Abstract

1317230 Silencing gaseous flow L F BLATT and F H WIESENHOFER 9 June 1971 [15 Oct 1970] 44682/72 Divided out of 1316037 Heading F1B A silencer 44, e.g. for exhaust air, comprises a housing 46 and baffles 54 and 62 of porous material, e.g., sintered bronze or steel, porous porcelain or stone or porous plastic material. The baffles 54, 62 have part-spherical portions 57, 64 and frusto-conical portions 56, 76. A baffle 74, e.g. of felt, wire mesh, perforated metal or porous urethane, may be disposed between the baffles 54, 62.
