The present disclosure relates to a screw-retaining device (1) comprising a connecting element (2) which in turn comprises a first end part (3), a second end part (4) and an intermediate part (5) that connects the end parts (3, 4). The first end part (3) comprises an at least mainly circumferentially running part (6) that at least partly encompasses a retaining aperture (7) that is arranged to engage the threads (9) of a screw (100), and the second end part (4) is attached to an object (8). The screw-retaining device (1) further comprises a washer part (20) with a first and second washer portion (21, 22), having a corresponding first and second washer aperture (23, 24). The washer portions (20, 22) are connected and spaced apart by a gap (26), and the washer apertures (23, 24) admit passage of a screw stem (19). The first end part (3) is arranged to be positioned in the gap (26) before a screw (100) that is intended to be retained is mounted to the screw-retaining device (1) via the retaining aperture (7) and the washer apertures (23, 24). The present disclosure also relates to a screw-retaining kit.

Spring rings and closed wire loops each can have two ends that are connected. The connected ends can be welded. The connected ends can be aligned for welding by incorporating complementary surfaces so that when joined, the tip at the first end mate to the tip at the second end. The mating can be self-aligning spatially and radially. The spring rings and the closed wire loops can be used in many applications, including in connector applications and seal applications.

An additively manufactured auxiliary device has a device body with a lower face, which is integrally connected to a component, and at least one mounting element, which projects from an upper face of the device body, wherein the at least one mounting element is arranged such that a contact face and at least one fastening element of the connection part can be attached to the device body such that the contact face of the connection part rests against the upper face of the device body in a planar manner, and such that each mounting element of the device body adjoins a fastening element of the connection part.

A universal locking pin can be inserted in a through hole for connecting a wide variety of objects. Once engaged in a through hole, the universal locking pin can function as mounting point for attaching items. Materials can be mounted to the attachment hole such as rope or carabiners, cords, rings, and other materials with suitable tensile strength. The locking pin can be scaled up or down in size and constructed from a variety of materials including metal, plastic, wood, ceramic, composites, and the like.

A device, system and method to connect a receiving member and a connecting device with a pin such that an asymmetrical configuration after the alignment of the connecting member and the receiving member does not give rise to asymmetrical glue distribution, nor asymmetrical shrinking nor curing drift. The receiving member has a receiving planar surface with at least one opening, and the connecting device has a main body with a contact plane, the main body having at least one opening where the connecting device is placed with the contact plane towards the receiving planar surface so that the at least one opening of the connecting device overlaps the at least one opening of the receiving surface, and the pin is inserted into the overlap. The system having a device for exerting a force between the contact plane of the connecting device and the receiving planar surface of the receiving member.

A vacuum adjustment device having a coupling for coupling an active element and a drive unit is disclosed. The drive unit adjusts the coupling from a normal position into an active position, in which the active element provides its intended effect. A separating device separates the process atmosphere region (P) from an outer atmosphere region (A), wherein the drive unit is at least partially associated with the outer atmosphere region (A). The coupling has a locking element cooperating with a collet which are arranged for a relative position variation axially along or parallel to a receiving axis that the locking element is adjustable relative to the collet into an open position and into a closed position. The coupling provides an open changing state in the open position by the interaction of the collet with the locking element and a closed working state in the closed position.
