1. A device for removing from the surface of a body of water a liquid immiscible with water and floating at said water surface, comprising:

  • a liquid separator assembly comprising a generally planar array of separate hollow flat rectangular liquid separators each having a chamber bounded at one side by a screen wall;

    hinge means joining the adjacent separators on hinge axes parallel to the plane of the array with the screen walls of all the separators located at the same side of the array;

    float means on said separator assembly for floating the assembly in said body of water with said separator screen walls located at the underside of the assembly at said water surface;

    each separator being adapted to be initially filled with said liquid and having an outlet through which the liquid may be pumped from the separator chamber to create a pressure differential across the separator screen wall for inducing passage of said liquid only from the water surface into the separator chamber; and

    means for sensing and producing an electrical signal representing said pressure differential.
