    • A gauge for measuring the magnitude of a measurable quantity, such as fluid pressure. The gauge includes a rotatable axle or shaft intended to rotate in response to different magnitudes of the quantity being measured and includes a dial possessing indicia corresponding to different magnitudes of such quantity. The improvement in the gauge relates to a very light weight pointer having a needle section and a counterbalance section, in which the needle section is formed of a relatively light mass material, preferably balsa wood. The counterbalance section may be fashioned of a different, denser material. The surface of the counterbalance section may be provided with a series of parallel depressions that aid in cutting or trimming the counterbalance section to achieve a balance of the pointer about the axle or shaft. A method of making such a pointer is also disclosed.
    • 用于测量可测量的量值的量规,例如流体压力。 该计量器包括可响应于被测量的不同量值旋转的可旋转轴或轴,并且包括具有对应于该量的不同大小的标记的表盘。 该量规的改进涉及一种具有针部分和平衡部分的非常轻的指示器,其中针部分由较轻质量的材料形成,优选为轻木。 平衡部分可以由不同的,更致密的材料制成。 平衡部分的表面可以设置有一系列平行的凹陷,其有助于切割或修剪平衡部分,以实现指针围绕轴或轴的平衡。 还公开了制造这种指针的方法。

    • An apparatus for measuring a physical quantity or parameter includes a housing having a supportably mounted shaft member. A first end of the shaft member is placed in proximity with the output of a displacement device which is responsive to a change in the physical quantity. A ribbon spring member is coaxially disposed and wound helically about the supported shaft member, one end of the spring member being attached to the shaft and a remaining end to a supporting structure. Based on a change in the physical quantity, (pressure, velocity, temperature, etc.), the output of the displacement device engages the shaft member, which axially displaces and rotates due to the constraint of the ribbon spring member. The rotation of the shaft member produces a corresponding angular deflection of an attached pointer relative to readable indicia.
    • 用于测量物理量或参数的装置包括具有可支撑地安装的轴构件的壳体。 轴构件的第一端放置在与物理量的变化相应的位移装置的输出附近。 带状弹簧构件同轴地设置并围绕支撑的轴构件螺旋地缠绕,弹簧构件的一端附接到轴,而剩余的端部附接到支撑结构。 基于物理量(压力,速度,温度等)的变化,位移装置的输出与轴构件接合,该轴构件由于带状弹簧构件的约束而轴向移位和旋转。 轴构件的旋转相对于可读标记产生附接指针的相应角度偏转。
