Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
30 words
A static discharge member as in claim 1 wherein said hole includes an enlarged portion at the distal end where the resistance material is in contact with said discharge means.
Claim 2
Dependent Claim
29 words
A static discharger as in claim 2 wherein said conductive discharge means comprises a transverse pin extending through the enlarged portion of the hole to contact the resistive material.
Claim 3
Dependent Claim
102 words
A static discharger comprising a retainer base adapted to be secured to an object to be discharged, an elongated electrically nonconductive discharge member adapted to be mounted to said base, said member having an axial longitudinal hole, a metallic, electrically conductive corona discharge pin extending through said discharge body and said hole with at least one sharp pointed end extending therefrom at a position spaced from the retainer base, and a resistive means disposed within and filling said hole throughout the length thereof and serving to electrically connect said pin to said base to provide a discharge path for said static discharger.
Claim 4
Dependent Claim
19 words
A static discharge member as in claim 4 wherein said hole includes an enlarged portion at the distal end.
Claim 5
Dependent Claim
29 words
A discharge member as in claim 4 wherein said discharge member includes at least one transverse opening filled with said resistive material to provide electrical connection to said base.
