A releasable restraint for an evacuation system includes a plug body and a socket body. A ball, a plunger, a first spring member, and an adjustable fastener are disposed at least partially within the plug body. A spring force of the first spring member is adjustable in response to moving the adjustable fastener with respect to the plug body. The first spring member urges the plunger against the ball, and in response, the ball extends through a sidewall of the plug body and at least partially through a sidewall of the socket body to lock the plug body to the socket body. In response to a tensile force applied to the releasable restraint, the ball is configured to retract at least partially into the plug body, against the urging of the first spring member, to release the socket body from the plug body.

A joint for a swimming pool frame, and a swimming pool including the joint are provided. The joint includes a joint body including a leg pipe holder configured to have a leg pipe of the swimming pool frame inserted into the leg pipe holder. The joint also includes a side pipe holder configured to have a side pipe of the swimming pool frame inserted in the side pipe holder. A locking hole is formed through the side pipe holder. The joint body also includes a locking part including a locking pin configured to extend through the locking hole and through a corresponding connecting hole in the side pipe, thereby holding the side pipe to the side pipe holder.

A retaining system includes a lock including a drive portion that defines an axis of rotation, a radial direction, and a circumferential direction, and further includes a locking portion including an outer peripheral surface. A wing extends radially outwardly from the outer peripheral surface, while the locking portion is connected to the drive portion by a wall. A rib extends axially from the wall toward the drive portion forming an annular cavity, defining at least one detent receiving aperture that is disposed in the annular cavity.

An alignment device includes a first body and a second body, at least one retention member flexibly coupled to the first body, and a locking member coupled to the first body. The second body has an outer surface and an inner surface defining a cylindrical wall, the cylindrical wall defining a cylindrical opening, a first retention opening extending through the cylindrical wall and a second retention opening extending through the cylindrical wall. The first body translates within the cylindrical opening of the second body and the locking member engages with the first retention opening to position the alignment device in a first position and the locking member engages with the second retention opening to position the alignment device in a second position.

A positioning locking mechanism of a rotational member comprising a rotational positioning member provided with a positioning groove; a rotational member pivotally connected with the rotational positioning member and rotating around the rotational positioning member; a positioning member arranged in the rotational member and movably meshed with the positioning groove; and a locking operation member arranged in the rotational member to control the motion of the positioning member. The positioning locking mechanism can effectively ensure that the positioning and locking of the rotational member cannot be invalid due to accident collision or component fatigue.

An apparatus for processing pharmaceutical containers or components of pharmaceutical containers, and a securing device for detachably fastening a format part of an apparatus for processing pharmaceutical containers or components of pharmaceutical containers on a holding part of the apparatus. The format part has at least one container-specific, container-component-specific, or process-specific quality. The securing device includes a first securing element and a second securing element. The first securing element is arranged on or is part of the format part, and the second securing element is arranged on or is part of the holding part. The securing elements include magnetic elements that interact when the interconnected securing elements are in a securing position.

An attachment assembly includes a first component, a second component, and a locking device assembly. The locking device assembly is structured to move between an unlocked position corresponding to the second component being attachable to, and removable from, the first component and a locked position corresponding to the second component being securely coupled to the first component.

A positioning device for aligning and guiding a first half and a second half of a mold together. The positioning device may comprise a housing including identical wall members configured to define a cavity. Each of the wall members comprise a tab, the tab defining a recess and a protrusion on opposed sides of the tab such that the protrusion and recess defined by the tab of one of the wall member is configured to interlock with the recess or protrusion of the tab of an adjacent wall member to connect adjacent wall members. A first member may be slidably disposed within the cavity of the housing, the first member defining a void. The positioning device may further comprise a second member comprising a base and a protrusion, wherein the protrusion is configured to matingly engage the void of the first member.

A frame pool is disclosed including a frame assembly and a pool liner, the frame assembly including horizontal frame members and a vertical frame member coupled together via a T-shaped joint. The T-shaped joint may be constructed of plastic to facilitate attachment and detachment to the adjacent frame members and to resist galling and corrosion. The T-shaped joint may also be relatively small to improve the appearance and water containment of the frame pool.

A connection arrangement for tubular members may include a latch arrangement having a latch hook attached to a first tubular member and a striker arrangement attached to a second tubular member. The striker arrangement may include a transverse member extending transverse to the length of the second tubular member. The transverse member may be positioned proximate to the latch hook when an end of the first tubular member is positioned adjacent to an end of the second tubular member such that rotation of the latch hook engages the transverse member and effects a clamping force between the first tubular member and the second tubular member in a direction transverse to the rotational axis of the latch hook.
