Abstract: Изобретение относится к области транспортировки углеводородов по трубопроводам и может быть использовано как на магистральных трубопроводах, так и на трубопроводах малой протяженности. Узел содержит прижимной фланец и опорный фланец. Фланцы образуют сквозное отверстие, совмещенное с отверстием в магистральном трубопроводе. В отверстии, образованном фланцами, установлено седло клапана и державка клапана. На выходе державки установлена форсунка, за которой внутри магистрального трубопровода установлены закрепленный на державке клапан или закрепленный на седле обратный клапан, управляемый форсункой. Державка клапана уплотнена с использованием сальников, кольца прижимного и контргайки. На внешней поверхности державки клапана и внутренней поверхности седла выполнена резьба, обеспечивающая перемещение державки в седле, при этом на конце державки, противоположной расположению клапана, выполнено средство перемещения державки по седлу.

Abstract: FIELD: toxicology.  
     SUBSTANCE: method relates to toxicology and can be used to determine the toxic effects of organic and inorganic chemical compounds that make up the atmospheric air. The method can also be used for environmental assessment of the state of populated areas. The method for determining the toxicity of air by the germination of seeds of higher plants is carried out in several stages: at the first stage, leaves are collected from the same type of woody plants in dry weather on the experimental territory under study and in a conditionally clean zone; at the second stage, one-type water suspensions are prepared from selected leaves of woody plants. After that 100 leaves from the experimental area and 100 leaves from a conditionally clean zone are placed in beakers with distilled water for solution preparation. The volume of each beaker is 1000 ml. The leaves are mixed for 2-3 minutes. Then the plant leaves are taken from beakers with tweezers. At the third stage, sterilized Petri dishes with a diameter of 10 cm are taken for research. After that filter paper is laid on their bottom. An aqueous pulverized suspension from the experimental zone with a volume of 5 ml is poured into one of the Petri dishes, and a 5 ml aqueous pulverized suspension from a conditionally clean zone is poured into the other Petri dish. 50 seeds of plant test biocultures are carefully and evenly placed on filter paper in each Petri dish with tweezers. The Petri dishes are covered with coverslips and placed in a thermostat for germinating seeds. At the fourth stage, the degree of seed germination of test crops is determined by the length of the roots of germinated seeds and then the level of phytoxicity is calculated on the substrate of aqueous pulverized suspensions from the experimental territory according to the formula: T ph  = (Lc av. -Le av.  / Lc av. ) ×100%, where Lc av.  is the average value of the length of the roots of seeds (mm), which grew on the substrate of aqueous pulverized suspensions from a conditionally clean zone, and Le av.  is the average value of the length of the roots of seeds (mm), which grew on the substrate of aqueous pulverized suspensions from the experimental zone. 
     EFFECT: invention is aimed at increasing the efficiency of the method for determining the toxicity of air by the reaction of germination of seeds of higher plants in aqueous pulverized suspensions containing organic and inorganic substances.

Granted: 2021-06-21
Abstract: FIELD: powder metallurgy.  
     SUBSTANCE: invention relates to powder metallurgy, particularly obtaining gold in the form of powder, up to 40 μm in size using the hydrometallurgy method. It can be applied in microelectronics, the production of decorative elements, electrical conductors and resistors. A solution of auric chloride acid is prepared, with the weight percentage of gold at 100-120 g/l. Aqueous solution of sodium sulfate is used as a reducing agent with the concentration of 250 g/l and is mixed with solution gelatin to obtain a combined solution. The reducing agent and the solution of auric chloride acid are mixed by adding the solution of auric chloride acid to the abovementioned combined solution at a speed of 1 l/min while intensely intermixing the resulting mixture of solutions until gelatin coagulates are completely dissolved. The resulting mixture of solutions is heated to 50°C with its subsequent sedimentation during at least 1 hour to ensure gold settles down in the form of powder that is then filtered flushed out and riddled in acetone through a bolter with the screen size of 40 μm. The powder riddled is washed using ethanol, filtered with the minus fraction removed, and dried.  
     EFFECT: invention provides obtaining gold powder of the uniform size of 40 μm and pour density of 1.0-5.0 g/cm 3  along with higher process repeatability and the reduction of gold “waste” in the production process.
