Abstract: A filtration device may include a filter element and a housing that is configured to receive the filter element. The filter element may include a casing having a first outer surface and a flange connected to the first outer surface. The flange may include a plurality of snap members. A snap member, of the plurality of snap members, may include a fulcrum projecting from the flange and a lever mounted on the fulcrum. The housing may include a shell having a second outer surface and a plurality of ramp members. The plurality of ramp members may be fixedly connected to the second outer surface and may be configured to engage the plurality of snap members of the filter element. A ramp member, of the plurality of ramp members, may include an angled surface that extends from the second outer surface at an acute angle relative to the second outer surface.

Abstract: An articulated chain assembly includes standard links, a master link, and pins pivotably coupling together the standard links and master link. The master link includes a first half link and a second half link, and bolt holes extending through the first half link and the second half link. A first bolt is within a first one of the bolt holes and has a necked-down bolt shank defining a lesser necked-down axial length. A second bolt is within a second one of the bolt holes and includes a necked-down bolt shank defining a greater necked-down axial length. The first bolt and second bolt may have unequal full axial lengths.
