  With the aid of the compressed air reservoir you are able to conduct various soldering operations, requiring often great heat. Let us construct the following pulverizer: Into a bottle of the shape shown in the figure, put some petroleum, and introduce a glass tube that does not quite reach the bottom. Close with wax that no air can enter, and at the upper extremity of the tube let a fitting be embedded, a section of which is shown in the engraving. This fitting has three openings, two horizontals and one corresponding with the tube that is plugged into the petroleum. Adjust the india-rubber tube to the reservoir, and when the pressure is exercised on the surface of the liquid it will force the petroleum upwards through the tube, and thence it will be blown in a fine spray, which burns as if coming This pulverizer may serve also to disinfect rooms. You have only to replace the petroleum with an antiseptic liquid. |
