Abstract: For interrupting the transmission of vibration along a conduit, e.g., a pipeline or silencer shell, while structurally connecting the parts together, a vibration damping device is interposed in the conduit, the vibration barrier/structural connector comprising a series of spaced washer-shaped plates with vibration damping cushions sandwiched between adjoining plates, the plates being fastened together in couples alternately at their outer and inner peripheries to provide a multiple cantilever connector between the portions of the conduit to which the end plates of the connector are secured.

Abstract: The pulsating gas flow tube is open to the surrounding acoustic surge chamber through a relatively large opening at the inlet end of the snubber and perforations in the tube, and the chamber is filled with acoustically penetrable media which broadens the frequency range over which the chamber is acoustically effective. To handle moisture-laden gases without loss of acoustical efficiency, a coalescing element is provided to collect and remove moisture and prevent the accumulation thereof in the media.
