Abstract
Abstract An immiscible liquid separating apparatus having an adjustable weir which admits a predominant portion of the lighter of the two liquids and a minor portion of the heavier of the two liquids into a first chamber. Liquid in the first chamber may communicate with a second chamber over another adjustable weir to permit the lighter of the two liquids to flow over the top of the second weir into the second chamber. The first chamber is provided with an aspirating slot disposed generally transversely across the bottom of the chamber to permit the heavier of the two liquids admitted to the first chamber to be withdrawn therefrom upon movement of the apparatus through the liquid body. The lighter of the two liquids collected in the second chamber may be removed by pump means disposed within the second chamber or through a line connected to the pump means positioned externally of the chamber.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
278 words
An apparatus for separating two immiscible liquids, which apparatus comprises: a body having side walls which extend downwardly into said liquids and terminate below the interface of the two liquids; a bottom member connecting the side walls beneath the interface of the fluids; a first adjustable weir extending between and positioned transversely of said side walls, the top of said first weir being adapted to be positioned below the interface of the two liquids so a predominant portion of the lighter of the two liquids will flow over said first weir; a second adjustable weir extending transversely of the side walls and forming with the first weir, the side walls and the bottom member a first chamber, the first chamber having an aspirating slot therein which is positioned below the interface of the two fluids and is so shaped that upon movement of said body relative to said liquids a suction will be created at the slot causing the heavier liquid to be withdrawn from said first chamber through said slot; a back wall positioned transversely of said side members and forming with said second weir, said bottom member and said side wall a second chamber in which may be collected the lighter of the two liquids which flows over said second weir; said first weir extends downwardly and rearwardly toward the back wall of said apparatus and defines at its trailing end a substantially horizontal portion; and said bottom member has a leading edge which extends over the trailing end of said first weir to define therewith said aspirating slot through which the heavier of the two liquids may be withdrawn upon forward movement of said apparatus.
Claim 2
Independent Claim

An apparatus for separating two immiscible liquids, which apparatus comprises: a body having side walls which extend downwardly into said liquids and terminate below the interface of the two liquids; a bottom member connecting the side walls beneath the interface of the fluids; a first adjustable weir extending between and positioned transversely of said side walls, the top of said first weir being adapted to be positioned below the interface of the two liquids so a predominant portion of the lighter of the two liquids will flow over said first weir; a second adjustable weir extending transversely of the side walls and forming with the first weir, the side walls and the bottom member a first chamber, the first chamber having an aspirating slot therein which is positioned below the interface of the two fluids and is so shaped that upon movement of said body relative to said liquids a suction will be created at the slot causing the heavier liquid to be withdrawn from said first chamber through said slot; a back wall positioned transversely of said side members and forming with said second weir, said bottom member and said side wall a second chamber in which may be collected the lighter of the two liquids which flows over said second weir; said first weir extends downwardly and rearwardly toward the back wall of said apparatus and defines at its trailing end a substantially horizontal portion; and said bottom member has a leading edge which extends over the trailing end of said first weir to define therewith said aspirating slot through which the heavier of the two liquids may be withdrawn upon forward movement of said apparatus.
Claim 3
Dependent Claim
31 words
The apparatus of claim 1 including: a swash plate mounted between said side walls and extending downwardly into said first chamber to minimize turbulence of said liquids in said first chamber.
Claim 4
Dependent Claim
20 words
The apparatus of claim 1 wherein: said side walls have inwardly converging portions between the first and second weir members.
Claim 5
Dependent Claim
30 words
The apparatus of claim 1 including: a wide mesh screen disposed between said wall members forwardly of said first weir to prevent the entry of large objects into said apparatus.
