20090055987 | Airflow Headgear for a Welding Helmet - An airflow system is provided for a welding helmet. The airflow system includes an air intake 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 for directing air onto a user's face and an upper vent 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 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. | 03-05-2009 |
20090210989 | WELDING HELMET POSITIVE AIR PRESSURING SYSTEM AND METHOD - 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. | 08-27-2009 |
20100224122 | LOW PRESSURE REGULATION FOR WEB MOISTENING SYSTEMS - A system, in certain embodiments, includes a sheet roller configured to feed a sheet along a path, a liquid supply, and a pneumatic supply. The system also includes multiple nozzles coupled to the liquid supply and the pneumatic supply, where each nozzle is configured to pneumatically atomize liquid in a spray zone along the path of the sheet. Furthermore, the system includes a flow controller configured to continuously regulate liquid flow from the liquid supply to the nozzles. | 09-09-2010 |
20100224123 | MODULAR NOZZLE UNIT FOR WEB MOISTENING - A system, in certain embodiments, includes a sheet roller configured to feed a sheet along a path, a water supply, and an air supply. The system also includes a modular nozzle unit selectively combinable with one or more additional modular nozzle units side by side in a row facing the path. The modular nozzle unit includes a water inlet coupled to the water supply, an air inlet coupled to the air supply, and a plurality of nozzles coupled to the water inlet and the air inlet. | 09-09-2010 |
20100224665 | THERMALLY ISOLATED LIQUID SUPPLY FOR WEB MOISTENING - A system, in certain embodiments, includes a manifold including an air tube disposed about a water tube. The system also includes multiple nozzles coupled to the manifold, where each nozzle is coupled to the air tube and the water tube. | 09-09-2010 |
20100224702 | PNEUMATIC ATOMIZATION NOZZLE FOR WEB MOISTENING - A system, in certain embodiments, includes a nozzle. The nozzle includes a liquid passage, a first pneumatic passage, and an exit surface. The exit surface includes at least one recirculation inducing feature configured to reduce deposits adjacent to the first pneumatic passage. | 09-09-2010 |
20100224703 | Pneumatic Atomization Nozzle for Web Moistening - A system, in certain embodiments, includes a pneumatic web moistening nozzle. The pneumatic web moistening nozzle includes a liquid orifice, and a first pneumatic orifice and a second pneumatic orifice disposed on opposite sides of the liquid orifice. The first and second pneumatic orifices are sized longer than the liquid orifice to overlap the liquid orifice. | 09-09-2010 |
20110114076 | COMMERCIAL KITCHEN EXHAUST SYSTEM - An exhaust system includes a hood structure having one or more of (i) an exhaust flow infeed surface extending downward from a lower end of the filter unit that helps to feed the thermal plume toward the filter unit, (ii) a bypass flow transition surface extending upward from the upper end of the filter unit and then forward to aid bypass flow in circulating back toward the filter aperture and (iii) a front wall structure that includes a downwardly extending wall portion with a chamfered and/or curved transition portion at its lower end and a rearwardly extending wall portion. | 05-19-2011 |

20140354733 | Pulsed Air-Actuated Micro-Droplet On Demand Ink Jet - 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 extends from a liquid chamber and terminates in a drop-forming orifice outlet from which micro-droplets are generated. At least two air jets 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. | 12-04-2014 |
