Abstract
Liquid and/or particle-shaped impurities are precipitated from a stream of gas, for example, from a stream of gas that originates from a crankcase of an internal combustion engine and is directed to the engine's intake side. The stream of gas is passed through a gas discharge section between two electrodes. The stream of gas is passed between an emission electrode which is formed by electrode tips and an opposing electrode at a distance therefrom. A direct voltage which exceeds the breakdown voltage is applied to the electrodes using a direct current high voltage source, and the current which occurs over the gas discharge section between the electrodes is limited. A stable low energy direct current plasma is formed in the space between the two electrodes. The impurities are electrically charged and attracted to the opposing electrode by means of electrical field forces.

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.
