  • Patent number: 8306590
    Abstract: Disclosed is a three layer process for making contact points to a high transition temperature superconductor (HTSC), particularly to (Bi,Pb)2 Sr2 Ca2 CU3019+x with and without silver in the superconductor. The contact structure is a three layer configuration with a perforated silver foil (3) sandwiched between two metal spray gun deposited silver layers (2,5) and subsequent heat treatment in air. The contact has been made on tubes and rods (1). The silver contacts are capable of carrying a continuous current of 200 Amps without adding any substantial heat load to the cryogen used to cool the HTSC. The contact resistance at 4.2 K is in the range of 1.5×10 (hoch?8) to 8.5? 10 (hoch?8) OHM in zero applied filed.

  • Patent number: 8304372
    Abstract: The present invention provides a process for joining oxide-superconducting tubes with a superconducting joint. The process involves the preparation of a partially preformed superconducting material, followed by cold isopressing of the powder of partially performed superconducting material into tube shape and further provided with grooves at both ends of the tubes with a subsequent deposition of a silver layer. The process further involves the lapping of one of the end faces of a pair of said tubes to be joined. These lapped end faces of both the tubes clubbed together on a common silver bush are coated with a paste of the same partially preformed superconducting material in organic formulation. Then these coated end faces are closed pressed together to form a joint. This joint portion and the end portions of the tubes are wrapped with a perforated silver foil followed by deposition of another layer of silver.

  • Patent number: 8287951
    Abstract: A process for preparing a single source solid precursor matrix for semiconductor nanocrystals having the steps of: mixing 0.1-1 Molar of an aqueous/non-aqueous (organic) solution containing the first component of the host matrix with 0.001-0.01 Molar of an aqueous/non-aqueous solution containing the first dopant ions, which needs in situ modification of valency state, dissolving 10-20 milligram of an inorganic salt for the in situ reduction of the first dopant ion in the solution, addition of 0.001-0.01 Molar of an aqueous/non-aqueous solution of an inorganic salt containing the dopant ions which do not need modifications of their valency state, addition of 0.1-1 Molar of an aqueous/non-aqueous solution of an inorganic salt containing the second component of the host material, addition of 5-10% by weight of an aqueous solution containing a pH modifying complexing agent, to obtain a mixture, and heating the mixture to obtain a solid layered micro-structural precursor compound.

  • Publication number: 20120253780
    Abstract: Emulating a NIC for packet transmission on hardware RSS unaware NICs in a multi-core system enables each of a plurality of slave packet engines to emulate a NIC for packet transmissions locally even though the actual NIC transmissions from the queue are handled by a master packet engine only. Each slave packet engine treats a local software-implemented transmission queue as a device queue and uses the local queue to keep track of status of data from the packet engine in the device output queue, handled by the master packet engine on behalf of the slave packet engines. As the master packet engine transmits the data from the queue and the status of the queue changes, the master packet engine and the slave packet engines may use pointers to keep track of which data packets are transmitted, which data packets are drained and which data packets are still in the queue.
