    • An electromechanical shutter device comprising a base member and a shutter assembly comprising: an electrical current source member; a shutter member movable between a light beam blocked position and a light beam passed position; a light beam blocking member associated with the shutter member; a shutter coil associated with the shutter member which generates an electromagnetic force when energized; at least one magnet which generates a magnet flux directed towards and intersecting the shutter coil; electrically conductive means connecting the electrical current source member to the shutter member for passing electrical current to energize the shutter coil and to control movement of the shutter member between the light beam blocked and passed positions; wherein when the shutter coil is energized, an electromagnetic force is generated that interacts with the magnetic flux to thereby cause movement of the shutter member between the light beam blocked and light beam passed positions.

    • A flexible coupling shaft which is suitable for plug-in installation between the splined output shaft of a turbine engine and the splined input shaft of a testing apparatus for the production test of the engine, includes a shaft member having opposed end flanges which are connected by: (1) bayonet connections to hub members, each having a splined central portion for receiving the splined shaft of either the engine or the testing device; and (2) flexible joint connections in the form of stacked arrays of flat metallic shims, with the stacked shims being separately connected respectively to the flange parts of the shaft and the associated hub. By this arrangement, axial misalignment between the splined input and output shafts is compensated by the splined interconnections, while lateral misalignments are compensated for by bending of the stacked shims which define a diaphragm-type coupling. Upon removal of either the engine shaft or the shaft of the testing apparatus, the respective bayonet connection supports the cantilevered shaft member of the flexible coupling apparatus, thereby precluding overstressing of the stacked shims.
    • 适用于涡轮发动机的花键输出轴与用于发动机生产试验的试验装置的花键输入轴之间的插入式安装的柔性联轴器包括具有相对的端部凸缘的轴构件, (1)卡口连接到轮毂构件,每个都具有用于接收发动机或测试装置的花键轴的花键中心部分; 和(2)以扁平金属垫片的堆叠阵列的形式的柔性接头连接,其中堆叠的垫片分别分别连接到轴的凸缘部分和相关联的毂。 通过这种布置,花键输入轴和输出轴之间的轴向未对准由花键互连补偿,而横向不对准通过限定隔膜式联接器的堆叠垫片的弯曲来补偿。 在移除发动机轴或测试装置的轴时,相应的卡口连接支撑柔性联接装置的悬臂轴构件,从而防止堆叠垫片的过度应力。
