Abstract: The invention concerns a gas generator with a fuel gas filter for the pyrotechanical production of gases from a propellant charge. A separator chamber is disclosed that is designed with annular slots for the purpose of cleaning gas contaminated with solid residue from combustion. The gases produced in the combustion chamber enter the separator chamber through tangentially arranged gas ducts. After flowing through the annular formed separator chamber, the gases flow around the frontal area of the central axially arranged center block before they reach the guidance components, which are sensitive to soiling. Subsequently, the hot gases exit by way of a jet. Through the effect of centrifugal forces, the contaminating particles are slung against the outer wall of the annularly slotted separator chamber and are held fast in its special profile.

Abstract: In a pressurized materials processing system, separation of solid particulates from a gaseous process fluid is beneficially accomplished by use of a swept orifice discharger comprised of a cylindrical housing that is closed at one end and open at the other end. The housing contains an impeller within its interior and has a selected, presized orifice in its cylindrical side wall. In operation, the solid material and gaseous fluid are received in the swept orifice discharger housing and the solid material is continuously centrifugally urged toward the housing side wall so that it separates from the gaseous process fluid and collects on the housing side wall.

Abstract: An air introduction assembly for a vehicle engine located with respect to a roof mounted air deflecting member to perform an air cleaning or contaminant separating function. The air inlet is placed in a plane substantially parallel to the surface of the deflector over which air flows during vehicle movement and opens normally to the direction of the air flow. Air passing thereover which enters the inlet must be diverted in an arcuate path which causes contaminant particles to pass the inlet. The air inlet is partially defined by a forward peripheral edge portion offset outward from the surface of the air deflector so that a moving contaminant-laden layer of air immediately adjacent the deflector surface is excluded from entering into the inlet. Leading from the inlet is an air passage which tangentially introduces the air entering the inlet into a cylindrical separator chamber.
