The outer wall 1 may be of fabric, paper, pliable metal, rubber, thin leather, or cellulose acetate &c. formed from sheet material or moulded. The lining 2 may be of rubber, cellulose acetate, or spring steel &c. coiled &c. to form a tube, as a single complete tube, or as two or more co-axial tubes and may be cemented &c. to the wall 1. The air duct 3 may be of plastic, metal, or glass and may be partly located between the wall 1 and the lining or in a groove or pocket in the lining; it may be cemented to the wall or lining or to both. The wall, or a single-ply lining may be formed by spraying or painting. Specification 611,060 is referred to.
