Abstract:
A controller is provided for an inkjet airbrush system which uses inkjet printing technology for color mixing in airbrush painting, and for other fluid application systems. The controller is used to select a desired fluid blend or custom color which is blown by the inkjet airbrush onto an object. Firing signals, generated in response to the controller input, cause a printhead to eject a custom blend of colors which are combined in a mixing chamber and then atomized. The controller may be a remote device, or provided on-board the inkjet airbrush unit, preferably, as a joystick toggling device. The amount of colorant passing through the airbrush may be varied by varying the firing signal frequency in response to joystick motion or a separate adjustment mechanism. The inkjet airbrush system provides fast color changes and faster clean-up than conventional airbrushes. A method of controlling an inkjet airbrush is also provided.
Abstract:
An inkjet airbrush system uses inkjet printing technology in a new manner for color mixing in airbrush painting. A variety of different configurations are used to generate atomized custom colors which are blown by the inkjet airbrush onto an object. In response to firing signals, a printhead ejects a custom blend of colors which are combined in a mixing chamber and then atomized using any type of atomizer desired. The firing signals may be generated by a remote device, such as a computer, or they may be generated on-board the inkjet airbrush in response to a user input, such as a code selected from a color chart. The amount of colorant passing through the airbrush may be varied by varying the firing signal frequency. The inkjet airbrush provides fast color changes and faster clean-up than conventional systems. A method of applying a fluid on an object is also provided.

Abstract:
A personal or spot area environmental management system has a low pressure air supply in fluid communication with an air nozzle and a water supply in fluid communication with a water nozzle. The air nozzle and water nozzle are arranged that the water nozzle includes a vortex in the air stream from the air nozzle reducing the pressure. The low pressure facilitates drawing water from the water supply through the water nozzle. The water exiting the water nozzle has an average diameter of 60 microns or less, which facilitates complete evaporation and effectively produces a cool, dry air stream.
Abstract:
A process for depositing nanoparticles on a surface. The process includes the steps of: providing a sol including a volatile non-aqueous liquid and nanoparticles suspended in the non-aqueous liquid; processing the sol to form a plurality of droplets; depositing the plurality of droplets on a surface; and evaporating the non-aqueous liquid from the surface leaving a residue of nanoparticles. The liquid can be selected from heptane, chloroform toluene, and hexane and mixtures thereof and the nanoparticles are desirably silver nanoparticles. The plurality of droplets may be formed by a spray process. The surface may be selected from a particular area, region, portion, or dimension of a medical device, device material, packaging material or combinations thereof. The residue of nanoparticles desirably provides antimicrobial properties.

Abstract:
A coating apparatus for coating a rollable device including a device rotator having a pair of rollers and spray nozzle is described. The spray nozzle produces a spray of coating material that is directed towards a gap that is between the rollers of the pair. The majority of any spray not deposited on the rollable device during a coating process passes through the gap between the rollers.
Abstract:
An ultra-fine spray-jetting nozzle includes a liquid passage (37) and a gas passage (41) that is disposed on a peripheral side of the liquid passage (37) through a partitioning wall and communicates with a jetting port (A). An outer surface of the partitioning wall at a jetting port side thereof is formed sectionally polygonal, long circular or elliptic. A peripheral surface of the gas passage (41) is formed sectionally circular. The outer surface of the partitioning wall having the configuration is brought into contact with the sectionally circular peripheral surface of the gas passage (41) at a plurality of positions to circumferentially divide the gas passage (41) at the jetting side into a plurality of gas passages. A gas jetted from jetting ports (A) of a plurality of the separate gas passages is mixed with a periphery of a liquid jetted from the liquid passage (37) to generate spray.
