Abstract
A removable heat inducer may be used in either a heated regulator or a fluid heater. The removable heat inducer has various embodiments. In one embodiment, helical threads are formed on the outside surface of the inducer. The inducer expands when heated causing the crest of the threads to come into contact with the inside surface of a heating chamber to form a spiral fluid passageway which promotes better heat exchange between the fluid and the heating element. In a first alternative embodiment of the inducer, a series of walled partitions and slots are formed on the outside surface of the inducer, which likewise expand and contact the inside surface of the heating chamber to form a dead head flow passageway. Again, the purpose of the passageway is to promote efficient heat exchange. In a second alternative embodiment of the removable heat inducer, a plurality of rods are placed in the heating chamber to promote heat exchange. The spaces between the rods form passageways for the fluid. The removable heat inducer may be used in a heated regulator or a fluid heater.

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.
