Abstract
Abstract Provided is a distribution system for the uniform distribution of fluids. The system comprises a conduit means which has an inlet for supplying fluid under pressure to the interior of the conduit means. Outlet means are distributed along the length of the conduit for lateral discharge of the fluid from the conduit, and means for increasing the interior surface roughness of the conduit, such as a stainless steel screen, is attached to the inner surface of the conduit opposite the outlet means. The resulting distribution system achieves a uniform distribution of fluid easily and inexpensively.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
124 words
A distribution system for fluids comprising: (a) conduit means; (b) inlet means for supplying fluid under pressure to the interior of said conduit means; (c) conduit outlet means distributed along the length of the conduit for laterally discharging the fluid from the conduit; and (d) means for increasing the interior surface roughness of the conduit sufficiently to result in the uniform distribution of fluid through the conduit outlet means when the fluid is passed through the conduit under turbulent flow conditions, which means is positioned on the inner surface of the conduit opposite the conduit outlet means such that a fluid passing through the conduit does not have to pass in contact with said means immediately prior to passing through the conduit outlet means.
Claim 2
Dependent Claim
124 words
A distribution system for fluids comprising: (a) conduit means; (b) inlet means for supplying fluid under pressure to the interior of said conduit means; (c) conduit outlet means distributed along the length of the conduit for laterally discharging the fluid from the conduit; and (d) means for increasing the interior surface roughness of the conduit sufficiently to result in the uniform distribution of fluid through the conduit outlet means when the fluid is passed through the conduit under turbulent flow conditions, which means is positioned on the inner surface of the conduit opposite the conduit outlet means such that a fluid passing through the conduit does not have to pass in contact with said means immediately prior to passing through the conduit outlet means.
Claim 3
Dependent Claim
55 words
The distribution system of claim 1, wherein the means for increasing the interior surface roughness is a screen attached to the inner surface of the conduit opposite the conduit outlet means, such that a fluid passing through the conduit does not have to pass through the screen immediately prior to passing through the outlet means.
Claim 4
Dependent Claim
14 words
The distribution system of claim 2, wherein the screen is a stainless steel screen.
Claim 5
Dependent Claim
20 words
The distribution system of claim 2, wherein the conduit outlet means are uniformly distributed along the length of the conduit.
Claim 6
Dependent Claim
16 words
The distribution system of claim 2, wherein the conduit means is of substantially uniform cross-sectional area.
Claim 7
Dependent Claim
14 words
The distribution system of claim 2, wherein the conduit means is a pipe distributor.
Claim 8
Dependent Claim
127 words
A manifold for the uniform distribution of steam, comprising: (a) a manifold with inlet means for supplying steam under pressure to the interior of the manifold; (b) outlet means distributed along the length of the manifold for lateral discharge of the steam; and (c) a screen attached to the inner surface of the manifold opposite the outlet means, such that the steam passing through the manifold does not have to pass through the screen immediately prior to passing through the outlet means, with the screen being of sufficient size and mesh no. such that the interior surface roughness of the conduit is increased sufficiently to achieve a uniform distribution of steam through the outlet means when the steam is passed through the manifold under turbulent flow conditions.
Claim 9
Dependent Claim
127 words
A manifold for the uniform distribution of steam, comprising: (a) a manifold with inlet means for supplying steam under pressure to the interior of the manifold; (b) outlet means distributed along the length of the manifold for lateral discharge of the steam; and (c) a screen attached to the inner surface of the manifold opposite the outlet means, such that the steam passing through the manifold does not have to pass through the screen immediately prior to passing through the outlet means, with the screen being of sufficient size and mesh no. such that the interior surface roughness of the conduit is increased sufficiently to achieve a uniform distribution of steam through the outlet means when the steam is passed through the manifold under turbulent flow conditions.
Claim 10
Dependent Claim
13 words
The manifold of claim 7, wherein the screen is a stainless steel screen.
Claim 11
Dependent Claim
14 words
The manifold of claim 8, wherein the manifold is of substantially uniform cross-sectional area.
Claim 12
Dependent Claim
74 words
A process for the uniform distribution of a fluid which is passed through a conduit, comprising the steps of (a) providing a conduit having outlet means distributed along its length for laterally discharging the fluid from the conduit, said conduit comprising means for increasing its interior surface roughness sufficiently to result in the uniform distribution of fluid through the outlet means, and (b) providing a fluid to the conduit under conditions of turbulent flow.
Claim 13
Dependent Claim
74 words
A process for the uniform distribution of a fluid which is passed through a conduit, comprising the steps of (a) providing a conduit having outlet means distributed along its length for laterally discharging the fluid from the conduit, said conduit comprising means for increasing its interior surface roughness sufficiently to result in the uniform distribution of fluid through the outlet means, and (b) providing a fluid to the conduit under conditions of turbulent flow.
Claim 14
Dependent Claim
53 words
The method of claim 10, wherein the means for increasing interior surface roughness of the conduit provided is a screen attached to the inner surface of the conduit opposite the outlet means, such that the fluid does not have to pass through the screen immediately prior to passing through the conduit outlet means.
Claim 15
Dependent Claim
13 words
The method of claim 11, wherein the screen is a stainless steel screen.
