Abstract: A method for decreasing the effective magnetic filament sizes for high current internal tin Nb3Sn superconductors. During processing composite rods preferably comprised of copper clad Ta rods of approximately the same dimensions as the hexes in the designed filament billet stack are used as dividers in the subelement. Along with the Ta rods, Ta strips are strategically situated against the Nb or Nb alloy barrier tube which surrounds the subelement. The use of Ta as a spacer instead of copper prevents any reasonable likelihood of bridging of the superconducting phases formed after final reaction.

Abstract: An improvement is disclosed in the method for producing a multifilament (Nb, Ti)3 Sn superconducting wire by the steps of preparing a plurality of Nb or Nb alloy rods where Nb or Nb alloy monofilaments are encased in copper or copper alloy sheaths; packing the Nb or Nb alloy rods within a copper containing matrix to form a packed subelement for the superconducting wire; providing sources of Sn, and sources of Ti within said subelement; assembling the subelements within a further copper containing matrix; and diffusing the Sn and Ti into the Nb or Nb alloy rods to form (Nb, Ti)3 Sn. The method is improved by diffusing the Ti into the Nb from a minor number of Ti dopant source rods which are distributed among the Nb or Nb alloy rods.

Abstract: A device and method for use as an adjunct in assuring that a manufactured wire is substantially free of internal flaws. A plurality of successively adjacent wire bending stations are provided, where each station includes means for bending the wire into bending planes which are different for each of the stations. The wire is passed through the successive stations, whereby the different bending planes at each station subject the wire at each station to tensile bending strain at portions of the wire cross-section which are different for each station. As a result the probability is increased that a given internal flaw in the wire will be exposed to the tensile bending strain condition as the wire passes through the successive stations, increasing likelihood of breakage of the wire at the flaw or of flaw magnification to improve detection of the flaw during subsequent wire inspections.

Abstract: A packet timing method and apparatus for use with a system for controlling digital TV program start time. An encoder inserts a program clock reference (PCR) timing field, in at least two intervals in transport packets. A decoder generates a decoder-clock signal from the PCR timing signal, which has the same frequency as an encoder-clock signal used for encoding. In response to the PCR timing field, a rate of consumption of data is synchronized with a rate of production of data, and chroma sub-carrier is synchronized.

Abstract: A video system for providing a large number of video streams. The video system includes a video server and dividing means. Storage means, a switch and control means are located at the video server. The video server has a plurality of central-processing units (CPUs). The dividing means divides a plurality of input video-streams entering the video system, and sends the divided plurality of input-video streams, with each divided video stream identified with a separate Ethernet address, to the video server. The storage means stores an input video-stream of the plurality of input video-streams as a stored-video stream. The switch routes an input-video stream of the plurality of input-video streams to the storage means. The control means controls the storage means to replay the stored-video stream and to control portions of the stored-video stream at an appropriate time, and controls the plurality of CPUs at the video server to work in parallel.

Abstract: Web pages and other Internet information resources are retrieved from a one-way broadcast signal such as a broadcast television signal. A user selects from a range of available information, including hypertext markup language (HTML) pages, which is carried in the broadcast stream by invoking a command which is defined according to a uniform resource locator (URL) format. Table mapping data is carried in the broadcast signal and provides a broadcast address corresponding to the URL of the user request signal for use in identifying a location in the broadcast signal from which the desired information can be retrieved. The broadcast address may provide information regarding a frequency, packet identifier, satellite, transponder, cryptographic scheme, modulation scheme, data rate, error correction scheme, page number or other relevant criteria associated with the broadcast signal which must be known to retrieve the requested information. The system has the look and feel of a two-way Internet connection, and is compatible with existing transmission schemes.
