Abstract
Abstract A separator for separating material from a fluid which includes an inlet, a separating chamber in fluid communication with the inlet, a holding chamber, a deflector for deflecting material entrained in or moving with fluid entering the separating chamber from the inlet towards the holding chamber, and an outlet for permitting flow of fluid from which the material has been removed from the separating chamber.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
112 words
A separator for separating material from a fluid, said separator comprising: a molded body having an inlet, a separating chamber in fluid communication with the inlet, and a holding chamber at least part of which is laterally adjacent to the separating chamber; deflecting means for deflecting material entrained in or moving with fluid entering the separating chamber from said inlet towards said holding chamber; and an outlet for permitting flow of fluid from which said material has been removed from the separating chamber, wherein the deflecting means includes a boom which is mounted in the separating chamber for pivotal movement about an axis which is located between the boom and said inlet.
Claim 2
Dependent Claim
112 words
A separator for separating material from a fluid, said separator comprising: a molded body having an inlet, a separating chamber in fluid communication with the inlet, and a holding chamber at least part of which is laterally adjacent to the separating chamber; deflecting means for deflecting material entrained in or moving with fluid entering the separating chamber from said inlet towards said holding chamber; and an outlet for permitting flow of fluid from which said material has been removed from the separating chamber, wherein the deflecting means includes a boom which is mounted in the separating chamber for pivotal movement about an axis which is located between the boom and said inlet.
Claim 3
Dependent Claim
28 words
A separator as claimed in claim 1 wherein a lower part of the holding chamber is at a lower level relative to the separating chamber and said outlet.
Claim 4
Dependent Claim
23 words
A separator as claimed in claim 1 including a screen to prevent floating bodies in the holding chamber from re-entering the separating chamber.
Claim 5
Dependent Claim
31 words
A separator as claimed in claim 1 including a baffle extending transversely across the holding chamber, the baffle having a lower edge which is lower than the level of said outlet.
Claim 6
Dependent Claim
29 words
A separator as claimed in claim 1 wherein the separating chamber includes an oil deflecting strip which operates tc prevent oil seeping from the separating chamber to said outlet.
Claim 7
Dependent Claim
17 words
A separator as claimed in claim 1 wherein the boom has a specific gravity less than 1.
Claim 8
Dependent Claim
14 words
A separator as claimed in claim 6 wherein the specific gravity is about 0.8.
Claim 9
Dependent Claim
35 words
A separator as claimed in claim 6 wherein when said fluid comprises water and the boom is normally supported by a floor of the separating chamber until the boom is submerged by a predetermined amount.
Claim 10
Dependent Claim
24 words
A separator as claimed in claim 7 wherein said amount is a depth of 50% to 80% of a vertical dimension of the boom.
Claim 11
Dependent Claim
22 words
A separator as claimed in claim 1 wherein said axis is inclined relative to the direction of fluid movement in said inlet.
Claim 12
Dependent Claim
21 words
A separator as claimed in claim 1 wherein the boom includes a curved frontal face which is directed towards said inlet.
Claim 13
Dependent Claim
35 words
A separator as claimed in claim 11 wherein said axis is transverse to the direction of fluid movement in said inlet and said curvature of said frontal face varies along the length of the boom.
Claim 14
Dependent Claim
42 words
A separator as claimed in claim 12 wherein the variation of curvature is such that the effective inclination of the frontal face at the water line of water within the separating chamber increases as the water level in the separating chamber increases.
Claim 15
Dependent Claim
38 words
A separator as claimed in claim 3 wherein the screen forms part of a curtain wall and wherein said boom is mounted by means of arms at least one of which is pivotally connected to said curtain wall.
Claim 16
Dependent Claim
17 words
A separator as claimed in claim 14 wherein the arms are pivotally mounted upstream of said boom.
Claim 17
Dependent Claim
14 words
A separator as claimed in claim 10 wherein the axis is above the boom.
Claim 18
Dependent Claim
126 words
A separator for separating material from a fluid, said separator comprising: an inlet; a separating chamber in fluid communication with the inlet; a holding chamber; deflecting means for deflecting material entrained in or moving with fluid entering the separating chamber from said inlet towards said holding chamber; and an outlet for permitting flow of fluid from which said material has been removed from the separating chamber, wherein the deflecting means comprises a boom which is mounted in said separating chamber for pivotal movement about an axis which is transverse relative to the direction of fluid movement in said inlet, the boom includes a curved frontal face which is directed towards said inlet, and the curvature of the frontal face varies along the length of the boom.

Claim 20
Dependent Claim
42 words
A separator as claimed in claim 17 wherein the variation of curvature is such that the effective inclination of the frontal face at the water line of water within the separating chamber increases as the water level in the separating chamber increases.
