Title: The Innovations of Adolf Seiler
Introduction
Adolf Seiler is a notable inventor based in Munich, Germany. He has made significant contributions to the field of photography through his innovative processes. With a total of 2 patents, Seiler has focused on enhancing the efficiency and effectiveness of photographic bleach-fix baths.
Latest Patents
Seiler's latest patents include a process for the regeneration of photographic bleach-fix baths. This process involves rejuvenating baths containing iron-III-complexes of aminopolyacetic acids as oxidizing agents by reducing the iron-III-complexes with a reducing agent other than iron. Following this, the baths are desilvered through treatment with iron. Another significant patent is for the process of desilvering used bleach fix baths. In this method, photographic bleach fix baths are desilvered by electrolysis in a cell where the cathode and anode chambers are separated by a diaphragm, ensuring the exclusion of air. The bleach fix bath is removed from the cell before the potential is switched off, and to increase the current yield, the bleaching agent can be reduced prior to electrolysis, for example, by adding sodium dithionite.
