Abstract

1,168,422. Chimney linings. TAKUMA KIKAN SEIZO K.K. 1 March, 1968, No. 10121/68. Heading F4J. [Also in Division F1] The lower part 4 of a chimney 1 is provided, opposite a waste gas inlet pipe 14 with a spaced heat insulating and sound absorbing lining 11 having a perforated metal inner surface 12. Low-frequency noise carried by the gases is further reduced by an acoustic filter formed by a reduced diameter portion 5 located above the part 4, and a resonance sound silencer formed from blind channels 22 covered by a perforated plate 18 located below it.
