Abstract
Abstract A means separates solid matter from liquid and includes a perforated separation panel through which the liquid can pass and which prevents the passage of the solid matter of a size larger than a predetermined size. When solid matter becomes located against the panel, the flow of liquid along the face of the panel on which the solid matter is located will tend to cause the solid matter to move from the panel so that the panel is self cleaned and does not become obstructed by the solid matter.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
208 words
An apparatus for separating solid matter from a liquid stream passing through the apparatus, comprising: a generally cylindrical separation panel surrounding an interior space and which is oriented so as to have a generally upright longitudinal axis, the separation panel having a plurality of vertically and horizontally spaced openings which are adapted to remove solid material larger than a predetermined size from liquid passing through the separation panel; a chamber member surrounding the separation panel and providing a chamber portion into which the liquid passes after passing through the separation panel; an inlet through which the liquid stream is delivered to said interior space and which is arranged such that the liquid circulates about said axis so as to pass said separation panel; and an outlet extending from said chamber portion, the outlet being positioned with respect to the chamber portion so that at least a portion of said panel is submerged, wherein said panel has a plurality of vertically and horizontally spaced deflective segments adjacent the openings and which project inwardly with respect to said space to inhibit particulate matter of at least said predetermined size from blocking said openings by the openings being positioned behind the deflective segments relative to the flow of liquid there passed.
Claim 2
Independent Claim
208 words
An apparatus for separating solid matter from a liquid stream passing through the apparatus, comprising: a generally cylindrical separation panel surrounding an interior space and which is oriented so as to have a generally upright longitudinal axis, the separation panel having a plurality of vertically and horizontally spaced openings which are adapted to remove solid material larger than a predetermined size from liquid passing through the separation panel; a chamber member surrounding the separation panel and providing a chamber portion into which the liquid passes after passing through the separation panel; an inlet through which the liquid stream is delivered to said interior space and which is arranged such that the liquid circulates about said axis so as to pass said separation panel; and an outlet extending from said chamber portion, the outlet being positioned with respect to the chamber portion so that at least a portion of said panel is submerged, wherein said panel has a plurality of vertically and horizontally spaced deflective segments adjacent the openings and which project inwardly with respect to said space to inhibit particulate matter of at least said predetermined size from blocking said openings by the openings being positioned behind the deflective segments relative to the flow of liquid there passed.
Claim 3
Dependent Claim
23 words
An apparatus according to claim 1 , wherein said inlet directs the liquid so as to circulate within said space about said axis.
Claim 4
Dependent Claim
23 words
An apparatus according to claim 2 , further comprising a receptacle which receives particulate matter removed from said stream by said separation panel.
Claim 5
Dependent Claim
15 words
An apparatus according to claim 3 , wherein said receptacle is located below said space.
Claim 6
Dependent Claim
20 words
An apparatus according to claim 4 , wherein said inlet and said outlet are positioned at substantially the same height.
Claim 7
Dependent Claim
16 words
An apparatus according to claim 5 , wherein said inlet and said outlet are substantially aligned.
Claim 8
Dependent Claim
33 words
An apparatus according to claim 6 , wherein said separation panel comprises an inner wall surrounding said interior space and said inlet directs said stream substantially tangentially with respect to said inner wall.
Claim 9
Dependent Claim
28 words
An apparatus according to claim 1 , wherein said panel has an annular upper extremity surrounding said longitudinal axis and said outlet extends from adjacent said upper extremity.
Claim 10
Dependent Claim
28 words
An apparatus according to claim 2 , wherein said panel has an annular upper extremity surrounding said longitudinal axis and said outlet extends from adjacent said upper extremity.
