The charge well comprises an open top chamber including side and base walls of a heat resistant material. An inlet is provided in a side wall of the chamber for receiving molten metal. A ramp is provided adjacent the side wall and an inner wall forms a central cavity. The ramp is disposed between the inner wall and the side wall. The ramp is generally inclined from an intersection with the base wall to adjacent a top surface of the inner wall. The cavity is in fluid communication with an outlet. A passage in the inner wall provides fluid communication between the inlet and the cavity. The inlet and an outlet each receives a conduit and at least one of the conduits can include an elbow joint.

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.
