Abstract
Abstract The present apparatus includes a vessel having at least one agitator that stirs and thereby agitates the contents. The bottom of the vessel is provided with a member adapted to agitate the contents and to inject substances into the vessel. Preferably the agitator in the bottom of the vessel generates a vortex motion in the contents of the vessel and a fluid may be injected into the vortex and mixed with the contents of the vessel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
93 words
Apparatus for treating substances which comprises a vessel, agitation means and means located adjacent the bottom of said vessel for injecting substances into the vessel and for agitating the contents thereof in the area of said injection in which the injection and agitation means comprise a nozzle rotatably mounted in the bottom of the vessel for injecting a spray of fluid into the vessel, said nozzle having at least one agitator mounted thereon for agitating the contents of the vessel to generate a vortex motion therein and drive means for rotating said nozzle.
Claim 2
Dependent Claim
93 words
Apparatus for treating substances which comprises a vessel, agitation means and means located adjacent the bottom of said vessel for injecting substances into the vessel and for agitating the contents thereof in the area of said injection in which the injection and agitation means comprise a nozzle rotatably mounted in the bottom of the vessel for injecting a spray of fluid into the vessel, said nozzle having at least one agitator mounted thereon for agitating the contents of the vessel to generate a vortex motion therein and drive means for rotating said nozzle.
Claim 3
Dependent Claim
38 words
The structure specified in claim 1 in which the injection and agitation means located adjacent the bottom of the vessel extend inwardly through the bottoM of the vessel to a position above one end of said agitation means.
Claim 4
Dependent Claim
22 words
The structure specified in claim 1 in which the agitator extends inwardly into the vessel beyond the open end of the nozzle.
Claim 5
Dependent Claim
20 words
The structure specified in claim 1 in which at least one agitator is rotatably mounted to revolve about said nozzle.
Claim 6
Dependent Claim
31 words
The structure specified in claim 1 in which a baffle plate is mounted on the nozzle above the opening therein, and at least one agitator is mounted on said baffle plate.
Claim 7
Dependent Claim
76 words
Apparatus for treating substances which comprises a vessel, at least one agitator mounted eccentrically in said vessel, means for revolving said agitator about the center of the vessel and for simultaneously rotating said agitator about its own axis, agitation means located adjacent the bottom of said vessel and injection means for injecting a substance into the vessel adjacent the bottom thereof, said agitation means and injection means being located inside the path traveled by said agitator.
Claim 8
Dependent Claim
76 words
Apparatus for treating substances which comprises a vessel, at least one agitator mounted eccentrically in said vessel, means for revolving said agitator about the center of the vessel and for simultaneously rotating said agitator about its own axis, agitation means located adjacent the bottom of said vessel and injection means for injecting a substance into the vessel adjacent the bottom thereof, said agitation means and injection means being located inside the path traveled by said agitator.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
25 words
The structure specified in claim 7 in which the agitation means are rotatably mounted adjacent the bottom of the vessel to revolve about said nozzle.
Claim 11
Dependent Claim
45 words
The structure specified in claim 8 in which the agitation means comprise a baffle plate mounted on the nozzle above the opening therein and in which the agitation means are mounted on said baffle to generate a vortex motion in the substance to be treated.
Claim 12
Dependent Claim
46 words
The structure specified in claim 7 in which the nozzle is rotatably mounted in said bushing and in which the agitation means are mounted on said nozzle to generate a vortex motion in the substance to be treated and which includes means for rotating said nozzle.
Claim 13
Dependent Claim
49 words
The structure specifed in claim 7 in which the bushing is rotatably mounted in the bottom of said vessel and in which the agitation means are mounted on said bushing to generate a vortex motion in the substance to be treated and which includes means for rotating said bushing.
