Abstract
Abstract A corona discharge device having a coronode of the type including a wire electrode coated with a fractureable dielectric sleeve for example, glass. Electrical contact is made to the wire via a conductive member forcibly attached or crimped to the sleeve to fracture it sufficiently to permit direct contact between the wire and the member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
42 words
A corona discharge device comprising a coronode, said coronode including an inner wire coated with a frangible dielectric and a conductive member carried on at least one end of said coronode, said member fracturing said dielectric material to contact said inner wire.
Claim 2
Dependent Claim
42 words
A corona discharge device comprising a coronode, said coronode including an inner wire coated with a frangible dielectric and a conductive member carried on at least one end of said coronode, said member fracturing said dielectric material to contact said inner wire.
Claim 3
Dependent Claim
22 words
The combination recited in claim 1 wherein said member comprises a metal sphere having a groove formed therein to straddle said coronode.
Claim 4
Dependent Claim
11 words
The combination recited in claim 1 wherein said dielectric is glass.
Claim 5
Dependent Claim
22 words
The combination recited in claim 3 wherein said member comprises a metal sphere having a groove formed therein to straddle said coronode.
Claim 6
Independent Claim
56 words
The method of making electrical contact to a elongated wire coated with a frangible dielectric comprising the steps of partly surrounding said dielectric with a conductive compressible member, and applying a force to said member to compress it onto said dielectric and fracture said dielectric to result in direct contact between said member and said wire.
Claim 7
Independent Claim
56 words
The method of making electrical contact to a elongated wire coated with a frangible dielectric comprising the steps of partly surrounding said dielectric with a conductive compressible member, and applying a force to said member to compress it onto said dielectric and fracture said dielectric to result in direct contact between said member and said wire.
