The present disclosure is directed to a method of assembly of a rotor blade for a wind turbine. The method includes placing a first rotor blade section onto a first set location of an assembly fixture, wherein the first rotor blade includes a first locating datum such that the assembly fixture at the first set location constrains movement of the first rotor blade section at the first locating datum along a first direction; placing the first rotor blade section onto a second set location of the assembly fixture, wherein the first rotor blade includes a second locating datum such that the assembly fixture at the second set location constrains movement of the first rotor blade section at the second locating datum along a second direction; and positioning a second rotor blade section onto the first rotor blade section within the assembly fixture.

Systems and methods for controlling and/or calibrating a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes calculating an amplitude and an offset for a drive signal based at least in part on previously calculated parameters and a negative pressure setting, generating the drive signal, and applying the drive signal to a pump system. The pump system can be fludicially connected to a wound dressing positioned over a wound.

Apparatuses for use in negative pressure wound therapy are described herein. In some embodiments, the apparatus includes a pump assembly having a pump housing, a magnet, an electrically conductive coil, and a diaphragm, wherein the electrically conductive coil is configured to move a portion of the diaphragm to pump a fluid through the pump apparatus, and a dampener positioned within the pump assembly configured to reduce sound generated by the pump assembly during operation of the pump assembly. In some embodiments, the apparatus includes a housing having a first section and a second section, and an illumination source disposed within the housing adjacent the first section, wherein the illumination source is configured to illuminate the first section, wherein the first section is one of transparent and translucent, and wherein the first section is thinner than the second section as measured perpendicularly from inside to outside the housing. In some embodiments, the pump apparatus includes components configured to be laser welded together.

A method for producing an induction connection sleeve includes laying up a first induction heating element in a first injection-mold half; laying up a second induction heating element in a second injection-mold half; mutually compressing the first and second injection-mold halves; injecting a thermoplastic plastics material into first and second molding cavities; opening the first and the second injection-mold halves; ejecting an internal part of a sleeve body having induction heating elements from one of the injection-mold halves; laying up the internal part of the sleeve body having the induction heating elements in a third injection-mold half; closing a third molding cavity; injecting a thermoplastic plastics material into the third molding cavity; opening the third molding cavity; and ejecting the finished induction connection sleeve.

A method for assembling a body and a cover of a vane by polymerisation of a resin. The covens positioned on a junction face of the body covered with this resin. A sheet is placed against a pressure side of the vane, formed by an outer face of the cover and an outer face of the body, so as to define a space sealed with a bead of mastic sealant. The bead of mastic sealant is deposited on the outer face of the body, around the junction face of this body. The space between the sheet and the pressure side of the vane is placed under vacuum during a heating operation of the vane in an autoclave, in order to press the cover against the body of the vane.

The present invention relates to method of manufacturing a wind turbine blade (10) the method comprising the steps of providing a first shell half (61) and a second shell half (62), providing a shear web (64) having a first edge (65) and an opposing second edge (66), and attaching the first edge (65) of the shear web (64) to an inner surface (67) of the first shell half (61). One or more guide members (70) are mounted onto an inner surface (68) of the second shell half (62) for guiding the shear web, each guide member comprising a hollow body (71) and a guiding surface (72).

The invention relates to a butt welding machine adjusting the ends of plastic pipes and welding them to each other, which comprises a cutter having a driving element for moving the trimmer by being driven, at least one movable claw, moving depending on a connector to hold pipes which are positioned, a motor which does not have direct connection with the cutter and transfers power to the cutter and to the movable claw via one connector for each, a cutter which needs to be had two different driving motion performed via two different connectors, a drive gear unit providing driving energy to the movable claw from one point.

The present invention provides a valve cup (10) for use with a container (30) for dispensing a fluid medium stored under pressure. The valve cup (10) supports a valve (50) and seals an opening (32) of the container (30) and is formed from a semi-crystalline polyester. The present invention also provides a container (30), wherein at least a part of the container (30) surrounding an opening (32) is formed from a semi-crystal-line polyester. A further valve cup (10) is formed from a metal or rigid material and further includes a polyester lining (70). Dispensing systems (1) including the above containers (30) and valve cups (10) are provided, wherein welding is facilitated between the container (30) and valve cups (10).
