Abstract

629,436. Making hollow-ware and turbine blades. BIRMINGHAM SMALL ARMS CO., Ltd., and LAWRENCE, P. H. Sept. 17, 1947, No. 25354. [Class 83 (ii)] [Also in Group XXVI] The method of making hollow metal articles described in Specification 623,041 is modified by the formation of holes 1 through the solid former 3, the inner surfaces of which holes become interdiffused with the diffusing metal and after the dissolution of the former, leave tubular elements 5 strutting the terminating -surfaces of the article. Specifications 516,260, 572,703, 574,737, [all in Group II], and U.S.A. Specification 1,853,369 are referred to.
