  • X-Ray film marker
    Patent number: 4429412
    Abstract: A film support defines an x-ray permeable path and indicia such as the letters L and R are carried by an indicia support and the indicia support is movably mounted to the film support and overlies the x-ray path. The indicia are opaque to x-rays and the indicia support is arranged to alternately locate one indicia in the x-ray path and the other indicia out of the x-ray path so that when film is placed in the film support and is exposed to x-rays and later is developed, the film will have the image of one of the indicia imposed thereon.
