Total Claims: 10
Claim 1
Independent Claim
283 words
AN APPARATUS FOR USE IN AUTOMATICALLY DISSOLVING FIRST AND SECOND COMPOUNDS IN A FIRST MOVING STREAM OF A LIQUID IN WHICH THEY ARE SOLUBLE TO PROVIDE A SECOND MOVING STREAM OF A SOLUTION IN WHICH SAID FIRST AND SECOND COMPOUNDS ARE DISSOLVED IN A WEIGHT RATIO THAT IS PROPORTIONAL TO FIRST AND SECOND WEIGHTS OF SAID FIRST AND SECOND COMPOUNDS, SAID APPARATUS INCLUDING: A. FIRST MEANS FOR DEFINING A FIRST MOVING STREAM OF SAID LIQUID OF SUBSTANTIALLY CONSTANT VELOCITY; AND B. ELONGATE BALANCE BEAM MEANS PIVOTALLY SUPPORTED BY A FULCRUM MEANS INTERMEDIATE THE ENDS THEREOF AND HAVING FIRST AND SECOND ENDS THAT INITIALLY SUPPORT FIRST AND SECOND CONTAINERS HAVING PERFORATE LOWER ENDS HOLDING FIRST AND SECOND WEIGHTS OF SAID FIRST AND SECOND COMPOUNDS RESPECTIVELY IN SAID FIRST STREAM IN SUCH RELATIVE VERTICAL POSITIONS THAT SAID FIRST STREAM CONTACTS EQUAL SURFACES OF SAID FIRST AND SECOND COMPOUNDS THEREOF, WITH SAID BALANCE BEAM MEANS MOVING THE ONE OF SAID CONTAINERS HOLDING THE WEIGHT OF SAID ONE COMPOUND THAT DISSOLVES MOST RAPIDLY UPWARDLY TO EXPOSE LESS OF SAID SURFACE THEREOF TO SAID FIRST STREAM AND LOWERING THE OTHER OF SAID CONTAINERS THAT HOLDS THE WEIGHT OF SAID OTHER COMPOUND FURTHER INTO SAID FIRST STREAM TO EXPOSE MORE OF SAID SURFACE THEREOF TO SAID FIRST STREAM UNTIL SAID WEIGHT OF SAID OTHER COMPOUND HAS BEEN SO DECREASED BY DISSOLVING IN SAID FIRST STREAM THAT IT IS LIGHTER THAN THE WEIGHT OF THE SAID ONE COMPOUND IN SAID UPWARDLY MOVED CONTAINER, WHEREUPON THE MOVEMENT OF SAID FIRST AND SECOND COMTAINERS IS REVERSED, WITH THE CYCLE OF UPWARD AND DOWNWARD MOVEMENT OF SAID FIRST AND SECOND CONTAINERS CONTINUING AND TRANSFORMING SAID FIRST STREAM INTO SAID SECOND STREAM OF SOLUTION.

Claim 3
Dependent Claim
129 words
An apparatus as defined in claim 1 wherein said first means includes: c. a container having a liquid inlet and a liquid outlet spaced therefrom, and with said first stream of liquid moving in said container from said inlet to said outlet; d. second means for discharging said liquid to said inlet at a first rate; e. third means for withdrawing said liquid from said container at a second rate that is less than said first rate effected by said second means; and f. fourth means for controlling the rate at which liquid discharges into said container through said inlet to that of said second rate at which said third means discharges liquid through said outlet to maintain said liquid at a predetermined constant surface level in said container.
Claim 4
Dependent Claim
30 words
An apparatus as defined in claim 2 wherein said fourth means is a float-controlled valve operatively associated with said inlet, and the float of said valve disposed within said container.
