Abstract: 1,239,127. Removing oil from open water. STANDARD OIL CO. 24 Jan., 1969 [29 Jan., 1968], No. 4227/69. Heading B1D. [Also in Division F1] Oil is removed from open water by a layer of foam rubber or polyurethane 22 on drum 15, which rotates to move the layer under rollers 25, 30, so that first the surplus water, then the oil is squeezed out, the oil running from higher compression zone 30a on to roller 25 from which it is wiped by blade 36. The assembly is mounted on a barge or catamaran and thereby moved across the oil slick, drum 15 and the rollers being rotated by a motor. The layer 22 is immersed in the water so that hydrostatic forces assist the oleophilic and hydrophobic properties of the layer to force oil to adhere thereto.
