Abstract
An induction plasma torch comprises a tubular torch body, a tubular insert, a plasma confinement tube and an annular channel. The tubular torch body has upstream and downstream sections defining respective inner surfaces. The tubular insert is mounted to the inner surface of the downstream section of the tubular torch body. The plasma confinement tube is disposed in the tubular torch body, coaxial therewith. The plasma confinement tube has a tubular wall having a thickness tapering off in an axial direction of plasma flow. The annular channel is defined between, on one hand, the inner surface of the upstream section of the tubular torch body and an inner surface of the insert and, on the other hand, an outer surface of the tubular wall of the plasma confinement tube. The cooling channel carries a fluid for cooling the plasma confinement tube.

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.
