Abstract
Abstract A simple and efficient flow regulator for controlling the discharge from adjoining collecting chambers separated by a partition and including a common wall which includes a disc mounted in the side wall. The axis of rotation of the disc is in general aligned with the partition and the disc includes an opening asymmetrically disposed relative to the axis of rotation. Thus upon rotation of the disc the area of the opening communicating with each chamber is varied to vary the ratio of discharge flow from each chamber. Details of the structure and mounting are described.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
In a flow regulator for the sediment discharge from two adjoining hopper-shaped sediment collecting chambers, wherein a substantially vertical partition separates the collecting chambers, and wherein the collecting chambers include a common side wall at the lower end thereof, the improvement comprising: means forming an opening in said side wall and communicating with each chamber separated by the vertical partition, rotatable disc means mounted in said side wall adjacent to the partition, the partition extending at least the full diameter of said disc, means forming an opening in said disc, the axis of rotation of the disc being in general alignment with the partition, the opening in said disc being asymmetrically disposed relative to the axis of rotation, the opening in the side wall being larger than the opening in the disc such that upon rotation of the disc the opening in the disc remains within the opening of the side wall, said disc including means to effect rotation thereof in the opening of said side wall, and rotation of the disc being operative to vary the area of the opening communicating with each chamber whereby the ratio of discharge flow may be varied.
Claim 2
Dependent Claim
194 words
In a flow regulator for the sediment discharge from two adjoining hopper-shaped sediment collecting chambers, wherein a substantially vertical partition separates the collecting chambers, and wherein the collecting chambers include a common side wall at the lower end thereof, the improvement comprising: means forming an opening in said side wall and communicating with each chamber separated by the vertical partition, rotatable disc means mounted in said side wall adjacent to the partition, the partition extending at least the full diameter of said disc, means forming an opening in said disc, the axis of rotation of the disc being in general alignment with the partition, the opening in said disc being asymmetrically disposed relative to the axis of rotation, the opening in the side wall being larger than the opening in the disc such that upon rotation of the disc the opening in the disc remains within the opening of the side wall, said disc including means to effect rotation thereof in the opening of said side wall, and rotation of the disc being operative to vary the area of the opening communicating with each chamber whereby the ratio of discharge flow may be varied.
Claim 3
Dependent Claim
17 words
A regulator as set forth in claim 1 wherein the opening in the side wall is circular.
Claim 4
Dependent Claim
21 words
A regulator as set forth in claim 1 wherein the opening in the wall is symmetrical with respect to the partition.
Claim 5
Dependent Claim
16 words
A regulator as set forth in claim 1 wherein the opening in the disc is circular.
Claim 6
Dependent Claim
23 words
A regulator as set forth in claim 1 wherein the opening in the disc is outside the axis of rotation of the disc.
Claim 7
Dependent Claim
36 words
A regulator as set forth in claim 1 further including ring flange means for mounting said disc against said side wall, and said disc being generally circular and being rotatable with respect to said side wall.
Claim 8
Dependent Claim
44 words
A regulator as set forth in claim 6 wherein said ring flange means includes a fixed flange and a spaced movable flange, said disc including a peripheral portion received between said flanges, and means to secure said flanges together thereby to secure said disc.
Claim 9
Dependent Claim
16 words
A regulator as set forth in claim 7 wherein spacer bushings are provided between said flanges.
Claim 10
Dependent Claim
28 words
A regulator as set forth in claim 7 wherein seal means are provided between the disc and the end wall and between the disc and the movable flange.
Claim 11
Dependent Claim
41 words
A regulator as set forth in claim 9 wherein the opening of the end wall and the opening of the fixed flange are chamfered, said disc including shoulders cooperating with adjacent flanges, and sealing means provided between adjacent flanges and shoulders.
