Abstract: FIELD: construction.SUBSTANCE: invention relates to construction, namely to devices for locking hatches of wells and chambers installed on aboveground and underground networks and structures, to prevent the random and unauthorized opening or dismantling of the hatch cover and the well hatch. A method for locking the hatch of a well installed on aboveground and underground networks and structures, in which the mounting of the hatch cover is carried out under the overlap plate of the well neck. At the same time, rigid fixation of the cover is provided by fixing its holding levers under the overlap plate, which eliminates random opening of the cover and their offset relatively plate. The plug that covers the key hole ensures that water and dirt are removed from the locking mechanisms. First, the plug is removed from the restraint cup, which, by means of fasteners in the upper part, is fixed, to the hatch cover, and at the bottom, by means of retaining nut, locks restraint cup and threaded guide pin among each other. After that, by rotating the key, the threaded guide pin is set in motion, which at the same time ensures the upward movement of the threaded crosspiece, driving the push levers, which in turn begin to move up the guide plate and push the holding levers, changing their position until they occupy the extreme position of fixation, depending on the shape of the well neck. In the lower part, the guide plate is fixed with a coupling crosspiece, ensuring its vertical movement by means of a threaded coupling made in the form of a sliding bearing.EFFECT: increased reliability of locking the hatch and preventing unauthorized opening of the hatch, as well as penetration into the shaft of the well (chamber) when used on structures of any purpose and of various geometric shapes.1 cl, 2 dwg

Granted: 2021-01-21
Abstract: Изобретение относится к радиотехнике. Технический результат - повышение точности оценки фаз многочастотных периодических сигналов в условиях наличия помех. Это достигается тем, что для исходного сигнала, заданного отсчетами мгновенных значений в моменты времени для последовательности частот сигналов, определяют сигнал - результат умножения входного сигнала на синус опорной частоты. Значения опорных частот устанавливают равными значениям частот входного многочастотного сигнала. Каждый опорный синусоидальный сигнал многократно сдвигают по дискретным значениям фаз. Обработку сигналов, которые образуются после умножения входного сигнала на опорные сигналы, осуществляют одинаково в соответствующих линейках - каждый из сигналов разветвляют на две одинаковые составляющие. Первую составляющую фильтруют фильтром нижних частот (ФНЧ), одновременно вторую составляющую фильтруют полосовым фильтром (ПФ). Выбор фильтров осуществляют с идентичными в максимальной степени фазочастотными и амплитудно-частотными характеристиками. Формируют отсчеты сигналов и находят суммы отсчетов сигналов. Рассчитывают значения разностей полученных сумм. Запоминают значения фаз. 2 ил., 1 табл.

Title: Method for controlling sealing capacity and detecting leak point in pipeline with shut-off element

Abstract: FIELD: diagnostics. 
     SUBSTANCE: invention relates to the field of technical diagnostics, in particular, to methods for controlling the sealing capacity of pipelines, and can be used to assess the sealing capacity of pipelines and detect leak points in pipelines of nuclear power plants. The method for controlling the sealing capacity and detecting a leak point in a pipeline with a shut-off element consists in recording acoustic signals at two points along the length of the pipeline and subsequently processing the received acoustic signals. Acoustic signals are recorded in the wide ultrasonic range at two points along the length of the pipeline, located on the pipeline before and after the shut-off element. The recorded ultrasonic signals are processed by an analog-to-digital converter and two signal spectra corresponding to the record points are constructed based on the obtained values using the Fourier transform. A range from 15,000 to 90,000 Hz is selected in the constructed signal spectra, and the highest amplitude value is selected in this range in both signal spectra. The amplitudes of the signal spectra are then divided in the specified frequency range by the largest amplitude value, and the difference between the signal spectra before and after the shut-off element is determined by the proposed formula. Based on the determined values, a conclusion is made on the absence of leaks if the difference S between the signal spectra is less than -100 or the presence of an insignificant leak if the difference between the signal spectra is in the range from -100 to 100. The conclusion about a significant leak is made when the difference between the signal spectra is greater than 100. It is also proposed to record ultrasonic signals using acoustic emission sensors. 
     EFFECT: reducing the duration of conducting the diagnostic examination and eliminating the influence of the pipeline geometry on the result obtained during the diagnostic examination.

Abstract: Disclosed is a system for synthesizing emphasis-controlled speech from stored signals representative of words precoded by a phase vocoder having analysis bands which are wide relative to the voice harmonic frequency spacings. The stored signals comprise short-time Fourier transform parameters which describe the magnitude and the phase derivative of the short-time speech spectrum. Speech emphasis-controlled synthesis is achieved by extracting the stored signals of chosen words under control of a pitch-duration signal, by concatenating the extracted signals, by modifying the magnitude parameters of the extracted signals to effect a desired speech intensity, by interpolating the extracted parameters, and by decoding the resultant signals in accordance with phase vocoder techniques.
