  • Patent number: 8703894
    Abstract: The present invention relates to fluorocarbon polymer-free preparations (Z) based on water and/or organic solvents and their use as a finish on flat materials, containing (1) 10-90% of a reaction product (S) prepared by reacting a component (A) with a partially blocked or non-blocked di-, tri- or polyisocyanate (IC) and (2) 10-90% of a C8-C28-alkyl groups containing organopolysiloxane, (3) 0-45% of a blocked or non-blocked di-, tri- or polyisocyanate, and (4) if appropriate customary emulsifiers. When used as a finish on flat materials, the preparations endow the treated flat materials with durable hydrophobic properties.

  • Patent number: 6118071
    Abstract: A device for electrically connecting the frame of a switching cabinet in which the cabinet housing is connected to the door by contact elements which are thereby electrically connected to the frame sections of the frame-like borders of the cabinet housing facing the door and are supported resiliently as well as electrically against the closed door. Specially designed contact springs can be used to create contacts between a subsequently fitted standard switching cabinet provided with a surface protection layer and the frame or cabinet housing in the door closure area.
