Patent number: 8675806Abstract: Example embodiments relate to a method and apparatus for reducing electrostatic deposition of charged particles on wetted surfaces that are exposed, periodically or substantially continuously, to high velocity fluid flow within a coolant flow path in a nuclear reactor. The method may include depositing a first or base dielectric layer and a second or outer dielectric layer on a conductive surface that forms a portion of a high velocity flow path to attain the apparatus. The first dielectric layer material is selected to provide improved adhesion and insulation to the conductive surface and the second dielectric layer material is selected to provide suitable adhesion to the first dielectric layer and improved corrosion and/or mechanical resistance in the anticipated operating environment.Type: GrantFiled: September 16, 2011Date of Patent: March 18, 2014Assignee: General Electric CompanyInventors: Catherine Procik Dulka, Young Jin Kim, Rajasingh Schwartz Israel, David Wesley Sandusky, Kevin H. Janora, Peter W. Brown, Tianji Zhao

Publication number: 20090256460Abstract: A lamp and method for the reduction of gas loss in a high temperature lamp includes providing a light source and a surrounding shroud, using a fill gas outside of the light source and inside the shroud having a thermal conductance greater than nitrogen, and modifying the shroud so that it contains at least 20% of the initial fill gas for at least the rated life of lamp operation. The shroud is preferably modified by one or more of selecting the shroud material, controlling the thickness of the shroud, providing a coating on the shroud, and the selection of the fill gas.Type: ApplicationFiled: April 14, 2008Publication date: October 15, 2009Inventors: Gary Robert Allen, Rajasingh Schwartz Israel, Elizabeth Anne Guzowski, Rocco Thomas Giordano, Peter W. Brown, Deeder Aurongzeb

Patent number: 6773141Abstract: A reflector lamp has a generally parabolic shaped housing (12) with an interior surface coated with a layer (14) of silver having a protective layer (16) of a stable protective oxide, such as silica, disposed thereon. An intermediate layer (18), such as a layer of elemental silicon, protects the silver layer during deposition of the silica layer and is completely or substantially consumed during formation of the silica layer. The lamp includes a light source (48) having a longitudinal axis (x) disposed on the parabolic reflector axis and preferably disposed outward of the parabolic focus (F). During lamp fabrication, the protective coating is preferably annealed to improve reflectance. The preferred lamp will have a lumens per watt greater than 14.Type: GrantFiled: March 14, 2002Date of Patent: August 10, 2004Assignee: General Electric CompanyInventors: Tianji Zhao, Rajasingh Schwartz Israel, Frederick Walter Dynys, Thomas Gene Parham
