TL;DR: In this paper, a diffuser is used to disperse a gaseous stream wherein the apparatus is formed as a single integral unit, having an internally located supply passage, a gas exhaust passage surrounding the supply passage and a plurality of spaced apart annular openings communicating the ambient with the exhaust passage through the outer housing wall.

TL;DR: An air diffuser includes a main body and an air diffusing baffle for hair styling as mentioned in this paper, where the main body has an upstream end with an air inlet and a coupler for attachment to a hair blower, and a downstream end with air outlet for delivery of air to a user.
Abstract: An air diffuser includes a main body and an air diffusing baffle for hair styling. The main body has an upstream end with an air inlet and a coupler for attachment to a hair blower, and a downstream end with an air outlet for delivery of air to a user. The air diffusing baffle has an air baffling surface. The air baffling surface is movable relative to the main body for varying effective level of baffling to an air stream from the air inlet portion.

07 Jul 2000TL;DR: In this paper, a gas diffuser is constructed and arranged to disperse gas into a aeration vessel of a water treatment assembly from a blower, where the diffuser includes main pipes, branch pipes extending between the main pipes and containing gas discharge ports.
Abstract: The invention concerns a gas diffuser constructed and arranged to disperse gas into a aeration vessel of a water treatment assembly from a blower. The gas diffuser includes main pipes, branch pipes extending between the main pipes and containing gas discharge ports, wherein the branch pipes have a smaller cross-sectional area than the cross-sectional area of the main pipes. The gas discharge ports are further sized, constructed and arranged to reduce the possibility or likelihood of sludge from blocking the ports or entering the branch pipes. This object is achieved either by placement of the ports on the bottom sides of the branch pipes or, alternatively, by construction of the ports to include conduit members, themselves having an arrangement of openings or coverings to prevent or reduce the likelihood of sludge from blocking the ports or entering the branch pipes.
