Abstract
Abstract Separator for immiscible fluids having a closed end and an outlet spaced along an axis, a separating medium arranged with inlet and outlet faces generally parallel to the axis so that fluid having passed through the medium flows along the axis toward the outlet, and a multiplicity of flow-directing surfaces arranged adjacent one of said faces to direct fluid entering said separator in a direction having a component along said axis toward said closed end.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
89 words
A fluid separator comprising a closed end and an outlet spaced along an axis, a separating medium arranged with inlet and outlet faces generally parallel to said axis so that fluid having passed through said medium flows along said axis toward said outlet, and a multiplicity of flow-directing portions secured to structure fixed with respect to said closed end and arranged adjacent one of said faces to direct fluid entering said separator so as to have a velocity having a component directed along said axis toward said closed end.
Claim 2
Dependent Claim
89 words
A fluid separator comprising a closed end and an outlet spaced along an axis, a separating medium arranged with inlet and outlet faces generally parallel to said axis so that fluid having passed through said medium flows along said axis toward said outlet, and a multiplicity of flow-directing portions secured to structure fixed with respect to said closed end and arranged adjacent one of said faces to direct fluid entering said separator so as to have a velocity having a component directed along said axis toward said closed end.
Claim 3
Dependent Claim
16 words
The separator of claim 1 wherein said flow directing portions are flaps of a louvered tube.
Claim 4
Dependent Claim
24 words
The separator of claim 2 wherein said tube is a cylindrical centertube which at least partially supports and is radially inward of said medium.
Claim 5
Dependent Claim
20 words
The separator of claim 2 wherein said tube has generally rectangular openings with their largest dimension parallel to said axis.
Claim 6
