Abstract
A depicted embodiment of the apparatus comprises a housing having a chamber therewithin and a pair of ports opening into the chamber. One port admits an energized gas, and the other admits a particulate powder, into the chamber. Tubes conduct the powder through the chamber, isolated from the energized gas, to exit ends of the tubes which have convergent/divergent ejector nozzles circumjacent thereto. The ejector nozzles discharge the gas therethrough in fine streams, to draw powder from the tube exit ends for conveyance with the gas streams, and direct the streams of gas and powder to adjacent and collinear diffusers for dispersion of the gas-borne powder from the apparatus.
