Publication number: 20070141269Abstract: A coating and method for overcoating a TBC on a component used in a high-temperature environment, such as the combustor section of an industrial gas turbine. The coating defines the outermost surface of the component and is formed of at least two layers having different compositions. An inner layer of the coating contains alumina in a first silica-containing matrix material that is free of zinc titanate. An outer layer of the coating contains alumina, a glass material, and zinc titanate in a second silica-containing matrix material. The outer layer of the coating has a surface roughness of not greater than three micrometers Ra and forms the outermost surface of the component. The coating reduces the component temperature by reducing the convective and radiant heat transfer thereto.Type: ApplicationFiled: January 26, 2007Publication date: June 21, 2007Applicant: General Electric CompanyInventors: Wiliam Stowell, Daniel Ivkovich, Timothy Manning, Tara McGovern, Jane Murphy, Thomas Rentz, Mathew Roling, Raymond Rowe, Andrew Skoog

Publication number: 20070099013Abstract: A method for manufacturing a machine component is provided. The method includes forming a machine component substrate wherein the substrate has a substrate surface region. The method further includes forming at least one primary thermal barrier layer including a first ceramic thermal barrier material having a first porosity. The method also includes forming at least one secondary thermal barrier layer formed over at least a portion of the plurality of primary thermal barrier layers. Also, the secondary thermal barrier layer further includes a second ceramic thermal barrier material having a second porosity that is greater than the first porosity. The method also includes forming at least one tertiary thermal barrier layer comprising a smooth coat material, wherein the tertiary thermal barrier layer is formed over at least a portion of the secondary thermal barrier layer. The secondary thermal barrier layer facilitates reducing a delamination of the tertiary thermal barrier layer.Type: ApplicationFiled: October 27, 2005Publication date: May 3, 2007Inventors: Raymond Rowe, Robert Shalvoy, Warren Nelson

Publication number: 20060160389Abstract: A method for metallurgically bonding a stator bar to a coupling to reduce the incidence of leak paths resulting from corrosion. The stator bar comprises strands through which a liquid coolant can flow. Adjacent ends of the strands are received in an interior cavity of the coupling through an opening in the coupling. A joining material is provided on a first portion of the stator bar within the coupling opening and adjacent the ends of the strands. The first portion is heated to melt the joining material. At essentially the same time, a second portion of the stator bar outside the coupling is also heated. Once the joining material is suitably molten, the first portion is allowed to cool while the second portion remains heated, thereby causing the joining material nearest the ends of the strands to solidify first.Type: ApplicationFiled: February 9, 2006Publication date: July 20, 2006Applicant: GENERAL ELECTRIC COMPANYInventors: Raymond Rowe, Alan Iversen

Publication number: 20060080828Abstract: A method includes blasting the interior surfaces of the fitting to stator bar strand joint with CO2 pellets to remove loose copper oxide which otherwise would interfere with proper sealing between an epoxy and the copper surfaces of the joint. After cleaning the surfaces and applying air under pressure to remove particulate material, epoxy is applied to the brazed joints followed by an evacuation of the fitting to strand joint. Subsequent release of the vacuum ensures that the epoxy fills in all crevices or cracks at the joint surfaces and minimizes or eliminates any tendency of the epoxy to delaminate.Type: ApplicationFiled: October 18, 2004Publication date: April 20, 2006Applicant: General Electric CompanyInventor: Raymond Rowe

Patent number: 4520273Abstract: The rotor generator includes an elongated generally cylindrically shaped mework. An elongated rotor is longitudinally aligned within the framework and is rotatably mounted therein. The rotor has a plurality of curved blades which are capable of causing rotation of the rotor when there is fluid flow, such as water or air current. The rotor has a magnetic characteristic which may be provided by attaching magnets to the rotor blades or magnetizing the blades themselves. A plurality of wires are mounted on the framework about the rotor so that when the rotor is rotated electrical current is induced in the wires. Apparatus is provided for collecting the induced electrical current so that the electrical current can be provided for power purposes, such as charging a battery. With this arrangement the rotor generator can be placed on the bottom of the ocean where there is current flow, and utilized for charging a battery which may in turn power oceanographic equipment.Type: GrantFiled: September 19, 1983Date of Patent: May 28, 1985Assignee: The United States of America as represented by the Secretary of the NavyInventor: Raymond A.

Patent number: 4492875Abstract: The wave powered buoy generator includes a hollow buoy which has inner and uter surfaces. The buoy is preferably spherical in shape. One or more windings are mounted to the buoy parallel to its surfaces with each winding having a pair of ends. A magnetized device which, is preferably a ball, is located within the buoy for rolling back and forth therein. A device is connected to the ends of the windings for rectifying current flow therefrom. With this arrangement the buoy can be moored in a body of water, and, when there is water motion, the flux lines of the magnetized roller device cut the one or more windings so as to cause electrical current flow to be provided through the rectifying device.Type: GrantFiled: December 2, 1982Date of Patent: January 8, 1985Assignee: The United States of America as represented by the Secretary of the NavyInventor: Raymond A. Rowe

Patent number: 4235693Abstract: A submersible energy storage apparatus for an electrical power source is vided which includes an electrolysis unit feed water gas collection assembly and a fuel cell. The electrolysis unit feed water gas collection assembly includes a hydrogen container and an oxygen container wherein each container has a gas outlet and is capable of containing feed water as well as hydrogen and oxygen gases respectively. An electrolysis cell is provided which has a hydrogen outlet, an oxygen outlet and a feed water inlet. The hydrogen outlet is located in the hydrogen container, the oxygen outlet is located in the oxygen container, and the feed water inlet is located in one of the containers. Each of the containers has an opening to the submersible environment so as to be pressure responsive thereto. A barrier device is provided in association with the opening in each container for isolating the feed water in the container from water in the submersible environment.Type: GrantFiled: November 9, 1979Date of Patent: November 25, 1980Assignee: The United States of America as represented by the Secretary of the NavyInventors: Raymond A.
