The imaging unit thickness is less than about 4.0 .mu.m, using a total of no more than 2.0 parts by weight of silver per part of coupler. The imaging unit yields a density of at least 2.0 when exposed and processed.

Abstract: There are described a method for retouching photographic images, compositions adapted for such retouching, and photographic elements containing dye-forming couplers that yield dye images that particularly lend themselves to retouching by this method. The method comprises contacting a photographic element containing a dye image with a defined retouching composition to solubilize and remove selected areas or amounts of dye. The composition comprises an aqueous basic solution of a dinucleophile and a water-soluble organic co-solvent. The preferred photographic element for application of this retouching method comprises a dye image formed from a pyrazoloazole magenta dye forming coupler having a cleavable ballast group joined to the remainder of the molecule by one or two electrophilic cleavage groups. The retouching composition cleaves the ballast from the dye and solubilizes the dye, allowing it to be washed from the element.

Abstract: There are described color photographic elements containing novel release compounds which rapidly release a photographically useful group, such as a development inhibitor, from a timing group.

Abstract: The critical dimensions of product samples made during a standard certification procedure for an injection molding process are measured and a loss factor value is computed for each such dimension. Using statistical techniques, the largest loss factor value is partitioned into percentages of loss contributed by a predetermined set of loss elements. The loss element contributing the largest percentage is corrected so as to improve the quality of the process and the product. The method provides a way of determining what kinds of process corrections will most effectively improve product and process quality.

Abstract: Room light handleable direct reversal silver bromide emulsions, with up to 70 mole percent chloride, have a broad Dmin window when from 1.times.10.sup.-6 to 1.times.10.sup.-4 mole per silver mole of a polybromo coordination complex of iridium is incorporated in the silver halide grains. The emulsions are stabilized against deterioration on keeping with mercapto compounds.

Abstract: In a curtain coating apparatus for the coating of photographic film and paper webs and the like, the line of impingement of the curtain on the moving web is controlled by providing a pressure controlled zone on one side of the flowing curtain. Small changes in the static air pressure in the zone cause the position of the curtain to move without disturbing the quality of the curtain. Wetted side walls of the pressure controlled zone can serve as edge guides for the curtain.

Abstract: An apparatus for degassing a continuously flowing liquid stream comprising an air-tight housing, in which is mounted for rotation a centrifuge bowl of circular cross-section and having an inner surface for spreading centrifugally impelled liquid to be degassed and an annular peripheral trough for retaining centrifugally impelled degassed liquid. The liquid stream is fed into the bowl and the degassed liquid is withdrawn through a tube extending from an exit line outside the housing to an open end of elongate cross-section which is positioned within the trough of the bowl and is immersible in the degassed liquid. The apparatus further provides for measuring the pressure of the exiting degassed liquid, the pressure measurement being used to regulate the flow of liquid into the bowl so as to maintain a substantially constant level of liquid therein.

Abstract: There is described a system and method for reproducing an original record using a narrow band filter, such as a dichroic filter, to modify the contrast of the reproduction without modifying the color balance or the wavelength peak of sub-reocrds. The system is particularly useful in reproducing motion picture records where a multiplicity of additive lamp houses can be employed. The system reduces variations in contrast and color reproduction among different additive lamp houses.

Abstract: A new film cassette assembly comprises a thrust type cassette and a roll of a photographic film having particular properties. One such property is a low coefficient of friction between the emulsion side and back side of the film. In preferred embodiments the film has a stiffness sufficient to avoid buckling of the film when the film spool is rotated in the unwinding direction and is very thin. Most preferably, it is formed from a hydrophilic copolyester having the desired stiffness.
