Abstract
Abstract A discharge electrode assembly for use in an electrical gas precipitator has a pair of contiguous elongate wires extending between mounting means attached at one end thereof for suspending the electrode vertically within the precipitator and a pair of concentric cylindrical weights attached respectively to the other ends of the wires. Sufficient space is provided between the inner and the outer weights to permit precipitates to fall through to the bottom of the precipitator. Both weights preferably have enclosed, dome-shaped tops with respective lateral slots extending from one outer edge to the center of the tops. The slots accommodate enlarged extensions on the wire ends and permit the weights to be easily secured on the wires. The inner weight can be rotated within the outer weight to lock the wires within the slots so that accidental disconnection cannot take place during use. The wires are individually tensioned by the weights, and can continuously move longitudinally and rotationally with respect to each other to remove any adhering precipitates.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
86 words
A discharge electrode for use in an electrical precipitator for removing precipitates from gases, comprising: a pair of contiguous, elongate wires; mounting means at one end of the wires for attaching the wires to the precipitator; a pair of concentric, cylindrical weights attached respectively to the other ends of the pair of wires, said weights having sufficient space between the inner and outer cylinders to permit precipitates to pass therethrough and to permit the contiguous wires to move longitudinally and rotationally with respect to each other.
Claim 2
Dependent Claim
86 words
A discharge electrode for use in an electrical precipitator for removing precipitates from gases, comprising: a pair of contiguous, elongate wires; mounting means at one end of the wires for attaching the wires to the precipitator; a pair of concentric, cylindrical weights attached respectively to the other ends of the pair of wires, said weights having sufficient space between the inner and outer cylinders to permit precipitates to pass therethrough and to permit the contiguous wires to move longitudinally and rotationally with respect to each other.
Claim 3
Dependent Claim
44 words
A discharge electrode as set forth in claim 1, wherein the inner concentric weight is tapered inwardly from the upper end to the lower end thereof to provide more space between the pair of weights at the lower end than at the upper end.
Claim 4
Dependent Claim
53 words
A discharge electrode as set forth in claim 1, wherein the concentric weights have respective lateral slots extending upwardly from the lower ends of the weights, said slots being adapted to accommodate a lateral stabilizing bar disposed within the precipitator for preventing lateral movement of the discharge electrodes with respect to each other.
Claim 5
Dependent Claim
50 words
A discharge electrode as set forth in claim 1, wherein the means for attaching the wires to the precipitator comprises an elongate rod attached at one end thereof to the pair of wires and having an enlarged head at the other end adapted to fit into receptacles within the precipitator.
Claim 6
Dependent Claim
20 words
A discharge electrode as set forth in claim 1, wherein the concentric weights are detachably mounted on the electrode wires.
Claim 7
Dependent Claim
58 words
A discharge electrode as set forth in claim 5, wherein the wires have enlarged lower ends, and the cylindrical weights have closed tops and respective lateral slots extending from one outer edge of each top to the center thereof, said slots being adapted To accommodate the enlarged ends of the wires for mounting the weights on the wires.
Claim 8
Dependent Claim
32 words
A discharge electrode as set forth in claim 6, wherein the inner concentric weight is rotatable within the outer weight to permit the electrode wires to be secured within the lateral slots.
Claim 9
Dependent Claim
71 words
At least one discharge electrode as set forth in claim 1, in combination with an electrical precipitator comprising: a precipitator housing adapted to collect precipitates at the bottom thereof; at least one collector electrode disposed vertically within the housing in spaced relation with the discharge electrode; means for introducing gases containing precipitates into the housing and for withdrawing purified gases therefrom; and means for introducing an electrical current into the precipitator.
Claim 10
Dependent Claim
19 words
A combination as set forth in claim 8, including stabilizing means for preventing lateral movement of the discharge electrodes.
Claim 11
Dependent Claim
37 words
A combination as set forth in claim 8, including a laterally extending elongate bar disposed in the upper portion of the housing, said bar having spaced receptacles therein for receiving the mounting means on the discharge electrodes.
