Abstract: A method and apparatus (10) referred to as a step and repeat sensitometer directs radiant energy (18) from a radiant energy source (16) into a diffuse integrating chamber (2) which uniformly mixes and directs the radiant energy (18) onto an exposure plane (14) where a radiation sensitive sample (1) is positioned so that individual areas of the sample (1) are exposed to readily adjustable levels of illuminance producing gradated exposures.

Abstract: An apparatus for enlarging and printing panoramic photographs includes a light source and a negative shuttle having upper and lower parallel plates for securing and enclosing entirely a negative placed therebetween. Interposed between the light source and the negative shuttle is a focusing device for concentrating light emanating from the light source. The three above-described elements are operative to project an image from a negative secured in the negative shuttle in a direction opposite the light source. A lens is supported in an adjustable lens support for magnifying and focusing the image projected from the negative shuttle. Photosensitive material is supported on a supply spool, the photosensitive material being passed to a take-up spool adapted to receive the photosensitive material. A photosensitive material is supported in substantially parallel relation to the negative shuttle and is exposed to the image projected through the lens.

Abstract: A film code reader assembly for a film scanner provides film path for accurately guiding the scanning film past a film code reading location where optically readable film codes are extracted by a code reader. The assembly self-aligns the film code reader in a direction perpendicular to the scanning direction of the film, and orients film film code reader with respect to the film code-bearing edge of the scanning film.
