Abstract: A filter system includes a body having an inlet and an outlet fluidly coupled with the inlet by one or more passageways. The one or more passageways are shaped to direct a fluid having particles through the body from the inlet toward the outlet. The one or more passageways may rotate the fluid in one or more cyclonic directions. A lattice component is disposed within the passageways and includes one or more openings through which the fluid passes as the fluid moves in the one or more cyclonic directions. The passageways are shaped to remove a first portion of the particles from the fluid, and the lattice component is shaped to remove a second portion of the particles from the fluid such that the fluid exiting from the body via the outlet has fewer of the particles than when the fluid entered the body via the inlet.

Abstract: A structural lug comprising a metallic base, composite middle layers, and outer layers of metallic material is disclosed. The metallic base of the structure is machined to accommodate the composite plies, which are located on each lateral side of the base and bonded to the base with adhesive. The composite material may comprise an adhesive-based resin with embedded fibers. The metallic base may be formed to minimize peel stresses in the composite layers. The top metallic layers are fitted over and bonded to the composite plies and act as the outermost layers of the lug. The lateral ends of the lug where the top layers come into contact with the machined base may be joined together with friction stir welding or mechanical fasteners to form the completed structure.

Abstract: A foldable container (1) for picnics comprising a foldable blank (2) connected to a sheet of material (3). When the blank (2) is folded it is used to carry a picnic, and when unfolded, the sheet (3) can be spread out to allow users to eat the picnic.

Abstract: Embodiments in the present invention provide a system and method of joining structural members. This method involves aligning the first structural member to a metallic substrate when the first structural member has at least one tapered hole or cavity. A metallic or other like material suitable to cold spraying technology is deposited into the tapered cavity to form a shaped or tapered fastener bonded to the metallic substrate. The shape of the fastener secures the first structural member to the metallic substrate. Additionally, a protective insert may be placed within the shaped or tapered cavity to protect the first structural member during hoe cold spraying deposition when the first structural member is a composite material or other like material susceptible to erosion during the cold spraying technique.

Abstract: A metallic-composite joint is formed by inserting a metallic member into a slot of a pi-shaped composite preform. The preform is formed from woven carbon fiber in a binder of resin and may or may not be cured prior to assembly. An inert compliant layer is located between the legs of the preform and the metallic member. The resin binder or an adhesive is used to bond the compliant layer to the preform. The compliant layer has a coefficient of thermal expansion that more closely matches that of the preform. The properties of the compliant layer also avoid galvanic corrosion between the carbon in the preform and the metallic member.

Abstract: Friction stir welded joints are reinforced with a strengthening material that is applied directly to the joint surfaces to counteract the loss of desirable physical properties in the workpieces being joined. The strengthening material is stirred into the weld nugget during processing and locates at the bond interfaces to form a more robust joint. The reinforcing substance is distributed throughout the nugget and counterbalances the loss of strength due to dissolution of the precipitates during processing.

Abstract: A three dimensional joint is formed by coupling (joining) a first structural member and a second structural member. This involves first aligning a first structural member to a second structural member. The first structural member has a channel with which to receive a portion of the second structural member. Certain embodiments may place corrosively inert materials within the mating surfaces to prevent or inhibit corrosion or oxidation. Once aligned, the first structural member and second structural member may be friction stir welded at the channel to plasticize the material adjacent to the channel of both the first structural member and the second structural member to form a friction stir weld joint. Embodiments may then coat the plasticized surfaces of the FSW joint with cold sprayed materials to inhibit corrosion. Should a crack occur within either the plasticized or non-plasticized materials, cold sprayed material may be deposited within and on the crack to retard or arrest the growth of the crack.

Abstract: A method for joining a first structural member and a metallic substrate is provided. This method involves drawing projections from a metallic substrate using a Co-Meld or other like process. Individual plies of composite materials may be laid upon the metallic substrate and projections. These projections penetrate the individual ply or layers of the composite material. A mechanical feature that serves as a retaining device may be located at the distal end of the projections in order to prevent separation of the composite materials from the metallic substrate. The composite materials may be infused with a resin or other material to complete the formation of the composite material. Additionally, other layers of composite material may be placed over the mechanical features located at the distal ends.
