A panel joiner system includes 2 sets of suction cups couple together through a linear guide to allow the sets of suction cups to move toward each other for joining panels along the edges. A movement mechanism is also coupled to the suction cups to convert a rotational movement to a linear movement of the suction cups. A surface alignment module is coupled to the linear guide to move between the suction cups for aligning the top surface of the panels. Compressible materials or ball bearings can be disposed between the section cups and the linear guide to allow the panel joiner to adjust the panel positions for joining.

An integrated magnetic and mechanical device for anchoring structural elements of an assembly. The device comprises a first and a second junction element partially or totally made of ferromagnetic material, which can be connected to respective structural elements of the assembly, and at least one magnetic core having end anchoring faces each provided with at least one magnetic pole, in which the magnetic core extends along a longitudinal axis and anchors to bottom walls of the junction elements. The junction elements and the magnetic core are also configured themselves, or provided with mechanical interconnection members so as to increase, in combination with the magnetic anchorage, the resistance to external stresses and to prevent any relative movement between the junction elements in an assembled condition.

A fixation device for securing a linear element to a workpiece includes a contact component and a fixation component. The contact component typically includes (i) a first contact surface for application to a workpiece and (ii) a first opening for receiving a linear element. The fixation component typically secures a portion of the linear element on a side of the first contact component opposite the first contact surface. The fixation component engages the contact component to prevent passage of the linear element's secured portion through the workpiece when a tension is applied to the linear element in a direction opposite the contact surface.

A reusable closure system for providing easy closure and opening of an object such as a sheet forming a barrier. The reusable closure system generally includes a backing member adapted to be secured to an object, such as by an adhesive. A closure member may be connected to the backing member, with the closure member including a first portion which is removably connected to a second portion by one or more magnets. An optional outer closure member may be connected to the closure member, with the outer closure member including a zipper. Thus, the reusable closure system may be secured to various objects to allow for selective opening or closing of the objects in a versatile, user-selected manner.

A clarifier can comprise a floor, inner and outer walls that each extends upwardly from the floor such that a tank is at least partially defined by the inner wall and a launder channel is at least partially defined between the inner and outer walls and is disposed along at least a majority of a periphery of the tank. A launder cover comprising one or more flexible sheets can be disposed over at least a majority of the launder channel. Each of the sheet(s) can have opposing inner and outer edges, the inner edge coupled to the inner wall and the outer edge coupled to the outer wall, and can be configured such that, when a single one of the inner and outer edges is decoupled from the inner and outer walls, the sheet is deformable to at least partially uncover the launder channel.

A fastening device for fastening soft surfaced elements to each other comprises a planar top portion and two side portions. The side portions are coupled with the planar portion at one end via an angle portion, and are arranged essentially perpendicularly in relation to said planar top portion and essentially parallel with each other thereby forming a receiving opening for receiving said element between the side portions. In addition the side portions both comprise at least one tooth, which is inclined towards the opening and the element in use and thereby arranged to fasten, such as via friction or via penetration into the surface of the element, and thereby fasten the device to the element. Moreover at least one of the portions comprises a protrusion portion for receiving, focusing and attaching a magnetic member to the device so to allow the device to be fastened to an external member via said magnetic member.

A landscape edging installation includes ends of landscape edging joined together by a connector. The connector may have holes in lugs that are aligned with holes in the landscape edging tabs to receive a ground spike therethrough. The connector allows for and conceals a gap between the adjacent edging pieces. Thus, the arrangement allows for movement, such as contraction and expansion of the edging pieces along a length thereof. Such movement prevents damage to, or improper shifting of the landscape edging installation with respect to the surrounding environment due to large changes in temperature of the installation.
