Patent number: 8101069Abstract: An External Filtering and Absorbing Device for Use in a Local Containment Area contains filter material with a mesh size not less than 50 microns for removing contaminants from ballast or bilge water from a ship or effluent from a storm drain. Examples of contaminants removed are aquatic nonindigenous species such as Fish, Zebra and Quagga Mussels, Asiatic Clam, Aquatic Weeds, Green Crabs, or other suspended particle contaminants. Filtering is accomplished above the ambient water allowing easy visual verification and visual gratification of the efficacy of the filter unlike closed on-board systems. Water and oil permeate the filter and flow into a local containment area where oil is absorbed by absorbent pads held in pockets. The filter is easily removed and can be sent to authorities to demonstrate compliance with environmental standards. Water sampling containers or instruments used with the assembly allow for further compliance monitoring.Type: GrantFiled: November 10, 2009Date of Patent: January 24, 2012Inventor: Sky Bleu Martin

Publication number: 20110297619Abstract: The present embodiments disclose apparatuses and methods for extracting oil and other hydrocarbons from bodies of water (and, in some embodiments, from solid ground), using, for example, polyester (typically polyethylene terephthalate fibers coated in latex) and/or nylon tire reinforcement cords contained within water-permeable containment devices.Type: ApplicationFiled: June 8, 2011Publication date: December 8, 2011Inventor: Stephen C. Kurtzman

Publication number: 20110284450Abstract: Quilted absorbent pad panel of cluster or ball fiber that contains: Polyester ball or cluster (spherical) fiber; Cotton/Polyester Water and Oil Permeable Fabrics; and attachment means. The fiber is laid out in a “wave”. Next, the “wave” of ball or cluster fiber must be placed and retained between two layers of cotton/polyester water/oil permeable fabric. To retain the fiber between the two layers of cotton/polyester water/oil permeable fabric a unique quilt is created. Unique quilting creates defined closed compartments in which the fiber and cotton polyester fabrics are affixed. Absorbent pad panels are used to absorb and remove oil from the surface of water. Siliconized polyester ball fibers are locked into the sewn compartments of the absorbent pad panels and passively draw the oil from the surface of the water and at the same time repel water so only oil is absorbed in an uncontaminated state.Type: ApplicationFiled: October 15, 2010Publication date: November 24, 2011Inventors: Daniel O'Blair Chadwick, Kenneth Richard Lieblein

Publication number: 20110272361Abstract: Strong fabrics with an affinity for oil can be deployed from boats and other sea vessels to absorb oil that has been spilled into oceans, gulfs, rivers, or other bodies of water. For example, strong nylon spunbonded fabrics can be used to soak up oil from bodies of water. The fabrics can also be used in concert with other methods, such as with containment booms.Type: ApplicationFiled: May 26, 2010Publication date: November 10, 2011Inventors: Albert E. Ortega, James T. Walker, William Warren Whitfield, Jim Bostwick

Patent number: 8034236Abstract: A floatable skimmer apparatus is movably attached in a storm water filter box with a pair of tracks attached in the housing chamber of the filter box. A floatable skimmer has a skimmer panel having floatation members attached to the inlet side of the storm water filter box for raising and lowering the skimmer panel responsive to the rise and fall of storm water in the housing chamber. Storm water is forced under the bottom of the floatable skimmer panel while blocking floatable debris from entering the housing chamber outlet. A floatable hydrocarbon absorbing boom is attached to the skimmer panel and floated independent thereof.Type: GrantFiled: May 6, 2009Date of Patent: October 11, 2011Inventor: Thomas H. Happel

Patent number: 7914683Abstract: Hydrogen generator coupled to or integrated with a fuel cell for portable power applications. Hydrogen is produced via thermocatalytic decomposition (cracking, pyrolysis) of hydrocarbon fuels in oxidant-free environment. The apparatus can utilize a variety of hydrocarbon fuels, including natural gas, propane, gasoline, kerosene, diesel fuel, crude oil (including sulfurous fuels). The hydrogen-rich gas produced is free of carbon oxides or other reactive impurities, so it could be directly fed to any type of a fuel cell. The catalysts for hydrogen production in the apparatus are carbon-based or metal-based materials and doped, if necessary, with a sulfur-capturing agent. Additionally disclosed are two novel processes for the production of two types of carbon filaments, and a novel filamentous carbon product.Type: GrantFiled: December 4, 2009Date of Patent: March 29, 2011Assignee: University of Central Florida Research Foundation, Inc.Inventor: Nazim Muradov

Patent number: 7785035Abstract: The invention relates to an apparatus (20), a system and a method for collecting material from a water system, and the use of the apparatus (20) as an oil-combating device or rescue device. The apparatus (20) can be arranged to float and be moveable on the water surface (1). The apparatus comprises a cargo space (2) for storing the collected material, a collecting platform (12) connected to the cargo space, over which platform the water of the water system and/or material to be collected from it is arranged to pass before passing into the cargo space, water exhaustion means (5) for removing water from the cargo space, means (11) for adjusting the height of the collecting platform as desired in relation to the level of the water surface of the water system, at least one ballast tank (3) to control the draught of the cargo space as desired and/or means (7) for controlling the effect of the water exhaustion means.Type: GrantFiled: July 17, 2006Date of Patent: August 31, 2010Assignee: Oy-Kappelinranta-Kapelstrand ABInventor: Markku Jarvinen

Patent number: 7780850Abstract: A fluid pollution prevention system is provided for preventing the discharge of petrochemicals from a bilge of a marine vessel. The system may include either or both a locator and an absorber for isolating and/or absorbing hazardous waste from a fluid in the bilge. In one embodiment, the locator is a continuous sidewall or barrier that defines a vertically enclosed fluid volume that is isolated from petrochemicals floating on the surface of fluid in a bilge. The absorber forms a closed geometric shape having an interior area that is disposable about the sidewall and movable along the sidewall as a function of fluid height. The absorber functions to absorb petrochemicals from the fluid and isolate an inlet of the bilge pump from receipt of the same. The absorber may be opened and closed to facilitate placement about the sidewall or other objects.Type: GrantFiled: October 20, 2006Date of Patent: August 24, 2010Inventor: Paul Arthur Clukies
