Abstract

Abstract Apparatus for entraining a light fluid into a denser fluid. A substantially hollow vessel is provided which is adapted to contain therein the denser fluid. A rotatable drive shaft having impeller means arranged at its lower end is disposed within the vessel. Both the drive shaft and the impeller means have interconnecting passageway means. The drive shaft passageway means includes light fluid inlet means whereas the impeller means passageway means includes aperture means transverse to and in communication with both its passageway means and the interior of the vessel. The aperture means are also spaced radially outwardly of the drive shaft. As the impeller means is rotated by means of the drive shaft, the lighter fluid is passed from the fluid inlet means through the drive shaft and out of the aperture means whereby the lighter fluid is entrained in the denser fluid within the vessel.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 244 words
Apparatus for entraining a light fluid into a denser fluid comprising: a substantially hollow closed vessel adapted to contain therein said denser fluid; a rotatable drive shaft disposed within said vessel; said drive shaft having passageway means extending longitudinally thereof; light fluid inlet means in communication with said passageway means for introducing light fluid into said passageway means; impeller means arranged at the lower end of said drive shaft and adapted to be rotated thereby, said impeller being formed from a cylindrical body and having its outer extremities imperforate and parallel to the longitudinal axis of said drive shaft; said impeller means having passageway means extending longitudinally thereof in communication with the firstmentioned passageway means; aperture means arranged transverse to and in communication with the second-mentioned passageway means for introducing light fluid from the second-mentioned passageway means into the interior of said vessel; said aperture means being spaced radially outwardly from said drive shaft and lying at an angle having its apex at the center of said cylindrical body of from approximately 100* to 120* from the initial point of contact of said cylindrical body with said denser fluid when said cylindrical body is rotated; and fluid tripping wire means disposed along the upper surface of said body between said aperture means and the point of initial contact of said body with said fluid when said impeller means is rotated for creating a turbulence when said impeller means is rotated through said denser fluid.
Claim 2
Dependent Claim 244 words
Apparatus for entraining a light fluid into a denser fluid comprising: a substantially hollow closed vessel adapted to contain therein said denser fluid; a rotatable drive shaft disposed within said vessel; said drive shaft having passageway means extending longitudinally thereof; light fluid inlet means in communication with said passageway means for introducing light fluid into said passageway means; impeller means arranged at the lower end of said drive shaft and adapted to be rotated thereby, said impeller being formed from a cylindrical body and having its outer extremities imperforate and parallel to the longitudinal axis of said drive shaft; said impeller means having passageway means extending longitudinally thereof in communication with the firstmentioned passageway means; aperture means arranged transverse to and in communication with the second-mentioned passageway means for introducing light fluid from the second-mentioned passageway means into the interior of said vessel; said aperture means being spaced radially outwardly from said drive shaft and lying at an angle having its apex at the center of said cylindrical body of from approximately 100* to 120* from the initial point of contact of said cylindrical body with said denser fluid when said cylindrical body is rotated; and fluid tripping wire means disposed along the upper surface of said body between said aperture means and the point of initial contact of said body with said fluid when said impeller means is rotated for creating a turbulence when said impeller means is rotated through said denser fluid.
Claim 3
Dependent Claim 169 words
Apparatus for entraining a light fluid into a denser fluid comprising: a substantially hollow vessel adapted to contain therein said denser fluid; a rotatable drive shaft disposed within said vessel; said drive shaft having passageway means extending longitudinally thereof; light fluid inlet means in communication with said passageway meanS for introducing light fluid into said passageway means; impeller means arranged at the lower end of said drive shaft and adapted to be rotated thereby, said impeller being formed from an elongated body of elliptical cross-section; said impeller means having passageway means extending longitudinally thereof in communication with the first-mentioned passageway means; aperture means arranged transverse to and in communication with the second-mentioned passageway means for introducing light fluid from the second-mentioned passageway means into the interior of said vessel; and said aperture means being spaced radially outwardly from said drive shaft and lying at an obtuse angle from the direction of rotation of the elliptically-shaped body, said obtuse angle having its apex at the center of said elliptically-shaped body.
Claim 4
Dependent Claim 169 words
Apparatus for entraining a light fluid into a denser fluid comprising: a substantially hollow vessel adapted to contain therein said denser fluid; a rotatable drive shaft disposed within said vessel; said drive shaft having passageway means extending longitudinally thereof; light fluid inlet means in communication with said passageway meanS for introducing light fluid into said passageway means; impeller means arranged at the lower end of said drive shaft and adapted to be rotated thereby, said impeller being formed from an elongated body of elliptical cross-section; said impeller means having passageway means extending longitudinally thereof in communication with the first-mentioned passageway means; aperture means arranged transverse to and in communication with the second-mentioned passageway means for introducing light fluid from the second-mentioned passageway means into the interior of said vessel; and said aperture means being spaced radially outwardly from said drive shaft and lying at an obtuse angle from the direction of rotation of the elliptically-shaped body, said obtuse angle having its apex at the center of said elliptically-shaped body.
