Abstract: FIELD: fire-fighting equipment.  
     SUBSTANCE: invention relates to fire-fighting equipment, namely to a lock and release device for a gas fire-extinguishing installation, which stores a fire-extinguishing agent under pressure in a cylinder and releases it upon receipt of a trigger pulse from external triggers. The lock and release device of the gas fire extinguishing installation includes a hollow body with inlet and outlet channels, a shutoff element installed with the possibility of its reciprocating movement and blocking the axial passage in the working control chamber, closed with covers. The shut-off element is made in the form of a cylindrical piston shutter with the possibility of movement in the working control chamber under a control action along an axis located perpendicularly and intersecting the axis of the product supply channel. On the edge of the cylindrical surface of the piston valve from the side of the control channel, a circular groove is made into which an O-ring made of SKF-260V fluorocarbon rubber is installed. A saddle groove is made on the cylindrical surface of the piston valve, around the product feed channel, into which an O-ring made of SKF-260V fluorocarbon rubber is installed. A guide groove is made on the side surface of the cylindrical piston valve, which provides movement relative to the cylindrical pin installed in the hole in the chamber and prevents the shutter from turning in it. Two through holes are made on the lateral cylindrical surface of the working chamber. The spring-loaded ball locks of the shutter go into these holes in the closed and open position. A threaded hole is made in the center of the left screwed-on cover of the device chamber, into which a tube is screwed in, supplying a control action for opening the shutter with a vector coinciding with the axis of movement of the shutter. A threaded hole is made in the center of the right-hand screwed-on cover of the device chamber, into which a plug is screwed in the form of a stopper plug. Such a plug has a structural leakage on the thread and provides the required deceleration of the valve movement due to a gradual decrease in pressure in the damping cavity near the right cover. Likewise, the stopper plug can be turned over and a transport stopper is screwed into this hole with a long part, excluding the possibility of movement of the shutter and opening of the device. 
     EFFECT: simple, fast and reliable lock and release device.

Abstract: FIELD: wastewater treatment.  
     SUBSTANCE: invention can be used in wastewater treatment. The method for regeneration of nitrogen and phosphorus from wastewater by precipitation of their ions in the form of struvite includes precipitation of struvite at the initial molar ratio [Mg 2+ ]:[NH 4   + ]:[РО 4   3- ], close to the stoichiometric composition of struvite. In the presence of fluorine ions in the wastewater, water is pretreated by adding calcium carbonate, precipitation and separation of the calcium fluoride precipitate. The Mg 2+  and РО 4   3-  ions missing for the formation of struvite are introduced into the wastewater as an intermediate product, which is obtained by mixing solutions. In this case, a solution of magnesium chloride or sulfate is mixed in an amount that allows to obtain a molar ratio of Mg 2+ /NH 4   +  from 1.1 to 1.2 in wastewater, and a solution of sodium or potassium phosphates, such as Na 3 PO 4  or K 3 PO 4  and Na 2 HPO 4  or K 2 HPO 4 , in an amount and ratio that allows to set a pH in the wastewater in the range from 8.0 to 9.5 and a molar ratio of РО 4   3- /NH 4   +  equal to 1.0. The resulting solutions are mixed at 25-70°С and intensive stirring for 1-2 minutes to prepare an intermediate product, which is introduced into the wastewater immediately after cooking when it is mixed. The resulting suspension is mixed for 15-20 minutes, the precipitate is settled for 20-30 minutes, the clarified water is separated by decantation.  
     EFFECT: invention makes it possible to increase the degree of extraction of NH 4   +  и РО 4   3-  ions from wastewater while simultaneously precipitating ammonium and phosphate ions in the form of struvite, preventing the appearance of impurities of other phases in the composition of the precipitated product.

Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine, namely to functional diagnostics, and can be used in the diagnosis of breast diseases. For this purpose, an MRI examination is carried out at the first stage, in which a pre-contrast tomography is performed for 2.5-3 minutes with suppression of the signal from adipose tissue to obtain images of the breast. Then, using an automatic injector, a contrast agent is injected in a jet for 5-10 seconds, after which post-contrast tomography is performed, first with images with signal suppression from adipose tissue, then without signal suppression from adipose tissue. At the same time, post-contrast tomography is performed 10-15 seconds faster than pre-contrast. The total time of the study is 3-6 minutes. In case of detection of breast cancer and/or suspicious changes, an ultrasound examination is performed at the second stage. At the third stage, a biopsy is performed under ultrasound control or MR control. When conducting an MRI examination, a high-field magnetic resonance tomograph with a magnetic field strength of 1.5-3 T is used.  
     EFFECT: method provides effective diagnosis of breast diseases with a short time first stage of the study, as well as increasing the productivity of a medical institution during a mass examination, which will save the resources of medical institutions without mammography, which will reduce the radiation load on the patient.

Abstract: An identification card incorporating an integrated circuit (IC) chip for processing electric signals incorporates a separate supporting element for the IC chip. The supporting element is mounted in a window of one corner of the identification card to avoid the principal axis of stress. The chip supporting element and the window are of the same general shape. However, the window is larger than the supporting element to provide a clearance area surrounding the supporting element. Resilient cover sheets are adhesively mounted to the identification card to fix the position of the supporting element within the window and maintain the clearance area surrounding the supporting element. The top cover sheet has a recess which is aligned with a portion of the supporting element to allow access to contacts mounted on that portion of the supporting element to provide electrical connections with the IC chip.

Abstract: The instantaneous angular velocity of a rotating shaft or the like is translated from the relative rotation of a mark carrier, having a scale of marks, and a sensing device. A series of signals are produced and processed in a calibrating run and thereafter in a series of operating runs. In the calibrating run, the time distance of the sensed signals between at least one pair of the marks is measured and from it a calibrating value is calculated corresponding to the absolute angular distance between the marks and thereafter stored. During the operation runs, the instantaneous time distance of the sensed signals between the marks is measured and the instantaneous velocity is obtained by comparing it with the stored calibrating value.
