摘要： In flat glass manufacture on a molten metal bath, there is forward flow of molten metal entrained by accelerating glass over an upstream return flow of cooler molten metal which is received in a deepened region of the bath. Upstream molten metal flows are drawn from that deepened region to replenish the molten metal entrained by the accelerating ribbon.

摘要： Linear induction motors are mounted above the bath of molten metal employed in the production of a float glass ribbon to direct dross from the surface of the metal into dedrossing motors are suspended from a retracting mechanism mounted on the upper external bath structure so that they can be quickly raised from their operative position when desired, thus permitting unhindered access therebeneath to the side areas of the bath.

摘要： A method for forming flat glass of high optical quality on a bath of molten tin, in which the glass has a relatively short residence time, is disclosed. The method involves adding an oxidizing agent to the hotter regions of the molten tin bath which is believed to modify the bottom or tin-contacting surface of the glass while the glass is on the bath of molten tin so as to be able to produce glass substantially free of top surface distortion, a problem which is particularly severe for glass having relatively short residence times on molten tin.

摘要： The bottom of a float chamber of a glassmaking apparatus of the type used for manufacturing flat glass is provided with generally inverted ''''T''''-shaped grooves for receiving dam barrier sections each having a generally inverted ''''T''''-shaped, cross-sectional configuration. Dam barrier sections are positioned in one of the grooves to form a dam barrier to provide discrete compartments of molten metal in the float chamber.

摘要： 1. In the method of manufacturing a continuous sheet of glass comprising the steps of delivering a stream of molten glass onto a pool of molten metal, conveying the glass along the surface of said pool of molten metal, cooling said glass to form a dimensionally stable continuous sheet of glass and withdrawing said continuous sheet of glass from said pool of molten metal whereby the bottom surface of said sheet of glass is characterized by non-homogenous defects, the improvement comprising (a) discharging said stream of molten glass across a support such that said stream of molten glass has an upper, exposed surface and a lower surface in contact with said support; (b) separating said stream of molten glass on said support into two portions, the first portion including glass in contact with said support and the second portion including glass constituting said exposed surface; (c) removing said first portion of molten glass; and (d) delivering said second portion of molten glass onto said pool of molten metal, whereby a continuous sheet of glass is formed having a bottom surface characterized as being substantially defect-free.

摘要： The method disclosed pertains to making glass sheets by placing molten glass on a molten metal bath in a channel which communicates with chambers on the sides of the channel which allows molten metal to flow from the chambers. The temperature of the molten glass is regulated within adjustable blocks on the sides of the channel.

摘要： In the float process for the manufacture of flat glass in ribbon form on a bath of molten metal, the movement of the ribbon along the bath surface creates a forward flow of molten metal in a surface layer of the bath, which forward flow is segregated by flow dividing means for an upstream return flow of cooler molten metal along the bottom of the bath.

摘要： The temperature of the molten metal of the bath, in the float process for flat glass manufacture, is regulated by means of thermally conductive fins, e.g. of carbon, inset into the floor of the tank structure and in direct thermal contact with the molten metal of the bath. The outer end of each fin is cooled to give localised heat extraction from the molten metal.
