An add-on part (10) for connecting to a component (30). The add-on part (10) has a longitudinal axis (A) and a welding section (11) to be welded to the component (30) by torsional ultrasonic welding. The welding section (11) has a contact surface (12) for contact with a torsion sonotrode (70) and a welding surface (13) for connecting to the component (30). The welding section (11) is delimited, at least in some sections, by an inner vibration-decoupling zone (14). The inner vibration-decoupling zone (14) extends, at least in some sections, at an inclination to or parallel to the longitudinal axis (A). The method comprises a) bringing the welding surface (13) in contact with a welding region (31), b) applying a force to the contact surface (12) such that the welding surface (13) is pressed against the welding region (31), and c) introducing a torsional ultrasonic vibration into the welding section.

An applicator for and method of guiding a first web to a base web in a nonlinear pattern as the base web is advanced in a machine direction are disclosed. The applicator can include a support structure, a cantilever arm, a guide roller, and a connecting link. The cantilever arm can be supported by the support structure and moveable through a range of motion relative to the support structure in a cross machine direction. The guide roller can guide the first web onto the base web and can be pivotally mounted on the cantilever arm for pivotal movement of the guide roller with respect to the cantilever arm. The connecting link can be operatively coupled to the guide roller. Pivotal movement of the guide roller can be dependent on movement of the connecting link. Positioning of the guide roller in the cross machine direction can be dependent on movement of the cantilever arm.

A process for fabricating a three-dimensional, multi-layered fabric product with a moisture barrier is provided. A partially seamed inner lining fabric assembly having at least a two-dimensional shape is laminated with a membrane barrier film having flaps left un-laminated to cover at least one seam. The inner lining fabric assembly is further seamed and flaps of the of the membrane barrier film overlapped into contact with each other and sealed to provide a continuous moisture barrier. A process for fabricating a stretchable section of a garment with a moisture barrier is also provided. At least a section of a garment is formed from fibers arranged in a pattern having a direction of stretch in one direction and a three-dimensional surface texture such that a portion of the fibers protrude above another portion of the fibers. The stretchable section is stretched in the direction of stretch. Segments of a membrane barrier film are adhered to an outer edge of the protruding portion of the fibers while the section is stretched in the direction of stretch, leaving intermediate segments of the barrier film free from adherence to the section. In this way, the intermediate segments of the membrane barrier film include slack that folds up to form ruches when the section is in a relaxed state.

A satellite configuration includes a plurality of individual satellite buses each having a number of side panels that form a polygonal shape, where the individual satellite buses collectively fit together to form the satellite configuration having a regular polygon shape. A method of producing the satellite configuration includes forming a plurality of individual satellite buses each having a polygonal shape, and fitting the individual satellite buses together to form the satellite configuration in a regular polygonal shape.

An aerospace vessel including a fuselage, a means for causing the fuselage to fly coupled to the fuselage, and an environmental control system within the fuselage. The environmental control system includes a duct made of closed cell thermoplastic foam, such as polyvinylidene fluoride foam.

Parts (10) for connection to at least one further part (30, 30). The part (10) has at least two weld sections (11, 11) to be welded individually to at least one of the further parts (30, 30) by vibration welding. Each weld section (11, 11) has at least one weld surface (13, 13), for connection to the corresponding further part (30, 30), and is spatially separated from each other weld section (11, 11) by at least one vibration decoupling zone (14, 14, 23, 26). The part (10) has a particular arrangement of the weld section (11, 11) with respect to the center of gravity (S) or has a particular mass distribution with respect to the weld section (11, 11). Methods for connecting a part to at least one further part (30, 30) and a composite part (90) containing a part (10) and a further part (30, 30) are also disclosed.

Membrane elements that use multiple membrane leaves may have a limited total active membrane area due to an increased diameter at the ends of the element. Membrane leaves may comprise a permeate carrier positioned between one or more membrane sheets. Adhesive may be used to seal one or more edges of the membrane leaf. The membrane sheets, permeate carrier and the adhesive contribute to the thickness of the edges of the membrane leaf and the diameter at the ends of the element. A reduced thickness of the edges of the permeate carrier may reduce the diameter at the ends of an element. Another permeate carrier sheet may also be used that is distanced from at least one edge of the membrane sheet so the permeate carrier sheet does not contribute towards the increased diameter at the ends of the element.
