Exposure of a leftover material at a cartridge that forms a vapor product is prevented. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, and a connection section whose one end is connected to the first component and whose another end is joined or welded to the second component. The first component includes a first facing surface that faces the second component, and a first outermost edge of the first facing surface. The second component includes a second facing surface that faces the first component, and a second outermost edge of the second facing surface. The first outermost edge and the second component are not joined or welded to each other, and the second outermost edge and the first component are not joined or welded to each other.

A battery assembly, such as a bipolar battery assembly, generally includes a first casing portion comprising an optically-absorbing region, and a second casing portion comprising an optically-transmissive region. The first and second features form a welded joint. Fabrication of such an assembly can include physically mating the first casing portion with the second casing portion, and irradiating, such as using a laser, the optically-absorbing region defining the first feature through the optically-transmissive region to form the welded joint.

A rotor blade assembly includes a rotor blade defining a pressure side and a suction side extending between a leading edge and a trailing edge. Further, the rotor blade assembly includes at least one structural feature secured within the rotor blade and spaced apart from the trailing edge to define a void between the pressure side, the suction side, and the trailing edge. Moreover, the rotor blade assembly includes an adhesive filling the void between the pressure side, the suction side, and the trailing edge to provide an adhesive connection between the pressure side, the suction side, the trailing edge, and the structural feature(s). In addition, the adhesive contacts the structural feature(s) at an interface and defines a fillet profile.

Systems and methods are provided for utilizing stringer end caps. One embodiment is a method of forming a stringer. The method includes laying up a stringer preform comprising fiber-reinforced material, placing the stringer preform onto a skin panel preform, bonding an end cap to the stringer preform and the skin panel preform, and co-curing the stringer preform and the skin panel preform while the end cap is bonded to the stringer preform and the skin panel preform, resulting in a composite part that includes the end cap.

Exposure of a leftover material at a cartridge that forms a vapor product is prevented. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, and a connection section whose one end is connected to the first component and whose another end is joined or welded to the second component. The second component includes a facing surface that faces the first component, and an outermost edge of the facing surface. The other end of the connection section is joined or welded to the facing surface of the second component, at a position away from the outermost edge.

A leftover material is prevented from being generated from a part, of a cartridge that forms a vapor product, where positioning is performed. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, a connection section that extends between the first component and the second component, with one end connected to the first component and another end connected to the second component, and a guide section that extends from the first component, and that is not joined or welded to the second component. The second component includes a receiving section where the guide section fits.

Systems and methods are provided for utilizing stringer end caps. One embodiment is a method of forming a stringer. The method includes laying up a stringer preform comprising fiber-reinforced material, placing the stringer preform onto a skin panel preform, bonding an end cap to the stringer preform and the skin panel preform, and co-curing the stringer preform and the skin panel preform while the end cap is bonded to the stringer preform and the skin panel preform, resulting in a composite part that includes the end cap.

A liquid vehicle tank (1) having a wall made of a plastic material, the tank (1) comprising a component (3, 5) affixed to the wall, the component (3, 5) having a portion (10) embedded in the wall, the embedded portion (10) having an external surface (21) a part of which is chemically incompatible with the plastic material of the wall, wherein the tank (1) also comprises a strengthening element welded to the wall over the embedded portion (10) of the component (3, 5).

A battery assembly, such as a bipolar battery assembly, generally includes a first casing portion comprising an optically-absorbing region defining a first feature, and a second casing portion comprising an optically-transmissive region, the second casing portion defining a second feature, the second feature sized and shaped to mate with the first feature. The first and second features form a hermetic seal comprising a welded joint. Fabrication of such an assembly can include physically mating the first casing portion with the second casing portion, and irradiating, such as using a laser, the optically-absorbing region defining the first feature through the optically-transmissive region to form the welded joint. The first or second casing portions can include one or more casing segments that can support a battery plate, such as comprising a conductive substrate. A gasket or seal can be used such as to provide a further seal at or near a perimeter of the conductive substrate.

Induction Weldable Pipe Connectors (IWPCs) (400) for electromagnetic induction welding with at least one plastic pipe (30). IWPCs (400) include a tubular induction weldable mounting (401) having an opposite pair of induction weldable sockets (404A, 404B), a tubular cover (406) externally mounted on the induction weldable mounting (401), and a tubular pipe tang (407) internally disposed in one induction weldable socket (404A, 404B) for destining an induction weldable socket (404A, 404B) as an induction weldable pipe socket (408A, 408B) for forced sliding insertion of a pipe end (31) thereinto. The cover (406) includes an opposite pair of thermally insulated induction weldable socket mouth rims (426A, 426B) for entrapping melted solder lining (412) inside the induction weldable mounting (401) during an electromagnetic induction welding operation, thereby ensuring improved welding.
