  • Patent number: 10724974
    Abstract: The present invention generally relates to a method of using NMR relaxation rates (R2) of water molecules as an indicator of the extent of aggregation of biopharmaceutical formulations. The biopharmaceutical can be evaluated nondestructively without the vial or container being opened or protective seal compromised (i.e., broken). The method is applicable to all biopharmaceuticals and the water signal obtained by magnetic resonance relaxometry is very strong and sensitive because water is used as the solvent and is present in high (>90%) concentrations in every biopharmaceutical formulation.

  • Patent number: 10703092
    Abstract: A self-advancing cleaner and a method of operating the self-advancing cleaner. In an embodiment, a rotatable member can engage a transport belt, wherein the rotatable member includes a cleaning surface comprising a surface sufficiently rough to collect and take away ink debris from the transport belt. During a cleaning operation the cleaning surface remains stationary while the transport belt moves in a sliding relative motion with respect to the cleaning surface, which allows the ink debris to be collected on the cleaning surface. Once an ink contamination level associated with the ink debris attains a threshold and a set friction exceeds the threshold, the self-advancing cleaner advances.

  • Patent number: 10698058
    Abstract: In a method magnetic resonance apparatus, a pulse sequence is optimized in order to identify a time interval of the pulse sequence during which gradient pulses are modifiable, and subdividing that time interval into two time subintervals wherein, during one of these two time subintervals, no gradient pulse is activated. Such an optimized pulse sequence can be repeated in a number of repetitions, during which magnetic resonance data are acquired, with a contiguous gradient being activated between repetitions, that performs the role of a conventional spoiler occurring directly before an RF excitation the contiguous gradient occurs during a duration that is shorter than a time directly following acquisition of data in one repetition and before excitation in the next repetition.
