  • Patent number: 8597766
    Abstract: A process for the manufacture of a decorative surface element, which element comprises a base layer, a decor and a wear layer of a UV or electron beam curing lacquer. One or more structured surfaces, forming embossing surfaces of one or more rollers or moulds, are positioned on top of the decorative lacquered surface, possibly after having cured the lacquer to a desired viscosity, and are continuously or discontinuously pressed on to this. The lacquer will be provided with a surface structure which enhances the decorative effect of the decor. The wear layer is then completely cured.

  • Patent number: 8598493
    Abstract: The invention relates to a heating system (190) for a switch (4) of a trackway (3) and comprising applicable electrically operating heater elements (2; 100; 103; 300). Said electrical heater elements (2; 100; 103) are arranged selectably connectable to a branch network (104) of electric connections extending along the switch (4) in question and intended for the connection of a desired number of heating plates (2) for the track railbase (23), friction-plate heaters (100) as well as supporting cleat heaters (103) to a relevant supply bar (110) for current extending along the length (L) of the switch.

  • Patent number: 5118289
    Abstract: A hot-isostatic press adapted for rapid cooling of the hot zone after completed pressing and sintering of the material includes a pressure vessel, end closures, and a hot zone surrounded by thermal barriers. Between the thermal barriers and the pressure vessel with end closures there are colder spaces. At least one connection, located in the lower part of the thermal barrier and provided with a valve between the space next to the pressure vessel and the space below the bottom thermal barrier, is provided with an externally controllable valve. In the upper part of the thermal barrier there is an opening with a relatively large cross section and a valve is provided for the opening, which comprises a heat-insulated portion.
