Abstract

26,289. Westinghouse Metallfaden Gl³hlampenfabrik Ges. Nov. 20, 1911, [Convention date]. Filaments of metal are formed into narrow helices, of which the inner diameter approximates to or is less than the thickness of the filaments. Such helices are made by spinning the filament on temporary cores of silk or silver, for instance in machines similar to those used for covering wires with silk. They do not require supports.
