  • Patent number: 10265986
    Abstract: The invention relates to a thermal sublimation paper which can be printed with inks containing a sublimatable dye, in particular ink-jet inks, in which paper a hydrophilic thermal transfer layer to be printed is formed on a porous base paper. Thermoplastic particles with an average particle size of between 0.3 and 5 ?m and a melting point of between 35° C. and 190° C. are present in the thermal transfer layer. This thermal sublimation paper can be advantageously produced as follows: an aqueous coating slip is applied to a porous base paper having a Cobb value of between 55 and 150 g/m2, in particular between 70 and 150 g/m2, in a paper-making or coating machine, online or offline, said aqueous coating slip containing thermoplastic particles and constituents suitable for forming a hydrophilic thermal transfer layer, and a drying step is subsequently carried out in order to obtain the thermal sublimation paper.

  • Patent number: 9851146
    Abstract: A dryer section for drying a web of fibrous material is provided, which has at least one drying unit for reducing the moisture content of the web by means of convection drying. The drying unit has at least one nozzle for applying a drying fluid to the web, at least one discharge device for the moist air produced during convection drying, and transport means for moving the web relative to the drying unit. The drying unit has at least one ultrasonic generator, which is arranged, for excitating vibrations in the drying fluid, in the region of the nozzle in such a manner that the reduction of the moisture content by ultrasound can be supported over the entire width of the web.

  • Patent number: 8847835
    Abstract: A radar antenna arrangement, in particular for motor vehicles, is presented, having of a longitudinal waveguide, into which electromagnetic waves are coupled in such a manner that they expand in the longitudinal direction (X) of the waveguide, and an interference structure (12) with a plurality of metallic sections, whereby the interference structure in proximity to the waveguide, at a distance from the waveguide in a first transverse direction (Y) to the waveguide, is arranged at least approximately parallel to the longitudinal direction (X) of the waveguide, so that the interference structure effects an adjusted radiation of the radar waves. The waveguide comprises in the longitudinal direction two metallic surfaces (31, 41) and between these, a dielectric medium (32, 42), whereby the surfaces (31, 41) run in a second transverse direction (Z), which stands both vertically to the first transverse direction (Y) and to the longitudinal direction (X) of the waveguide.
