Abstract
Abstract A water current directing unit including an essentially open frame structure for supporting a plurality of flexible, vertically spaced current directing surfaces. Each of the current directing surfaces is inclined slightly upward from the horizontal toward the downstream end of the frame structure causing the water passing over the surfaces to force the unit toward the bottom of the stream, channel, etc. (i.e. to anchor the unit). The upstream edge of each of the current directing surfaces is pivotably attached to the frame structure and each of the corners along the downstream edges is independently moveable in the vertical direction so as to form a curved current diverting surface. A plurality of the current directing units can be positioned in either a series or parallel arrangement so as to effect the desired current diversion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
199 words
Apparatus for directing the flow of a fluid, comprising: a. means defining a generally open frame structure suitable for positioning in the fluid flow; b. means defining a current directing member mounted within said frame structure for allowing fluid flow thereover and including a generally planar, flexible continuous surface having a portion thereof moveable between a first position and a second position inclined to the plane of the remainder of said flexible continuous surface so as to redirect the fluid passing thereover; said flexible continuous surface having a pair of oppositely disposed, downstream corner positions; c. actuating means associated with said current directing member for moving said moveable portion between said first and second positions and for causing deformation of said flexible continuous surface, said actuating means including a pair of vertically extending threaded crank members, each mounted for rotation within said frame structure; d. means connected to said current directing member for threadedly receiving each of said crank members to provide vertical movement of one of said downstream corner portions upon rotation of one of said crank members and vertical movement of the other of said downstream corner portions upon rotation of the other of said crank members.
Claim 2
Dependent Claim
199 words
Apparatus for directing the flow of a fluid, comprising: a. means defining a generally open frame structure suitable for positioning in the fluid flow; b. means defining a current directing member mounted within said frame structure for allowing fluid flow thereover and including a generally planar, flexible continuous surface having a portion thereof moveable between a first position and a second position inclined to the plane of the remainder of said flexible continuous surface so as to redirect the fluid passing thereover; said flexible continuous surface having a pair of oppositely disposed, downstream corner positions; c. actuating means associated with said current directing member for moving said moveable portion between said first and second positions and for causing deformation of said flexible continuous surface, said actuating means including a pair of vertically extending threaded crank members, each mounted for rotation within said frame structure; d. means connected to said current directing member for threadedly receiving each of said crank members to provide vertical movement of one of said downstream corner portions upon rotation of one of said crank members and vertical movement of the other of said downstream corner portions upon rotation of the other of said crank members.
Claim 3
Dependent Claim
27 words
The fluid flow directing apparatus of claim 1 wherein said current directing surface is upwardly inclined from the horizontal toward the downstream end of said frame structure.
Claim 4
Dependent Claim
37 words
The fluid flow directing apparatus of claim 1 wherein said current directing means includes first and second generally similar current directing members extending essentially parallel to one another within said frame structure in a vertically spaced relationship.
Claim 5
Dependent Claim
33 words
The fluid flow directing apparatus of claim 3 wherein each of said current directing members are a generally flat, rectangular shaped member having the upstream ends thereof pivotably connected to said frame structure.
Claim 6
Dependent Claim
54 words
The fluid flow directing apparatus of claim 4 including an anchoring member fixedly mounted within said frame structure below said current directing surfaCe and having a generally planar surface inclined upwardly toward said downstream corner portions for causing the fluid passing thereover to exert a downward force thereon anchoring the apparatus within the flow.
Claim 7
Dependent Claim
177 words
Apparatus for directing the flow of a liquid comprising: a. a generally open frame structure suitable for positioning in the fluid flow; b. at least one deformable current directing member mounted within said frame structure, said current directing member being inclined slightly upward from the horizontal toward the downstream end of said frame structure and having a generally rectangular planar surface and the upstream corners of said surface pivotably attached to said frame structure; c. actuating means carried by said frame structure and connected to the downstream corner portions of said current directing member for independently moving either of said corner portions in an upward direction so as to cause temporary upward deformation of a said downstream corner portion of said generally rectangular planar surface; and d. an anchoring member fixedly mounted within said frame structure in a vertically spaced relationship below said current directing member and having a generally planar surface inclined upwardly toward said downstream corner portions for causing the fluid passing thereover to exert a downward force thereon anchoring the apparatus within the flow.
Claim 8
Dependent Claim
177 words
Apparatus for directing the flow of a liquid comprising: a. a generally open frame structure suitable for positioning in the fluid flow; b. at least one deformable current directing member mounted within said frame structure, said current directing member being inclined slightly upward from the horizontal toward the downstream end of said frame structure and having a generally rectangular planar surface and the upstream corners of said surface pivotably attached to said frame structure; c. actuating means carried by said frame structure and connected to the downstream corner portions of said current directing member for independently moving either of said corner portions in an upward direction so as to cause temporary upward deformation of a said downstream corner portion of said generally rectangular planar surface; and d. an anchoring member fixedly mounted within said frame structure in a vertically spaced relationship below said current directing member and having a generally planar surface inclined upwardly toward said downstream corner portions for causing the fluid passing thereover to exert a downward force thereon anchoring the apparatus within the flow.
Claim 9
Dependent Claim
37 words
Apparatus according to claim 6 wherein said apparatus includes a second current directing member mounted within said frame structure in a generally parallel, vertically spaced relationship above said anchoring means and below the other current directing member.
Claim 10
Dependent Claim
55 words
Apparatus according to claim 6 wherein said actuating means includes a pair of crank members each mounted for rotation within said frame structure and said current directing includes means for receiving each of said crank members to provide independent vertical movement of each of said corner portions upon rotation of either of said crank members.
