Abstract
Abstract High voltage static discharge device utilizes an insulative body portion of conventional plastic material for supporting conductive discharge points and ceramic stand-offs resistant to high temperature deterioration from arcing to space the body portion from an adjacent ground. Conductive elements which are connected to the same high voltage as the points are incorporated between and isolate the body portion from the ceramic stand-offs so that all portions of the body portion are at substantially the same voltage whereas the high voltage is imposed across the stand-offs.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A high voltage electrostatic discharge device comprising: an insulative casing subject to high temperature deterioration produced by arcing, discharge means for effecting high voltage gas ionization supported in said casing and outwardly projecting therefrom, at least one insulative member having the characteristic of being resistive to high temperature arc deterioration spacing said insulated casing from an adjacent ground, a conductive element interposed between said insulated casing and each of said next adjacent insulative members and isolating the surface of said insulated casing therefrom, and means for applying a high voltage with respect to ground to said discharge means and simultaneously to each of said conductive elements, whereby said insulated casing is isolated at a uniform voltage and wherein the entire high voltage with respect to ground is imposed across said insulative members.
Claim 2
Dependent Claim
132 words
A high voltage electrostatic discharge device comprising: an insulative casing subject to high temperature deterioration produced by arcing, discharge means for effecting high voltage gas ionization supported in said casing and outwardly projecting therefrom, at least one insulative member having the characteristic of being resistive to high temperature arc deterioration spacing said insulated casing from an adjacent ground, a conductive element interposed between said insulated casing and each of said next adjacent insulative members and isolating the surface of said insulated casing therefrom, and means for applying a high voltage with respect to ground to said discharge means and simultaneously to each of said conductive elements, whereby said insulated casing is isolated at a uniform voltage and wherein the entire high voltage with respect to ground is imposed across said insulative members.
Claim 3
Dependent Claim
24 words
The electrostatic discharge device of claim 1 wherein the means for applying a high voltage with respect to ground constitutes a D.C. power supply.
Claim 4
Dependent Claim
16 words
