    • A pelvic floor muscle weight training kit includes a casing with a cap and a bottom, a set of weights, and a retaining member mounted on each of the weights. The cap has a first inside thread, and the bottom has a second inside thread. Each of the weights is different in shape and weight and is replaced in the casing individually. The retaining member has a third thread. The first and second threads of the casing are capable of being threaded with the third thread of the retaining member such that each of the weights is retained in a universal casing individually. The pelvic floor muscle weight training kit also provides for a method of testing and/or exercising pelvic floor muscles.
    • 盆底肌肉重量训练套件包括具有盖和底部的套管,一组重物和安装在每个配重上的保持构件。 盖具有第一内螺纹,底部具有第二内螺纹。 每个重物的形状和重量不同,并且在套管中单独更换。 保持构件具有第三螺纹。 壳体的第一和第二螺纹能够与保持构件的第三螺纹螺纹连接,使得每个重物分别保持在通用壳体中。 骨盆底肌肉训练套件还提供了测试和/或锻炼盆底肌肉的方法。

    • Systems and methods for enhancing the cold-formability of Ti 6-2-4-2 sheet material are described herein. Embodiments of these methods comprise cold-forming a predetermined, pretreated Ti 6-2-4-2 alloy into a cold-formed shape; subjecting the cold-formed shape to a post-forming annealing cycle comprising: heating the cold-formed shape to about 1450±25 ° F.; holding the cold-formed shape at about 1450±25° F. for about 15±2 minutes; and cooling the cold-formed shape to room temperature. Embodiments of these methods further comprise subjecting the predetermined Ti 6-2-4-2 alloy to a pre-forming annealing cycle comprising: heating the predetermined alloy to a pre-forming annealing temperature of about 1550-1750° F.; holding the predetermined alloy at the pre-forming annealing temperature for about 30 minutes; and cooling the predetermined alloy to room temperature. These methods allow components comprising 90° bend angles, having a bend factor as low as about 6.2 T, to be achieved.
    • 本文描述了用于增强Ti 6-2-4-2片材的冷成形性的系统和方法。 这些方法的实施例包括将预定的预处理的Ti 6-2-4-2合金冷成型为冷成形的形状; 将冷成形的形状进行后成型退火循环,包括:将冷成型加热至约1450±25°F; 在约1450±25°F下保持冷成形约15±2分钟; 并将冷成形体冷却至室温。 这些方法的实施例还包括使预定的Ti 6-2-4-2合金经受预成形退火循环,包括:将预定合金加热至约1550-1750°F的预成型退火温度; 将预定的合金在预成型退火温度下保持约30分钟; 并将预定合金冷却至室温。 这些方法允许实现具有弯曲因数低至约6.2T的90°弯曲角度的部件。
