A welding head comprises a welding element for welding a lid to an opening device of a container, a supporting body for supporting the welding element and a compensating device for compensating a possible mutual mispositioning of the welding element and the lid during welding of the lid to the opening device, the compensating device being interposed between the supporting body and the welding element, the compensating device comprising a planar spring arrangement provided with at least one planar spring element having a first member and a second member mutually connected by deformable elements.

A device for assembling plastic objects including caps for coupling to base support at least partially counter-shaped to the cap. The device includes at least part of an assembly line defining assembly path and assembly plane including the assembly path and plurality of spindles moveable along the assembly path by an apparatus and configured to controlledly pick up the caps, the spindles position and push the caps onto the base supports along the assembly path; positioning apparatus including first and second detectors, controller with auxiliary control system to translate and rotate spindles along directions perpendicular to assembly path and plane and third encoder to detect spindle orientation relative to assembly path. First detector to detect first orientation, second detector to detect second orientation and controller to detect first orientation and second orientation by detectors and operate auxiliary control system to align base support and cap.

A method includes a rotation locking step during which the rotation of the threaded hub about the central axis is blocked by heating a portion of the plug to soften, then by forcing the softened thermoplastic material to penetrate into, and then solidify in, a female cavity hollowed in the wall of the orifice to constitute a male member which fits into the female cavity. The female cavity forms, against the action of the male member, a guiding end stop preventing the male member, and therefore the hub, from rotating about the central axis to oppose any rotary screwing/unscrewing of the plug and maintaining a degree of freedom in axial translation along the central axis of the male member within the female cavity, so as not to impede a sliding of the hub and of its screw thread along the central axis against the wall.

Disclosed are example aspects of a method, process and machine to anchor objects to a surface using an encapsulated compound such as adhesive, expanding glue, hardening agent or other reactive and/or bonding substance intended for single use in a single anchor installation. A method of using an anchor with an encapsulated substance can comprise the steps of encapsulating a substance within an anchor and releasing the encapsulated substance through the insertion of a fastener into the anchor.

Child-resistant containers or packages having spinning collar cap assemblies are provided, as are methods for manufacturing such containers. In various embodiments, the child-resistant container includes a container body having an inner cavity, an opening to the inner cavity, and a container neck circumscribing the opening. A spinning collar is retained around the container neck and is rotatable relative thereto in at least a first rotational direction. The child-resistant container further includes an overcap, which is sized and shaped to enclose the opening when attached to the spinning collar. Through the provision of a suitable threaded interface the overcap can be (i) detached from the spinning collar by rotation of the overcap relative to the spinning collar in the first rotational direction and (ii) removably attached to the spinning collar by rotation of the overcap relative to the spinning collar in a second rotational direction opposite the first rotational direction.

A device for attaching a mouthpiece to an innerliner of an aircraft water tank is provided. A cylinder portion of an innerliner is thermally deformed to conform to an inner circumferential portion of a cylinder-like portion, and an inner circumferential portion of a dome portion of the innerliner is attached to a skirt portion by an adhesive. A lower mold includes two sections inserted inside the innerliner from the inner side of a mouthpiece in a folded state. The two sections are opened inside the innerliner and a holding member holds the two sections in an open state. The lower mold can be disposed in the innerliner sealed from the inner side of the mouthpiece, and abutment of an outer abutting surface of an upper mold against a first annular surface and abutment of an inner abutting surface of the lower mold against a second annular surface can be performed.

A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. Once the potting compound in at least a portion of the cavity has transitioned sufficiently to hold the filaments at a desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing. The invention can be applied to single fittings having multiple cavities and to multiple fittings having only one cavity per fitting.

When a cylinder portion of an innerliner is positioned inside a mouthpiece and when an upper mold and a lower mold are brought together, a projection portion is provided on an outer circumferential member of the lower mold that closes a gap between a section of an upper mold side positioning outer circumferential surface following on from an inner circumferential end of an outer abutting surface and a portion of the innerliner where an inner circumferential surface abuts. As a result, the portion of the innerliner that is thermally deformed is prevented from being displaced radially inward of the mouthpiece along a first annular surface.

A first structure made of a first polymer is joined to a second structure made of an incompatible second polymer by the steps of welding small bands of compatible tubing or material to the first structure to create raised structures or ribs, and mechanically linking the second structure with the ribs or raised structures at the desired attachment point. The mechanical linkage may be accomplished by using heat shrinking or mechanical compression (such as crimping) to force the incompatible second polymer around the ribs or raised structures or, in the case of raised structures formed as threads or nubs, by inter-engagement between the threads or nubs on the first structure and corresponding structures, such as internal threading, nub-receiving slots, or internal surfaces, of the second structure. The option of using the welded raised structures as threads or nubs for a threaded, bayonet, pin-and-slot, snap-fit, or similar connection enables the second structure to be removed from the first structure and replaced whenever the second structure becomes worn during use. The first structure may be an surgical laser fiber with an ETFE buffer layer, and the second structure is a protective structure may be made of PTFE, PET, FEP or PFA.

The present disclosure describes a three-dimensional object. The three-dimensional object includes a light polymerized body, at least one internal chamber residing within the light polymerized body, the at least one internal chamber having at least one frangible wall, and a curable component contained within the at least one internal chamber. The three-dimensional object may further include at least one channel extending inwardly from an outer surface of the light polymerized body toward the internal chamber and at least a portion of the at least one channel being adjacent to the at least one frangible wall of the at least one internal chamber. Methods of bonding an insertable object to a three-dimensional object and kits are also described.
