Motion control of intratubal objects in gas pipelines using the vibrometer

Describes the principle of operation and the results of the test layout vibrometer that allows the posting on the outer surface of the pipeline to determine in real time to within a few meters of the location and speed of intratubal objects at distances of over 25 km. A comparative analysis of the amplitude-frequency characteristics of elastic waves recorded by the accelerometer on the surface of the security valve of the gas pipeline with a diameter of 720 mm when driving in a gas cleaning pigs, shell-pattern and navigation caliper.

Keywords: accelerometer, frequency spectrum, gas pipeline, intratubal object, speed, vibration, weld tabs.

Magnetometers and gradiometers for scientific researches

At Pushkov Institute of terrestrial magnetism, ionosphere and radio wave propagation of the Russian Academy of Sciences (IZMIRAN) together with other organizations throughout last decade a number magnetometric devices for a gradient magnetic field measurement both in movement, and in a statics, in field conditions and for carrying out of researches in observatories is created. These devices have been made on the basis of quartz, proton and fluxgate magnetometrical converters. All created magnetometers and gradiometers have passed metrological checking and tests in magnetic observatory of IZMIRAN (an observatory Moscow) and were used on the various scientific expeditions organized as in Russia, and abroad.

Keywords: magnetic observatory, magnetometers, magnetometrical devices, gradiometers, magnetometrical converters, proton magnetometer, fluxgate magnetometer, magnetic field sensors, magnetic measurements, gradient magnetic field measurement in movement.

Electrostatic micro actuator

This paper describes the original constructive version electrostatic minimanipulators. The combined effect of the mechanical and electrical forces overcomes the resistance to reactance induced charges, sealing contacts, inertia and ensures immediate return to the starting position of the armature. Electrostatic minimanipulator can be used in systems: control, switching, communication, adjustment.

Keywords: MEMS, electrostatic, micromechanic, minimanipulator, design.

Information-measuring and operating system of definition of teplofizichesky properties metal with use of spectral methods

It is shown that now accuracy and speed of reception, processing and reproduction of results, that is reception of exact indicators is necessary for definition improvement of quality termal properties metal melts in a mode of real time.
It is defined that such results are reached at the expense of application of the modern information-measuring and operating systems, allowing to carry out more and more fast and effective control of the processes proceeding in steel-smelting units, and also processes of processing of a steel in units of extraoven processing.
New methods and technical decisions of definition termal properties metal melts with use of spectral methods are offered in the contactless way.

Keywords: improvement of quality, information-measuring and operating systems, termal properties, a contactless way, metal melt, spectral methods.
