    摘要： A defective focusing coil, impregnated with and held in place with epoxy is removed from its inner lead liner and its outer brass housing by immersing the assembled parts in a bath of liquid nitrogen until the temperature of the assembly is reduced to the temperature of the liquid nitrogen, about -350.degree. F. The assembly is then removed from the bath and a series of sharp blows are then directed to the side of the brass housing to break the bond between the super cooled epoxy and the housing. Axial pressure is then applied to the coil, to remove the coil and liner. The coil is then cut longitudinally into two half cylinders, whereupon the coil is split from the liner, all without injury to either the liner or the housings.

    摘要翻译： 通过将组装好的部件浸入液氮浴中，从其内部引线衬套及其外部黄铜壳体中去除浸渍并固定在环氧树脂上的缺陷聚焦线圈，直到组件的温度降低到液体的温度 氮气，约-350华氏度。然后将组件从浴中取出，然后一系列尖锐的吹风被引导到黄铜外壳的侧面，以破坏超级冷却的环氧树脂和壳体之间的结合。 然后将轴向压力施加到线圈，以去除线圈和衬垫。 然后将线圈纵向切割成两个半圆柱体，然后线圈从衬套分离，所有这些都不会损伤衬套或壳体。
