Abstract

Abstract A light weight filament wound pressure vessel. The vessel includes a central cylindrical shell and a pair of end caps adapted to fit into the opposite ends of the shell. Each of the end caps includes a convex, dome-like upper portion, a cylindrical skirt depending from the upper portion and integrally connected thereto, and an annular land connected to the edge of the cylindrical skirt. The cylindrical skirts are of substantially the same outer diameter as the central shell. The lands have an outer diameter which is slightly less than the inner diameter of the central shell so that the junction between the lands and the skirt forms a shoulder having a radial dimension substantially equal to the thickness of the central shell. Each land has an annular groove therein for carrying a resilient O-ring. The O-rings are of a slightly larger diameter than the outer diameter of the lands so that they sealingly engage the inner wall of the central shell when the lands are inserted into the central shell. The central shell and cylindrical skirts of the end caps form a smooth external junction. The assembly is overwound with a fiberglass filament to provide the desired bursting strength of the vessel. The lands may be integrally connected to the skirts or mounted on a collector ring. In one embodiment of the pressure vessel of this invention a fluid flow directing means is integrally connected to the internal surfaces of one of the end caps for guiding fluids through the vessel and eliminating ''''channeling.'''' This embodiment of the invention is particularly adapted for use as a water conditioning tank.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 61 words
In combination with a pressure vessel having interiorly thereof a cylindrical wall component, the improvement which comprises: means for directing fluid flow including a plurality of bifurcated vanes defining radially extending curved fluid flow channels which terminate substantially tangentially to the inner surfaces of said cylindrical wall component to cause said fluids to pass out of said channels under high turbulence.
Claim 2
Dependent Claim 61 words
In combination with a pressure vessel having interiorly thereof a cylindrical wall component, the improvement which comprises: means for directing fluid flow including a plurality of bifurcated vanes defining radially extending curved fluid flow channels which terminate substantially tangentially to the inner surfaces of said cylindrical wall component to cause said fluids to pass out of said channels under high turbulence.
Claim 3
Dependent Claim 32 words
A combination as defined in claim 1 wherein said channels decrease in cross-sectional area from the center portion of said cylindrical wall component outwardly to accelerate the rate of fluid flow therethrough.
Claim 4
Dependent Claim 43 words
A combination as defined in claim 1 wherein said vanes define chambers intermediate said channels and further comprising closure means over said channels for causing fluids passing through said channels to flow from said chambers into the interior of said cylindrical wall component.
Claim 5
Dependent Claim 73 words
A combination as defined in claiM 3 wherein said closure means comprises a collector disc mounted on the upper edge of said vanes, said collector disc having radially spaced openings therein in the portions of said disc which extend over said chambers, said openings being formed to vary in capacity from the central portion of said cylindrical wall component to the outer portions thereof with the highest capacity openings adjacent said outer portions.
Claim 6
Dependent Claim 151 words
A fluid conditioning tank assembly for use in treating a fluid by contacting it with a fluid conditioning media comprising: a cylindrical shell having at least one dome-like convex end; a hollow conduit entering the tank through one of its ends and extending through said cylindrical shell and terminating in a dome-like convex other end for transmitting fluids through said tank; fluid flow directing means defining a plurality of paths for fluid flow from the center of the dome-like convex end in which the hollow conduit terminates radially outwardly to the side walls of that dome-like convex end; and means connected to the dome-like convex end in which said hollow conduit terminates for restricting fluid flow between that dome-like convex end and said shell so that the resistance to fluid flow between that dome-like convex end and said shell decreases with the radial distance from the axis of said conditioning tank.
Claim 7
Dependent Claim 151 words
A fluid conditioning tank assembly for use in treating a fluid by contacting it with a fluid conditioning media comprising: a cylindrical shell having at least one dome-like convex end; a hollow conduit entering the tank through one of its ends and extending through said cylindrical shell and terminating in a dome-like convex other end for transmitting fluids through said tank; fluid flow directing means defining a plurality of paths for fluid flow from the center of the dome-like convex end in which the hollow conduit terminates radially outwardly to the side walls of that dome-like convex end; and means connected to the dome-like convex end in which said hollow conduit terminates for restricting fluid flow between that dome-like convex end and said shell so that the resistance to fluid flow between that dome-like convex end and said shell decreases with the radial distance from the axis of said conditioning tank.
Claim 8
Dependent Claim 64 words
A fluid conditioning tank as defined in claim 5 wherein said fluid flow path defining means comprise a plurality of upstanding bifurcated vanes having curved radially extending arm portions thereon, said vanes being substantially symmetrically arranged about the center of the dome-like convex end in which the hollow conduit terminates and spaced from each other to define a plurality of fluid channels and chambers.
Claim 9
Dependent Claim 104 words
A fluid conditioning tank as defined in claim 6 wherein said means for restricting fluid flow between said shell and the dome-like convex end in which said hollow conduit terminates comprises a collector disc member fitted over said conduit in substantially fluid tight relationship therewith and mounted on the upstanding edges of said vanes in substantially fluid tight relationship with the wall of that dome-like convex end; said disc member having radially spaced openings in the portions of said disc member extending over said chambers for restricting to the openings in said disc member fluid flow between said shell and that dome-like convex end.
Claim 10
Dependent Claim 40 words
A fluid conditioning tank as defined in claim 6 including means in the dome-like convex end in which said hollow conduit terminates for providing limited direct fluid flow from said chambers to the center portion of that dome-like convex end.
