Abstract
Abstract A mesh electrode for a c.r.t. display device consists of a number of coplanar portions of mesh insulated from each other and secured to a support plate by means of a refractory compound incorporating particles larger than the pitch of the mesh. These particles space the mesh away from the support plate and allow the electrode to be easily fabricated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
49 words
A mesh electrode having a plurality of electrically mutually insulated segments and which is mounted on a supporting member by means of a refractory compound which incorporates particles which are larger than the pitch of the mesh so as to hold the mesh electrode away from the supporting member.
Claim 2
Dependent Claim
49 words
A mesh electrode having a plurality of electrically mutually insulated segments and which is mounted on a supporting member by means of a refractory compound which incorporates particles which are larger than the pitch of the mesh so as to hold the mesh electrode away from the supporting member.
Claim 3
Dependent Claim
29 words
A mesh electrode as claimed in claim 1 and wherein the supporting member is metal, and both the refractory compound and the particles are composed of electrically insulating materials.
Claim 4
Dependent Claim
17 words
A mesh electrode as claimed in claim 1 and wherein the refractory compound is a glass cement.
Claim 5
Dependent Claim
17 words
A mesh electrode as claimed in claim 1 and wherein the particles are composed of refractory material.
Claim 6
Dependent Claim
19 words
