Abstract |
Composi,tzlons for eye protective glass filters have been developed for use in
weMing and other industrial operations where the eye is explosed to ultra-violJet and
infra-red radiations as well as to intense light and glare. The desz1re~d absorptvon
characteristics wer:e obtained by using oxides of iron, nickel, cop,per, chromium and
cerium and (he resulting glasses conform to the British Standard BS 679-1959.
They are similar to the filters already in use. The g~asses dwetop1e1d for gas welding
have the additional advantages of abs011bing the heat rays to a larger ,eXtent and of
being made wholly of glass instead of conta~ning dyed plastic inter-layer. |
