20100028123 | SUPERCONDUCTING CRAWLER SYSTEM FOR A PRODUCTION LINE - A method of operating a production line comprises the steps of supporting equipment in the production line on a plurality of crawlers comprising at least one rolling track and a structural support for supporting the equipment. A first plurality of lifting magnets coupled to an interior surface of said at least one rolling track is configured to oppose a second plurality of lifting magnets coupled to an exterior surface of said structure support to lift the structural support, such that the structural support floats between and within said at least one rolling track. The magnetic fields experienced by the first and second plurality of lift magnets are adjusted to translate the at least one rolling track, such that the crawlers move along the production line. | 02-04-2010 |
20100038986 | Brushless Motor/Generator With Trapped-Flux Superconductors - Apparatus and methods provide for a high specific power electro-dynamo device that utilizes high-temperature superconductors, a dysprosium core, and superconducting coils to provide power. According to various embodiments, a rotor includes a number of rotor arms with a high-temperature superconductor attached to each arm. A stator includes a number of stator arms with stator coils wrapped around each arm. The stator coils may include superconducting wires for providing a charge to the high-temperature superconductors and non-superconducting wires for inducing a voltage from the trapped flux provided by the superconductors during operation in generator mode. The dysprosium core maximizes the magnetic flux saturated by the core while providing additional safety measures during operation. A backup power wheel or permanent magnets positioned in series with the high-temperature superconductors may provide emergency power at non-cryogenic temperatures. | 02-18-2010 |
20100045130 | Superconducting Pulsed-Power Source - Methods and systems provide pulsed-power to a load utilizing high temperature superconductors (HTS) within multiple pulsed-power devices. According to embodiments described herein, each pulsed-power device includes a HTS mounted on a rotor and an armature coil mounted on a stator. The rotor is positioned to allow a magnetic field within the HTS to induce a voltage in the armature coil when the rotor is rotating and to allow a magnetic field created by passing current through the armature coil to charge the HTS. Current created from the operation of a first pulsed-power device is routed to the armature coil in a second pulsed-power device to charge the associated HTS to a higher value. Subsequently, the second pulsed-power device is operated to produce current that is used to further charge the HTS in the first pulsed-power device. This bootstrapping procedure is repeated until all HTSs are fully charged. | 02-25-2010 |
