Abstract
172,280. Kino-Film Co., and M³nch, C. Dec. 3, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Films and papers; sensitive coatings, preparing. -A process is described for coating films and paper with a gelatine-bromide emulsion hawing a minimum amount of gelatine and a maximum amount of silver bromide. Thin coatings of the emulsion are used. In applying the emulsion, a coating roller is used, and special cooling- apparatus is not necessary. The coating- machine can be run at a slower speed (2.5 metres per minute), and a shorter length (about 25 metres) for the drying-apparatus is sufficient.
