| 20110260814 | CONTINUOUSLY WOUND SOLENOID COIL WITH FINAL CORRECTION FOR GENERATING A HOMOGENEOUS MAGNETIC FIELD IN THE INTERIOR OF THE COIL AND ASSOCIATED OPTIMIZATION METHOD - Disclosed is a device for generating a uniform magnetic field and to an optimization method for magnetic fields in a sample space, the method providing specifications for producing such a device. The device comprises at least one field coil for generating the magnetic field and the turns of the field coil are continuously wound around the sample space and the turn diameter of the field coil changes continuously at least in a portion of the field coil along the longitudinal axis of the sample space. To this end, the correction of non-uniformities in the magnetic field caused by the finite length of the field coil is distributed over the entire field coil. In this way, the device can be implemented more easily and precisely than with the correction coils used according to the prior art for correcting non-uniformities. Instead of the existing series expansion of the magnetic field, the method for optimizing the magnetic field employs a power function in conjunction with simulation of the magnetic field based on the optimization parameters. This function can be used in a larger volume than the series expansion. | 10-27-2011 |

| 20090299005 | Method for Inreasing the Efficiency of Surfactants, Extending the Temperature Window, and Suppressing Lamellar Mesophases in Microemulsion by Means of Additives, and Microemulsion - A method for increasing the efficiency of surfactants, broadening the temperature window, and suppressing lamellar mesophases in microemulsions by use of additives that possess at least one water-soluble unit and one hydrophobic unit are added to the microemulsions. The ratio of the number-average molecular weight of water-soluble units to the number-average molecular weight of hydrophobic units is 2 to 1000, the additives being polymers that comprise at least one water-soluble unit that possesses at least one hydrophobic unit on one chain end and/or one hydrophobic unit as a non-terminal substituent and/or at least one hydrophobic unit that is incorporated between the water-soluble units of the polymer. | 12-03-2009 |
| 20090213866 | Data Communication System And Method - A data communication system having a plurality of input/output ports, a first group and a second group of switching units. Each switching unit has a plurality of input/output interfaces, whereby at least one of the plurality of input/output interfaces of each switching unit of the first group forms an input/output port of the communications system, and at least one other input/output interface of each of the switching units of the first group is connected via a communication link with an input/output interface of one of the switching units of the second group, so that a network is formed having at least one loop. The network is logically divided in at least two virtual subnetworks, each forming a spanning tree. Each switching unit of the first group is configured to assign an incoming data packet arriving at a particular input/output port to a predetermined one of the at least two virtual sub-networks. An advantage of the present invention is the ability to transparently employ the taught data communication device in different computing environments, without the requirement to alter any external equipment. | 08-27-2009 |
| 20080245446 | Protective Layer for an Aluminum-Containing Alloy for High-Temperature Use - Alloys containing aluminium are characterised by an outstanding oxidation resistance at high temperatures, that is based on, inter alia, the formation of a thick and slow-growing aluminium oxide layer on material surfaces. If the formation of the aluminium oxide layer reduces the aluminium content of the alloy so far that a critical aluminium concentration is not reached, no other protective aluminium oxide layer can be formed. This leads disadvantageously to a very rapid breakaway oxidation, and the destruction of the component. This effect is stronger at temperatures above 800° C. due to the fact that, often at this point, metastable Al | 10-09-2008 |
| 20080231268 | Imaging Method Based on Fractal Surface-Filling or Space-Filling Curves - The present invention relates to an imaging method and device for nuclear magnetic resonance. On the one hand, the method provides an image coding by means of an additional field which has, for each point of a two-dimensional grating surface within the sample, a different field strength value that occurs only once, as is the case, e.g., in fields based on fractal, surface-filling and space-filling curves. On the other hand, the read-out of the resonance behavior of a sample along a space-filling and/or surface-filling curve can be provided. In the first variant, a magnetic resonance (MR) image with a single high-frequency excitation without a time-varying gradient can be recorded, which in turn advantageously prevents the sound generation associated therewith. In the second variant, the sounds generated during read-out are advantageously shifted to another frequency range in which the human hearing is less sensitive. Furthermore, the device is relieved and the technical requirements with regard to it are reduced. In addition, it can be executed with known and existing devices. | 09-25-2008 |
| 20080220229 | Method for Structured Application of Molecules to a Strip Conductor and Molecular Memory Matrix - The invention relates to a method for a structured application of molecules on a strip conductor and to a molecular memory matrix. The inventive method makes it possible, for the first time, to economically and simply apply any number of molecular memory elements on the strip conductor in a structured and targeted way, thereby making available, also for the first time, a memory matrix at a molecular level. | 09-11-2008 |
