The present invention relates to a method of manufacturing a wind turbine blade (10). The method comprises arranging one or more shear webs (50, 55) within a first shell half. At least one support frame (80) is fixe to one or more anchoring points (86) on the inside surface (36b) of the first shell half, the support frame comprising a free end (81) for engaging with a lateral surface of the shear web. One or more guide element (74) are fastened to at least one of the lateral surfaces of the shear web such that the guide element extends laterally from the shear web to form a receiving space (88) between the guide element (74) and the shear web (55). The shear webs are then lowered into the first shell half such that the free end (81) of the support frame (80) is received in the receiving space (88) between the guide element (74) and the shear web (55).

A method for installing pipeline segments within a conduit. The method includes a step of securing a first pipe segment of the pipeline segments at a top end of the conduit, a step of aligning a main axis of a second pipe segment of the pipeline segments with the main axis of the pipeline, a step of lifting the second pipe segment from a first position associated with a bottom end of the conduit to a second position adjacent to the first pipe segment, a step of abutting a top rim of the second pipe segment against a bottom rim of the first pipe segment, and a step of attaching the top rim of the second pipe segment to the bottom rim of the first pipe segment.

A method of constructing an inflatable fluidic actuator. The method includes coupling a first interface to a tube configuration of membrane material at a first tube end by coupling the first interface to the tube configuration at the first tube end by generating at least one of: a first bond between the membrane material and one or more first sidewalls of the first interface and a first external face bond between membrane material at the first tube end onto a first external face of the first interface.

Systems for positioning and bonding a nutplate to a substrate having an aperture include a nutplate engagement fixture and a temperature sensor retention fixture. The nutplate engagement fixture includes a rigid tube and an elastomeric tube engaged with the rigid tube, the elastomeric tube having an elongated tube sized to provide a friction fit with the aperture and retain the elastomeric tube within the aperture. The rigid tube is operable to engage the nutplate at one end and the elastomeric tube is configured to anchor the nutplate engagement fixture at the aperture and secure the nutplate in contact with the substrate. The temperature sensor retention fixture includes a fixture body sized and configured to engage with the nutplate and at least one passageway within the fixture body sized and configured to allow a temperature sensor to be inserted or embedded therein with an end proximal a surface of the nutplate.

A method of constructing an inflatable fluidic actuator that includes generating a tube configuration with one or more shapes of fluid-impermeable membrane material, the tube configuration having a first tube end and a second tube end and an internal tube face and an external tube face. The method also includes coupling a first and second interface to the tube configuration at the first and second tube ends by respectively coupling each interface to the tube configuration at a respective tube end by generating at least one of: a first circumferential bond between the fluid-impermeable membrane material and one or more sidewalls of the interface; and an external face bond between fluid-impermeable membrane material at the tube end onto an external face of the interface.

An induction welding system includes a first gantry, a second gantry, and a support structure. The first gantry includes a first frame and a first plurality of trunks. The first plurality of trunks defines a first curved inner support surface of the first gantry. The first curved inner support surface has a first curvature geometry. The second gantry includes a second frame and a second plurality of trunks. The second plurality of trunks defines a second curved inner support surface of the second gantry. The second curved inner support surface has a second curvature geometry which is different than the first curvature geometry. The support structure includes at least one tooling member defining a curved outer support surface of the support structure. The support structure is longitudinally moveable relative to the first gantry and the second gantry.

Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs, preferably arranged into modules of more than two pocketed springs surrounding a central hole, are ultrasonically welded together when paired vibrating probes and anvils press layers of pocketed spring fabric from the rows of pocketed springs together and a welding pulse is transmitted to the vibrating probe.

A method and system for inserting a liner and lining pipes from inside a water main or other larger pipe. The method and system generally includes inserting a string inside the first pipe between a first end and a second end, inserting the string through a liner positioning tool, attaching a first end of the string to the liner, and then pulling the liner into the first pipe with the first string such that the liner extends from the first end to the second end of the pipe. One end of the string may be attached to the liner by a pulling insert, which may be a threaded insert that screws into an end of the liner, and which may further include a fluid passage to allow hot water or other fluid to flow through the insert while the string is connected to it.

A socket fusion jig includes a pipe saddle and coupling saddle spaced apart. Rotation of a handle causes the pipe saddle and coupling saddle to move laterally relative to one another so that the pipe held in the pipe saddle may be fused to the coupling held in the coupling saddle.

A welding device (10a; 10b) for welding an outlet element (12a; 12b) to a packaging material (14a; 14b) has at least one anvil (16a; 16b) comprising at least one receiving region (18a; 18b) for receiving the outlet element (12a; 12b) that is to be welded, has a holding element (20a; 20b) which the anvil (16a; 16b) is arranged on, and at least one welding die (22a; 22b), in particular a sonotrode, which is configured to interact with the anvil (16a; 16b) for a welding of the outlet element (12a; 12b) to the packaging material (14a; 14b), wherein the welding device (10a; 10b) comprises at least one support unit (24a; 24b) for supporting the anvil (16a; 16b), comprising at least one movably supported support element (26a; 26b), which is configured to exert a holding force onto the anvil (16a; 16b) in a welding operation state of the welding die (22a; 22b).
