Abstract

623,380. Distant current and voltage measurements. STANDARD TELEPHONES & CABLES, Ltd., McWHIRTER, E. M. S., DUNN, R. H., and LENNOX, P. W. Feb. 5, 1946, No. 3618. Drawings to Specification. [Class 37] [Also in Group XXXVIII] In measuring equipment, a comparison between reference and variable quantities is expressed as a percentage by means of automatically set coarse and fine potentiometers which display the percentage by hundreds, tens and units digits. The invention is described with reference to a system identical with that described in the preceding abridgment. Specifications 555,999 and 621,384, '[both in Group XXXVIII], are referred to.
