Abstract

891,920. Electric measuring instruments. VOCKENHUBER, K. Nov. 9, 1960 [Nov. 10, 1959], No. 38447/60. Drawings to Specification. Class 37. [Also in Group XL (b)] A photo-electric exposure meter comprises a moving coil meter having no control springs, the control being provided by a second winding connected to the battery which operates the photo-cell. This provides a constant restoring force and compensates for variations in the battery voltage.
