摘要： Light is directed from a source through a developed and travelling motion-picture film, to pass through a reproduction lens. This light is intercepted by a tilting mirror which reflects it back through the lens where it is intercepted by a stationary mirror and reflected onto an opto-electronic receiver for conversion into signals which permit showing of the film images on a television screen.

摘要： During the ongoing course of the exposure, the aperture area increases linearly to a maximum value and then stays at the maximum value, the instantaneous amount of exposure light therefore changing correspondingly, even if the ambient-light level remains constant during the exposure. A pulse generator includes a photodetector exposed to ambient light and generates a pulse train of light-dependent repetition frequency, the pulses of which are counted by a light-totalizing counter which eventually generates a terminate-exposure signal. Ideally, the repetition frequency should increase steplessly and linearly, for maximum accuracy, or second best increase stepwise in small steps to approximate to a stepless linear increase, but in order to use an extremely low number of stepwise frequency changes, without loss of system accuracy, no attempt is made to per se keep the light-indicating repetition frequency accurate. Instead, the number and amounts of the repetition-frequency changes are so established that, when the repetition frequency is plotted against elapsed exposure time, it is proportional to a piecewise linearization of the time integral curve of the exposure-aperture surface area, the constituent straight-line segments of the linearization being confined within a predetermined error-of-total-exposure tolerance range. In the case of a linear increase of aperture size concluding in maximum size, this corresponding to a quadratic followed by a straight-line rise of the time integral of the exposure-aperture surface area, the requisite time integral curve, despite its complexity, can, for example, be implemented using as few as only three or even as few as two stepwise changes of repetition frequency, without loss of system accuracy.

摘要翻译： 在正在进行的曝光过程中，孔径面积线性增加到最大值，然后保持在最大值，因此即使在曝光期间环境光水平保持恒定，曝光光线的瞬时量也相应地改变。 脉冲发生器包括暴露于环境光的光电检测器，并产生依赖于光的重复频率的脉冲序列，其脉冲由最终产生终止曝光信号的光累计计数器进行计数。 理想情况下，为了最大的精度，重复频率应该无级地和线性地增加，或者以小的步骤逐步增加，以逼近无级线性增加，但是为了使用极低数量的逐步频率变化，而不损失系统精度 没有尝试本身保持指示重复频率的准确性。 相反，重复频率变化的数量和数量是如此确定的，当重复频率相对于经过的曝光时间绘制时，它与曝光孔表面积的时间积分曲线的分段线性化成正比，成分 线性化的直线段被限制在预定的总曝光容差范围内。 在最大尺寸结束的孔径尺寸线性增加的情况下，这对应于二次曲线，随后是曝光孔表面积的时间积分的直线上升，所需的时间积分曲线尽管复杂，但可以 例如，使用只有三个甚至仅次于两次重复频率的逐步改变来实现，而不损失系统精度。

摘要： A method for operating a sheet-forming unit of a papermaking machine. At least one fibrous material suspension is fed to a headbox and is conducted in a plurality of turbulence-generating channels to form sub-flows, and fed to a nozzle. From the nozzle, the at least one fibrous material suspension is in the form of a free jet into the forming unit to define an impingement line. In a final fluidization region of an individual turbulence-generating channel a pressure loss (Δp) of ≧50 mbar is generated within the fibrous material suspension before inlet thereof into the nozzle, and the fibrous material suspension is guided from the final fluidization region as far as the impingement line in such a way that the dwell time of the suspension in the region defined by the final fluidization region as far as the impingement line ranges from >30 ms to ≦300 ms.
