Atomizing and mixing apparatus

A device for intermixing a carrier gas and a first substance to be carried thereby so as to impregnate one with the other, and for introducing a second substance into said carrier gas and first substance mixture, comprising:

• A elongated hollow tubular member in which said hollow tubular member is constricted intermediate its ends;
• means adjacent the first end of said tubular member so adapted to admit gas into said tubular member;
• control means adjustably fastened within said first end so as to allow adjustable positioning of one end of said control means with respect to the constricted portion to the tubular member;
• First conduit means entering said tubular member adjacent the second end of said tubular member, said first conduit means terminating in a substance dispersal surface adjacent the constricted portion of the tubular member;
• A channel circumferentially surrounding the exterior of said tubular member;
• second conduit means interconnecting said channel and the interior of said tubular member at the constriction thereof;
• said second conduit means connected to said channel suitable to supply a substance thereto;
• Means adjacent the said second end of said elongated member for extracting gases therefrom and for drawing, as a function of said extraction, other gases into said member through the gas admitting means adjacent said first end of said tubular member;
• and gas supply means for said gas admitting means;
• First substance supply means for first conduit;
• and second substance supply means for said second conduit.
