  • Cutting bead for a saw rope
    Patent number: 10703015
    Abstract: A cutting bead (13) for a saw rope (15) comprises a geometrically defined cutting portion (2) and tapers from the geometrically defined cutting portion (2) contrary to a sawing direction. With such cutting beads (13), a saw rope (15) is formed. In a method for manufacturing a saw rope (15), a cutting element (1) with a geometrically defined cutting portion (2) and an abrasive element (6) with a geometrically undefined cutting portion (14) or a neutral element (8) are joined. With the cutting element (1) and the abrasive element (6) or the neutral element (8), a cutting bead (13) is formed. The cutting bead (13) is joined onto the support rope (16).

  • Polyurethanes containing sulphide groups, polymeric mixtures based thereon, production and use thereof
    Patent number: 7129288
    Abstract: Novel polyurethanes containing sulfide groups which comprise at least one group of the general formula I in the polymer main chain and/or at least one group of the general formula II incorporated at the chain end: —X—A—S—B—Y—??(I) —X—A—S—B—YH??(II) in which the variables have the following definitions: S is the sulfur atom; X and Y independently of one another are oxygen atoms, sulfur atoms or groups —NZ where Z is the hydrogen atom or an alkyl radical of 1 to 10 carbon atoms; and A and B independently of one another are divalent organic radicals; novel polymer mixtures based thereon, and the use of the novel polyurethanes and polymer mixtures and dispersions thereof for the preparation of coating materials, adhesives and sealing compounds.
