Abstract
Abstract Oppositely charged electrode cones or electrode cylinders are adjustably supported so that one cone or cylinder is within the other cone or cylinder but spaced therefrom, whereby air currents attracted to and flowing through the electrostatic field have particles of impurity acquire the charge of one of the electrodes and are repelled to be collected on and adhere to the other electrode cone or cylinder. Specifically the cones are made of fiberglass and the adjacent faces of the cones are coated with fiberglass wool. The cylinders may be of larger diameter and may be made of steel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
142 words
In an apparatus for depositing and collecting impuRities from the atmosphere, a hollow outer electrode, a hollow inner electrode insertable into the outer electrode, said electrodes being adapted to be charged to opposite electric potentials thereby to create an electrically charged field between and within said hollow electrodes, and means to support said electrodes in the path of air flow from the atmosphere, said hollow electrodes being substantially frusto-conical, and the smaller end of said inner electrode being longitudinally spaced inwardly from the smaller end of the outer electrode, means to direct flow of air into the space within and between said electrodes through the smaller ends of said electrodes, a frame to support a plurality of outer electrodes, another frame to support a plurality of inner electrodes, and means for adjusting the relative longitudinal spacing between the inner and outer electrodes.
Claim 2
Dependent Claim
142 words

Claim 3
Dependent Claim
44 words
In the apparatus specified in claim 1, said frusto-conical electrodes being made of dielectric material and each having electrical conductors in the respective walls thereof, said conductors being connected to opposite terminals of an electrical charge source for opposite charges of the respective conductors.
Claim 4
Dependent Claim
37 words
In an apparatus as specified in claim 1, each of said electrodes being made of fiberglass, and fiberglass wool coating on the inner surface of the outer electrode and on the outer surface of said inner electrode.
Claim 5
Dependent Claim
23 words
In the apparatus specified in claim 1, air circulating means to create a forced flow inwardly of the smaller ends of said electrodes.
