Aleksandr Valentinovich Bolshakov, St. Petersburg RU
| Patent application number | Description | Published |
|---|---|---|
| 20080210595 | Light Oil Fuel - The invention relates to oil refining, more particularly to a composition of a light fuel oil for use in medium-speed diesel engines of marine power units. The inventive light fuel oil comprises, in % by wt.: black oil—(4-10), tar—(2-10), light catalytic cracking gas oil—(10-30), heavy catalytic cracking gas oil—(5-10), a straight-run diesel fuel—(8-10), a viscosity breaking residuum of a heavy oil fraction—the rest. The selected component ratio will enable to improve the fuel stability in transportation and storage, expand the range of available fuels and increase the production volumes of quality fuels, while rationally using poor-quality products readily available at refineries. | 09-04-2008 |

| 20090231954 | Micro-Annulus Detection Using Lamb Waves - A method, apparatus and computer-readable medium for identifying a micro-annulus outside a casing in a cemented wellbore. The attenuation of a Lamb wave and a compressional wave is used to determine a presence of a micro-annulus between the casing and the cement. | 09-17-2009 |
| 20100097887 | Active Noise Cancellation Through the Use of Magnetic Coupling - Passive suppression of casing signals is used to improve the ability to measure formation velocities. Passive suppression includes the use of a magnet slidably coupled to the casing. | 04-22-2010 |
| 20100263449 | Casing Thickness Evaluation Method - Evaluating casing thickness by inducing SH0 and SH1 modes of a shear wave in the casing. The SH0 group velocity and SH1 mode group velocity (Vg) are measured and the measured SH0 mode group velocity is assigned as the tubular material shear velocity (Vs). A shear wave wavelength λ from the ratio of SH0 mode frequency (f | 10-21-2010 |

| 20110207349 | Tethered Port Protector for Portable Electronic Devices and Kit of Port Protectors - A port protector for an electronic device that is formed with one or more ports having an access opening. The port protector includes a protective plug having a shape substantially corresponding to a shape of the access opening of the port of the electronic device and being configured to seal the opening of the port when the plug is inserted into the opening. An elastic tether strip has a first end connected to and integrally formed with at least a part of the protective plug. An attachment tab is integrally formed at a second end of said tether strip, opposite and distally from the protective plug. The attachment tab is configured for removable attachment to the surface of the shell body of the electronic device. The tether strip has a length enabling the protective plug to be inserted into and removed from the opening of the port while the attachment tab is attached to the surface of the shell body of the electronic device. | 08-25-2011 |
