PCT No. PCT/GB93/01664 Sec. 371 Date Jan. 30, 1996 Sec. 102(e) Date Jan. 30, 1996 PCT Filed Aug. 5, 1993 PCT Pub. No. WO95/04708 PCT Pub. Date Feb. 16, 1995Quenching apparatus (12) for use in glass heat treatment apparatus comprises a plurality of air flow amplifiers (32) carried on manifolds (26, 28) and arranged in arrays to direct cooling air onto both surfaces of glass (16) being treated. Compressed air is supplied to the manifolds (26, 28) from air receivers (22) charge by a compressor (20) the compressed air flow being controlled by a control valve (24). Air flow received by the air flow amplifiers (32) from the manifolds (26, 28) is amplified to supply a flow of cooling air directed towards the sheet of glass (16). The air flow amplifiers (32) may be air ejectors. A furnace (10) is provided to heat the glass (16) and a conveyor is provided to carry the glass (16) from the furnace (10) to the quenching apparatus. |
