摘要： A supplemental controller (132, 144) for a fiber glass bushing (102) actively performs heating and cooling of a connected segment (104, 106, 108) of the bushing (102) which is otherwise controlled by a primary controller (122). In one embodiment, the supplemental controller (132, 144) performs heating by means of current injection into a connected bushing segment (104, 106, 108) and cooling by means of current diversion from or around the connected bushing segment (104, 106, 108). Initial start-up and balancing operations can be performed without activation of the supplemental controller (132, 144). In another embodiment of the invention, the supplemental controller (132, 144) heats a bushing segment (104, 106, 108) by injecting current in-phase with current from the primary bushing controller (122) and cools the bushing segment (104, 106, 108) by injecting current out-of-phase with current from the primary bushing controller (122).

摘要： A glass-fiber bushing (10) including a bottom tip-plate (16) and side walls (14) surrounding the bottom tip-plate (16) forming a container for molten glass. The bottom tip-plate (16) including a plurality of tips arranged to permit molten glass to flow therethrough to produce a multiplicity of individual molten glass streams from which glass fibers may be formed. The glass-fiber bushing (10) includes at least one tip-plate thermocouple (12) having a platinum tube housing (26), a pair of thermocouple wires (20, 22) transversing the tube housing (26) and terminating in a weld junction (24). The tube housing (26), thermocouple wires (20, 22) and the weld (24) are attached directly to the tip-plate (16) such that the termocouple junction (24) is formed directly at the tip-plate (16) surface.
