US Patent:

6345485, Feb 12, 2002

Filed:

Feb 7, 2000

Appl. No.:

09/499145

Inventors:

Bradley P. Boone - Pittsburgh PA
Stephen L. Crandell - Cranberry Township PA
Jack B. McCandless - Natrona Heights PA
David E. Singleton - Natrona Heights PA

Assignee:

PPG Industries Ohio, Inc. - Cleveland OH

International Classification:

E04C 254

US Classification:

5278613, 52456, 527861, 5278611, 526569, 526568, 526565, 5220461

Abstract:

A multi-sheet glazing unit includes a closed spacer frame, the spacer frame has one side having a pair of legs joined to a base to provide the spacer frame with a U-shaped cross-section. An inner sheet has an edge mounted in an edge receiving member mounted between the legs of the U-shaped side of the spacer frame. The remaining edges of the inner sheet are within the interior of the closed spacer frame and spaced from the spacer frame. The inner sheet is held within the spacer frame by sheet retaining members mounted to the spacer frame. A sheet e. g. glass sheet is secured by a moisture-impervious adhesive to outer surface of each of the legs of the spacer frame. One type of sheet retaining members has a horizontal member and a vertical member, and a locking member. The locking member is mounted on the horizontal member spaced from the vertical member to form a groove to hold the inner sheet within the closed interior of the spacer frame. Another type of the sheet retaining member includes a pair of flexible fingers mounted on a platform member, angled away from the platform member toward one another and having their ends spaced from one another to provide a groove to hold the inner sheet within the closed interior of the spacer frame.

Abstract:

A method and article are disclosed wherein a substrate is provided with a photocatalytically-activated self-cleaning surface by forming a photocatalytically-activated self-cleaning coating on the substrate by spray pyrolysis chemical vapor deposition or magnetron sputter vacuum deposition. The coating has a thickness of at least about 500 Angstroms to limit sodium-ion poisoning to a portion of the coating facing the substrate. Alternatively, a sodium ion diffusion barrier layer is deposited over the substrate prior to the deposition of the photocatalytically-activated self-cleaning coating to prevent sodium ion poisoning of the photocatalytically-activated self-cleaning coating. The substrate includes glass substrates, including glass sheet and continuous float glass ribbon.
