SU24401A1 - Dual gauge glass - Google Patents

Description

Patent No. 8493 describes a Klinger-type dual gauge glass device, which consists in the fact that in order to better illuminate the meniscus with a light source behind the glass, rear glass is used, elongated in its lower part with respect to the front one and equipped with the same cylindrical internal glass undercut. In addition, in addition to these basic glasses of rectangular cross section, convex glass is also used, which is located at the front and intended to increase the visibility of the same meniscus.

The present invention is a modification of the aforesaid device and consists in the fact that a glass is placed inside the glass;

In FIG. 1 shows a longitudinal section of a gauge glass; FIG. 2 is a front view and FIG. 3 shows a section along the line / - // in FIG. one.

The cavity between the glasses 3 vi 4, which BBtJpxy communicates with the steam one, and below with water space, is placed a spherical or some other form of a float (Fig. 1), designed to amplify the light and color signals especially at its highest and lowest position This amplification of light signals is achieved by reflecting light rays from the surface of the float and may be of importance if, for example, the water level in the glass is lowered or raised so that

became invisible; then, in the absence of a float, it will be difficult to determine whether the water fills the entire gauge glass, or it does not exist at all, since in both cases the entirely visible inner cavity of the glass appears to be uniformly filled. Such a situation can easily lead to a delusion, especially if it is not known whether the level in the glass preceded this circumstance or whether there was a decrease in the level. With the same float /, the latter, being on the surface of the water and following its ypOBiHeM at the lowest position, stops at stop 2 and, reflecting for example the red rays, signals a lack of water; otherwise, i.e. when the water level in the glass rises, it can occupy the highest position and, delayed by the stop 5 from further lifting, reflects rays of a different color, thus signaling an excess amount of water.

The subject matter of the invention.

Modification of Klinger's dual gauge glass, characterized in patent No. 8493, characterized in that a float is placed inside the glass of a prismatic, cylindrical or spherical shape, intended to be amplified by reflecting light rays, light and color signals, especially at the highest and lowest position of the float.
