A method of making a modular wind turbine blade is described. The modular blade comprises first and second blade modules connected together by a scarf joint between tapered spar caps of the respective blade modules. According to the method, first and second blade modules are laid up in the same mould assembly. A separating layer is arranged between the layups of the first and second module in a joint region of the mould. The separating layer has a thickness corresponding to a required bond thickness in the scarf joint when the modules are bonded together.

Provided is a laminate having a gel layer on a substrate able to protect the substrate during various types of processing used in industrial production steps prior to curing. The gel layer has excellent heat resistance, softness and flexibility, a low modulus of elasticity, low stress, excellent stress buffering properties, and electronic component retention properties. The gel layer has higher shape retention before curing but changing after curing into a hard layer having excellent release properties. The laminate is easily and readily releasable from the substrate even when the cured layer is localized. Applications thereof are also provided (such as an electronic component manufacturing method). The laminate comprises a laminated reaction-curable silicone gel and a sheet-like member laminated via an adhesive layer on top of the reaction-curable silicone gel.

A composite blade includes a composite blade body including reinforced fibers and resin; a metal layer provided on an outer side of a leading edge section including a leading edge that is a part of the composite blade body on an upstream side of an air stream, the metal layer having a thickness of equal to or larger than 5 micrometers and equal to or smaller than 100 micrometers; an adhesive layer provided between the composite blade body and the metal layer to bond the metal layer to the composite blade body; and an electric insulating layer provided in contact with a surface of the leading edge section of the composite blade body, the surface being on the side on which the metal layer is provided, the electric insulating layer having an electric insulating property.

The present invention provides a flexible mat with fluid conduit, methods of manufacture thereof and apparatus for the manufacture thereof. In an embodiment, the mat comprises a base layer, one or more fluid conduits and a thermoplastic bonding tape that attaches the fluid conduits to the base layer. The base layer can be a textile fabric, mesh or netting, or a flat flexible sheet. The base layer is preferably also formed of a thermoplastic layer. The fluid conduits can carry heated or cooled fluid, such as water, that can be used for heating or cooling an environment in which the device is deployed. For example, the device can be used for heating or cooling in a greenhouse environment. The fluid conduits can additionally or alternatively carry irrigation fluids, such as water or treated water, for irrigating plants and crops. The fluid conduits can additionally or alternatively carry gases, such as carbon dioxide (CO.sub.2) or carbon dioxide mixed with other gasses, for treating plants and crops.

Induction cooktops and operational methods are provided herein. A method of determining material composition of cookware on an induction cooktop can include determining that a piece of cookware is on the induction cooktop, inducing a current within the piece of cookware with an induction coil of the induction cooktop, and obtaining a peak induction coil current, a smoothed input line current, and a phase shift of current flowing in the induction coil. The method can further include comparing the peak induction coil current, the smoothed input line current, and the phase shift each to a set of predetermined ranges, and determining candidate material compositions for the cookware based on the comparing of each of the peak induction coil current, the smoothed input line current, and the phase shift.

An edge trim for pieces of furniture, including a meltable layer, is described. The molecular structure of the meltable layer contains both polar and non-polar parts. By way of a non-limiting example, an edge trim for pieces of furniture having an exposed edge of wooden or wood substitute material is described, comprising a molten layer and a structural layer, wherein the structural layer and the molten layer are connected in an adhesive bond, wherein the molten layer is made of a material that is chemically modified such that polar and non-polar components are found in a single molecular structure, wherein the molten layer contains energy absorbing additives, wherein the energy absorbing additives of the molten layer are selected from the group consisting of metal oxides, metal phosphates, metal salts of organic anions and combinations thereof.

A shear tie connector system for securing a frame component to a composite fuselage skin, which includes a shear tie connector and a fuselage mandrel, which defines a slot within which the shear tie connector is positioned.

A glued arrangement, preferably for a motor vehicle, is disclosed. The glued arrangement includes a first component, a second component, and at least one adhesive layer for connecting the two components. The adhesive layer includes a central zone and an edge zone that surrounds the central zone where, in the hardened state, the adhesive in the edge zone has a higher elasticity than the adhesive in the central zone.

A method of applying protective sheeting of polymer material to a pipeline, such as on a J-lay rig, includes the steps of driving a carriage along an annular path about the pipeline; extruding and simultaneously winding the protective sheeting about the pipeline via an end extrusion die fitted to the carriage; compressing the protective sheeting on the pipeline, directly downstream from the end extrusion die, so the protective sheeting adheres to the pipeline; and controlling the drive, extrusion, and compression steps so that the time lapse between expulsion of a cross section of protective sheeting from the end extrusion die and compression of the same cross section of protective sheeting is less than one second.
