Abstract
Abstract A fluidic pulse and flow divider which has a single input and a plurality of outlet channels which communicate with the input and are disposed at an acute angle with respect to the fluid flow in the entrance section to provide a plurality of fan-outs exiting toward one side of the device. The combined area of the outlets is equal to the area of the entrance flow straightening section to eliminate reflection of waves. The area of the entrance section itself is smoothly reduced before each successive outlet channel by an amount equal to the area of the preceding output channel.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A fluidic pulse and flow divider, which comprises: a. a constant depth input channel having a receiving portion which has a constant area along its length for receiving a steady fluid flow and an output portion; b. a plurality of constant depth output channels located at said output portion of said input channel; c. each of said output channels juxtaposed at the same acute angle with respect to the axis defining the flow path of said steady fluid flow; and d. said constant area of said receiving portion of said input channel being essentially equal to the combined total area of said plurality of output channels.
Claim 2
Dependent Claim
106 words
A fluidic pulse and flow divider, which comprises: a. a constant depth input channel having a receiving portion which has a constant area along its length for receiving a steady fluid flow and an output portion; b. a plurality of constant depth output channels located at said output portion of said input channel; c. each of said output channels juxtaposed at the same acute angle with respect to the axis defining the flow path of said steady fluid flow; and d. said constant area of said receiving portion of said input channel being essentially equal to the combined total area of said plurality of output channels.
Claim 3
Dependent Claim
40 words
The fluidic pulse and flow divider of claim 1 wherein the area of said output portion of said input channel is smoothly reduced before each successive outlet channel by an amount equal to the area of the preceding output channel.
Claim 4
Dependent Claim
42 words
The fluidic pulse and flow divider of claim 2 wherein the portion of each output channel that defines the downstream edge thereof projects into said output portion of said input channel a distance equal to one-half the width of said output channel.
Claim 5
Dependent Claim
23 words
The fluidic pulse and flow divider of claim 2 wherein the shape of the areas of said input and output channels is rectangular.
Claim 6
Dependent Claim
79 words
The fluidic pulse and flow divider of claim 4 wherein one wall boundary of said output portion of said input channel is co-linear and a continuation of one wall boundary of said receiving portion of said input channel while tHe other wall boundary of said output portion comprises a plurality of sections separated by said output channels, said other wall boundary of said output portion being at an oblique angle to the other wall boundary of said receiving portion.
Claim 7
Dependent Claim
31 words
The fluidic pulse and flow divider of claim 5 wherein said output channels are also juxtaposed at said oblique angle with respect to said other wall boundary of said receiving portion.
Claim 8
Dependent Claim
35 words
The fluidic pulse and flow divider of claim 5 wherein said output channels are juxtaposed at a different oblique angle than said oblique angle with respect to said other wall portion of said receiving portion.
Claim 9
Dependent Claim
44 words
The fluidic pulse and flow divider of claim 7 wherein said different oblique angle is such that the downstream edge of each output channel projects into said output portion of said input channel a distance equal to one-half the width of said output channel.
