Patent number: 6942351Abstract: A process for forming a silver coating on a surface of a vitreous substrate is described. The process comprises an activating step in which said surface is contacted with an activating solution, a sensitising step in which said surface is contacted with a sensitising solution, and a subsequent silvering step in which said surface is contacted with a silvering solution comprising a source of silver to form the silver coating. The process is characterised in that said activating solution comprises ions of at least one of bismuth (III), chromium (II), gold (III), indium (III), nickel (II), palladium (II), platinum (II), rhodium (III), ruthenium (III), titanium (III), vanadium (III) and zinc (II).Type: GrantFiled: May 28, 2004Date of Patent: September 13, 2005Assignee: GlaverbelInventors: Pierre Laroche, Pierre Boulanger, Christian Dauby

Patent number: 6749307Abstract: A domestic or vehicle rearview silvered mirror having a silver coating which is not covered with a protective layer of copper. The silver mirror comprises a glass sheet, tin and preferably palladium at surface of the glass sheet, a silver coating of the surface of the glass sheet and at least one paint layer covering the silver coating. Optionally, tin may be present at the surface of the silver coating adjacent the paint layer and optionally traces of silane may be present at the surface of the silver coating adjacent to the paint layer. Alternate or additional materials may be present at a surface of the glass sheet and alternate or additional materials may be present at the surface of the silver adjacent to the paint layer.Type: GrantFiled: December 16, 2002Date of Patent: June 15, 2004Assignee: GlaverbelInventors: Pierre Laroche, Pierre Boulanger, Christian Dauby

Patent number: 6565217Abstract: A mirror composed of a vitreous substrate having a silver coating formed on a surface thereof produced by a process including the steps of sensitizing the vitreous substrate; activating the vitreous substrate by contacting the vitreous substrate with a solution comprised of at least one ion selected from the group consisting of bismuth (III), chromium (II), gold (III), indium (III), nickel (II), palladium (II), platinum (II), rhodium (III), titanium (III), vanadium (III) and zinc (II); contacting the vitreous substrate with a silvering solution so as to form the silver coating; and applying at least one layer of paint over the silvered substrate. Preferably, the silver coating is not covered with a protective layer of copper.Type: GrantFiled: April 17, 2001Date of Patent: May 20, 2003Assignee: GlaverbelInventors: Pierre Laroche, Pierre Boulanger, Christian Dauby

Patent number: 5374451Abstract: A reflective article such as a mirror or an energy-screening transparent panel comprises a reflective metal coating deposited on a glass substrate. The metal coating comprises a reflective layer of silver and has been treated with a solution containing ions of at least one of the group consisting of: Cr (II); V (II or III); Ti (III or II); Fe (II); In (I or II); Cu (I); and Al (III). Such a treatment affords protection of the reflective coating against corrosion.Type: GrantFiled: August 19, 1993Date of Patent: December 20, 1994Assignee: GlaverbelInventors: Albert Servais, Christian Dauby, Bernard Somerhausen

Patent number: 5240776Abstract: A reflective article includes a glass substrate and a reflective metal coating deposited on the glass substrate including a reflective layer of silver and having a surface stratum which has a population of tin atoms which is augmented as compared with the population of tin atoms (if any) in an underlying subsurface stratum by at least one tin atom per hundred metal atoms thereby conferring on the reflective metal coating an enhanced resistance to corrosion. The reflective layer of silver is treated with an acidified aqueous solution of a stannous salt, which solution is free from opalescence, thereby to augment tin atom population in a surface stratum of the reflective metal coating.Type: GrantFiled: November 1, 1991Date of Patent: August 31, 1993Assignee: GlaverbelInventors: Albert Servais, Christian Dauby, Bernard Somerhausen

Patent number: 4557743Abstract: A method of and apparatus for monitoring the redox state of one or more elements in glass are disclosed in which a working electrode 2 and an auxiliary electrode 7 are immersed in the glass 11 while the latter is molten. A scanning potential is applied to the working electrode, a series of potential pulses is superimposed on said scanning potential, and the resulting current between the electrodes is monitored to give an indication of the redox state of one or more elements in the glass.Type: GrantFiled: August 31, 1984Date of Patent: December 10, 1985Assignee: GlaverbelInventors: Paul Claes, Christian Dauby, Camille Dupont, Luc Van Cangh
