A method and apparatus for welding a thermoplastic structure. The apparatus comprises a base, a cover, and a channel. The base is formed of a material that is magnetically opaque to a frequency in a range of 30 KHz to 350 KHz. The cover is formed of the material. The channel extends between the base and the cover.

An opening device for a container includes a pouring spout defining a pouring opening to pour in use the content of the container, a closing element closing the pouring opening and connected to the pouring spout by breakable connector, and a closure fitted to the pouring spout in a removable manner to close the pouring opening at a region thereof different from that closed by the closing element; the closing element is formed in one piece with a protruding portion extending through the pouring opening and welded to the closure far away from the closing element.

A method for joining a first and a second component, at least one of which comprises a fiber-reinforced plastics material. The components are arranged in relation to one another in such a way that a gap region remains between the first and the second component. The gap region is filled, at least in portions, with an uncured plastics material filler in which nanoparticles are dispersed. Energy is introduced locally into the nanoparticles in order to cure the plastics material filler. In another aspect, the invention provides a device for joining two components.

A system for assembling a container and closure comprising an expanding collet which has a plurality of pivoting collet segments, each configured to simultaneously pivot radially outward about a pivot point and comprising. The collet comprises a lip that is engageable with the rim of the open end of the container and an angled tip positioned radially inward from the lip and shaped to press a countersink portion of the closure against an interior wall of the container as the collet segments pivot radially outward. As the container and the chuck are brought together, the rim engages with the lips of the collet segments and causes the angled tips of the collet segments to pivot outward toward the interior wall of the container, thereby pushing the countersink portion of the closure against the interior wall of the container.

An induction heat sealing device for providing a transversal sealing of a tube of packaging material, said induction heat sealing device including a main body including a first and a second sealing surface arranged to face the packaging material during a sealing state, a recess provided in the main body for receiving a knife during a cutting state, wherein the first and second sealing surface are placed on opposite sides of the recess, and an electric conductor arrangement, provided in the main body, for inducing eddy currents in the packaging material during the sealing state, wherein at least part of the first and second sealing surface are inclined and provided with a first and a second top section, respectively, such that particles in a product held inside the tube are pushed away from a sealing band of the tube as the sealing band is pressed toward the first and second top section.

A kit for fusing piping includes a plurality of couplings, each coupling having a susceptor layer concentric with a weld zone. A control unit provides a current to a wand with a handle for gripping by a user. The handle has opposing jaws mounted on the distal end, each jaw including an arcuate conductor such that the arcuate conductors form a circular inner diameter when the jaws make contact. A lever system couples to the distal end for opening and closing the jaws. The lever system includes a spring for selectively biasing the lever system in a latched position with jaws closed and an open position with the jaws open. Each coupling is sized such that the jaws will only close about the weld zone. The arcuate conductors create a fuse zone about the susceptor layer and the spring is outside the fuse zone.

A method for joining a fastener to a workpiece. The method comprising the following steps. Providing a fastening element including: a shaft-shaped anchor section which extends between a first end and a second end along an anchor axis; a flange formed on and extending radially to the first end of the anchor section, and the flange at least partially forms an application section, and; a joining material pre-applied to the application section and lying in an at least partially solid state, and wherein the joining material includes a first adhesive material and a second adhesive material. Providing a workpiece including a carrier surface. Arranging the fastening element on the carrier surface. Mixing the first and second adhesive materials by rotating the fastening element. And, joining the fastening element to the workpiece via the cross-linking reaction of the first and second adhesive materials.
