Abstract

525,397. Calculating-apparatus. STANDARD TELEPHONES & CABLES, Ltd. (Kozma, L., and Kruithof, J.). Nov. 21, 1938, No. 27540/39. Divided out of 525,330. Drawings to Specification. [Class 106 (i)] An electrically-operated calculating-apparatus comprises two similar calculating units, means for directing a calculation problem simultaneously to both of said units in the same manner and means for comparing the solutions obtained by said units for the purpose of checking the calculations before transmitting the correct result. The description in the Specification is identical to that in Specification 525,330. Specifications 525,329. 525,396 and 525,398 also are referred to.
