    Abstract: The values of a plurality of data signals to be plotted against time as curves on a moving photosensitive record sheet are sampled by being simultaneously compared continuously with a single cyclically repeated ramp voltage by a plurality of comparators. Each of the latter produces an output each time that the ramp voltage just exceeds the value of the corresponding signal. The ramp voltage is synchronized with the horizontal sweep for a fiber optics cathode-ray tube, across the optics strip of which the record sheet is advanced at right angles. An EXCLUSIVE OR gate for each signal unblanks the normally blanked beam of the tube for a period in each sweep to mark a line on the sheet. Each period is that in which the ramp voltage lies between the two values of the corresponding signal at which the corresponding comparator output is produced for the present and the immediately previous sweeps. The lines produced for each signal combine to form a recorded curve for that signal. In one form, each gate is controlled by the corresponding comparator output applied both directly and through a device providing a delay of one sweep period. In another form, each gate is controlled by two comparator outputs, one based on the present value of the corresponding signal, and the other based on a stored value of that signal from the previous sweep.

    Abstract: An adapter for recording a video picture upon a light-sensitive recording medium is connected between a video camera and a fiber optics cathode ray tube recording apparatus. The adapter modifies the input signal received from the camera to generate synchronized horizontal and vertical sweep signals and to modulate the intensity of the electron beam, formed by the cathode ray tube, in response to the video signal. The adapter also blanks alternate fields for allowing a continuous series of picture frames to be recorded upon the recording medium passing over the face plate of the fiber optics cathode ray tube.

    Abstract: A printing device is shown that uses a specially adapted paper upon which alphanumeric characters may be printed without impact and from which erroneously printed characters may be removed. The alphanumeric character to be printed is selected by a keyboard which electrically energizes core elements within a recording head. The core elements generate a force field that reorients preoriented highly reflective flakelike particles within the specially adopted paper. The reorientation causes the reflective flakelike particles to become absorbtive for forming a dark contrasting trace upon the paper which represents the selected alphanumeric character. If an error is made, the recording head may be utilized to remove the erroneously selected alphanumeric character by again reorienting the reflective flakes into their previous light-reflective orientation.

    Abstract translation: 显示了一种打印设备，其使用特别适合的纸张，可以在其上打印字母数字字符而没有冲击，并且可以从中删除错误打印的字符。 要打印的字母数字字符由对记录头内的核心元件进行电激励的键盘选择。 核心元素产生一个力场，在特别采用的纸张中重新定向预取向的高反射片状颗粒。 重新定向导致反射片状颗粒变得吸收，以在表示所选择的字母数字字符的纸上形成暗对比度迹线。 如果发生错误，则记录头可以用于通过再次将反射片重新定向成其先前的光反射取向来去除错误选择的字母数字字符。
