Abstract

541,761. Electrical calculating apparatus. CONTRAVES AKT.-GES. June 6, 1940, No. 9937. Convention date, June 10, 1939. Addition to 520,228. [Class 40 (i)] [Also in Group XIX] The electrical calculating apparatus of the parent Specification is modified by arranging that the various networks, which are adjusted in accordance with the values of the respective variables, are located at separate positions at which the values are originally determined, the networks being interconnected by transmission lines the impedance of which matches the impedance of the networks.
