Abstract: A method and system for controlling ventilation in a welding helmet is provided. The invention may be adapted to a wide variety of system types, and may reduce or eliminate the need for a shroud or barrier around the head and neck of the welder, of the type used in PAPR systems. The airflow system includes forward and rearward air streams, directed onto the face of the welder, onto the top of the head of the welder, and toward the back of the head of the welder. The air streams help to cool the welder, provide a fresh source of air for breathing, and create a positive pressure system that reduces or excludes entrainment of contaminated external air into the forwardly directed air flow. Certain embodiments may include streams that are filtered, split or redirected via deflectors and conduits to achieve the aforementioned goals.

Abstract: A quick connect/disconnect coaxial hose assembly comprises male and female half hose assemblies wherein the half hose assemblies respectively comprise a male and female connector, an outer tube member for conducting a first fluid therethrough, an inner tube member for conducting a second fluid therethrough, a joint retainer nut member for securing the male and female connectors together, and a sleeve member mechanically and fluidically connecting axially inner ends of the inner tube members together. Threaded disengagement of the joint retainer nut member releases the male and female connectors from each other, whereby the half hose assemblies may be readily pulled apart in opposite axial directions disengaging the axially inner end of one of the inner tube members from the sleeve member so as to achieve quick disconnection of the hose assembly. Subsequent axial engagement of the inner end of the inner tube member with the sleeve member, insertion of the male connector within the female connector, and re-engagement of the joint retainer nut member achieves quick connection of the hose assembly.

Abstract: A material deposition system includes a frame, a support coupled to the frame to support an electronic substrate during a deposit operation, a gantry coupled to the frame, and a deposition head coupled to the gantry. The deposition head is movable over the support by movement of the gantry. The deposition head includes a chamber to hold material, an actuator to push a volume of material out of the chamber, a needle extending from the chamber and terminating in a needle orifice, and at least two air jets located on opposite sides of the needle orifice. A desired volume of material is formed at the needle orifice in response to the actuator, and each of the at least two air jets produce a timed pulse of air to create a micro-droplet from the desired volume and to accelerate the micro-droplet to high velocity.
