Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 71 words
A fluid turbine system comprising: a vertical axis rotor; a plurality of vanes driving said rotor; an arcuate shield movable on pair of concentrically external to said vanes; tracks; said shield controlled in response to wind direction; said shield comprising externally placed, horizontally bracketted, vertical louvers as means to guide fluid current along the surface of said shield, the outlets of said louvers being parallel to and outside of said shield.
Claim 2
Dependent Claim 71 words
A fluid turbine system comprising: a vertical axis rotor; a plurality of vanes driving said rotor; an arcuate shield movable on pair of concentrically external to said vanes; tracks; said shield controlled in response to wind direction; said shield comprising externally placed, horizontally bracketted, vertical louvers as means to guide fluid current along the surface of said shield, the outlets of said louvers being parallel to and outside of said shield.
Claim 3
Dependent Claim 80 words
A fluid turbine system comprising: a plurality of vanes driving said rotor; an arcuate shield movable on tracks concentrically external to said vanes; said shield controlled in response to wind direction; wind direction means comprising a plurality of chambers; facing different points of the compass with their respective orifices; each one of said chambers includes a wind responsive spindle that on being moved by a fluid flow, will activate an electric switch transmitting power to a motor for said shield.
Claim 4
Dependent Claim 80 words
A fluid turbine system comprising: a plurality of vanes driving said rotor; an arcuate shield movable on tracks concentrically external to said vanes; said shield controlled in response to wind direction; wind direction means comprising a plurality of chambers; facing different points of the compass with their respective orifices; each one of said chambers includes a wind responsive spindle that on being moved by a fluid flow, will activate an electric switch transmitting power to a motor for said shield.
Claim 5
Dependent Claim 188 words
The fluid turbine system of claim 1 wherein said arcuate shield comprises externally placed, horizontally bracketted, parallel to itself, louvers; said shield being affixed to a corresponding section in one of a pair of parallel positioned cirumgyratory bands; said bands being spaced apart, having a plurality of vertical bars holding them and the shield together; said bands having a spur gear affixed to one of their circumferences; said spur gear spanning over said shield adjacent to its horizontal edges; said shield fitting into a recess made into said bands accomodating its horizontal width and thickness; said bars being affixed to the inner horizontal leg or backside of said bands; said bands having casters affixed to their respective horizontal areas; said shield further having affixed about its horizontal middle a bar; said bar having one long, notched horizontal edge matching the vertical edges of said louvers; said shield further having a pair of parallel concentrically external to said vanes, fixedly positioned tracks; said bands with shield, vertical bars, and casters forming a movable held in between said tracks, rotating unit; said rotating unit controlled in response to wind direction.
Claim 6
Dependent Claim 95 words
The fluid turbine system of claim 3 wherein said arcuate shield together with said bands and spur gear is controlled in response to wind direction; wind direction means comprising a plurality of chambers; said chambers facing different points of the compass with their respective orifices; one each of said chambers including a wind responsive spindle suspended over an electric switch; said switch being energized when said spindle is impinged upon by the wind; said shield further having an electric motor affixed to one of said tracks; said motor having a pinion gear about its shaft.
Claim 7
Dependent Claim 99 words
The fluid turbine system of claim 4 wherein said spur gear together with said shield and bands is set in motion by the action of one of said energized switches on the motor; said motor supplying motive force to said arcuate shield and bands via a pinion gear about its shaft; said pinion gear meshing into the spur gear will also stop said shield's motion via a spindle and switch located in a chamber; said chamber affixed to said shield's embodiment; said spindle when impinged upon by the wind will energize the switch beneath it stopping said shield's motion.
Claim 8
Dependent Claim 172 words
The fluid turbine system of claim 1 wherein said vanes further having a pair of parallel upper and lower triangular in shape frame members affixed to the respective upper and lower horizontal edges of said vanes; said upper and lower frame members serving as fastening points for spaced away, and parallel to the front of said vanes, partitions; said frame members having a hub in their respective apex's ; said hub fitting over a nipple-like projection central to the plate-like end-closures of a sectionalized cylinder surrounding a shaft central to said rotor; said nipple-like projection being central to the end-closures of said cylinder; said cylinder further having full-length horizontal projections bent outward from its embodiment; said cylinder's projections serving as fastening points for said vanes; said frame members joining a third vertical frame member at their distal points; said distal points forming angles to which casters are movably affixed; said casters running in or along a pair of fixedly positioned parallel tracks; said tracks serving said vanes steadying them in their rotation.
Claim 9
Dependent Claim 77 words
The fluid turbine system of claim 6 wherein said cylinder is fastened singularly or plurally about a vertical immoveable shaft; said cylinder rotating clock or counter clockwise in line with its rotor's rotational direction; said cylinder further having a nipple-like projection central to its end-closures; said nipple further having a sprocket about itself; said sprocket linked via a roller chain to a maindrive; said maindrive linked to either the armature or the field windings of a generator.
Claim 10
Dependent Claim 44 words
The Fluid Turbine System of claim 1 wherein said rotor comprises a vertical shaft; said shaft having a sectionalized cylinder about said shaft; said cylinder having a plurality of vanes (panels) affixed to said cylinder; said panels rotating when impinged upon by prevailing winds.
Claim 11
Dependent Claim 59 words
The Fluid Turbine System of claim 1 wherein said rotor's shaft has bearings on both of its ends; said shaft with its bearing equipped ends positioned in a frame, linked via endless roller-chain and sprocket combinations on alternate levels to a plurality of like rotor shafts; said rotor shafts being linked via a main drive to an electric generator(s).
Claim 12
Dependent Claim 40 words
The Fluid Turbine System of claim 8 wherein said shaft has a plurality of rotors in a skip-tier fashion clock or counter-clockwise movably affixed about itself; said rotors being linked to respective main drives via sprocket and chain combination media.
