Abstract
1,267,688. Liquid level indicators. WOOD BROS. GLASS CO. Ltd. Aug.7, 1970 [Aug. 8, 1969], No.39768/69. Heading G1H. Volumetric vessels such as flasks are provided with a dark area, e.g. of a vitreous enamel, not more than 1 m.m. below the graduation line to permit the meniscus of the measured volume of liquid to be viewed more easily against a white background.
