    • An expansion joint is shown for use in joining adjacent concrete sections separated by an expansion slot such as in a roadway having concrete sections and a slot therebetween. The joint includes a preformed longitudinal sealing element which is formed of a resilient material and installed within the slot. An initially flowable adhesive material is applied between the sealing element and opposing side surfaces of the concrete sections making up the joint. The moduli of elasticity of the adhesive material and sealing element are selected so that forces exerted upon the joint by expansion and contraction of the concrete sections result in movement of the central sealing element, rather than exerting strain upon the adhesive bond.
    • 示出了用于连接由膨胀槽分开的相邻混凝土部分的膨胀接头,例如在具有混凝土部分的道路和其间的狭槽中。 接头包括由弹性材料形成并安装在槽内的预成型纵向密封元件。 在密封元件和构成接头的混凝土部分的相对的侧表面之间施加初始可流动的粘合材料。 选择粘合剂材料和密封元件的弹性模量,使得通过混凝土部分的膨胀和收缩施加在接头上的力导致中心密封元件的移动,而不是在粘合剂粘合上施加应力。

    • An exercise putty kit for providing manipulative physical therapy of increasing difficulty comprises a container (12) of a large mass (14) of borosiloxane putty and a package (16) of borosiloxane or siloxane putty. At least one small mass (18-32) is provided to the patient along with the large mass (14), the small mass and large mass being manipulated by the patient until a uniform color and stiffness are achieved in the combined mass (38). Preferably, a plurality of small masses (18-32) having a variety of colors are available for successive manipulation with the combined mass (38). The kit provides a means by which the difficulty of manipulative physical therapy may be monitored and increased. As more small masses (18-32) are added to the combined mass (38), the stiffness increases, requiring more manipulation to fully blend the masses.
    • 用于提供难度增加的操作性物理治疗的运动油灰盒包括大量(14)硼硅氧烷油灰的容器(12)和硼硅氧烷或硅氧烷油灰的包装(16)。 至少一个小质量(18-32)与大质量(14)一起提供给患者,小质量和大质量被患者操纵,直到在组合的质量(38)中实现均匀的颜色和刚度, 。 优选地,具有各种颜色的多个小质量块(18-32)可用于组合质量块(38)的连续操作。 该试剂盒提供了可以监测和增加操纵性物理治疗难度的方法。 随着更多的小质量(18-32)被添加到组合质量(38)中,刚度增加,需要更多的操纵来完全混合质量。
