Abstract

1300802 Extruding WESTERN ELECTRIC CO Inc 27 Jan 1970 [28 Jan 1969] 21719/72 Divided out of 1300801 Heading B3P The description is substantially identical with Specification 1,300,801 but the claims relate to a method of extrusion wherein the bar is advanced to the extrusion die through regions of pressurized fluid whose pressures increase in the direction of advance, extrusion taking place in a region of high pressure.
