An earth-boring tool includes a formation-engaging structure with a formation-engaging surface at a distal end and a side surface between a proximal end and the distal end along a central axis of the formation-engaging structure. A generally linear recess may be formed in the side surface along an axis oriented at a non-parallel angle relative to the central axis of the formation-engaging structure. A generally helical recess may be formed in the side surface, and the generally helical recess may intersect the generally linear recess. Earth-boring tools may include such formation-engaging structures. Methods may be used to form such formation-engaging structures.

A method of stenting, comprises: implanting a stent assembly in a vessel of a subject, the stent assembly, including: a stent jacket, comprising an expansible mesh structure, formed of fibers of a diameter between about 7 micrometers and about 18 micrometers, the diameter having a property of forming a substantially stable layer of endothelial cells, covering the fibers, thus reducing platelet aggregation, and an expansible stent, operatively associated with the stent jacket. The method further comprises administering to the subject an active pharmaceutical ingredient (API) comprising a platelet aggregation reducer for a shortened time period, not exceeding six months, the shortened time period being a consequence of the property. In accordance with some embodiments, the administration of a platelet aggregation.

Fastening method, assembly and structure of engine oil fill extension tube can include an oil fill extension tube and a self-locking washer. The oil fill extension tube can include a plurality of locking edges disposed towards a first distal end of the oil fill extension tube, where the plurality of locking edges can define boundaries of a plurality of slots. The self-locking washer can include a plurality of teeth disposed on its top surface. The self-locking washer can be oriented over an opening in the oil pan, after which the oil fill extension tube can be threaded into the opening. The plurality of slots and plurality of teeth can be ratcheted together to fasten the oil fill extension tube into the oil pan when the oil fill extension tube is rotated clockwise. The washer can further include a locking extension to securely engage a portion of the oil pan.

The fork is cut into two pieces by abrasive waterjet. The toe-piece is formed with sidebars which, when the toe-piece is welded into the cover, greatly enhance rigidity of the cover-assembly. The heel-piece carries the load cells. In an option, a peninsula is cut in the heel-piece by waterjet, and the peninsula serves as the flexure-member of the loadcell.

A security attachment device can be used to securely attach a license plate to an automobile. A cap covers a screw used to attach a license plate to an automobile. An anchor anchors a container and the license plate to the automobile so that the container can freely rotate while anchored to the automobile. A ring is sized to fit over the container so that when the cap is attached to the container, the ring covers portions of the container not covered by the cap. The ring contains a first pin and the container contains a second pin hole. The first pin hole is located on the ring and the second pin hole is located on the container at locations that allow the first pin hole and the second pin hole to be aligned to receive a pin that when placed through the first pin hole into the second pin hole allows anchoring of the ring to the container when the cap is being screwed onto the container.
