Described is a heating device for thermally connecting a pipe, which has a first plastic material, to a bushing, which has a second plastic material, and which surrounds at least a section of the pipe, wherein an inductively heatable heating means is located between the pipe and the bushing and/or integrated in the pipe and/or the bushing. The heating device has a coil arrangement, which is excitable by a generator, and which has a first coil, which has at least one complete winding within a first cross-sectional area, and a second coil, which is electrically coupled to the first coil, and which has at least one complete winding within a second cross-sectional area. The first cross-sectional area is different from the second cross-sectional area. Furthermore, a heating system having such a heating device as well as a method for thermally connecting a pipe to a bushing are described.

A method of fastening a second object to a first object includes: providing the first object with an attachment surface; providing the second object; placing the second object relative to the first object, with a resin composition in between the attachment surface and the second object, wherein the resin composition has a resin having a first viscosity and being in a flowable state; pressing the first and second objects against each other and causing mechanical vibration to act on at least one of the objects until the resin composition experiences a vibration induced activation, which includes at least one of reduction of the viscosity of the resin compared to the first viscosity and activation of particles dispersed in the resin. The pressing and mechanical vibration are continued or repeated until the resin has at least partially cross-linked and the viscosity of the resin is increased compared to the first viscosity.

System includes a first object having an energy-assisted bonding (EAB) mechanism along a surface of the first object. The EAB mechanism includes a heat-activatable adhesive layer and a carbon-filled (CF) sheet material. The CF sheet material is electrically conductive for resistive heating. A control sub-system is configured to control a coupling actuator to drive an actuator body toward the first object, wherein the actuator body and the first object engage each other. The coupling actuator is configured to apply pressure to the EAB mechanism along the surface of the first object. The control sub-system is also configured to control the power source to apply a current through the CF sheet material of the EAB mechanism to provide thermal energy through resistive heating that activates the adhesive layer along the interface.

An applying unit for applying lids to necks of containers may be provided. The applying unit may include a conveying device configured to advance the containers along a path in an advancement direction; a group of applying heads, each applying head configured to screw a lid onto a corresponding neck; and a movement device configured to move the group of applying heads along the advancement direction, so that each applying head may be coupled to a corresponding neck along a portion of the path. The movement device may be configured to act on a common support element configured to support the applying heads of the group, so as to synchronously move the applying heads along the advancement direction.

A seam sealed heat resistant glove or mitt includes a front portion having a periphery and a rear portion having a periphery. The front and rear portions are joined to one another along a portion of their respective peripheries to define seams. The front and rear portions, when joined to one another, define an interior with seams formed at the interior and at an exterior of the glove or mitt with seams formed at the exterior. A welded thermoplastic material is disposed over the seams on at least one of the interior and the exterior of the glove or mitt and is cured by the application of ultrasonic energy. A method of making a seam sealed glove or mitt is disclosed.

Fluid flow conduits and apparatus and methods for joining the conduits, preferably in a sterile manner, are disclosed. Each conduit has a polymeric open end that is sealed by a sealing member that may include a heating element. The polymeric end material is melted, the sealing members are moved to expose the melted open ends of the conduits and the ends are brought together to form a fused or welded connection between the conduits.

Many garments made of denim material have factory created one or more discontinuities exposing a group of parallel threads and referred to as distressed denim. Sometimes, some or all of these threads become torn or rips or tears occur in the denim garment to create a discontinuity. A patch to cover the discontinuity is made of a plurality of side by side threads attached to one side of an adhesive panel and fabric material is attached to the other side of the adhesive panel. The threads, or entire patch, may be printed with indicia.

A porous body belt includes a body to be connected including a porous body, a connecting material A that bonds end portions of the body to be connected to each other, and a welding material A which is disposed between the body to be connected and the connecting material A, penetrates at least a part of a void portion of the porous body of the body to be connected, and adheres the body to be connected and the connecting material A to each other.

A porous body belt includes a body to be connected including a porous body, a connecting material A that is disposed on the body to be connected by spanning a gap between end portions of the body to be connected and contains a fiber A and a resin material A, and the resin material A penetrates at least a part of a void portion of the porous body of the body to be connected, and bonds the end portions of the body to be connected to each other.

An elongate hollow structure and method of constructing the hollow structure is described, whereby the hollow structure includes a radially inner portion and a radially outer portion adapted to be merged together to form a tubular wall structure. The method includes providing the radially inner portion, providing the radially outer portion about the radially inner portion, wherein a space exists between the radially inner and outer portions, the space containing a gas therein, and expanding the inner portion. The gas within the space between the inner and outer portions is arranged to be expelled as the inner portion is expanded.
