Abstract

871,382. Waveguides. GENERAL ELECTRIC CO. Ltd. July 20, 1959 [Aug. 1, 1958], No. 24963/58. Drawings to Specification. Class 40(8) [Also in Group XXII] The description is substantially the same as in Specification 871,383 but the claims relate to a method of manufacturing a waveguide structure. Specification 871,381 also is referred to.
