A damping arrangement which is fastenable in an opening of a first component and by which a dampened connection of the first component with a second component is realizable, including, two identically constructed damping elements. Each damping element includes: a head portion with a first outer diameter, a shaft portion with a second outer diameter that is smaller than the first outer diameter and extends from a bottom side of the head portion, as well as a central first thru-opening, and only one sleeve with a central second thru-opening being arranged at least partly in the central first thru-opening of each damping element by means of a frictional and/or material connection. By means of the only one sleeve, the two identically constructed damping elements with bottom sides, facing each other, of the head portion with the first component arranged in between are fastenable to one another.

An arrangement configured to introduce a force from a fastening element into a plastic component, the arrangement including a force-limiting element that is embedded in the plastic component; wherein the fastening element is configured to fasten the plastic component at a body; wherein the fastening element is insertable through the force-limiting element, and wherein the plastic component includes a retention device which protrudes at least partially into an interior of the force-limiting element so that the fastening element that is inserted into the force-limiting element is retained in the force limiting element.

Disclosed are a bolt fastening structure which is couplable and releasable at one side and includes a fall prevention washer capable of preventing a bolt from falling, and an anti-vibration device including the same. By using an L-shaped bolt having a bent portion, even without assistance from below a substructure such as a grating plate, an operator above the substructure can install an anti-vibration device on equipment alone. In addition, by using a fall prevention washer coupled to an L-shaped bolt, a bolt can be prevented from falling below a substructure when working on the substructure.

A sealing bolt for sealing a container (e.g. for fissile materials), the sealing bolt adapted to cooperate, in use, with a locking device for locking a container lid to a container body of the container. The sealing bolt includes an upper part (i.e. adapted to be manipulated by an operator using a tool), a lower part (cooperating with the locking device 46) and an axial rod connecting the upper and lower parts, the upper part, lower part and axial rod being arranged coaxially about an axis. An integrity element is disposed in the upper part and a release arrangement (a detachable conical end-piece 24 retained by a ball 34 and recess 32 arrangement) is disposed so as to be releasably attached to the lower part. The sealing bolt is movable, through a first operator actuation of the upper part, from a first state, in which the integrity element is intact, to a second state, in which the integrity element of the sealing bolt is visibly broken. The sealing bolt is movable, through a second operator actuation of the upper part, from the second state to a third state, in which the release arrangement is released, thereby enabling disengagement of the locking device and removal of the lid from the container body. A locking system for a container, a method of releasably sealing a container, and a method of unsealing a container, are also disclosed.

Described is an anti-ligature enclosure for a wall-mounted apparatus. The enclosure includes a mounting box configured to be installed at least partially on a surface of a wall and at least partially within a space behind the wall. The mounting box includes a planar frame configured to be fastened to the surface of the wall and a recessed portion extending through the surface of the wall. The enclosure includes a mounting plate configured to contact and support the wall-mounted apparatus in an outward-facing position in the mounting box. The enclosure includes a cover plate configured to be securely fastened to at least part of an outer surface of the planar frame of the mounting box with one or more cover plate fasteners. The cover plate extends over and covers the wall-mounted apparatus and the mounting plate. An outer surface of the enclosure is flush-mounted to the surface of the wall.

A captive fastener is disclosed having a longitudinal slot along the shank for receiving a hold-out clip, and a chamber that houses a retractable cam member. The cam member is spring actuated to extend out of the shank and can be retracted into the cavity against the bias of the spring to pass through a primary panel and subpanel. The cam member is shaped to counter-rotate in the presence of a traverse force, such as the panel bearing against it.

An anti-rotation system includes a plurality of key components, each sized and shaped to fit within and form a rotationally keyed relationship with a corresponding internal drive recess of a threaded retainer covering an access port in a fluid end of a pump; and a single locking bar that spans between and couples to each of the plurality of key components after the key components are fit within the corresponding internal drive recesses.

A method includes fitting each of a plurality of key components into a corresponding internal drive recess of a plurality of threaded retainers covering access ports in a fluid end of a pump, coupling a single locking bar to each of the plurality of key components to form an anti-rotation system; and inhibiting rotation of the plurality of threaded retainers during operation of the pump using the anti-rotation system.

Captive fastener systems and structural assemblies having captive fastener systems are described. The captive fastener systems include a captive fastener assembly having a sleeve and a captive fastener arranged within the sleeve, a mounting assembly having a bushing and a mounting fastener arranged to pass through the bushing, and a joining body having a mounting aperture, wherein the sleeve is attached to the joining body and the bushing and the mounting fastener are configured to pass through the mounting aperture. The mounting assembly is configured to provide a first degree of movement of the captive fastener system and the captive fastener assembly is configured to provide a second degree of movement of the captive fastener system.

An accessory for tethering a cap for a SMA/SMP bulkhead to a device assembly without having to introduce elements that could compromise the integrity of the device assembly. The accessory includes a first portion that engages the SMA/SMP bulkhead and securely interconnects thereto, and a second portion that includes an opening where a tether chain is physically interconnected thereto. The tether chain includes the cap for the SMA/SMP bulkhead secured to the second end thereof.

A bolt configured for preventing loss of the bolt during removal can include a bolt head, a bolt shaft extending from the bolt head in an axial direction, the bolt shaft including threads, and a bolt capture channel defined through the bolt head and the bolt shaft in the axial direction. The bolt capture channel can include a head opening and shaft opening.
