  • Patent number: 4331275
    Abstract: A high precision strip film drive, typically for microfiche film, that includes two spaced-apart drive rollers, separately driven by two servo electric motors. The motors are biased against each other and so maintain a constant tension on the film, while it is stationary or moving.The motors are logic controlled through a pair of rotary encoders. Each encoder is driven by one roller. The outputs of the encoders are combined to give a single servo control signal, devoid of film squew, for accurately spacing the frames upon the microfiche.The encoder electrical outputs are differently handled to provide film velocity information, and still further differently handled to provide direction of motion of the film information.Transverse orthogonal motion of the film is provided by a carriage that supports the rollers, a linear encoder, and a cable system actuated by a third servo motor.The encoder electrical outputs are even further differently handled to accurately finally position the film, as preselected.

  • Patent number: 4325632
    Abstract: By providing a photographic original plate on which an original picture image and a light-shielding mask are formed, two identical pictures can be formed by exposing a sheet of photosensitive material with the original plate placed thereon and repeating the procedure after rotating the original plate 180 degrees about a point which is located outside of the picture image and the light-shielding mask. Though the two printed images are inverted relative to each other, the final prints are eventually cut apart along a central line and no problem arises. Through adoption of the method and the use of the novel photographic original plate, not only the printing process becomes simpler than conventional method but a better result in the final prints can be obtained.

  • Patent number: 4287564
    Abstract: A method of reading selected ones of an array of data frames from a microfiche medium substantially without errors attributable to misalignment of the frames. The method, which utilizes a microfiche reader-printer in adjusting for misalignment of the frames, includes the steps of determining the average distance between the frames along a first selected axis (e.g., the X-axis) of the array, and using said average distance in positioning the frames along the axis for reading. The frames are separated from each other by a predetermined nominal distance along the axis. The average distance is determined by dividing the distance between the outermost frames along the axis (the distance between the outermost frames being expressed in terms of the number of stepper motor steps needed to traverse said distance) by one less than the number of frames along said axis to produce a quotient, and adding the quotient to the predetermined nominal distance.

  • Patent number: 4142794
    Abstract: A step-and-repeat registration system is disclosed for making multiple-image plates for use in flexographic printers or the like. The negative which carries the image to be transferred to a light-sensitive film, is referenced with respect to a fixed frame. An incremental step registration system accurately positions the film at a succession of predetermined stations to bring different portions of the film opposite the negative. At each station the film is brought into contact with the negative and an exposure is made on the pertinent film portion, using a light source to project the image onto the film. The registration system provides high accuracy and lends itself to partial or complete automation.

  • Patent number: 4120583
    Abstract: A machine and a control system are provided for generating high registration photomasks with a contact printing arrangement. Further, a unique control arrangement is provided for controlling a machine such as a high registration contact print machine or other type of machine. In a preferred embodiment, a control system generates signals to a step and repeat contact printing machine that exposes many prints of master die images on a photographic film, where these prints have a high registration characteristic. In a further embodiment a unique control arrangement is provided for machine control operations.

  • Patent number: 4094605
    Abstract: An apparatus for producing identical flat carriers each having an identical representation thereon, by the steps of providing a plurality of individual representations on a flat material in a predetermined mutual relationship, providing at least two reference marks on the flat material in predetermined relationship with respect to the representations, mounting the flat material carrying the representations in a preset position relative to a punch device by means of the reference marks and successively punching out the individual carriers from the flat material by the punch device.

  • Patent number: 4058359
    Abstract: Copying apparatus of the type in which an original after being passed through a copying path with a copy sheet can be either delivered away or passed back through a return path into the copying path for making another copy is provided with a simple and reliable system for adjustably positioning a side edge of the original, even if it is fragile, relative to a side edge of the copy sheet so that the position of the images on multiple copies will not vary from copy to copy.

  • Patent number: 4047813
    Abstract: A microfiche or microfilm editing device in which a microfilm or microfiche to be edited is supported on a frame arranged to be driven in an x and y axis directions according to a program, the movements being relative to a copy axis. Also movable in relation to the copy axis is a microfiche holding means arranged to be driven by actuators in a similar fashion to the first microfiche or microfilm and according to a further program. In order to illuminate the image to be transferred to the first film to the second film a light source condenser and at least one light transfer block is arranged to project light along the copy axis. Several light transfer blocks may be mounted on a rotatable turret so that different blocks may be provided for different microfiche or microfilm standards.The editing device is arranged so that microfiches can be updated according to a set program or alternatively microfilm can be changed to microfiche or microfiches and one standard can be changed to microfiches of another standard.

  • Patent number: 3972610
    Abstract: Apparatus for electrophotographically imaging a photosensitive film in which a fractional area of the film, selected by automatic or preprogrammed access, is electrostatically charged and thereafter exposed to a pattern of radiation, is moved along a path of travel to a second location at which the latent image is developed by the application of toning fluid, and is preferably returned along the path of travel to fix or fuse the developed image as a next adjacent area is indexed for exposure. Additional areas of the film may be sequentially imaged by repeating the above sequence or by reinserting the partially completed film at a later time and addressing any desired used or unused area.
