| Popis: | ALFRED WEINGARTEN, citizen of Poland, but resident of Berlin, is the inventor and patentee (U.S. Patent No. 1564161-Dec. 1, 1925) of a new and apparently quite practical process for the production of motion picture positives in quantity. In Herr Weingarten's film no silver compounds arc used, resulting in a considerable saving in the cost of raw stock. |
