A die for casting junctions of a coating of a pipeline is configured to be coupled to the pipeline to form an annular shaped closed compartment about a tubular joint portion comprising a tubular wall, which extends about a designated axis; a plurality of centering devices configured to align the axis of the tubular wall with a longitudinal axis of the pipeline; two annular walls arranged respectively at the opposite ends of the tubular wall; and two pluralities of vent openings arranged along the tubular wall respectively at each of the annular walls; and at least one feeding port configured to supply polymer material into the closed compartment.

A method useful for forming a composite part having regions in which fibers align with the principle stress vectors as well as regions having a randomized fiber alignment. To form the randomized fiber alignment, a preform cavity is formed in a preform arrangement, and the preform arrangement is molded in accordance with compression molding protocols to form a part.

A method and an apparatus for producing a reinforcement mesh. Here, a reinforcement fiber strand is firstly saturated with a resin (H) and cured to form a cured, fiber-reinforced strand material. The strand material present as an endless material is then cut lengthwise into bars, which are then used as longitudinal bars or transverse bars for forming the reinforcement mesh. A connecting material is used at each intersection point between a longitudinal bar and a transverse bar and is dispensed in liquid form at the intersection point or is liquefied and then cured at the intersection point. A fixed connection is thus created between the longitudinal bars and the transverse bars at the intersection points. Between the intersection points, the longitudinal bars and the transverse bars have portions that are free of connecting material.

A joint structure includes a first member having a fit-in groove, a second member made of a material different from a material of the first member and having an insertion section to be inserted into the fit-in groove, and a plurality of bonding layers having different hardness and formed between the fit-in groove and the insertion section.

Apparatuses and methods for on-line internal siliconing of glass bottles including a baking station for baking the siliconed bottles; wherein a siliconing station includes a support designed to selectively receive one bottle at a time, an injection device facing towards an inlet opening of the bottle, a mobile device for selectively blocking the injector against the inlet opening, a selective feeding device for feeding filtered compressed air and liquid silicone to the injector, the injector provided at the front, towards the support, with a drainage channel communicating with the inlet opening; an emitter to send towards a sensor and through the bottle on the support a beam of electromagnetic radiation; and a control unit to selectively inject into the bottle a mixture of silicone and compressed air and to process a signal emitted by the sensor to control the feeding device and/or a manipulator to discard defective bottles.

An overmolding method for forming joints in a fluid-flow apparatus utilizes a connector or fitting as a component for mold forming. The connector or fitting is not removed after the overmolding and thus forms part of the joint assembly.

Composite fasteners, associated blanks and also methods and apparatus for the installation of such fasteners are disclosed. An exemplary composite rivet disclosed comprises an elongated body including braided reinforcement fibers embedded inside the body and supported in a matrix material. Also disclosed are structural assemblies comprising composite fasteners and panels or other parts comprising composite and/or other materials.

A joint between at least one element of metal material and at least one element of plastic material is obtained by pressing these elements in contact against each other, with a simultaneous application of heat. A cladding of metal material and/or of plastic material is applied above the joint by additive manufacturing technology.

Devices, systems, and methods of improving paste flow during the manufacture of wind turbine blades are provided. When the first turbine blade half is aligned with the second turbine blade half, a gap is formed between the first shell and the bond cap. The assembly includes a first mold half corresponding to the first turbine blade half and a second mold half corresponding to the second turbine blade half. When the first mold is aligned with the second mold, a second gap is formed. A first barrier is disposed within the first gap and a second barrier disposed within the second gap thereby fluidly sealing a volume defined by the first gap and the second gap to direct adhesive paste flow along the blade span between the adjoining leading and trailing edges.

The present application relates to a thermally expandable composition which comprises at least one organic compound comprising at least two cyclic carbonate groups, at least one compound having at least one functional group with a pKa value of greater than 3 and at least one base, to shaped bodies which contain said composition, and to a method for sealing and filling voids in components, for strengthening or reinforcing components, in particular hollow components, and for bonding mobile components using shaped bodies of this type.
