Abstract: An anchor bolt for use in a hole in a base material is provided and includes a stud, a sleeve disposed about the stud and a retainer nut, disposed in operable communication with the stud and having a dimension measured from a central axis of the hole that is at least as large as a corresponding dimension of the hole.

Abstract: The present invention discloses a self locking floating fastener. Further embodiments, forms, features, aspects, benefits, and advantages shall become apparent from the description and figures provided herewith.

Abstract: In one aspect, an anchor may include a threaded body, and a coaxial nut, wherein the anchor has a driving mode and an anchoring mode with the nut drawn rearwardly into the body by a threaded fastener to open the body radially outwardly. In another aspect, a one-piece self-drilling anchor includes a generally cylindrical threaded body with a pair of diametrically opposed inverted Y-shaped slits each having a generally axial slit and an inverted V-shaped pair of slits, a nut having splines for engage a threaded fastener, a pair of diametrically opposed inverted V-shaped wedges that are demarcated from the body by the V-shaped slits so that the body is relasably connected to the body, and a generally flat V-shaped drill tip.

Abstract: A device for connecting component parts includes a blind rivet nut adapted to be anchored in one component part by a riveter which has a threaded stud; a spacer which is in threaded engagement with the blind rivet nut and, by being screwed-out, reaches a position in which it is supported at the other component part; a connecting screw adapted to be screwed into the blind rivet nut; and a torque transmitting intermediate member, which is accommodated in a receptacle of the spacer and transmits a torque onto the spacer when the connecting screw is screwed in. For anchoring the blind rivet nut in the one component part, the threaded stud is capable of being inserted into the intermediate member and the spacer and then being screwed into the blind rivet nut without causing the spacer to be rotated in its screw-out direction.

Abstract: A rescue mission is initiated by deployment of an unmanned water surface vehicle some distance from a location at which an overboard person may be in distress. The water surface vehicle is self-propelled under signal responsive or remote manual control for directionally guided travel toward the distress location, at which a raft stored in the vehicle is ejected and inflated so as to floatingly support thereon the person to be rescued. The deployed raft is then moved from the vehicle for delivery to a rescue location.

Abstract: A mechanically adjustable wedge assembly including a cruciform-shaped driver and mating idlers applies force in multiple directions simultaneously thereby achieving the effect of several wedges in a single unit.

Abstract: The disclosure relates to an expansion pin consisting of a shank which at one end is provided with means for securing articles and at the other end is provided with a point. In order to obtain an anchoring having further expansion effect, the shank has an aperture in the form of a slot in which there is inserted a plastically and/or resiliently deformable insert which thickens the shank of the expansion pin in the region of the slot.
