A nut adapted to disengage with a threaded bolt, the nut comprising a base portion integrally formed to a top portion. The nut includes a bore positioned along a central axis through the base portion and the top portion, wherein the top portion is tapered between circumference of the base portion and the bore of the top portion. The tapering is at an angle between 0° to 45° relative to the diameter of the base portion; the base portion comprises at least two cavities, wherein the at least two cavities extend vertically into the base portion.

A booth module for exhibition includes: a frame; a main body dowel; a bolt detachably coupled to the main body dowel; and a cap dowel detachably coupled to the bolt, wherein the main body dowel has: a body having a bolt insertion hole formed therein; a button of which a part is inserted and installed in the body through a button installation hole formed in the body; and a spring installed inside the body and pushing one end of the button, and wherein the cap dowel has: a body having a bolt insertion hole formed therein; a button of which a part is inserted and installed in the body through a button installation hole formed in the body; and a spring installed inside the body and pushing one end of the button, wherein the buttons are provided with bolt through holes communicating with the bolt insertion holes.

A push-on fastener includes a base, a first radial barb, an axial support, a second radial barb, and a protrusion. The base defines an opening. The first radial barb extends from the base. The axial support extends from the base. The second radial barb extends from the axial support. The protrusion extends from the axial support.

A device for the hold-down and controlled release of space satellites installed on launchers and loads installed on space satellites, includes a blocking member made up of segments radially displaceable from a mutually approached retaining position to a mutually spaced-apart release position of a connecting screw. In order to control the radial displacement of the segments between the retaining position and the release position there are provided a rotatable element coaxial with the blocking member, an articulated mechanism which operatively connects the rotatable element with the segments of the blocking member, and linear motors for driving the controlled rotation of the rotatable element and, through the articulated mechanism, the simultaneous displacement of the segments of the blocking member.

An anchor assembly is disclosed for suspending objects to a concrete structure. The assembly includes an anchor housing having a jaw assembly therein and a opening for receiving an anchor member such as a threaded rod. The jaw assembly includes threaded rods having a threaded opening, a wood form anchor assembly and a metal decking anchor assembly. The wood form and the metal decking anchor assemblies may accommodate the anchor housing and the anchor housing is used in one of the wood form anchor assembly and the metal decking anchor assembly. The metal decking anchor assembly includes a nose-piece and the anchor housing is selectively connectable to the nose-piece via a locking connection such as a bayonet connection.

The present disclosure describes an anchor device for receiving and securing a shaft thereto. The device includes an outer housing within which a jaw assembly is secured. The outer housing of the device may in turn be secured to or within a support structure such as a building component. Jaw components of the jaw assembly may be threaded. Furthermore, the jaw assembly has at least two configurations. In a first configuration, at least one jaw component is positioned away from a central shaft axis against the biasing force of a biasing member. A removable or reconfigurable holding member or stop member selectively secures the at least one jaw component in its position. In as second configuration, the holding member is reconfigured by the inserted shaft to trigger movement of the at least one jaw component toward the central shaft axis and into contact with the shaft.

A selectively releasable separation nut for securing a payload and/or deployable equipment (hereafter “second body”) to a rocket, missile, or aircraft or spacecraft (hereafter “first body”) by way of a preloaded bolt, or other fastener, and releasing them on command. The separation nut may have magnetic eddy current damping components that dissipate as heat the strain energy stored in the separation nut, the bolt, and surrounding first body and second body structures during the bolt preload release. Energy not dissipated as heat during preload release may be stored as kinetic energy and dissipated as heat after the bolt mechanical release. The bolt acceleration and velocity are controlled throughout the release cycle. The bolt kinetic energy post release is less than 0.01% of the stored strain energy pre-release. Shock, impulse, and momentum transfer to the released second body are near zero.

A laundry appliance includes a basement housing comprising a capacitor receiver. A capacitor is disposed within the capacitor receiver to define a secured position. The capacitor receiver includes at least one retaining flange that is coupled to the basement housing via a living hinge. At least one retaining flange is outwardly biased away from a body of the capacitor when the capacitor is placed in an inserted position. At least one retaining flange includes a thread-engaging surface that operates to the secured position upon rotation of the capacitor in the inserted position.

A segmented nut has inner segments and an outer sleeve. Part of the sleeve interface portion and part of the segment interface portion engage when the sleeve rotates relative to the inner nut during release of the segmented nut with part of the segment interface portion at a greater distance from a central axis of the segmented nut than a minimum distance of the at least part of the sleeve interface portion from the central axis. One or more of the segments can include a retainer preventing the sleeve moving toward a free face of the segment(s). One or more of the segments can have a flange portion providing an increased working (compression) face relative to a plain segmented nut. An assembled segmented nut can include some radial freeplay for the segments to move radially whilst being retained within the sleeve prior to application of the segmented nut to a threaded bolt, stud or rod such that threading of the segmented nut onto the thread of the bolt, stud or rod removes the freeplay.
