Abstract: A flange (13) for use in direct resistance heating of a glass-carrying vessel (10), such as a finer, is provided. The flange comprises a plurality of electrically-conductive rings which include an innermost ring (140) which is joined to the vessel's exterior wall (12) during use of the flange and an outermost ring (150) which receives electrical current during use of the flange. The innermost ring (140) comprises a high-temperature metal which comprises at least 80% platinum and the outermost ring (150) comprises at least 99.0% nickel. This combination of materials both increases the reliability of the flange and reduces its cost. In certain embodiments, the flange can also include one or more rings (190) composed of a platinum-nickel alloy which has a lower thermal conductivity than platinum or nickel and thus can serve to reduce heat loss through the flange.
Abstract translation: 提供一种用于玻璃输送容器（10）的直接电阻加热的凸缘（13），例如更细的。 凸缘包括多个导电环，其包括在使用凸缘期间连接到容器的外壁（12）的最内环（140）和在使用凸缘期间接收电流的最外环（150） 。 最内环（140）包括高温金属，其包含至少80％的铂，最外环（150）包含至少99.0％的镍。 这种材料的组合既增加了法兰的可靠性又降低了成本。 在某些实施例中，凸缘还可以包括由铂 - 镍合金组成的一个或多个环（190），其具有比铂或镍更低的热导率，因此可用于减少通过凸缘的热损失。

Abstract: In the formation of sheet glass by the overflow downdraw process, the width of usable sheet glass is maximized by downwardly flowing edge portions of the sheet over web-like members and thereafter over extensions which intersect with and are downwardly inclined relative to the web-like members to thin edge portions of the glass flow and maintain sheet width. The extension members are preferably removably attached to the web-like members, greatly facilitating replacement of the more easily damaged extension members.

Abstract: Methods for controlling thickness variations across the width of a glass ribbon (104) are provided. The methods employ a set of thermal elements (106) for locally controlling the temperature of the ribbon (104). The operating values for the thermal elements (106) are selected using an iterative procedure in which thickness variations measured during a given iteration are employed in a mathematical procedure which selects the operating values for the next iteration. In practice, the method can bring thickness variations of glass sheets within commercial specifications in just a few iterations, e.g., 2-4 iterations.

Abstract: Methods and apparatus for controlling the stress in, and the shape of, the glass ribbon (15) formed in a downdraw glass manufacturing process (e.g., the fusion downdraw process) are provided. In certain embodiments, the control is achieved by cooling the bead portions (21a, 21b) of the ribbon (15) at a rate which provides a heat flux Q″b at the thickest part of the bead (23a, 23b) which is given by Q″b=Q″q+ΔQ″, where (i) Q″q is the heat flux at a transverse position adjacent to the bead portion (21a, 21b) at which the ribbon's thickness equals 1.05*tcenter, where tcenter is the final thickness at the ribbon's center line (17), and (ii) ΔQ″≧(tb/tq−1)Q″q+10 kilowatts/meter2, where tb is the thickness of the thickest part of the bead portion. The cooling can take place along the entire length of the ribbon (15) or at selected locations, e.g., in the portion (50) of the draw which includes the glass transition temperature region (31) or the portion (60) of the draw where individual glass sheets (13) are cut from the ribbon (15).
