    • A bushing including a terminal ear and a method of manufacturing the bushing are disclosed. The bushing includes a bushing body which can include side plates, end plates, a bottom plate, and terminal ears coupled to the bushing body. Clamps 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 and a lower portion. 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 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.
    • 公开了一种包括端子耳套和制造套管的方法。 衬套包括衬套主体,其可以包括侧板,端板,底板和联接到衬套主体的端子耳。 夹子连接到终端耳朵以向套管提供电流以将玻璃内部保持在液体状态。 每个终端耳朵包括上部和下部。 上部联接到衬套的侧板。 夹具附接到终端耳的下部。 上部和下部相对于彼此以一定角度定向。 支撑部沿着终端耳的上部的侧边缘设置。 支撑部分使终端耳朵变硬,从而增加其对弯曲和疲劳应力的抵抗力。 支撑部分不接触套管,因此不直接将电流传导到衬套。 因此,衬套操作期间的支撑部分的温度将低于终端耳的导电部分。 由于支撑部分在较低的温度下操作,所以终端耳的热劣化减小。

    • A screen comprises an electrically conductive elongate inner screen plate. The inner screen plate has at least one elongate fold therein and at least two elongate divergent surfaces on opposing sides of the fold. Each divergent surface has an upper end and opposing edges tapering downward from the upper end. The upper ends of the divergent surfaces diverge from one another. Each of the divergent surfaces has a plurality of holes therein. The screen further comprises at least two electrically conductive outer screen plates. The outer screen plates are attached to the edges of the divergent surfaces and extend between the divergent surfaces. Each of the outer screen plates has a plurality of holes therein. Another embodiment of the invention is directed toward a glass fiber bushing system comprising a bushing body and a screen within the bushing body. The bushing body has opposing end plates. The screen comprises opposing ends. Each of the ends has an upper portion and a lower portion. The upper portion of each of the ends is attached to one of the end plates. The lower portion of each of the ends is spaced apart from the end plates.
    • 屏幕包括导电细长内屏板。 内筛板在其中具有至少一个细长折痕和在折叠的相对侧上的至少两个细长的发散表面。 每个发散表面具有从上端向下逐渐变细的上端和相对的边缘。 发散表面的上端彼此分开。 每个发散表面上都有多个孔。 屏幕还包括至少两个导电外屏板。 外屏板连接到发散表面的边缘并在发散表面之间延伸。 每个外筛板在其中具有多个孔。 本发明的另一实施例涉及一种玻璃纤维衬套系统,其包括衬套主体和衬套主体内的屏幕。 衬套主体具有相对的端板。 屏幕包括相对的端部。 每个端部具有上部和下部。 每个端部的上部附接到一个端板。 每个端部的下部与端板间隔开。

    • Improved construction for bushings used to produce glass fibers is provided. Such bushings commonly have thin side and end walls of precious metal defining a glass-melting chamber, with a bottom in which fiber-forming tips are located. Refractory material is located around the side and end walls. When the bushings are heated to operating temperatures, the metal walls tend to expand more than the refractory material and, particularly with larger bushings, the walls can buckle and crack since full expansion of the walls is prevented by the refractory material. To overcome this, it has been found that the bushings can be constructed with space between the metal walls and the refractory, with the space equalling the difference in expansion of the two materials. The space is formed by layers of heat-removable material, such as wax which melts out as the bushings are heated. When the bushings are at operating temperature then, the metal walls expand into the space and come into contact with the surrounding refractory material.
    • 提供了用于生产玻璃纤维的衬套的改进结构。 这种衬套通常具有限定玻璃熔化室的贵金属的薄侧壁和端壁,其中形成有纤维形成尖端的底部。 耐火材料位于侧壁和端壁周围。 当衬套被加热到工作温度时,金属壁倾向于比耐火材料膨胀,特别是对于较大的衬套,壁可以弯曲和破裂,因为通过耐火材料防止了壁的充分膨胀。 为了克服这个原因,已经发现,衬套可以在金属壁和耐火材料之间形成空间,空间等于两种材料的膨胀差。 空间由可热去除的材料层形成,例如当衬套被加热时熔化的蜡。 当衬套处于工作温度时,金属壁膨胀到空间中并与周围的耐火材料接触。
