摘要:
A conductor assembly and method for constructing an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one embodiment the method provides a first insulative layer tubular in shape and including a surface along which a conductor segment may be positioned. A channel formed in the surface of the insulative layer defines a first conductor path and includes a surface of first contour in cross section along a first plane transverse to the conductor path. A segment of conductor having a surface of second contour in cross section is positioned at least partly in the channel and extends along the conductor path. Along the first plane, contact between the conductor surface of second contour and the channel surface of first contour includes at least two separate regions of contact.

Process of adhering conductors such as bare copper wire, copper wire with polymide insulation, and multistrand Kapton wrapped superconductors to mount structures such as a cylinder of arbitrary cross sections, a saddle support, or steel tubes using adhesive layers of material such as BONDALL 16-H, 3M-2090 and T-164. The adhesive layers are subject to b-staging before being used, where it is heated to a temperature of approximately 60-100.degree. C. for approximately 1/2 hour to approximately one hour. The support surface can optionally be grooved to allow for better wire placement and no wire slippage.

A segment of a structure mitigates flow of fluid therethrough. In one embodiment the segment includes an opening for the fluid flow and the modified structure may include a ferromagnetic wall defining the opening and a plurality of permanently magnetized particles. Some of the permanently magnetized particles are attached to the wall by magnetic forces. A system is also provided for injecting magnetic particles into a cavity to impede movement of fluid through the cavity. A method is also described for mitigating a flow of fluid through an opening in a wall. In one embodiment, the method includes positioning a plurality of first magnetic particles along the wall and about the opening and attaching a plurality of second magnetic particles to the first magnetic particles wherein some of the second magnetic particles collectively extend across the opening to cover the opening.

A conductor assembly and method for constructing an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one embodiment the method includes providing a first insulative layer having a curved surface along which a conductor segment may be positioned, and forming a channel in the insulative layer, which defines a first conductor path. The channel includes first and second opposing channel surfaces each extending from the surface of the insulative layer into the insulative layer and a third channel surface extending between the first and second channel surfaces. Each of the first and second channel surfaces includes a substantially flat surface portion with the surface portion of the first channel surface parallel with the surface portion of the second channel surface. A first segment of conductor is placed in the channel.

A conductor assembly and method for constructing an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one embodiment the method includes forming a structure comprising layers of material extending along a first aperture path. The structure includes multiple concentric layer surfaces. A channel is formed in each of the layers of the material and along each of the multiple surfaces. Conductive material is positioned in each channel to provide a spiral configuration. The surfaces of multiple ones of the layers are of tubular shape. The layers of material are sequentially positioned one over another and about an axis along which first and second opposing coil end regions are formed. The layers are formed with a region of a first thickness and a shoulder region. The shoulder region is alternately formed in the sequence at one coil end region or at the other coil end region. Each shoulder region has a greater thickness than the first thickness.

A conductor assembly and method for constructing an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one embodiment the method provides a first layer that is tubular in shape with an outer surface along which a conductor may be positioned. A channel defining a first conductor path is formed in the first layer outer surface to create a pattern extending along the first layer. A first segment of conductor is placed in the first channel and defines a shape about an aperture region. After placing the first segment of conductor in the first channel, at least part of the first layer outer surface and at least part of the first segment of conductor are coated with a second layer. A second channel is formed along an outer surface of the second layer to define a second conductor path extending about the aperture region for placement of a second segment of conductor.
