  • Camera with viewing opening extended to hold label
    Patent number: 5842072
    Abstract: A camera comprising a door with an exterior viewing opening for viewing readable information appearing on a photographic article such as a film cartridge in the camera, and an interior light-trapping gasket that surrounds the viewing opening to confine ambient light entering the viewing opening when the door is closed, is characterized in that the viewing opening is extended along the door to hold a label at a particular portion of the viewing opening that does not interfere with ambient light entering the viewing opening to view the information.

  • Light reflector apparatus and method of making
    Patent number: 4570203
    Abstract: Improved light reflector apparatus for use in an electronic flash unit or the like is formed by an injection molding operation, which causes both precise shaping of a reflector and accurate mounting of the reflector securely within a housing. A light-reflecting flexible sheet is placed in a mold so that its light-reflecting front surface is centrally positioned adjacent a mold forming surface. The forming surface, which is larger than the sheet, has a contour adapted for shaping the sheet to reflect light into a beam of illumination. Liquid plastic is injected into the mold under pressure against the opposite surface of the sheet, thus pressing its light-reflecting surface into intimate contact against the forming surface. Because the sheet is smaller, the border of the forming surface is not covered by the sheet. Plastic flows beyond outer edges of the sheet against the uncovered border of the forming surface.
