Abstract

915,322. Turbidometers. GRAVINER MANUFACTURING CO. Ltd. Feb. 27, 1961 [March 1, 1960], No. 7058/61. Divided out of 915,321. Drawings to Specification. Class 97 (3). [Also in Group XL (b)] The subject-matter of this Specification is substantially the same as that described in Specification 915,321, but the claims relate to an adjustable mirror for equalizing the output of the two photo-cells for zero-setting purposes.
