Abstract
Abstract Apparatus for collecting oil at its source of leakage from a container underwater which includes an elongated, flexible and impervious conduit having an inverted channel-shaped mouth composed of cushioned sealing material and flexible magnet means for mating engagement with the surface of the oil container surrounding the sides and upper portion of the source of leakage for entrapping the oil and elevated conveying means at the opposed end of the conduit for directing the entrapped oil to a collector. The bottom portion of the mouth remains open to permit entry of water into the conduit to float the entrapped oil and accelerate its passage upwardly through the conduit.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
Apparatus for collecting underwater leakage oil from a source of leakage defined by an underwater break in a container which comprises: a flexible, elongated, impervious conduit having an inverted channel-shaped open mouth, flexible magnet means supported by said conduit and bordering said mouth, the said magnet means being adapted for mating engagement with the surface of the container surrounding the sides and upper portion of the source of leakage for entrapping the oil and the water entering the conduit below its mouth, the opposed end of said conduit being elevated above the mouth of the conduit, and conveying means at said opposed conduit end for directing the entrapped oil and water to a collector.
Claim 2
Dependent Claim
