Patent number: 6482579Abstract: Color negative photographic elements can be effectively processed to provide negative color images using bleaching or bleach-fixing compositions in which the primary bleaching agent is a ferric complex of 1,3-propylenediaminetetraacetic acid or a salt thereof. Any potential precipitation of the bleaching agent is inhibited by the presence of at least 0.005 mol/l of an organic polyphosphonic acid, an aminopolysuccinic acid, or a polycarboxylic acid containing at least one hydroxy group as a compound. This compound can be added directly to the bleaching or bleach-fixing composition or introduced from carryover from a previous photoprocessing step.Type: GrantFiled: February 5, 2001Date of Patent: November 19, 2002Assignee: Eastman Kodak CompanyInventors: Jon A.

Patent number: 5376523Abstract: A process for controlling the silver halide grain-to-grain distribution of a variable contrast dye in a light sensitive silver halide emulsion layer of a variable contrast photographic element, and thereby adjusting the low contrast characteristic curve of the element, is disclosed comprising the process steps of adding a green variable contrast sensitizing dye of the following formula (I) to a silver halide emulsion for a variable contrast photographic element, adding a blue sensitizing dye of the following formula (II) to the same silver halide emulsion, and coating the emulsion on a support. In the process, the green and blue sensitizing dyes are added to the emulsion at substantially the same time, and the green dye is added in an amount less than that required to impart maximum sensitivity to all of the silver halide in the emulsion. ##STR1## In formula (I), R.sup.1, R.sup.2, R.sup.6 and R.sup.Type: GrantFiled: October 4, 1993Date of Patent: December 27, 1994Assignee: Eastman Kodak CompanyInventors: Marian S.

Patent number: 4769918Abstract: The invention relates to a level indicating device including a container or reservoir and a length of tubing extending from the container near the bottom thereof. Narrow, inverted cups are adhered to the sides of the container so that they may be slipped over the top of a stake driven into the ground to provide a firm, stable support for the container while the tubing is moved to different locations to establish a reference horizontal plane.Type: GrantFiled: April 13, 1987Date of Patent: September 13, 1988Inventors: Harry J. Price, Paul B. Price

Patent number: 3964912Abstract: A composition is disclosed useful in developing silver halide photographic elements containing specifically selected developing agents for silver halide and a ruthenium(II) or ruthenium(III) cationic complex as a development accelerator. The ruthenium complex includes a predominance of amine or ammine ligands. Each of the developing agents exhibits an induction period in the absence of the ruthenium complex in excess of about 5 seconds. Polyhydroxybenzene, ascorbic acid, hydroxylamine, hydroxyurea and pyrimidine developing agents are representaive of those which are useful in the practice of my invention. A method of accelerating photographic development using the above composition is also disclosed.Type: GrantFiled: December 29, 1975Date of Patent: June 22, 1976Assignee: Eastman Kodak CompanyInventor: Harry J.
