Abstract
A protective flange is provided for the protection of a protrusion or valve on the surface of a tank car. The flange has an inner arcuate wall and an outer deflection portion for receiving impacts. The inner wall is annular and spaced from the protrusion to provide for mounting over the protrusion without cutting into the tank car. The outer portion includes longitudinally extending slope portions and vertical side walls welded to the tank car surface. The flange is tapered to deflect impacts received at the sides of the flange. The outer deflection portion and the inner wall define a closed space surrounding the protrusion or valve. Steam connections may be made to the flange to introduce steam into the closed space for heating the valve.

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.
