    Abstract: An electrical assembly for use in various operating environments such as a casing of a combustion turbine 10 is provided. The assembly may include an electrical energy-harvesting device 51 disposed in a component within the casing of the turbine to convert a form of energy present within the casing to electrical energy. The harvesting device is configured to generate sufficient electrical power for powering one or more electrical devices therein without assistance from an external power source. One example of electrical devices wholly powered by the energy harvesting device may be a sensor 50 connected for sensing a condition of the component within the casing during operation of the combustion turbine. Another example of electrical devices wholly powered by the energy harvesting device may be a transmitter in communication with the sensor for wirelessly transmitting the data signal outside the casing.

    Abstract: A ceramic thermal barrier coating material (10) containing nano-sized features is predicted to exhibit improved high temperature performance than a comparable material containing fewer of such features. In a coating deposited by an APS process, the nano-sized features may be intersplat columns (32). In a coating deposited by an EB-PVD process, the nano-sized features may be a mixed oxide layer (22) formed of nano-sized mixed oxide particles, or nano-sized alumina projections (24) extending across the interface from the mixed oxide layer into the insulating material layer (20). Alternatively, the nano-sized features may be secondary columnar grains (36) extending laterally from primary columnar grains (34) in a columnar-grained ceramic material.

    Abstract: A peer-to-peer network propagates searches from client to client. Resources within each client are selectively searched in response to authentication and authorization processes. Authentication information may be included in a search request or may be performed by an authentication process external to the client. Authorization is performed by a process external to the client. Only after authentication or authorization may resources of any particular client be accessed. The system allows for secure propagated searches and resource access in a peer-to-peer network environment. The network may further include a server for maintaining a list of clients connected to the peer-to-peer network in order to more efficiently facilitate peer-to-peer communications.

    Abstract: A method of forming an interstage seal including removing a diaphragm seal box (14) from a gas turbine compressor assembly (10) and removing a labyrinth sealing member (12) from the diaphragm seal box (14). An abradable material layer (34) may be deposited on the diaphragm seal box (14). A spray gun may be mounted in relation to an engine disk (16) of the gas turbine compressor assembly (10) for cold-spraying a quantity of particles toward the engine disk (16). The particles may be sprayed at a velocity sufficiently high to cause at least a portion of the quantity of particles to adhere to the engine disk (16). The spray gun may be controlled to deposit a quantity of particles on the compressor disk (16) to form a geometry (32) that will abrade the abradable material layer (34) during operation of the gas turbine compressor assembly (10). The geometry (32) abrading the abradable material layer (34) forms an interstage seal. Rotation of the engine disk (16) within the gas turbine compressor assembly (10) may be controlled during the step of controlling the spray gun. The diaphragm seal box (14) may be reinstalled within the gas turbine compressor assembly (10) so that the geometry (32) aligns with the abradable material layer (34).

    Abstract: A method of depositing a catalytically reactive coating to a substrate including selecting a target light off temperature for a predetermined catalytic combustion environment, selecting a thermal barrier coating composition, selecting a catalytic material and codepositing the thermal barrier coating composition and the catalytic material onto the substrate in proportions selected to produce the target light off temperature when exposed to the combustion environment. The method may include controlling the codepositing step to cause the thermal barrier coating composition to interact with the catalytic material to produce a phase having a light off temperature different from the respective light off temperatures of the thermal barrier coating composition and the catalytic material. A catalyst element may include a substrate and a first layer comprising a thermal barrier coating composition and a catalytic material throughout its depth disposed over a first portion of the substrate. Other portions of the catalyst element may have a second layer consisting of a catalytic material and a third layer consisting of a thermal barrier coating composition depending on a stage of combustion with a combustion environment.
