20080072707 - Methods and apparatus for spray forming, atomization and heat transfer: The present invention is directed to methods and apparatus that use electrostatic and/or electromagnetic fields to enhance the process of spray forming preforms or powders. The present invention also describes methods and apparatus for atomization and heat transfer with non-equilibrium plasmas. The present invention is also directed to articles, particularly... Agent: Wilmerhale/dc

20080066577 - Precious metal recovery using thiocyanate lixiviant: A heap with precious metal-containing mineral material with precious metal locked within sulfide mineralization is subjected to bio-oxidation followed by acidic thiocyanate leaching to dissolve precious metal. Sulfide sulfur is oxidized during both of the bio-oxidation and the thiocyanate leaching.... Agent: Marsh, Fischmann & Breyfogle LLP

20080066578 - Precious metal recovery using thiocyanate lixiviant: For removal of precious metal from thiocyanate leach solution, precious metal is transferred from precious metal-thiocyanate complex to precious metal-cyanide complex. Preparation of thiocyanate leach solution includes dissolving cyanide in an aqueous liquid and converting the cyanide to dissolved thiocyanate.... Agent: Marsh, Fischmann & Breyfogle LLP

20080066579 - Treatment of steel plant sludges in a multiple-stage furnace: The invention concerns a method for treating iron-and-steel plant sludge comprising adjusting the available CaO content of the sludge so as to obtain an available CaO content of 3% to 8% based on the sludge weight, adding a carbon-containing fuel, introducing the sludge onto one of the upperstages of a... Agent: Nath & Associates

20080060477 - Method of preparingiron-based components: The present invention concerns a process for the preparation of high density green compacts comprising the steps of providing an iron-based powder essentially free from fine particles; optionally mixing said powder with graphite and other additives; uniaxially compacting the powder in a die at a compaction pressure of at least... Agent: Buchanan, Ingersoll & Rooney PC

20080053273 - Method for producing raw material powder for rare earth sintered magnet, method for producing rare earth sintered magnet, granule and sintered body: A method for producing a rare earth sintered magnet uses granules having an excellent fluidity to improve the dimensional accuracy and production of a compact formed of the granules without significant property losses. The granules are formed by adding an organic liquid to primary alloy particles having a predetermined composition... Agent: Pearne & Gordon LLP

20080053274 - Glass stability, glass forming ability, and microstructural refinement: The present invention relates to the addition of niobium to iron based glass forming alloys. More particularly, the present invention is related to changing the nature of crystallization resulting in glass formation that may remain stable at much higher temperatures, increasing the glass forming ability and increasing devitrified hardness of... Agent: Grossman, Tucker, Perreault & Pfleger, PLLC

20080053276 - Process for enhanced acid leaching of laterite ores: A process is described for the recovery of nickel and cobalt from a nickeliferous laterite ore including the steps of: providing a nickeliferous laterite ore and separating that ore into its low magnesium limonite fraction and high magnesium saprolite fraction; treating the limonite fraction in acid solution in a primary...
