  • Patent number: 6158721
    Abstract: A small flow of a water with a high carbon dioxide content (normally a carbon-dioxide-saturated water) is produced using hollow-fiber membranes, and is uniformly mixed with a large flow of untreated water with constant proportions. Since the hollow-fiber membrane module has a reserve capacity for adding carbon dioxide to the water, the resistivity of the mixed water is maintained at a constant level by maintaining constant proportions of the small and large flows, even if the total flow rate fluctuates due to fluctuations in the rate of water used in a subsequent process. Accordingly, no automated control device is particularly necessary in order to maintain the resistivity at a constant level. Therefore, a compact and simple apparatus can be produced which can operate at a low cost.

  • Patent number: 6036054
    Abstract: The present invention is an attachment that can pressurize a beverage container with carbon dioxide or other suitable pressurized gaseous fluid. The attachment has a first threaded opening that can be screwed onto the container and a second opening which can be coupled to either a pressurized gas cartridge or a pressurized gas tank. Extending from the carbonator is a button that is coupled to a valve which controls the flow of gas into the container. The button and valve are coupled to a spring that functions as a regulator which controls the gas pressure within the container. When the button is depressed, the valve is opened and gas flows into the container until the gas pressure overcomes the spring force and closes the valve. Varying the displacement of the button varies the spring force and the gas pressure within the container. The user can thus vary and control the gas pressure of the container by manipulating the button.

    Abstract: An arrangement for carbonating a solution by pressurization of a defined spatial area in a container in which a carbonating mixture is combined with a solution. The container is typically filled with a solution to a demarcation defining a spatial area. Reactants, an acid and a base, evolve CO.sub.2 when reacted in a solution. The quantity of reactants added is designated so as to generate a quantity of CO.sub.2 which will increase the pressure in a defined spatial area and cause a quantity of CO.sub.2 to redissolve. The result of this arrangement is a solution supersaturated with CO.sub.2. The reaction chamber may also be divided into separate compartments with each compartment containing individual servings. Each compartment has an evacuation device allowing the contents of the compartment to be delivered for consumption without effecting the level of carbonation of the solution remaining in the other compartments of the container.

The device is especially useful as an apparatus for rapidly carbonating liquid beverages with chemically generated carbon dioxide produced in a gas generation chamber located inside a pressure vessel attached to a liquid container which serves as a carbonation chamber containing the liquid to be carbonated. The generated carbon dioxide is passed from the gas generation chamber to the carbonation chamber to carbonate the liquid. This device can also be used as a means of injecting pressurized gas into a pressurized spray can for dispensing liquids such as paint, hair spray or other sprayable products.

  • Patent number: 5543087
    Abstract: A multi-function fluid treatment system which can filter liquids or diffuse gases into liquids. To achieve filtration, the system includes a housing with multiple, closely-spaced filter cartridges therein. The cartridges are connected to a drive system which rotates them in unison. Fluids to be filtered enter the housing and surround the rotating cartridges. Cartridge rotation scrubs solids from the cartridges and promotes fluid flow into the cartridges. Filtered fluids collected within the cartridges thereafter exit the system. To achieve gas diffusion, the housing is filled with a selected liquid. During cartridge rotation as discussed above, a gas is introduced into the interior of each cartridge which is constructed of a porous material. The gas diffuses outwardly during cartridge rotation, causing substantial mixing of the gas and fluid, with gas diffusion into the fluid. Cartridge rotation also prevents solids from accumulating thereon to achieve maximum gas delivery.

  • Patent number: 5518666
    Abstract: In an apparatus and method for maintaining a desired (target) carbonation level in a carbonator, a control-signal originates from a reference standard of carbonated water close to the target carbonation level, which is sealed inside a pilot chamber of the regulator. The pilot chamber is exposed to the water temperature in the carbonator and is shaped and sized so as to promote rapid equalization of the temperature of the reference standard with that of the carbonated water. The pressure inside the pilot chamber is equal to the equilibrium vapor pressure, according to the temperature and carbonation level of the reference standard. This pressure is transmitted through a flexible membrane in one of the walls of the pilot chamber to a valve in the gas-supply line of the carbonator. This valve, therefore, balances the CO.sub.2 gas pressure within the carbonator with the equilibrium vapor pressure in the pilot chamber.

  • Patent number: 5443763
    Abstract: Apparatus including a circulating pump inside a carbonator tank which blends CO.sub.2 with still water and which is started and stopped for predetermined time periods in repetitive cycles having an on/off ratio ranging between 1:10 and 1:20. A timing circuit controls the operating and non operating times of the circulating pump so that sufficient carbonation of the water with CO.sub.2 gas is achieved along with the formation of an ice bank on the cooled wall of the storage tank. During intervening periods when the circulating pump is not operating, the carbonated water arranges itself in layers according to its density so that the relatively warmer water sinks while the colder water together with any ice particles or small pieces of ice floating therein join together, becoming fixed to the ice bank in the upper portion of the carbonator.
