Abstract
Abstract A nozzle for an exhaust duct is built up out of a plurality of wafers. Each wafer has on each side thereof a contour of one side of a two-dimensional nozzle along with one side of an inlet passageway thereto. When the wafers are stacked, adjacent wafers form an inlet passageway along with the converging and diverging portions of a nozzle; it can be seen that the nozzle is a twodimensional one having a relatively long lateral dimension as compared to the size of the throat. Spacing means for precise spacing appear along the length of each wafer and at the end thereof. Means for positioning and holding the wafers so that a precise nozzle configuration can be obtained and maintained is also included.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
In combination, a duct having a longitudinal axis for directing the passage of fluids therethrough, said duct having a first groove on one side of said duct and a second groove on the opposite side of said duct, said first and second grooves extending at an angle to said axis, wafers placed across said duct with opposite ends retained in said respective grooves, said wafers being slidably received in said grooves and stacked one on the other to extend across said duct, said wafers having spacing means to provide flow therebetween, sides of adjacent wafers being contoured so as to form a two-dimensional nozzle when assembled, means for holding said wafers in contact when fluid is flowing through said duct.
Claim 2
Dependent Claim
120 words
In combination, a duct having a longitudinal axis for directing the passage of fluids therethrough, said duct having a first groove on one side of said duct and a second groove on the opposite side of said duct, said first and second grooves extending at an angle to said axis, wafers placed across said duct with opposite ends retained in said respective grooves, said wafers being slidably received in said grooves and stacked one on the other to extend across said duct, said wafers having spacing means to provide flow therebetween, sides of adjacent wafers being contoured so as to form a two-dimensional nozzle when assembled, means for holding said wafers in contact when fluid is flowing through said duct.
Claim 3
Dependent Claim
82 words
A nozzle comprising a plurality of plates stacked together in contact forming a plurality of two-dimensional nozzles, said plates being formed on each side as one side of a two-dimensional nozzle, each plate having a spacing means at each end, adjacent plates having their spacing means contacting each other to properly space the cooperating sides of a two-dimensional nozzle, and means for holding said stack of plates in place when said nozzle is in use including means for slidably receiving said plates.
Claim 4
Dependent Claim
82 words
A nozzle comprising a plurality of plates stacked together in contact forming a plurality of two-dimensional nozzles, said plates being formed on each side as one side of a two-dimensional nozzle, each plate having a spacing means at each end, adjacent plates having their spacing means contacting each other to properly space the cooperating sides of a two-dimensional nozzle, and means for holding said stack of plates in place when said nozzle is in use including means for slidably receiving said plates.
Claim 5
Dependent Claim
20 words
A nozzle as set forth in claim 2 wherein each plate has additional spacing means between said end spacing means.
Claim 6
Dependent Claim
49 words
A nozzle as set forth in claim 3 wherein said additional spacing means is elongated and extends perpendicular to the throat of the nozzle, said means for slidably receiving said plates including guide means for insuring that the cooperating elongated spacing means of adjacent plates will engage each other.
Claim 7
Dependent Claim
51 words
A nozzle as set forth in claim 2 wherein said means for holding said plates together includes two side members, each side member having a long groove for slidably receiving said plates therein, said grooves facing each other, each of said stacked plates having its ends thereof positioned in said grooves.
Claim 8
Dependent Claim
29 words
A combination as set forth in claim 5 wherein said plates with their spacing means have aligned openings therethrough, pin means extending through said openings to properly align them.
Claim 9
Dependent Claim
50 words
A combination as set forth in claim 1 wherein said wafers have holes extending through the ends which are retained in said grooves, a rod extends through said cooperating holes on each end of said wafers to properly position said wafers with respect to said duct and to each other.
