The Use of Electronic Devices in the Glass Industry

JSGT 1951 V35 T230-T240

The valuable features, applications and further uses of electronic methods in the glass industry are summarised. The uses of PbS, lead selenide and lead telluride cells, and of thermopiles and bolometers, all in conjunction with suitable electronic equipment, are illustrated by reference to :- (l) Temperature measurements on glass forming rolls and plate glass casting tables. (2) Infra-red transmission measurements on a sheet glass at temperatures ranging from 50° to 1400°. (3) Measurements of reflection spectra at wavelengths ranging from 4 /1 to 13 /1 on fused silica, Pyrex, Chance Bros. ON.19 glass, X-ray lead glass and on a sheet glass.
