The water carbonation method and apparatus of the present invention consists of a square mixer within a carbonated chamber. The mixer is partially filled with water. Carbon dioxide is then added above the level of water. A rotating member attached to the mixing motor then mixes the water and carbon dioxide to from a carbonated solution. Varying the time for which the carbonation operation is carried on may vary the degree of carbonation. After the specified carbonation cycle, excess carbon dioxide is then relieved through an exhaust solenoid and the remaining carbonated solution is released through the dispensing solenoid into a cup.

The invention provides a method for producing bubbles that exhibit an excellent monodispersity. The invention relates to a method for generating bubbles by the injection and dispersion of a gas through a porous body into a liquid, wherein the value produced by dividing the pore diameter that accounts for 10% of the total pore volume in the relative cumulative pore distribution curve of the porous body by the pore diameter that accounts for 90% of the total pore volume in the relative cumulative pore dismeter distribution curve of the porous body is 1 to 1.5.

An ultrasonic mixing system having a treatment chamber in which antimicrobial agents, particularly, hydrophobic antimicrobial agents, can be mixed with one or more formulations is disclosed. Specifically, the treatment chamber has an elongate housing through which a formulation and antimicrobial agents flow longitudinally from a first inlet port and a second inlet port to an outlet port thereof.

Hydrogen molecule (H₂) has been indicated as a novel anti-oxidant reagent specifically targeting OH free radicals. This invention discloses the methods and apparatus that can be used to increase the hydrogen concentration in water, in beverages, and in other hydrogen absorbing materials through a sealed hydrogen gas producing chamber made of materials that have good hydrogen permeability and can withhold gas pressure. The disclosed method and apparatus can increase the hydrogen concentration quickly without leaking other chemical by-products of the gas producing system into the treated materials.

A method and apparatus for providing an evenly mixed additive enhanced gypsum slurry to a web. Calcined gypsum and water are inserted into a mixer through at least one inlet of the mixer. The contents are agitated to form a slurry. The slurry is passed from an outlet of the mixer into a conduit. An additive is introduced into the slurry along a length of the conduit to achieve a flow stream of a slurry/additive mixture. A cross section of the flow stream is expanded in the conduit while not changing direction of the flow stream and a direction of the flow stream is changed while not expanding the cross section of the flow stream and conduit, all prior to the flow steam exiting from an outlet of the conduit.

An apparatus for delivering water vapor to a gas is formed from a plurality of hollow fiber membranes each defining a passage for the flow of gas from an upstream end of the passage and enclosed by an enclosure. The hollow fiber membranes have a combined surface area in the range of about 90 square centimeters to about 110 square centimeters. The enclosure contains an air inlet positioned to direct air to the upstream end of each of the passages of the hollow fiber membranes and an air outlet positioned to direct air from the downstream end of each of the passages of the hollow fiber membranes. The enclosure preferably has a water inlet positioned to direct water toward the outer surfaces of the hollow fiber membranes and a water outlet positioned to direct water from the enclosure.

Methods and apparatus for introducing a gas into the reaction zone of a reactor. Such methods and apparatus can more evenly distribute the gas throughout the reaction zone.

The invention discloses a nano micro bubble generation device for bathing and a bathing system. The nano micro bubble generation device comprises a gas generator, a water supply device and a mixer, wherein the mixer at least comprises a static mixing element and a mixing pipeline; at least one mixing cavity is formed in the static mixing element and the mixing cavity is filled with particle fillings and/or porous structural matters. The bathing system comprises a bathing device and the nano micro bubble generation device. According to the nano micro bubble generation device and the bathing system, dissolvable gas is mixed with and dissolved in the water in the bubble generation device; the water with the dissolved gas under pressure is output to the bathing device; the water with the dissolved gas under pressure becomes normal pressure after being output to the bathing device and released; as the pressure reduces, the dissolved gas in the water forms nano gas micro bubbles which are slowly released; a to-be-washed surface is hit during the burst of the micro bubbles; and dirt is removed and blood circulation is improved.
