  • Patent number: 9027869
    Abstract: A filament winding apparatus prevents a fiber bundle supplied to a liner from interfering with other fiber bundles and fiber supplying guides. First and second guide units include a plurality of fiber supplying guides arranged radially and extending and contracting in a direction approximately perpendicular to a liner central axis. When a fiber bundle supplied from a first supplying guide of the first guide unit crosses between a second supplying guide of the second guide unit and the liner, the distance from the second supplying guide to the liner central axis is made larger than the distance from the first supplying guide to the liner central axis, and in the reverse case, the distance from the first supplying guide to the liner central axis is made larger than the distance from the second supplying guide to the liner central axis.

  • Patent number: 8967521
    Abstract: A filament winding device that optimizes the interval between adjacent fiber bundle guides includes a plurality of helical heads on which fiber bundle guides moving in the direction that is roughly perpendicular to the rotating axis of a liner are radially disposed; and winds a fiber bundle onto the outer circumference surface of the liner by passing the helical heads while rotating the liner. An interval adjusting means adjusts the interval between a virtual plane (Pf) which intersects with the guiding opening of a fiber bundle guide disposed on one of the helical heads so as to be orthogonal to the liner rotating axis and a virtual plane (Pw) which intersects with the guiding opening of a fiber bundle guide disposed on the other helical head so as to be orthogonal to the liner rotating axis.

  • Patent number: 7915990
    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.

  • Patent number: 7798441
    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.

  • Patent number: 7377465
    Abstract: A wire/fiber ring having two layers applied in four clock positions. Each layer includes a first material strand having a first diameter and a second material strand having a second diameter different from the first diameter. A second or any subsequent layer is disposed such that there is unambiguous nesting between strands in adjacent layers. After the array is built-up, wire is over-wrapped around the array to hold it in place during subsequent consolidation steps, which take place after the built-up array is sealed in an air-tight container and evacuated. After heating and application of pressure a wire/fiber array having a void content of about 12% and a fiber content of between about 0% to 70% and preferably between about 30% and 45% can be achieved.

  • Patent number: 7201344
    Abstract: In a multilayer coil which winds “n” wire rods (4) (“n” is an integer number of two or more) in line around a winding core (2) having a cross section of a polygonal shape. An intersection portion (5) is formed on a face where feeding of the winding core is made by feeding the wire rods by an amount of “n” wire rods during a period when the wire rods (4) are wound by one round around the winding core (2), so that the wire rods in a lower layer and an upper layer intersect therein. A twist portion (6) is formed at an end of at least one face out of the faces where the feeding is made, wherein two wire rods out of “n” wire rods are twisted to replace an arrangement of the wire rods.

  • Patent number: 6921042
    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.
