  • Publication number: 20020040373
    Abstract: The invention relates to a system for managing and processing digital media by means of an electronic data processing installation. The system consists of a data bank, in which digital media such as pictures, texts, charts, product data etc. are filed and managed in a standardized, neutral data bank format. The different digital media can be converted into the data bank format by means of suitable input and output filters. The media are managed in the data bank in the form of linked data objects. The linkages of the data objects define the layout of documents which can be output for publication purposes by means of suitable output routines in different output formats such as, for example Postscript and HTML.

  • Patent number: 4228223
    Abstract: A nickel-base wear and corrosion resistant alloy is provided containing by weight about 20% to 35% Cr, about 1% to 8% Si, about 1.7% to 3.5% C, 0 to 15% W and the balance essentially at least about 40% nickel, the amount of carbon present in said composition being stoichiometrically related to the chromium content to provide carbides based on the formula M.sub.7 C.sub.3, wherein M comprises essentially chromium, the amount of chromium in said M.sub.7 C.sub.3 compound ranging from about 65% to less than about 100% of the total chromium in said composition, the melting point of said alloy being less than about 1350.degree. C. The alloy has particular use in welding consumables for hard facing, for valve seats, for wear resistant sleeves and bushings (castings) and other uses.
