Abstract: A thermal barrier coating material contains a compound X that is a cation-deficient-type defective perovskite complex oxide. Unit cells of the compound X each include six oxygen atoms and has a structure in which two octahedrons sharing one oxygen atom are aligned. In the compound X, central axes of two octahedrons that belong to adjacent unit cells, respectively, and are adjacent to each other are inclined relative to each other. A plurality of sets of the two octahedrons that belong to the adjacent unit cells, respectively, and are adjacent to each other are arranged to form a periodic structure in which octahedrons having different inclinations are alternately arranged, and the compound X has a boundary surface at which a periodicity of the periodic structure changes, in a crystal structure thereof.

Abstract: A seismic coupling is provided for coupling a first longitudinal section of plain end plastic pipe to a second longitudinal section of plastic pipe. The coupling is provided in two halves with a left half being initially installed on the plain end of the first section of pipe. An internal shoulder is fused onto the first section of pipe and a right half of the coupling is then fused onto the left half to capture the first end of pipe within the coupling. The second pipe end is then installed within an end opening of the coupling and held in position by a connector installed between the right half of the coupling and the second pipe end. Internal seals are provided for sealing the first and second pipe ends within the interior of the coupling.

Abstract: Customer specific catalogs based on a set of standard catalogs are described. In one aspect, a computer-readable medium includes computer-program-instructions executable by a processor. The computer-program instructions are for implementing an application programming interface (API) to design and/or maintain an electronic catalog that is based on one or more base catalogs. the API includes a create catalog interface comprising a parameter to indicate that a catalog to be created is to be the electronic catalog, the electronic catalog being a virtual catalog.

Abstract: Generating and/or managing customer specific catalogs based on a set of standard catalogs are described. In one aspect, a catalog is generated or managed in view of a catalog schema data structure. The catalog schema data structure includes a first table The first table includes first, second, and third data fields. the first data field indicates a product, category, or variant of a base catalog to include or exclude from a virtual catalog that is derived at least in part from the base catalog. The second data field specifies an inclusion or exclusion rule to apply to the base catalog, product, category, or variant identified in the first data field. The third date if field provides an object ID of the product, category or variant.

Abstract: A burner head assembly for a burner includes a housing having a hollow interior and an exterior. There is a control module within the hollow interior. The module has internal connectors within the hollow interior and external connectors on the exterior of the housing, whereby electrical connections to the module can be made internally and externally with respect to the housing without requiring apertures in the housing and wiring extending through the apertures. For example, the control module may include a circuit board, the circuit board having a portion within the hollow interior and which extends to the exterior. The exterior and interior connectors are connected to the circuit board. The housing may have two portions, the control module being fitted between the two portions of the housing. Preferably the control module is sealingly received between the two portions of the housing.

Abstract: An apparatus and method provide an auxiliary air-conditioning system for a vehicle having a vehicle engine for powering the vehicle and a main air-conditioning system powered by the vehicle engine. The main air-conditioning system includes a main compressor powered by the vehicle engine, an evaporator and a main condenser, the evaporator and the main condenser being connected to the main compressor by conduits suitable for carrying a refrigerant.
