    摘要： Continuous filament apex fittings and methods of manufacture thereof to provide high-strength, low-weight fittings for use on cargo lifts and the like, and as replacements for metal clevises. The fittings are made by wet-winding one or more strands of continuous filaments into a loop, forming the loop into a basic clevis-like shape and curing the resin. The use of a flexible resin allows spreading of the clevis eyes for entry and removal of the item to be retained by the clevis without a separate clevis pin. Twisting of the loop one or more times along the major length of the loop prior to bending in the basic clevis shape creates an integrated clevis body having better load distribution across the cross-section thereof. Alternate methods of manufacture are disclosed.

    摘要翻译： 连续长丝三角配件及其制造方法，以提供用于货物升降机等的高强度，低重量的配件，以及用作金属托架的替代物。 配件通过将一根或多股连续长丝卷绕成环而制成，将环形成基本的U形夹状并固化树脂。 使用柔性树脂可以扩展U形夹眼以进入和移除由U形夹保持的物品，而不需要单独的U形销。 在基本的U形夹形状弯曲之前，沿着环的主长度将环路扭转一次或多次，形成了整体的U形夹体，其在横截面上具有更好的载荷分布。 公开了替代的制造方法。

    摘要： A high-strength, low weight, electromechanical cable is manufactured from aromatic polyamide multifilament yarns impregnated with a hydrolytically stable polyurethane resin to form a protective coating. The coating provides load adjustment from fiber to fiber, eliminates abrasive self-destruction of the fibers during flexing of the yarn under load, protects the fiber to some extent from ultraviolet radiation, aggressive chemicals or abrasive particles and makes it possible to preform the yarn. The coating comprises a reaction product of a liquid tetramethylene glycol, an aliphatic/cycloaliphatic diisocyanate and a diamine coupling-curing agent. The impregnated yarns are dried, twisted together, heated above the softening point of the resin to fuse the coatings of adjacent yarns, and then cooled to form a set twisted helix of the yarns.
