Abstract

1,225,855. Magnetrons. MATSUSHITA ELECTRONICS CORP. 26 Aug., 1968 [7 Sept., 1967], No. 40721/68. Heading HID In a magnetron assembly which dispenses with forced cooling, Figs. 1 and 2, the anode block 2 of the magnetron 1 is mounted through an aluminium slab 3 having arrays of aluminium cooling fins 8 clamped to each end, the upper surface of the block supporting the solenoid or permanent magnet 5 and yoke 6. The fin arrays rise above the top of the magnetic system, to protect the latter; the anode block may be secured within block 3 by soldering or by the use of a thermally conductive resin. Dimension and weight data are included.
