PATENT: R. M. Kelso, P. V. Lanspeary, G. J. Nathan, S. J. Hill, J. J. Parham, G. Kelly, P. R. E. Cutler, M. G. Budrulhisham (Assigned to Adelaide Research & Innovation Pty Ltd). EP 1141631 B8 (PCT/AU1999/001164) filed Dec 24, 1999; published Jul 4, 2007; granted until Dec 24, 2019.A fluid mixing device (1) includes a chamber (3) and a bluff body (4) defining one end of the chamber (3). A first fluid inlet (5) is located toward an opposite end of the chamber (3) from the bluff body (4) and arranged to direct fluid toward the bluff body (4). A region substantially surrounding the bluff body (4) has a flow divider (8) defining second fluid inlet(s) (11) to the chamber (3) and mixed fluid outlets (12) from the chamber (3). A fluid flow from the first fluid inlet (5) and/or from the second fluid inlet (11) establishes a recirculating vortex system (14) within the chamber and results in a mixture of fluids from the first fluid inlet (5) and the second fluid inlet(s) (11) being directed through the mixed fluid outlets (12).Invented by R. M. Kelso, P. V. Lanspeary, G. J. Nathan, S. J. Hill, J. J. Parham, G. Kelly, P. R. E. Cutler, M. G. Budrulhisham; Assigned to Adelaide Research & Innovation Pty Ltd; Sherrard-Smith, Hugh et al. agents for inventors.http://www.patentlens.net/patentlens/patent/EP_1141631_B8/en
