Abstract
Abstract A recovery device for the removal of a less dense liquid from a more dense one which has particular application for the recovery of oil from bodies of water. The device floats and has a number of improved features over previous similar devices which contribute to improved flow characteristics of the contaminated liquid as it passes through the separation stages. A rotatable collecting head may be driven at a variable speed ratio to the remainder of the separation apparatus to regulate the intake of the contaminated liquid and streamlined construction of the separation apparatus is disclosed having an improved filtering means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A DEVICE FOR SEPARATING TWO LIQUIDS OF DIFFERENT DENSITIES FORMING A LIQUID INTERFACE, INCLUDING: A ROTATABLE CYLINDRICAL MEMBER DISPOSED WITHIN SAID DEVICE, AN INVERTED TROUGH SUPPORTED BY AND DISPOSED IN A SPIRAL FASHION AROUND THE PERIMETER OF SAID CYLINDRICAL MEMBER, A SEPARATION CHAMBER DISPOSED WITHIN SAID ROTATABLE CYLINDRICAL MEMBER, SAID SEPARATION CHAMBER COMMUNICATING WITH THE BASE OF SAID INVERTED TROUGH TO RECEIVE THE LESS DENSE LIQUID, AND ROTATABLE LIQUID COLLECTION MEANS SPANNING SAID LIQUID INTERFACE TO DIRECT SAID LIQUIDS INTO SAID TROUGH, SAID LIQUID COLLECTION MEANS ROTATABLE AT A VARIABLE SPEED RELATIVE TO THE SPEED OF ROTATION OF SAID ROTATABLE CYLINDRICAL MEMBER.
Claim 2
Independent Claim
102 words
A DEVICE FOR SEPARATING TWO LIQUIDS OF DIFFERENT DENSITIES FORMING A LIQUID INTERFACE, INCLUDING: A ROTATABLE CYLINDRICAL MEMBER DISPOSED WITHIN SAID DEVICE, AN INVERTED TROUGH SUPPORTED BY AND DISPOSED IN A SPIRAL FASHION AROUND THE PERIMETER OF SAID CYLINDRICAL MEMBER, A SEPARATION CHAMBER DISPOSED WITHIN SAID ROTATABLE CYLINDRICAL MEMBER, SAID SEPARATION CHAMBER COMMUNICATING WITH THE BASE OF SAID INVERTED TROUGH TO RECEIVE THE LESS DENSE LIQUID, AND ROTATABLE LIQUID COLLECTION MEANS SPANNING SAID LIQUID INTERFACE TO DIRECT SAID LIQUIDS INTO SAID TROUGH, SAID LIQUID COLLECTION MEANS ROTATABLE AT A VARIABLE SPEED RELATIVE TO THE SPEED OF ROTATION OF SAID ROTATABLE CYLINDRICAL MEMBER.
Claim 3
Dependent Claim
27 words
The device of claim 1 wherein said collection means is rotated by means of a gear assembly independent of a gear assembly rotating said rotatable cylindrical member.
Claim 4
Dependent Claim
27 words
The device of claim 1 wherein sidewalls of said inverted trough intersect to form a vertex spaced away from the external surface of said rotatable cylindrical member.
Claim 5
Dependent Claim
15 words
The apparatus of claim 1 including means to heat the liquids within said inverted trough.
Claim 6
Dependent Claim
24 words
The device of claim 1 including means disposed in heat exchange relationship with said inverted trough for heating said liquid flowing in said trough.
Claim 7
Dependent Claim
46 words
The device of claim 1 wherein said inverted trough includes water ejection means disposed at spaced intervals at the periphery of said trough for ejecting water toward the vertex of said trough, said water ejection means communicatinG with spiral-shaped fluid conduit means supported by said trough.
Claim 8
Dependent Claim
39 words
The device of claim 1 wherein said separation chamber includes an inverted funnel-shaped member to receive the less dense liquid, and liquid conduit means cooperatively associated with said funnel-shaped member for removing said less dense liquid from said chamber.
Claim 9
Dependent Claim
25 words
The device of claim 7 wherein said separation chamber includes a stationary spiral member for directing said less dense liquid into said inverted funnel-shaped member.
Claim 10
Dependent Claim
22 words
The device of claim 7 wherein said separation chamber includes filtering means to prevent debris from passing to said liquid conduit means.
