Vertex transport

Claim 3

The method of claim 1 including incorporating said first fluid in a toroidal vortex ring by ejecting, simultaneously, into said second fluid, a mass of blanket fluid from a central opening and a mass of first fluid from an opening surrounding and closely spaced from said central opening.

Claim 4

The method of claim 2 wherein said central opening is circular and said surrounding opening is annular.

Claim 5

The method of claim 2 including the step of continuing to eject said blanket fluid after complete ejection of said mass of first fluid.

Claim 6

The method of claim 1 wherein said first fluid is discharged into an ambient fluid, and said ambient fluid supplies said blanket fluid.

Claim 7

The method of claim 1 wherein all said fluids are gases.

Claim 8

The method of claim 6 wherein said first fluid is a pollutant-bearing gas and said ambient fluid is air.

Claim 9

Apparatus for enclosing a first fluid in a blanket fluid for discharge in a vortex through an outer fluid comprising a source of said blanket fluid including a central port, a source of said first fluid including a port surrounding and closely spaced from said central port, and an intermittent ejector for pulsedly and simultaneously ejecting a predetermined mass of blanket fluid from said central port and a predetermined mass of first fluid from said surrounding port.

Claim 10

Apparatus for enclosing a first fluid in a blanket fluid for discharge in a vortex through an outer fluid comprising a source of said blanket fluid including a central port, a source of said first fluid including a port surrounding and closely spaced from said central port, and an intermittent ejector for pulsedly and simultaneously ejecting a predetermined mass of blanket fluid from said central port and a predetermined mass of first fluid from said surrounding port.

Claim 11

The apparatus of claim 8 including an interruptor for disconnecting said surrounding port from said outer fluid except during ejection of said fluid masses.

Claim 12

The apparatus of claim 9 wherein said blanket fluid source comprises a blanket fluid chamber communicating with said central port, said first fluid source comprises a first fluid chamber communicating with said surrounDing port, and said ejector comprises a first piston movable in said blanket fluid chamber, a second piston movable in said first fluid chamber, and drive means for driving said pistons simultaneously into said chambers toward said ports to eject simultaneously said predetermined masses of said fluids.

Claim 13

The apparatus of claim 10 including structure for closing communication into said first fluid chamber during ejection of said fluids.

Claim 14

Apparatus for enclosing a first fluid in a blanket fluid for discharge in a vortex through a second fluid comprising a source of first fluid, a source of blanket fluid, a wall carrying a flow separating edge for flow of said first fluid from said wall at the edge, a flow directing element for directing a stream of said first fluid in a course along said wall, past said edge, and away from said wall, said stream in its course away from said wall being contiguous with said second fluid, and a second flow directing element for directing a discharge of said blanket fluid into a course interposed between said first and said second fluids.

Claim 15

Apparatus for enclosing a first fluid in a blanket fluid for discharge in a vortex through a second fluid comprising a source of first fluid, a source of blanket fluid, a wall carrying a flow separating edge for flow of said first fluid from said wall at the edge, a flow directing element for directing a stream of said first fluid in a course along said wall, past said edge, and away from said wall, said stream in its course away from said wall being contiguous with said second fluid, and a second flow directing element for directing a discharge of said blanket fluid into a course interposed between said first and said second fluids.
