摘要： A device (10) for composing graphics comprising a flash lamp (19) for irradiating portions of strip material (12) through a template (22) when an arm (24) supporting the lamp (19) is moved to an exposure position at an exposure station (14). The template (22) has a rectangular array of windows (20) and is manually positionable on locating pins (23) at the exposure station (14) for different exposures. A positive image (33) of each window (20) is provided on the template (22), and the locating pins (23) are movable via movement of the lamp arm (24) from a preview position where the image (33) is at the exposure station (14) so the operator can see where the graphic will be formed, to an exposure position with the associated window (20) located at the exposure station (14) for exposure.
摘要翻译：一种用于组成图形的装置（10），包括闪光灯（19），用于当支撑灯（19）的臂（24）移动到曝光位置时，通过模板（22）照射条形材料（12）的部分曝光台（14）。模板（22）具有矩形的窗口阵列（20），并且可手动定位在曝光站（14）处的定位销（23）上，用于不同的曝光。每个窗口（20）的正像（33）设置在模板（22）上，定位销（23）可通过灯臂（24）从图像（33）所在的预览位置的移动而移动在曝光站（14）处，使得操作者可以看到图形将被形成到曝光位置，其中相关的窗口（20）位于曝光站（14）处以进行曝光。

摘要： n assembly for use in an analog audio record/ playback or playback system to achieve and maintain the same phase relationship between the recorded signals upon playback, as was present when the signals were originally recorded comprising generally, playback transducer means including a playback head, phase comparison to determine the phase relationship of the signal played back by the playback transducer means and to output a signal which is proportional to the magnitude and direction of any phase difference present, and electrically responsive driver means to adjust the playback transducer means to dynamically compensate for the phase error by rotating the playback head.
