Abstract: A glass or glass-like substrate having a contact-killing, non-leaching antimicrobial effective amount of metal ions contained in at least one surface region thereof, and having a color of b*?+6 on the CIE international color scale is disclosed. The antimicrobial substrate is prepared by providing a metal ion precursor comprising at least one source of antimicrobial effective metal ions dissolved or otherwise dispersed in a carrier material; depositing the precursor onto at least one surface of the substrate; drying the substrate at a temperature of from about 20° C. to about 105° C. by removing volatiles from the metal ion precursor; and heating the resulting substrate at a temperature of about 600-650° C. for 2-5 min. to exchange or otherwise implant antimicrobial metal ions from the precursor and into the glass or glass-like substrate.

Abstract: A continuous, chemical vapor deposition method for producing a coated glass article is disclosed. A glass substrate is advanced continuously, while hot, past first and second treating stations. A non-oxidizing atmosphere is maintained in the vicinity of the first treating station, while an oxidizing atmosphere is maintained in the vicinity of the second station. A non-oxidizing gas which contains a silane, e.g., SiH.sub.4, is directed from the first treating station against a surface of the glass to form a silicon coating on that surface. An oxidizing gas which includes a metal compound in the vapor phase is directed from the second station against the silicon-coated surface of the article.

Abstract: A gas distributor beam includes a plenum and distribution slot surrounded by a generally V-shaped cooling fluid chamber. The circulation of a suitable cooling fluid tends to maintain the plenum and distribution slot at a temperature below four hundred degrees Fahrenheit for the distribution of diborane gas to an upper surface of a heated glass ribbon. Carbon blocks are utilized to stabilize the glass temperature above nine hundred fifty degrees Fahrenheit for the proper deposition of boron on the surface of the glass. Insulation between the carbon blocks and the outer walls of the cooling fluid chamber minimize heat transfer and the shape of the cooling chamber minimizes the exposure of the glass to the lower temperatures of the cooling chamber.

Abstract: The present invention relates to an apparatus and method for directing a constant velocity laminar flow of a fluid along a surface of a planar substrate. The apparatus comprises a plurality of serially arranged, individual passageways interconnecting an inlet and an outlet. The inlet is adapted to be connected to a supply of fluid, while the outlet is positioned adjacent the surface of the substrate for directing the uniform laminar flow of fluid onto the substrate surface. The individual passageways are adapted to vary the velocity of the fluid as it passes through the passageways to ensure that a laminar flow of constant velocity is produced along the surface of the substrate. In the preferred embodiment of the invention, the apparatus is utilized to apply a metal oxide coating to a sheet of moving glass.

Abstract: This application describes a method of treating glass sheets to be stacked, by applying water, a stain inhibiting material such as ammonium chloride, and dry particles of a mechanical separator such as wood flour, to such sheets in a plurality of sequential steps; together with articles resulting from that method.
