532,863. Washing air. ARMSTRONG, J. J. V. (Wittemeier, H.). Feb. 16, 1939, No. 5054. [Class 55 (ii)] The air is fed through a pipe 2, and is distributed by a guide member 3 fitted with vanes 4 and partly immersed in a liquid bath 5. The air panes through a grating 9 to damp circular motion, a filter 8, a dead space 10, and escapes through a pipe 12. The vanes are held between guide plates 3a, 3b, the latter extending substantially across the liquid bath. In a modification the guide is conical in formation, and is placed above the surface of the liquid. U.S.A. Specification 2,004,467 is referred to.
