Title: Gino L De Rycke: Innovator in Photographic Materials
Introduction
Gino L De Rycke is a notable inventor based in Mortsel, Belgium. He has made significant contributions to the field of photographic materials, holding a total of 9 patents. His work primarily focuses on the development of X-ray materials and photographic developing solutions.
Latest Patents
One of his latest patents involves an X-ray silver halide photographic material suitable for rapid processing. This invention describes the preparation of X-ray materials that are particularly effective for non-destructive testing applications. The emulsion layers of this material consist of silver halide emulsion grains containing at least 75 mole % of silver chloride and less than 25 mole % of silver bromide. The material is characterized by a specific ratio between the amount of gelatin and the amount of silver halide, expressed as the equivalent amount of silver nitrate, being less than 0.6. The hardening process ensures that the amount of demineralized water absorbed in 3 minutes is less than 2.5 g per gram of gelatin present. Additionally, a rapid processing system is available with a total processing time of less than 3 minutes, utilizing a developer and fixer that are substantially free from hardening agents and ammonium ions.
Another significant patent involves a photographic developing solution for immersion development. This solution has a pH of at least 12.0 and contains more than 0.4 moles/liter of a sugar derivative, or an alkali metal salt thereof. The preferred sugar derivatives include l-ascorbic acid and iso-ascorbic acid. This invention allows for the development of graphic arts photographic material with lith quality while ensuring that the disposal of depleted solutions is ecologically safe.
