A method of cutting a wafer of composite core from a bulk composite core including the steps of placing the bulk composite core in a container, the bulk composite core having a plurality of tube members; depositing a potting compound in contact with an outer surface of the bulk composite core; curing the potting compound; and after curing of the potting compound, cutting through each of the tube members. A method of cutting a wafer of composite core from a bulk composite core, the method comprising the steps of stabilizing the bulk composite core by wrapping an exterior of the bulk composite core with a composite wrap, the bulk composite core having a plurality of tube members; curing the composite wrap; and cutting through each of the tube members.

A method of making a wind turbine blade is described. The blade comprises first (12) and second (14) half shells bonded together and a shear web (16) bonded inside the shells. Prior to joining the shells together, the shear web is positioned in one of the shells. A plurality of bars (70) are attached to the shear web and engaged with a plurality of mounts (80) in order to support and stabilise the shear web relative to that shell. The shells are then arranged one above the other whilst the bars remain attached to the shear web. The bars continue to support the shear web whilst the shear web is aligned with the other shell. The bars are then detached from the shear web and the shells are brought together to bond the shells to each other and to bond the shear web between the shells.

Tapping assembly for a beverage, including container including a first and second container, wherein the first container has a neck portion and the second container is suspended in the first container, from the neck portion thereof. A neck region of the container is provided with at least one opening in a side wall thereof, preferably in a neck region of the first container, opening into a space between the first and second containers. The assembly further includes a connecting device, connected or connectable to the neck portion, wherein the connecting device includes at least one connecting element for connecting to the at least one opening, wherein the connecting element is connected to a source of pressurised gas.

The present disclosure is directed to methods for joining rotor blade components using thermoplastic welding. The method includes arranging a first thermoplastic component and a second thermoplastic component together at an interface, determining a size of a tolerance gap between the first and second components at the interface, placing a thermoplastic insert between the first and second components at the interface, the insert being larger than the tolerance gap, heating the insert and the first and second components such that the insert begins to flow so as to fill the tolerance gap between the first and second components, applying pressure to the interface such that the insert and the first and second blade components remain substantially in direct contact with each other at the interface, and welding the insert and the first and second components together at the interface, wherein the heat and the applied pressure between the insert and the first and second components at the interface maintain the insert and the first and second substantially in direct contact at the interface during welding.

A sensor module contains a sensor unit, a sensor cover, and a main body. The sensor unit has a sensor surface and a base surface. The sensor cover covers the sensor surface and at least a section of the base surface. The sensor cover is connected to the base surface and/or the main body by a fused connection. The main body is connected at least to the base surface of the sensor unit by a fused connection with a selectable relative position in relation to the sensor cover. Pre-mounting of the sensor unit in a sensor cover and advantageous encapsulation of a sensor can thus be achieved.

The invention relates to a method of manufacturing a shell part (101) for a wind turbine blade also comprising an add-on component (301, 302) connected to the shell part (101) along a connection face. The method comprises the steps of providing an insert (102) with a side surface of approximately the same shape as the connection face, positioning the insert in an open mould, and placing one or more layers (105) of material in the mould (103) to form the shell part (101) wherein the layers (105) are placed in abutment to the side surface (104) of the insert (102) thereby forming a side surface (108) of the shell part (101) of approximately the same shape as the connection face. After resin cure, the insert (102) is removed. The invention further relates to a method of manufacturing a wind turbine blade shell member (100) comprising such a shell part (101), and layers (105) of material are placed in the mould (103) in abutment to the side surface (108) of the shell part (101) to form the add-on component (301, 302).

Joints for joining panels together, such as for joining honeycomb sandwich panels used in aerospace applications, and methods of joining said panels are disclosed. In some examples of disclosed joints, a first panel and a second panel can be joined together to form a joint. The first panel can be a flat panel that includes a rabbet formed along a first longitudinal edge, and the second panel can be a curved panel that includes a notch formed along a second longitudinal edge. In forming the joint, a portion of the rabbet can be positioned within the notch, and the flat panel and curved panel can be oriented at a non-parallel and non-perpendicular angle to one another. Adhesive can be applied along the rabbet and/or the notch in order to secure the joint.

A method of making an aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The method has the steps of sealing the valve to the product delivery device and outer container at respective annular welds or other bonds joining the valve to the product delivery and to the outer container. The welds, or other bonds may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes. Suitable welds include spin welds.

A silencer for reducing gas noise in a combustion engine intake system has a tubular casing with a first casing part and a second casing part connected to each other by a weld seam to form an outer casing wall, wherein the weld seam is a part of the outer casing wall. A third part for compensating gas noise is positioned inside the tubular casing. The third part is arranged in the tubular casing such that an annular cavity is formed by the third part and the outer casing wall. A weld flash protrudes from an inner surface of the outer casing wall into the annular cavity and is contained therein. The silencer is produced in a single welding process in which the first and second casing parts are connected to each other to form the outer casing wall and the third part is connected to the tubular casing.
