Abstract

Abstract New and improved fluid supply control method and apparatus for periodic fluid merger which are particularly adapted to the periodic, precisely timed introduction of precisely and uniformly sized fluid segments into a fluid stream are disclosed and comprise a segmenting fluid supply line which respectively connects with a pressurized source of said segmenting fluid at substantially constant pressure and with the line in which said fluid stream is flowing. First and second, quick-acting flow interrupting means are operatively associated with said fluid supply line at spaced locations thereon, and a cavity of substantially constant volume is formed between said flow interrupting means. In operation, and for the formation of each of said segments, said first flow interrupting means are opened to effect the filling of said cavity with said pressurized fluid whereupon said first flow interrupting means are closed and said second flow interrupting means opened to effect the flow of said pressurized fluid from said cavity into said fluid stream to form said segments. A form of the invention is disclosed wherein said fluid supply line is constituted by a compressible, resilient tube and said flow interrupting means comprise means to compress and close said tube at spaced locations thereon. In this disclosed form, the cavity is formed by the volume of the tube which extends between said flow interrupting means.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 229 words
In fluid supply control apparatus for the introduction of a fluid into a fluid stream, the improvements comprising, a fluid supply line of compressible resilient material and having the outlet thereof operatively connected with the line in which said fluid stream is flowing, a pressurized source of the fluid to be introduced, said source being operatively connected with the inlet of said fluid supply line, first and second flow interrupting means operatively associated with said fluid supply line at spaced points thereon, said first flow interrupting means being located between said fluid source and said second flow interrupting means, a cavity of substantially constant volume formed between said first and second flow interrupting means, and means to operate said flow interrupting means to open said first flow interrupting means to enable the filling of said cavity with fluid from said source, to then re-close said first flow interrupting means and open said second flow interrupting means to enable the flow of said fluid from said cavity for iNtroduction into said fluid stream, and to then re-close said second flow interrupting means, said first and second flow interrupting means comprising first and second arm members, respectively, which are independently and pivotally moveable between a first or operative position to compress and close said fluid supply line and a second or inoperative position to release and open said fluid supply line.
Claim 2
Dependent Claim 229 words
In fluid supply control apparatus for the introduction of a fluid into a fluid stream, the improvements comprising, a fluid supply line of compressible resilient material and having the outlet thereof operatively connected with the line in which said fluid stream is flowing, a pressurized source of the fluid to be introduced, said source being operatively connected with the inlet of said fluid supply line, first and second flow interrupting means operatively associated with said fluid supply line at spaced points thereon, said first flow interrupting means being located between said fluid source and said second flow interrupting means, a cavity of substantially constant volume formed between said first and second flow interrupting means, and means to operate said flow interrupting means to open said first flow interrupting means to enable the filling of said cavity with fluid from said source, to then re-close said first flow interrupting means and open said second flow interrupting means to enable the flow of said fluid from said cavity for iNtroduction into said fluid stream, and to then re-close said second flow interrupting means, said first and second flow interrupting means comprising first and second arm members, respectively, which are independently and pivotally moveable between a first or operative position to compress and close said fluid supply line and a second or inoperative position to release and open said fluid supply line.
Claim 3
Dependent Claim 35 words
In apparatus as in claim 1 wherein, said flow interrupting means comprise biasing means operatively connected to said first and second arm members and operable to bias the same to the respective operative positions thereof.
Claim 4
Dependent Claim 36 words
In apparatus as in claim 2 wherein, said flow interrupting means operating means comprise cam means operatively associated with said first and second arm members and operable to drive the same to said inoperative positions thereof.
Claim 5
Dependent Claim 27 words
In apparatus as in claim 3 wherein, said cavity is formed by the volume of the length of said tube which extends between said spaced tube locations.
Claim 6
Dependent Claim 12 words
In apparatus as in claim 4 wherein, said material is silicone rubber.
Claim 7
Dependent Claim 36 words
In apparatus as in claim 1 wherein, said flow interrupting means operating means comprise cam means operatively associated with said first and second arm members and operable to drive the same to said inoperative positions thereof.
Claim 8
Dependent Claim 27 words
In apparatus as in claim 1 wherein, said cavity is formed by the volume of the length of said tube which extends between said spaced tube locations.
