1	Photocomposing device and method	US24731	1979-03-28	US4248509A	1981-02-03	Louis M. Moyroud
Lens alignment means is provided whereby mis-alignment is amplified by a lens system, is detected by a photocell array, is electrically encoded, and the coded information is stored and used to correct electronically the character placement so as to properly position characters on the film. A detailed description of this feature appears herein under the heading "CHARACTER ALIGNMENT", and in FIGS. 18 through 20 of the drawings. Master characters are packed more densely on the matrix by allocating each an area comprising one-third to two-thirds of the usual character area, and using a separate illumination device to illuminate each such separate area. The illumination devices can be energized in different combinations to illuminate characters of various sizes. A detailed description of this feature appears herein under the heading "CONCENTRATION OF MASTER CHARACTERS", and in FIGS. 34 through 40 of the drawings.
2	Self testing phototypesetter flash intensity control system	US644387	1975-12-29	US4020495A	1977-04-26	Peter R. Ebner; Louis E. Griffith
An optical sensor is positioned at the output of a variable magnification optical system which focuses differing character size images upon a photosensitive medium. A reference voltage, which is a function of the proper exposure for a particular photosensitive medium, is compared with the photosensor voltage. The system automatically tests for the correct light flux before each size change by projecting a reference image through the optical system at the photosensor, such image having a relatively low intensity level, so that no output signal is produced by the above-mentioned comparator. The intensity of the reference image is iteratively increased until such output signal is produced by the comparator, thereby to maintain the light intensity at the last level attained, until a character size change is effected, wherein the comparison process is repeated. Upon the substitution of another photosensitive medium having a different sensitivity, the comparator threshold voltage is altered accordingly to produce the proper illumination intensities for various character sizes tailored to the sensitivity of the second photosensitive medium.

6	Laser photocomposition system and method	US549844	1975-02-13	US4044363A	1977-08-23	Grant T. Morgan
Type characters are formed on a photo-sensitive surface by projecting a laser beam directly onto the photo-sensitive surface while moving the beam rapidly upwardly and downwardly, moving the beam steadily in a horizontal direction, and blanking the beam at selected times during the vertical movements. The horizontal movement gives horizontal dimensions to the characters and proportionally spaces them from one another to form composed lines of characters. The blanking of the beam is accomplished by providing a barrier near the optical path of the beam, and using an acousto-optic modulator to rapidly deflect the beam out of its path and against the barrier. A programmed computer is used to store information regarding the start and the stop of each blanking interval for each vertical stroke forming each of the characters of a substantial number of fonts of characters. An optical-electric feedback system is used to indicate the precise position of the laser beam relative to the photo-sensitive surface. This feedback arrangement includes a beam splitter for capturing a portion of the laser beam and projecting it onto an optical grating which is located in a fixed spatial relationship to the photo-sensitive surface. A photo-electric detector is used to detect the position of the laser beam and provide an electrical signal to time the operation of the vertical scanning and blanking devices. The speed of the machine preferably is increased by detecting the height of the characters in a line to be composed and, if the maximum height of any character is below a pre-determined level, then reducing the vertical scan distance traveled by the laser beam while increasing the horizontal and vertical scan rates.

A system for directing light in a photocomposer to a selected character to participate in the formation of an image thereof. The photocomposer has a maxtrix provided with characters uniformly arranged in rows which are adapted selectively to be positioned at a projecting position where a selected character in the row at the latter position can have its image projected onto a light-sensitive member. A plurality of elongated light-guide members are respectively provided with light-discharge ends respectively aligned with the characters in a row at the projecting location, and these light-guide members have lightreceiving ends distant from their light-discharge ends. A single light source is provided for illuminating a selected character, and a light-directing structure coacts with this single light source to direct light therefrom to the receiving end of a selected light-guide member, so that light will travel therethrough to the discharge end thereof for illuminating a selected character in a row which is at the projecting location.

11	Photohead with flashing beam	US284780	1981-07-20	US4363539A	1982-12-14	Heinz J. Gerber
A photoplotter for use in exposing graphics or artworks on a photosensitive surface by directing a small beam of light onto the surface and moving it relative thereto has an output beam which is repetitively flashed as it is moved over the surface to expose a line. The flashing light beam is produced by intercepting a stationary beam with a cyclically moving mirror to periodically sweep it across a light accepting window, the light energy received by which is directed to the photosensitive surface. The cross-sectional size of the output light beam may be varied to vary the size of the light spot which it creates on the photosensitive surface and to therefore vary the width of the exposed line, and changes in the character of the output beam may be made in accordance with changes in the size of the spot and with changes in its speed relative to the photosensitive surface in order to obtain a desired exposure of all portions of the exposed lines. The photohead may also be designed to deliver a beam of selectively variable color to the photosensitive surface for exposing colored graphics on a color sensitive surface, and two or more beams may be combined into the single delivered output beam to produce a beam of desired color or intensity.
12	Photocomposing machine	US792104	1977-04-29	US4141632A	1979-02-27	Roger E. Mitchell
A photocomposing machine includes a fiche-like type font having positive and negative character fields, an optical system having a variable magnification and automatic focus compensation for imaging characters on a film strip, and means for conveniently and rapidly selecting individual characters of the positive field of the type font and moving them into alignment with an index light, which simultaneously positions the corresponding negative character in the optical path. A font carrying frame is mounted for simultaneous and direct X and Y movement with respect to the optical path for rapid selection of characters. The object portion of the optical components including the font, and the lens assembly are movable with respect to each other and with respect to the image plane to vary magnification. An automatic focusing cam maintains the focus of the image for all magnifications. The exposure lamp is used in a full power mode for exposure, and in a reduced power mode as the safe light, and means are provided for automatically adjusting the exposure time and the safe light intensity in accordance with different magnifications.
13	Automatic base line correction for p/t (photocomposing machine)	US598786	1975-07-24	US4040066A	1977-08-02	Henry L. Brill; Jacob H. Moody
A method of using photocomposition technology to insure all characters falling on a common text base line when multiple lenses are used to change point size in a line of text. Each lens is tested by deliberately setting the flash circuit to be armed by its dedicated timing mark to flash before the character is properly aligned with the optical system. Then from a memory record produced by a previous test program, the flash is delayed by the count in memory. Therefore, the mechanical positioning of a plurality of lenses in a turret may be only reasonably accurate, and not be responsible for misplacing characters off of the text base line when lenses are intermixed during composition of that base line of text.
