Abstract

739,092. Magnetrons. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 2, 1954 [Feb. 7, 1953], No. 3517/53. Class 39 (1). The helical cathode heater 9 is fed with D.C. of such polarity that the forces on it generated by the non-uniformity of the magnetic field, which usually has a slight minimum on the axis due to the apertures 5, 6 in the polepieces, tend to stabilize the heater in the axial position.
