    Assignee: TATA STEEL NEDERLAND TECHNOLOGY B.V.
    Inventors: Pieter Baart, Jan Bottema, David Thomas Allan Matthews
  • Patent number: 11352688
    Abstract: A method of manufacturing a hot dip coated steel strip, wherein coating takes place by leading the strip through a bath of molten metal including Al, the remainder of the metal being Zn, inevitable impurities and optionally a maximum of 0.3% of one or more additional elements, wherein the composition of the bath is controlled so as to have an aluminium content of more than 0.50%.

  • Publication number: 20030231790
    Abstract: A computerised method is described for analysing a medical image to detect the presence of a cancer having a radiographic density close to the radiographic density of normal tissue. The method includes processing the image so as to obtain feature measurements for plural features of different pixel neighbourhoods within a region of the image, each pixel neighbourhood including a pixel having a local minimum intensity value. The feature measurements are used to classify each pixel neighbourhood as one of plural neighbourhood categories. Classification information for each neighbourhood category is then processed to thereby calculate parameters for the region. At least one of the region parameters are used to predict the presence of a cancer.

  • Patent number: 5814395
    Abstract: A metal-polypropylene-metal laminate, in which the metal sheets are steel or aluminum is provided which is suitable for cold-forming followed by heat treatment at at least 135.degree. C., e.g. for use in vehicle bodywork. To achieve this, the polypropylene of the core of the laminate has a yield stress at the heat treatment temperature of not less than 2 MPa, and has shape stability such that in a standard shape stability test at the heat treatment temperature it changes shape by not more than 0.5.degree.. A bonding agent between the polypropylene core and the metal sheets is suitably one having a thermosetting component and a polypropylene thermoplastic component.

    Assignee: Hoogovens Hylite BV
    Inventors: Maria E. Soellaart-Roelofsen, Jan Bottema
  • Patent number: 5306566
    Abstract: The method of inhibiting the reduction of the bond strength by water of a metal-thermoplastic polymer-metal sandwich, where the thermoplastic core contains carbon to carbon double bonds, by incorporating 0.01 to 1.0% of a fatty acid component which comprises at least one fatty acid as an additive.
