Abstract: A weld nut assembly, including: an annular flange structure; and an annular body structure coupled to the annular flange structure; wherein the annular flange structure and the annular body structure collectively define an inner bore, wherein at least a portion of the inner bore defined proximate the annular flange structure defines threads adapted to receive a screw disposed within the inner bore. The weld nut assembly further includes an annular washer or bottom structure coupled to the annular flange structure. Optionally, the weld nut assembly further includes an annular ring projection and a plurality of circumferential weld protrusions coupled to the annular flange structure. The annular flange structure is adapted to be welded to a surface of a body panel or other structure of a vehicle with the inner bore aligned with a hole formed through the body panel or other structure, the hole adapted to receive the screw therethrough.

Abstract: A lawn mower may include a blade housing configured to house a blade assembly, a powerhead configured to selectively operate the blade assembly responsive to application of power from one or more batteries, a battery receptacle operably coupled to the powerhead and configured to receive the one or more batteries, and a battery adapter configured to be operably coupled to the lawn mower and to a backpack battery to enable the powerhead to receive power from the backpack battery in addition to or as an alternative to one of the one or more batteries when the backpack battery is removed from a backpack harness and mated with the battery adapter.

Abstract: Arrangement (1) for decreasing galvanic corrosion between metal components that includes at least a first component (2) in which a first metal is a part, and at least a second component (3) in which a second metal is a part, whereby the first metal has a higher normal-electrode potential (e0) than the second metal. The first component (2) is intended, after mounting, to be in electrical contact with the second component (3). The first component (2) is coated with a substantially continuous surface layer (4) that is adjusted to give the second component (3) an insignificant galvanic corrosion velocity after mounting. The invention is preferably applied in association with attachment elements such as bolt or screw joint reinforcements, which include a more noble metal than the component or the components with which the attachment element should be in contact with after mounting, and is particularly, preferred for vehicle components.
