Embodiments can include a self-reacting friction stir weld ('FSW') tool. The device can be configured to be portable and produce full penetration welds in situ. The FSW tool can include a system that cuts out a portion of the structure surrounding a defective portion of the structure. A work-piece can be inserted within the removed portion and friction stir welded to the structure via the FSW tool. A superior repair as compared to merely welding the defect can be achieved by replacing a portion of the structure surrounding the defect as opposed to merely welding the defect (e.g., the crack). A controlled geometric shaped weld beam can be generated for the interface between the work-piece and the structure, which may led to a stronger, more reliable weld.

A system for bundling a plurality of high temperature superconductor tapes into a flexible cable, includes a first alignment device for receiving and guiding there through the plurality of high temperature superconductor tapes, each of the tapes arranged with a wide surface oriented at a first angle. There is a second alignment device for receiving and guiding there through the plurality of high temperature superconductor tapes, each of said tapes arranged with the wide surface oriented at a second angle. The first angle is transverse to the second angle and plastically deforms the tapes to impart a twist pitch in the tapes. There is a forming member spaced from the second alignment device for receiving the plurality of high temperature superconductor tapes with the imparted twist pitch and forming them into a bundle of high temperature superconductor tapes of the high temperature superconductor tapes with the imparted twist pitch.

A segmented track made of a plurality of elastomeric track segments is provided. Each track segment is made of reinforced elastomeric material and is provided, at each end thereof, with a joint element adapted to be connected to the joint element of adjacent track segments. Each track segment comprises longitudinally extending reinforcing elements which are embedded into the elastomeric material and which are extending between and coupled to both joint elements.

Segmented track

A feed shoe having at least one feed chamber with an open bottom portion and an open front portion whereat a gate is provided. The gate can be vertically adjustable and can have a lower edge defining a leading edge of the feed chamber, wherein the leading edge can have a flat, serrated, or rounded profile depending upon the type of feed material used. The gate, or a separate main gate adjacent the gate, can have a flat, curved, or V-shaped inner surface facing the feed chamber, wherein a lower portion of the inner surface can have a stepped profile which shears the material in the feed chamber in separate planes. The feed shoe can further include an attachment portion adapted for adjustably retaining an end of at least one material feed delivery member in communication with said at least one feed chamber.
