Title: The Innovative Contributions of Mary H. Delton

Introduction

Mary H. Delton is a notable inventor based in Honeoye Falls, NY (US). She has made significant contributions to the field of emulsions, particularly in the development of tabular grain emulsions. With a total of 7 patents to her name, her work has had a profound impact on photographic technology.

Latest Patents

Among her latest patents is the invention titled "Chloride containing high bromide ultrathin tabular grain emulsions." This patent describes tabular grain emulsions where the grains have average thicknesses of less than 0.07 µm and average equivalent circular diameters of at least 0.7 µm. The incorporation of at least 0.4 mole percent chloride, along with over 50 mole percent bromide and optionally iodide, enhances these emulsions. The resulting emulsions exhibit reduced pressure sensitivity, increased developability, and reduced native sensitivity to the blue region of the spectrum. Another significant patent is the "Process for the low pAg preparation of high aspect ratio tabular grain." This process involves preparing a high bromide high aspect ratio tabular grain emulsion, where grain growth occurs in a temperature range of 30°C to 90°C within a low pAg window.
