Abstract
A rail port insert is provided. The insert comprises an outer casing comprising a tubular sidewall and a base, the sidewall and base defining a spatial volume therein, the base defining an inlet passage that extends through the base and that is fluid communication with the spatial volume, and an elastomeric body having a first end and a second end, the elastomeric body disposed within the spatial volume and affixed to an inner surface of the tubular sidewall, the base, or both an inner surface of the tubular sidewall and the base. The elastomeric body comprising a flow passageway having a length extending from the first end to the second end, the first end in fluid communication with the inlet passage of the base, the second end further comprising a depth-length and defining an orifice along the depth-length, the orifice moving from a closed position in the absence of any applied pressure within the flow passageway, to an open position when pressure is applied within the flow passageway. When the rail port insert is installed in a railhead port, the inlet of the outer casing is in fluid communication with a railhead conduit. Also provided is a method of inserting the rail port insert into a railroad outlet port, and use of the rail port insert.

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.
