Abstract
Abstract Two or more vessels are provided each having therein a different liquid components which is to be admixed with the liquid components in the other vessels. A pump is located at a level lower than the vessels and a mixing chamber is located between the vessels and the pump. Conduits connect the mixing chamber with the respective vessels and a single conduit connects the mixing chamber with the suction side of the pump. Throttling means is provided in each of the conduits connecting the vessels with the mixing chamber.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
123 words
In a mixing apparatus for liquids, in combination, at least a first and a second vessel each containing a different liquid component; a pump locaTed on a level different from said vessels; a mixing chamber on a level below said vessels; a pair of first conduits each connecting one of said vessels with said mixing chamber for supplying the respective liquid component to the latter; a second conduit connecting said mixing chamber with the suction side of said pump for supplying the mixed liquid components thereto; adjustable throttling means in each of said first conduits; and regulating means for maintaining the level of liquid components in said vessels substantially equal, so as to assure a substantially uniform pressure head in said first conduits.
Claim 2
Dependent Claim
123 words
In a mixing apparatus for liquids, in combination, at least a first and a second vessel each containing a different liquid component; a pump locaTed on a level different from said vessels; a mixing chamber on a level below said vessels; a pair of first conduits each connecting one of said vessels with said mixing chamber for supplying the respective liquid component to the latter; a second conduit connecting said mixing chamber with the suction side of said pump for supplying the mixed liquid components thereto; adjustable throttling means in each of said first conduits; and regulating means for maintaining the level of liquid components in said vessels substantially equal, so as to assure a substantially uniform pressure head in said first conduits.
Claim 3
Dependent Claim
31 words
In a mixing apparatus as defined in claim 1, wherein said first conduits are at least in part vertical; and wherein said throttling means are provided in the respective vertical parts.
Claim 4
Dependent Claim
44 words
In a mixing apparatus as defined in claim 1; further comprising inlets for liquid component to the respective vessels; shut-off valve means associated with one of said inlets; and wherein said regulating means is associated with and controls operation of said shut-off valve means.
