摘要： An improved adhesive is disclosed for the automated assembly and alignment of kinescopes and yokes. The adhesive consists of a polymer matrix and a filler. The polymer matrix comprises an isocyanate component, a polyol component comprising one or more polyols having an average functionality greater than 2.0 and an average hydroxyl equivalent of from about 2000 to about 2500, a chain extender, a suitable catalyst and, optionally, other ingredients such as an antioxidant. The inorganic or organic filler comprises from about 32 to about 60 percent by volume of the adhesive. The subject adhesive is blended into a slow-curing and a fast-curing formulation, which are applied to a portion of the gap between the kinescope and the yoke. The fast-curing adhesive allows the completed assembly to be rapidly withdrawn from the assembly apparatus, or robot, and maintains the alignment during curing of the slower-curing adhesive. When both compositions are fully cured, there is produced an excellent, durable bond.
摘要翻译：公开了改进的粘合剂用于显像管和轭的自动组装和对准。粘合剂由聚合物基质和填料组成。聚合物基质包含异氰酸酯组分，多元醇组分，其包含平均官能度大于2.0且平均羟基当量为约2000至约2500的一种或多种多元醇，扩链剂，合适的催化剂和任选的其它成分作为抗氧化剂。无机或有机填料占粘合剂的约32至约60体积％。主题粘合剂被混合到慢固化和快速固化制剂中，其被施加到显像管和轭之间的间隙的一部分。快速固化粘合剂允许完成的组件从组装设备或机器人中快速抽出，并且在固化较慢固化的粘合剂期间保持对准。当两种组合物完全固化时，产生优异的耐用粘结。

摘要： An epoxy composition derived from tetraglycidated methylene dianiline cured with a methylated maleic acid adduct of phthalic anhydride has a high glass-transition temperature and a low curing temperature and when cured has very high bond strength. This epoxy can be used to bond a diamond cutterhead stylus to a piezoelectric element.
摘要翻译：由邻苯二甲酸酐的甲基化马来酸加合物固化的四亚甲基二亚胺二苯胺衍生的环氧组合物具有高玻璃化转变温度和低固化温度，并且当固化时粘结强度非常高。该环氧树脂可用于将金刚石切割刀触针焊接到压电元件。
