Abstract

137,274. Harter, E. Dec. 30, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Casings.-In order to distribute the fluid evenly over the vanes e of a centrifugal fan, a number of partitions or crowns f are arranged in the inlet, being placed perpendicularly and concentrically to the shaft g.
