Abstract

704,248. Electric analogue calculating systems. COOK, P. F. Feb. 15, 1952 [Nov. 15, 1950], No. 27986/50. Class 37 [Also in Group XXXVIII] Apparatus for measuring the quantity of fluid in the tanks of aircraft comprises a multiplication network (Fig. 6), wherein an input voltage Es energises a potentiometer 82 in series with a potentiometer 80 ; a potentiometer variable resistance 81 being connected across the input to the slider of potentiometer 82. Potentiometer 80 is graded in accordance with a law y = f (A) and varied by a shaft 83 while potentiometers 81 and 82 are respectively graded according to the laws y = f (B) and y = #2f(B), and ganged for variation by shaft 84. An output voltage Eo is developed on the slider of potentiometer 80 and it is shown that
