20100108318 | METHOD AND DEVICE FOR THE IN-SITU EXTRACTION OF A HYDROCARBON-CONTAINING SUBSTANCE, WHILE REDUCING THE VISCOSITY THEREOF, FROM AN UNDERGROUND DEPOSIT - A device for the in-situ extraction of a hydrocarbon-containing substance, while reducing the viscosity thereof, from an underground deposit, has at least one injection pipeline extending in the deposit and at least one production pipeline leading out of the deposit, which together form a so-called well pair. The injection and production pipelines each have a starting region extending above ground in some areas, and an active region connecting to the starting region inside the deposit. With the method, during a heating phase hot steam is applied to the injection and production pipelines, while during a production phase hot steam is applied only to the injection pipeline. Furthermore, the active region of the injection pipeline is additionally configured as an induction heater regarding the surrounding area in the deposit. In the associated device, for example, the well pair formed by the injection pipeline and production pipeline can be configured as electrodes. | 05-06-2010 |

The industrial turbine may be a gas turbine or a steam turbine. In particular the industrial turbine with downstream generator is assigned a waste heat recovery steam generator which serves for generating the steam and accordingly takes the form of a boiler. Through intermediate storage of the bitumen and/or ultra-heavy oil produced it is possible to implement a self-contained closed circuit which operates autonomously, independently of any external energy supply, using approx. 20% of the extracted bitumen and/or extra-heavy oil for the purposes of extraction. | 09-22-2011 |

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 |
