Abstract

1,055,990. Colour comparators. NIPPON KONSANTO SHASHIN KOGYO KABUSfflKI KAISHA. Dec.19, 1963 [Dec. 25, 1962], No. 50223/63. Heading G2J. Light from source 2 passes through a colour filter 5 and is reflected by the mirror 6 through apertures 8 into the window 3. Simultaneously light from an enlarger passes through a colour negative then through the opening 10 and is reflected by T-shaped mirrors 9 into the window 3 where the two coloured lights are compared.
