Abstract: A continuous oil containment boom foldable to a compact configuration for storage in standard size 8' by 8' by 20' shipping containers, arranged for quick deployment. The containment boom comprising a plurality of boom segments having a lower floatation member and an upper impermeable barrier that is inclined to extend over the layer of contaminants to further serve as a thermal shield barrier to lower the temperature in the area adjacent to the upper barrier. The boom segments being joined end-to-end by pivot joints having vertically oriented overlapping plates that are pivotally connected by a pivot hinge for relative pivotal movement about a horizontally axis, the pivot joints further having a pair of vertically oriented hinge assemblies for relative pivotal movement about a vertical axis.

Abstract: Apparatus is disclosed for converting ocean wave motion to useable electrical energy. A float is mounted to a raft in a manner to permit movement of the float, relative to the raft, in response to ocean wave motion. An upward drive mechanism is responsive to upward motion of the float to rotate a shaft in a predetermined direction. A downward drive mechanism is responsive to downward motion of the float to rotate the shaft in the same predetermined direction. A conventional electrical generator is coupled to the shaft for converting the rotation of the shaft to electrical energy. In another embodiment the float is adapted to be dropped from an initial position above the surface of a body of water toward the water. A motor cooperates with a control assembly to lift the float from a pickup position to its initial position such that the float may again fall.
