Abstract

Abstract An interconnector for the coaxially adjacent permeate tubes of filtration apparatus comprises a molded elastomeric spheroidal body having opposed coaxial bores for receiving the tube ends which extend from filter membrane modules. Complementarily shaped interdigitated pairs of anti-telescoping devices are interposed between membrane modules in mutual interacting relationship and without contacting the interconnector.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 166 words
A coupling assembly comprising two coaxial conduit members, an interconnector means for coupling and sealing said coaxial members, and wall means defining a pressure chamber around said members adapted to contain a pressurized fluid between said members and said wall means, said interconnector means having a spheroidal body located within said pressure chamber and comprised of elastomeric material, said body having coaxial bores extending into it from opposite sides for receiving the respective ends of said members in a snug fitting relationship, and said body being operative to transmit pressure exerted by the fluid on its outside surface to the surface constituting the interface area between said bores and the members in the bores, the area of said outside surface of the body being substantially larger than said interface area so that the force on a unit area of said interfacing surface is greater than the force exerted by said fluid on a unit area of said outside surface to enhance the seal between said members.
Claim 2
Dependent Claim 166 words
A coupling assembly comprising two coaxial conduit members, an interconnector means for coupling and sealing said coaxial members, and wall means defining a pressure chamber around said members adapted to contain a pressurized fluid between said members and said wall means, said interconnector means having a spheroidal body located within said pressure chamber and comprised of elastomeric material, said body having coaxial bores extending into it from opposite sides for receiving the respective ends of said members in a snug fitting relationship, and said body being operative to transmit pressure exerted by the fluid on its outside surface to the surface constituting the interface area between said bores and the members in the bores, the area of said outside surface of the body being substantially larger than said interface area so that the force on a unit area of said interfacing surface is greater than the force exerted by said fluid on a unit area of said outside surface to enhance the seal between said members.
Claim 3
Dependent Claim 45 words
The interconnector means as in claim 1, including an annular element extending from said body radially inwardly of said bores and having axially spaced apart end surfaces for the ends of the respective members to butt against when said members are in the respective bores.
Claim 4
Dependent Claim 32 words
The interconnector means as in claim 2 wherein said elastomeric material comprising said body and annular element has an indentation hardness of about 60 to 70 on the type A Durometer scale.
Claim 5
Dependent Claim 45 words
The interconnector means as in claim 2 wherein said annular element which extends into said bores is bonded in said body, and said annular element is comprised of an elastomeric material which has a higher durometer than the material of which said body is comprised.
Claim 6
Dependent Claim 44 words
The interconnector means as in claim 4 wherein the body material has a durometer of about 60 to 70 on the type A Durometer scale and the annular element material has a durometer of about 50 to 55 on the type D Durometer scale.
Claim 7
Dependent Claim 24 words
The interconnector means as in any of claims 2, 3, 4 or 5 wherein said body and annular element materials are Buna N rubber.
Claim 8
Dependent Claim 34 words
The interconnector means as in claim 4 including: a metal annulus embedded in said body concentrically with and contiguous with the outer periphery of the elastomeric annular element which is bonded in said body.
