20080295988 | METHOD FOR REMOVAL OF CORES FROM NIOBIUM-BASED PART, AND RELATED CASTING PROCESS - A method of removing an yttria-based core from a niobium-based part is described. In the method, the core is treated with an effective amount of a leaching composition. The leaching composition is based on nitric acid, or a combination of nitric acid and phosphoric acid. The core material is effectively removed from the niobium-based part, and the process of removing the core does not detrimentally affect the quality of the part. Related casting techniques for various niobium-based parts are also described. | 12-04-2008 |
20090275463 | METHOD OF MAKING A CATALYST WASHCOAT - A method for making a catalyst includes providing a sol that sol includes a catalyst and a catalyst substrate; drying the sol via freeze-drying, spray drying, freeze granulation, or supercritical fluid drying to form a powder; mixing the powder with a solvent to form a slurry; and washcoating the slurry onto a catalyst support. Another method for making a catalyst includes providing a sol, wherein the sol includes a catalyst substrate; drying the sol via freeze-drying, spray drying, freeze granulation, or supercritical fluid drying to form a powder; mixing the powder with a solvent to form a slurry; washcoating the slurry onto a catalyst support; and depositing a catalyst onto the catalyst substrate. | 11-05-2009 |

20110166015 | PROCESS FOR PREPARING CATALYST POWDER - The present invention details a process for producing a catalyst powder. The steps of the process include preparing catalyst slurry, drying, pyrolyzing, and calcining the catalyst slurry to obtain a calcined catalyst powder. The catalyst slurry comprises a catalyst, a liquid carrier, a templating agent, and a catalyst substrate. The catalyst slurry is dried to obtain a raw catalyst powder. The raw catalyst powder is heated in a first controlled atmosphere to obtain a pyrolyzed catalyst powder and the pyrolyzed catalyst powder is calcined in a second controlled atmosphere to obtain a calcined catalyst powder. A method of fabricating a catalyst surface and catalytic converter using the prepared catalyst powder is also illustrated. | 07-07-2011 |

20140327023 | PHOSPHOR ASSEMBLY FOR LIGHT EMITTING DEVICES - A method for fabricating a light emitting device is disclosed. The light emitting device includes a light emitting diode (LED). The method includes disposing a layered phosphor composite or a thick phosphor composite radiationally coupled to the LED to form a light emitting device. The layered phosphor composite includes a first phosphor layer including a yellow-emitting phosphor over a second phosphor layer including manganese-doped potassium fluorosilicate (PFS). The second phosphor layer is disposed closer to the LED. The mass of the PFS of this light emitting device is at least 15% less than mass of the PFS in a reference light emitting device that has the same color temperature as the above mentioned light emitting device, but includes a blend of PFS and the yellow emitting phosphor instead of a layered configuration or has a decreased thickness. | 11-06-2014 |
