Patent number: 7967982Abstract: A skimming system for removing a floating layer from a water surface. The skimming system includes at least one guide element that is movable relative to the floating layer, which guide element includes at least one unit that catches the floating layer. The at least one removal unit includes at least one collecting container that is detachably attached to the guide element. The collecting container is furthermore vertically adjustable, so that it is not only easy to detach and exchange the collecting container but that it is moreover possible to position the floating layer removal means at a desired depth in or below the floating layer. In this way an optimum removal of the floating layer can be realized. The inlet of the collecting container is present at a location where the extent to which water is mixed with the floating layer is minimal.Type: GrantFiled: August 10, 2006Date of Patent: June 28, 2011Assignee: Koseq B.V.Inventor: Gerrit Kampers

Patent number: 7104407Abstract: An apparatus for separating a first fluid from a mixture of fluids in a container, the first fluid being substantially immiscible with respect to one or more other fluids in the mixture comprises an endless strip of material having an affinity for the first fluid, a pair of members for advancing successive portions of the strip into and out of contact with the first fluid and a means for maintaining the successive portions of the strip in contact with the first fluid as the successive portions of the strip are sequentially advanced. The pair of members have cooperating surfaces that positively engage the strip with sufficient force so that movement of the members relative to one another sequentially advances successive portions of the strip. The apparatus can comprise a tube skimmer that is employed to separate tramp oil from a coolant in a machining operation.Type: GrantFiled: September 17, 2004Date of Patent: September 12, 2006Assignee: Zebra Skimmers Corp.Inventors: Steven Davidian, Christopher Fenn

Patent number: 6962659Abstract: An oil skimmer for removing oil floating on surfaces of bodies of water. The oil skimmer includes a support frame, respective drive pulley and guide pulleys rotatably mounted to the support frame on respective shafts, and a drive train which rotatively drives the drive pulley and guide pulleys. A skimmer hose in the form of a loop to which oil adhere floats on the body of water and is driven by the drive pulley through the guide pulley onto and off the surface of the body of water carrying adhered oil. A skimmer hose scraper disposed between the drive and guide pulleys removes the oil from the skimmer hose into a collection receptacle. The drive and guide pulleys comprise replaceable, quick changing inner and outer pulley halves that sandwich respective central hubs therebetween to space the pulley halves to fit skimmer hoses of different cross-sectional sizes. The central hubs with attached drive and guide pulley halves are affixed to the drive shafts using a quick release nut which threads to the shafts.Type: GrantFiled: February 21, 2003Date of Patent: November 8, 2005Assignee: Skimtech, Inc.Inventors: Blake W. Rhein, Frances L. Deley, Jr.

Patent number: 6905597Abstract: A device for recovering oil from an oil-slick on a stretch of water is supported on the water by at least one first floating body and is provided with an inlet that is open facing the oil-slick and that flows into a channel with side walls. The channel is provided with at least one separating body that extends between the side walls in such a manner that an upper drain zone is formed above the separating body and a separate lower drain zone is formed below the separating body. The front edge of the separating body facing the oil-slick is substantially disposed on the level of the water/oil interface and the oil can be discharged from the upper drain zone. The device makes use of the natural interface between the oil-slick and the subjacent water.Type: GrantFiled: May 23, 2001Date of Patent: June 14, 2005Inventors: Helga Garbaty, Stefan Garbaty, Thomas Garbaty, Harriet Garbaty, Rudolf Franz Garbaty

Patent number: 6887387Abstract: A skimmer for removing oil and paramagnetic chips from a contaminated body of machine tool coolant. The skimmer includes a frame and an endless tube partially trained within the frame that defines a travel path. The path of the tube includes a first section within the body of coolant and a second section out of the body of coolant. The skimmer further includes a magnet disposed within the tube, a drive system mounted to the frame and operatively coupled to the tube to power travel of the tube, and a wiper connected to the frame at a position along the travel path. The wiper is advantageously positioned adjacent to the tube such that the wiper removes oil and metal chips carried by the tube. A receptacle is includes that delineates a collection space positioned below the wiper to receive oil and metal chips.Type: GrantFiled: August 25, 2003Date of Patent: May 3, 2005Assignee: Abanaki CorporationInventor: Mark T. Hobson

Patent number: 6881335Abstract: An apparatus or system for containing oil and the like floating on the surface of a body of water, comprising a relatively elongate channel defined by two side-defining faces that diverge from one another from a narrow inner end to a wider opening, the channel being movable such as by towing with the aid of one or more vessels, which apparatus is made of non-rigid materials. The apparatus comprises a tapered channel portion between the two side-defining faces, a wedge-shaped structure and a collecting means or separator, wherein the tapered channel portion, the wedge-shaped structure and the separator are arranged one after the other as interconnected or integrated units, thereby forming a continuous “hull” having freeboard, and longitudinal towing devices are provided that are fastened to said units, the said towing devices and thus the towing forces intersecting in an area at the rear end of said wedge-shaped structure seen in the towing direction.Type: GrantFiled: July 26, 2001Date of Patent: April 19, 2005Assignee: Nofi Tromso ASInventor: Dag Nilsen
