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 rock crusher liner movement detector is provided, wherein the detector is coupled to a crushing component and a liner such that the detector may detect a relative movement between the crushing component and the line.

Bowl liner movement detection method and apparatus

A bowl liner retaining device is provided that may allow for easy and quick replacement of worn or unusable bowl liners on cone crushers, while capable of providing a sufficient amount of tensioning load to hold the bowl liner in operational position during a rock-crushing operation.

Bowl liner retaining method and apparatus

A substantially unidirectional clutch for rock crushers that may help prevent undesired rotation of the cone.
