Abstract

816,872. Milling. ELECTRIC & MUSICAL INDUSTRIES Ltd. Sept. 22, 1955 [Oct. 13, 1954], No. 29445/54. Drawings to. Specification. Class 83 (3). [Also in Group XXXVIII] A method of milling an aircraft wing consists in using a punched record tape (see Group XXXVIII) to produce a model wing, testing the model, and finally scaling-up the reproduction from the tape to produce the full size wing.
