A resin composition preparation apparatus and a polyurea resin are provided. A resin introduction unit is configured to inject a composition solution and air mixed in the composition solution. An air bubble generator is connected to the resin introduction unit. An air bubble separation tank is connected to the air bubble generator. The air bubble generator comprises: an inlet through which the composition solution and the air are introduced from the resin introduction unit; an outlet through which the resin composition is discharged to the air bubble separation tank; and an internal flow channel connecting the inlet and the outlet so as to pass therethrough. The internal flow channel comprises a groove portion configured to form the air bubbles having a smaller particle size than that of the air.

Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 m. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

A dissolved hydrogen liquid-discharging pot makes it easier for a user to use hydrogen water by making the pot capable of discharging or spraying a liquid in which hydrogen is dissolved continuously for a constant period at a prescribed pressure. The internal pressure of a pressure chamber, the volume of which has been subdivided by an indicator line on a pot body, is maintained with hydrogen, which is generated by a hydrogen-generating agent disposed in a hydrogen-generating section, at a discharge pressure that is sufficient to discharge all of the liquid inside a bottle section while an on-off valve that opens and closes a discharge tube is closed, and when the on-off valve is opened intermittently or continuously, at a pressure sufficient for continuing discharge of the liquid inside the bottle section and performing continuous discharge of dissolved hydrogen liquid until the bottom of the bottle section is reached.

The present invention describes methods, systems, and appliances that allow a user to prepare a wide array of different types of customizable beverages using various combinations of base liquids and ingredients. These methods, systems and appliances allow users to design and prepare various types of beverages, both carbonated and non-carbonated, that incorporate various ingredients. These methods, systems, and appliances allow for such beverages to be prepared at varying pressures and temperatures, allowing users to custom-design individual servings of beverages such as beers, wines, ciders, and spirits.

In order to develop devices and methods for impulse ejection of medium, a device for impulse ejection of medium is proposed, comprising a medium chamber for holding a medium, said chamber being defined by an ejection tube and a sleeve, adjoining the ejection tube at the opposite end from the ejection end thereof, and a propellant chamber) for holding a propellant, said propellant chamber surrounding at least partially the medium chamber in the region of the sleeve, wherein the sleeve is designed for movement between a pressure position and an ejection position and seals, in the pressure position, the medium chamber from the propellant chamber at an end plate and wherein the sleeve in the ejection position is spaced apart from the end plate such that there is fluid communication for passage of the propellant from the propellant chamber into the medium chamber.

The present invention describes methods and devices in which concentrated beverage products, each packaged in a pressurized container, can be combined with liquids and/or other ingredients to produce one or more servings of a beverage. These products provide users with a convenient way to prepare both alcoholic and non-alcoholic beverages (including carbonated beverages) in various serving sizes and quantities by combining the pressurized beverage concentrate with (possibly carbonated) liquids and other ingredients.

A hybrid contact tray for a mass transfer column is provided. The contact tray includes a tray deck for passage of liquid along a liquid flow path thereon. The tray deck has a plurality of orifices for passage of ascending vapor through the tray deck, a cross-current vapor-liquid mixing section having a first portion of the plurality of orifices, and a co-current vapor-liquid mixing section including at least one co-current mixing device associated with a second portion of the plurality of orifices. The tray deck also has features capable of altering liquid head levels with respect to the plurality of orifices such that the liquid head level within the co-current vapor-liquid mixing section is greater than the liquid head level within the cross-current vapor-liquid mixing section.

The present invention relates to methods and systems for producing a foamed adhesive. A method for foaming an adhesive includes feeding an adhesive from a supply storage tank to a pump, conveying the adhesive outputted by the pump through an adhesive flow meter, injecting an air into the adhesive once the adhesive travels through the adhesive flow meter, feeding a mixture of the adhesive and air to a static mixer, mixing the mixture homogeneously with the static mixer such that the adhesive is foamed, and transporting the foamed adhesive to a product storage tank.
