20120119489 | TIGHTLY THREADED JOINT FOR OIL FIELD PIPES - The invention relates to building and operating vertical, controlled, directional and horizontal holes of oil and gas fields with difficult operating conditions, and can be used for process casing pipes. The inventive tightly threaded joint for oil field pipes comprises male and female pipes with a conical thread and stop and sealing surfaces. The stop surfaces are brought into contact by the end surface of the male pipe and the mating end surface of the female pipe. The conical thread configuration has a negative angle along a bearing face. The height of thread of the male pipe is less than the height of thread of the female pipe. The end surfaces are designed so that the area thereof is equal to or greater than 60% of the pipe body. The invention makes it possible to increase the operational reliability and effectiveness of the tight joint and to minimize ecological risks. | 05-17-2012 |
20150008667 | TIGHTLY THREADED JOINT FOR OIL FIELD PIPES - A threaded joint for oil field pipes includes a male pipe having a male thread and a female pipe having a female thread. The male thread and the female thread engage along a thread profile, the male pipe with a first end face and the female pipe with a second end face. The male pipe also has as first sealing surface and the female pipe has a second sealing surface. The first end face and second end face are substantially perpendicular to the first sealing surface and second sealing surface. When the male pipe and female pipe are fully adjoined, the first sealing surface abuts the second sealing surface, the first end face abuts the second end face, and the trailing face abuts female thread, while leaving a space between the female thread and the top face, and leaving a space between the female thread and the leading face. | 01-08-2015 |

20150191839 | DEVICE FOR THE DOSED FEEDING OF RAW MATERIAL INTO AN ALUMINIUM REDUCTION CELL - The invention relates to a device for the metered feeding of stock into an aluminium electrolyser. The device comprises a hopper for the material to be metered, a metering chamber with a rod having a pneumatic drive, an upper shut-off element which is rigidly fixed on the rod in the upper part of the metering chamber and is in the form of a valve, a lower shut-off element which is fixed on the end of the rod and is in the form of a cone valve with a conical cover, and charging apertures which are arranged around the perimeter in the upper part of the dosing chamber above the base of the hopper. The upper limits of the charging apertures are arranged above the upper position of the valve, and the distance from the base of the cone valve to the lower section of the metering chamber in an upper position of the rod is not less than the distance from the lower surface of the upper shut-off element to the lower limit of the charging apertures. An increase in the reliability of the device and in the metering accuracy is ensured, and, accordingly, the technological characteristics of the operation of the electrolyser are improved. | 07-09-2015 |

20090052852 | Holey fiber taper with selective transmission for fiber optic sensors and method for manufacturing the same - Large-mode-area single material holey fiber tapers with collapsed by nonadiabatic process air holes in the waist for fiber optic sensors and a method for manufacturing these tapers are claimed. The gradual collapsing of the holes is achieved by tapering the fibers with a “slow-and-hot” method. This nonadiabatic process makes the fundamental mode of the holey fiber to couple to multiple modes of the solid taper waist. Owing to the beating between the modes, the transmission spectra of the tapered single material holey fibers exhibit several interference peaks. That means the all-fiber Mach-Zehnder type interferometer is formed in a holey fiber such a way. The multiple peaks, combined with a fitting algorithm, allow high-accuracy refractometric measurements, temperature-independent strain measurements, measurements of high temperature and may be used for measuring many others parameters. | 02-26-2009 |

20130294896 | METHOD AND SYSTEM OF INCREASING WEAR RESISTANCE OF A PART OF A ROTATING MECHANISM EXPOSED TO FLUID FLOW THERETHROUGH - A method of increasing wear resistance of one or more part(s) of a rotating mechanism includes manufacturing the one or more part(s) with a portion thereof configured to be exposed to wear during fluid flow associated with the rotating mechanism having a dimension different from that of a desired dimension, applying a protective coating of an aluminum bronze alloy to the portion through welding deposition, and mechanically treating the protective coating. The method also includes applying one or more layer(s) of solid-alloy over the protective coating through electro-erosion deposition, and continuing the mechanical treatment of the protective coating and/or the one or more layer(s) of solid-alloy after the solid-alloy deposition to obtain the desired dimension of the portion. | 11-07-2013 |

20130167441 | METHOD FOR THE PSEUDO-DETONATED GASIFICATION OF COAL SLURRY IN A COMBINED CYCLE - The invention relates to the field of power engineering and, more specifically, to systems for generating electricity based on the use of solid fuel, primarily brown and black coal. In the coal gasification method, a gasifier is fed with a uniform activated coal water fuel, the droplets of which are of equal size and the coal particles in said droplets having a similar granulometric composition. The fuel droplets are introduced intermittently in separate doses of fuel with a certain amount of motion being imparted thereto. The milling of the coal for the activated coal water fuel preparation method is adjusted adaptively according to the criterion of the actual amount of volatile substances given off by the coal, and the coal is thoroughly classified according to its granulometric composition. The invention provides for more extensive recovery of thermal energy from coal and more efficient electricity generation. | 07-04-2013 |

20110156707 | METHOD OF STUDYING ROCK MASS PROPERTIES AND APPARATUS FOR THE IMPLEMENTATION THEREOF - The rock mass thermal excitation is performed by means of pumping the flush fluid through the wellbore using a tubing string, the flush fluid temperature differs from the rock mass temperature. Before the thermal excitation, during the thermal excitation and after the termination thereof differential electrical signals proportional to the well bore temperature difference are registered by at least one pair of the temperature transducers positioned along the wellbore axis. The distances between the transducers in the pairs and the number of pairs is selected in advance based on the required accuracy of the determination of the rock mass areas with different properties, minimum and maximum possible length of the rock mass areas identified and the nature and degree of the wellbore temperature noise. Differential electrical signals of the temperature transducers measured before the rock mass excitation start are compared with the differential electrical signals from the same temperature transducers measured during the thermal excitation and the differential electrical signals of different temperature transducers positioned along the wellbore are compared with one another. Based on the comparison results of the differential electrical signals the difference of different rock mass areas are characterized by their properties and the boundaries between the rock mass areas with different properties are identified. | 06-30-2011 |
