Abstract

1,088,967. Liquid level indicator. SOC. ANON. HERCULE. June 24, 1966 [June 24, 1965; July 22, 1965], No. 28532/66. Heading G1H. In a liquid level indicator with a multi-colour indication equipped with at least one window 1 of rectangular parallel piped form a longitudinal groove on the internal face of the window is formed as a dihedron 2, 3, the common edge of which is parallel to the longitudinal direction and at least one of the lateral faces of the window has a coloured coating 4. The coating 4 may be phosphorescent and heat resistant paint or enamel or a coloured material thermatically sealed transparent tubes containing a photo-laminescent substance and a small quantity of radioactive material may be located in a recess formed along one of the window lateral faces.
