  • Patent number: 7357405
    Abstract: The invention relates to a sliding board, in particular alpine ski or snowboard, with a sliding-board basic body and a binding-receiving plate. According to the invention, the binding-receiving plate is integrated as a supporting part in the central region of the sliding-board basic body, in which it is used, by being surrounded positively at the sides by raised regions of the sliding-board basic body.
    Type: Grant
    Filed: July 28, 2005
    Date of Patent: April 15, 2008
    Assignee: Blizzard Sport GmbH
    Inventor: Wolfgang Leitner
  • Patent number: 7344149
    Abstract: The invention relates to a ski, in particular an alpine ski, with a basic ski body and a binding plate. According to the invention, lateral guide elements are positioned in the mid-section of the basic ski body where the binding plate is to be inserted, and these lateral guide elements each form a lateral guide groove for the binding plates that are inserted in a form-fitting manner between them.

  • Patent number: 4356276
    Abstract: Binder combinations for the formulation of cathodic paints comprising blends of epoxy resins as follows: (A) 40 to 80% by weight of reaction products of epoxy acrylates with basic monoisocyanates; (B) 5 to 30% by weight of reaction products of epoxy amine adducts with unsaturated monoisocyanates, and (C) an epoxy resin modified with a semi-ester of a dicarboxylic acid anhydride and an N-hydroxyalkyloxazolidin and an amine, rendered water soluble through neutralization of the basic groups. The binder combinations as defined have enhanced throwing power and improved stability of the paint tank.

  • Patent number: 4349655
    Abstract: Binders water-dilutable upon neutralization with inorganic and/or organic acids comprising the reaction product of (A) a monoadduct of an N-hydroxyalkyloxazolidine and a diisocyanate with (B) a hydroxyl group containing polymer, the ratio of (A) and (B) adjusted to provide a final product with an amine value sufficient to provide water dilutability upon acid neutralization, and a process for the formation of the binders, is described. The binders, upon stoving, provide films with good resistance characteristics and have reduced losses.

    Inventors: Wolfgang Leitner, Georg Pampouchidis, Anton Bleikolm
  • Patent number: 4327200
    Abstract: Binders water-dilutable upon neutralization with inorganic and/or organic acids comprising the reaction product of (A) resins having at least 2 1,2-epoxy groups per molecule and an epoxy equivalent of at least 160; and (B) a semiester of a dicarboxylic acid and an N-2-hydroxyalkyloxazolidine, and a process for the formation of the binders, is described. The binders have sufficient basic groups for neutralization with acids to provide water dilutability, as well as the functional groups required for crosslinking of the binders. The binders upon stoving provide films with good resistance characteristics and have reduced losses.
