| Abstract: |
An electrostatic charge generator for continually providing charge carriers of a given polarity in a flow of dielectric fluid. The charge generator comprises a coaxial tube with an inner conductor wire coaxial with a hollow, cylindrical outer conductor. A D.C. potential is applied between the inner and outer conductors of the coaxial tube and a dielectric liquid, such as oil, is caused to flow therethrough. Since the intensity of the non-uniform electric field in the conductor tube is highest near the inner conductor, the electrostatic charges of the opposite polarity as the inner conductor are removed from the dielectric fluid faster than charges of the same polarity are removed at the outer conductor. This results in the dielectric fluid exiting the conductor tube carrying a charge of the remaining polarity.

First Claim:
Show all 10 claims |
What is claimed is:
1. An electrostatic charge generator for continuously providing charge carriers of a given polarity in a flow of dielectric liquid, comprising:
a. a coaxial tube comprising:
- 1. an inner conductor wire; and
- 2. a hollow, cylindrical outer conductor coaxial with said inner conductor;
b. voltage means for applying a DC potential between said inner and said outer conductor; said DC potential creating a non-uniform field the intensity of which is highest near said inner conductor;
c. a circulating dielectric liquid;
d. flow means for causing said dielectric liquid to continuously circulate through said coaxial tube at a rate to insure a turbulent flow;
e. said dielectric liquid being depleted of charges of the opposite polarity of said inner conductor more rapidly then complementary charges are removed at the outer conductor as the dielectric liquid is caused to flow through said coaxial tube, such that the dielectric liquid exiting said coaxial tube carries charges of the complementary polarity;
f. the polarity of said voltage means operable to be reversed for changing the polarity of the charges carried by said dielectric liquid and thus control the polarity of the accumulated charges; and
g. said dielectric liquid comprising a two-phase mixture consisting of from 90 to 100 percent oil and from 0 to 10 percent distilled water.
