  • Patent number: 11664517
    Abstract: A planar SOFC cell unit is formed from a plurality of planar elements (1100, 1200, 1300) stacked one above another. The cell unit encloses a cell chamber (1400) that includes a solid oxide fuel cell (2000) configured for electro-chemical generation, compliantly supported within the cell chamber. The plurality planar elements each comprise a thermally conductive material having a co-efficient of thermal conductivity that is a least 100 W/mK such as aluminum or copper. The planar elements are thermally conductively coupled to each other to provide a continuous thermally conductive pathway that extends from perimeter edges of the cell chamber to perimeter edges of the plurality of planar elements. An SOFC stack comprises a plurality of the planar SOFC cell units stacked one above another.

  • Patent number: 9640965
    Abstract: A cable gland assembly for attaching a shielded cable to an electronic enclosure includes a cable gland housing enclosing and in electrical contact with exposed cable shielding of the shielded cable and providing an electrically conductive pathway between the cable shielding and the electronic enclosure. The cable gland housing further encloses a shield pressure ring disposed to hold the exposed cable shielding in contact with the cable gland housing, a weather gasket, and an exposed portion of a cable strength member. The cable gland assembly includes environmental molding disposed within the cable gland housing to bond to and fix in place the exposed cable shielding, shield pressure ring, weather gasket, and exposed cable strength member. An outer molding is disposed around the cable gland housing.

  • Publication number: 20100276103
    Abstract: A core for investment casting processes includes a core having one or more ceramic materials; and an exterior layer of metal material not susceptible to oxidation under investment casting operating conditions. A method for casting a turbine engine component having an internal passageway includes the steps of forming one or more mold sections each having internal surfaces and at least one of the aforementioned cores for forming one or more turbine engine components having at least one internal passageway; assembling the one or more mold sections; introducing a molten alloy into the one or more assembled mold sections; and consuming the metal of the at least one core during the process.

  • Patent number: 7581581
    Abstract: A substrate is coated by applying a first layer atop the substrate and including, in major weight part, a non-refractory first metal. A second layer is applied atop the first layer and includes, in major weight part, a carbide and/or nitride of a second metal. A third layer is applied atop the second layer and comprises, in major weight part, a ceramic. The substrate may be a refractory metal-based investment casting core.

  • Patent number: 6951239
    Abstract: An at least two step heating process is used to strengthen the shell of an investment casting mold including a refractory metal core. The first stage may occur under otherwise oxidizing conditions at a low enough temperature to avoid substantial core oxidation.
