Abstract: An alphanumeric recording system wherein a character disc having transparent character images thereon is rotated through an exposure zone so that selected characters may be projected by the energization of a flash lamp. The projected image is collimated and directed to a recording zone through which move lens-mirror units at a constant speed intercept the projected image and focus it onto a photoreceptive recording medium. The character disc rotates at a rate such that with the slits therein associated with respective characters inter-character spacing is assured. Dead time in the recording process is eliminated by the use of the collimated projected character image and plural interception of that image.

Abstract translation: 一种字母数字记录系统，其中在其上具有透明字符图像的字符盘旋转通过曝光区域，使得可以通过闪光灯的通电投影所选择的字符。 投影图像被准直并被引导到记录区域，通过该记录区域以恒定速度移动透镜镜单元拦截投影图像并将其聚焦到感光记录介质上。 字符盘以这样的速率旋转，使得通过其中与各个字符相关联的狭缝确保字符间距。 通过使用准直投影的字符图像和多次截取该图像来消除记录过程中的死时间。

Abstract: A recording system wherein a character disc or the like having transparent light modulating patterns thereon is rotated through an exposure zone so that selected patterns may be projected by the energization of a flash lamp. The projected pattern is collimated and directed to a recording zone through which move lens-mirror units at a constant speed that intercept the projected pattern and focus it onto a photoreceptive recording medium. The patterns are arranged on the character disc in spiralled configurations such that as the disc is rotated the first and last patterns of a spiral move through a fixed exposure zone at different positions relative thereto.

Abstract: A circuit is provided for regulating the application of power to a load which is relatively insensitive to rapid power fluctuation of the type exemplified by typical AC line sources. In one embodiment, an AC line source is applied, via a full wave rectifier, at a controlled rate to a tungsten lamp whose operation is controlled by a transistor switching network. The transistor operation, in turn, is controlled by comparing a portion of the rectified signal with a signal proportional to the light output of the lamp.
