ABSTRACT:
It is desirable to have a camera tube in which the signal plate has a low capacity. This may be achieved by taking a conductor from the signal plate through the glass faceplate. Previous methods of manufacturing a faceplate in which a conductor is embedded have proved unsatisfactory because of difficulty in carrying them out, and distortion and incomplete fusion of glass.
A graphite mould having a base and walls contains and supports two glass blocks and a conductor and permits a degree of fluidity of the glass to be obtained which gives good fusion.
