Abstract

14,926. Lovibond, J. W. Junc 21. Colorimeters.-In apparatus for determining the colour - thickness curves of translucent liquids, a single eyepiece f commands two substantially vertical sighting-tubes c', c<2>, in one of which c<1> standard colour-scales are adapted to be mounted, while below the other is mounted a scale-marked tube k closed by a transparent plate and containing the liquid under test. By the determination of the colours of various depths of the liquid in colour units, the data for plotting the curves are obtained. Specifications 3027/70, 12,867/86, and 3859/87 are referred to.
