Abstract
Abstract A separator for use in a pipe for separating different fluids within different axial sections of the pipe while enabling the different fluids to be simultaneously moved through the pipe. The separator includes a pair of substantially spherical hollow elastic bodies which are fixedly connected together by intermediate resiliently flexible wall means for permitting the bodies to deflect or bend relative to one another when passing through a curved pipe section. The spherical bodies each have an opening for providing communication between the pipe and the interior of the body whereby the fluid within the pipe deforms the elastic bodies into slideable sealing engagement with the internal wall of the pipe.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A separator adapted to be movably disposed with a pipeline for axially separating different fluids which are being simultaneously moved through the pipe, said separator comprising a pair of adjacent substantially spherical parts constructed of an elastic material and secured together in side-by-side adjoining relationship, said parts each being substantially hollow to define an internal chamber therein, said chambers being open at their opposite ends and closed at their adjacent ends so that the respective fluids can enter the chambers to deform same into snug sliding and sealing contact with the internal wall of the pipe, the external walls of said parts defining an external annular groove at the juncture of said parts to permit flexing of said parts relative to each other.
Claim 2
Dependent Claim
123 words
A separator adapted to be movably disposed with a pipeline for axially separating different fluids which are being simultaneously moved through the pipe, said separator comprising a pair of adjacent substantially spherical parts constructed of an elastic material and secured together in side-by-side adjoining relationship, said parts each being substantially hollow to define an internal chamber therein, said chambers being open at their opposite ends and closed at their adjacent ends so that the respective fluids can enter the chambers to deform same into snug sliding and sealing contact with the internal wall of the pipe, the external walls of said parts defining an external annular groove at the juncture of said parts to permit flexing of said parts relative to each other.
Claim 3
Dependent Claim
13 words
A separator according to claim 1, wherein the openings are substantially coaxially aligned.
Claim 4
Dependent Claim
23 words
A separator according to claim 1, wherein said pair of spherical parts are separable, and including releasable fastening means fixedly connecting said parts.
Claim 5
Dependent Claim
26 words
A separator according to claim 1, wherein said spherical parts are secured together by integral intermediate wall means whereby said separator comprises a one-piece monolithic member.
Claim 6
Dependent Claim
20 words
A separator according to claim 1, wherein a filler member is loosely fitted within at least one of said chambers.
Claim 7
Dependent Claim
68 words
A separator according to claim 1 disposed within a pipe, wherein said spherical parts have a cross sectional diameter substantially equal to the internal diameter of the pipe, and wherein the fluids disposed within the pipe pass through the openings into the internal chambers for causing the elastic spherical parts to radially expand to create a tight sliding and sealing engagement with the internal walls of the pipe.
Claim 8
Dependent Claim
28 words
A separator according to claim 6, wherein said separator, creates two axially spaced, annular areas disposed in sealing and sliding engagement with the internal wall of said pipe.
Claim 9
Dependent Claim
20 words
A separator according to claim 1, wherein the separator, in longitudinal cross-section, has substantially the shape of a figure eight.
