Abstract
Official abstract text for this publication.
A chamber ( 101, 201 ), for holding molten glass ( 113, 202 ) having a free surface ( 114, 203 ), includes a bellows ( 4, 204 ), a sealing ring ( 10, 210 ), and a cover ( 30, 50, 230 ). The bellows is coupled to the chamber, and the sealing ring is coupled to the bellows. The sealing ring may include one or more various devices, associated with operation of the chamber, including: an atmosphere supply tube ( 14, 214 ), an electric lead ( 12 ), a pressure differential sensor ( 16, 216 ), a thermo couple, an oxygen sensor, and/or an auxiliary port ( 18 ). The sealing ring further includes an upper opening ( 21 ) having an inner diameter ( 22 ). The cover is removably coupled to the sealing ring and extends over the sealing-ring-upper-opening inner diameter, wherein the sealing ring is disposed between the cover and the chamber. The cover may include various separately removable sections ( 30, 32, 34, 35, 37, 50, 52, 54 ).
