An alloy wheel is formed having a three dimensional configuration defining a face and recessed surfaces. The face of the wheel is machined providing a smooth surface at the face and defining an edge between the smooth surface of the face and the recessed surfaces. A nozzle element for projecting a plasma jet toward the wheel is provided. The plasma jet is projected toward the smooth surface of the face, the edge, and toward at least a portion of the recessed surfaces forming an alloy oxide at least on the face and the edge disposed between the face and the recessed surfaces. A first polymeric coating is applied over the face, the recessed surfaces and the edge disposed between the face and the recessed surfaces.

A nozzle assembly for spraying cooling fluid in a steam-desuperheating device, includes: a nozzle body; a plug element movably attached to the nozzle body; and a splitter member fixed to a front face of the plug element. The splitter member has at least one splitter arm extending across the flow passage formed in the nozzle body as viewed from the front of the plug element to deflect flow of fluid sprayed through the flow passage.

Systems and methods for humidifying ventilator delivered breathing gases are disclosed. These systems and methods utilize a hollow cone atomizer (e.g., a pressure swirl atomizer) and/or a heating element associated with a heating circuit and/or a heating tube. In some aspect, the systems and methods utilize received flow, temperature, and/or humidity information to determine an amount of water to add to breathing gases to reach a desired humidity of the breathing gases delivered to the patient. In further aspects, the humidification system can serve as a nebulization system for delivering nebulized medicine.

An atomizing cutting fluid system. The system includes a common chamber terminating in a shaped droplet nozzle and including a nozzle section immediately behind the shaped droplet nozzle. An atomizer creates spray directly within the common chamber behind the nozzle section. A cutting fluid supply line provides cutting fluid to the atomizer. A high velocity gas nozzle within the nozzle section and behind the droplet nozzle is configured to provide a high velocity gas to entrain the flow of droplets. The nozzle section and droplet nozzle are configured to produce a fully developed droplets-gas flow at a predetermined distance from the droplet nozzle. In a cutting system, the spray system provides a uniform film for a macro or micro cutting operation at sufficient flow rates.

Provided is a refreshing device including a fan mounted onto a base. The base includes a main container for storing a fluid, a mini fan, and a nebulizer to set in motion the fluid nebulized outside of the main container toward a diffuser positioned downstream from the fan. The diffuser includes an outlet opening having a substantially annular shape, the outlet surface of the outlet opening being substantially perpendicular to the direction of airflow generated by the fan.

A water spraying fan for firefighting. The water spraying fan includes a fan mechanism mounted onto a rotatable surface attached to a base. The fan mechanism has a plurality of fan blades connected to a power source and adapted to rotate quickly, creating a strong air flow when powered on. A cage encloses the fan blades and includes one or more circular manifolds secured to a front side and positioned concentric to the fan blade axis. The manifolds contain a plurality of nozzles that are configured to disperse a liquid, such as water. The manifolds are connected to a water source via a flow control box. When activated, water flows out of the nozzles and is carried across an extended distance via the water pressure and the strong air flow created by the fan mechanism. The water spraying fan can be rotated or tilted to achieve optimal positioning.

Aerosols can be created by filament stretching and breaking of Newtonian and non-Newtonian fluids by applying a strain to and stretching the fluid. The fluid is stretched along a strain pathway and forms a fluid filament between diverging surfaces. The stretched fluid filament breaks into droplets that can be harvested to form a mist or aerosol. The aerosol creation systems can include one or more pairs of counter-rotating rollers that are positioned adjacent to each other that stretch the fluid or a pair of pistons that move toward and away from each other to stretch the fluid. Some aerosol creation systems can include multiple pairs of counter-rotating rollers that are positioned in a circular, oval, or linear pattern. The aerosol creation system with multiple pairs of counter-rotating rollers can generate mist is one or more directions and can be positioned between two concentric rings or linearly, among other configurations.

The invention relates to a wall-flow filter, to a method for the production and the use of the filter for reducing harmful exhaust gases of an internal combustion engine. The wall-flow filter was produced by exposing the filter at least twice successively to a powder-gas aerosol.

The invention includes an air mover device used for fire mitigation and protection. The core component is an air mover unit whose discharge airstream can be positioned using air rudders and/or a directional control assembly to provide air flows in optimum directions and capacity to counter unwanted fire progression or to promote fires in cases of back-burns. Additional support components include a power supply, its fuel source, a speed control mechanism for the air mover, an air mover inlet protective screen, a sparger unit to impart suppressant or retardant into the airstream, balancing feet, a removable nozzle, and instrumentation and controls to ensure function and safety of equipment and personnel. This device can be on a static or mobile platform, towed or self-propelled and can be locally or remotely controlled.

The present invention is a bubble, fog, haze, and fog-filled bubble machine. In particular, the present invention is directed to a single unit machine that can produce bubbles, fog, fog-filled bubbles or haze. The machine preferably comprises a housing having a front portal, a bubble section, a fog section, and a control interface, where the housing is connected to a power source. The bubble section is located behind the front portal and has a bubble wand motor attached to a rotatable wheel with a number of bubble wands. The bubble wands pass through a bubble fluid reservoir. The fog section is located behind the bubble section and comprises a fog outlet in front of a fan, where the fog outlet is connected to a fog heater core and a fog pump is in turn connected to a fog fluid reservoir. The control interface controls the selection of effects.
