Abstract
Abstract A discharge electrode for use in electrostatic precipitators is provided wherein the surface of the electrode is formed of alternate sections of conductive and nonconductive materials supported on an electrically conductive inner rod. When the electrode is in use, corona formation occurs at the interface between the conductive and nonconductive sections.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
A discharge electrode comprising, an electrically conductive rod and an outer sheath formed of alternately arranged electrically conductive and electrically non-conductive sheath sections encasing said rod, said sheath sections being positioned in contact with said inner rod and in contact with each other; said rod being a substantially straight longitudinally extending member; said electrically conductive and non-conductive sections being generally annular members alternately arranged coaxially of each other along the longitudinal axis of said rod; and the external diameter of said non-conductive sections exceeding the external diameter of said conductive section and the length of each of said conductive sections exceeding the length of each of said non-conductive sections.
Claim 2
Dependent Claim
109 words
A discharge electrode comprising, an electrically conductive rod and an outer sheath formed of alternately arranged electrically conductive and electrically non-conductive sheath sections encasing said rod, said sheath sections being positioned in contact with said inner rod and in contact with each other; said rod being a substantially straight longitudinally extending member; said electrically conductive and non-conductive sections being generally annular members alternately arranged coaxially of each other along the longitudinal axis of said rod; and the external diameter of said non-conductive sections exceeding the external diameter of said conductive section and the length of each of said conductive sections exceeding the length of each of said non-conductive sections.
Claim 3
Dependent Claim
106 words
A discharge electrode comprising, an electrically conductive rod and an outer sheath formed of alternately arranged electrically conductive and electrically non-conductive sheath sections encasing said rod, said sheath sections being positioned in contact with said inner rod and in contact with each other; said rod being a substantially straight longitudinally extending member; said electrically conductive and non-conductive sections being generally sector-shaped members alternately arranged circumferentially about the longitudinal axis of said rod; and said electrically non-conductive sectors describing a smaller angle than said electrically conductive sectors, with respect to said rod, and extending a greater distance radially outwardly from said rod than said electrically conductive sections.
Claim 4
Dependent Claim
106 words
A discharge electrode comprising, an electrically conductive rod and an outer sheath formed of alternately arranged electrically conductive and electrically non-conductive sheath sections encasing said rod, said sheath sections being positioned in contact with said inner rod and in contact with each other; said rod being a substantially straight longitudinally extending member; said electrically conductive and non-conductive sections being generally sector-shaped members alternately arranged circumferentially about the longitudinal axis of said rod; and said electrically non-conductive sectors describing a smaller angle than said electrically conductive sectors, with respect to said rod, and extending a greater distance radially outwardly from said rod than said electrically conductive sections.
