  • Patent number: 10633814
    Abstract: Two segments according to the invention, which form a brush structure created by brush fibres and plastic rings, are joined together by bolts or screws and sleeves with a water-permeable discoid hub, in such a way that a separate brush structure can be joined to the segments by stud bolts or similar, to the metal ring of which a plastic ring, equipped with brush fibres, is attached for the collection of very heavy oils. For the cleaning of the brush fibres of the segment and the good recovery of the oil being collected, there is a curved metal sheet, preferably on supports, as a continuation of the cleaner, and which forms a casing-like space, preventing the oil flowing off the brushes from returning to the water circulation and improving the collection capacity. The device is suitable, for instance, for the collection of all grades of oil, with continuously changing properties.

When mounted, the skimming assembly presents vertically orientated starboard, port and bow cages that house oil absorbent padding. The cages with the positioned pads are largely porous so that at slow watercraft velocities, the water flows through the pads but the oil is retained within the pads across a substantially horizontal plane. As the pads become oil saturated along this common plane, the vertical cages are adjusted to expose a section of the pad that is not saturated. This process is repeated until the entire pad surface is saturated. The resistance force created by the water against the starboard and port cages during movement is countered by a plurality of tethering cables extending from the structural members attached to the bow of the watercraft to the outer edges of the cages.

  • Publication number: 20120031848
    Abstract: An adjustable and removable skimming assembly is provided for attaching to the bow of a watercraft. When mounted, the skimming assembly presents vertically orientated starboard, port and bow cages that house oil absorbent padding. The cages with the positioned pads are largely porous so that at slow watercraft velocities, the water flows through the pads but the oil is retained within the pads across a substantially horizontal plane. As the pads become oil saturated along this common plane, the vertical cages are adjusted to expose a section of the pad that is not saturated. This process is repeated until the entire pad surface is saturated. The resistance force created by the water against the starboard and port cages during movement is countered by a plurality of tethering cables extending from the structural members attached to the bow of the watercraft to the outer edges of the cages.

  • Patent number: 8110525
    Abstract: A method of preparing oil-absorbing fibers by: a) fully dissolving a dispersant and a deionized water in a reaction vessel, adding a methacrylate monomer and an initiator to a reactor and stirring to form a homogenous solution, transferring the homogenous solution into the reaction vessel, charging nitrogen gas, stirring, raising temperature to 70-80° C., allowing to react for 2-6 hours, raising temperature to 90-100° C., allowing to react for 2-4 hours, collecting a resultant product, washing, drying, and obtaining a white resin; b) drying the white resin, mixing with a swelling agent, and sealing the mixture at room temperature for 48-96 hours to yield a homogenous gel; c) grinding the gel completely, spinning by a plunger spinner, and coagulating with a coagulation bath to yield an as-spun oil-absorbing fiber; and d) drawing the as-spun oil-absorbing fiber with a draw ratio of 2-6 to yield oil-absorbing fibers.

  • Patent number: 8101069
    Abstract: 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.

  • Publication number: 20110284450
    Abstract: 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.

  • Publication number: 20110272361
    Abstract: 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.

  • Patent number: 8034236
    Abstract: 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.

  • Patent number: 7914683
    Abstract: 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.

  • Patent number: 7780850
    Abstract: 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.
