    摘要： An adapter and method for through the lens (TTL) laser range sensor probes enables use of a TTL probe of a given exit pupil size to be used with a shared objective lens requiring a entrance pupil size, as entered from the laser range sensor, that is different from the TTL probe exit pupil size. Embodiments of the adapter include optics, such as a first lens and a resolving second lens that expand or contract the TTL laser radiation depending on whether the first lens is a diverging, a negative focal length lens, or a converging, positive focal length lens, and the second lens is converging or diverging, respectively, in a Galilean arrangement. Embodiments also provide a Keplerian arrangement, can function with non-collimated radiation, and can include mirrors to yield a more compact adapter. Additional embodiments include at least one adjustable lens element between the first and second lenses, the at least one adjustable lens element being connected to an actuator for movement along the optical path. The adapter can be arranged in a folded configuration in which mirrors are used to form a more compact adapter.

    摘要翻译： 用于通过透镜（TTL）激光范围传感器探针的适配器和方法使得能够使用给定出射光瞳尺寸的TTL探头与需要从激光范围传感器输入的入射光瞳尺寸的共享物镜一起使用， 与TTL探头出口光瞳尺寸不同。 适配器的实施例包括根据第一透镜是发散的，负焦距透镜或会聚正焦距透镜来扩展或收缩TTL激光辐射的诸如第一透镜和分辨率第二透镜的光学器件， 并且第二透镜分别在伽利略布置中会聚或发散。 实施例还提供开普勒装置，可以与非准直辐射一起工作，并且可以包括镜子以产生更紧凑的适配器。 另外的实施例包括在第一和第二透镜之间的至少一个可调透镜元件，所述至少一个可调透镜元件连接到致动器以沿着光路移动。 适配器可以布置成折叠配置，其中使用反射镜形成更紧凑的适配器。

    摘要： An orthopedic screw having a torque driving head with a rounded side a spherical wall for multiaxial use, a self starting, self tapping insertion tip and a threaded portion including a cancellous thread. The threaded portion has a major diameter defined by a spiraling thread and a minor diameter. The head is joined to the threaded portion by an area of from about 2 to about 6 turns of the thread along the longitudinal axis in which the minor diameter tapers by an angle of from about 4 to about 12° and the major diameter of the screw remaining substantially the same meaning that the major diameter is constant to about +/−0.05 mm along the length of the threaded portion. The screw includes a multilobe torque driving recess joined to a cylindrical recess. In a further embodiment, the screw has an insertion tip which is forms a portion of a sphere.

    摘要： A gate valve comprises a valve body having an internal working fluid passage and an internal gate chamber extending transverse to the working fluid passage. In addition, the gate valve comprises a gate disposed in the internal gate chamber and movable within the gate chamber between a closed position obstructing fluid flow through the working fluid passage and an open position allowing fluid flow through the working fluid passage. Further, the gate valve comprises an internal sealing arrangement coaxially disposed in the working fluid passage and extending between the valve body and the gate to form a barrier between the internal working fluid passage and the gate chamber. The internal sealing arrangement includes a frustoconical metal sealing surface adapted to sealingly engage an opposed mating frustoconical metal sealing surface on the valve body to form a first tapered metal-to-metal seal between the sealing arrangement and the valve body.
