    Abstract: Various embodiments comprise apparatuses and methods for capturing particles from a particle-laden airstream. An embodiment of a device includes an inlet air passage to direct a particle-laden airstream, an outlet air passage, an impaction nozzle in fluid communication with and downstream of the inlet air passage, and a channel in fluid communication with and downstream of the impaction nozzle and upstream of the outlet air passage. An open portion of the channel is oriented substantially toward the inlet air passage and has a cavity at least partially covered with a substrate material. A base of the substrate material is substantially normal to an incoming direction of the particle-laden airstream. Other embodiments of the device and a method of using the device are also provided.

    Abstract: The present subject matter relates to a method and system for pulsed air-actuated micro-droplet on demand jetting, especially for jetting high viscosity liquids. A needle (20) extends from a liquid chamber and terminates in a drop-forming orifice outlet (30) from which micro-droplets are generated. At least two air jets (40,50) direct a timed pulse of air at the drop-forming orifice outlet of the needle. The pulsed air is synchronized with the formation of a desired volume of liquid at the orifice outlet to extract and propel a micro-droplet at high velocity to a substrate. The air jets are turned on prior to the forming of the desired volume at the orifice outlet of the needle, and turned off after the micro-droplet had been produced.

    Abstract: A system for dispensing pulverulent coating material comprises a source of pulverulent coating material (6), a source of compressed gas (8), a device (38) for movably supporting a nozzle, the nozzle coupled to the source of pulverulent material and providing an opening (10) through which the pulverulent material is dispensed, a deflector (12) supported by the device and spaced from the opening to aid in shaping a cloud of dispensed coating material, and a source of high-magnitude electrostatic potential (15) coupled to impart electrostatic potential to the dispensed pulverulent material. The deflector includes at least one first passageway (131) extending with a radial component of the deflector and communicating with the source of compressed gas to direct gas with a radial component into the cloud of dispensed coating material.

    Abstract: An airflow system is provided for a welding helmet. The airflow system includes an air intake (16) with a filter, a blower, and a battery mounted to the rear of headgear for a welding helmet. A manifold wraps around the side and front of the headgear and directs air from the- blower to the front of the headgear. The manifold includes a lower vent (26) for directing air onto a user's face and an upper vent (30) for directing air over a user's head toward the rear of the headgear. The vents are intended to create positive pressure to impede the entry of unfiltered air into the user's breathing zone. The manifold further includes a portion of flexible tubing (22) for adjusting the size of the airflow system in conjunction with adjustment of the headgear diameter. The airflow system generally conforms to the structure and shape of the headgear to maintain a location close to the user's head.
