Abstract

1,260,302. Extrusion; drawing. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 4 March, 1969 [13 March, 1968], No. 11571/69. Divided out of 1,260,301. Heading B3P. The Specification is substantially identica<SP>1</SP> with that of Specification 1,260,301, but the claims relate to the use of a billet in a hydrostatic extrusion process which has a leading end of smaller diameter than the main part of the billet but of larger diameter than the bore of the die.
