Abstract

978,197. R.F. couplings. RADYNE Ltd. July 4, 1962 [July 5, 1961], No. 24322/61. Heading H4A. Microwave dielectric heating apparatus comprises a flared oven cavity 3, a hinged lid 1 for placing a dish 5 containing the food to be heated, a magnetron 6, a probe 7, a cylindrical waveguide matching section 8, a launching cone 9 and a sliding contact 10 to permit adjustment of voltage standing wave ratio (V.S.W.R.) within the matching section. Dimensions are quoted. Empirically determined angles of flare of cavity 3 and cone 9 for a particular apparatus enables more uniform heating, and immunity of the magnetism to damage because of low V.S.W.R., to be achieved.
