Abstract

798,060. Waveguide accessories. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 4, 1955 [Jan. 14, 1954], No. 1079/54. Class 40 (8). [Also in Group XL (c)] A variable attenuator consists of a block of ferrite 10 substantially filling the whole crosssection of a waveguide, the permeability and hence the attenuation, being controlled by a solenoid 14. Specification 791,431, [Group XL (c)], is referred to.
