    摘要: Porous metal compacts suitable for use as electrodes are formed through the reduction of a metal billet consisting of multiple filaments of an appropriate valve metal, preferably tantalum, contained within, and spaced apart by, a ductile metal, preferably copper. The filaments are elongated and substantially parallel within the billet. The array of valve metal filaments within the billet is surrounded by a continuous layer of valve metal. This metal is preferably, but not necessarily, the same as that which forms the filaments. The valve metal layer preferably completely surrounds the filament array circumferentially and runs the full length of the filaments. The layer is separated from the array by the same ductile metal that serves to separate the filaments from each other. This same ductile metal forms the surface of the billet, preventing exposure of the valve metal layer. The billet is reduced by conventional means, such as extrusion and wire drawing, the composite product is cut into short lengths, and the ductile metal separating the valve metal components of the composite is removed, preferably by leaching in mineral acids. The filaments are constrained within the valve metal tube, making handling during subsequent capacitor manufacture much less difficult than if the filaments were allowed to move freely.

    摘要: A Nb3Al superconducting wire and method for fabricating the same wherein Nb and Al powders in combination, or Nb—Al alloy powders are encapsulated in a metal tube, preferably copper or copper-alloy (e.g., CuNi), and the resultant composite is processed by conventional means to fine wire. Multifilamentary composites are produced by rebundling of the powder-filled wires into metal tubes followed by conventional processing to wire of a desired size. It is required for the use of Nb and Al powders in combination that the Nb and Al powder particle size be less than 100 nm. In the use of Nb—Al alloy powders, it is preferred, but not required, that the powder particle size be similarly of a nanometer scale. The use of nanometer-scale powders is beneficial to wire fabrication, allowing the production of long wire piece-lengths. At final wire size, the wires produced by practice of the present invention are heat treated at temperatures below the melting point of copper (1083° C.), with the heat treatment causing conversion of the powder cores or filaments to the A15 superconductor Nb3Al. The resulting superconducting wires display critical superconducting properties previously achievable only by methods employing temperatures well in excess of the melting point of copper.

    摘要: A method for providing logically-consistent computer file backups in an operating environment whose file backup provisions rely on application programs recognizing a freeze writes command but where the operating system also hosts programs that do not recognize such a command. The method intercepts a system level command issued during the backup process that signals the file system manager to flush write operations cached in memory and hold any subsequent write operations. (“Flush and Hold Writes”). File write operations are then monitored to find a quiescent period, which signals that all current file transactions are complete. Application level write operations are halted, preventing any further file transactions. The Flush and Hold Writes Command is then allowed to pass to the file system and volume manager so that these operation system components can flush to permanent storage any write operations that are cached in memory and hold any new write operations.
