Granted: 2003-05-10
Abstract: FIELD: mechanical engineering. SUBSTANCE: in proposed planetary roller-screw drives torque from rotating screw is transformed into axial force through threaded rollers on translationally moving nut. Force is transmitted through multiple places of contact between mated turns of thread of nut and rollers and rollers and screw. Thread of parts of planetary roller-screw drive is modified, with profile of turns consisting of two sections of straight line with real working depth of profile H 1 . Such thread is easy to made and simple for checking. Turns of thread feature higher flexural strength as compared with parts having shaped profile of turns. When turns of modified thread interact, contact strength and rigidity are greater than those in place of similar contact of parts of conventional planetary roller-screw drives and, consequently, load capacity of modified thread drive is greater. When cutting modified thread with different values of H 1 , drives with any required rigidly can be easily made. EFFECT: enlarged operating capabilities. 4 dwg

Abstract: FIELD: waste water treatment. SUBSTANCE: multicomponent waste waters are subjected to sorption-mediated treatment to remove harmful impurities, such as cadmium, nickel, petroleum derivatives, anionic surfactants in dissolved and dispersed forms, in presence of ethylene glycol, polyvinyl alcohol, and mineral salts for use in mechanical engineering and chemical industry, in particular when manufacturing chemical power sources. Preliminarily, waste water is cleaned by two-step flocculation by adding 0.5- 2.2% (of the weight of solids) of cationic polyelectrolyte and removing in series suspended impurities (first step) and dissolved impurities. Subsequent sorption involves such sorbents as successively disposed thermally modified dolomite and activated carbon. Cationic polyelectrolyte, in particular, is copolymer of dimethylaminoethyl methacrylate dimethyl sulfate salt and acrylamide containing at least 80 mol % cationic groups, each concentration in the first state being 0.8- 2.2% and, in the second step, 0.5-1.5% based on the weight of solids. Sorption operation is accomplished by passing waste water through sorbents at velocity 0.5 to 1 cu.dm/min, volume ratio of thermomodified dolomite to activated carbon being 4:1. EFFECT: improved cleaning quality and therefore created closed water supply circuit. 3 cl, 1 dwg, 1 tbl

Abstract: Изобретение относится к технологии машиностроения, к способам формообразования наружных резьб пластическим деформированием, в частности к накатыванию наружных резьб средних и крупных размеров в заготовках из высокопластичных материалов. Задача изобретения – обеспечение возможности накатывания прямоугольных, трапецеидальных и других резьб, повышение производительности и качества обработки резьбовых поверхностей. Способ осуществляется пластическим деформированием металла в роликовой матрице, причем резьбовой профиль деформируют принудительно вращающимися резьбовыми роликами в количестве не менее трех с жесткой кинематической связью между ними. Ролики имеют многозаходную резьбу с профилем, соответствующим профилю накатываемой резьбы, а заготовку, свободно вращающуюся за счет сил трения благодаря вращению роликов, деформируют с торцов, воздействуя двумя пуансонами навстречу друг другу, один из которых является плавающим упором, позволяющим компенсировать осевое перемещение заготовки. Диаметр резьбонакатных роликов подбирается таким образом, чтобы ролики сообщали заготовке осевое перемещение только в направлении плавающего упора, и регламентируется математической зависимостью. Способ позволяет накатывать относительно короткие резьбы стабильных размеров с отношением длины к диаметру не более 5, которые сложно получить другими способами, например прямоугольные и крупные трапецеидальные. 2 ил.

Abstract: FIELD: alternative fuels. 
     SUBSTANCE: invention relates to production of demineralized water-coal fuel used for combustion on heat-and-power plants, mainly in coal or gas-mazut boilers. Process comprises crushing original coal to fineness class -D corresponding to maximum size of joints between organic portion of coal and mineral inclusions. Classification of crushed coal is performed according to fineness classes +D, -D, +d, and -d. Class -d coal is conveyed into classifier, class +D coal to re-crushing, and class -D and +D coals are saturated with water to specified moisture content level and then introduced into resonator of working chamber of microwave generator, wherein porous organic portion of coal is divided by microwave electromagnetic field-caused "interstitial explosion" into fineness class -d material. Thus prepared coal is then directed into multisection classifier and, after addition of water, classification of class -D particles is performed to form particles of +d o  class, which corresponds to minimum size of particles capable of being further demineralized while separating them into at least two fineness classes. Classification of crushed coal separated into fineness classes is carried out at velocity of restricted precipitation of finest mineral inclusion particles superior to that of coarsest coal organic portion particles. Demineralization in presence of water is carried out by gravity concentration technique for each isolated class to give fineness class -d and -d o  coal and to remove tails of -D and -d o  fineness classes. Demineralized coal is fed into homogenizer. 
     EFFECT: reduced power consumption and coal division and demineralization losses.
