Abstract

426,517. Static contact rectifiers. TOMLINSON, A. V., 65, Victoria Street, London.-(Hartmann & Braun Akt.-Ges. ; Frankfort-on-Main, Germany) Feb. 8, 1934, No. 4214. [Class 37] A surface contact rectifier is constructed of elements having temperature coefficients of resistance of opposite sign so that the total resistance of the rectifier as a whole remains substantially constant and independent of temperature. In an example, elements utilizing copper-oxide with a negative coefficient are combined with elements utilizing selenium which has a positive coefficient.
