Abstract

Abstract There is provided an apparatus for bringing into contact liquids at least one of which is viscous, the apparatus consisting essentially of a tubular container, a first nozzle from introducing a liquid in the upper portion of the container, at least one other nozzle lower than the first nozzle for introducing a different liquid, the tubular container being closeable at the tap thereof and downward from said other nozzle being constricted breast shaped to form a discharge opening, said other nozzles are preferably of polished steel, said other nozzles consist essentially of at least one tangential spray means arranged in at least one row, said other nozzles being slightly above said constriction and being directed in the direction of the upper closeable device or said first nozzle and wherein the discharge opening can discharge into another container which is permanently or detachably connected to the tubular container, said further container can be provided with means for establishing reduced pressure or superatmospheric pressure.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 155 words
An apparatus for bringing into contact liquids at least one of which is viscous, the apparatus consisting essentially of a tubular container, a first spray nozzle means adapted for the introduction of a liquid in the upper portion of the container, at least one other nozzle means lower than the first spray nozzle means for introducing a different liquid, the tubular container being closeable at the top thereof and downwardly from said other nozzle means being constricted in a breast shaped manner to form a discharge opening, said constriction being in the form of a flat S curve going from the wall of the tubular container to the discharge opening, said other nozzle means consisting essentially of at least one tangential spray means arranged in at lease one row, said other nozzle means being slightly above said constriction and being directed in the direction of the upper closeable device or said first spray nozzle means.
Claim 2
Independent Claim 155 words
An apparatus for bringing into contact liquids at least one of which is viscous, the apparatus consisting essentially of a tubular container, a first spray nozzle means adapted for the introduction of a liquid in the upper portion of the container, at least one other nozzle means lower than the first spray nozzle means for introducing a different liquid, the tubular container being closeable at the top thereof and downwardly from said other nozzle means being constricted in a breast shaped manner to form a discharge opening, said constriction being in the form of a flat S curve going from the wall of the tubular container to the discharge opening, said other nozzle means consisting essentially of at least one tangential spray means arranged in at lease one row, said other nozzle means being slightly above said constriction and being directed in the direction of the upper closeable device or said first spray nozzle means.
Claim 3
Dependent Claim 16 words
An apparatus according to claim 1 wherein said other nozzle means are made of polished steel.
Claim 4
Dependent Claim 41 words
An apparatus according to claim 1 including a second container connected to said tubular container, means for conveying material from said discharge opening in said tubular container to said second container and means in said second container for regulating the pressure.
Claim 5
Dependent Claim 17 words
An apparatus according to claim 1 wherein said other nozzle means are located directly above said constriction.
