| 065126000 | Discharging molten glass downwardly through orifice | 10 |
| 20090078003 | Free-surface mixing method and apparatus therefor - A method of mixing a viscous liquid comprising flowing the viscous liquid through an aperture to form a stream that falls through a free space volume by gravity. The viscous liquid may be directed through any combination of apertures. The corresponding streams of viscous liquid may be allowed to undergo fluid buckling as the streams fall, with the streams spreading the inhomogeneities and then recombining with each other, thereby mixing the viscous liquid globally and locally. A jet of gas may be directed against the falling streams to intertwine the streams, thereby mixing the viscous liquid. Alternatively, the streams may be manipulated with an electromagnetic field to create intertwining. | 03-26-2009 |

The methods further include the steps of heating the glass melt within a first area of the connecting tube with a first heating device and heating the glass melt within a second area of the connecting tube with a second heating device. Apparatus for making glass are also provided with a first melting furnace, a second melting furnace, and a connecting tube connecting the first and second melting furnaces. Example apparatus include a first heating device configured to heat the glass melt within the first area of the connecting tube and a second heating device configured to heat the glass melt within the second area of the connecting tube. | 05-27-2010 |

| 20110308280 | PANEL-COOLED SUBMERGED COMBUSTION MELTER GEOMETRY AND METHODS OF MAKING MOLTEN GLASS - A melter apparatus includes a floor, a ceiling, and a substantially vertical wall connecting the floor and ceiling at a perimeter of the floor and ceiling, a melting zone being defined by the floor, ceiling and wall, the melting zone having a feed inlet and a molten glass outlet positioned at opposing ends of the melting zone. The melting zone includes an expanding zone beginning at the inlet and extending to an intermediate location relative to the opposing ends, and a narrowing zone extending from the intermediate location to the outlet. One or more burners, at least some of which are positioned to direct combustion products into the melting zone under a level of molten glass in the zone, are also provided. | 12-22-2011 |
| 065127000 | With gob shaping or treating subsequent to discharge through orifice | 1 |
| 20110197635 | Optimized Scoop for Improved Gob Shape - An optimized scoop for receiving the glass gobs formed by the shearing mechanism is disclosed which provides an optimal trajectory that enables glass gobs passing therethrough to have an improved glass gob shape together with a negligible increase in glass gob length, with a velocity that is equal to or better than that of previously known scoops. The optimized scoop enhances glass gob shape to produce a more uniformly cylindrical glass gobs and eliminate dog-bone configurations. Trajectory of the optimized scoop is optimized both to enhance exit velocity of the glass gobs and minimize forces applied to the glass gobs. | 08-18-2011 |
| 065128000 | With temperature modification at orifice | 5 |
| 20080314086 | Method and Device For Extracting Glass Melt From Flow Channels - A process and apparatus for removing molten glass from flow channels for the transport of production glass that are installed between a melting furnace and an extraction point for the production glass. The flow channel has a glass-resistant inner lining. A drainage unit for bottom glass is installed upstream of the extraction point for the production glass. In order to keep electrodes away from the molten glass, but still maintain a local and temporal influence on the temperature profile within the cross section, the inner lining, at least in the area of the drainage unit, of is formed of a fusion cast electrically conductive material which has a drainage opening for the bottom glass with a drainage slit above it. At least two electrodes are installed on opposite sides of the flow channel and the drainage unit for the bottom glass. The electrodes are rod-shaped and their front ends are inserted so deeply into the inner lining in the direction of the molten glass, without contact with the molten glass, so that the majority of the electric current from the electrodes passes through the molten glass to reach an electrode plate installed below the drainage opening. | 12-25-2008 |
| 20100126224 | MOBILIZING STAGNANT MOLTEN MATERIAL - A method of delivering molten material from a delivering pipe having an outlet end to a receiving vessel having an inlet end is provided. The method includes arranging the delivering pipe and the receiving vessel in such a way that a gap exists between the outlet end of the delivering pipe and the inlet end of the receiving vessel and the molten material can exit the outlet end of the delivering pipe and enter the inlet end of the receiving vessel without spilling over the inlet end of the receiving vessel. Molten material is delivered to the delivering pipe and allowed to flow from the delivering pipe into the receiving vessel. Molten material existing in the gap is heated to facilitate its flow, | 05-27-2010 |

A first electrode can be mounted to an upstream portion of the linear conduit, a second electrode can be mounted downstream of the upstream portion, and a third electrode can be mounted to a curved segment of the elbow conduit within a footprint extension of a first passage of the linear conduit. In further examples, a delivery apparatus includes an electrical circuit with a first electrode mounted to an upstream portion of a linear conduit, a second electrode mounted to a downstream portion of the linear conduit, and a third electrode mounted to an elbow conduit.

The floor includes a raised curb having width equal to final width of the inlet transition region, curb length less than the length of the inlet transition region, and curb height forming a shallowest depth portion of the fining chamber. The raised curb separates the fining chamber into the inlet transition region and a primary fining region, the primary fining region defined by the refractory floor and sidewall structure. The primary fining region has a constant depth greater than the shallowest depth but less than the depth of the inlet transition region. | 05-05-2016 |
