A method of spray applying an agricultural pesticide composition through an induction flat spray tip nozzle, wherein the agricultural pesticide composition comprises: a liquid medium; at least one pesticide dissolved or dispersed in the liquid medium; and a guar or a guar derivative, wherein at least a portion of the guar or guar derivative, typically a cationic guar, is in the form of particles and at least a portion of the particles are dispersed in the liquid medium, wherein the induction flat spray tip nozzle comprises: a spray tip nozzle body comprising: a first end capable of being connected to a liquid supply, a venturi compartment; and a discharge orifice.

The liquid feed nozzle assemblies for a circulating fluid bed reactor comprise (i) a throttle body premixer to combine liquid feed with atomization steam to form a liquid feed/steam mixture comprising gas bubbles in liquid; (ii) a conduit connected to the premixer and to a discharge nozzle to convey a flow of the liquid/steam mixture created by the premixer to the nozzle body; (iii) a discharge nozzle connected to the flow conduit to shear the liquid feed/steam mixture to create liquid feed droplets of reduced size and (iv) a disperser at the outlet of the discharge nozzle to provide a spray jet of liquid feed having an increased surface area relative to a cylindrical jet. The nozzle assembles are particularly useful in fluid coking units using heavy oil feeds such a tar sands bitumen.

Disclosed is a system to generate bubbles. The bubbles may be formed to include a substantially or medically pure gas. The bubbles may be formed on demand and in a selected small size.

An aspirating spray nozzle including a cylindrical nozzle body, an integrated annular shroud and a nozzle cap. The cylindrical nozzle body has an externally threaded first end portion defining an inlet, a second end portion defining an outlet, and a middle portion. The integrated annular shroud encircles part of the nozzle body and has a base which is integrally joined to the middle portion by way of webbing means. The nozzle cap is adapted to be connected to the second end portion of the nozzle body.

In accordance with an example embodiment, there is disclosed herein a sprayer operable to dispense fluid from a fluid reservoir, such as a paint reservoir. The sprayer comprises a rechargeable battery pack that can be employed to provide power to a pump. The pump provides air to a nozzle assembly that is mixed with fluid from the fluid reservoir and dispensed via the nozzle assembly. In particular embodiments, the nozzle assembly comprises a disposable tip insert.

A foam discharger includes a foamer mechanism (20), the foamer mechanism (20) includes: a liquid flow path (50) through which liquid supplied from a liquid supply unit to a mixing part (21) passes; and a gas flow path (70) through which a gas supplied from a gas supply unit to the mixing part (21) passes, the liquid flow path (50) includes an adjacent liquid flow path (51) having a liquid inlet (52) open to the mixing part (21), the gas flow path (70) includes a plurality of adjacent gas flow paths (71) each having a gas inlet (72) open to the mixing part (21), and the liquid inlet (52) is arranged at a position corresponding to a merging part (22) of gases supplied from the plurality of adjacent gas flow paths (71) to the mixing part (21) via the gas inlet (72).

A foam generating device for a high-pressure water gun has a supporting body defining part of a conduit, which extends along an axis and has a mixing chamber communicating with a lower inlet, and subject, in use, to a vacuum to aspirate a liquid from said lower inlet; the device has a first sleeve which is fitted around one end of the supporting body, is axially fixed, is rotatable and is provided with an end portion carrying a nozzle; such a nozzle defines the outlet of the conduit and is adjustable so as to vary the outgoing flow type between a fan-like jet and a solid stream jet; the device has, in addition, a second sleeve which is coupled to the first sleeve in a fixed axial position and in a rotatable manner and is provided with cams to adjust the nozzle in response to a rotation of the second sleeve with respect to the first sleeve.

An apparatus for creating solid or liquid nanoparticles having a nozzle to create a first particle size from a bulk liquid flow that is in fluid communication with a gas flow amplifier comprising an inlet cone connected to and in fluid communication with the inlet of a cylindrical housing; a diffuser connected to and in fluid communication with the outlet of said housing; and said housing comprising at least two rings of ports disposed of along a circumference of the cylindrical housing; and a means to inject compressed gas into the housing through said ports.

A vibrating mesh nebuliser. The nebuliser (100, 400, 500) comprises a cartridge section (110, 420, 520) comprising a reservoir (180) containing a liquid to be nebulised (190), a mouthpiece comprising a conduit (160), wherein a flow path (210) is defined between the reservoir (180) and the conduit (160) and whereby a user may inhale nebulised liquid from the mouthpiece through the conduit (160). The nebuliser further comprises a body section (120, 410, 510), releasably connectable to the cartridge section (110, 420, 520) and a mesh section (530) comprising a vibratable mesh (250, 540), the vibratable mesh (250, 540) being disposable in the flow path (210), so as to nebulise liquid drawn from the reservoir to the conduit in the mouthpiece. Also provided are an apparatus and method for monitoring one or more physiological responses to material self-administered by a user.

A spray device includes a converging assembly, a container and a suction pipe. The converging assembly includes a first liquid channel, a second liquid channel, a first air channel and a second air channel. The first liquid channel and the first air channel communicate with an inlet of the second liquid channel. The second air channel communicates with the container. An end of the suction pipe communicates with the inlet of the second liquid channel, and another end is submerged in a solution in the container. When a liquid flows from the first liquid channel to the second liquid channel, air in the first liquid channel is discharged via the first air channel, the solution is sucked to the second liquid channel through the suction pipe, the solution and the liquid are mixed at the inlet of the second liquid channel, and then are sprayed from the second liquid channel.
