Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 188 words
An apparatus for introducing and mixing liquids of various viscosities comprising: a. a mixing head having a mixing chamber, b. mixing means in said mixing chamber, c. a first inlet means for said mixing chamber for injecting a high viscosity first liquid into said mixing chamber on demand including first controlled inlet valve means, d. a second inlet means for said mixing chamber for injecting an atomized low viscosity second liquid into said mixing chamber on demand, e. said second inlet means including an atomizing chamber immediately adjacent said mixing chamber and connected directly thereto by an inlet orifice in the wall of said mixing chamber, f. second controlled inlet valve means in said atomizing chamber for closing said inlet orifice, g. a plurality of inlet orifices radialLy disposed in the wall of said atomizing chamber selectively controllable for injecting said second liquid into said atomizing chamber on demand including a controlled valve member for each of said inlet orifices, h. gas inlet means in the wall of said atomizing chamber for injecting compressed gas into said atomizing chamber for atomizing said second liquid in said atomizing chamber.
Claim 2
Independent Claim 188 words
An apparatus for introducing and mixing liquids of various viscosities comprising: a. a mixing head having a mixing chamber, b. mixing means in said mixing chamber, c. a first inlet means for said mixing chamber for injecting a high viscosity first liquid into said mixing chamber on demand including first controlled inlet valve means, d. a second inlet means for said mixing chamber for injecting an atomized low viscosity second liquid into said mixing chamber on demand, e. said second inlet means including an atomizing chamber immediately adjacent said mixing chamber and connected directly thereto by an inlet orifice in the wall of said mixing chamber, f. second controlled inlet valve means in said atomizing chamber for closing said inlet orifice, g. a plurality of inlet orifices radialLy disposed in the wall of said atomizing chamber selectively controllable for injecting said second liquid into said atomizing chamber on demand including a controlled valve member for each of said inlet orifices, h. gas inlet means in the wall of said atomizing chamber for injecting compressed gas into said atomizing chamber for atomizing said second liquid in said atomizing chamber.
Claim 3
Dependent Claim 36 words
