Abstract: FIELD: process engineering. 
     SUBSTANCE: invention relates to ore dressing, particularly to extraction of noble metals. Washing device comprises sand preparation and transfer unit consisting of loading bin, hydraulic washing unit, hydraulic elevator with sluice pipe, coarse gold trap representing a deep filling lock, fine gold trap representing at least two stationary lock-screens with smooth locks with V-shaped bottoms arranged there below, and dressing unit. Additionally, the proposed device comprises suspension-carrying flow solid phase grading and screening and valuable component after-entrapping unit to extract said component from mesh plus of lock-screen representing smooth trough with W-shape bottom. The end of each recess of said bottom has widening slots to withdraw sand heavy fractions to be directed into mesh plus dressing units. Smooth V-shape and W-shape locks are furnished with vertical stilling plates arranged over their entire length, symmetrically on both sides and with clearance with respect to bottom. Stationary lock-screen perforation represents elongated and staggered slots directed along normal relative to lock-screen lengthwise axis. To increase the yield of minor, fine and dust-like particles of heavy noble components, smooth locks with V-shape bottoms feature smooth narrowing of sides. Note here that semi-bottoms of said smooth locks are arranged at an angle each other with smooth decrease in said angle from lock loading to unloading sides from 140° to 100°, while sides of each smooth lock are arranged in plan at the angle to central geometrical axis equal to 6°.

Abstract: Изобретение относится к горной промышленности и строительству, а именно к способам взрывания горных пород с твердыми включениями на открытых горных работах. Такие включения могут быть представлены прослойками крепких пород, различными линзами и другими образованиями, в том числе многолетней (вечной) мерзлоты во вмещающих менее крепких породах. Достигаемый технический результат заключается в повышении эффективности дробления различных твердых включений, находящихся в верхней и средней части уступа и расположенными во вмещающих менее крепких породах. Указанный технический результат достигается за счет того, что заряды ВВ в дополнительных укороченных скважинах располагают на уровне или ниже почвы твердых включений и взрывают с замедлением относительно зарядов в основных скважинах. Предлагаемое изобретение позволяет осуществить эффективное дробление твердых включений, предварительно разупрочненных взрывом зарядов в основных скважинах, за счет динамического воздействия взрывных газов от взрыва зарядов в дополнительных скважинах на нижнюю часть включений. 1 з.п. ф-лы, 2 ил.

Abstract: FIELD: printing industry. 
     SUBSTANCE: invention relates to counterfeit-proof documents and to a multilayer protective element with an alternate optical effect and a counterfeit-proof document. The multilayer protective element comprises a flexible bearing layer with optically alternating structures, contains two or more groups of repeating images, which move and/or change as the angle of observation varies. Optically alternating structures are formed so that whenever the angle of observation changes, various groups of images move relative to each other. Movement of images referred to various groups takes place in parallel to the plane of the observation angle variation so that images approach or move away in respect of an observer, or movement of images related to various groups takes place perpendicularly to the plane of the observation angle variation so that images move to the right or to the left from the observer. The counterfeit-proof document includes at least one protective element. 
     EFFECT: invention makes it possible to increase items security by development of a new optical effect that increases recognition of a secured object based on observation of mutual movements of images as the angle of observation changes.
