Abstract
256,647. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Aug. 8, 1925, [Convention date]. Controlling; impeller blades. - The vanes of blowers and compressors have a series of holes or gaps c which produce an equalization of pressure and velocity in the individual passages of the impener. This equalization has the effect of lowering the pumping limit.
