  • CONVERSION COATINGS FOR METAL SURFACES
    Publication number: 20190145009
    Abstract: An aqueous treatment solution for producing conversion coatings on metal surfaces, in particular on zinc or zinc alloy surfaces, contains: Cr(III) ions in an amount of 0.1 g/l to 8.0 g/l; zirconium and/or titanium ions in an amount of 0.1 g/l to 15 g/l; organosilane-modified silicon oxide nanoparticles in an amount of 0.1 g/l to 50 g/l; and fluoride ions in an amount of 0.1 g/l to 15 g/l.

  • Apparatus and method for the thermal treatment of substrates
    Patent number: 9214367
    Abstract: The application describes an apparatus and a method for the thermal treatment of substrates, in particular thin film substrates for photovoltaic applications. The apparatus comprises at least one substrate carrier for supporting a substrate, a heating unit having at least one heating element for heating a substrate located on the substrate carrier and at least one heating element carrier for supporting the at least one heating element. The heating element carrier is designed to allow a local change in distance between the substrate carrier and the heating element, so as to be able to provide locally different heating intensities. In the method such a change in distance is carried out during the thermal treatment.

  • Transport device and method of transporting to-be-processed elements through a high-temperature zone
    Publication number: 20030183491
    Abstract: The present invention relates to a transport device for transporting to-be-processed elements through a high-temperature zone and a corresponding method. The transport device operates according to the walking beam principle, with thin, elongated carrier elements made of a flexible material, which are maintained under tensile stress along the longitudinal axis of the carrier elements, being provided instead of conventional walking beams.
