20090202194 | OPTICAL MEASURING DEVICE FOR DETERMINING TEMPERATURE IN A CRYOGENIC ENVIRONMENT AND WINDING ARRANGEMENT WHOSE TEMPERATURE CAN BE MONITORED - An optical measuring device for determining temperature in a cryogenic environment includes at least one optical waveguide provided with at least one fiber Bragg grating sensor that is interrogated by a light signal. The device includes a light injector that injects light into the at least one fiber Bragg grating sensor, and an evaluation unit that determines a temperature value from the modulated light signal emanating from the at least one fiber Bragg grating sensor. The device includes at least one jacket that non-rigidly encloses the optical waveguide, at least in the region of the at least one fiber Bragg grating sensor. The jacket has a larger coefficient of thermal expansion, at least at cryogenic temperatures, than the optical waveguide. A winding arrangement for use in a cryogenic environment is provided with such a device for temperature monitoring of a conductor of the winding arrangement. | 08-13-2009 |

20120061139 | Superconductive Connecting Device For The End Pieces Of Two Superconductors And Method For The Production Thereof - A superconductive connecting device of at least one embodiment is used to contact the end pieces of two superconductors, each of which includes at least one conductor lead that is made of a superconductive MgB | 03-15-2012 |
20120105063 | SUPERCONDUCTIVE MAGNETIC COIL COMPRISING REGIONS HAVING DIFFERING HEAT TRANSFER - A superconductive magnetic coil is located in a cryostat for cooling purposes which is filled only up to a certain fill level with liquid helium. A helium gas phase having a temperature stratification, in which, for example, temperatures are present that can lead to a collapse of the superconductivity, forms over said helium accumulation. The magnetic coil is therefore subdivided into at least two partial regions having differing heat transfer between the coil and the surrounding medium. In a first partial region of the coil, in the surroundings of which a sufficiently low temperature for cooling is present, the heat transfer is high, while the magnetic coil in a second partial region, in the surroundings of which the temperature of the cooling medium is above a critical value, exhibits heat insulation. Consequently, no heat is exchanged between the coil and the surroundings in the second partial region, while cooling of the coil takes place in the first partial region. | 05-03-2012 |
20120184446 | PROCESS FOR PRODUCING A CONNECTING STRUCTURE BETWEEN TWO SUPERCONDUCTORS AND STRUCTURE FOR CONNECTING TWO SUPERCONDUCTORS - A process produces a connecting structure between two superconductors, in particular magnesium diboride superconductors embodied as a superconducting core wire surrounded by normally conducting metal. A substance which reduces the melting point of magnesium is admixed to a substance mixture including magnesium and boron, and the exposed ends of the core wires are brought into contact with the substance mixture, which is caused to react in situ at a reaction temperature corresponding to the lower melting point to give magnesium diboride. | 07-19-2012 |
20130172196 | HIGH-TEMPERATURE SUPERCONDUCTOR (HTS) COIL - A high-temperature superconductor (HTS) coil includes a coil winding with a superconducting material and a coil former for carrying the coil winding. When the high-temperature supercon-ductor (HTS) coil cools down from a room temperature to an operating temperature, the coil winding or the coil former counteract a thermal shrinkage of the coil winding in order to avoid or reduce a longitudinal compression of the superconducting material of the coil winding. | 07-04-2013 |
20130331269 | Coil System for a Magnetic Resonance Tomography System - A coil system for a magnetic resonance tomography system includes a plurality of coils for sending and/or receiving high-frequency signals. The plurality of coils is disposed in a receiving chamber between a tomography magnet and a lining of an opening in the tomography magnet and may be cooled by a cooling apparatus. When the coil system is in an operating state, the receiving chamber is filled with a cryogenic cooling medium. | 12-12-2013 |
20140312999 | WINDING SUPPORT, ELECTRICAL COIL AND METHOD TO PRODUCE AN ELECTRICAL COIL - A winding support has at least two parts on which to wind an electrical double coil in two winding planes situated in parallel, orthogonal to a winding axis. Each part has an annular structure with base areas that are identical for all of the parts, and an outer surface that is a band of the surface of a straight cylinder between the bases. Each part has a slit-shaped cut-out extending in a longitudinal direction over a portion of the length of the cylinder. The parts are adjacently connected with one another with a lateral separation therebetween in the direction of the winding axis, and with the cut-outs forming a common slit extending over both parts. An electrical coil has such a winding support, and a method to produce such a coil includes winding a conductor on such a winding support. | 10-23-2014 |
