Abstract: A stencil apparatus which can be releasably secured to an upper surface of a substrate. The stencil apparatus comprises a stencil material which is deformable to accept impression of indicia and also enables the reproduction of the impressed indicia on another surface. The stencil apparatus further can include a substantially continuous frame which defines an opening and is attached to a marginal portion of the stencil material. The opening is large enough to permit the stencil material to contact the substrate in an unobstructed manner for transfer of the impressed indicia onto the substrate. The present invention is cleanly and releasably secured to the substrate. The apparatus attaches such that objectionable residues do not remain on the substrate and the stencil apparatus after the stencil apparatus is released therefrom. The apparatus is designed to be producible in a roll which is suitable for use on label affixing equipment.

Abstract: A sheet suitable for making typewriter producible negatives to impart an identifying title to light-sensitive material which comprises an opaque sheet formed with a narrow rectangular area defined by spaced parallel perforations in the sheet affording removal of the sheet material from the rectangular area and a carbon ribbon secured to the sheet such that typing on the ribbon transfers the carbon to the removable sheet material in the rectangular area affording transparent areas in the ribbon defining the indicia desired for the title.
