An apparatus for deagglomerating and aerosolizing particulate matter such as powders, the apparatus including a rotatable turntable having a plurality of circumferentially spaced wells adapted to contain a powder. A pair of conduits are fluidly connected to the turntable wells so that powder from the wells is inducted and drawn to two nozzles so that the powder is entrained in the gas flow exiting each nozzle. Furthermore, the nozzle outlets are aligned and spaced apart from each other, but positioned to direct their particle entrained gas flow in the opposite and facing direction to one another so that the flow from each nozzle impinges upon the flow from the other nozzle to further air mill and deagglomerate the individual powder particles.

Apparatus for deagglomerating and disseminating powders and particulate matter

A quick disconnect coupling device formed from a female coupling portion a male portion for mating therewith. The outside diameter of the male portion is equal to the inside diameter of the female portion from the axial outer end of the male coupling to a point less than the total distance of penetration and a reduced outside diameter axially inward thereof. Each coupling portion has a valve to close the portions when they are disconnected. The coupling portions are configured to have a difference between the inside diameter of the female coupling portion and the reduced diameter of the male coupling. The female coupling portion is free to rotate about a point of maximum penetration by the male coupling portion to permit quick disconnection upon application of force to the outer end of either of the coupling portions. The edge of the male coupling portion may be tapered inwardly to assist in the rotation.
