A manufacturing method of a composite structure includes: (a) preparing: a metallic sheet(s) having a through-hole(s) penetrating throughout the metallic sheet(s) in its thickness direction; (b) setting a prepreg(s), constituting a fiber reinforced plastic sheet(s), and the metallic sheet in a pair of dies, which have a recess(es) arranged at a position(s) opposed to one side opening(s) of the through-hole(s), the recess(es) having a larger diameter than the one side opening; (c) closing the dies, wherein, upon closing, (ca) the prepreg(s) and the metallic sheet are molded to the predetermined shape, while surface-contacting therebetween, (cb) at least one of the prepreg(s) and a patch member(s) is extruded into the through-hole(s), so that the shaft part is molded, and (cc) the patch member(s) forms at least part of a head part(s) in the recess(es), the head part(s) integrated with the shaft part(s) and engaging on the metallic sheet(s).

The process for the manufacture of windows/doors (1), characterized by the fact that it comprises the following steps: providing at least one inner panel (2) for windows/doors; providing a plurality of plastic profiled elements (3) for windows/doors, each of the profiled elements (3) comprising at least two areas to seal (5), coupleable to the areas to seal (5) of the other profiled elements (3), and at least one longitudinal slot (6), in which a respective perimeter side (4) of the inner panel (2) is insertable; performing a step of mechanical machining by chip removal on at least one of the areas to seal (5); heating the areas to seal (5); coupling the heated areas to seal (5) to one another by pressing the profiled elements (3) one against the other to maintain the areas to seal (5) in mutual contact and define the frame for windows/doors, the coupling taking place with the inner panel (2) inserted in the longitudinal slots (6) to define a window/door (1) which is composed by the frame and by the inner panel (2) contained in the frame.

The first electrode section (7a) and the second electrode section (7b) are formed such that the outer portion connected to the upper portion of the heating section (6) is thinner than the inner portion connected to the lower portion of the heating section (6). The heating section (6) and the first electrode section (7a) are interconnected by an R-shaped first connecting portion (21). The inner circumferential sloping surface of the heating section (6) and the second electrode section (7b) are interconnected by an R-shaped second connecting portion (22). The first and second connecting portions (21)(22) are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion (6b) is smaller than the thicknesses of the first and second connecting portions (21)(22).

A high altitude balloon, including a method and machine for manufacture, uses a perimeter border strip to couple two circular balloon panels with a lap or butt seal. Simultaneous sealing of two perimeter seals, one between the border strip and each of two balloon panels, is provided by supporting stacked balloon panels on a rotatable support and sealing around the full perimeter of the two interposed balloon panels and the border strip. The method and machine for manufacture allow for the mass production of high altitude balloons and minimize necessary material handling. The perimeter border strip can be dispensed and guided relative to the perimeter of the balloon panels for positioning before sealing together, as a bonding device is rotated relative to the balloon envelope.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

A method of making an aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The method has the steps of sealing the valve to the product delivery device and outer container at respective annular welds or other bonds joining the valve to the product delivery and to the outer container. The welds, or other bonds may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes. Suitable welds include spin welds.

The machine (1) comprises at least one main welding device (3) of a first profiled element (4) and a second profiled element (5) which extend along their respective longitudinal directions and are each provided with at least one extremal area to be welded (6), the main welding device (3) comprising: main retaining means (18, 19) of the profiled elements (4, 5); main heating means (20) adapted to heat the extremal areas to be welded (6); main displacement means (21) of the main retaining means (18, 19) adapted to displace the profiled elements (4, 5) between a mutual spacing away position and a mutual approaching position;
wherein the main heating means (20) comprise two heating plates (27), each of which can be placed in contact with a respective extremal area to be welded (6) and arranged substantially parallel to each other at a predefined distance to define a free volume (V) positioned between them.
