Zusammenfassung:	1,151,949. Annealing glass. LIBBEY-OWENS-FORD GLASS CO. 21 Aug., 1967 [22 Aug., 1966], No. 38416/67. Heading C1M. Glass sheets R are continuously annealed by passing through a lehr on rollers 27 and the temperature differential across the sheet is sensed by an infra-red detector 35 reciprocates transversely of the motion of the sheet by a reversible motor through gears 31 and controlled by abutments 112, 113 engaging limit switches. The results of the scanning are presented on a pen recorder 147 and are used to control the temperature differential across the sheet to give the required stress differential therein. The detector 35 lies in a fluid-filled trough in order to keep it cool and thus stabilize it.
