Abstract: A method and device for detection of solid organic matter and fluids in a shale rock by means of low field Nuclear Magnetic Resonance (NMR) in a single measurement, by submitting a rock sample to a 2D NMR assay comprising applying a 2D pulse sequence with a saturation-recovery, or inversion-recovery, in an indirect dimension and an FID-CPMG in a direct dimension. The method can be used as an analytical technique for rock samples from unconventional hydrocarbon reservoirs.

Abstract: A modified surface topography for agricultural tools includes dimples are arranged in a parallelogram (hexagonal) pattern, the morphological unit of which is an equilateral triangle. This surface pattern can be applied to various tools which are impeded by the traction of the soil.

Abstract: A substantial reduction in traction force demand can be achieved for agricultural tools with modified surface topography comprising dimples arranged in a parallelogram (hexagonal) pattern, the morphological unit of which is an equilateral triangle.

Abstract: The present invention is an interposer for electrically coupling a microcard with a mother board. The interposer includes a frame which is interposed between the microcard and the motherboard, electrically connecting the microcard and the motherboard by means of plated via-holes. The substrate is organic and a plurality of chips are mounted on both sides of the substrate. On the opposite sides of the interposer are pluralities of metal pads which are coupled by metallized via holes, the pads in turn connected to the chips, thereby coupling chips or cards on one side of the interposer to chips or boards on the other side. Electrical connection between the chips on the top side of the substrate and the metal pads on the lower side of the substrate is provided by the metallized via holes.

Abstract: In the manufacturing process of electronic modules a problem could arise when the modules have non-flat top surface. This is due to the fact that most of the automatic picking tools uses a vacuum nozzle to pick and place the module. According to the present invention a flat feature (a cap or a stud) is added to the module. This flat feature can be either fixed on the module or removable after the manufacture in order to reduce the dimensions.

Abstract: The method of testing units for the processing of magnetic disks comprises the insertion of a suitably modified disk into the testing unit and the reading of this disk when operations controlled by a testing programme are carried out. The disk for testing is modified and has a plurality of concentric tracks recorded on one or both sides in such a way that the distance between two tracks is slightly greater than the distance between the tracks of standard disks. Only the central track coincides exactly with the corresponding central track of standard disks. After the modified disk has been inserted in the testing unit, the magnetic head is firstly positioned on the central track of the disk and then displaced on the tracks moving increasingly further from the central track.
