Abstract
Abstract An apparatus for controllably dispersing material into a fluid stream with the apparatus having a housing with a bottom section that attaches to a pipe line and a top section having a cylindrical sleeve with a porous container therein to support a solid fluid soluble material. The porous container can be controllably inserted into a fluid stream through coaction of a spring and cap to control the amount of soluble material entering the fluid stream. A sealing surface on the porous container and the cylindrical sleeve prevents fluid from escaping from the line when the porous container is in the up position and an upper seal prevents leakage past the cap when the valve is in operation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
An inline dispersal valve for controllably releasing material into a fluid line comprising: a housing having a means for attachment to a pressurized fluid line, said housing having an opening therein operable for fluid coupling with fluid in a fluid line; a sleeve located in said housing said sleeve having an opening therein; a porous container slideably mounted in the opening in said sleeve; means for controllably raising or lowering said container into the pressurized fluid line to allow fluid to flow through said container to thereby dissolve soluble solid in said container and transport said dissolved material into the fluid line; and resilient means for maintaining said container in contact with said means for controllably raising or lowering said container.
Claim 2
Dependent Claim
121 words
An inline dispersal valve for controllably releasing material into a fluid line comprising: a housing having a means for attachment to a pressurized fluid line, said housing having an opening therein operable for fluid coupling with fluid in a fluid line; a sleeve located in said housing said sleeve having an opening therein; a porous container slideably mounted in the opening in said sleeve; means for controllably raising or lowering said container into the pressurized fluid line to allow fluid to flow through said container to thereby dissolve soluble solid in said container and transport said dissolved material into the fluid line; and resilient means for maintaining said container in contact with said means for controllably raising or lowering said container.
Claim 3
Dependent Claim
33 words
The invention of claim 1 including coacting sealing surfaces located in said sleeve and said container to thereby prevent fluid from flowing into said container when said container is in the up position.
Claim 4
Dependent Claim
17 words
The invention of claim 2 wherein said sleeve includes means for holding said sleeve in said housing.
Claim 5
Dependent Claim
24 words
The invention of claim 3 wherein said container includes means to prevent rotation of said container during rotation of a cap onto said container.
Claim 6
Dependent Claim
18 words
The invention of claim 4 wherein said container has a recess therein for placing a solid material therein.
Claim 7
Dependent Claim
21 words
The invention of claim 5 wherein said inline dispersal valve includes an extension for increasing the holding capacity of said container.
