An Improved Method and Apparatus for Mixing Oily Medicinal Substances with Liquids Supplied to the Sprayers of Inhaling Apparatus, I, Dr. Anton Bulling, of Karlstrasse 21/1, Munich, in the Empire of Ger¬ many, Physician, do hereby declare the nature of this invention to he as follows;: This invention relates to an improved method and apparatus for mixing 5 oily medicinal substances suitable for inhalation such as larch oil and the like, with the liquid supplied to the sprayers of inhaling apparatus. For this purpose a current of compressed air is directed on to the surface of the liquid to be inhaled, that is to say, on to the medicinal oily substance float¬ ing on the surface of the said liquid. The air coming into contact with the 10 oily substance causes part of the latter to evaporate with intensity and to satu¬ rate the air. At the same time the powerful air current forces the oily sub¬ stance underneath the surface of the liquid and conveys it, intimately mixed with the latter, to the sprayer. One form of the apparatus for performing this method comprises a com- 15 pressed air sprayer in which a current of air issuing from a nozzle sucks liquid through tubes. For increasing the sprayer action a number of nozzles, for instance four, are provided. The air is forced through a concentric ring or tube with holes in its under surface directly onto the surface of the water, in order to come into contact with, and increase the evaporation of, the oily medicinal 20 substance floating on the latter, but more particularly in order to mix the said oily substance with the water so that it is carried with the latter through the tubes of the central sprayer which have their orifices below the water surface. The oily substance is thus converted into spray that is to say, mixed with 25 air, together with the water. The concentric ring or tube referred to is preferably arranged on floats in order to maintain it at a constant distance from the water level and thus to render the action uniform.
