Abstract: An inlet filter and method of use are disclosed. In one aspect, the inlet filter comprises a frame, filter material, a feed stream inlet, and a filtrate outlet. The frame is configured so an exterior of the frame is shaped like a wedge. In another aspect, the method comprises inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet. In a third aspect, a system comprises a plurality of inlet filters configured to be coupled together to filter a feed stream to a storm sewer inlet. The system can be configured so that the width of the plurality of filters is adjustable. For example, a first inlet filter and second inlet filter can be slidably engaged with a connecting filter.

Abstract: An inlet filter includes a frame, filter material, a feed stream inlet, and a filtrate outlet. The frame includes a thick portion and a narrow portion. The frame also includes a spring-comprising portion having an adjustable height. A method includes inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet. A system includes a plurality of inlet filters configured to be coupled together to filter a feed stream to a storm sewer inlet. The system can be configured so that the width and the height of the plurality of filters is adjustable. For example, a first inlet filter and second inlet filter can be slidably engaged with a connecting filter.

The frame is configured so an exterior of the frame is shaped like a wedge. The frame comprises a thick portion and a narrow portion opposite the thick portion. The thick portion of the frame comprises the feed stream inlet. The filter material is positioned along a bottom surface of the frame and a portion of an upper surface of the frame that is opposite the feed stream inlet in the narrow portion of the frame. In another aspect, the method comprises inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet.

Abstract: A battery having a flat top configuration is described including a handle attached across the centerline, the handle configured to be recessed relative to the periphery of the primary cover and to wrap around the terminals in a collapsed state, wherein the cover includes centerline battery cell vents and at least one side flame arrestor vent.

Abstract: A toolbox has a toolbox body with a tool storage compartment; a handle connected to the body; the handle having a light source, at least one battery, and a switch; the switch selectively energizing the light source by electrically connecting the battery and the light source. The light source may be first and second LEDs disposed on opposite sides of the handle's central grip area. The handle may be substantially longitudinally rigid and rotatably moveable relative to the storage compartment through an arc. The handle may be connected to the toolbox body by releasable mechanical connectors, such as by carabineers engaging opposing ends of the handle.
