Abstract: A self-cleaning conduit for a hydrocarbon fluid. The conduit includes a tube and a movable sleeve. The tube has an interior surface defining a flow passage for the hydrocarbon fluid. The movable sleeve is positioned within the flow passage to abut the interior surface and is movable along the interior surface in response to a change in an operating characteristic of the conduit to break-up deposits on the interior surface.

Abstract: A self-cleaning conduit for a hydrocarbon fluid. The conduit includes a tube and a mesh. The tube has an interior surface defining a flow passage for the hydrocarbon fluid. The mesh is positioned within the flow passage to abut the interior surface and movable along the interior surface to break-up deposits on the interior surface. The mesh is characterized by a mesh activation parameter (MAP) from one ten thousandths to six tenths.

Abstract: Embodiments relate to a system comprising a sensor module configured to detect and measure one or more air pollutants at a geographic location and generate air quality data, a cloud based application comprising a data processing module configured to receive, via a communication module, the air quality data and derive a first air quality index, a user device comprising an application program configured to receive, via the communication module, the first air quality index, the application program configured to suggest an alternate location having a second air quality index, and wherein the air quality data comprises one or more air quality parameters, the geographic location data corresponding to the one or more air quality parameters, and a time stamp; and wherein the system is configured to provide real-time air quality of the geographic location and the alternate location.

Abstract: A track guide assembly for a tracked vehicle, the track guide assembly having a base member adapted to support a track roller, and a shaft member releasably attached or attachable to the base member, the shaft member including a flange portion.
