  • Electric power cable
    Patent number: 9029704
    Abstract: An electric power sea cable including at least one cable core. The cable core includes an electric conductor, an electric insulation surrounding the conductor, and a protective sheath surrounding the electric insulation and acting as a water barrier. At least one outer layer surrounds the at least one cable core. The protective sheath is made of metal and the electrical power sea cable includes at least one friction reducing layer surrounding the at least one cable core and arranged inside of the at least one outer layer.

  • Method in drying of paper
    Patent number: 6742280
    Abstract: A method in consolidation and drying of paper. A wet web is contacted with superheated steam, whose temperature is 200-600° C. for the purpose of reducing, by heat transfer from the superheated stream, the water content of the web by evaporation of a substantial part of the water in the same. The wet web is supported and transported by means of a heat-conductive, gas-impermeable belt whose width is equal to or exceeds the width of the web, and jets of the superheated steam are directed towards the side of the web facing away from the belt.
