Abstract: The device for melting glass includes a compartment 1 for melting with a discharge throat 11 defined on top by a mobile carrier 16 having an upper part 18 extending upward above the level of glass and a lower part 17 intended to be totally immersed in the molten glass. Faces of the lower part are formed of a metal or an alloy of metals resistant to corrosion by the molten glass.

Abstract: A plurality of conduit segments contact on another which run vertically and transversely to the direction in which molten glass is channelled. Each segment includes at least one trough section and at least one cover section, an insulation of individual formed bodies, and an external casing. The segments are coupled together on support beams and may have removable insulation at joints to facilitate inspection.

Abstract: A conduit for conducting molten glass in a glass making operation comprising an elongate superstructure, an elongate carriage, a plurality of refractory blocks assembled on the carriage to form a channel for conducting molten glass, and a plurality of rollers for supporting the carriage in the superstructure and allowing the carriage to be slid out of the superstructure for servicing. The conduit further comprises clamping members extending along the sides of the conduit roof, and support members on the superstructure which can be operated transversely inwardly to cause the clamping member to engage and support the roof so that the carriage can be removed from the superstructure independently of the roof.

Abstract: A channel made from refractory elements is fabricated without gaps or expansion joints between the refractory elements by supporting the channel upon a movable carriage to accommodate the lengthwise expansion of the channel as the temperature of the channel is increased from room temperature to its operating temperature.

Abstract: An apparatus for producing a plate glass which comprises(A) a melter for storing a molten glass material,(B) a molding portion for molding the molten glass material from the melter into a plate,(C) a temperature adjusting tank located between the melter and the molding portion for maintaining the molten glass material from the melter at a uniform temperature, said temperature adjusting tank having a glass material channel for introducing the molten glass material maintained at the uniform temperature into the molding portion in a position facing on the molding portion, and(D) a tweel for adjusting a flow rate of the glass material which is raisable and lowerable in the glass material channel and has a hole through which a surface layer stream of the molten glass material can be separated and passed in the glass material channel.

Abstract: A glass melting apparatus is provided with a melting tank, a refining tank and a working tank wherein the melting tank is operatively connected to the refining tank by a temperature control connecting pipe for intermittently supplying molten glass from the melting tank to the refining tank in dependence upon the level of molten glass within the refining tank. The melting tank may be comprised of a single tank which is considerably larger than the refining tank and the working tank or may be comprised of a plurality of individual, movable tanks each of which may be brought into operative association with the refining tank for melting raw material in the melting tank, the molten glass being supplied to the refining tank and continuously treated and supplied to the working tank.

Abstract: A skimmer for use in a throat of a melting furnace. The skimmer comprises a plate having a plurality of passages therein with the passages being through the plate from a first side to a second side. Adjacent passages are in communication with each other to form a continuous passage through the plate. A first means for blocking the ends of the passages on the first side of the plate and a second means for blocking the ends of the passages on the second side of the plate are attached to the plate. A first port means is in communication with one end of the continuous passage for connecting with a cooling inlet located outside of the furnace, and a second port means is in communication with the other end of the continuous passage for connecting with a cooling outlet located outside of the furnace.

Abstract: A continuous tank-type glass melting furnace containing a bath of molten glass and having a waist section of reduced width whereat a submerged weir extends across the path of the molten glass bath flowing therethrough. The weir is located adjacent the floor of the waist section for modifying the flow path in the lower regions of the molten bath between the refining and conditioning zones of the furnace. Also, a surface barrier and stirrers may be provided in the waist section for improving the homogeneity of the molten bath.
