Abstract: A filter cartridge for an air cleaner assembly is disclosed. The filter cartridge can include a media pack configured for installation into an air cleaner housing, the media pack extending along a longitudinal axis between opposite inlet and outlet flow ends, the media pack defining an outer perimeter. The filter cartridge can also include a circumferential shell surrounding at least a portion of the media pack outer perimeter. A radial flange extending from the circumferential shell proximate the media pack inlet end can also be provided. The flange can define a plurality of openings that are configured to receive protrusions on a housing body of the air cleaner assembly. The interaction between the protrusions and openings operates to ensure a secure seal between the housing body and the seal member.

Abstract: Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which a filter cartridge having a media pack and a seal arrangement surrounding the media pack can be installed. The air cleaner assembly may also include a projection-receiver arrangement in which the filter cartridge has at least one first member and the housing has at least one second member that interacts with the first member. In one example, a portion of the seal arrangement is coplanar with the first member and a portion that is below the first member such that the first member is located between the seal arrangement and an inlet end of the filter cartridge.

Abstract: A foldable lighting device includes a main panel and one or two side panels. A plurality of illuminants are provided on the main panel and the side panels. A pivot is provided to link the main panel with either side panel so that either side panel may be rotated with respect to the main panel to adjust the direction and brightness of illumination. As either side panel is rotated from the parallel position towards the main panel, the range of illumination becomes smaller and the light becomes more concentrated. As either side panel is rotated from the parallel position towards the back side of the main panel, the range of illumination becomes larger and the light becomes less concentrated.
