Abstract

9005. Gaisman, H. J. April 14, 1913, [Convention date]. Drawings to Specification. Identification marks and the like, producing on negatives by exposure.-A sensitive film or plate is provided with an opaque covering-layer (carbon transfer paper, for example) consisting of or carrying displaceable or removable opaque material, so that, when written upon or scratched or cut into, it is rendered translucent at the parts touched by the writing - instrument, thus enabling the written identification mark to be produced by the action of light on the film or plate, for example before the film &c. is exposed in the camera.
