A binary nozzle for atomizing a mixture of agent to be sprayed and spray air is connected to at least one supply duct via which the mixture or the agent to be sprayed can be supplied to the binary nozzle, wherein a valve is arranged between this supply duct and a nozzle outlet of the binary nozzle. A corresponding spray head and also a method for atomizing a mixture of agent to be sprayed and spray air uses a binary nozzle. The binary nozzle includes a nozzle body formed in a single piece and including the nozzle outlet, wherein a movable assembly of the valve is fastened to the nozzle body by a fastening element and/or held tight against the nozzle body by a spring device.

An ultrafine bubble (UFB)-containing liquid manufacturing apparatus includes a liquid ejecting unit having a thermal energy generating element, a flow path for leading liquid to the thermal energy generating element, a driving unit configured to drive the thermal energy generating element, and an ejection opening. The UFB-containing liquid manufacturing apparatus also includes a collecting unit configured to collect liquid ejected from the ejection opening. The driving unit drives the thermal energy generating element to cause film boiling in liquid led to the flow path and causes liquid containing ultrafine bubbles generated by the film boiling to be ejected from the ejection opening.

Proposed is an air mixing nozzle tip structure which improves productivity while simplifying the structure by being configured so that air is introduced through an air mixing inlet and discharged together with wash water, improves cleaning power while realizing a massage effect because fine water droplets are formed in the process that wash water and air are combined and discharged, controls the inlet amount of air by forming the air mixing inlet on one side or each of opposite sides of a nozzle tip cover or by adjusting the cross-sectional size of the air mixing inlet, and promotes product stability by providing an air supply passage at the rear of the air mixing inlet so that the air introduced through the air mixing inlet is smoothly discharged to a wash water ejection hole through an air guide.

A common head for use in combination with a cartridge assembly, the cartridge assembly being retained within the material containment unit of a dispensing device and arranged to discharge reactive components from larger and smaller cartridges in response to actuation of the dispensing device. The common head includes inlet openings and a rigid walled tube having a partition positioned therein to define larger and smaller pathways to enable passage of the reactive components from the cartridges into and though the common head in a predetermined volumetric ratio and prevent backflow of the components which can lead to unintended curing prior to dispensing. A flexible liner arranged for positioning within one or both pathways of the rigid walled tube is also provided to prevent such backflow and unintended curing prior to dispensing.

A cleaning apparatus is provided that includes a first nozzle configured to direct a cleaning jet towards a contaminated surface at a pressure sufficient to remove contaminants from the surface. At least one second nozzle is configured to direct a rinsing jet towards the contaminated surface to remove cleaning fluid therefrom, wherein the rinsing jet is directed at a pressure sufficient to isolate the cleaning jet from an ambient environment.

A makeup machine includes a multi-nozzle spray head and a plurality of needle valves. The multi-nozzle spray head has a main body and a plurality of nozzles. Each of the nozzles includes an interior chamber and an ejection hole, and the interior chamber is communicated with the ejection hole. The needle valves are disposed in the main body and axially aligned with the ejection holes. The needle valves are configured to be axially movable away from the corresponding ejection holes to open the ejection holes and to be axially movable towards the corresponding ejection holes to close the ejection holes. Further, the needle valves are capable of synchronously or individually moving with respect to the main body.

A dispenser system for applying multi-component adhesives or like substances to work surfaces in carpeting, roofing and like applications as well as a method of dispensing and applying multi-component adhesives to work surfaces.
