Excerpt from Tests of a Liquid Air Plant, Vol. 21 The air for use in the compressor is ordinarily taken from the atmosphere above the laboratory building and drawn through a low pressure purifier consisting of a metallic can 15 in. In diam eter by 36 ih. In height, containing trays on which lime is spread. Owing to the small diameter of the air inlet, (one inch), and to a tendency of the lime to cake in the trays, this purifier has been found to be unsatisfactory, as it caused unnecessary suction on the compressor, thereby lowering the efficiency and also at times permitting lime dust to be drawn into the cylinder. During these tests this purifier was out out and the air taken from the inside of the building. When the purifier was used again later, it was found that the greater part of the impurities, carbon dioxide and water, was removed by the high pressure purifier. From the high pressure cylinder the air is conducted to the air receiver, B, (fig. Through i-ih. Extra heavy iron pipe sub merged in a channel of running water.

The tube was tested by the maker to 4000 lh. Per sq. In. And may be used con tinuously at a working pressure of 8000 lh. Per sq. Ih. The action of the receiver in maintaining a constant pressure of the liquefier was highly satisfactory. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
