摘要： An apparatus and method for mixing at least two reactants is taught wherein a first reactant is delivered to a reaction zone through a first annular flow path and a second reactant is delivered to the reaction zone through a second annular flow path. The first and second annular flow paths are concentric with one another and the two reactants intermix with one another in the reaction zone. There is a rotating disc having a surface, defining one boundary of the reaction zone. The flow of the first and second reactants across the rotating disc and through the reaction zone is generally radial and has a residence time in the reaction zone of not more than about 100 msec, and preferably not more than about 50 msec. The reaction zone resides in a main reactor vessel and there is a driven agitator residing in the main reactor vessel to stir the contents thereof.

摘要： A process for the preparation of a radiation-sensitive silver halide emulsion comprised of high bromide cubical silver halide grains is described, the process comprising: (a) providing in a stirred reaction vessel a dispersing medium and high bromide silver halide seed grains, the seed grains comprising at least 5 mole % of the final emulsion silver, and (b) precipitating a silver halide shell which comprises at least 5 mole % of the final emulsion silver onto the seed grains by introducing at least a silver salt solution into the dispersing medium at a rate such that the normalized shell molar addition rate, Rs, is above 1.0×10−3 min−2, Rs satisfying the formula: R s = M s M t ⁢ t s 2 where Ms is the number of moles of silver halides added to the reaction vessel during the formation of the shell, ts is the run time, in minutes, of the silver salt solution for the formation of the shell, and Mt is total moles of silver halide in the reaction vessel at the end of the precipitation of the shell; wherein the concentration of silver halide grains in the reaction vessel at the end of the precipitation of the shell is at least 0.5 mole/L. The invention provides an improved manufacturing process for the preparation of high bromide silver halide cubical grain emulsion enabling concentrated emulsion batches to be prepared with desired photographic properties. In certain embodiments of the invention, further advantages are enabled in accordance with the discovery that when the exterior portion of high bromide silver halide cubic grains are grown under specific conditions of high molar addition rates, emulsions of enhanced sensitivity, improved contrast and radiographic curve shape may be produced while controlling the minimum fog level.

摘要： A radiation-sensitive emulsion is disclosed comprised of cubical silver halide grains containing from 0.05 to 3 mole percent iodide, based on total silver, and an iridium coordination complex dopant, wherein (i) the iodide is incorporated in the grains in a controlled, non-uniform distribution forming a core containing at least 50 percent of total silver, an iodide free surface shell having a thickness of greater than 50 Å, and a sub-surface shell that contains a maximum iodide concentration, and (ii) the iridium coordination complex dopant is incorporated into the sub-surface shell or into a region of the core extending up to 60% of the total silver into the grain from the sub-surface shell. Speed and reciprocity of iodochloride emulsions can be improved by localized addition of known in the art reciprocity-controlling iridium dopants in relation to high iodide region of the grain. By carefully incorporating reciprocity-controlling dopant within a well defined band within a grain the difficulties of the prior art can be overcome.
