Abstract

1,062,838. Changing signs. GATAG Ltd. Nov. 19, 1965 [Nov. 28, 1964], No. 49205/65. Heading G5C. An indicator comprises superposed transparent plates 4, each having recesses 5, the recesses in any one or more plate(s) being selectively filled with a coloured fluid to form a representation. The plates are backed by a translucent plate 8 and the representations may be illuminated by tubes 15 or by reflected light. The liquid may be ethyl alcohol, and may contain reflective or fluorescent components. The liquid is supplied by an electromagnetically operated pump 20 and overflows into containers 13. The supply tubes 9 each contain a magnetically actuated valve 11 should a representation need to be shown over a period of time. If the representations in all the plates are to be of the same colour a single supply tank 10 may be used.
