    • A novel automatic test measuring apparatus of the pendulum variety for readily and easily determining film and the like hardness is adapted to automate all the operations necessarily preceding the commencement of a measurement stage using, in connection therewith, a recording unit or printer to supply the operator with the numerical results of all the measurements without personal manipulation(s). In making a measurement, the necessary time count for passing from amplitude .alpha. to amplitude .beta. is effected by means of a photo-electric cell. This records the passage of a pendulum arm having a predetermined period during the time that the oscillation amplitude is higher than .beta.. The involved count gives the measured time necessary for the measurement. The automatic apparatus advantageously reduces error relating to each measurement and increases the number of measurements to be effected on one and the same test film to yield a vastly more reliable mean statistical value. Provision may be made to simultaneously test several films, either by simultaneous of successive mountings of a plurality of films whose hardness is being measured.
    • 一种用于容易且容易地确定膜等硬度的摆式品种的新型自动测试测量装置适于自动化在测量阶段开始之前必须进行的所有操作,使用与此相关联的记录单元或打印机来供应操作者 具有所有测量的数值结果,无需个人操作。 在进行测量时,通过光电池实现从幅度α到幅度β的必要时间计数。 这记录了在振荡幅度高于β的时间内具有预定周期的摆臂的通过。 所涉及的计数给出测量所需的测量时间。 自动装置有利地减少了与每个测量相关的误差,并增加了在同一测试胶片上进行的测量次数,以产生更可靠的平均统计值。 可以提供同时测试多个膜,无论是通过连续安装多个正在测量硬度的膜的膜。
