  • [专利] Method for solidifying liquid steel slag
    (IN201617030798) The liquid steel slag (2) is poured in at least four successive layers (6 8) comprising a lowermost layer (6) an uppermost layer (7) and at least two intermediate layers (8) in a reservoir (3) and the layers of liquid steel slag are allowed to solidify. After having applied the uppermost layer (7) the solidified steel slag is cooled down more quickly by means of water. The average temperature of each of the intermediate layers (8) is kept at least until the start of the water cooling step and this for at least one hour above a minimum temperature which is equal to or higher than the temperature at which ß dicalcium silicate is formed. In this way more crystalline phases different from dicalcium silicates are formed so that the formation of fines by the transition of ß into ? dicalcium silicates can be considerably reduced. A glassy material and/or a phosphorus containing compound is preferably added to the liquid slag to further reduce the formation of fines.
  • [专利] Method and system for laser hardening of a surface of a workpiece
    (IN201617030807) Method of laser hardening of a surface area of a workpiece such as a surface of a journal of a crankshaft comprising: generating a relative movement between the surface of the workpiece and a laser source to allow a laser spot to subsequently be projected onto different portions of said surface area and during said relative movement repetitively scanning the laser beam (2) so as to produce a two dimensional equivalent effective laser spot (5) on said surface area. The scanning pattern can comprises at least three substantially parallel lines which the laser spot follow in a certain order. When the workpiece comprises several journals having different widths two laser sources (1 1A) may be used to harden the surface area of the wider journals.
  • [专利] Polyester and method for preparing such a polyester
    (IN201617030785) A polyester comprising ethylene 2 5 furandicarboxylateunits has an intrinsic viscosity of at least 0.45 d L/g and has a relative content of carboxylic acid end groups expressed as the fraction of the molar amount of carboxylic acid end groups divided by the sum of the molar amounts of hydroxyl end groups and carboxylic acid end groups in the range of 0.10to 0.70.
