A pipe device includes a pipe and a connection element. The pipe has a pipe jacket that has an inner surface and an outer surface and forms a flow channel. The connection element forms a through-channel that extends from a connection piece consisting of a first material (M1) and having a first opening to a second opening. The pipe jacket is positioned on the connection piece with a first pipe end consisting of a second material (M2). A bonded connection is formed between the first material (M1) and the second material (M2) in a contact region between the inner surface of the pipe jacket and a peripheral surface of the connection piece.

A method of bonding a thermoplastic component to a carpeted component and the carpeted component to cellulose-based core in a single pressing step is provided. The method includes providing a base component of a reinforced thermoplastic material, the thermoplastic component, a fibrous thermoplastic carpet or mat between the components, a sheet of thermoplastic adhesive and a core of cellulose-based material. The method also includes heating the thermoplastic component and the carpet at the interface between the thermoplastic component and the carpet for a period of time to soften the carpet. The method finally includes pressing the components, the sheet, the core and the softened carpet together under a pressure to cause the softened carpet to flow. The carpet at the interface is transformed into a solid bonding layer to bond the components together and the sheet bonds the base component and the core together to create a finished structure.

A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in spin weld engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

Examples of the present disclosure relate to a container for a three-dimensional printing system. The container has a chamber for storing a build material. The container has a base mounted within an open end of the chamber, the base having a channel structure and having at least one material-conveying structure. The chamber has an inner surface having helical raised portions to convey build material between the chamber and the at least one material-conveying structure during rotation. The at least one material-conveying structure has a radially aligned opening to receive build material conveyed by the helical raised portions in a direction perpendicular to an axis of rotation and is configured to transport the build material towards an opening of the channel structure.

A blind riveting apparatus (1) comprises a motor (3), and a clamp (31) for gripping the mandrel of a blind rivet, the clamp being movable substantially along the axis of the rivet. The apparatus further comprises a first transmission (51) configured to transfer rotary motion of the motor (3) to the clamp (31) when engaged; and a second transmission (52) configured to convert rotary motion of the motor (3) to linear motion of the clamp (31), and thereby retract the clamp (31) to pull on the mandrel, when engaged. A transmission control apparatus is arranged to selectively adjust the degree of engagement of at least one of the first (51) and second (52) transmissions, the transmission control apparatus comprising a variable-influence brake or clutch (58). Methods of blind riveting, and further pieces of blind riveting apparatus, are also disclosed.

A system (100), for manufacturing a rotor blade (112), comprises a first tooling (170), positioned at a factory location (114) and configured to assemble a first blade module (116), comprising a first-module skin (118) and a first-module spar (120), each comprising a first thermoplastic polymer (122) and a first reinforcement material (124). The system (100) comprises a second tooling (172), configured to assemble a second blade module (126), comprising a second-module skin (128) and a second-module spar (130), each comprising a second thermoplastic polymer (132) and a second reinforcement material (134). The system (100) comprises a first support (160), positioned at a field location (140) and configured to receive the first blade module (116), and a second support (162), positioned at the field location (140) and configured to receive the second blade module (126). The system (100) comprises a spar welding assembly (174), positioned at the field location (140) and configured to join the first-module spar (120) with the second-module spar (130), and a skin welding assembly (176), positioned at the field location (140) and configured to join the first-module skin (118) with the second-module skin (128).

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.

A maple sap line system and method for spin welding provides secure, unobstructed lines for collecting sap by creating a hermetically sealed connection between a lateral line and a mainline. A fitting connects the mainline to the lateral line. The fitting is spin welded to the mainline at a contact interface. The fitting comprises a protruding member that easily melts to create the frictional weld. The fitting has an elongated body comprising barbs that receive the lateral line. The fitting has a channel that enables fluid communication between the mainline and the lateral line. The flanges in the fitting register with a chuck to rotate the fitting against the main line at a high rpm. Molten debris formed in the channel is dislodged by drilling with a collared drill. The drilling provides fluid communication and creates a smooth inner surface in the mainline, and cuts off flanges from the fitting.

A wing leading edge assembly is disclosed including a leading edge panel and a cover panel located over the structural component. The cover panel has a thermoplastic layer with an inner surface. A thermoplastic fastening member extends through the structural component and is welded to the inner surface so that the structural component is fastened between the inner surface and the fastening member.

The present invention relates to a method for welding two polyamide plastics using a primer, the primer containing at least one polymer synthesized from at least one maleic anhydride or maleic anhydride derivative. The invention also relates to correspondingly welded products.
