摘要： A superconductor structure is manufactured by forming a channel within a substrate along a surface of the substrate, depositing a material within the channel of the substrate, where the material includes one of a superconductor material and a precursor for a superconductor material, and thermally treating the substance within the channel of the substrate so as to form an elongated superconductor wire formed as a single, cohesive structure. The substrate can further include a plurality of channels with superconductor wires formed within the channels. In addition, a cable is formed including a bundle of individual superconductor wires arranged at different spatial positions with respect to each other.

摘要： A packer for downhole use features interacting elements of swelling material. Preferably the elements are in contact for relative movement from an initial diameter for run in. As the elements swell, they move with respect to each other to enlarge the diameter of the assembly so that a sealing contact is made. Each element exerts a residual force on the adjacent element to enhance the seal. Each element is preferably coated with a material that allows well fluids to reach the swelling material and then later to stiffen and become impervious from exposure to such fluids. The assembly can be covered for run in to delay the onset of expansion until the target depth is reached for the packer to be set.

摘要： A molten polymer filtration assembly includes at least three independently controllable and removable filter housings which extend from a common inlet passage to a common outlet passage, thereby providing parallel flow paths for polymer filtration. Each of the filter housings includes an inlet valve controlling the flow of polymer from the inlet passage, an outlet valve controlling the flow of polymer to the outlet passage, and a filtration passage which extends between the inlet and outlet valves and houses a candle-type filtration element. When the inlet and outlet valves are opened, the filter housing is on-stream and allows polymer to flow from the inlet to the outlet passage. Each filter housing is individually controllable, and can be set in an on-stream state independent of the state of any of the other filter housings, such that any number of filter housings can be on-stream at a given time. By setting the number of on-stream filter housing in correspondence with the polymer flow rate, the polymer residence time can be maintained in a relatively narrow range of durations over a wide range of polymer flow rates, thereby ensuring that the polymer residence time within the filtration system remains below an acceptable duration and that the polymer residence time is regulated to avoid significant fluctuation or variances in the polymer residence time. Interlocks prevent the closure of the outlet valve of each filter housing unless the inlet valve for that housing is closed. Removal of any filter housing is prevented unless its valves are both closed.

摘要： A spinneret (140) for extruding side-by-side bicomponent fibers includes a spinneret hole (148) having a cross-sectional shape transverse to the direction of polymer flow that is asymmetric with respect to the arrangement of the side-by-side streams of polymer components therein. The lower viscosity component flows through a portion of the spinneret hole having a higher perimeter-to-area cross-sectional shape than the portion of the spinneret hole through which the higher viscosity component through which the lower viscosity component flows. The increased surface area (i.e., cross-sectional perimeter) of the spinneret hole contacting the lower viscosity polymer flow compensates for the viscosity differential between the polymer components that would otherwise result in dogleg bending of the extrudate.

摘要： Nonwoven fabric is formed from a spunbond process by extruding generally ribbon-shaped fibers 126 through slot-shaped orifices 124 of a spinneret 122. The ribbon-shaped fibers are rapidly quenched after extrusion to achieve a substantially uniform molecular orientation throughout a transverse cross section of the fibers, yielding stronger fibers. The rapid quenching results largely from the relatively high aspect ratio (thinness) of the fibers and the relatively large surface area of the fibers, which permits the fibers to quickly cool throughout the transverse cross section. The ribbon-shaped fibers are drawn longitudinally by an aspirator 128 that exerts a generally downward force produced by an air stream that longitudinally stretches and transversely attenuates the ribbon-shaped fibers in such a manner that the transverse cross-sectional shape of the ribbon-shaped fibers enhances the interaction between the air stream and the ribbon-shaped fibers to maximize the downward force. The attenuated ribbon-shaped fibers are deposited onto a web forming surface 134, such as a moving wire screen belt to form a web. The web is then bonded to form the nonwoven fabric.

摘要： A spin-texture process for producing polyamide yarns is described in which a freshly extruded yarn is passed between two pairs of rotating rolls and then collected. The second pair of rolls (draw rolls) is driven at a peripheral speed greater than that of the first pair of rolls (feed roll and its associated separator roll). The feed roll is maintained and a given temperature which is correlated with other processing conditions to impart a desired level of latent crimp to the yarn. Yarns prepared by the process have a potential bulk of between 10% and 50% and are particularly useful as carpet yarns.

摘要： An apparatus for controlling airflow in a fiber extrusion process includes a fiber flow region between an inlet through which extruded fibers are received and an outlet through which the extruded fibers are discharged and at least one surface providing a boundary between the fiber flow region and another region, wherein the surface includes apertures permitting air to flow between the fiber flow region and the other region to control airflow at the outlet of the fiber flow region. The apparatus can include a housing which contains at least one chamber, with the surface forming a boundary between the fiber flow region and the chamber, such that the apertures permit air to flow between the fiber flow region and at the chamber. In a spunbond process, the airflow control device receives drawn filaments exiting an aspirator and deposits the filaments onto a web-forming surface with reduced air disturbance.
