Abstract

937,246. Photo-electric colour determinations. C. H. A. GAMAIN. Nov. 25, 1960 [Nov. 26, 1959], No. 40680/60. Class 40 (3). [Also in Group XXXV] A photo colorimeter comprises two cells 41, 42 having selective screens, one, for example, permitting the passage of a red-yellow band of 5650-7000 Š and the other a green-violet band of 4000-5600 Š. The cells are parallel connected to adjusting resistors and capacitors 45- 48 and to coils 43, 44 of a galvanometer which indicates by a pointer 49 and scale 50 the balance of the apparatus for a selected colour of light.
