Abstract
Abstract A swirl chamber comprises a housing, which at its shell or side wall is connected to at least one tubular port having a center line which is approximately at right angles to and spaced from the axis of the housing. In the improved swirl chamber at least two tubular ports extend through the shell or side walls and with respect to radii of said housing which intersect said ports at their inner ends are inclined in the same sense in a peripheral direction of the housing, the housing is closed at opposite ends by end plates or end walls, which are intersected by the axis of the housing, and an inlet nozzle is provided in one end plate and a discharge tube in the other.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
225 words
An apparatus comprising: means for dispersing a dispersant material in a fluid and removing dispersant material therefrom having a particle dimension exceeding a predetermined value including, a swirl chamber including a peripheral wall and opposite first and second end walls; a dispersant material feed conduit communicating with said swirl chamber through said first end wall; a fluid feed conduit communicating with said swirl chamber through a port in said swirl chamber peripheral wall and at an angle having a component tangential to said swirl chamber whereby to import rotation to fluid entering said swirl chamber through said fluid feed conduit; a centrifuging chamber axially spaced from and approximately coaxial with said swirl chamber and including a peripheral wall; a connecting conduit approximately coaxial with said chambers and extending from and communicating with said swirl chamber through said second end wall and projecting into said centrifuging chamber and terminating in an open inner end; a first discharge conduit approximately coaxial with said connecting conduit and having an inner end axially spaced from said connecting conduit inner end and extending axially outwardly from said centrifuging chamber; and a second discharge conduit communicating with said centrifuging chamber through said peripheral wall thereof in a direction with a component tangential to said centrifuging chamber to direct dispersant particles having dimensions exceeding a predetermined value through said second discharge conduit.
Claim 2
Independent Claim
225 words
An apparatus comprising: means for dispersing a dispersant material in a fluid and removing dispersant material therefrom having a particle dimension exceeding a predetermined value including, a swirl chamber including a peripheral wall and opposite first and second end walls; a dispersant material feed conduit communicating with said swirl chamber through said first end wall; a fluid feed conduit communicating with said swirl chamber through a port in said swirl chamber peripheral wall and at an angle having a component tangential to said swirl chamber whereby to import rotation to fluid entering said swirl chamber through said fluid feed conduit; a centrifuging chamber axially spaced from and approximately coaxial with said swirl chamber and including a peripheral wall; a connecting conduit approximately coaxial with said chambers and extending from and communicating with said swirl chamber through said second end wall and projecting into said centrifuging chamber and terminating in an open inner end; a first discharge conduit approximately coaxial with said connecting conduit and having an inner end axially spaced from said connecting conduit inner end and extending axially outwardly from said centrifuging chamber; and a second discharge conduit communicating with said centrifuging chamber through said peripheral wall thereof in a direction with a component tangential to said centrifuging chamber to direct dispersant particles having dimensions exceeding a predetermined value through said second discharge conduit.
Claim 3
Dependent Claim

Claim 13
Dependent Claim
19 words
The apparatus of claim 1 wherein the end of said connecting conduit within said centrifuging chamber is outwardly flared.
Claim 14
Dependent Claim
22 words
The apparatus of claim 1 including a plurality of axially spaced coaxial centrifuging chambers in successive end-to-end communication through respective connecting conduits.
Claim 15
Dependent Claim
