Abstract
1439484 Air ducting BROWN BOVERI & CIE AG 29 Aug 1973 [15 Sept 1972] 40712/73 Heading F2P An air duet is made of a laminate material comprising a layer of rigid foamed material 3 between two parallel metal, e.g. aluminium layers, the laminate before being bent into a rectangular sectioned duct being provided with impressed grooves 7 to form the corners of the duct. A further metal layer 8 may be secured over the joint formed by the bent material, e.g. by an adhesive. In Fig. 3 two such ducts of different cross-sections are united by an air interchanger 9.
