Abstract

3929. Brandenberger, J. E. March 22, 1911, [Convention date]. Drawings to Specification. Apparatus for making films.-A hopper with movable lips which can be brought together or moved apart whenever desired is used in the process of producing films by passing cellulose solutions directly into a coagulating-bath. In one construction the walls of the hopper are oblique, and in a second form the outer face of the bottom of the hopper is horizontal, sliding pieces worked by gearing in both cases serving to regulate the width of the slit. Specifications 8917/85, 3369/89, 19,896/89, 11,945/90, 5504/93, 4445/98, and 28,538/08, [all in Class 98, Photography], and 28,613/96 are referred to.
