Abstract:
A nozzle assembly with a self-cleaning face is provided, having a nozzle body with a liquid flow path defined therethrough with an inlet and a spray outlet. The nozzle body is mounted in a carrier body, and an annular gas flow channel is located about the nozzle body with a gas discharge outlet defined around the spray outlet. A porous surface is located about the annular gas flow channel at the gas discharge outlet. A radiused surface is formed in the carrier body at the air discharge outlet. A pathway is in communication with the porous surface and adapted to provide a low velocity fluid discharge from the porous surface. A spray device and method are also provided using the nozzle assembly with the self-cleaning face. An adaptor for retrofitting an existing nozzle is also provided.
Abstract:
An isolator system (100) includes: a substantially box-shaped isolator (110) including a work space (A) isolated from its surroundings; a sterilizing unit (140) configured to spray a sterilizing mist from a nozzle (143) mounted within the isolator (110), the sterilizing mist being obtained by converting a sterilizing liquid into mist; and a control unit (160) configured to control an operation of the sterilizing unit (140), wherein the sterilizing unit (140) is configured to spray the sterilizing mist intermittently when spraying.
Abstract:
A mist blower (10) for spraying chemical liquid includes a blast pipe (60) configured to allow air supplied from a fan (50) to flow through and to be discharged from an front end of the blast pipe (60), the chemical liquid being sprayed by mixing the chemical liquid into the air flowing through the blast pipe (60); and a diffusion cover (80) provided in the front end of the blast pipe (60) to radially outwardly diffuse the air containing the chemical liquid which is being discharged from the blast pipe (60). The diffusion cover (80) includes: a flow directing fin (81) configured to direct flow of the air containing the chemical liquid which is being discharged from the blast pipe (60); and a diffusion fin (82) configured to tilt radially outward with a greater angle than of the directing fins (81) and to radially outwardly guide part of the air containing the chemical liquid.
Abstract:
A device comprises a centrifugal separator for cleaning of a gas, especially a gas containing impurities in the form of solid and/or liquid particles, comprises a stationary casing enclosing a separation space, an inlet channel, a rotating member in the separation space for separating at least a main part of the impurities from the gas, a gas outlet channel, and an outlet for discharging a separated phase of the gas. A supply member (50) is provided for supplying a liquid, to form of an aerosol, to the gas to be cleaned and which comprises a supply conduit (51) with an outlet end (52), and an ejector nozzle (56) connectable to a pressurised gas conduit (57) and comprising a nozzle outlet (58). The nozzle outlet at the outlet end permits ejection of the aerosol from the outlet end by means of the pressurised gas supplied to the ejector nozzle and the nozzle outlet.
Abstract:
A spray gun and a method for use thereof comprises a spray gun body; an air cap; a fluid spray nozzle having a fluid tip; at least one air distribution channel for atomizing air; and at least one air distribution channel for fan air, wherein the fluid spray. The fluid spray nozzle and the air cap are configured to direct an atomization air flow at an angle of substantially 10 to 70 degrees relative to the liquid coating composition jet, into the pre-atomized coating composition jet and produce an atomization air pressure to fan air pressure ratio of substantially 8.0 to 1.5.
Abstract:
The invention relates to a spray gun apparatus (10) for spraying a fine film coating of liquid, such as paint, lacquer or bond, onto a surface. The spray gun comprises a main body (12) having a fluid throughbore (22), a gas throughbore (16), and a main trigger lever (80) for allowing a user to spray fluid from the gun. A fluid flow adjustment mechanism (52, 58, 74) facilitates adjustment of the quantity of fluid sprayed from the gun for a given displacement of the main trigger lever (80). An engagement surface (86) is provided on the trigger lever and adapted to engage with a corresponding engagement surface (90) of the fluid flow adjustment mechanism. Pivoting movement of the main trigger lever (80) results in translational movement of at least a portion of the fluid flow adjustment mechanism to thereby selectively spray fluid from the gun upon displacement of the main trigger lever.

Abstract:
A self-contained portable liquid cosmetic delivery system for both color makeup and skin care applications is provided. The system includes a spray nozzle assembly (54) having both a liquid path and air path communicates with the housing containing a peristaltic and diaphragm pumping systems. A removable cartridge assembly (31) that allows for very quick changing of cosmetic, while also including a cartridge housing (55) that not only configured to enable the use of a peristaltic pump (52) and diaphragm pump (11) to selectively dispense liquid cosmetic contained in the cartridge housing, it can be manufactured at a reduced cost thus making the same easily cleanable and essentially disposable.
Abstract:
Systems and methods that provide or restore a coating to a component are provided. The systems and methods utilized an atomizing spray device. A gas and a slurry that comprises fluid and ceramic particles are supplied to the atomizing spray device. The slurry and gas are discharged from the spray device to form two-phase droplets. The fluid within the droplets evaporates to prevent the fluid from becoming part of the coating as the droplets traverse through the air and prior to impacting the surface of the component.
