Molten glass metering device for making lamp bases |
摘要 |
A molten glass metering device for making electric lamp bases by accurately metering the rate of flow of molten glass from an orifice in the wall of a glass melting furnace. The device comprises a metal member including an integral hollow elongated member aligned with the orifice. The flow of glass is controlled by varying the flow of electrical current through the metal member to control the temperature of same and to control the temperature of the glass within the metal member, thereby to control the rate of flow of molten glass therethrough.
