Abstract

703,375. Velocity-modulated tubes. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Feb. 28, 1948 [April 20, 1939], No. 21405/51. Drawings to Specification. Class 39(1) The subject-matter, a reflex tube in which the reflected beam passes through a portion of the resonator separate from that part containing the incident beam, is identical with Figs. 1 and 2 of Specification 545,146, but the claims differ. Specifications 517,264, 523,712, 530,785, 703,324 and 703,325 also are referred to.
