摘要： A bushing (10) including a terminal ear (100, 102) and a method of manufacturing the bushing are disclosed. The bushing includes a bushing body (11) which can include side plates (12, 14), end plates (16, 18), a bottom plate (20), and terminal ears coupled to the bushing body. Clamps (200) are attached to the terminal ears to supply electrical current to the bushing to maintain the glass inside in a liquid state. Each terminal ear includes an upper portion (110) and a lower portion (120). The upper portion is coupled to a side plate of the bushing. A clamp is attached to the lower portion of the terminal ear. The upper and lower portions are oriented at an angle with respect to each other. Support portions (130, 132, 134, 136) are provided along the side edges of the upper portions of the terminal ears. Support portions stiffen the terminal ear, thereby increasing its resistance to bending and fatigue stresses. Support portions do not contact the bushing and therefore do not directly conduct current to the bushing. Accordingly, the temperature of the support portions during operation of the bushing will be lower than the conducting portion of the terminal ears. Since the support portions operate at a lower temperature, the thermal degradation of the terminal ear is reduced.

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 bushing controller circuit for regulating the current flow through a fiber glass bushing to thereby control the temperature of the molten glass being drawn into fibers is disclosed. The bushing temperature is measured by a plurality of thermocouples which produce an average temperature reading that is used to control the power fed to the bushing. The bushing controller circuit is a three-terminal device connected across two sections of the bushing to regulate relative current flow in the two sections, in order to control the amount of fiber produced by each section. The bushing controller circuit includes a pair of timing circuits which operate in response to the polarity and magnitude of a control signal, produced at a remote control panel, to control the conductivity of a corresponding pair of current control devices connected across respective sections of the bushing. A reset circuit produces a signal corresponding to the zero crossing of the input AC power to synchronize the timing circuits.

摘要： Appareil d'atténuation de fibres de verre et procédé où du verre fondu est amené à une plaque à orifice (28) pratiquement à la pression atmosphérique afin de prévenir un écoulement de verre fondu par un orifice où l'atténuation s'est interrompue. Le mode préférentiel de réalisation du présent procédé comporte le refroidissement de la surface inférieure de la plaque à orifice (28) à une température de non mouillage et la distribution du verre fondu à la plaque à orifice (28) à une pression inférieure à la pression interne engendrée par la pression superficielle de n'importe quelle perle formée sur la surface inférieure de la plaque à orifice (28) après interruption de l'atténuation. Le mode préférentiel de réalisation du présent appareil comporte une plaque de pression perforée (105) immergée dans le corps de verre fondu et superposée sur la plaque à orifice (28) pour provoquer une chute de pression après écoulement d'atténuation normale afin de réduire la pression immédiatement au-dessus de la plaque à orifice (28) pratiquement à la pression atmosphérique ou, en tout cas, à une pression inférieure à la pression interne d'une perle formée à la suite de l'interruption de l'atténuation à l'orifice.
