Abstract: Disclosed is an apparatus and method of making molten glass. The apparatus includes a glass former having a slot orifice design to deliver a glass ribbon. The slot orifice design can include a transition section, a slot extension, and external structural reinforcements. In some embodiments, the orifice opening distance of the slot extension varies along the width of the orifice. In some embodiments, the orifice has an orifice opening distance that is smaller at the center of the slot extension than at the edges of the slot extension, which limits glass flow at the center of the slot extension. Also disclosed is a method of making glass using the disclosed apparatus.

Abstract: A method for forming a glass sheet with reduced inclusions is disclosed. The method includes flowing molten glass over converging forming surfaces of a forming body positioned within an enclosure. The forming body is heated with a plurality of heating elements separated from the forming body by an inner wall of the enclosure. The temperature T2 at the bottom of the forming body is decoupled from the temperature T1 at the top of the forming body by an insulating thermal barrier positioned between two adjacent heating elements of the plurality of heating elements such that a change in T2 does not cause a substantial change in T1.

Abstract: A glass manufacturing apparatus including a forming apparatus having a forming body and a directly electrically heated edge director assembly attached thereto, the edge director assembly configured to direct a flow of molten glass from the forming body. The edge director assembly includes a plurality of bus bar assemblies connected thereto and configured to receive an electrical current. The electrical current may be a three-phase electrical current. The bus bar assemblies are supported by three-axis support assemblies that support movement of the bus bar assemblies along three orthogonal axes.

Abstract: An assembly provides electrical current to molten glass in a glass melting tank. The assembly includes a structure having an electrode that is in contact with the molten glass, and a fluid-cooled connection apparatus. The fluid-cooled connection apparatus includes a first connection element electrically connected to a current source and a second connection element electrically connected to the current source, where the first and second connection elements are spaced apart from each other; and an electrical cross-connect strut having a first end secured to the first connection element and a second end secured to the second connection element. The assembly also includes a bus bar electrically connected to the fluid-cooled connection apparatus and to an electrode. The current source provides a current to the molten glass via the structure and the electrode for heating the molten glass through resistive heating.

Abstract: A glass manufacturing apparatus includes a delivery tube terminating at a lower end in a delivery slot. A stream of molten material is delivered along a travel plane in a travel direction. A first plate is positioned adjacent the lower end of the delivery tube on a first side of the travel plane. The first plate includes a first edge extending adjacent the travel plane and a first thermal expansion slot extending from the first edge to a first interior. A second plate is positioned adjacent the lower end of the delivery tube on a second side of the travel plane. The second plate includes a second edge extending adjacent the travel plane and a second thermal expansion slot extending from the second edge to a second interior. The second edge is spaced apart from the first edge to define a delivery opening through which the delivery tube extends.

Abstract: Disclosed is an apparatus and method of making molten glass. The apparatus includes a vessel for conveying the molten glass and at least one flange (100) configured to supply an electric current to the vessel through the flange (100), the flange (100) including a first ring (112) extending completely around the vessel in a closed loop, the first ring (112) comprising a first portion (118) including a first thickness and a second portion (128) including a second thickness different from the first thickness, wherein the first portion (118) and the second portion (128) overlap in a plane of the flange (100) such that at least a portion of the first portion (118) is positioned between at least a portion of the second portion (128) and the vessel wall, and neither the first portion nor the second portion extends completely around the vessel. Also disclosed is a method of making glass using the disclosed flange. When the vessel comprises two flanges each connected to an electrode portion (116), current is more uniformly distributed about the vessel, which prevents hot spots.
