摘要： An end effector device (A) for grasping and holding an article such as a handle (18) of a space telescope is disclosed. The device includes a V-shaped capture window (74) defined as inclined surfaces (76, 78) in parallel face plates (22, 24) which converge toward a retainer recess (54) in which the handle is retained. A pivotal finger (30) meshes with a pair of pivoted fingers (26, 28) which rotate in counterrotation. The fingers rotate to pull a handle within the capture window into recess (54) where latches (50) lock handle (18) in the recess. To align the capture window, plates (22, 24) may be cocked plus or minus five degrees on base (64).

摘要： An apparatus for testing and evaluating the spray pattern of high pressure fuel injector elements for use in supplying fuel to combustion engines. Prior art fuel injector elements were normally tested by use of low pressure apparatuses which did not provide a purge to prevent mist from obscuring the injector element or to prevent frosting of the view windows; could utilize only one fluid during each test; and had their viewing ports positioned one hundred eighty (180.degree.) apart, thus preventing optimum use of laser diagnostics. The high pressure fluid injector test apparatus includes an upper hub, an upper weldment or housing, a first clamp and stud/nut assembly for securing the upper hub to the upper weldment, a standoff assembly within the upper weldment, a pair of window housings having view glasses within the upper weldment, an injector block assembly and purge plate within the upper weldment for holding an injector element to be tested and evaluated, a lower weldment or housing, a second clamp and stud/nut assembly for securing the lower weldment to the upper weldment, a lower hub, a third clamp and stud/nut assembly for securing the lower hub to the lower weldment, mechanisms for introducing fluid under high pressure for testing an injector element, and mechanisms for purging the apparatus to prevent frosting of view glasses within the window housings and to permit unobstructed viewing of the injector element.
摘要翻译： 一种用于测试和评估用于向燃烧发动机供应燃料的高压燃料喷射器元件的喷射模式的装置。 现有技术的燃料喷射器元件通常通过使用不提供吹扫以防止雾遮挡喷射器元件或防止视窗结霜的低压设备来测试; 每次测试中只能使用一种流体; 并且它们的观察端口位于距离180°（180°）的位置，从而防止最佳地使用激光诊断。 高压流体注射器测试装置包括上部轮毂，上部焊件或壳体，用于将上部轮毂固定到上部焊件的第一夹具和螺栓/螺母组件，上部焊件内的支座组件，一对窗口壳体， 在上部焊件内观察玻璃，在上部焊件内的用于保持要测试和评估的注射器元件的喷射器组件和吹扫板，下部焊件或壳体，第二夹具和螺柱/螺母组件，用于将下部焊件固定到 上部焊接件，下部轮毂，第三夹具和用于将下部轮毂固定到下部焊件的螺柱/螺母组件，用于在高压下引入流体以测试喷射器元件的机构，以及用于清洁设备以防止观察眼镜结霜的机构 在窗户外壳内，并且能够不间断地观察注射器元件。

摘要： A knee brace for aiding in rehabilitation of damaged leg muscles includes upper and lower housings normally pivotable one relative to the other about the knee joint axis of a patient. The upper housing is attachable to the thigh of the patient above the knee joint while the lower housing is secured to a stirrup which extends downwardly along the patient's leg and is attached to the patient's shoe. An actuation rod is carried within the lower housing and is coupled to a cable. The upper and lower housings carry cooperative clutch/brake elements which normally are disengaged to permit relative movement between the upper and lower housings. When the cable is extended the clutch/brake elements engage and lock the housings together. A heel strike mechanism fastened to the stirrup and the heel of the shoe is connected to the cable to selectively extend the cable and lock the brace in substantially any position when the patient places weight on the heel.
