20100139984 | ROTARY DRIVE FOR APPLYING ROTARY TORQUE TO A SHAFT TO BE AXIALLY VIBRATED - A drive assembly suitable for a spindle connection to a drill string or other shaft, the assembly comprising or including a drive shaft, a shuttle rotatable under the action of the drive shaft but being slidable relative thereto, the shuttle carrying magnets, a containment assembly to constrain the shuttle to a shuttle axis, the containment assembly carrying magnets to co-act with those of the shuttle as the shuttle is rotated by the drive shaft thereby to cause the shuttling of the shuttle, a spindle not forming part of the shuttle arrangement to receive vibration from said containment assembly and/or said shuttle (e.g.; through a cushion of liquid), a carriage assembly on part of the spindle slidable on an axis coincident with and/or parallel to the spindle's rotational axis, and a drive carried by the carriage assembly to rotate the spindle or to rotate both the spindle and part of the carriage assembly. | 06-10-2010 |
20100282514 | Vibrational apparatus - Vibrational apparatus capable of providing a vibrational output, said apparatus comprising or including an assembly having a shuttle capable of shuttling between complementary structures, at least one of which complementary structures provides the vibrational output, | 11-11-2010 |
20110203395 | VIBRATIONAL APPARATUS - Vibrational apparatus capable of providing a vibrational output, said apparatus comprising or including an assembly having a shuttle capable of shuttling between complementary structures, at least one of which complementary structures provides the vibrational output, | 08-25-2011 |
20110260815 | VIBRATIONAL APPARATUS - Vibrational apparatus capable of providing a vibrational output, said apparatus comprising or including an assembly having a shuttle capable of shuttling between complementary structures, at least one of which complementary structures provides the vibrational output, | 10-27-2011 |

20130289887 | Method for Characterizing a Sample by Data Analysis - The invention relates to a method for characterizing a sample, having the following steps: providing at least one analysis result having a plurality of values, wherein the analysis result was generated by the analysis of a sample by at least one analysis method; determining the value of at least one mathematic relation between at least two values of the plurality of values; generating a characterizing signature of the sample on the basis of the value of the at least one mathematic relation. The invention further relates to a method for characterizing a system in which method the preceding method is used. | 10-31-2013 |
20150042328 | Method for Substance Identification From NMR Spectrum - The present invention relates to a method which allows for an automatic substance identification on the basis of an NMR spectrum. In the scope of the method, determining a multitude of integral ratio values, in each case from at least two integral values of the NMR spectrum, takes place, wherein each integral ratio value specifies the ratio of the height and/or area of the underlying spectral values, and determining a multitude of distance values, in each case from at least two position values of the NMR spectrum, takes place, wherein each distance value specifies the spectral distance between the underlying spectral values. The integral ratio values and the distance values are then used for substance identification. | 02-12-2015 |
