  • Patent number: 9022765
    Abstract: A vibrating machine for producing a molded body by compacting a granular raw mixture includes an oscillatable vibrating table configured to receive a molding box. A clamping device is produced by at least two clamping closures, each including: a pivot bracket having a lower end being pivotally mounted on the vibrating table and an upper end including a cranking which is directed outward; a double-acting hydraulic pivot cylinder pivotally mounted on the vibrating table; a two-armed rocker arm pivotally connected to the pivot bracket and including an inner part that cooperates with the molding box and an outer part that cooperates with the hydraulic pivot cylinder; and a compression spring disposed between the cranking and the outer part of the rocker arm such that the rocker arm releases from a position closing the respective clamping closure upon a pressure in the hydraulic pivot cylinder being relieved.

  • Patent number: 8499821
    Abstract: A method for the detection and classification of surface defects on continuously cast products using topographical information about the appearance of continuously cast surface defects and/or flaws are determined with respect to their exact position, evaluated with respect to their location and dimensions, and eliminated in accordance with the evaluation prior to further machining of the product, or are prevented by optimizing the process. The defects and/or flaws on the slab surface of the continuously cast preliminary product are detected and are stored with respect to their exact position and a detection of defects and/or flaws on the finished product is carried out and stored with respect to their exact position, and in that the information from the preliminary product is then compared with the information from the surface inspection on the finished product.

  • Patent number: 5013591
    Abstract: A bituminous building sheeting which is compatible with hot mopping bitumen and bituminous cold adhesives and whose covering mass is modified with APP and IPP. The mass, homogenized under high shear forces is cooled off after the application of 180.degree. to 200.degree. C. at a cooling speed of not more than 120 K/min. Polymer spherulites form on the surface thereby which improve the adhesiveness and prevent oily components from exuding out of the bitumen.
