Abstract

627,003. Magnetrons. RAYTHEON MANUFACTURING CO. Nov. 13, 1945, No. 14885/48. Convention date, March 10, 1945. Divided out of 626,930. [Class 39 (i)] A magnetron of the multi-resonator type comprises a cathode with a central electron emissive section 3, Fig. 1, of relatively low heat capacity, end sections 16, 17, of relatively high heat capacity which extend into bores in magnetic polepieces 13, 14, and a highly heat conducting rod 25 carrying heat radiating fins 33 is attached to the lower end of the section 17. Alternate and intermediate anode segments are strapped together by members 4, 5, 6, 7, Figs. 1, 3. The polepieces 13, 14 are energized by an external magnet. The surfaces of the bores 22, 23 may be blackened so as to absorb heat more readily from the members 16, 17. The fins 33 may be cooled by blowing air against them. The fractional mode separation may be made greater than 1/(N/2 +1), as described in Specification 626,930. The Specification as open to inspection under Sect. 91 states that the anode segments need not be strapped. This subject-matter does not appear in the Specification as accepted.
