Abstract
Abstract In a method of collecting light-weight substance floating on a liquid the light-weight substance is sprayed with the aid of a liquid jet into an accumulator tank in that the light-weight substance lands together with the liquid jet as a downward stream about a lower edge of the open bottom of the tank into said tank. In order to keep the liquid jet effective the disintegration of the liquid jet is prevented. To this end the liquid jet is guided above the layer of light-weight substance along a bar or similar guide means.

The method of collecting oil floating on a body of water, comprising the steps of: (a) providing an enclosure with an open bottom and side walls extending from a depth below the interface between the oil and water to above the surface of the oil floating on the body of water; (b) locating a nozzle above a free surface of said oil on the body of water outside of and spaced from said side walls and downwardly inclined for directing water from said nozzle freely against said free surface to a location beneath the open bottom of said enclosure; (c) locating a guide member in downwardly inclined position to extend from above said free surface but below said nozzle, to a point below said free surface and in alignment with said nozzle; and (d) directing a stream of water only from said nozzle to flow therefrom while concentrically surrounding and clinging to said guide member and with such force as to displace oil at said free surface to a location beneath said open bottom of the enclosure.
