Title: Harold G Judd: Innovator in Photographic Technology
Introduction
Harold G Judd is a notable inventor based in Bolingbrook, IL (US), recognized for his contributions to photographic technology. He holds 2 patents that showcase his innovative approach to enhancing photographic processes.
Latest Patents
One of his latest patents is the "Scalable impeller apparatus for preparing silver halide grains." This invention features a mixer designed for preparing silver halide grains used in photography. It includes upper and lower impellers housed in a draft tube, with the bottom impeller equipped with flat blades for micromixing silver and halide reactants. The upper impeller has pitched blades for macromixing the bulk fluid. The design allows for independent operation of the impellers, ensuring effective mixing without vortexing, aided by a flow disrupter and optional baffles.
Another significant patent is the "Process for the preparation of silver halide emulsions having iodide." This process involves creating a photographic emulsion with radiation-sensitive silver iodohalide grains. Iodide is introduced into the grains by releasing iodide ions from iodate, enhancing the uniformity of iodide availability during emulsion preparation. This method demonstrates a speed-granularity advantage, particularly in the partial halide conversion of tabular grains.
