Abstract

1399932 Whistles SOC ANON DES ETABS NEU 3 Aug 1972 [4 Aug 1971] 36385/72 Heading G5J [Also in Division B1] A whistle, designed to vibrate filter bags 4a to clean them, comprises an inlet nozzle 61 and a resonator tube 62 providing an air column of resonant frequency 800-1000 c/s., arranged on opposite sides of a flared horn 63, which directs the sound produced by supplying compressed air to nozzle 61 towards the bags. Air is fed from reservoir 7 through quick-opening valve 64 which may be operated pneumatically or electrically.
