Abstract
Abstract A floatable collection device where contaminated liquid such as water polluted by oil is collected into a central drum by means of an elongated spiralled inverted V-shaped trough which is circumferentially mounted on the drum. The device includes expulsion means by which the contaminated liquid is expelled from the drum to separation apparatus located elsewhere for separation of the oil from the water.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
101 words
A liquid collection device comprising: a rotatable cylindrical member disposed within said collection device, an inverted trough supported by and disposed in a spiral fashion around the perimeter of said cylindrical member, liquid collection mEans rotatably connected to the upper portion of said cylindrical member to direct collected liquid to said inverted trough, and a circular expulsion chamber located at the base of said collection device cooperatively associated with said inverted trough to receive the liquid flowing from said trough and to direct said liquid through a duct communicating with said chamber to containment means located apart from said collection device.
Claim 2
Dependent Claim
101 words
A liquid collection device comprising: a rotatable cylindrical member disposed within said collection device, an inverted trough supported by and disposed in a spiral fashion around the perimeter of said cylindrical member, liquid collection mEans rotatably connected to the upper portion of said cylindrical member to direct collected liquid to said inverted trough, and a circular expulsion chamber located at the base of said collection device cooperatively associated with said inverted trough to receive the liquid flowing from said trough and to direct said liquid through a duct communicating with said chamber to containment means located apart from said collection device.
Claim 3
Dependent Claim
22 words
The liquid collection device of claim 1 wherein said expulsion chamber includes rotatable propeller means for ejecting said liquid through said duct.
Claim 4
Dependent Claim
50 words
The liquid collection device of claim 1 wherein said trough includes water ejection means disposed at spaced intervals at the periphery of said trough for counterrotatably ejecting water toward the vertex of said trough, said water ejection means communicating with a spiral shaped fluid conduit means supported by said trough.
Claim 5
Dependent Claim
35 words
The liquid collection device of claim 1 including a plurality of outwardly curved encircling vanes disposed around said inverted trough, said encircling vanes forming a cage-like structure which confines said liquid within said inverted trough.
Claim 6
Dependent Claim
30 words
The liquid collection device of claim 1 including curved vane means constructed and arranged to permit passage of said liquid but to exclude passage of debris into said collection means.
Claim 7
Dependent Claim
33 words
The liquid collection device of claim 1 including means disposed in heat exchange relationship with said inverted trough for heating said liquid flowing in said trough to increase the fluidity of said liquid.
Claim 8
Dependent Claim
22 words
The liquid collection device of claim 6 in which said heating means comprise spiral fluid conduit means contiguous to said inverted trough.
