Filed:

Sep 26, 1996

Appl. No.:

8/725217

Inventors:

John Wehrle - Greenbelt MD
Eugene C. Fischer - Stevensville MD
William P. Kenney - Annapolis MD
Joseph F. Korczynski - Glen Burnie MD
Thomas D. Gracik - Glen Burnie MD
Barbara F. Howell - Arnold MD

Assignee:

The United States of America as represented by the Secretary of the Navy - Washington DC

International Classification:

B01D 2126
B01D 6316

US Classification:

21032167

Abstract:

Oil spill polluted water is conducted under pressure in sequence through arator devices to collect and burn a polluted water mixture having its oil concentration increased by extraction of water therefrom during axial flow through the separator devices. Such water extraction is effected by sequential radial outflow through oil flow blocking filter walls of the separator devices in response to rotation thereof.

US Classification:

264 401

Abstract:

A method and apparatus for replicating the submerged surfaces of ships and other marine structures. One apparatus includes a housing which is partitioned into forward and rear chambers by a membrane and a piston member, which is carried by the membrane. Upon selective flooding of the rear chamber and evacuation of the forward chamber, the piston member is moved toward the submerged surface to form an evacuated molding region therebetween. Liquid molding material is then drawn into the evacuated molding region and the molding device is retained in position until the material solidifies. An alternative molding apparatus includes a housing with peripheral suction elements for releasably securing the housing to the submerged surface so that a molding region is defined therebetween. Upon displacement of water from and subsequent evacuation of the molding region, settable molding material is introduced into the molding region.
