    • An ear covering is produced by sewing first and second cloth layers together along a first closed loop seam, and forming a hole inside the loop and extending through both layers; turning the sewn first and second layers inside out by passing one layer through the opening; then passing one of the layers through a passage in a flexible insert in the form of a distorted, truncated cone; placing a third cloth layer over one of the first and second layers and sewing the first second and third cloth layers along a second closed-loop seam, thereby enclosing the insert within a toroidal enclosure formed by portions of the first and second layers. Afterwards, the assembly is turned inside out to form a cup-shaped receptacle for receiving an external ear, with the second seam in the interior of the receptacle, and with the first seam within the toroidal enclosure.
    • 通过将第一和第二布层沿着第一闭环接缝缝合在一起,并在环内形成一个孔并延伸穿过两个层来产生耳罩。 通过将一层通过开口将缝合的第一层和第二层内侧翻开; 然后使其中的一层穿过柔性插入件中的通道,其形式为扭曲的截头锥体; 将第三布层放置在第一层和第二层之一上,并沿着第二闭环接缝缝合第一第二和第三布层,从而将插入件封闭在由第一层和第二层的部分形成的环形外壳内。 之后,将组件向内转出,形成用于容纳外耳的杯状容器,其中第二接缝位于容器内部,并且第一接缝在环形外壳内。

    • In a chain tensioner comprising a plunger having toothed racks engageable with wedge-shaped cams which cooperate with oblique cam-guiding surfaces, the cam-guiding surfaces are formed on a cam-receiving ring disposed in an enlarged part of the cam-receiving hole adjacent the front end of the tensioner housing, and axially movable, through a limited distance, in a space between a shoulder and a seal cap. The axially movable cam-receiving ring increases both the minimum and maximum backlash distances of the plunger, thereby making it possible for the tensioner to accommodate different chain conditions by changing the axial dimensions of the cam-receiving ring, or the space in which it moves, instead of, or in addition to, modifying the angle of the cam-guiding surfaces.
    • 在具有可与楔形凸轮啮合的齿形齿条的活塞的链条张紧器中,所述楔形凸轮与倾斜凸轮引导表面配合,凸轮引导表面形成在凸轮接收环上,所述凸轮接收环设置在相邻的凸轮接收孔的扩大部分中 张紧器壳体的前端,并且在肩部和密封帽之间的空间中可轴向移动,限制距离。 轴向可移动的凸轮接收环增加柱塞的最小和最大间隙距离,从而使得张紧器可以通过改变凸轮接收环的轴向尺寸或其移动的空间来适应不同的链条条件 ,而不是或改变凸轮引导表面的角度。
