    Abstract: Apparatus is provided for displaying configurations on a surface, such as the face of a cathode-ray tube, with a energy beam, such as a cathode-ray tube electron beam. The beam is deflected with reference to first and second perpendicularly related axes in response to positioning signals for positioning the beam on the surface at selected positions in accordance with position command signals. A control circuit provides configuration signals for sequentially positioning the beam relative to the two axes to provide a plurality of incrementally spaced images which, in turn, define a configuration. The magnitude of the configuration signals is dependent on the selected position, and a configuration size control circuit serves, in response to size command signals, to change the magnitude of the configuration signals and thereby change the size of the configuration.

    Abstract: A PHOTOTYPESETTING METHOD AND APPARATUS UTILIZING A CATHODE-RAY TUBE TO DISPLAY CHARACTERS ONE AT A TIME ON THE FACE THEREOF FOR PHOTOGRAPHIC RECORDATION EMPLOYS AN OPTICAL CHARACTER DISC HAVING FORMED THEREON A FONT OF CHARACTERS IN THE FORM OF A PLURALITY OF BINARY BITS REPRESENTED BY OPTICAL MARKS. THE CHARACTER DISC IS USED IN CONJUNCTION WITH CONTROL SIGNALS FROM A CONTROL RECORD TO FORM CHARACTERS OF VARIOUS SIZES ON THE CATHODE-RAY TUBE. A BUFFER MEMORY CIRCUIT ACCEPTS INFORMATION IN PARALLEL FORM FROM THE CONTROL RECORD, CONVERTS THIS INFORMATION INTO SERIAL FORM, STORES THIS INFORMATION UNTIL IT CAN BE USED BY THE TYPSETTING SYSTEM, AND THEN RECONVERTS IT TO PARALLEL FORM FOR UTILIZATION BY A DECODER CIR-

    CUIT WHICH PROVIDES THE SIGNALS NECESSARY FOR THE CONTROL FOR VARIOUS TYPESETTING OPERATIONS AND FOR THE SELECTION OF THE CHARACTERS TO BE DISPLAYED. ELECTRONIC CIRCUITS COMPENSATE FOR THE NONLINEARITIES IN THE CATHODE-RAY TUBE TO PERMIT CHARACTERS TO BE FORMED ON THE FACE THEREOF IN PROPERLY SPACED RELATION AND WITHOUT DISTORTION REGARDLESS OF THEIR POSITION ON THE TUBE. OTHER ELECTRONIC CIRCUITS ARE EMPLOYED FOR THE GENERATION OF THE CHARACTERS AS CONTROLLED BY THE BINARY BITS ON THE CHARACTER DISC, FOR CONTROL OVER THE CATHODERAY TUBE INTENSITY, AND FOR LEADING OF THE PHOTOGRAPHIC RECORDING MEDIUM.
