Abstract

1483412 Ejectors SANTA FE INTER- NATIONAL CORP 5 Nov 1974 [6 Nov 1973] 47842/74 Heading F1E [Also in Division E1] A suction unit for removing suspension from an underwater location involves a primary nozzle 100 discharging water under high pressure into a secondary nozzle 102 so spaced from the primary nozzle 100 that the high pressure water jet emerging from the primary nozzle causes water outside the suction tube 86, 84, 72, 104, 136, 138, 140 of the suction unit to be drawn through the gap between to the nozzles and to be passed through the secondary nozzle at such a velocity that when the mixture of waters entering the secondary nozzle emerge therefrom into the suction pipe they will induce a flow of water and matter suspended therein through the pipe from the intake 86 to the discharge 140 of the pipe. The nozzle 100 can be adjustably spaced from the nozzle 102 by a distance within the range of 2 to 30 inches.
