Abstract

285,848. Legendre, R. A. Feb. 23, 1927, Colorimeters.-In a colorimeter of the type in which the sighting system permits of two separate sighting lines being obtained, the tank or reservoir systems comprises two units each having three tanks with transparent walls The tanks are so constructed that the thicknesses of liquid traversed by the lines of sight remains constant for one tank as it is moved across the line of sight and varies in opposite directions for the second and third tanks, the sum of the thicknesses of the last two remaining constant. The thicknesses of liquid traversed in the two units are the same at each instant. In one example, the units consist of a tank a<100> of uniform thickness, a second tank a<10> and a third tank a<1>, these two latter tanks being in the form of right-angled triangular prisms oppositely arranged. The two units are placed together and illuminated by means from a source i reflected from mirrors l<1> l<2>; observation being made by means of an eyepiece o, and a Pulfrich prism p. In another example, the units comprise tanks having cylindrical vertical transparent walls, the tanks of greatest and least diameter being coaxial and the third eccentric. The tanks are illuminated through the hollow axis upon which they rotate and are viewed in a similar manner to that of the first example.
