Abstract
A filter suitable for the filtration of high temperature gasses includes a high pressure tank enclosing a chamber divided into a plurality of separate chambers by horizontally disposed rigid tube sheets. A plurality of banks of filter tubes are positioned in mutual alignment between adjacent ones of the tube sheets. Guide channels are provided on the tops and bottoms of the tube sheets for sealably mounting the filter tubes in place between the tube sheets. Fluid outlets open to the ambient through the wall of the tank between each adjacent pair of tube sheets and covers are removably secured over openings in the wall of the tank for access to the filter tubes.

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.
