  • Architectural electrochromic pane
    Patent number: 5889608
    Abstract: This invention relates to an electrically controllable solar building pane composed of two panels spaced apart by a layer of an intermediate gas, the panel facing towards the outside of the building being constituted of a variable transmission system of the electrochromic type comprising two transparent substrates composed, notably, of glass sheets, joined together by an ion-conducting organic polymer and coated on the jointing face with transparent electrically conducting films and films of anodic and cathodic electrochromic materials.
    Type: Grant
    Filed: June 12, 1997
    Date of Patent: March 30, 1999
    Assignee: Saint-Gobain Recherche
    Inventors: Bernard Buffat, Francis Defendini, Christian Padoy, Jean-Pierre Beaufays, Jean-Marie Labbe

  • Glass substrate coated with thin multifilms for protection against solar radiation
    Patent number: 5652046
    Abstract: Glass composites, containing a glass substrate (1) on which is deposited an underlying film (2) based on tantalum oxide, titanium oxide or tin oxide, on which is deposited a functional film (3) based on an alloy of chromium and nickel or based on tantalum, on which is deposited an overlying film (4) based on titanium oxide, titanium nitride or tantalum oxide, provide effective protection against solar radiation while exhibiting excellent wear and corrosion resistance.
    Type: Grant
    Filed: August 7, 1996
    Date of Patent: July 29, 1997
    Assignee: Saint-Gobain Vitrage International

  • Rotary sputtering cathode
    Patent number: 5158660
    Abstract: A vacuum sputtering cathode has a hollow structure (2) able to rotate about its axis and a magnetic confinement circuit (3) arranged peripherally about said structure. The cathode according to the invention is particularly suitable for the rapid dissipation of the thermal energy given off by the sputtering process and in particular for the sputtering of metals with a low melting point.

  • Process for producing a transparent layer with low resistivity
    Patent number: 5011585
    Abstract: A method for depositing on glass, by reactive cathode sputtering, a layer of indium tin oxide with low resistivity and high transparency, where a layer with at least a minimum intrinsic absorption coefficient is deposited and then a heat treatment, including of one reducing phase, is performed.
