Abstract

1306907 Heating resistors DANFOSS A/S 19 July 1971 [14 Aug 1970] 33853/71 Heading H5H A P.T.C. heating resistor is immersed in liquid to raise its power output. As shown P.T.C. resistor 1 is mounted in a casing 3 filled with oil, the casing being secured to the underside of a hot plate 8. A sheet metal plate 10 secured to one wall of casing 3 deflects to compensate for changes in oil volume.
