Title: Method and apparatus for regulating molten glass flow into a conditioning chamber

Abstract: A predetermined rate of flow of molten glass from a reservoir, for example a glass melting furnace, is maintained by flowing glass from the reservoir to an intermediate vessel in which the glass temperature is fixed in relation to the temperature of glass discharging from the reservoir, continuously developing a control signal representing any change in the quantity of glass in the intermediate vessel, and using that signal to adjust the flow from the reservoir.
