Latest Patents

English’s listed patents address ways to supply and replenish processing solutions in photographic equipment.

“Photographic Processing Arrangement and a Processing Solution Supply Cartridge for the Processing Arrangement” describes a single-container cartridge for a single-part developer concentrate. The container has at least two valves or necks, allowing developer to flow into an existing processing machine through multiple openings at once. The design aims to empty the container more completely, reduce leftover solution, and avoid metering separate developers from separate containers.

“Direct Photographic Bleach-Fixing Replenishment Using Ferrous Bleach-Fixing Precursor Composition” concerns replenishing photographic bleach-fixing solutions directly in a processing chamber. Its single-part precursor composition includes iron-ligand complexes and thiosulfates as the sole fixing agents, with an optional sulfite preservative. The patent describes converting enough ferrous ions to ferric ions immediately before or during delivery to provide the desired bleaching.
