Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medical equipment, namely to a medical thread insertion device. Medical thread insertion device comprises a medical suture, a needle portion and a tubular portion. Medical suture has an external surface on which thorns are formed. Needle part has a cavity into which the medical thread can be inserted. Needle part includes a needle having the specified length. Tubular part has a cavity in which a needle can be inserted. Tubular portion is inserted into the inner side of the skin and comprises a tube having a length which is shorter than the length of the needle. When the tubular portion into which the needle portion is inserted into which the medical thread is inserted is inserted into the skin tissue, when the needle is inserted into skin tissue, the end portion of the needle can protrude towards the outer side of the tube owing to the tube length difference and the needle. 
     EFFECT: use of the invention enables to minimize skin tissue damage when the medical suture is introduced into the skin, and also does not cause any side effects, even when the insertion instrument is removed from the skin, when the position of the area to be treated is to be changed.

Abstract: Использование: в области электротехники. Технический результат – обеспечение автоматической синхронизации и восстановление нормального режима параллельной работы разделившихся частей электрической сети с включенными в сеть работающими генераторами на удаленных коммутационных аппаратах. Способ заключается в балансировании послеаварийных режимов в отделившихся частях сети средствами противоаварийного ограничения недопустимых отклонений частоты и напряжения. Измеряют разности частот, модули и фазы векторов напряжений с двух сторон коммутационных аппаратов, соединяющих синхронизируемые части электрической сети. При выполнении условий допустимости этих разностей включают коммутационные аппараты. После синхронизации переходят от регулирования частоты и напряжения на генераторах к регулированию перетока по сечению. Согласно способу на генераторах разделенных частей сети создают согласованное линейное периодическое низкочастотное изменение напряжения и частоты с разной для каждой отделившейся части частотой. После включения коммутационных аппаратов по факту снижения зависимости изменений частоты от изменений выдаваемой генераторами мощности фиксируют переход на параллельную работу частей сети. Прекращают периодическое низкочастотное изменение мощности и напряжения генератора. 2 ил.

Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine and can be used in clinical physiology, physical culture and sports, endocrinology and other fields of medicine. Based on gender, age, height (H) and body weight (BW) of a person the following is calculated: the body volume index (I v ), the proper volume of circulating blood (PVCB), the proper basic metabolism for the daily time interval (PDM), the proper minute basic metabolism (PMBM = PBM/1440). During the fixed time, exhaled air is collected into an airtight Douglas bag and the minute volume of respiration (MVR) is determined, in which the volume of oxygen absorbed when passing through the lungs of 100 ml of air, or the percentage of oxygen absorbed (POA), is determined, and the minute volume of oxygen absorption (MVOA) is calculated: MVOA=MVR⋅POA/100. The minute exchange (ME) is calculated using two formulas: ME(1)=MVOA⋅CEO, ME(2)= PMBM⋅MVR/ PVCB/RC, where CEO is the caloric equivalent of oxygen, and RC is the respiratory coefficient. The corresponding values of RC and CEO are selected from the table: the values of the caloric equivalent of oxygen at different RC. The value of a person’s minute exchange is considered real when the values of the formulas ME(1) and ME(2) coincide, if the values of the formulas ME(1) and ME(2) do not coincide, then to determine the real minute exchange, step-by-step shifts of the values of RC and CEO are carried out according to the table until the values of the formulas coincide.  
     EFFECT: method provides an increase in the reliability of the determination of human minute exchange due to the use of physically and physiologically sound formulas in calculations.

Abstract: Изобретение относится к цветной металлургии, а именно к подготовке карналлитового сырья к электролизу обезвоживанием в печи кипящего слоя и переработке пылевых отходов. Подготовка карналлита включает его подачу в трехкамерную печь кипящего слоя, последовательное передвижение его через ряд горизонтально расположенных камер печи при одновременной обработке топочными газами, обезвоживание. Отвод отходящих газов через газоход и очистку отходящих газов от образующейся карналлитовой пыли осуществляют в циклонах с последующим ее возвратом в следующую по ходу движения материала камеру печи. Отходящие газы третьей камеры печи кипящего слоя дополнительно очищают от карналлитовой пыли в рукавном фильтре. При этом поддерживают вакуумметрическое давление под сводом третьей камеры печи кипящего слоя равным 0,01-0,09 кПа. Перепад вакуумметрического давления в рукавном фильтре не более 2 кПа. Температура отходящих газов в газоходе на выходе из третьей камеры печи кипящего слоя не выше 260°С. Уловленную карналлитовую пыль в рукавном фильтре извлекают для дальнейшего использования в качестве сырья для электролитического получения магния и хлора. Способ позволяет повысить степень очистки газов и улавливания карналлитовой пыли до 99,0-99,5%, снизить потери обезвоженного карналлита с пылью при экономии сырья, полученного от поставщика, за счет расширения сырьевой базы. 2 пр.
