Abstract
A gas purification apparatus has a housing with an inlet end having an inlet port for gas supply to an interior chamber, and an opposite, outlet end having an outlet port for exit of purified gas from the chamber. The housing is of generally cylindrical shape with a central axis, and the inlet and outlet ports are offset from the central axis towards a lower portion of the housing. A purification medium fills at least the majority of the chamber. The internal wall of the chamber is cylindrical along part of the length of the housing extending from the outlet end, and has a rounded or part-spherical inlet portion extending from the inlet port to the cylindrical part of the internal wall.

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.
