The invention relates to a method for welding a polyamide plastic and a poly(meth)acrylateparticularly a polymethyl methacrylateplastic using a primer, said primer containing at least one copolymer synthesised from at least one styrene or styrene derivative and at least one maleic anhydride or maleic anhydride derivative. The invention also relates to correspondingly welded products.

A method for connecting the joint of two ends of at least one chassis sealing element. In order to allow a secure and quick connection of the ends and allow an additional unhindered passage of air and moisture between hollow chambers within the chassis sealing element via the joint when using a profiled hollow chamber, the ends are first arranged at a distance to each other, and a shapeless bonding agent is applied to at least one end. The bonding agent is then heated, and the ends are brought into mutual contact, whereby the ends are bonded at the joint by way of the heated bonding agent.

A device comprising a first fixing element, a further fixing element, and a folded planar composite is disclosed. The first fixing element comprises a first fixing surface and the further fixing element comprises a further fixing surface. The folded planar composite is at least partially fixed between the first fixing surface and the further fixing surface. The folded planar composite comprises a first composite region and a further composite region.

A microwave heating device includes a variable frequency microwave power supply, a waveguide launcher, and a fixture to contain a material to be heated, with the fixture located directly adjacent to the end of the launcher. All heating occurs in the near-field region. This condition may be insured by keeping the thickness of the fixture or workpiece under one wavelength (at all microwave frequencies being used). The launcher is preferably a horn or waveguide configured to apply the microwave power to a small area to perform spot curing or repair operations involving adhesives and composites. The spot curing may secure components in place for further handling, after which a thermal or oven treatment will cure the remaining adhesive to develop adequate strength for service. A related method is also disclosed.

A preform-charge fixture creates a preform charge, which is a partially consolidated assemblage of preforms that can be efficiently transferred to a mold to create a finished part in a molding process, such as compression molding. In the illustrative embodiment, the preform-charge fixture includes peripheral cleats that are movable towards a central cleat to create a small gap therebetween that receives and constrains preforms in a desired position. The fixture also includes clamps, which are operable to engage an uppermost layer of preforms in the gap and apply a slight amount of downward pressure thereto to assure that the preforms are properly seated. The fixture also accommodates an energy source that heats the preforms so that, in conjunction with downforce applied by the clamps and/or gravity, the preforms can be tacked together, forming the preform charge.

Implementations described herein include a system for guiding medical waste fluid into a medical waste collection canister. The system includes a manifold and a filter. The manifold includes a top surface and a sidewall extending from the top surface in a first direction. The top surface and the sidewall define an interior chamber of the manifold. The top surface includes an inlet port and a vacuum port disposed therein. The inlet port connects to a source of medical waste fluid and the vacuum port connects to a vacuum source. The manifold can be formed from a first polymer. A filter is positioned within the interior chamber of the manifold and immediately upstream of the vacuum port so as to filter air flowing into the vacuum port. The filter extends away from the top surface of the manifold in the first direction and the filter is formed from a second polymer. The filter is fused to a surface of the interior chamber of the manifold or to a peripheral surface of the vacuum port so as to form a fused interface, and not merely a press fit connection.

Described are methods for the manufacture of sporting goods, in particular a shoe, sporting goods manufactured by such methods, for example a shoe, as well as a device for performing such methods. The method for the manufacture of sporting goods, in particular a shoe, is provided, wherein the sporting goods has a first component with a first connection surface and a second component with a second connection surface. The method includes activating at least one portion of the first connection surface by providing heat energy without contact, and connecting the first component with the second component by joining the first connection surface and the second connection surface.

A process for producing a thermoplastic composite pipe is provided. The thermoplastic composite pipe thus produced contains a liner, two or more composite layers composed of tape laminas, and a single- or multilayer intermediate lamina arranged between different composite layers. Composite formation between identical polymers in the process achieves improved adhesion. The thermoplastic composite pipe is especially suitable for offshore applications in oil or gas production.

A microwave heating device includes a variable frequency microwave power supply, a waveguide launcher, and a fixture to contain a material to be heated, with the fixture located directly adjacent to the end of the launcher. All heating occurs in the near-field region, i.e., no cavity modes or standing waves are established within the fixture. This condition may be insured by keeping the thickness of the fixture or workpiece under one wavelength (at all microwave frequencies being used). The launcher is preferably a horn configured to spread the microwave power laterally over a selected area while maintaining a single propagating mode. The invention may be used to enhance catalytic reactions for research and other purposes. Alternatively, the invention may be configured to perform spot curing or repair operations involving adhesives and composites.
