Abstract

1358775 Exhaust silencers BBC BROWN BOVERI & CO Ltd 7 June 1972 [9 June 1971] 26526/72 Heading F1B [Also in Division H1] A silencer, for use with a gas-blast circuit breaker, comprises a cylindrical elastic rubber diaphragm 5, having a large number of small pores which open substantially only if the diaphragm is expanded, secured between end plates 6 and 7 to define a chamber into which compressed gas is vented from the circuit breaker exhaust valve 4. A wire cage or grid structure 8 prevents the diaphragm from being over expanded. (For Figure see next page)
