1411140 Nozzles H A McMASTER 30 March 1973 [14 Aug 1972] 15362/73 Heading B2F An elongated nozzle assembly comprises a plenum 18 one wall of which comprises a plurality of members 22 in abutting, sealing engagement, forming nozzles and passages communicating with the plenum. Each member 22 is L-shaped and comprises a leg 30 and a base 32, the legs 30 having outwardly displaced portions 26 having formed therein channels 24. When assembled opposed portions 26 of the legs 30 of adjacent members 22 abut so that the opposed channels 24 form nozzle passages 28 (Fig 2) communicating with a manifold 36 formed between the opposed inner ends of the legs 30, which manifold communicates with the plenum 18. The adjacent members 22 are welded together and as shown the inner members 22 are combined and comprise mirror image L-shaped members formed into a single U-shaped member. The assembly shown in Fig 1 comprises upper and lower plenums 18, 20 with nozzle assemblies, between which a sheet of glass is passed to be cooled by gas discharged from the nozzles.
