20100115913 | GAS TURBINE PLANT - The invention relates to gas turbine plants which can be used for gas turbine locomotives and mobile and stationary power plants and which use cryogenic gas fuel. The oil systems of a gas turbine engine and of actuating units are designed in the form of individual adjustable flow circuits each of which comprises fuel-oil heat exchangers, the cooling medium of which his in the form of a cryogenic gas fuel, a delivery pump and an oil tank. The cooling cavities of the fuel/oil heat exchangers are connected, at the inputs thereof, to a fuel supply and adjusting device and to a fuel heater, which is arranged, at the outputs thereof, in the sleeve of the gas turbine engine. Said invention makes it possible to design a low-consumption gas turbine plant provided with a small-sized oil-cooling and fuel-heating system. The invention makes it possible to recover the heat removed by oil from lubricated friction units of the gas turbine engine and the actuating units driven thereby and to return said heat to the thermodynamic circuit of the gas turbine engine. In addition, the power consumption for needs of the gas turbine plant is reduced, the structural design for the oil cooling system is substantially simplified and the fuel heater can be of small size due to the fact that a cryogenic gas is heated in the fuel/oil heat exchangers. | 05-13-2010 |

20150021522 | METHOD AND DEVICE FOR PRODUCING A KRYPTON/XENON MIXTURE - The invention relates to inert gas production processes and can be used for producing a krypton/xenon mixture from a stream of oxygen recovered from air separation plants and containing 0.05-0.5% krypton and xenon. The method for producing a krypton/xenon mixture involves purifying a stream of gaseous primary concentrate by the catalytic combustion thereof and subsequently cooling same, purifying the primary concentrate of catalytic combustion products, carrying out cooling upon completion of purification, fractionating the primary concentrate in a rectification column to form a stream of krypton/xenon mixture and a stream of stripped oxygen and removing the stream of krypton/xenon mixture from the rectification column in the form of a target product, as well as purifying the krypton/xenon mixture of radon. The invention makes it possible to extend the scope of use of the krypton/xenon mixture. | 01-22-2015 |

20110223674 | ANALYTICAL INSTRUMENT - An ion mobility spectrometer analytical instrument, including an ion mobility spectrometer, a swab interface, and a desorber assembly. The desorber assembly includes a heat transfer device configured to heat a desorber, as well as a supply configured to direct gas through the desorber. The instrument further includes a drift tube, high voltage device arrayed, at least in part, proximate to the drift tube, wherein the high voltage device is configured to change a polarity of a voltage applied to the drift tube and have an absolute voltage of about 500 to 1500 volts. The instrument further includes a reactant supply unit adapted to supply reactant during a sample substance analysis, and a control unit. | 09-15-2011 |
20140264021 | ION MOBILITY SPECTROMETRY (IMS) DEVICE WITH CHARGED MATERIAL TRANSPORTATION CHAMBER - An ion detection assembly is described that includes a drift chamber, an inlet assembly, and a collector assembly. The drift chamber is formed of substantially non-conductive material and/or semi-conductive material. A patterned resistive trace is deposited on one or more of an interior surface or an exterior surface of the drift chamber. The patterned resistive trace is configured to connect to a source of electrical energy. The inlet assembly and the collector assembly are in fluid communication with the drift chamber. The inlet assembly includes an inlet for receiving a sample, a reaction region for ionizing the sample, and a gate for controlling entrance of the ionized sample to the drift chamber. The collector assembly includes a collector plate for collecting the ionized sample after the ionized sample passes through the drift chamber. | 09-18-2014 |

20140246581 | LOOPED IONIZATION SOURCE - Looped ionization sources for ion mobility spectrometers are described. The ionization sources can be used to ionize molecules from a sample of interest in order to identify the molecules based on the ions. In an implementation, an electrical ionization source includes a wire that is looped between electrical contacts. The wire is used to form a corona responsive to application of voltage between the wire and the walls of an ionization chamber. The corona can form when a sufficient voltage is applied between the wire and the walls. A difference in electrical potential between the wire and a wall forming an ionization chamber, in which wire is contained, can be used to draw the ions away from the wire. In embodiments, the wire can be heated to reduce the voltage used to strike the corona. The ions, subsequently, may ionize the molecules from the sample of interest. The looped corona source can also be used in mass spectrometers (MS). | 09-04-2014 |
