8746. Auger, G. April 21. Incandescent gas lamps. - Filaments for incandescent lamps, formed by an extrusion press C, are calcined by an oxyhydrogen or like annular burner A arranged beneath the press and provided on its underside with inclined apertures, so that the flame jets converge to a point, the filaments passing centrally through the burner. The extrusion aperture B of the press may be formed in a detachable piece, so that different apertures may be employed.
