The invention relates to a device (100), a system (10) and a method for modifying the cross section of a tower section (1) of a wind turbine, wherein the tower section comprises a flange (4) located at an end (3) of the tower section having a plurality of through holes (5) spaced around its circumference for securing said tower section to another wind turbine section. The method comprises securing tensioning mechanism (14) to each of a pair of said plurality of through holes in the flange of the tower section, said pair of holes being generally opposed; and applying a tensile force between said pair of holes in the flange of the tower section.

An anchorless-installed wall-mount bracket system comprising a plurality of wall-penetrating fasteners. A wall-mount portion constructed to orient the wall-penetrating fasteners for supporting a load. A load bearing portion constructed to support the load at a hanging distance from the wall-mount portion. The load bearing portion extending laterally away from the wall-mount portion. Afinial attachment feature constructed to support any one of a plurality of distinct finials adapted for use with the wall-mount bracket system. The finial attachment feature disposed on the load bearing portion so that a finial attached thereto is at least partially exposed beyond the load when the load is disposed at the hanging distance.

In order to alleviate a mismatch problem of thermal deformation, in all directions, of a connecting and installing structure between a CMC turbine outer annular component and a metal intermediate casing, a connector and an anti thermal mismatch connecting device are provided. The rod part of the connector comprises a subtractive hollow section and a cylindrical section. The subtractive hollow section is composed of a central shaft, a plurality of supporting rib plates extending outwards from a peripheral surface of the central shaft and inclined radially relative to the central shaft, and a plurality of outer annular plates arranged around the central shaft, with a circumferential gap between adjacent outer annular plates. The supporting rib plate is connected with the central shaft and the outer annular plate, and the central shaft is connected with the cylindrical section. The anti thermal mismatch connecting device the connector.

A unitary steel bracket has an arced portion and a hanger appendage extending perpendicularly from a convex perimeter of the arced portion. The arced portion has two opposed planar surfaces with parallel mount holes through each end. The hanger appendage has two opposed planar surfaces coplanar with the arced portion planar surfaces. A portion of the hanger appendage is bent at a 90-degree angle and has a support mount hole perpendicular to the parallel mount holes. the bracket is prefabricated to a predetermined bracket size corresponding to a predetermined pipe flange size. A method of hanging joined flanged includes providing the bracket; aligning the parallel mount holes with holes on a pipe flange; inserting connection bolts through the holes; threading nuts onto the bolts to a predetermined torque; and attaching the support mount hole to a building structure.

A nut cap assembly for securing an internal component to an external component includes a seal cap having a base and a shroud extending from the base. The base includes a mounting flange configured to be mounted to the internal component. The base includes an opening at a mounting end of the base configured to be mounted to the internal component. The base includes a seal groove surrounding the opening configured to receive a seal. The seal groove is open at the mounting end to interface the seal with the internal component. The shroud includes a nut pocket has a cap anti-rotation feature. The nut cap assembly includes a nut received in the nut pocket. The nut includes a threaded bore configured to threadably receive a threaded fastener used to secure the internal component to the external component. The nut includes a nut anti-rotation feature interfacing with the cap anti-rotation feature.

A support for attachment to a structural member comprising, the support comprising a pair of side members; a receiving portion located in each of the pair of side members configured to receive a portion of the structural member; and an end member, wherein the end member includes a connection portion configured to facilitate connection of the end member to an adjacent support, and wherein at least one of the pair of side members comprises a connection portion configured to facilitate connection of a utility object thereto.

A centering screw for aligning two elements, particularly a workpiece and a carrier, relative to each other, the centering screw having a first end section with a first outside diameter and a first length, and a second end section with a second outside diameter and a second length, the first end section having a first thread, at least in sections, and a cone being provided for the centering. In this case, the centering screw has the cone in an intermediate section between the first end section and the second end section, the cone having a diameter changing along the intermediate section, the diameter at an end of the cone facing away from the first end section being larger than the first outside diameter, and the end of the cone facing away from the first end section being assigned an axial stop facing away from the first end section.

A joint includes: a first coupling section configured to be coupled to an end of a first pipe; and a second coupling section configured to be coupled to an end of a second pipe. The first coupling section has: a first sealing portion configured to be continuous with a first sealing surface or a second sealing surface of the first pipe; and a first non-sealing portion configured to be continuous with a first non-sealing surface or a second non-sealing surface of the first pipe. The second coupling section has: a second sealing portion configured to be continuous with a first sealing surface or a second sealing surface of the second pipe; and a second non-sealing portion configured to be continuous with a first non-sealing surface or a second non-sealing surface of the second pipe.
