Abstract
30. Hewitt, J. M. Jan. 2. Centrifugal pumps; fans.-Multi-stage centrifugal pumps and fans, Figs. 1 and 3, are provided with conical bosses between the impellers g, g<1>, g', upon which are mounted helical diffuser blades so as to give the fluid a screw-like motion from one end of the pump or fan to the other. In this manner, shock and eddy currents are prevented. The pump may be used for air pumps for condensing engines, for compressors for air and other gases, and for vacuum pumps.
