Abstract

448,072. Valve amplifying circuits; discharge apparatus. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Sept. 4, 1935, No. 24689. Convention date, Sept. 4, 1934. [Classes 39 (i) and 40 (v)] A magnetron with its anode split into sections numbering four or a multiple of four is used for the amplification of very short waves. As shown, the magnetron has an axial cathode and its cylindrical anode is split into four sections 1 ... 4. Two opposed sections 1, 2 are connected by leads to the secondary of a push-pull input transformer T1 fed by a source S, and are polarized at a low positive voltage by a battery U1. The other electrodes 3, 4 are used as output electrodes, being connected to a push-pull output transformer T2 and polarized at a high positive voltage by a battery U2. A fixed magnetic field is set up along the axis of the electrodes by means not shown, and is of such value that the input electrodes 1, 2 do not receive electrons, but cause the electron flow to the sections 3, 4 to increase and decrease alternately. Electrostatic symmetry of the anode sections can be obtained by appropriately extending the leads to two adjacent segments 1, 4.
