Abstract: A method of forming a glass sheet comprises: (a) forming a ribbon of glass from molten glass with a pair of forming rollers; (b) reducing horizontal temperature variability of the ribbon of glass to be 10° C. or less across 80 percent of an entire width of the ribbon of glass before the ribbon of glass cools to a glass transition temperature; (c) controlling a cooling rate of the ribbon of glass while the ribbon of glass moves vertically downward within a setting zone such that the ribbon of glass has a first average cooling rate before the ribbon of glass cools to the glass transition temperature and a second average cooling rate after the ribbon of glass cools to the glass transition temperature, the first average cooling rate being less than the second average cooling rate; and (d) separating a glass sheet from the ribbon of glass.

Abstract: A linkage member to link lamps; said lamps being of the kind which comprise electrical contact points located at their first end and no external electrical contact points at their second end; said linkage member comprises a first portion configured to attach to the electrical contact points of a first lamp and to cover at least in part said electrical contact points; and a second portion configured to connect to a second lamp at an end which has no external electrical contact points.

Abstract: The invention relates to a linkage member (10) for linking articles together during a process for coating the articles. The linkage member (10) has a first and second end (12), each end (12) of which is configured to receive and about end portions of successive articles to be coated and to prevent coating of the end portions. Each linkage member (10) is primarily formed from a material such as a perfluorinated polymer, which imparts low thermal conductivity to the linkage member (10). An outer layer of conductive material, such as steel, can be provided to enable heat to be transferred rapidly across the surface of the linkage member (10). The linkage member (10) can he substantially cylindrical in shape with at typical diameter of 15-30 mm and height of 12-15 mm.
