20130091870 | Cold gas supply device and NMR installation comprising such a device - A device for supplying cold gases to an NMR installation or analytical apparatus equipped with a measuring probe, with cold gases ensuring the cooling of the sample contained in the probe, but also its lift and rotation, the device including an insulated tank containing liquid gas at boiling point and in which are arranged exchangers through which gas streams to be cooled pass, these exchangers being connected to transfer lines channeling the cooled gases to the probe. The device also includes at least one additional exchanger that ensures a pre-cooling of the gas stream before it is channeled to the corresponding exchanger, with the or each additional exchanger coming in the form of a double-flow exchanger that is supplied either by the gaseous vapor produced by the boiling of the liquid gas in the tank or by the cold gas that is evacuated or that escapes at the probe. | 04-18-2013 |
20110099356 | DEVICE FOR CORRECTING SET-POINT SIGNALS AND SYSTEM FOR THE GENERATION OF GRADIENTS COMPRISING SUCH A DEVICE - A device for real-time correction of set-point signals intended to receive at the input set-point signals and to deliver at its output set-point signals that are modified to compensate for defects, negative effects or the like subsequently encountered during the processing and/or the application of the set-point signals. This device ( | 04-28-2011 |
20100213940 | MAGNETIC FIELD GRADIENT GENERATING SYSTEM AND METHOD FOR REDUCING THE NOISE LEVEL IN NMR/MRI EXPERIMENTS - A magnetic field gradient generating system for a NMR system, includes at least one set of gradient coils, preferably arranged according to three axes of a spatial referential system, and a controlled power supplying unit for the gradient coils, the power supplying unit including, for each gradient coil, a converter/amplifier module, the modules being fed with pulse sequences of digital gradient data provided as word streams by an adapted gradient data generator according to a pulse program, each arrangement of a gradient coil and a converter/amplifier module forming a gradient channel. The power supplying unit also includes an automatic blanking system which scans the gradient data words sent to the [converter/amplifier] modules and, according to sensed values, selectively delivers blanking signals to be applied to the modules in order to disable the power stages of their respective amplifiers connected to the gradient coils, when no current is to be fed to the coils. | 08-26-2010 |
