Abstract: A method and system for removing particles from a particulate laden gas stream through the use of centripetal and centrifugal forces. A rotating shaft and brushes create centrifugal force upon particulates within the gas, while a centripetal force created by a pressure differential, directs the gas radially inward. The centripetal force may be created and maintained by self-pumping means driven by a rotating shaft. Rinsing means are provided for periodically rinsing particles accumulated within the bristles.

Abstract: A centripetal demister system and method for the removal of moisture from a moisture laden gas stream using both centrifugal and centripetal force to shear the moisture from a inlet gas, the centripetal force also directing the inlet gas radially inward for collecting the demisted gas. The present invention is particular useful for removal of environmentally harmful particulates contained within the moisture laden gas stream, the particulates and moisture being force against the interior of the housing by centrifugal force while the demisted gas is drawn radially inward by centripetal force.

Abstract: A marine engine exhaust system and method utilizes first and second enclosed, generally tubular chambers having generally parallel lengthwise dimensions and internal intermediate exhaust passageways spaced along the lengthwise dimension of the second chamber for circulating the exhaust gases through the first chamber, laterally through the intermediate exhaust passageway into the second chamber, along the lengthwise dimension of the second chamber and thence out of an outlet exhaust passageway which passes through the second chamber wall. An outer portion of the second chamber is integrally formed with an outer portion of the first chamber to enhance structural integrity.
