Abstract
Abstract A nozzle having a plurality of radially extending and upwardly diverging fingers provides narrow slots that divide a flow of hot gases and vapors into long, thin streams to increase the entrainment ratio of ambient air to hot gases in arrangements for eliminating visible air pollution by vapor condensation.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
An entrainment nozzle for breaking up a column of hot gases into a plurality of ascending narrow walls of gases comprising means for dividing said column of gases into separate streams and diverting each of said streams to and through a corresponding one of a plurality of horizontal slots extending radially from the original direction of flow of said column, a pair of opposed vanes mounted for pivotal movement between a horizontal closed position and a vertical open position for regulating the widths of said slots to accomodate varying rates of gas flow, each said vane being pivotally mounted on an axial rod, which rod is connected to rack and pinion means for actuation of the vane between a horizontal and a vertical orientation upon movement of the rack with respect to the pinion.
Claim 2
Dependent Claim
134 words
An entrainment nozzle for breaking up a column of hot gases into a plurality of ascending narrow walls of gases comprising means for dividing said column of gases into separate streams and diverting each of said streams to and through a corresponding one of a plurality of horizontal slots extending radially from the original direction of flow of said column, a pair of opposed vanes mounted for pivotal movement between a horizontal closed position and a vertical open position for regulating the widths of said slots to accomodate varying rates of gas flow, each said vane being pivotally mounted on an axial rod, which rod is connected to rack and pinion means for actuation of the vane between a horizontal and a vertical orientation upon movement of the rack with respect to the pinion.
Claim 3
Dependent Claim
25 words
The nozzle of claim 1 wherein said slots are defined by a plurality of arcuately spaced radially extending fingers having internal spaces and top openings.
Claim 4
Dependent Claim
31 words
The nozzle of claim 2 wherein the fingers are equally arcuately spaced and wherein a cylindrical base upon which said fingers are mounted serves to admit hot gases to the nozzle.
Claim 5
Dependent Claim
48 words
The nozzle of claim 2 wherein said diverting means includes inwardly and upwardly extending panels arranged between adjacent ones of said fingers and a conical member with its apex pointing downwardly with respect to said gas stream to divert the gases into the internal spaces of said fingers.
Claim 6
Dependent Claim
25 words
The nozzle of claim 2 wherein each of said fingers has a pair of parallel, opposed generally triangular side walls defining a wedge-shaped space therebetween.
Claim 7
Dependent Claim
21 words
The nozzle of claim 1 wherein there are at least three of said slots, and said slots are equally arcuately spaced.
