Abstract
Abstract A separator for separating low and high density constituents of a liquid includes a tank. The tank has a liquid inlet, an opposing liquid outlet and an upper side drain. A filter is mounted in the tank adjacent the inlet for filtering its discharging liquids. An input dam is located downstream of the filter and extends upward a given height. The drain is positioned to draw from locations downstream of the dam. In one embodiment, the tank has a top panel extending across the tank, its upper edge near the drain. The panel is inclined upwardly to cause an upward liquid flow. An internal baffle may be mounted across the tank between the the outlet and the panel. This baffle is spaced from the bottom of the tank to provide an upwardly accelerating liquid flow.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
A separator for separating low and high density constituents of a liquid, comprising: a tank having a liquid inlet, an opposing liquid outlet, a top panel extending across said tank and an upper drain near the upper edge of said panel, said panel being inclined upwardly to cause an upward liquid flow; an internal baffle having an upstream and downstream side mounted across said tank between said outlet and said panel, said drain opening exclusively on said upstream side of said baffle, said baffle being spaced from the bottom of said tank to produce at said downstream side an upwardly accelerating liquid flow away from said drain; a filter means affixed adjacent said inlet for filtering its discharging liquid, said tank having between said filter means and said inlet a lower opening; an input and output dam mounted in said tank, each being spaced from the top of said tank, said outlet being spaced below the top of said output dam, whereby liquid cascades over said output dam; and a pair of spaced, upstream baffles mounted in said tank upstream of said internal baffle, said upstream baffles being tilted backwards.
Claim 2
Dependent Claim
190 words
A separator for separating low and high density constituents of a liquid, comprising: a tank having a liquid inlet, an opposing liquid outlet, a top panel extending across said tank and an upper drain near the upper edge of said panel, said panel being inclined upwardly to cause an upward liquid flow; an internal baffle having an upstream and downstream side mounted across said tank between said outlet and said panel, said drain opening exclusively on said upstream side of said baffle, said baffle being spaced from the bottom of said tank to produce at said downstream side an upwardly accelerating liquid flow away from said drain; a filter means affixed adjacent said inlet for filtering its discharging liquid, said tank having between said filter means and said inlet a lower opening; an input and output dam mounted in said tank, each being spaced from the top of said tank, said outlet being spaced below the top of said output dam, whereby liquid cascades over said output dam; and a pair of spaced, upstream baffles mounted in said tank upstream of said internal baffle, said upstream baffles being tilted backwards.
Claim 3
Dependent Claim
29 words
a separator according to claim 1 wherein said panel has an upwardly inclining portion and wherein said internal baffle and said upwardly inclining portion of said panel are contiguous.
Claim 4
Dependent Claim
20 words
A separator according to claim 1 wherein said upstream baffles are spaced from the top and bottom of said tank.
Claim 5
Dependent Claim
50 words
A separator according to claim 1 wherein said input dam has a notched upper edge mounted in said tank between said filter means and said internal baffle, said input dam further comprising: an input gate slidably mounted on said input dam to cover said notched upper edge an adjustable amount.
Claim 6
Dependent Claim
68 words
A separator according to claim 1 or 4 wherein said output dam has a notched upper edge mounted in said tank downstream of said internal baffle, said output dam further comprising: an output gate slidably mounted on said output dam to cover said notched upper edge an adjustable amount, said outlet being spaced below the top of said output dam whereby cascading of liquid occurs over said gate.
Claim 7
Dependent Claim
71 words
A separator according to claim 1 wherein said inlet comprises: a pair of spaced ports; an input line; and a commutating valve for feeding said input line to either one of said ports, said filter means comprising a pair of adjacent catches, each positioned to filter liquid discharging from a different corresponding one of said ports, both of said catches commonly communicating to said drain, said outlet and said internal baffle.
