Abstract

783,055. Silencers for gaseous currents. GENEST GES. FUR ISOLIERUNGEN, W. March 1, 1956 [March 1, 1955], No. 6530/56. Class 7(2). An intake or exhaust silencer for power unit and compressor testing stations consists of sound-absorbing elements 2 disposed in a testing channel 1 and defining gas ducts 3 of constant cross-section, the cross-section of each element increasing in a direction away from the position at which a power unit to be tested will be located. As shown, the elements comprise rock wool, glass wool or asbestos covered with perforated iron plates 4, and have internal transverse walls 5.
