US Patent 1,596,086, granted 17 August 1926 to Emil Elsaesser and August Hartmann of Barmen-Langerfeld, Germany, and assigned to American Bemberg Corporation. It describes a stretch-spinning process and apparatus for artificial silk (rayon). The precipitating liquid flows against the fibre while it is partly hardened, then flows in the same direction as the fibre. Three apparatus designs are shown in drawings: a cylindrical jacket with an internal cone, a conical vessel without a jacket, and a cylinder with a short conical base. The text includes five claims.
