Abstract

Abstract A wind power converter comprising: a pair of rotatable turbines with elongated curved blades disposed within a rotatable housing on axially parallel shafts, the curvature of the blades of one turbine being opposite to the curvature of the blades of the second turbine so that wind passing between said turbines will rotate the turbines in opposite directions; the housing comprising shaft-supporting sections at the ends of the turbines, lateral sections connecting the end sections, a pair of wind deflectors disposed between the end sections and extending from adjacent edges of the lateral sections toward the midpoint between the turbines and terminating approximately the same distance from each other as the distance between the turbine shafts, and a pivotally mounted vertically disposed vane extending from a portion of the housing opposite to the wind deflectors; said rotatable housing being supported on a vertically disposed central shaft and on a plurality of beams radiating therefrom with the free end of each beam having at least one pair of flanged wheels engaging a peripheral annular track with one wheel of each pair in contact with the top of the track and the other wheel of each pair in contact with the bottom of the track; means for synchronizing the rotation of the turbines; and fluid pumping means operatively connected to the turbine shafts.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 270 words
A wind power converter comprising: a pair of rotatable turbines with elongated blades disposed within a rotatable housing on axially parallel shafts, the curvature of the blades of one turbine being opposite to the curvature of the blades of the second turbine so that wind passing between said turbines will rotate the turbines in opposite directions; said housing including shaft-supporting sections at the ends of said turbines, lateral sections connecting said end sections, a pair of wind deflectors disposed between said end sections and extending from adjacent edges of said lateral sections toward the midpoint between said turbines and terminating approximately the same distance from each other as the distance between said turbine shafts, and a pivotally mounted vertically disposed vane extending from a portion of said housing opposite to said wind deflectors; said rotatable housing being supported on a vertically disposed central shaft and on a plurality of beams radiating from said central shaft with the free end of each beam having at least one pair of flanged wheels engaging a peripheral annular track with one wheel of each pair in contact with the top of said track and the other wheel of each pair in contact with the bottom of said track; means for synchronizing the rotation of said turbines; fluid pumping means operatively connected to said turbines mounted on said rotatable housing adjacent the top of said central shaft; conduit means within said central shaft communicating with said pumping means and adapted to be connected to remote power-consuming devices for extracting power from said wind power converter; and thrust bearings disposed on portions of said central shaft.
Claim 2
Dependent Claim 270 words
A wind power converter comprising: a pair of rotatable turbines with elongated blades disposed within a rotatable housing on axially parallel shafts, the curvature of the blades of one turbine being opposite to the curvature of the blades of the second turbine so that wind passing between said turbines will rotate the turbines in opposite directions; said housing including shaft-supporting sections at the ends of said turbines, lateral sections connecting said end sections, a pair of wind deflectors disposed between said end sections and extending from adjacent edges of said lateral sections toward the midpoint between said turbines and terminating approximately the same distance from each other as the distance between said turbine shafts, and a pivotally mounted vertically disposed vane extending from a portion of said housing opposite to said wind deflectors; said rotatable housing being supported on a vertically disposed central shaft and on a plurality of beams radiating from said central shaft with the free end of each beam having at least one pair of flanged wheels engaging a peripheral annular track with one wheel of each pair in contact with the top of said track and the other wheel of each pair in contact with the bottom of said track; means for synchronizing the rotation of said turbines; fluid pumping means operatively connected to said turbines mounted on said rotatable housing adjacent the top of said central shaft; conduit means within said central shaft communicating with said pumping means and adapted to be connected to remote power-consuming devices for extracting power from said wind power converter; and thrust bearings disposed on portions of said central shaft.
