    摘要： A conformal skate for use in an inductive welding system for creating a fusion bond along a bond line between two thermoplastic parts includes a wheel having a circumferential casing made of fluid impervious flexible material. The wheel is rotatably mounted on a fixed axle by fluid tight bearings. The axle has an axial passage for admission of pressurizing and cooling fluid, and for power leads for the coil and for leads for sensors inside the wheel. A vertical mount on the axle supports the coil for vertical motion and biases the coil downwardly so that it remains in contact with the inside surface of the casing despite unevenness or contour changes in the upper surface of the top part or changes in the wheel shape when the fluid pressure in the wheel or downward force on the axel is changed. A supporting member such as a strut or frame supports the axle and applies the downward force which the wheel distributes over the footprint in contact with the top part, in line with the magnetic field generated by the coil. The size of the wheel footprint is a function of the amount to liquid in the wheel and the force exerted by the supporting member, which pressurizes the fluid sealed in the vessel and distributes pressure uniformly over the footprint of the wheel to press the top part against the bottom part and facilitate fusion bonding of the thermoplastic in the melt pool created by the inductively heated susceptor.

    摘要： Magnetic flux trapping clamps are provided that trap or pin the magnetic flux of ring shaped superconductive magnets in a high permeability metallic core located in the bore of the ring. Preferably, the superconductive magnets comprise a single crystal cut into a ring shape. Multiples of the flux-pinned magnets, having high magnetic strength, can be arranged in a variety of arrays for a range of applications. The devices offer several advantages over permanent or electromagnets. The devices easily activated by charging with a cryogenic fluid, to induce the superconductive effect, and deactivated by draining the fluid.

    摘要： Fluid tooling for use in an inductive welding system for creating a fusion bond along a bond line between two thermoplastic parts includes an elongated vessel made of fluid impervious flexible material and having an elongated axis and an open end at each axial end of the vessel, closed and sealed by end closures. A coil is received in the vessel for generating an alternating magnetic field transverse to the longitudinal axis. A linear guide in the vessel extends axially for substantially the full length of the vessel and guides the coil for movement axially through the vessel. Power leads are connected to the coil and extend through a pass-through in one end closure to connect the coil to a source of high frequency electrical power of about 35 KHz to energize the coil to produce an alternating magnetic field. A pair of magnets guided along opposite sides of the vessel and magnetically coupled to a ferromagnetic mass connected to the coil move the coil axially along the vessel over the bond line at a controlled speed. A backup structure exerts a downward force along the top of the vessel, pressurizing fluid sealed in the vessel and distributing pressure uniformly over the top surface of the top part to press the top part against the bottom part and facilitate fusion bonding of the thermoplastic in the faying surfaces of the interface.
