Title: The Innovative Contributions of Richard F. Davis
Introduction
Richard F. Davis is a notable inventor based in Rochester, NY (US), recognized for his significant contributions to the field of radiography. With a total of 7 patents to his name, Davis has made remarkable advancements in imaging technology, particularly through his work on blue-sensitive films.
Latest Patents
Davis's latest patents include a blue-sensitive film for radiography with a desired image tone. This innovative film comprises a silver halide emulsion layer predominantly made of tabular silver halide grains. These grains have an aspect ratio of at least 15 and a grain thickness of at least 0.1 µm, containing at least 90 mol % bromide and from about 0.5 to about 2.75 mol % iodide. Notably, the iodide is localized within the grains, excluding the surface. The emulsion layer also includes a hydrophilic polymeric vehicle mixture with at least 0.5% oxidized gelatin. Additionally, the film incorporates a mercapto-substituted benzothiazole, benzoxazole, or benzimidazole to enhance image tone and processability.
Another significant patent by Davis is the blue spectrally sensitized film for radiography, imaging assembly, and method. This film also features predominantly tabular silver halide grains with similar specifications as his previous patent. The grains are spectrally sensitized using a combination of spectral sensitizing dyes, which provide increased speed and reduced dye stain. The dyes have maximum J-aggregate absorptions ranging from about 380 to about 500 nm, ensuring optimal performance in radiographic applications.
