The present invention relates to a method for joining at least two flexible foils (10a-b). The method comprises the steps of (i) providing a first flexible foil (10a) having a first row (12) of light emitting diodes (14) and a first set of electrically conductive tracks (16) for supplying current to the first row (12) of light emitting diodes (14), (ii) providing a second flexible foil (10b) having a pot second row (12) of light emitting diodes (14) and a second set of electrically conductive tracks (16) for supplying current to the second row (12) of light emitting diodes (14), and (iii) joining the first flexible foil (10a) and the second flexible foil (10b) at an overlap (22) of the first flexible foil (10a) and the second flexible foil (10b), wherein a metal strip or wire (24; 24) gets embedded between the first flexible foil (10a) and the second flexible foil (10b) at the overlap, and wherein the metal strip or wire (24; 24) electrically connects to the first and second sets of electrically conductive tracks (16).

A method for manufacturing a current collector head for a current collector consisting of an electrically conductive contact shoe and an electrically insulating contact shoe holder includes the following steps: inserting a section of the contact shoe into an outwardly open cavity in the contact shoe holder dimensioned to match this section; clamping the contact shoe in the cavity of the contact shoe holder by acting on the contact shoe holder with at least an external force directed onto the inserted section of the contact shoe; heating the contact shoe to a temperature sufficient to form a bonded connection with the contact shoe holder; and cooling the current collector head formed from the contact shoe and the contact shoe holder.

A cover for a housing of a vehicle and a method of sealing a cover to the housing, where in at least one example, the cover comprises a cover body configured to cover an opening of the housing and to engage the housing at an interface around the opening. The cover may comprise a heating element embedded within the cover body and operable to at least partially melt a portion of the cover body as a part of a process for sealing the cover to the housing. The portion of the cover body may deform and conform to an interface feature at the mating surface of the housing due to the at least partial melting of the portion of the cover body, and, in some examples, the heating element may be configured to fail and be inoperable.

A method and an annular integral gasket are provided for forming a sealing connection between a first tubular member and a second tubular member. The integral gasket comprises at least one flexible sealing portion adapted to form a sealing connection between a first tubular member and a second tubular member. The integral gasket further comprises a bonding layer adapted to be fixedly attached to a tubular member by a joining process. The integral gasket also comprises a body region adapted for supporting the flexible sealing portion and the bonding layer.

A method for producing a molding, the shape of which is adapted to an initial mold, in which method a plurality of layers are deformably placed on top of one another such that the layers can be joined to each other by heat. The layers are deformed by being pressed onto the initial mold and in order to join the layers. Heat is applied in the deformed state. In the arrangement made of layers, at least one converter element is introduced that transforms supplied energy into heat energy and with which at least parts of the layers are heated to join the layers.

A method for forming a shim. A liquid shim material with a magnetically permeable material is applied in a location for the shim between a plurality of composite parts. A magnetic field is applied to the magnetically permeable material in the location. The magnetic field is configured to heat the liquid shim material to a temperature to cause the liquid shim material to become solid and form the shim.

The present techniques provide a novel electrolyzer and methods for welding components of such electrolyzers. The techniques may use conductors, such as resistance wires, placed in paths around the internal structural features and edges of the components. The conductors may be incorporated into the components during manufacture by injection molding, or other molding techniques, or may be tacked or otherwise applied to the surface of the components after manufacture. When current, a field or other excitation is applied to the conductors, the plastic surrounding the wire is melted. If this plastic is in direct contact with an adjoining component, a strong, hermetic seal may be formed between the two components, including the internal structural features.

A structure and method of forming a metal foil-less liner, such that the entire liner can be recycled in a respective paper or plastic recycling stream. A separate application device is provided, which includes a metal layer, that is used to induction heat seal the liner to the container rim. The application device is removable, allowing a plastic closure cap to be applied over the liner sealed container rim, to provide the final product for sale to the consumer, who then removes the cap and peels off or pierces through the liner to dispense the product through the open mouth of the container. The application device is also reusable, i.e., it can be used to attach a subsequent liner to another container rim. The result is a liner that is fully recyclable in a paper or plastic recycling stream. In one embodiment, the entire container package may be recyclable, namely the plastic container is recyclable in a plastic recycle stream, the plastic container cap is recyclable in a plastic recycle stream (same or different than the recycle stream for the container), and the entire liner is recyclable in a paper or plastic recycle stream (which may be the same as one or more of the recycle streams for the container and cap). The result is also a sustainable packaging solution where the application device that generates heat for induction heat sealing can also be re-used.
