  • Patent number: 5873308
    Abstract: A black sheet is interposed between a manuscript and a porous resin and the manuscript face is irradiated by a linear light source moving along the manuscript face under a laminated state. By this process, the total face of the manuscript is irradiated, and a stamp face is formed by heat generation of the black sheet in accordance with a stamp pattern of the manuscript.

  • Patent number: 5812245
    Abstract: An asynchronous contact printer and a related method for printing motion picture film in different formats. The contact printer has a pair of film drives that move duplicate film and original film at different increments through the printer, and then intermittently stop the film to permit exposure of the original onto the duplicate. The printer can print duplicate film in an alternate format, such as the three-perforation or 2.5-perforation format, from original film in another format, such as the four-perforation format. This is accomplished by moving the film asynchronously through the printer and exposing frames of the original film onto the duplicate film on a frame-by-frame basis.

  • Patent number: 4208124
    Abstract: A platform-shaped device is designed to be placed over the illuminating aperture of a color-controllable light-box of known construction, and under a camera which is loaded with a roll of color film of slide-forming size and character, and which is focused on the central area of the platform. The device has at opposite sides a reel for holding, guidedly feeding and receiving a roll of developed black-and-white negatives previously made from the usually much larger black-and-white art work. The device also has means (e.g. a geneva-movement mechanism) for accurately sequentially positioning in the camera field, each one of a series of frames to be converted to color-slide frames in the camera. A pair of laterally movable thin blackened masking plates are manually movable in guides to expose different laterally constricted areas of the negative for each color to be projected therethrough from the light-box.

  • Patent number: 4157870
    Abstract: A microfiche duplicator exposure station where a copy sheet lies facewise over a master while an elongated lamp shines light through the master to expose the copy sheet. A shutter that controls exposure, includes two plates lying over the lamp and a solenoid that quickly pivots the plates to positions beside opposite ends of the lamp to allow light from the lamp to reach the microfiche. The plates have mirror surfaces extending at an incline of about 60.degree. from the vertical when the plates are at opposite ends of the lamp, to shine light onto opposite ends of the microfiche, to thereby compensate for low illumination thereat produced by an elongated lamp.

  • Patent number: 4043653
    Abstract: A holograph high resolution contact printer for use in transferring high resolution information, which is in the form of a pattern on a transparency, from the transparency to the light-sensitive photoresist material front surface of a light-recording medium having a light insensitive substrate rear surface, in which the light-sensitive photoresist surface previously has been exposed to a preselected diffraction grating, but the recording medium has not been developed.

  • Patent number: 4003652
    Abstract: Variation in the width of the shutter opening in a motion picture film copying machine is rapidly effected to control the amount of light passed through the shutter for transmission of the image from the master film onto the blank sensitized film running in registry therewith. Such rapid change in size of the opening in the shutter is effected by presetting the predetermined fixed extent of opening or closing of the opposed shutter halves in advance and shifting these halves to the scheduled predetermined position on signal from a sensor associated with the moving master film strip.

  • Patent number: 3953125
    Abstract: A contact copying device includes first and second plates which are spaced from and substantially parallel with each other, one of the plates having a slot therein. A pair of pickup rollers are provided for feeding superposed films, one of which is unexposed and sensitized, and the other of which includes information thereon which is to be exposed onto the unexposed film. The feed rate of the films past the slot is controlled and varied in accordance with the amount of light required to expose the sensitized film by a source of electromagnetic energy spaced from the slot.
