In order to provide an anchor element for fastening an article to a further article, this anchor element being simple and inexpensive to produce and enabling an article to be fastened to a further article simply and reliably, it is proposed that the anchor element should include a base body that takes a hollow form, at least in certain regions, and surrounds a receiving space for receiving a fastening element, wherein the base body includes one or more elastically yielding spring elements that are formed by one or more wall portions of the base body, and these project into the receiving space in an installed condition of the anchor element.

Mobile data processing Systems (MSs) interact with systems in their vicinity, and with each other, in communications and interoperability. Information transmitted inbound to, transmitted outbound from, is in process at, or is application modified at a mobile data processing system triggers processing of actions in accordance with user configurations, for example to present content to a user.

An injection molding apparatus including: a valve pin driven by an actuator, the valve pin extending axially through at least a portion of the channel length of the fluid flow channel, the fluid flow channel including a throat, downstream flow of the injection fluid being restricted by a bulb portion of the pin, the valve pin having an intermediate position where downstream flow of injection fluid is unrestricted and a fully downstream position where downstream flow of injection fluid is stopped at both the gate and at the throat, wherein the actuator is driven by a valve assembly comprised of a spool mechanically driven by first and second actuators or solenoids that each separately engage the spool at opposing axial ends to effect movement of the spool back and forth between the drive fluid flow positions.

A self-drilling anchor assembly including a drill bit and an anchor positioned over and attached to the drill bit. In various embodiments, the drill bit includes a shank, a drill head integrally connected to one end of the shank, and a threaded tail integrally connected to an opposite end of the shank. The tail includes a mechanical engaging structure that is engageable by a tool to rotate the drill bit, and a helical thread formation to facilitate attachment of a securing device such as nut and washer to the tail of the drill bit. The anchor includes an elongated generally tubular body including an inner surface defining a longitudinally extending inner channel, and a head integrally connected to and extending from a first end of the body. The drill bit is configured to remain in the anchor and in the substrate after installation of the anchor assembly in the substrate.

Inexperienced users of conventional self-drilling drywall anchors may apply too much torque to its screw drive, even after the anchor has become fully bedded down in the drywall, under the mistaken impression that applying a greater torque will improve security of the anchor within the drywall. However, continuing to rotate the anchor after it has been fully inserted into the dry wall continues to rotate the anchor within the drywall and gouges out drywall material from around the anchor. Such gouging causes a cavity to form around the anchor, reducing its security within the wall. The present invention provides a self-drilling drywall anchor having a screw drive 16 that comprises a clutch configured to limit an amount of torque transmitted to the shank 5 by a tool engaged with the screw drive 16. In this way, a user may drive the anchor into a drywall, but over-tightening is prevented as the clutch limits the amount of torque transmitted to the shank 5, thereby preventing the external threads 7 on the shank from gouging out drywall material adjacent to the anchor and reducing the anchor's security within the drywall.

A plug system for repairing a hole in a wall includes a cylindrical plug body that has a grooving implement adapted to cut or abrade the wall at one end and a thread projecting outwardly from the plug body at an opposing end. A plug is adapted for fitting within a rear cavity and has at least one screw aperture. In use, with the plug body fixed with the rotary tool, the rotary tool is activated to rotate the plug body to cut or abrade the wall around the hole. The thread of the plug body engages the wall until the proximal end of the plug body is substantially flush with the wall to repair the wall, and to provide screw apertures at the desired location on the wall to hold an object with screws if needed.

An undercut anchor 2; 30, which facilitates the formation of a corresponding undercut in a blind hole for receiving the undercut anchor 2; 30, is formed to independently cut or form this undercut by rotating and spreading the undercut anchor 2; 30. Furthermore, a setting tool for forming this undercut at the bottom of the blind hole in the joining partner is proposed. Finally, a method of forming an undercut at the bottom of a blind hole using the setting tool is disclosed.

A reusable lifting apparatus includes a first mount assembly embedded within a first layer of a concrete sandwich panel and a second mount assembly embedded within a second layer of a concrete sandwich panel. The reusable lifting apparatus includes a lifting insert insertable within a void in one or more insulation layers between the first layer and the second layer. The reusable lifting apparatus includes a lifting bolt couplable to at least one of the first mount assembly, the second mount assembly, or the lifting insert through a hole in the first layer. The lifting insert is pivotable within the void about an axis through the lifting bolt. The lifting insert and the lifting bolt are removable from the concrete sandwich panel so as to eliminate thermal bridging between the first layer and the second layer via the lifting insert and the lifting bolt.

An internal cake support device for forming a multi-tiered cake. The device comprises a shaft having a first end and a second end and a head is provided at a first end. The device comprises a first measurement scale for measuring a linear dimension from the second end of the shaft. The device comprises a second measurement scale for measuring a linear dimension from the first end of the shaft.
