Abstract

362,959. Acoustic wave filters. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and OLIVER, D. A., of General Electric Co., Wembley, Middlesex. Sept. 3, 1930, No. 26271. [Class 13.] An acoustic phase-shifting device consists of a main conduit 10 with apertures 11, 12 leading to chambers 14, 15, connected by a conduit 16. An aperture 13 leads to the open air. Such a device gives a phase shift of 180‹.
