Abstract: 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.

Abstract: A filament winding apparatus includes a hoop winding device and a helical winding device. The hoop winding device includes a disc-shaped wrapping table, a drive mechanism that rotatably drives the wrapping table, four bobbins supported along a peripheral edge of the wrapping table, and a guide member that moves and guides a fiber bundle fed from the bobbin to a mandrel arranged in an insertion hole of the wrapping table. The bobbin is axially supported in a freely rotatable manner with a chuck of a holder fixed to the wrapping table. A ratchet mechanism, which prevents over-rotation in a fiber bundle feeding direction of the bobbin, is arranged between the holder and the chuck.

Abstract: A conductor assembly of the type which, when conducting current, generates a magnetic field or in which, in the presence of a changing magnetic field, a voltage is induced. A helical wiring pattern is positioned along an axis a radial distance R from the axis. The wiring pattern is formed about an aperture region extending from the axis toward the wiring pattern, the distance R varying along a portion of the axis.

Abstract: A filament winding apparatus that efficiently and orderly winds a fiber bundle with respect to a mandrel in a short period of time. A supporting board supports the mandrel, and a helical winding head supplies and guides the fiber bundle towards the mandrel. The helical winding head includes a group of guide tubes radially arranged on a circumferential surface of a guide ring, and a tube operation mechanism that reciprocates the guide tube along a tube axis center direction. The guide tube is moved closer to a circumferential surface of the dome part when the guide tube is facing a dome part of the mandrel such that the distance between the winding position of the fiber bundle and the guide tube at the dome part can be reduced, and the fiber bundle is orderly wound according to an appropriate winding trajectory.

Abstract: 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.

Nos. 6,491,779, 6,804,942, and 7,073,978, wherein said improvement provides for void space or otherwise insulating region along the length of the tubing. The present invention is additionally directed to methods for implementing such improvement.

Abstract: Concentric tilted double-helix magnets, which embody a simplified design and construction method for production of magnets with very pure field content, are disclosed. The disclosed embodiment of the concentric tilted double-helix dipole magnet has the field quality required for use in accelerator beam steering applications, i.e., higher-order multipoles are reduced to a negligibly small level. Magnets with higher multipole fields can be obtained by using a simple modification of the coil winding procedure. The double-helix coil design is well-suited for winding with superconducting cable or cable-in-conduit conductors and thus is useful for applications that require fields in excess of 2 T. The coil configuration has significant advantages over conventional racetrack coils for accelerators, electrical machinery, and magneto-hydrodynamic thrusting devices.
