A filter cartridge assembly is disclosed, which includes a housing having a reservoir for collecting fluids entering the housing through a gas return path, a sensor located within the reservoir for detecting a fluid level therein, and a backer plate positioned within the housing adjacent an inlet port to the reservoir and including fluid management structure to shield the sensor from fluid entering the reservoir from the gas return path through the inlet port and causing a false indication of the fluid level in the reservoir.

A horizontal gas coalescing filter unit having a reduced vertical footprint includes a first housing including an inlet and an outlet, the inlet being configured for receiving a gas, including liquid condensates, under pressure. The filter unit includes an impingement head, a tuyere, and a vane separator to cause liquid condensates to separate from the gas. A second housing is positioned in fluid communication with the horizontal housing and contains a coalescing filter for receiving the gas exiting the vane separator and for further removing the liquid condensates from the gas. A gas outlet is associated with the second housing for allowing the separated, dry gas to exit the filter unit. A method for separating liquid condensates from the gas is also provided.

A method of converting a liquid hydrocarbon stream to lower boiling point hydrocarbons may include converting the liquid hydrocarbon stream to an aerosolized hydrocarbon particle stream, and subjecting the aerosolized hydrocarbon particle stream to reaction conditions. Reaction conditions may include a temperature from 25 C. to 1,000 C. and a pressure from 1 bar to 15 bar. The method may further include forming the lower boiling point hydrocarbons in the aerosolized hydrocarbon particle stream and separating the lower boiling point hydrocarbons from the aerosolized hydrocarbon particle stream. The lower boiling point hydrocarbons may comprise at least C.sub.2-C.sub.4 olefins.

An oil separator unit including an upstream member having an opening through which the blowby gas passes, a downstream member having a hit portion hit by the blowby gas, and a porous member trapping the oil mist contained in the blowby gas that has passed through the through hole. The upstream member includes an upstream surface facing a first surface of the porous member and a pair of recesses formed in substantially U-shapes along circumference portions in both end sides on an upstream surface of the upstream member, and the downstream member includes a pair of flange parts formed in substantially U-shapes so as to fit in the pair of recesses.

A rotating coalescer having an ejected coalesced liquid separating device is described. The separating device prevents re-entrainment of liquid into a stream of filtered gas. The rotating coalescer includes a rotating filter element or coalescing cone stack positioned within a rotating coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or the coalescing cone stack and the rotating coalescer housing allows for ejected coalesced liquid, such as oil, to accumulate on the inner surface of the rotating coalescer housing for drainage and allows for filtered gas, such as air, to exit through a clean gas outlet of the rotating coalescer housing.

A jet engine with a chamber which is delimited by a housing and inside of which a rotatable appliance that can be impinged by hydraulic fluid is arranged, wherein hydraulic fluid and air introduced through the housing into the chamber can be discharged from the chamber. In the area through which air and hydraulic fluid can be discharged from the chamber, the housing is embodied with a separating appliance in the area of which air and hydraulic fluid can be separated from each other, and/or a deflector appliance, by means of which air, hydraulic fluid and/or an air-oil mixture in the chamber can be guided in the direction of the area in a targeted manner, is provided upstream of the area of the housing.

A bypass flow regulator for a vacuum waste system (VWS) is disclosed. The bypass flow regulator includes a valve assembly installable in an aircraft vent line leading outside the aircraft from an onboard VWS waste tank. The vent line directs an airstream pumped from the waste tank to an external outlet under suction (from which outlet the airstream is ejected from the aircraft). The valve assembly includes a group of valves (e.g., umbrella valves) set into the path of the airstream. The valves may collectively modulate the flow rate of the airstream by adjusting their effective flow area.

An integrated vortex separator (IVS) is disclosed. The IVS includes a housing in communication with a waste inlet via which a waste stream is drawn under suction into a waste tank. In a first stage, the waste stream is drawn into a centrifugal vortex flow to facilitate the removal of solid and liquid waste from the waste stream, leaving a primary airstream. Within the housing, a filter assembly includes outer and inner inverted cones with a conical cavity therebetween, the cavity serving as a second stage into which the vortex flow is redirected to remove additional liquid from the airstream. Radial vanes extending inward from the outer cone define portals between adjacent vanes, through which the redirected vortex flow is isolated from the original vortex flow. Exhaust ports in communication with the conical cavity allow the substantially moisture-free airstream to be drawn from the IVS via a vent line.

An attachment and retaining mechanism is described for removably attaching a rotating filter element to a rotating shaft. The rotating filter element includes a filter media that is driven by a drive mechanism that rotates the rotating shaft. The filter element is removably attached to the rotating shaft such that the filter element and filtration system can be periodically replaced and/or serviced. In some arrangements, the drive shaft includes a D-shaped section that interacts with a mating section of the filter element sleeve of the rotating filter element. In other arrangements, the drive shaft includes at least one flat drive surface.

In a combustion engine, an exit stream of blow-by gases follows a fluid pathway through an oil and air separator and a breather filter, the oil and air separator including a first housing including a central chamber therein, the central chamber divided into a first outer portion and a second inner portion by a barrier; a filter material disposed between the first outer portion and the second inner portion; a cap directly coupled to the first housing, the cap including a first lumen therethrough, the first lumen including a first end disposed at the second inner portion; and a coupler removably coupling the cap and an extension portion including a second lumen therethrough.
