A welding assembly is disclosed. The welding assembly includes a plurality of separately controllable actuators (e.g., pneumatic, having an axially movable ram) to press a corresponding portion of a first workpiece (e.g., a discrete flange of a first stiffener) against a second workpiece (e.g., an outer skin) for welding operations (e.g., via induction welding).

An optical head for a laser transmission welding apparatus comprising a housing with an end on the outlet side with respect to a laser beam and a ball mounted in the housing. The ball may comprise a material whose refractive index is higher than the refractive index of quartz glass.

The invention relates to a system for positioning at least one spacer in a longitudinal pipe having an outer duct and an inner duct mounted in said outer duct, the system including a bracing module configured to maintain a pipe longitudinally along an axis while maintaining positioning clearance between the inner duct and the outer duct, and an insertion module having a pusher member, guided longitudinally along said axis, that is configured to move at least one spacer in the positioning clearance of the longitudinal pipe.

A holding structure (2) in an ultrasonic vibration welding device that welds workpieces by applying ultrasonic waves to the workpieces holds an ultrasonic vibration transmitter (horn) (5) bearing the transmission of longitudinally vibrating ultrasonic waves in holding members (8, 8). The horn comprises a horn body (51) having the length of one-half the wavelength of the ultra-sonic vibration. Holding structure (2) includes holders (7x, 7y) having a prescribed volume and thin sheet connectors (6a, 6b) placed at different positions (Pa, Pb) on the horn body (51). The horn body (51) is fixed to holding members (8, 8) by means of the respective holders (7x, 7y).

A converter having a converter base part, a bolt connected to the converter base part, a tensioning element and at least one piezo element with a through-opening, the bolt penetrating the through-opening and the tensioning element tensioning the at least one piezo element in the direction of the converter base part, wherein that the bolt is connected to the converter base part in a material bond.

The invention relates to a stamp-sealing unit comprising a punch designed as a sonotrode (8), and a die (5), said die (5) having an opening (15) and the punch being able to be moved in and out of the opening (15) in the stamping direction. The invention also relates to an ultrasonic processing device for stamping stamped parts out of a stamping material (2) and for sealing the stamped parts to unprocessed products (21).

A tank fitting apparatus and method is provided. The tank fitting apparatus includes a bottom plate apparatus. The bottom plate apparatus includes a bottom plate having a bottom surface, a top surface, and a bottom plate passageway. The bottom plate apparatus further includes a bolt connected to the bottom plate and extending from the top surface of the bottom plate. The tank fitting apparatus further includes a valve apparatus. The valve apparatus includes a pipe and a valve integrally formed with the pipe. The valve is movable between an open valve position and a closed valve position. A top plate integrally formed on the pipe and extends outwardly from the pipe. The valve apparatus has a connected tank fitting position where the bolt of the bottom plate apparatus extends through the top plate of the valve apparatus to connect the valve apparatus with the bottom plate apparatus.

A pressure jaw assembly (1) for a sealing jaw arrangement of a filling machine. The pressure jaw assembly (1) comprises a pressure jaw frame (10), a pressure element (20) arranged to be moved relative the pressure jaw frame (10), a compressing means (40) arranged at least partly between the pressure jaw frame (10) and the pressure element (20). The compressing means (40) is arranged to influence the relative movement between the pressure element (20) and the pressure jaw frame (10). The pressure jaw assembly (1) further comprises a guide (50, 52) for guiding the pressure element (20). The guide (50, 52) is connected to the pressure jaw frame (10), and the guide (50, 52) is arranged externally of the pressure element (20).
