Abstract

647,762. Dielectric heating. MURPHY RADIO, Ltd., and TOMES, S. R. July 23, 1946, No. 21949. [Class 39(iii)] A flexible electrode for H.F. heating designed to eliminate " gapping " between pressure electrodes comprises a flexible back " comb " 1 of metal, pressure being applied to the ends of the teeth in a direction along their length by springs 4. Rubber or like resilient means may be employed in place of the springs in the holder 3.
