Abstract: The invention relates to a method of manufacturing optical fibres in which a quartz glass tube is coated on the inside with core material, the assembly is contracted to form a solid rod which is then inserted into a quartz glass tube, after which the assembly is drawn. The last tube is thermally treated to eliminate contaminations at the surface which may detrimentally influence the tensile strength of the ultimate fibre.

Abstract: A glazing unit for removing mold separation marks from press molded glassware includes a refractory oven, sized to snugly surround a vertical stack of ware to be treated. The oven is open at the bottom and at the top to permit movement of the ware therethrough. Tangentially arranged inclined nozzles at the upper end of the oven create a downwardly directed swirling blanket of hot gases around the periphery of the stack of ware and these gases exit through passageways at the bottom of the oven. An electric current may be conducted to the periphery of the ware through the hot gases to assist in the remelting of the rim of the ware and means are provided to advance the ware through the oven by adding one piece at a time to the bottom of the stack while removing one piece at a time from the top of the stack.

Abstract: The invention relates to a method of elimination discontinuities in a quartz tube by means of a thermal treatment. According to the invention a plasma burner is used for this treatment in which the quartz tube is passed through an electrical coil being part of this plasma burner, while an inert gas is direct to the quartz tube. As a result the quartz tube is locally heated while mechanical discontinuities can disappear and possible impurities can be removed from the quartz. The part of the quartz tube in which the impurities have accumulated is removed later, if necessary.

Abstract: The present invention was developed to provide an improved process for retaining the substantially pristine state of glass articles, particularly thin-walled, lightweight glass containers. In particular, this invention relates to a process of maintaining the strength of glass containers formed from molten glass gobs as encountered especially in conventional press-and-blow or blow-and-blow equipment of individual section glass machines, the process comprising initially forming a formed portion from each of said gobs, fully forming the remaining portions of the containers from said gobs, grasping the thus-formed containers only at the initially formed portion and transferring them to a cradle device whereby said containers are held in spaced relationship to each other and held free of contacting any solid or unsmooth surface including stoplates, bearing surfaces, conveying belts and the like, partially cooling immediately following the formation of said containers, moving said cradle device with the accompanying containers to an annealing zone whereby the containers including the bottom walls thereof are subjected to a controlled rate of cooling therein, and finally rapidly cooling said containers to ambient temperature while still being gripped only at the initially formed portions thereof.
