Abstract
Abstract Fluidic elements are formed of pie-shaped segments in which the major ducts are formed in the edge of the pie-shaped segments. The ducts can be formed by milling, coining, stamping or molding, since their depth is normally one-fourth that of their width. The respective segments are assembled into a circular plate and inserted in a suitable containing structure.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
The method of constructing a fluidic device having an inlet duct, outlet ducts and control ducts which comprises the process of: a. dividing a proposed device into a plurality of pie-shaped segments bounded by the said ducts of said device and adapted to be bound together to form the complete element; b. forming ducts in an intermediate portion of an edge along the respective segments; c. separating the outlet ducts of the element by a splitting segment having ducts formed in the sides thereof and having a splitting edge of approximately 30* facing inwardly thereof; and d. assembling the plurality of segments together.
Claim 2
Independent Claim
103 words
The method of constructing a fluidic device having an inlet duct, outlet ducts and control ducts which comprises the process of: a. dividing a proposed device into a plurality of pie-shaped segments bounded by the said ducts of said device and adapted to be bound together to form the complete element; b. forming ducts in an intermediate portion of an edge along the respective segments; c. separating the outlet ducts of the element by a splitting segment having ducts formed in the sides thereof and having a splitting edge of approximately 30* facing inwardly thereof; and d. assembling the plurality of segments together.
Claim 3
Dependent Claim
32 words
The method of claim 1 wherein the inlet duct is formed one-half in the edge of one of said segments and one-half is formed in the adjoining edge of the adjoining segment.
Claim 4
Dependent Claim
55 words
The method of claim 1 wherein the proposed device is divided into four equal segments, the inlet duct is formed equally in the adjoining edges of two of said segments, a control duct is formed in the other edges of said two segments, and the outlet ducts are equally positioned in the remaining two segments.
Claim 5
Dependent Claim
58 words
The method of claim 3 wherein the outlet ducts are formed by forming a duct in each of the remaining two segments, which ducts each form an angle of approximately 15*; and inserting a splitting segment forming an angle of the total value of said two ducts, and forming a duct in each interior wall of said segment.
Claim 6
Independent Claim
139 words
The method of constructing fluidic elements which comprise the process of: a. dividing a proposed device into a plurality of pie-shaped segments adapted to be bound together to form the complete element, b. forming an inlet channel in an intermediate portion of an edge along the wall that separates two of said segments, c. forming outlet channels in the intermediate portion of the edge along the wall that separates two other of said segments, said outlet channels diverging from the center of said device at an angle of about 15* in each segment, d. inserting a tight fitting splitter segment into the cavity formed by the two said outlet channels, and e. forming outlet ducts in the intermediate portion of the edge of a wall that separates the splitter segment from each of the two other of said segments.
Claim 7
Independent Claim
139 words
The method of constructing fluidic elements which comprise the process of: a. dividing a proposed device into a plurality of pie-shaped segments adapted to be bound together to form the complete element, b. forming an inlet channel in an intermediate portion of an edge along the wall that separates two of said segments, c. forming outlet channels in the intermediate portion of the edge along the wall that separates two other of said segments, said outlet channels diverging from the center of said device at an angle of about 15* in each segment, d. inserting a tight fitting splitter segment into the cavity formed by the two said outlet channels, and e. forming outlet ducts in the intermediate portion of the edge of a wall that separates the splitter segment from each of the two other of said segments.
