Abstract:
A recovery device for containing a material floating on the surface of a liquid, the device comprising:a shroud having a top and a bottom and ribs, the top being of smaller diameter than the bottom, the top comprising an open top and the bottom comprising an open bottom, the open top having an open area which is smaller than the open area of the open bottom; the device being of sufficient weight so that deployment of the device bottom-first into the liquid causes the device to sink in the liquid to a collection position in which the open bottom is submerged below, and the open top is at or above, the surface of the liquid; whereby positioning the device with the open bottom at the surface of the liquid and over at least a portion of the floating material, and then deploying the device bottom-first into the liquid to encircle with the shroud at least a portion of the floating material and submerging the device to its collection position, forces the floating material encircled by the open bottom into the smaller area of the open top, thereby facilitating collection of the floating material.
