Abstract
Abstract A fluid distributing conduit for conveying fluid under pressure to materials confined within a process vessel includes a feed pipe having a series of holes and a cylindrical elongated member extending along its outer surface over the holes. A plastic coarse-mesh sleeve surrounds the feed pipe and the elongated member, and a fine-mesh fabric sleeve surrounds the coarse-mesh sleeve, whereby the fluid is evenly distributed from the holes to the materials in the vessel. The elongated member spaces the sleeves from the holes to prevent the sleeves from blocking the holes. An elastic band surrounds the pipe over a larger hole to act as a check valve.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
229 words
A conduit assembly for controlling the transfer of liquid between a processing vessel and an associated system, the vessel containing a comminuted material and said conduit assembly being located in said vessel in contact with said comminuted material, the combination comprising: an elongated pipe provided therein with a plurality of spacedapart holes, the spacing of said holes and the cross-sectional area thereof being accurately dimensioned; a seamless, tubular spacer member disposed directly over said pipe in direct contact therewith and beiNg formed by a first plurality of helical bars engaging said pipe substantially throughout the respective lengths of said bars, and a second plurality of bars interconnecting said first plurality of bars and spaced from said pipe by said first plurality of bars, whereby said first plurality of bars may overlie one or more of said holes; a sleeve of filtering material enclosing said spacer member to permit the passage of fluid through said spacer while inhibiting the passage of said comminuted material into said pipe; and said pipe being further provided with depressed annular areas surrounding each of said holes and dimensioned to provide circular passageways communicating with said accurately dimensioned holes and to substantially space said first plurality of bars from said accurately dimensioned portions of said holes, thereby to minimize the effect of said first plurality of bars on the flow of fluid through said holes.
Claim 2
Dependent Claim
229 words
A conduit assembly for controlling the transfer of liquid between a processing vessel and an associated system, the vessel containing a comminuted material and said conduit assembly being located in said vessel in contact with said comminuted material, the combination comprising: an elongated pipe provided therein with a plurality of spacedapart holes, the spacing of said holes and the cross-sectional area thereof being accurately dimensioned; a seamless, tubular spacer member disposed directly over said pipe in direct contact therewith and beiNg formed by a first plurality of helical bars engaging said pipe substantially throughout the respective lengths of said bars, and a second plurality of bars interconnecting said first plurality of bars and spaced from said pipe by said first plurality of bars, whereby said first plurality of bars may overlie one or more of said holes; a sleeve of filtering material enclosing said spacer member to permit the passage of fluid through said spacer while inhibiting the passage of said comminuted material into said pipe; and said pipe being further provided with depressed annular areas surrounding each of said holes and dimensioned to provide circular passageways communicating with said accurately dimensioned holes and to substantially space said first plurality of bars from said accurately dimensioned portions of said holes, thereby to minimize the effect of said first plurality of bars on the flow of fluid through said holes.
Claim 3
Dependent Claim
170 words
A fluid distributor and collector assembly for use in a processing vessel for removing fluid at a first rate from said vessel and for feeding fluid to said vessel at a second rate with said second rate substantially exceeding said first rate, said assembly comprising: a closed end feed pipe having a plurality of apertures therein and a fine-mesh sleeve surrounding the pipe; said feed pipe having a plurality of annular ridges and annular furrows, said apertures being disposed at the innermost portion of said furrows; and a resilient band disposed between said sleeve and said pipe and surrounding said pipe over at least one of said apertures to block said at least one of said apertures and to move outwardly away from blocking relationship therewith by said processing fluid under pressure to permit said fluid to flow outwardly from said at least one of said apertures the flow of said fluid; the number of said last mentioned apertures and the area thereof being selected to accommodate said second rate.
Claim 4
Dependent Claim
170 words
A fluid distributor and collector assembly for use in a processing vessel for removing fluid at a first rate from said vessel and for feeding fluid to said vessel at a second rate with said second rate substantially exceeding said first rate, said assembly comprising: a closed end feed pipe having a plurality of apertures therein and a fine-mesh sleeve surrounding the pipe; said feed pipe having a plurality of annular ridges and annular furrows, said apertures being disposed at the innermost portion of said furrows; and a resilient band disposed between said sleeve and said pipe and surrounding said pipe over at least one of said apertures to block said at least one of said apertures and to move outwardly away from blocking relationship therewith by said processing fluid under pressure to permit said fluid to flow outwardly from said at least one of said apertures the flow of said fluid; the number of said last mentioned apertures and the area thereof being selected to accommodate said second rate.
Claim 5
Dependent Claim
28 words
The combination according to claim 2, further including a coarse-mesh reticulate sleeve surrounding said pipe and said band and being disposed between said band and said fine-mesh sleeve.
Claim 6
Dependent Claim
21 words
The combination according to claim 2, wherein the last-mentioned aperture is relatively larger in area than other ones of said apertures.
