Abstract: A method is disclosed of extracting two or more spectral image records from an imagewise exposed multicolor photographic element containing a plurality of tabular grain emulsions for individually recording imagewise exposure in at least two different regions of the visible spectrum. In each of the tabular grain emulsions tabular grains exhibiting a mean equivalent circular diameter of greater than 0.4 micrometer and a mean thickness of less than 0.2 micrometer account for greater than 90 percent of total grain projected area. No more than one of the tabular grain emulsions exhibits a mean tabular grain thickness of less than 0.07 micrometers, and each of tile remaining tabular grain emulsions exhibit a coefficient of variation of tabular grain thickness of less than 15 percent. The mean tabular grain thickness of emulsions for recording imagewise exposure to different regions of the visible spectrum differs by at least 0.02 micrometer.

Abstract: A radiation image storage panel includes a layer of transparent stimulable phosphor, a filter layer for strongly absorbing stimulating radiation and transmitting emitted radiation, and a radiation diffusing layer. The filter layer absorbs the beam of stimulating radiation so that an image recorded in the storage panel is not blurred by scattered stimulating radiation during readout, and the diffusing layer increases the escape efficiency of the emitted light from the storage panel.

Abstract: A linear light source for a film scanner includes means for generating an intense beam of light and an elongated cylindrical integrating cavity having diffusely reflective walls, and defining an input port through which the intense beam is introduced into the cavity and an output slit parallel to the long axis of the cylindrical integrating cavity to emit a uniform line of light.

Abstract: In apparatus for scanning a transparent original with a scanning beam relative an optical axis, a tapered optical bar is positioned adjacent the transparent original to collect a diverging beam emerging from the original and, by means of internal reflection, reduce the divergence of the beam relative the optical axis. The emerging beam is especially diverged when the scanning beam sweeps away from the optical axis or is scattered by an artifact, such as a scratch, on the original. Particularly in the case of a polychromatic beam emerging from a color transparency, the tapered bar is interposed between the transparency and color dichroic beam separating mirrors to reduce angle shift and polarization color shading due to light rays diverging from the optical axis upon the dichroic interference layers.

Abstract: An illumination system for a photographic printer having a printer lens and a film gate, includes a light source for producing a beam of light directed toward the film gate, reflecting means disposed between the light source and film gate for intercepting peripheral portions of the beam and redirecting the peripheral portions toward the film gate, so that the light emerging from the reflecting means has a characteristic angular spread of between about .+-.35.degree. and .+-.65.degree., and means for conditioning the light emerging from the reflecting means such that the image produced by the printing lens is substantially uniformly illuminated, and such that the angular spread of the light is not substantially increased, thereby providing a relatively highly efficient scratch suppressing illumination system.

Abstract: A shelf bracket adapted to be secured to an upright by means of a bracket clip. The shelf bracket comprises attachment means for attaching the bracket to the upright. The attachment means comprises a slot adapted to receive the bracket clip thus removably securing the bracket to the upright.A shelf bracket-stud combination is disclosed which comprises a stud, a bracket clip, and a shelf bracket. The shelf bracket comprises attachment means for attaching the bracket to the stud. The attachment means comprises a slot adapted to receive the bracket clip such that the location of the bracket on the stud may be varied by varying the position of the bracket clip within the slot.Also disclosed is a shelf bracket-clip combination which comprises a bracket clip and a shelf bracket. The shelf bracket comprises attachment means for attaching the bracket to a stud.

Abstract: The invention relates to a corner key reinforcement brace for strengthening the joint between the beveled ends of abutting tubular metal members such as found in the frame of metallic storm or screen doors. The corner key is internally slip-fitted within each of the adjacent, abutting frame members in a manner so that a relatively close tolerance is maintained between the inner walls of both tubular members and the corner key. The corner key is formed of two substantially identical half sections having first and second leg portions disposed at substantially right angles to one another. All of the leg portions are substantially U-shaped in transverse cross section with one pair of corresponding legs having the top edges of the sidewalls thereof bent inwardly.
