An intake manifold for an additive manufacturing system includes a body defining a flow channel therein. The body includes an inlet end defining an inlet configured to intake gas and/or particles from a build area of the additive manufacturing system, and an outlet end defining an outlet that is fluidly connected to the inlet through the flow channel. The outlet is configured to be in fluid communication with an uptake manifold of the additive manufacturing system. The intake manifold also includes at least one mount extending from the outlet end of the body that is configured to rotatably mount the body to the uptake manifold.

An apparatus comprising one or more of a surface treatment apparatus having an air treatment member and a refuse container wherein at least one of the surface treatment apparatus and the refuse container is provided with one or more of (a) a dust control member providing a dust control agent comprising one or more of a liquid mist, positive ions and negative ions to an area below a dirt emptying outlet of a dirt collection region of the surface treatment apparatus; and, (b) a treatment applicator providing a treatment agent comprising one or more of a deodorizing agent, a disinfecting agent and a sanitizing agent to an interior volume of the air treatment member and an interior volume of the refuse container.

A welding accessory apparatus can include a welding lens, a manifold, an articulated arm assembly, and a tube. The welding lens can be mounted to the manifold. The manifold can have an intake aperture, an outlet aperture, and an internal cavity. The articulated arm assembly can be interconnected with the manifold and be adjustable whereby a user can position the manifold and the welding lens among different positions and orientations in three dimensions and then retain the manifold and the welding lens in the selected position and orientation. The tube can be interconnected with the manifold and can communicate with the intake aperture and the internal cavity by way of the outlet aperture. At least part of the tube can be moved and held in place with the manifold and the welding lens by the articulated arm assembly.

An apparatus for manufacturing a display device includes: a stage unit; and a suction unit located above the stage unit, wherein the suction unit includes: a main body including an outer box with top and bottom openings and an inner cup disposed in the outer box; a first air blower disposed above the main body and including a first main pipe extending in a first direction and a second air blower including a second main pipe extending in a second direction intersecting the first direction; a lower plate coupled to a lower end of the outer box and including a through hole; and a suction inlet defined by an inner end of the lower plate defining the through hole and a lower end of the inner cup, wherein the suction inlet is opened downward.

The present invention is a fume extraction swivel system for use on a gas shielded welding device. The fume extraction system includes an extraction hose mounting bracket which has an internal flange adapted to mount about a welding torch. The bracket has a collar spaced from the internal flange that defines an interior space. A packer is mounted in the flange and rotates upon a bearing mounted to the torch. A fume extraction port is in operative communication with the interior space. An intake shroud is mounted to the collar. The fume extraction port, interior space and shroud create an air-path through the extraction hose mounting bracket. In this way, the fume extraction system is connected to an air filter through the extraction port and the air filter draws air along said air-path through the interior space and the intake shroud without interfering with the gas shield welding operation. The swivel mount ensures that the extraction hose does not wrap around the torch.

A surgical drape plume evacuator includes a filter enclosure. An operating aperture disposed in the filter enclosure defines an area within the filter enclosure. A pressure source for creating at least one of a negative and positive air pressure in the filter enclosure. A fluid opening in the operating aperture connects the interior of the operating aperture to the interior of the filter enclosure.

The present invention relates to a dry cleaning technology for a cleaning a surface of an object to be cleaned by adiabatically expanding liquid carbon dioxide to generate sublimable dry ice particles and carrying the dry ice particles on high-speed carrier gas to be sprayed onto the surface of the object to be cleaned, wherein an end of a liquid carbon dioxide nozzle further protrudes to the outside relative to an end of a carrier gas nozzle to prevent a growth of dry ice particles in the carrier gas nozzle, a hydrophobic coating is formed on a surface of the liquid carbon dioxide nozzle to prevent a formation of water droplets and to prevent an occurrence of irregular dry ice particles, thereby effectively preventing damage to a surface of an object to be cleaned and being advantageous in an economical aspect by significantly reducing consumption of liquid carbon dioxide.

The invention relates to a crossjet assembly for generating a gas flow that is conducted between a laser source (40, 41) and a welding region (42) in order to remove contaminants moving towards the laser source. The gas flow crosses the region between the laser source and the welding site numerous times.
