Abstract
A particle feeding device and method for fluidized bed coaters that has no moving parts. It preferably provides for constant flow of purge gas into the fluidized bed coater and has a feedback control means for monitoring and precisely controlling the flow of particles into the coater. The particle feeding device includes a supply of granular material in communication with a generally horizontal passageway and a delivery conduit for feeding granular material into a desired location, such as a fluidized bed coater. The amount of granular material remaining in the supply is periodically determined and pulses of gas are periodically discharged through said generally horizontal passageway so as to blow granular material into said delivery conduit in a manner so as to feed the precise amount of granular material for predetermined periods of time.

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.
