Patent number: 7060359Abstract: The present invention provides a coating for a transparent substrate which exhibits a “neutral” color through a wide range of angles of incidence of light. The coating employs a base coat adjacent the transparent substrate having a thickness of no more than about 275 ? and may include two reflective metal layers having an intermediate layer of an anti-reflective metal oxide therebetween and an outer anti-reflective layer of metal oxide over the second reflective metal layer. If so desired, the coating of the invention may include an abrasive-resistant overcoat as its outermost layer. This overcoat is desirably formed of an abrasive-resistant metal oxide, such as zinc oxide applied at a thickness which does not significantly affect the optical properties of said coated substrate.Type: GrantFiled: January 3, 2005Date of Patent: June 13, 2006Assignee: Cardinal CG CompanyInventors: Eric Eby, Roger O'Shaughnessy, Robert Bond

Publication number: 20050127034Abstract: The present invention relates to methods and apparatus for removing coatings from generally opposed first and second major surfaces of a substrate. The method includes providing a table having a surface for slidable receipt of the substrate. First and second grinding apparatuses are provided at a mounting portion of the table, opposite one another. As the substrate moves over the table surface, it contacts the first and second grinding apparatuses. The coatings are simultaneously removed from the first major surface with the first grinding apparatus from the second major surface with the second grinding apparatus.Type: ApplicationFiled: October 7, 2004Publication date: June 16, 2005Inventors: Timothy Valek, Roger O'Shaughnessy

Patent number: 6349569Abstract: The present invention provides a method for making a stain-resistant float glass and an apparatus for carrying out such a method. In keeping with this method, SO3 is applied to the upper surface of float glass in an amount efficacious to materially reduce staining of the upper surface of the glass. Optimally, SO3 gas can be applied directly onto the upper surface of the glass. An apparatus of the invention generally includes a downwardly open hood positioned above the upper surface of the glass and having walls defining an enclosure. SO3 gas (either as such or as a reactive mixture of S02 gas and an oxygen-containing gas) is delivered through a delivery tube to the enclosure.Type: GrantFiled: March 18, 1997Date of Patent: February 26, 2002Assignee: Cardinal FG CompanyInventors: Mark Piper, Al Slavich, Chris Granley, Roger O'Shaughnessy

Patent number: 5302449Abstract: The present invention provides a coating for a transparent substrate which exhibits a neutral color through a wide range of angles of incidence a light. The coating employs a base coat adjacent to the transparent substrate having a thickness of no more than about 275 Angstroms and may include two reflective metal layers having an intermediate layer of an anti-reflective metal oxide therebetween and an outer anti-reflective layer of metal oxide over the second reflective metal layer. If so desired, the coating of the invention may include an abrasive-resistant overcoat as its outer most layer. This overcoat is desirably formed of an abrasive-resistant metal oxide, such as zinc oxide, applied at a thickness which does not significantly affect the optical properties of said coated substrate.Type: GrantFiled: March 27, 1992Date of Patent: April 12, 1994Assignee: Cardinal IG CompanyInventors: Eric Eby, Roger O'Shaughnessy, Robert Bond

Patent number: 5296302Abstract: The present invention provides a high transmittance, low emissivity film stack having an overcoat of an oxide of a metal chosen from the group of zinc, tin, indium, or bismuth, or an alloy including one or more of these metals, the oxide being applied in a thickness sufficiently low as to have no significant affect upon the optical properties of the coated substrate. That is, if the overcoat is lost through abrasion or chemical attack, the loss will not significantly affect the optical properties of the coating. The resulting film stack exhibits significantly enhanced durability as compared to a film stack without such an overcoat. In a preferred embodiment, a film stack of the invention includes at least one reflective metal layer, an outer, scratch-resistant metal oxide overcoat, and a metal oxide layer between the silver layer and the overcoat which is less scratch resistant than the overcoat.Type: GrantFiled: March 27, 1992Date of Patent: March 22, 1994Assignee: Cardinal IG CompanyInventors: Roger O'Shaughnessy, Robert Bond

Patent number: 4780164Abstract: The inventon relates to a method of producing a plurality of multi-pane insulating glass assemblies in which the assemblies are formed into a self-supporting unit for further fabrication. Each assembly is provided with at least one exteriorly accessible opening, and the assemblies, supporting one another in surface-to-surface contact, are moved along a conveyor as a unit into a vacuum chamber. Vacuum is drawn on the unit to evacuate each interpane space, following which a gas having coefficient of thermal conductivity lower than that of air is introduced into the chamber to fill the interpane spaces of the glass assemblies. The assemblies as a unit are then conveyed out of the vacuum chamber and the exteriorly accessible openings are sealed.Type: GrantFiled: November 20, 1986Date of Patent: October 25, 1988Assignee: Cardinal IG CompanyInventors: Eric W. Rueckheim, Roger O'Shaughnessy
