Abstract
A recovery device ( ) for containing a material ( ) floating on the surface of a liquid ( ) comprises a shroud ( ) having an open top and an open bottom, the top being of smaller diameter than the bottom, thus forming a truncated cone-like shape. The open top has an open area which is smaller than the area of the open bottom. The device ( ) is positioned with the open bottom above the surface of the liquid ( ) and encircling at least a portion of the floating material ( ). It is then allowed to sink to its collection position, in which the open bottom is submerged below, and the open top is at or above, the surface of the liquid ( ). As a result, the floating material ( ) is encircled by the open bottom and is forced into the smaller area of the open top as the device ( ) sinks into the water. The recovery device ( ) may include a collar ( ) attached to the open top, a skirt ( ) attached to the open bottom and ballast weights ( ) to aid in sinking the device ( ).
