A self-drilling anchor including a screw and an anchor body configured to receive a shank of the screw, the anchor body including: a flange at an end oriented toward a head of the screw, a threaded portion, a deformable expansion portion between the flange and the threaded portion, and a rotation locking mechanism preventing rotation of the anchor body relative to the wall. The threaded portion is configured to engage with the screw thread and advance in a direction of the flange, by deforming the expansion portion, when the screw is screwed into the threaded portion. The anchor body further includes a piercing element at the opposite end from the flange, the anchor including a fastening mechanism between the screw and the anchor body, the fastening mechanism being detachable by a torque, applied between the screw and the anchor body, equal to or greater than a predetermined torque.

A curved or straight document stand unit for supporting one or more documents is disclosed. The outside and inside surfaces of the document stand unit are vertically-oriented whereas both the top and bottom surfaces are planar. Further, the document stand unit disclosed herein has two longitudinal ends with vertically-oriented surfaces and a connection apparatus on at least one of the longitudinal ends. In the unit, the top planar surface and the bottom planar connect the outside surface and the inside surface. The top or bottom planar surface of the unit includes at least one slot or groove for insertion of a document.

A hollow wall anchor includes a wall penetrating component having an externally threaded portion and a wall penetrating end portion, and a body component having a wall face engaging portion and an internally threaded portion that receives the externally threaded portion of the wall penetrating component. Rotation of the components together in a first direction for wall penetration moves both the wall penetrating component and the body component into the wall until the wall face engaging portion of the body component engages the wall to limit further rotation of the body component while the wall penetrating component continues to rotate such that interacting threads of the two components pull the wall penetrating component further into the body component. As the wall penetrating component is pulled further into the body component one or more retention arms are expanded outwardly behind a rear surface of the wall.

An anchoring device for a attaching a plurality of substrates when only one side of the substrates is accessible.

A modular fluid control system comprised of a plurality of fluid control modules (11), each including a manifold portion (17), and a support element (14) to which the modules are mechanically fixed (12). The manifolds of adjacent units are pneumatically, but not mechanically, connected in order to communicate therebetween. In such an arrangement the modules can be removed from within an array without disturbing neighboring units.

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.

A storage chest has a base, a plurality of rails coupled to the base, and a side panel at each side coupled to the base between the rails. The base further includes a front panel coupled to the base between the side panel, a rear panel coupled to the base on a side opposite the front panel and between the side panels, and a cover movably coupled to the storage chest and configured to move from a closed position fully extending over the storage chest and substantially parallel to and opposite the base to an open position exposing an interior of the storage chest. The side, front, and rear panels and rails define openings providing access from an area exterior to the storage chest to the interior of the storage chest.
