20120159412 | TRANSISTOR-LEVEL LAYOUT SYNTHESIS - A layout tool partially replicates the layout of a base cell to determine the layout for a target cell. The base cell is information representing an arrangement of a set of transistors having an established layout. The target cell is information indicating the desired arrangement of another set of transistors. The layout tool identifies correspondences between subsets of the base cell transistors and subsets of the target cell transistors and replicates the layout of the identified base cell subsets to determine the layout for the identified target cell subsets. In addition, the layout tool can identify base cell subsets that closely match target cell subsets, but for which the layout cannot be exactly replicated because of obstructions in the target cell subsets. For such identified base cell subsets, the layout tool can determine a layout by adjusting the base cell subset layouts to avoid the obstructions. | 06-21-2012 |

20150369417 | COVERING SPACER FOR PROTECTING THE INTERNAL SURFACE OF A PIPE JOINING ELEMENT - A covering spacer interposed between two facing ends of two pipes connected to each other through a joining element includes: a first annular element with its external surface with constant diameter and a second annular element with its internal surface with constant diameter. The external surface of the second annular element and the internal surface of the first annular element are configured so as to allow them to be coupled with each other through interference. Yielding connection points are suited to maintain the first and the second annular element joined together at the level of their two first ends. The yielding connection points are configured so that they break when the first annular element and the second annular element are thrust against each other through the application of a predefined minimum pressure. | 12-24-2015 |

20110049239 | METHOD FOR STORING AND CODING INFORMATION WITH RAMAN-ACTIVE SUBSTANCES - A method for storing and coding information which utilizes mixtures of metal nanoclusters with dyes and other Raman-active substances is disclosed. A method for reading and decoding the stored information by measuring the Raman spectra is also disclosed. To code and store information, a plurality of dots or markers, each consisting of a mixture of two or more Raman-active substances taken in different proportions, is applied on a on object. The number of substances in the mixture and the relative quantities of each substance in the mixture carry the information to coded by each dot. By scanning a sequence of dots on the object, information stored in the sequence can be read and decrypted. Surface enhanced Raman scattering associated with metal nanoclusters and large Raman cross section of colored Raman-active substances make it more feasible to detect the Raman signal from a single dot of a small size (up to the diffraction limit) on the millisecond time scale. | 03-03-2011 |

20090165585 | Zhuravlev Gear Drive - The inventive gear drive comprises toothed wheels with teeth of toothed crowns interacting with single- or multi-flow elements. Working profiles of the interacting teeth comprise piecewise and/or pointwise conjugate, convex at a tooth point and concave at a tooth root arc-shaped sections continuously connectable to each other or to involute sections. The interacting toothed crowns are so embodied that a phase gap of the face tooth intermating at a discrete angle from a point, where the interaction of profiles ends at a point, where the interaction of the face profiles of the next tooth pair starts. The drive is so embodied that the face tooth overlap ratio thereof is less than 1. The so improved teeth provide for high level of the contact tightness and absence of axial forces at engagement, increase the structural flexibility of the gear drive teeth in order to improve their qualities. | 07-02-2009 |

20090166030 | Method to monitor reservoir fracture development and its geometry - Method to monitor reservoir fracture development and its geometry may find its application at oil and gas fields as well as in coal mining industry. The method provides injection of conductive fracturing fluid into the wellbore under pressure enabling to create a fracture in the formation and penetrate into it. At the stage corresponding to the end of the fracturing fluid charging a series of voltage pulses is applied to the fracturing fluid. In the well parameters of the electromagnetic field and/or acoustic signals resulting from applying the voltage pulses to the fracturing fluid are measured, and the fracture tip coordinates are determined. | 07-02-2009 |
