Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
165 words
Apparatus of the class described comprising, in combination: a channel; means for supplying fluid to said channel; a member configured for insertion in the end of said channel to close at least a major central portion thereof and thereby produce a pair of aligned spaced outlet nozzles each defined in breadth by a wall of said channel and contiguous portion of a surface of said member; means rotatably mounting said member in said end of said channel for rotation about an axis extending transversely in said channel so that a significant portion of said member may project beyond said end of said channel, said surface being so configured with respect to said axis that the breadths of said nozzles do not change simultaneously in the same sense and at the same rate as said member rotates; and means for causing rotation of said member about said axis to vary the breadths of said nozzles and therefore the momenta of the streams issuing from said nozzles.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
39 words
Apparatus according to claim 1 in which the end of said channel embodies a pair of spaced plane walls normal to said axis and said member comprises a plate of uniform thickness equal to the space between said planes.
Claim 4
Dependent Claim
19 words
Apparatus according to claim 1 in which said surface has a curvature which is everywhere of the same polarity.
Claim 5
Dependent Claim
13 words
Apparatus according to claim 1 in which said surface is a convex cylinder.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 4 in which said axis passes through a point of other than the centroid of any section of said member normal to said axis.
Claim 7
Dependent Claim
21 words
Apparatus according to claim 5 in which the cross section of said member normal to said axis is a conic section.
Claim 8
Dependent Claim
35 words
Apparatus according to claim 5 in which the cross section of said member normal to said axis is a circle and said axis passes through said circle at a point other than the center thereof.
Claim 9
Dependent Claim
58 words
Apparatus according to claim 1 in which said surface is continuous on the downstream side of said member, so that jets from said nozzle attach to and wrap around said surface to impinge and thereupon detach from said surface as a single jet, the direction of said single jet being determined by the rotated position of said member.
Claim 10
Dependent Claim
16 words
Apparatus according to claim 8 together with means responSive to the direction of said single jet.
Claim 11
Dependent Claim
19 words
Apparatus according to claim 8 together with means giving a fluidic signal determined by the direction of said jet.
Claim 12
Dependent Claim
37 words
Apparatus according to claim 10 in which the last named means is a fluid amplifier receiver so positioned that when said single jet has a predetermined direction the jet passes equally into the legs of said receiver.
Claim 13
Dependent Claim
14 words
Apparatus according to claim 1 together with means causing continuous rotation of said member.
Claim 14
Dependent Claim
24 words
Apparatus according to claim 1 together with means for causing operation of the last named means in accordance with change in a variable quantity.
Claim 15
Dependent Claim
26 words
Apparatus according to claim 13 together with means connecting the last named means to a member whose angular position varies with respect to a normal position.
