Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
134 words
Apparatus for removing a liquid hydrocarbon from a body of water comprising: a catamaran type boat having spaced-apart hulls; an endless belt having a relatively smooth surface made of a material including a high molecular weight solid hydrocarbon, to which said liquid adheres; said belt being positioned entirely between the ends of said hulls with the hulls forming a trough leading to the belt; said endless belt angularly disposed with respect to the water surface with an upper end projecting forward of the lower end with respect to the direction of boat travel; means for continuously moving the lower leg of said endless belt downward into said body of water to enable the liquid to be wetted on said surface; means for wiping the surface of the belt to remove the liquid adhered thereto.
