9486. Koch, A. April 23, 1912, [Convention date]. Radiations, effecting reactions by.-Natural water is treated for the purpose of preventing the formation of scale when used in steamboilers by subjecting it to sunlight or artificial light in which blue predominates, and in a condensed state. The water flows over a glass plate, and a reflector for blue light is placed behind, and the water may be also treated with light from a screen placed in front. In the apparatus shown in Fig. 3, water flows over a vertical or inclined glass plate a with a screen c for transmitting blue light in front and a reflector b at the back. To increase the effect, the glass plate a or the reflector b, or both, are provided with devices .for condensing the light, such as lenses, prisms, or concave mirrors. The Specification as open to inspection under Section 91 (3)(a) comprises also a modification in which water is treated in a vessel i, Fig. 5 (Cancelled), having a reflecting inner surface q, with light from an electric lamp m of any preferred kind arranged in a protective casing p. This subject-matter does not appear in the Specification as accepted.
