摘要： An apparatus for delivering a glass stream including a first inner layer and a second outer layer, including a generally vertical orifice, and delivering glass from a second source such that the glass from said second source provides an outer layer about the glass from the first source as it flows through the orifice. A resistance heated tube assembly is made of platinum or material having similar resistance heating properties and extends from a glass source to an orifice through which the glass flows from a glass source for the inner layer. The tube assembly includes a tube portion having an inlet end that communicates with the source for the outer layer and an outlet end that communicates with the source. The tube portion has an axis positioned at any angle ranging between the horizontal and vertical but preferably has an axis which is more vertical than horizontal. Flanges are secured to the ends of the tube portion, and the flanges are connected to an electric power supply. The cross sectional thickness of the flanges is preferably greater than the thickness of the tube portion. Each flange includes an annular groove adjacent its respective end of the tube portion into which the end of the tube portion extends. The flanges are welded to the tube portion. Flange heater modules surround each end of the tube portion.

摘要： Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass includes a first orifice for receiving core glass from a first source. A second orifice is vertically spaced beneath and aligned with the first orifice, and is surrounded by an annular chamber that communicates with the second orifice through the gap between the first and second orifices. A spout delivers casing glass from a second source through a tube to the annular chamber in such a way that glass flows by gravity from the first and second sources through the orifices to form the cased glass stream. A plurality of gas burners are disposed in the spout above the glass pool. The casing glass delivery spout is configured for improved heat transfer to, and improved heat retention within, the casing glass pool within the spout. Specifically, the glass pool surface area is enlarged, and the glass pool depth is reduced. Free space above the glass pool is enlarged to accommodate gas flames from more burners, and to increase surface heat radiation into the glass pool. The housing that supports the spout is designed such that an annular spout support surface engages the spout radially outwardly of the spout opening(s) for reducing heat transfer to the housing from casing glass flowing through the opening.

摘要： A method of reducing bubble lifetime on the free surface of a volume of molten glass contained within or flowing through a vessel including a free volume above the free surface, thereby minimizing re-entrainment of the bubbles back into the volume of molten glass and reducing the occurrence of blisters in finished glass products. The method includes vaporizing a volatile material, entraining the vapor in a carrier gas to form an enrichment gas, and flowing the enrichment gas into the free volume to increase a concentration of the volatile material at the surface of the molten glass in the vessel.

摘要： A method for delivering a coated glass stream having a first inner layer and a second outer layer wherein the method includes providing a vertical orifice, delivering molten glass from a first source through the orifice, providing a gap about the orifice intermediate its upper and lower ends, delivering glass from a second source about the gap such that the glass from the second source flows through the gap to provide an outer layer about the glass from the first source as it flows through the orifice, and controlling the size and shape of the gap parallel to the flow and the size of the gap perpendicular to the flow such that the gap provides sufficient flow resistance and the gap is of sufficient size and shape to prevent clogging. The method includes the step of providing passages for the flow of the glass from the second source and controlling the size and shape of the passages such that the passages are sufficiently large to minimize flow resistance therein and to provide sufficient pressure to force the glass through the gap and provide less resistance than the metering gap. The method also includes providing a plurality of orifices, each having a gap, delivering glass from the first source through each of the orifices, delivering glass from the second source to the gaps and controlling the size and shapes of such gaps.
