Abstract: 398,945. Gauge glasses. DROSNE, P. E., 35<bis>, Rue du Chateau, Asnieres, Seine, and UNION D'ELECTRICITE, 3, Rue de Messina, Paris, both in France. April 30, 1932, No. 12517. Convention date, Dec. 17, 1931. [Class 123 (i).] A gauge glass comprises a prismatic column through which a beam of light is passed, so that the difference in refraction through the parts above and below liquid level produces a horizontal displacement of the two bands of illumination on a screen. The gauge 1, Fig. 1, is placed between a straight line light source S<1>, S<1>1, S<11>1, and a screen E<2>, F<2>. Light passes through the upper part of the gauge without appreciable refraction, and forms an image S<1>4, S<1>6 on the screen, while light passing through the liquid in the lower part of the gauge forms a refracted image S<1>5' S<1>7 displaced horizontally from the upper image, so that the level of the liquid is clearly indicated. A scale G may be illuminated by a diffused light. A point source S<1>1 is placed near the plane of the liquid level 2 to avoid reflection or refraction at the plane of separation. In the construction shown in Fig. 4, two transparent plates 3, 4 are mounted in a housing 5 to enclose a prismatic column of liquid 6. A source of light emitting convergent pencils is employed, so that the point of convergence falls on the screen. The light may be placed in the focus of a parabolic mirror, the parallel rays obtained being passed through a lens to form a convergent pencil. In a modification, Fig. 11, the gauge is formed by four glass plates 11 .. 14, so that the enclosed double prism of liquid acts as a convergent lens. In another alternative, Fig. 9 (not shown), the glass plates bounding the liquid column mav be curved on their outer surfaces so that a true lens is obtained. In other forms, Figs. 12, 13, 14 (not shown), modifications of the mounting shown in Fig. 4 are described. In Fig. 14, a small circular core is employed, around which the mounting may be rotated to obtain the desired angular adjustment with respect to the source of light. In another modification, Fig. 15, the transparent plates 30, 31 are mounted in supports 44. 45 of an alloy having the same coefficient of expansion, pressed by springs 65 against the housing 43. Openings 66, 67 are provided in the supports 44, 45 for the passage of light.
