Abstract

778,641. Permanent magnets. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Nov. 15, 1955 [Nov. 18, 1954], No. 32648/55. Class 35. [Also in Group XL (a)] A uniform magnetic flux for a travelling- wave tube is derived from a generally U- shaped magnet A having an air-gap between poles 2, 3 surrounded by a cylindrical magnet B. The cylindrical magnet may have a plain cylindrical outer or inner surface and may be built up of a plurality of bar magnets. Suitable sizes and materials are mentioned. Specification 770,133 is referred to.
