Claims
- 1. A method for mixing a measured amount of nonvolatile material with a measured amount of volatile liquid and for maintaining the proportion of such measured amount of material in such measured amount of liquid at substantially a constant level, the steps comprising, feeding said volatile liquid into an insulated vessel and by volatilizing a portion of said liquid and by circulating a coolant to lower the temperature of said vessel and said liquid therein, while continuing to feed said liquid into said vessel and after said liquid at said lowered temperature has reached a predetermined level in said vessel adding to said liquid in said vessel said measured amount of non-volatile material, continuing said feed of said liquid into said vessel until the liquid level of said volatile liquid in said vessel reaches said measured amount, as said liquid volatilizes, adding to said vessel additional of said liquid and maintaining said volatile liquid in said vessel at said measured amount and, while feeding said liquid and said non-volatile material to said vessel, agitating said liquid and said non-volatile material in said vessel.
- 2. A method, as recited in claim 1, in which said volatile liquid is liquid ammonia.
- 3. A method, as recited in claim 2, in which said non-volatile material is fabric finishing material.
- 4. A method, as recited in claim 3, in which said non-volatile material is a fabric dye.
- 5. A method, as recited in claim 3, in which said non-volatile material is a resin.
- 6. A method, as recited in claim 1, including the further steps of feeding said mixed and agitated liquid and non-volatile material from said vessel to a trough where said mixed liquid and material are to be used and, while said mixed and agitated liquid and material are being so fed, cutting off the further feed of liquid into said vessel.
- 7. A method, as recited in claim 6, in which said measured amount of non-volatile material and said measured amount of volatile liquid are fed, mixed, agitated and maintained at substantially a constant level sequentially in a plurality of insulated vessels, all connected to said trough, said feeding, mixing and agitation being carried on in one of said vessels with the mixed and agitated liquid and material from another of said vessels is being fed to said trough.
- 8. A method, as recited in claim 7, in which said volatile liquid is liquid ammonia.
- 9. A method, as recited in claim 8, in which said non-volatile material is fabric finishing material.
- 10. A method, as recited in claim 9, in which said non-volatile material is a fabric dye.
- 11. A method, as recited in claim 9, in which said non-volatile material is a resin.
- 12. A method for mixing a measured amount of non-volatile material with a measured amount of volatile liquid and for maintaining the proportion of such measured amount of material in such measured amount of liquid at substantially a constant level, the steps comprising, feeding said volatile liquid into a vessel and by volatilizing a portion of said liquid to lower the temperature of said vessel and said liquid therein, while continuing to feed said liquid into said vessel and after said liquid at said lowered temperature has reached a predetermined level in said vessel adding to said liquid in said vessel said measured amount of non-volatile material, continuing said feed of said liquid into said vessel until the liquid level of said volatile liquid in said vessel reaches said measured amount, as said liquid volatilizes, adding to said vessel additional of said liquid and maintaining said volatile liquid in said vessel at said measured amount and, while feeding said liquid and said non-volatile material to said vessel, agitating said liquid and said non-volatile material in said vessel.
