A device comprising at least one pressure generation unit and a heating unit, the heating unit comprising a two-sided inductor and being configured to generate a uniform alternating magnetic field in an assembly comprising two parts made of composite materials comprising carbon fibers embedded in a resin and a field absorber. The field absorber is configured to absorb the magnetic field and comprising a ferromagnetic material. The field absorber is arranged at the contact walls of the two parts, so as to heat them to at least a transformation temperature of the resin.

A structural element that includes a central part formed of a fibrous material suspended in a thermoplastic matrix and at least one side part formed of a fibrous material suspended in a thermoplastic matrix and having at least one void therein. The central part and the at least one side part are bonded together while in a heated thermoplastic state to form a single, integral structure characterized by the absence of discontinuity across the bond plane of the structure.

A container is provided with a flange defining a container opening that may help expunge food product as the film and seal head comes down on the container flange. The flange of the container opening has a predetermined angle. The container flange with its sealing surface generally deflects or angularly pivots when sealed with the film during the sealing process. The container flange and film may push product contamination from the sealing surfaces inwardly into the container. The flange may be continuous about the periphery of the container opening.

A spin weld apparatus for spin welding a prepared end of a coaxial cable with a coaxial connector includes a cable clamp dimensioned to grip the coaxial cable and a drive collet dimensioned to enclose and rotationally interlock with a lateral surface of the coaxial connector. The drive collet is dimensioned to rotationally interlock with an interlocking portion of a spin welder. The spin welder is dimensioned to axially align the coaxial connector with the coaxial cable for spin welding when the drive collet is rotationally interlocked with the spin welder.

A method for setting up a joining apparatus for joining a light lens to a housing of a motor vehicle lighting arrangement. A first virtual model is created of the joining apparatus with a light lens and a housing received therein, a relative arrangement of the light lens to the housing corresponds to a target arrangement. A plurality of virtual models are created of the joining apparatus with the light lens and the housing received therein. The relative arrangement of the light lens to the housing deviates from the target arrangement in each case by means of virtual displacement of the adjuster. A target displacement is calculated of an adjuster on the basis of a functional relationship calculated and the relative arrangement in the test construction unit measured. A light lens is joined to a housing in the target arrangement by displacing the adjuster by the target displacement.

A sterile connection device includes first and second carriages. The first carriage defines a first portion of a proximal slot and a first portion of a distal slot, while the second carriage defines second portions of the proximal and distal slots. A controller executes a sterile connection procedure in which a solid cutting blade is heated, followed by the heated blade being moved to a cutting position to cut sealed proximal and distal tubes received by the slots. The second carriage moves proximally or distally with respect to the first carriage so as to align the cut ends of the tubes. The heated blade then moves out of the cutting position, followed by the first carriage moving toward the second carriage so as to press the cut ends of the tubes into contact with each other so as to sterilely connect the cut ends and define a joined tube.

A bracket presenter for an ultrasonic welder includes a one-piece first bracket portion and a one-piece second bracket portion mounted relative to one another. First and second tapered features are respectively provided by the first and second bracket portions and are nested relative to one another. The first and second tapered features engage in an extended position and are spaced from one another in a compressed position to provide a clearance enabling the first and second bracket portions to float lateral relative to one another. A spring biases the first and second bracket portions apart.

A vibration welding device includes a base plate, a vibrating body, and a plurality of position adjusting jigs. The vibrating body is capable of vibrating while holding an interior part which is an object to be welded. The base plate is disposed below the vibrating body. The base plate holds an instrument panel which is an object to be welded. The position adjusting jigs are connected to the vibrating body so as to be adjustable in position. The plurality of position adjusting jigs are disposed independently of each other.

A welding device with which two components can be pressed against each other comprises a static first section and a second section movable relative to the first section. At least one drive system is connected at a first end to the first section and at a second end to the second section, as well as at least one elastic guiding system by which the first section and the second section are connected to one another. The first section and the second section are movable relative to each other along only one axis due to at least one elastic guiding system, so that an axial length of the arrangement can be varied. A moving coil drive may be used or another drive without mechanical losses or with mechanical losses less than a clamping force to be applied during operation.

A device for welding thermoplastic tubes to a welding method, and to a welding knife. The device is provided for welding thermoplastic tubes, wherein the tubes are placed into tube holders and squeezed with the aid of tube clamps. A welding knife is moved between the first and the second tube holder and severs the tubes in the process. Cut ends and residual ends are thereby produced. The cut ends are aligned with one another by a relative movement of one tube holder with respect to the other tube holder and, by a horizontal movement of the two tube holders, are welded simultaneously to form continuous tubes.