Claim 5
Dependent Claim
166 words
An apparatus as defined in claim 3 wherein said second means is a power-driven pump, the suction side of which is in communication with a second moving stream of said liquid into which it is desired to discharge said second stream of solution, said pump having a discharge that is in communication with said inlet of said container, with said third means being an eductor that receives a portion of said discharge of said liquid from said pump and returns the same to said second stream of liquid, which eductor includes a tubular portion that is at a negative pressure and in communication with said outlet in said container, with said portion of said liquid discharged to said eductor by said pump being such as to cuase said eductor to withdraw said second stream of solution from said container and discharge the same into said second moving stream of liquid concurrently with said liquid that has passed through said eductor from said pump being discharged thereinto.
Claim 6
Dependent Claim
53 words
An apparatus as defined in claim 1 which further includes: means for longitudinally adjusting said beam relative to said fulcrum means to permit said first and second weights of said first and second compounds to be supported in any desired ratio from said beam, and with said beam being in a horizontal position.
Claim 7
Dependent Claim
66 words
An apparatus as defined in claim 1 which further includes: means for raising and lowering said balance means relative to said first means to permit the magnitude of the surfaces of said first and second weights of said first and second compounds in contact with said first stream of liquid to be varied when said first and second weights are in balance on said balance means.
Claim 8
Dependent Claim
17 words
An apparatus as defined in claim 1 wherein said first and second compounds are in particled form.
Claim 9
Independent Claim
332 words
An apparatus for use in automatically dissolving first and second compounds in a first moving stream of a liquid in which they are soluble to provide a second moving stream of a solution in which said first and second compounds are dissolved in a weight ratio that is proportional to first and second weights of said first and second compounds, said apparatus including: a. first means for defining a first moving stream of said liquid of substantially constant velocity; and b. elongate balance means pivotably supported by a fulcrum means intermediate the ends thereof and having first and second ends that initially support first and second means holding means which hold first and second weights of said first and second compounds, respectively, in said first stream in such relative vertical positions that said first stream contacts equal surfaces of said first and second compounds, with said balance beam means moving the one of said holding means holding the weight of said one compound that dissolves most rapidly upwardly to expose less of said surface thereof to said first stream and lowering the other of said holding means holding the weight of said other compound into said first stream to expose more of said surface thereof to said first stream until the weight of said other compound in said lowered holding means has been so decreased by dissolving in said first stream that is is lighter than the weight of said one compound in said upwardly moved holding means, whereupon the movement of said first and second holding means is reversed, with the cycle of upward and downward movement of said first and second holding means continuing and transforming said first stream into said second stream of solution, said first and second weights of said first and second compounds being in the form of solid cakes thereof, and the holding means being adapted for removable engaging said cakes to support said cakes from the first and second ends of the balance beam means.
Claim 10
Independent Claim
332 words
An apparatus for use in automatically dissolving first and second compounds in a first moving stream of a liquid in which they are soluble to provide a second moving stream of a solution in which said first and second compounds are dissolved in a weight ratio that is proportional to first and second weights of said first and second compounds, said apparatus including: a. first means for defining a first moving stream of said liquid of substantially constant velocity; and b. elongate balance means pivotably supported by a fulcrum means intermediate the ends thereof and having first and second ends that initially support first and second means holding means which hold first and second weights of said first and second compounds, respectively, in said first stream in such relative vertical positions that said first stream contacts equal surfaces of said first and second compounds, with said balance beam means moving the one of said holding means holding the weight of said one compound that dissolves most rapidly upwardly to expose less of said surface thereof to said first stream and lowering the other of said holding means holding the weight of said other compound into said first stream to expose more of said surface thereof to said first stream until the weight of said other compound in said lowered holding means has been so decreased by dissolving in said first stream that is is lighter than the weight of said one compound in said upwardly moved holding means, whereupon the movement of said first and second holding means is reversed, with the cycle of upward and downward movement of said first and second holding means continuing and transforming said first stream into said second stream of solution, said first and second weights of said first and second compounds being in the form of solid cakes thereof, and the holding means being adapted for removable engaging said cakes to support said cakes from the first and second ends of the balance beam means.
