Abstract

1,242,990. Pipes. ATOMIC POWER CONSTRUCTIONS Ltd. 16 July, 1968 [18 July, 1967; 8 May, 1968], Nos. 9575/71 and 9576/71. Divided out of 1,241,413. Heading F2P. Air ducting is fabricated from two L-shaped resin-bonded fibre mouldings, Fig. 1, secured at rebated surfaces 11, 12 by riveting, stapling or gluing. Lengths of ducting are joined by slipping over a metal or moulded connector (Figs. 4 and 5, not shown). This connector may be angled (Fig. 6, not shown). It is described how duct sizes which are multiples of the smallest size may be used in parallel to provide a continuous range of flow areas (Figs. 7-12, not shown). The mouldings may be made fireresistant by painting or impregnating with suitable materials.
