A filter system for ambient air to remove airborne particulates in air that is to be used for engine operation. A filter media that is pervious to air and impervious to the particulates may be coupled to a filtered air chamber, which in turn may supply filtered air to the engine's air intake system. In various embodiments, the engine's air intake may be used utilized to draw air through the filter media into the filtered air chamber. An pressurized gas pulsing system may be used to periodically urge reverse airflow through the bag walls to maintain the permeability of the walls to the clean air.

Filter system for internal combustion engines operated in a contaminated atmosphere

A method and apparatus for wirelessly monitoring and/or controlling the processing operations of a mobile rock crushing plant.

Mobile rock crushing plant

An aggregate processing unit is provided that includes an in-feed conveyor adapted to have a first lower section that can move laterally to accommodate various processing configurations and to also allow for enhanced mobility.

Crusher in-feed conveyor method and apparatus

A rock crushing plant including rock crushers, screens and conveyors. The assembly is modularized whereby major components and associated support structures are organized into movable modules that are independently movable from site to site over public roadways. The modules are equipped with appropriate support wheels for traveling and stabilizing jacks for stabilization of the modules at a rock crushing site. Modifications are made to certain of the components to satisfy road height and width restrictions, e.g., folding conveyors. Each module is preferably equipped with its own power plant.
