Abstract: Изобретение относится к области медицины и предназначено для индивидуальной защиты верхних дыхательных путей от воздушно-капельной инфекции, а также предотвращения распространения такой инфекции от пользователя в окружающую среду, и в основном может быть использовано при общении с лицами с дефектами слуха, способными воспринимать речевую информацию по артикуляционным движениям губ, например преподавателем или любым пользователем маски, желающим довести такую информацию до обладающих такой способностью лиц с дефектами слуха. Индивидуальная защитная маска содержит лицевую часть, устанавливаемую на средство крепления на голове пользователя, представляющее собой оголовье. При этом конструкция индивидуальной защитной маски включает в себя микрофон, видеокамеру, располагающиеся непосредственно в области предполагаемого местонахождения губ пользователя, элемент подсветки области губ пользователя и датчик освещенности. При этом конструкция маски содержит дисплей, динамик, электронный преобразователь, на который подается сигнал с микрофона, видеокамеры и датчика освещенности, радиомодуль передачи данных, сигнал с которого транслируется на приемное устройство сигнала и источник питания, установленные на оголовье. В верхней и нижней части установлены элементы для обеззараживания воздуха УФ-излучением. В некоторых вариантах исполнения микрофон представляет собой закрепленный на оголовье микрофон, выполненный на кронштейне, и располагающийся непосредственно в области предполагаемого местонахождения губ пользователя. В некоторых вариантах исполнения в качестве микрофона используется ларингофон. При этом элемент для обеззараживания воздуха УФ-излучением может содержать корпус с входным и выходным окном, внутри которого установлен вентилятор, УФ-светодиоды и фильтр типа НЕРА высоких классов. При этом в качестве приемного устройства сигнала, транслируемого с радиомодуля передачи данных, установленного в индивидуальной защитной маске, может выступать внешняя акустическая система, мобильное устройство или слуховой аппарат с имеющимся беспроводным радиомодулем. При этом в некоторых вариантах исполнения лицевая часть маски представляет собой лицевую часть, выполненную из прозрачного материала и закрывающую лицо целиком. Технический результат - расширение функциональных возможностей индивидуальной защитной маски за счет обеспечения отчетливого восприятия речи от пользователя, на которого надета индивидуальная защитная маска, окружающими его людьми за счет возможности визуализации артикуляции губ пользователя, а также за счет обеззараживания воздуха, поступающего в пространство между лицевой частью индивидуальной защитной маски и лицом пользователя. 5 з.п. ф-лы, 2 ил.

Abstract: FIELD: measuring technology and electronic instrumentation. 
     SUBSTANCE: invention relates to measuring technology and electronic instrumentation and can be used in flow metering of conductive liquids, such as water and aqueous solutions of salts, alkalis and acids, conductive organic and inorganic chemical compounds. The converter of a conductive liquid flow rate consists of a housing made of a dielectric and electrodes installed flush with its inner surface, and differs in that the housing contains two rows of electrodes located in the same plane opposite each other, in each of which the number of electrodes is determined by the required number bits of the output binary code, the electronic part includes a set of resistors, a stable reference current source, a resistive voltage divider, a set of comparators and a positional binary code to natural binary code converter, wherein, the electrodes of one of the two rows are connected to the positive terminal of the reference current source, the electrodes of the other row are connected through the resistors of a set of resistors to the negative terminal of the same reference current source so that currents redistributed between the electrodes, the sum of which is always equal to the reference current, create voltage drops across the resistors in order of the positional code, then they were normalized in size by a set of comparators, the non-inverting and inverting inputs of which are connected to the resistors of the set of resistors and the resistive voltage divider, respectively. 
     EFFECT: invention improves the conversion accuracy by reducing the number of sources of instability of the function of converting the flow rate of the liquid into the output signal.

Abstract: FIELD: shipbuilding. 
     SUBSTANCE: invention relates to the installation of heavy units in the crowded conditions of the ship's premises. Proposed is a method for non-fitting installation of the unit inside the ship's premises on a pre-assembled foundation using shims, tight-fitting bolts with washers and nuts, and a polymer material, taking into account the amount of shrinkage of the latter. Before loading the unit on the foundation, markings are made relative to the bases of the room and through holes are made in a clean size for fastening the unit with fit for tight-fitting bolts. Then, in the places of through holes, by means of measurements, the required values of the thickness of the linings are determined for installing the unit on the foundation, ensuring the parallelism of the supporting surface of the unit to the main plane of the ship. Shims are made with previously defined thicknesses and through holes of increased diameter for free passage of tight-fitting bolts. The shims are set on the foundation with the alignment of the position of their supporting surfaces relative to the bases of the ship room. Marking is carried out on the shelves of the unit relative to its base planes. Through holes are made in pure size for tight-fitting bolts with a diameter increased by the calculated value of the maximum total marking error. The unit is loaded into the ship's room and placed on the foundation using shims. Reconciliation is carried out using the squeezing devices of the base planes of the unit relative to the bases of the ship's room and secured with tight-fitting bolts with washers and nuts. The gaps between the tight-fitting bolts and the walls of the through holes in the unit shelves and linings are filled with a polymer material. 
     EFFECT: possibility of non-fitting assembly of the unit in the cramped conditions of the ship premises, elimination of non-spillage of polymer material and improvement of the maintainability of the unit mounting structure.

Granted: 1985-06-13
Abstract: An incremental path measuring instrument is disclosed which includes a plurality of reference marks R1 . . . Rn which are interposed between respective code marks C1 . . . Cn. The reference marks and code marks are applied alternately and serially to the reference track included on the measuring scale. A scanning unit is included in the measuring device for scanning in series the reference marks and the code marks. Each of the code marks is unique, and only one of the two adjacent code marks and the respective reference mark must be scanned by the scanning unit in order to identify the reference mark unambiguously. When absolute position values are allocated to respective individual reference marks, the incremental path measuring device can operate in a quasi-absolute mode of operation, since then the position of each of the reference marks is established with respect to a predetermined zero point. Preferably, the code marks each contain beginning of block and end of block symbols in addition to the identifying information needed to identify the respective reference marks. The disclosed path measuring device includes an evaluation circuit which includes a circuit which automatically adapts the trigger threshold required for signal evaluation to the actual amplitudes of the signals.
