Patent number: 9150426Abstract: The product of a molten alkali metal metalate phase separation can be processed into a purified metal from a metal source. Metal sources include native ores, recycled metal, metal alloys, impure metal stock, recycle materials, etc. The method uses a molten alkali metal metalate as a process medium or solvent in purifying or extracting high value metal or metal oxides from metal sources. Vitrification methods using the silicate glass separation phase can be prepared as is or can be prepared with a particulate phase distributed throughout the silica glass phase and encapsulated and fixed within the continuous glass phase. Tungsten metal can be obtained from an alkali metal tungstate. A typically finely divided tungsten metal powder can be obtained from a variety of tungsten sources including recycled tungsten scrap, tungsten carbide scrap, low grade tungsten ore typically comprising tungsten oxide or other form of tungsten in a variety of oxidation states.Type: GrantFiled: December 7, 2007Date of Patent: October 6, 2015Assignee: TUNDRA COMPOSITES, LLCInventor: Rodney Kieth Williams

Publication number: 20090236057Abstract: A reduced visibility insect screening is described having a transmittance of at least about 0.75 and a reflectance of about 0.04 or less. In an alternative embodiment, an insect screening material includes screen elements having a diameter of about 0.005 inch (0.13 mm), having a bond strength greater than 5500 psi (40 mega Pascals), and having the same transmittance and reflectance limits. In another embodiment of the invention, a screening includes screen elements having a diameter of about 0.005 inch (0.1 mm) or less and a coating on the screen elements having a matte black finish, where the screening has the same transmittance and reflectance limits.Type: ApplicationFiled: May 26, 2009Publication date: September 24, 2009Inventors: Russell John Pylkki, Patrick Jerome Gronlund, Rodney Kieth Williams, Kurt E. Heikkila
