  • Patent number: 8950211
    Abstract: Subassemblies are arranged in the interior of a closed housing. The housing has an air inlet via which air-conditioning air is guided into the interior of the housing. The housing contains a fan via which the air used for the air conditioning of the subassemblies is guided to the outside from the interior of the housing. In addition to a fan input opening, the fan has at least two fan output openings wherein a rotatably mounted screen is arranged in the interior of the fan. By variably adjusting the position of the screen, the air sucked in via the fan input openings is optically guided via at least one of the fan output openings.

  • Patent number: 8911561
    Abstract: A method for removing liquid from a surface of a disc includes, rotating the disc article about an axis perpendicular to the disc's main surface, supplying liquid from a supply port, moved across the substrate towards the edge of the disc, onto the rotated disc, supplying a first gas flow through a first gas supply port onto the disc article to an area whose center has a distance to the center of rotational movement of not more than 20 mm, the area being covered with a liquid layer thereby opening the liquid layer at a discrete area, and supplying a second gas flow through a second gas supply port moved across the substrate towards the edge of the substrate onto the rotated disc wherein the distance of the second gas supply port to the center is lower than the distance of the liquid supply port to the center.

  • Publication number: 20130273375
    Abstract: The present invention relates to novel waterborne adhesives which are polymerisable by UV light and are capable of being activated by heat, and which particularly display good adhesion to difficult substrates, such as ethylene vinyl acetate copolymers (EVA) with a low vinyl acetate content, or rubber. The invention further provides a novel method in which, after the application of the waterborne adhesive to an article and drying, irradiation with UV light and at the same time or thereafter activation by heat are performed. The adhesive film which is irradiated and activated in this way is then bonded to a further article. The invention also provides the use of the adhesives to make items such as shoes.

  • Publication number: 20130213059
    Abstract: A method for compressing a cryogenic medium, in particular hydrogen, oxygen, nitrogen or argon is described. The cryogenic medium is compressed in two compressor stages from an initial pressure to a final pressure by way of an intermediate pressure, such that the first compressor stage is designed as a cryogenic compressor stage. The cryogenic medium is advantageously compressed to a pressure between 30 and 70 bar in the first compressor stage and in the second compressor stage is compressed to the desired final pressure by means of a hot gas compression.
