  • Patent number: 4186215
    Abstract: An arrangement for carbonating a beverage over an extended period of time through the addition of water or beverage liquid base to a powdered or dry carbonate and acid located in a pressure chamber. A permeable surface of the chamber allows a small quantity of water to enter and initiate a chemical reaction generating gaseous carbon dioxide. The carbon dioxide will exit the chamber and carbonate the beverage. A resultant pressure drop in the chamber will permit the entry of more water to generate more carbon dioxide until the pressure is balanced, with the sequence being repetitive. A flavoring chamber containing flavor powder may be superimposed on the pressure chamber to effect admixing of the flavoring and liquid concurrent with carbonation. The pressure chamber, and flavoring chamber, may be formed integrally with a container, or may consist of a separate unit adapted to be placed in a container to which water or liquid base is then added.

  • Patent number: 4105725
    Abstract: A process for generating in a pressure vessel a ready supply of a vapor of a normally liquid active substance in an inert carrier gas under pressure and dispensing vapor intermittently from the supply. Once a body of the active liquid substance and overlying atmosphere of vapor is established in the vessel, the vapor is dispensed intermittently in a series of predetermined doses. Simultaneously with the dispensing of each dose, carrier gas is bubbled under pressure into a bottom zone of the vessel in minute bubbles so as to provide saturated vapor, replacing the dose dispensed. A number of conditions are coordinated to insure that saturated vapor is always dispensed. These conditions include the relationship between the depth of the vapor space, the head of liquid above the bubbling zone, the relative amount of each dose, and the initial size of the bubbles. The process is specially useful for gassing cold box cores.
