A multiple pre-orifice apparatus for a sprayer nozzle body with an upper end connected to a liquid source, a nozzle tip releasably mounted at a lower end thereof, and a channel between the upper and lower ends of the nozzle body. The apparatus comprises a sleeve assembly comprising a sleeve closed at an upper portion thereof by a top orifice plate defining a top orifice, and closed at a lower portion thereof by a bottom orifice plate defining a bottom orifice such that a sleeve turbulence chamber is formed between the top and bottom orifice plates. The sleeve assembly is secured in the channel such that a nozzle turbulence chamber is formed between the bottom orifice plate and the nozzle tip. The area of the flow opening in the nozzle tip is greater than the area of the top orifice which is greater than the area of the bottom orifice.

There is provided an exhaust gas processing apparatus which improves the removal rate of harmful substances and also achieves a compact size. An exhaust gas processing apparatus (10) absorbing gas by creating contact between gas and liquid includes: an absorbing tower main body (11) in which an internal space is formed; a spray apparatus (12) which sprays liquid in a prescribed region in an up/down direction of the internal space; and a gas supply apparatus (13) which introduces gas into the absorbing tower main body (11), wherein the spray apparatus (12) includes: a trunk pipe (12b) which extends in the up/down direction in the prescribed region of the internal space; branch pipes (12c) which are connected to the trunk pipe (12b) and extend towards the inner wall of the absorbing tower main body (11); and spray nozzles (12d) which spray liquid supplied from the branch pipes (12c), wherein the spray nozzles (12d) are installed such that an angle formed between the center line of the spraying region of the spray nozzle (12d), and the lengthwise direction of the branch pipe (12c) is an acute angle.

A nozzle for a dissolved air flotation system includes a housing, a nozzle connector, and a nozzle body. The housing has an inlet formed at one side and an outlet formed at another side. The nozzle connector couples to the inlet and has an inflow path formed in a longitudinal direction. The nozzle body is disposed in the housing, and includes: a collision portion formed at a first end portion of the nozzle body such that a fluid introduced along the inflow path of the nozzle connector 10 changes its flow direction and collides with an inner wall of a side portion of the housing, a plurality of faces formed at sides of the nozzle body, a plurality of side paths defined between the faces and the inner wall of the housing, and a spurt hole defined at a second end portion of the nozzle body.

A resin dispensing apparatus is provided. The resin dispensing apparatus includes an external body portion including a discharge nozzle configured to discharge a phosphor-containing resin, and an internal body portion including at least one flow passage, the internal body portion being mounted within the external body portion. An axial length of the internal body portion is shorter than an axial length of the external body portion.

An atomizing nozzle structured particularly for nasal therapy. Preferred embodiments include a 2-piece atomizing nozzle structured to couple with luer-locking structure carried by a syringe. Such an atomizing nozzle includes a nasal stopper and a stem. A preferred nasal stopper includes a distal tip sized for insertion into a nostril of a human child, with a proximal shield portion being structured to resist over-insertion of a discharge orifice into the nostril. A nasal stopper desirably provides a centering function to urge the discharge orifice away from a nasal wall. One operable stem is structured to couple with the stopper and desirably carries unitary thread structure at a proximal end. A second operable stem is structured as a unitary part of the nasal stopper and also desirably carries unitary thread structure at a proximal end. Certain embodiments may also include spacer structure configured to reduce a dead volume inside the atomizing nozzle. Other embodiments may also include spacer structure configured to reduce dead volume inside a syringe that is coupled to the atomizing nozzle.

A fluidic oscillator includes an inlet portion configured to be engageable with a source of pressurized fluid. An oscillating portion is coupled to the inlet portion and includes a central chamber, a pair of side passageways in fluid communication with the central chamber, and an outlet disposed about a central axis. The pair of side passageways are positioned on opposite sides of the central axis, with each side passageway having a feedback inlet that receives fluid from the central passageway and a feedback outlet that returns fluid to the central passageway, with the feedback outlet being positioned between the feedback inlet and the inlet portion. The oscillating portion is configured such that, fluid fills the pair of side passageways in an alternating sequence, which results in fluid exiting the outlet at varying angles relative to the central axis.

Compositions are provided that include having at least 95% by weight of a taxane, or a pharmaceutically acceptable salt thereof, where the particles have a mean bulk density between about 0.050 g/cm.sup.3 and about 0.15 g/cm.sup.3, and/or a specific surface area (SSA) of at least 18 m.sup.2/g, 20 m.sup.2/g, 25 m.sup.2/g, 30 m.sup.2/g, 32 m.sup.2/g, 34 m.sup.2/g, or 35 m.sup.2/g. Methods for making and using such compositions are also provided.

An air-assisted airless spray gun includes a valve cartridge configured to control a flow of air or spray fluid through the spray gun. The valve cartridge includes a housing configured to interface with the spray gun body and fully supporting the flow control components of the valve cartridge. The housing is secured within a bore of the spray gun body. The valve member is supported by the housing and actuatable relative to a seat. The valve is formed between the seal end of the valve member and the seat.
