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

Patent number: 6964731Abstract: A glass article which has a water-sheeting coating and a method of applying coatings to opposed sides of a substrate are described. In one embodiment, a glass sheet is provided bearing a sputtered water-sheeting coating comprising silica on an exterior surface and bearing a reflective coating on an interior surface. The interior surface of a sheet of glass can be coated with a reflective coating by sputtering, in sequence, at least one dielectric layer, at least one metal layer, and at least one dielectric layer. The exterior surface of the glass can be coated with a water-sheeting coating by sputtering silica directly onto the exterior surface of the sheet of glass. Both the reflective coating and the water-sheeting coating can be applied during the same pass through the same sputter coating apparatus.Type: GrantFiled: February 2, 1999Date of Patent: November 15, 2005Assignee: Cardinal CG CompanyInventors: Annette J.

Patent number: 6939446Abstract: A glass article which has a water-sheeting coating and a method of applying coatings to opposed sides of a substrate are described. In one embodiment, a water-sheeting coating 20 comprising silica is sputtered directly onto an exterior surface of the glass. The exterior face of this water-sheeting coating is substantially non-porous but has an irregular surface. This water-sheeting coating causes water applied to the coated surface to sheet, making the glass article easier to clean and helping the glass stay clean longer. In one method of the invention, interior and exterior surfaces of a glass sheet are cleaned. Thereafter, the interior surface of the sheet of glass is coated with a reflective coating by sputtering, in sequence, at least one dielectric layer, at least one metal layer, and at least one dielectric layer. The exterior surface of the glass is coated with a water-sheeting coating by sputtering silica directly onto the exterior surface of the sheet of glass.Type: GrantFiled: June 17, 2003Date of Patent: September 6, 2005Assignee: Cardinal CG CompanyInventors: Annette J.

Patent number: 6820752Abstract: A stackable, folding transport rack generally including a base, a plurality of supports, at least one foldable A-frame hingedly secured to the base and an optional securing assembly. The base of the transport rack is supported by a plurality of legs bearing supports which are adapted to support the lower edges of objects, such as glass sheets or other sheet materials to be carried by the transport rack. The supports are configured to be as low as possible to the resting surface of the transport rack so as to provide for a minimal lift height for loading and unloading. The low arrangement of the supports also maximizes the size of glass sheets that can be carried and maintains the lowest possible center of gravity. The top of the sheet supports may be cushioned with appropriate resilient material.Type: GrantFiled: January 9, 2004Date of Patent: November 23, 2004Assignee: Cardinal CG CompanyInventors: Marion Michael Jeskey, Michael Jeffery Wade
