A method and apparatus for generating droplets with a high level of uniformity in liquid systems that present a low interfacial tension. This method and apparatus utilize the breakup of the dispersed phase in a controlled fashion by periodically varying the pressure that drives the fluids so as to successfully generate emulsions with a good control over the size. The method and apparatus can be used for the formation of simple emulsion or double emulsion where a larger droplet contains one or more smaller droplets.

Foam dispensing systems and methods are disclosed. Such systems and methods may include a foamed material dispenser, a dynamic mixer having a gas input, a process material input, and a foamed material output. The foamed material output may be in fluid communication with the foamed material dispenser. A pump having an output may be in fluid communication with the process material input of the dynamic mixer, and a gas injection valve may be in fluid communication with the gas input of the dynamic mixer. A gas pressure regulator may be coupled between the pressurized gas supply and the gas injection valve, and a gas injection cycle timer may be operatively connected to the gas injection valve, the gas injection cycle timer causing the gas injection valve to pulse open and closed to send pulses of pressurized gas into the dynamic mixer through the gas input.

A bubble generator includes an ejector including a flow passage, a water supplier that supplies water into the flow passage, an air supplier that supplies air into the flow passage, a cleaner supplier that supplies a cleaner into the flow passage, and a bubble discharger that discharges bubbles generated by mixing the water, the air, and the cleaner; a water supply device that supplies water to the flow passage via the water supplier, and a cleaner supply device that supplies the cleaner to the flow passage via the cleaner supplier. The cleaner supplier is formed on a lower surface of the flow passage.

A device for producing a wet granulated substance for an electrode, the device including a storage tank in which a solid component is stored, liquid supply units configured to supply a liquid component, and a stirring member configured to stir the solid component and the liquid component together. The liquid supply unit includes a nozzle configured to allow the liquid component to drop, a pump configured to repeatedly switch between a first state in which a pressure is applied to the liquid component and a second state in which a lower pressure than in the first state is applied to the liquid component, and a rotating member that is provided between the nozzle and the storage tank, has a disk shape with irregularities formed on the edge, and rotates in a non-horizontal plane.

A method for mixing at least two liquid components of a two- or multi-component wet coating system, wherein a feed component under a first hydraulic pressure set at constant is fed discontinuously through a variable passage cross-section to a parent component under a second hydraulic pressure set at constant. An actual feed quantity of the feed component is detected and the feed quantity of the feed component is regulated with respect to a target feed quantity for the feed component in such a way that a timing cycle of the discontinuous feed and the passage cross-section for the feed component are influenced.

In a method for mixing two liquid components of a medium with the aid of a static mixer, the two components are supplied to the static mixer, are mixed therein and are subsequently dispensed from the mixer. In this respect, only one respective component is supplied to the mixer, while the other component is not supplied to the mixer.

A bubble generation system includes a gaseous pressure source supplying a gas flow and a wave inducer including a first inlet in fluid communication with the gaseous pressure source to receive the gas flow and a first outlet. The wave inducer transitions the gas flow into a pulsating acoustic wave that exits the wave inducer through the outlet. The bubble generation system also includes a diffuser fluidly coupled to the outlet of the wave inducer. The diffuser is configured to produce bubbles from the gaseous pressure source. The bubble generation system further includes a vent passageway fluidly coupled between the wave inducer and the diffuser. The vent passageway is configured to be in fluid communication with an ambient environment.

An apparatus for dispensing a mixture of a diluent and an additive for sanitation, cosmetic or cleaning applications. The apparatus includes a mixing unit for creating a mixture of the diluent and the additive, a diluent supply supplying the diluent to the mixing unit, an additive supply supplying the additive to the mixing unit, an outlet for dispensing the mixture. The diluent supply includes a pump arranged to increase the pressure of the diluent before the diluent enters the mixing unit.
