaced about said turret, said vanes being suspended from said turret and being directed to discharge into said receiver, said vanes being constructed in such a manner that air from outwardly of said column may be drawn inwardly of said vanes, to pass upwardly and outwardly through said vanes adjacent said turret as hot fluid entering said tower is passed upwardly and outwardly therefrom into said turret and downwardly through said vanes into said receiver, said vane shape and disposition being such that air-vane contact tends to urge said turret and vanes into rotation in the course of air flow, and conduit means being provided to conduct away the cooled fluid.
Claim 2
Dependent Claim
190 words
A fluid cooling tower including an upstanding tower column, an annular receiver with a circular track disposed radially outwardly of said column, means to mount said receiver for movement along said track a disc-shaped, hollow turret rotatably, sealably disposed about the top of said column and a shaft connected centrally at its top to said turret and antifrictionally, rotatably supported within said column, a plurality of hollow vanes having openings connected to said turret at points substantially equally angularly spaced about said turret, said vanes being suspended from said turret and being directed to discharge into said receiver, said vanes being constructed in such a manner that air from outwardly of said column may be drawn inwardly of said vanes, to pass upwardly and outwardly through said vanes adjacent said turret as hot fluid entering said tower is passed upwardly and outwardly therefrom into said turret and downwardly through said vanes into said receiver, said vane shape and disposition being such that air-vane contact tends to urge said turret and vanes into rotation in the course of air flow, and conduit means being provided to conduct away the cooled fluid.
Claim 3
Dependent Claim
26 words
A fluid cooling tower as claimed in claim 1 which includes an annular support for said track, with said receiver being rotably supported by said track.
Claim 4
Dependent Claim
28 words
A fluid cooling tower as claimed in claim 2 which additionally includes a tank to receive cooled fluid from said receiver, and from which said conduit means extends.
Claim 5
Dependent Claim
25 words
A fluid cooling tower as claimed in claim 1 in which said vanes are rotatably, sealably received within said track as provided by said receiver.
Claim 6
Dependent Claim
33 words
A fluid cooling tower as claimed in claim 1 in which said conduit means returns said cooled fluid with remaining heat content thereof to be used in the fluid supplied into the column.
Claim 7
Dependent Claim
58 words
A fluid cooling tower as claimed in claim 1 in which a transfer ring is provided for suspension from said turret above said receiver, and in which said vanes comprise upper vanes carrying fluid outwardly and downwardly for discharge into said transfer ring, and lower vanes through which fluid passes downwardly from said transfer ring into said receiver.
Claim 8
Dependent Claim
77 words
A fluid cooling tower as claimed in claim 6, in which the upper vanes are spaced apart about said transfer ring inner periphery to provide escape slits for upwardly rising air as heated in the space within said vanes therebelow, and in which the trailing faces of upper vanes are concavely arcuate in direction of travel, with leading faces of adjacent vanes being spaced farthest from said trailing faces at respective outermost points of said upper vanes.
Claim 9
Dependent Claim
63 words
A fluid cooling tower as claimed in claim 6, in which said lower vanes are spaced apart outermost to provide entrance slits for outside air, and in which the trailing faces of the lower vanes are concavely arcuate in direction of travel, with leading faces of adjacent vanes being spacest farthest from said trailing faces at respective innermost points of said lower vanes.
Claim 10
Dependent Claim
39 words
A fluid cooling tower as claimed in claim 1 in which vane construction is of modified light structural steel angle stock for a base and transverse side, and is of a light metal, as aluminum, for a hypotemuse side.
Claim 11
Dependent Claim
22 words
A fluid cooling tower as claimed in claim 9, in which said hypotemuse side comprises the leading side in direction of travel.
Claim 12
Dependent Claim
52 words
A fluid cooling tower as claimed in claim 6, in which the vane construction is of modified lIght structural steel angle stock for a base and transverse side, and is of a light metal, as aluminum, for a hypotenuse side, and in which the upper vane, inwardly disposed base face is insulated.
Claim 13
Dependent Claim
28 words
A fluid cooling tower as claimed in claim 1, in which vane construction comprises inner and outer light metal plates spaced apart by light metal corrugated sheet material.

Claim 15
Dependent Claim
30 words
A fluid cooling tower as claimed in claim 1, which additionally provides motor-generator means automatically set motor operative responsive to a predetermined temperature of vane fluid, to abet turret-vane rotation.
Claim 16
Dependent Claim
41 words
A fluid cooling tower as claimed in claim 2, in which said receiver is selectively, drivably engaged on its inner face by generator-motor mounted means to abet turret-vane rotation by air passage inwardly of, and outwardly and upwardly through said vanes.
Claim 17
Dependent Claim
35 words
