A positive displacement mixer and method for mixing a product that mixes at least two materials into a homogenous product. The positive displacement mixer has at least one positive displacement element having a length, a primary compartment, and a moving element, and two or more minor positive displacement elements each having a length, a minor compartment, and a moving element. The primary compartment and the minor compartments are fluidly connected and during mixing the primary compartment and minor compartments are closed to the atmosphere.

A mixer for mixing multi-component materials includes a mixing element and an inlet. The mixing element is arranged at a longitudinal axis of the mixer for mixing multi-component materials. The inlet section is arranged at the longitudinal axis.

An adapter couples to a container and includes an adapter body and a mixing element. The adapter body includes a neck section and a cap section. The neck section has a first interior surface that defines a first channel extending therethrough. The cap section is coupled to the neck section. The cap section has a second interior surface that defines a second channel extending therethrough that is in fluid communication with the first channel. The mixing element is coupled to the first interior surface and extends into the first channel.

A nozzle for dispensing a beverage includes a nozzle head having a base liquid inlet configured to receive a base liquid and a flavoring inlet configured to receive a flavoring. The nozzle further includes a diffuser assembly that is in fluid communication with the base liquid inlet and which includes a diffuser plate having a plurality of peripheral openings through which the base liquid flows. The nozzle further includes a receptacle that is in fluid communication with the diffuser assembly and the flavoring inlet. The receptacle of the nozzle includes an inner wall, and the peripheral openings of the diffuser assembly are arranged so as to direct flow of the base liquid along the inner wall of the receptacle. The receptacle further includes an outlet through which the flavoring and the base liquid are dispensed.

A mixing and dispensing device and method. In particular, the device used by the applied method reduces the risk of chlorine gas formation while providing a stable, effective and safe disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device includes a highly concentrated disinfectant and dilutes the concentrate through the device while simultaneously mixing the concentrate with a dilute solution of an organic acid. The two diluted solutions are mixed without production of chlorine gas and to a level of safety before being dispensed to produce the stable, effective and safe neutral pH sodium hypochlorite solution disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device can be in the form of a kit for retrofitting into institutions or isolated, remote areas in need thereof or for off the shelf use in the home.

A treatment apparatus for a mixing device having a concentric barrel configuration. The treatment apparatus includes a manifold including an input end and an output end. The treatment apparatus also includes a conduit body having a manifold end and a nozzle end. The manifold end is connected to the output end of the manifold, and the conduit body includes at least one nozzle at the nozzle end of the conduit body opposite the manifold. At least one fluid pathway is formed between the input end of the manifold, the conduit body, and the at least one nozzle.

Provided is a liquid supply apparatus which is capable of directly taking in a liquid from a flow channel and appropriately mixing a gas into the liquid when generating-nanobubbles in the liquid using an ultrafine bubble generating apparatus. The liquid supply apparatus comprises a flow channel for a liquid supplied from a liquid supply source and an ultrafine bubble generating apparatus for generating nanobubbles in the liquid. The ultrafine bubble generating apparatus is provided with: a liquid ejector for ejecting the liquid taken in from the flow channel; a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector; and a nanobubble-generating nozzle for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. The pressure of the liquid in the flow channel flowing into the liquid ejector from the upstream-side of the liquid ejector is a positive pressure and, between the liquid ejector and the-nanobubble-generating nozzle, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the nanobubble-generating nozzle.

A fiber bundle contactor may include a vessel including a first inlet; a second inlet; a mixing zone arranged in the vessel to receive a first fluid from the first inlet and a including fluid from the second inlet, wherein the mixing zone comprises a perforated plate assembly comprising a plate, a plurality of openings in the plate, and a plurality of riser pipes that extend from the plate and arranged to allow fluid flow through additional openings in the plate; and an extraction zone including a fiber bundle arranged in the vessel to receive the first fluid and the second fluid from the mixing zone.

A mixer for mixing multi-component materials includes a mixing element and an inlet. The mixing element is arranged at a longitudinal axis of the mixer for mixing multi-component materials. The inlet section is arranged at the longitudinal axis.

A gas delivery system and method for delivering reactants such as a first gas through a first conduit and a second gas through at least one second conduit, for example, through a plurality of second conduits. The plurality of second conduits may each have a length, wherein at least a portion of the length is entirely disposed within the first conduit. In an implementation, the first conduit may deliver carbon monoxide and the one or more second conduits may deliver carbon monoxide doped with a catalyst such as iron pentacarbonyl. The first and second gases may be introduced into a reaction vessel such as a reactor chamber and used to form carbon nanotubes.
