Abstract: A glass tube manufacturing apparatus for manufacturing glass tubing includes a glass delivery tank with molten glass. The glass delivery tank has a bottom opening. A bell has an upper portion with an outer diameter located at the bottom opening. A heating apparatus is at least partially disposed around the bell. The heating apparatus includes a heating portion and a muffle portion located below the heating portion. A lower extended muffle structure extends downwardly from the muffle portion. The lower extended muffle structure extending about a periphery of the glass tubing to manage convective airflow therethrough.

Abstract: A method for making a glass ribbon that includes: flowing a glass into a caster having a width (Wcast) from about 100 mm to about 5 m and a thickness (t) from about 1 mm to about 500 mm to form an a cast glass; cooling the cast glass in the caster to a viscosity of at least 108 Poise; conveying the cast glass from the caster; drawing the cast glass, the drawing comprising heating the cast glass to an average viscosity of less than 107 Poise and drawing the cast glass into a glass ribbon having a width (Wribbon) that is less than Wcast; and thereafter cooling the glass ribbon to ambient temperature. Further, the cast glass during the cooling, conveying and drawing steps is about 50° C. or higher.

Abstract: A bell positioning apparatus for glass tubing manufacturing includes a bell and a support connected to the bell. A bell positioning apparatus is attached to the support and configured to move the support and the bell with at least three degrees of freedom. The bell positioning apparatus includes a platform, a platform frame, and one or more frame legs. A frame leg dimensional stability apparatus maintains a temperature variation within 6.5° C. per meter of distance between each frame leg for an extended period of time, e.g. 4 hours.

Abstract: An apparatus for making a glass sheet using overflow fusion down-draw process comprising an inlet assembly having an elliptic cylindrical section coupled to a transition section which is, in turn, coupled to an open end of an open channel of an isopipe, and an overflow fusion down-draw process for making glass sheet. The glass melt flow has a high surface velocity profile conducive to the formation of a glass ribbon over the surface of the weirs and the wedge side surfaces with the desired mass distribution.
