  • Patent number: 8557099
    Abstract: An electrically conductive protective coating or film is provided over the surface of a reflective coating of a solar mirror by flowing or directing a cation containing liquid and an anion containing liquid onto the conductive surface. The cation and the anion containing liquids are spaced from, and preferably out of contact with one another on the surface of the reflective coating as an electric current is moved through the anion containing liquid, the conductive surface between the liquids and the cation containing liquid to coat the conductive surface with the electrically conductive coating.

  • Patent number: 8535501
    Abstract: A protective coating is applied to the electrically conductive surface of a reflective coating of a solar mirror by biasing a conductive member having a layer of a malleable electrically conductive material, e.g. a paste, against a portion of the conductive surface while moving an electrodepositable coating composition over the conductive surface. The moving of the electrodepositable coating composition over the conductive surface includes moving the solar mirror through a flow curtain of the electrodepositable coating composition and submerging the solar mirror in a pool of the electrodepositable coating composition. The use of the layer of a malleable electrically conductive material between the conductive member and the conductive surface compensates for irregularities in the conductive surface being contacted during the coating process thereby reducing the current density at the electrical contact area.

  • Patent number: 6872291
    Abstract: The presence of biological contaminants in a liquid coating composition is determined by measuring the carbon dioxide content of the atmosphere above the liquid and comparing the measured carbon dioxide level to a baseline carbon dioxide level. A biocide can be added to the liquid when the measured carbon dioxide level reaches a predetermined value to control the level of biological contaminants in the liquid coating composition.
