Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
170 words
An electrostatic precipitator for extracting particles and other contaminants from a gaseous stream, said precipitator comprising: A a collector electrode tube; B a discharge electrode structure disposed in said tube, said structure including a column whose center axis is coincident with the axis of the tube, said column being formed of dielectric material and having a cross-sectional geometry that defines a circular series of longitudinally-extending niches, and a circular array of fine gauge wires supported between the ends of the column, each wire being suspended within a respective niche, whereby the wires are electrostatically isolated from each other; and C means to impress a high voltage between the array of wires and the facing surface of the collector tube to create an electrostatic field in the annular region between the discharge electrode and the tube to ionize the contaminants in the gaseous stream passing therethrough, the surfaces of the niches acquiring bound electrostatic charges whereby the voltage gradient established between the discharge electrode structure and the tube is substantially uniform.
Claim 2
Dependent Claim
170 words
An electrostatic precipitator for extracting particles and other contaminants from a gaseous stream, said precipitator comprising: A a collector electrode tube; B a discharge electrode structure disposed in said tube, said structure including a column whose center axis is coincident with the axis of the tube, said column being formed of dielectric material and having a cross-sectional geometry that defines a circular series of longitudinally-extending niches, and a circular array of fine gauge wires supported between the ends of the column, each wire being suspended within a respective niche, whereby the wires are electrostatically isolated from each other; and C means to impress a high voltage between the array of wires and the facing surface of the collector tube to create an electrostatic field in the annular region between the discharge electrode and the tube to ionize the contaminants in the gaseous stream passing therethrough, the surfaces of the niches acquiring bound electrostatic charges whereby the voltage gradient established between the discharge electrode structure and the tube is substantially uniform.

Claim 9
Dependent Claim
15 words
A precipitator as set forth in claim 1, wherein said column is formed of polystyrene.
