Abstract
A flexible conduit system having a corrugated flexible conduit, a first tapered member disposed in the flexible conduit at the inlet end or close to the inlet end of the corrugated flexible conduit and a second tapered member disposed in the flexible conduit at the outlet end or close to the outlet end of the corrugated flexible conduit. The first tapered member at the inlet end converges and centers the flow of gases through the flexible conduit and the second tapered member at the outlet end channels the flow of gases away from the corrugations of the corrugated flexible conduit thereby reducing noise in the flexible conduit system.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
