An arrangement for fastening first and second components with automatic compensation in spacing between the components has a base element with first and second axial ends and a holding structure for holding the base element in an opening of the first component. An adjusting unit screwable into the base element has a driver unit. A fastening screw is connectable to the adjusting unit via the driver unit, such that, when the fastening screw is rotated, the adjusting unit can be rotated conjointly and moved into contact with the second component. The holding structure has a holding segment arranged such that, by the holding segment, an angle between the first and second component can be compensated such that, when the adjusting unit makes contact with the second component, a longitudinal axis of the fastening arrangement runs perpendicular to a plane of the second component.

A kit includes an adjustable chock provided with a first component having screw threads and with a second component having screw threads cooperating with the screw threads of the first component and having a lower bearing surface, and with a bearing element provided with a lower bearing surface in contact with an upper bearing surface of the first component, and with an upper bearing surface. The kit further includes at least one friction ring adapted to be mounted against the lower bearing surface of the second component or against the upper bearing surface of the bearing element.

An eccentric bushing assembly comprises an outer eccentric bushing configured to be disposed in an opening of a panel comprising a central axis. The outer eccentric bushing is operable to float axially, rotate circumferentially, and to move radially with respect to the central axis. The eccentric bushing assembly further comprises an inner eccentric bushing disposed radially inward from the outer eccentric bushing and interfacing with the outer eccentric bushing, the inner eccentric bushing is operable to rotate relative to the outer eccentric bushing. The eccentric bushing assembly further comprises a spherical bushing comprising a through hole operable to receive a connecting pin therein and to rotate in at least one degree of freedom. The rotation of the spherical bushing can facilitate alignment of an axis of the pin with the through hole.

A structural assembly using at least one anchor assembly for attaching a first structure to a second structure is described. The anchor assembly has a body having a first face and a second face. The first face is transverse to the second face and has an elongate slot. The second face has a through hole. The body is fabricated from a material that fails at a temperature in excess of 1,000° F. A fastening member is positioned in the elongate slot for connecting the first face to the first structure and for sliding engagement with the elongate slot in response to relative movement of the first structure and the second structure.

The present application is directed to a curvature adjustable magnetic strut for securing pipe, conduit and tubing to a curved structure for storing liquids and gasses, such as a fuel tank. More particularly, several variants of the curvature adjustable magnetic strut is disclosed which enables varying curved or flat surfaces to be accommodated in securing pipe, conduit and tubing to a cylindrical tank, whether that tank be in the vertical or the horizontal position. The curvature adjustable magnetic strut comprises a strut affixed to a base plate having three or more magnets attached. In operation, the base plate can be curvature adjusted using one or more adjustment screws. In related embodiments, varying length struts with varying length single and double hinged bracket assemblies thereon are secured to both securing strut plates and magnet base plates having two or more magnets are used to adjust for varying tank curvature.

A system and apparatus are disclosed including PV modules having a frame allowing quick and easy assembling of the PV modules into a PV array in a sturdy and durable manner. In examples of the present technology, the PV modules may have a grooved frame where the groove is provided at an angle with respect to a planar surface of the modules. Various couplings may engage within the groove to assemble the PV modules into the PV array with a pivot-fit connection. Further examples of the present technology operate with PV modules having frames without grooves, or with PV modules where the frame is omitted altogether.

The present invention relates to side tensioning assemblies for retaining screen media to the side plates of a vibrating-type screening machine. The side tensioning assembly includes a tensioning rail and at least one angle box mountable to a side plate. At least one bolt assembly provided for fastening the tensioning rail to the side plate and to angle box. Bolt assembly is provided with is a shoulder bolt that is secured to a terminal end of the bolt. The angle box includes an aperture sized to allow the bolt assembly passage therethrough, and a movable plate with a cutout. The cutout is sized larger than the bolt but smaller than a nut. The movable plate has a bolt-securing position and a bolt-releasing position to allow access to the aperture in the angle box such that the bolt assembly can be detached from the angle box without being disassembled.

An adjustable bracket assembly for securing an edge of a panel relative to a surface. The adjustable bracket assembly includes a mounting member and a bracket member. The mounting member has a body configured for mounting on the surface and defining at least two fastening screw receiving holes. The bracket member includes an extension arm extending perpendicularly to a mounting arm. The extension arm includes a panel clamp and the mounting arm includes a mounting plate extending therefrom. The mounting plate defines at least two fastening screw holes and at least two adjustment screw holes therethrough. A fastening screw extends through each fastening screw hole and is received in a respective fastening screw receiving hole. An adjustment screw is positioned in each adjustment screw hole and is threadably adjustable to contact the mounting member body and adjust the angular relationship between the bracket member and the mounting member.

A connection unit for connecting a first component to a second component with a distance in between. The connection unit has a connection screw having a head in the shape of a first ball segment and a shank. The shank has an outer thread. The connection unit also has a base element having: a second outer thread, and a first portion having a first inner diameter; a through-opening is provided at a second axial end and has a second inner diameter which is smaller than the first inner diameter, and an outer side of the base element is in the shape of a second ball segment. The first portion and the through-opening are distanced axially and are connected by a transition portion, which at least partly provides a bearing surface for the head of the connection screw, and the shank extends through the through-opening.
