Abstract

1287071 Aerating liquids COMMISSARIAT A L'ENERGIE ATOMIQUE 5 Jan 1971 [5 Jan 1970] 378/71 Heading B1C [Also in Division El] A nozzle for mixing air and water, accelerating the mixture and forming it into a jet comprises a nozzle 6 into which air is pumped via pipe 10 and holes 12 to pass through holes 9 in element 8 to mix with water pumped via pipe 13 into element 8. Venturi 16 accelerates the mixture and forms a jet.
