A fuel atomizer that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

A particle diameter is decreased and a surface area per unit flow amount is increased by spraying a VOC-containing liquid from a spraying device spraying that is a two-fluid nozzle in a vacuum container, so that only water in the VOC-containing liquid can be greatly evaporated and exhausted, and a concentrated VOC-containing liquid having high concentration can be refined and processed.

A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.

Embodiments of the present disclosure describe a mixing nozzle, system implementing the mixing nozzle, and corresponding method of use. The mixing nozzle includes a housing defining a mixing chamber that has a sidewall separating a first end from a second end. A set of tangential feed conduits, which are oriented tangentially to the mixing chamber, extend outwardly from the mixing chamber, through the housing. An outlet orifice is located in the second end, which is one end of an exit channel extending through the housing.

Disclosed is a compact spraying module for spraying a liquid in the form of droplets for treating a target. The module includes a spraying unit including a nozzle containing at least one spraying member and a fan that is capable of generating a carrying air flow in the nozzle and of carrying the droplets originating from the member to the target. The module includes its own liquid supply system that and includes an electric pump, an electronic control and monitoring unit, a holder that keeps the pump near the spraying unit, an individual communication interface, and a power supply interface. Also disclosed is a system for spraying and controlling a plurality of such modules and to a method for controlling modules of such a system.

Disclosed is a spraying unit intended for spraying a liquid onto vegetation and including: a nozzle formed by a tube, a rotatable atomizer, and a fan generating a carrying air flow around the atomizer, a drive system, and a transport unit for transporting the liquid to the atomizer, which is capable of breaking the liquid up into droplets. The nozzle encloses a body surrounded by the carrying air flow and including a rotatable portion formed by the rotatable atomizer, the rotation of which causes droplets in the carrying air flow to be propelled, preferably in a direction substantially perpendicular to the longitudinal axis. Also disclosed is a compact spraying module including such a unit and to a spraying and control system including a plurality of such modules.

A dispense tip constructed and arranged to communicate with a material dispensing pump comprises an elongated neck and a molded base having a first portion and a second portion opposite the first portion. The neck extends from the first portion of the base. The second portion is constructed and arranged to abut an outlet surface of the pump. An outermost region of the second portion of the base includes a compressible fluid-tight surface that compliantly conforms to the outlet surface when the dispense tip is mounted to the pump.

Apparati for generating a mist are disclosed. One apparatus is disclosed, which has an elongate hollow body (12) and an elongate member (14) located within the body (12). A transport fluid passage (16) and a nozzle (32) are defined between the body (12) and the elongate member (14). The transport fluid passage (16) has a throat portion of reduced cross-sectional area and is in fluid communication with the nozzle (32). The elongate member (14) includes a working fluid passage (26) and one or more communicating openings, such as for example, bores, annuli, and combinations thereof, (30) extending radially outward from the working fluid passage (26). The openings (30) permit a working fluid (e.g. water) to be passed into the transport fluid passage (16), whereupon the working fluid is subjected to shear forces by a high velocity transport fluid (e.g. steam). The shearing of the working fluid results in the generation of a mist formed from droplets of substantially uniform size. Methods of generating a mist using such apparati are also disclosed. Also provided are mists for fire suppression produced using an apparatus disclosed herein, as well as fire suppression systems that include any of the apparati disclosed herein. Further provided are devices, methods, and mists for various other applications including turbine cooling and decontamination.

A prosthetic heart valve includes a base and a plurality of polymeric leaflets. Each leaflet has a root portion coupled to the base, and each leaflet has an edge portion substantially opposite the root portion and movable relative to the root portion to coapt with a respective edge portion of at least one of the other leaflets of the plurality of leaflets. Each leaflet includes) at least two polymers along at least one portion of the leaflet, and each leaflet has a composition gradient of each of the at least two polymers along at least one portion of the leaflet.
