    • In a cylindrical mirror analyzer, charged, particles from a source are deflected in the radial electric field between a pair of coaxial tubular electrodes, and are brought to a focus. A collector aperture positioned at the focus selects particles of predetermined energy, these particles being detected by a suitable detector. The particles cross the axis at some point between the source and the focus. An apertured member located at this point prevents skew electrons (i.e. electrons not travelling in radial planes) from reaching the focus. In this way the performance of the analyzer is improved.
    • 在圆柱形镜面分析仪中,来自源的带电粒子在一对同轴管状电极之间的径向电场中偏转,并被聚焦。 位于焦点处的收集器孔选择预定能量的颗粒,这些颗粒由合适的检测器检测。 颗粒在源和焦点之间的某个点处穿过轴。 位于该点的有孔构件防止偏斜电子(即,不在径向平面中行进的电子)到达焦点。 以这种方式,提高了分析仪的性能。

    • A specimen stage for an electron microscope having a wire-driven gimbal assembly. The assembly is so designed that there is no interaction between the tilting of the inner and outer gimbals. The drive for the gimbals comprises two wires, each of which is attached at one end to a drive pulley and at its outer end, after passing around a guide pulley pivoted about the outer gimbal axis, is coupled to the inner gimbal. Thus, when the outer gimbal is tilted, the wires wind on to or off of the guide pulleys, causing the drive pulley to move towards or away from the gimbals, but with substantially no tilting of the inner gimbal.
    • 具有线驱动万向节组件的电子显微镜的标本台。 该组件的设计使得内部和外部万向架的倾斜之间没有相互作用。 用于万向架的驱动器包括两条导线,每条线一端连接到驱动皮带轮,并且在其外端在围绕围绕外平衡杆轴线枢转的引导滑轮穿过外部端部之后连接到内部万向节。 因此,当外部万向架倾斜时,导线卷绕到导向滑轮上或从导向滑轮上移开,导致驱动滑轮朝向或远离万向面移动,但是基本上没有内部万向架的倾斜。

    • This invention relates to protective relays for systems with transformer loading, either power transformers or transmission lines with transformer feed-offs. In such systems, transformer inrush currents may cause relay tripping on initial energization. To prevent this false tripping, inrush currents may be detected and tripping inhibited. By the invention, inrush currents are detected by squaring the monitored quantity at the trip level, and determining whether the resulting rectangular pulses are separated from each other by more than a present amount. Inrush currents give peaky waveforms, with wide gaps between pulses, while genuine fault currents are roughly sinusiodal, and give wide pulses with only narrow gaps.
    • 本发明涉及用于具有变压器负载的系统的保护继电器,电力变压器或具有变压器馈电的传输线。 在这种系统中,变压器浪涌电流可能会在初始通电时引起继电器跳闸。 为了防止这种错误跳闸,可以检测浪涌电流并禁止跳闸。 通过本发明,通过在跳闸级别平均监视量来检测浪涌电流,并且确定所得到的矩形脉冲是否彼此分离超过当前量。 浪涌电流产生峰值波形,脉冲之间具有较大的间隙,而真正的故障电流大致为正弦波,并且仅产生较窄的间隙的宽脉冲。
