B., 5, Waldeck Road, West Ealing, London. Sept. 25, 1930, Nos. 28756/30 and 16358/31. [Class 56.] Strengthening glassware.-Relates to a process for treating glassware during manufacture, in order to increase the resistance of the ware to thermal or mechanical shocks, by rounding- off or filling-in the minute discontinuities or flaws which occur in the surface of the glass. According to the invention, the treatment may be effected either by applying to the surface of the glass, under suitable temperature conditions such as exist in an annealing leer, an acid substance or medium capable of attacking the glass, or by applying a substance which fuses readily to the glass. In one method of carrying out the invention, sulphur is introduced into the leer and is converted into sulphur dioxide which attacks the glass. For this purpose, a liquid, such as oil containing sulphur in suspension, may be applied to the conveyer or endless belt B, Fig. 1, of a leer A<1> which is preferably of the type described in Specification 250,201, [Class 51 (ii), Furnaces and kilns for applying &c.]. The liquid is contained in a trough C which is disposed transversely to the belt B outside the leer. A roller D dips into the liquid and also makes contact with the belt B. Alternatively, powdered sulphur in regulated charges may be sprayed or projected under pressure into the leer tunnel. The powdered sulphur is placed in a hopper E, Fig. 4, whence it is fed by a rotary measuring-device F into a chamber or receptacle H. From this chamber the sulphur is blown through a pipe H<1> into the interior of the leer tunnel by means of compressed air. The admission of compressed air. to the chamber H is controlled by a valve J mounted in the spindle of the measuring-device F, and both are rotated by a motor G through reduction gearing G<1>. In this way, regulated charges of sulphur are blown into the leer at regular intervals.
