Abstract
1,248,064. Colour mixing apparatus. J. FILLACIER and A. LEMONNIER. Dec. 4, 1968 [Dec. 7, 1967], No. 57592/68. Heading G2J. A colour comparator comprises a turn-table in combination with a code and a plurality of coloured discs, the discs being locked on the turn-table in an overlapping relationship determined by the code such that when the turn-table revolves a given colour is seen determined by the exposed areas of the overlapping discs. The discs may either be in the form of different sectors Fig. 7 or may be completely circular and have a radial slit extending to their circumference so that discs could be interleaved to give different areas of overlap. Two kinds of disc are provided. One series of pure colours and a second of shades of those colours to white. Darkening of tone is provided by a black disc 12 Fig. 4 which is notched and is cut into a series of symmetrical areas of concentric circles. Thus when disc 12 is placed over a colour disc 9, or a set of overlapping discs on the turn-table rings of colour tones will be seen, the inner most of which will be black. To help identify a desired one a pointer is fixed to the turn-table. The single black disc can be replaced by a plurality; viz four for each notch, e.g. a 4, Fig. 4. The colour discs, shades and black discs are coded, so that for a given code set discs will be overlapped to a specified degree with a certain black disc to give a specified colour, see Fig. 8 (not shown).
