    • A measuring instrument is described for measuring inclination or acceleration. For inclination only three strings are required. For acceleration four strings are required. The instrument comprises a mass (38) suspended by three or four stretched strings (32, 34, 36 or 70, 72, 74 and 76) with the strings being suspended from terminals within a frame (10). The strings are conductive as is also the mass (38) and a flexible electrical connection (46) allows connection to be made to the star point of the three or four conductive strings. The strings form the frequency determining elements in the outputs of negative resistance amplifiers (50, 52, 54 etc.,) and differential amplifiers (56, 58, 60) together with decoding circuits (62) provide output signals for a computing device (64) which inturn provides data for an indicator (66) to indicate the inclination of the frame (10) relative to some datum. Calibrating means (68) is provided for calibrating the read-out device (66). Where four strings are employed (see Fig. 2) a further display device (94) may be provided to indicate the magnitude of the accelerating force, the first display device (66) indicating the direction in which the accelerating force is acting. In one embodiment a generally triangular mass (108) is cut away on it's underside to allow it to rest on three limbs (120, 122, 124) of a spider having an integral central webb (188) which is secured to the triangular weight (108). The limbs of the spider are secured at their ends to mounting blocks one of which is resiliently biased in an outward direction to tension the spider. The underside of the triangular mass (108) is formed with protrusions (154) for engaging in locating channels (156) formed in the base of a retaining housing (100).
    • 描述了用于测量倾斜度或加速度的测量仪器。 为了倾斜,只需要三根绳子。 为了加速,需要四个字符串。 仪器包括由三个或四个拉伸的绳索(32,34,36或70,72,74和76)悬挂的质量块(38),其中绳索悬挂在框架(10)内的端子上。 弦也是质量(38)导电的,并且柔性电连接(46)允许连接到三个或四个导电串的星形点。 串形成负电阻放大器(50,52,54等)的输出中的频率确定元件和差分放大器(56,58,60)以及解码电路(62)提供用于计算设备(64)的输出信号 ),其向内指示器(66)提供用于指示相对于某些数据的框架(10)的倾斜度的数据。 校准装置(68)用于校准读出装置(66)。 在采用四个串的情况下,可以提供另外的显示装置(94)来指示加速力的大小,第一显示装置(66)指示加速力作用的方向。 在一个实施例中,大致三角形的质量块(108)在其下侧被切掉,以使其能够搁置在具有整体中央腹板(188)的三角形(120,122,124)上,该中心腹板被固定到三角形重量 108)。 蜘蛛的四肢固定在其安装块上,其中一个被弹性偏压向一个向上的方向张紧蜘蛛。 三角形物体(108)的下侧形成有用于接合形成在保持壳体(100)的基部中的定位通道(156)的突起(154)。
