| 20110024233 | MAINTENANCE PLATFORM FOR WIND TURBINES - There is provided a suspendable maintenance platform for accessing a blade of a wind turbine. The platform includes arms for holding a maintenance unit, a frame onto which each arm is movably attached in a joint enabling planar movement, and means for supporting the frame in relation to the wind turbine tower. The maintenance unit is slidably attached to the arms that are configured for positioning the platform in relation to the blade, and wherein the frame is configured to be in close proximity to the turbine tower. | 02-03-2011 |

| 20090123772 | HYDROPHILIC COATING METHOD FOR MEDICAL DEVICES - A hydrophilic coating is applied to the surface of a substrate by a method which comprises the steps of (a) applying a first coating comprising a polyvinyl chloride copolymer; and (b) applying a second coating comprising a mixture of a poly(N-vinyl lactam), a polyvinyl chloride copolymer and optionally a zwitterionic compound. Preferably the polyvinyl chloride copolymer is a vinyl chloride-vinyl acetate copolymer. A substrate resulting from the method and a kit for carrying out the method are also provided. | 05-14-2009 |

| 20100247931 | TREATING SURFACES TO ENHANCE BIO-COMPATIBILITY - Described is a method of treating an article having at its surface oxide or hydroxide moieties, as well as the resulting treated article. The method includes priming the surface of the article by contact with an alkoxysilane in an aprotic organic solvent in the presence of an acid catalyst so that the alkoxysilane reacts with the oxide or hydroxide moieties of the surface. This yields a primed surface. A polymer is then reacted with one or more amino, hydroxyl, carboxylic acid and/or acid anhydride groups on the surface to covalently couple the polymer to the primed surface via the alkoxysilane. The reaction with the polymer is not a free-radical reaction. | 09-30-2010 |

| 20090107881 | METHODS FOR INCREASING CATALYST CONCENTRATION IN HEAVY OIL AND/OR COAL RESID HYDROCRACKER - Methods and systems for hydrocracking a heavy oil feedstock using, a colloidally or molecularly dispersed catalyst (e.g., molybdenum sulfide) which provide for concentration of the colloidally dispersed catalyst within the lower quality materials requiring additional hydrocracking. In addition to increased catalyst concentration, the inventive systems and methods provide increased reactor throughput, increased reaction rate, and of course higher conversion of asphaltenes and lower quality materials. Increased conversion levels of asphaltenes and lower quality materials also reduces equipment fouling, enables the reactor to process a wider range of lower quality feedstocks, and can lead to more efficient use of a supported catalyst if used in combination with the colloidal or molecular catalyst. | 04-30-2009 |

| 20090310435 | MIXING SYSTEMS FOR INTRODUCING A CATALYST PRECURSOR INTO A HEAVY OIL FEEDSTOCK - Systems for mixing a catalyst precursor with a heavy oil feedstock preparatory to hydroprocessing the heavy oil feedstock in a reactor to form an upgraded feedstock. Achieving very good dispersion of the catalyst precursor facilitates and maximizes the advantages of the colloidal or molecular hydroprocessing catalyst. A catalyst precursor and a heavy oil feedstock having a viscosity greater than the viscosity of the catalyst precursor are provided. The catalyst precursor is pre-mixed with a hydrocarbon oil diluent, forming a diluted catalyst precursor. The diluted precursor is then mixed with at least a portion of the heavy oil feedstock so as to form a catalyst precursor-heavy oil feedstock mixture. Finally, the catalyst precursor-heavy oil feedstock mixture is mixed with any remainder of the heavy oil feedstock, resulting in the catalyst precursor being homogeneously dispersed on a colloidal and/or molecular level within the heavy oil feedstock. | 12-17-2009 |
| 20100294701 | METHODS FOR HYDROCRACKING A HEAVY OIL FEEDSTOCK USING AN IN SITU COLLOIDAL OR MOLECULAR CATALYST AND RECYCLING THE COLLOIDAL OR MOLECULAR CATALYST - A hydrocracking system involves introducing a heavy oil feedstock and a colloidal or molecular catalyst, or a precursor composition capable of forming the colloidal or molecular catalyst, into a hydrocracking reactor. The colloidal or molecular catalyst is formed in situ within the heavy oil feedstock by intimately mixing a catalyst precursor composition into a heavy oil feedstock and raising the temperature of the feedstock to above the decomposition temperature of the precursor composition to form the colloidal or molecular catalyst. The colloidal or molecular catalyst catalyzes upgrading reactions between the heavy oil feedstock and hydrogen and eliminates or reduces formation of coke precursors and sediment. At least a portion of a resid fraction containing residual colloidal or molecular catalyst is recycled back into the hydrocracking reactor to further upgrade the recycled resid fraction portion and provide recycled colloidal or molecular catalyst within the hydrocracking reactor. | 11-25-2010 |

| 20110065969 | METHOD AND SYSTEM FOR OXIDATIVELY INCREASING CETANE NUMBER OF HYDROCARBON FUEL - High energy (e.g., ultrasonic) mixing of a liquid hydrocarbon feedstock and reactants comprised of an oxidation source, catalyst and acid yields a diesel fuel product or additive having substantially increased cetane number. Ultrasonic mixing creates cavitation, which involves the formation and violent collapse of micron-sized bubbles, which greatly increases the reactivity of the reactants. This, in turn, substantially increases the cetane number compared to reactions carried out using conventional mixing processes, such as simple mechanical stirring. Alternatively, an aqueous mixture comprising water and acid can be pretreated with an oxidation source such as ozone and subjected to ultrasonic cavitation prior to reacting the pretreated mixture with a liquid hydrocarbon feedstock. | 03-17-2011 |
