  • Patent number: 5812895
    Abstract: An automated film encoding and decoding system for bringing photographic film from the state of exposure to subject matter through all of the processes required to produce finished photos and package the same. The system includes an encoder coordinately operative with a camera for the placement of a human and machine readable code on the film the decoder capable of reading the code for the control of production-processing equipment in laboratories provided with such equipment. The human readability of the code accommodates production-processing of the film by attendant personnel and also allows for quality control check of automated production-processisng equipment. The encoding includes film frame identification information, subject matter information and registration mark information all of which may be utilized on a single exposure situation.
    Type: Grant

  • Patent number: 4338762
    Abstract: A photographic film insertion apparatus inserts photographic film segments into an insertion opening of a multi-layer package strip. A film conveyor conveys cut photographic film segments along a path and discharges the photographic film segments from a discharge end of the conveyor to the film insertion opening. After the film segments have been conveyed into the insertion opening, a film pushing element drives the film segments a further distance into the insertion opening. This ensures that all film segments are securely within the insertion opening and will not hang up or tip as the multi-layer package strip is advanced away from the film insertion station.

  • Patent number: 4099864
    Abstract: An improved light source for a photographic printer uses a plurality of print lamps. A heatsink and blower dissipate heat generated by the print lamps. The light diffuser which diffuses light from the lamp includes a white porcelain diffuse reflector.

  • Patent number: 4017179
    Abstract: An automatic density control device for photographic printers for sensing and correcting for a "subject failure" in a photographic negative, where the subject area of the negative is out of the optimum density ratio to the background area, which device includes a frusto-pyramidal radiation directing member having its enlarged end proximate to the negative and its small end remote therefrom and being positioned to receive the radiation from a source through the negative and having subject sensing means mounted at the central portion of the enlarged proximate end of said member to sense the radiation passing through the central subject area of the negative and also having background sensing means mounted at the diminished remote end to sense the radiation passing through the marginal portions of the negative and the marginal portions of the enlarged end of said member and including circuitry for comparing the signals produced by said subject sensing means and background sensing means and thus deriving a density
