Granted: 2002-09-10
Abstract: FIELD: machine engineering, namely casting with use of investment patterns. SUBSTANCE: pattern is made of powder mixture of pattern composition and its mostly easy-to-melt components with fraction size (0.1- 1.6)mm. Relation of mixture components is caused by evaporated quantity of easy-to-melt components during one manufacturing cycle. Method comprises steps of metering pattern material to press-mold in quantity providing manufacture of patterns with porosity degree (3-10)%; without preliminarily heating pressing pattern material due to coinciding parting surfaces of press mold. At pressing powdered pattern material is sintered practically without phase deformation processes at providing open capillary porosity which compensates pattern expansion at heating it during melting-out from ceramic envelope.

Granted: 2003-03-27
Abstract: FIELD: water treatment. SUBSTANCE: invention relates to electrochemical treatment of water to remove organics, preferably injurious nitrogen-containing impurities, and may be applied, for example, to clean industrial waste waters containing hydrazine derivatives and aliphatic amines. Treatment involves (i) chemisorption of impurities on electrodes made from catalytically active materials, in particular from porous carbon materials such as carbon fibers, until stationary filling of electrode surface is attained and (ii) redox destruction of impurities on electrodes. Chemisorption of impurities is conducted at immersion potential characteristic of chosen electrode material in absence of polarization thereof. Oxidation of impurities is conducted by charging electrode to impurities' destruction potential followed by keeping this potential until impurities are completely destroyed. EFFECT: increased cleaning degree and lowered expenses due reduced power consumption and eliminated use of platinized titanium. 6 cl, 5 ex

Abstract: FIELD: mining industry. SUBSTANCE: process of development of gently dipping and inclined coal formations with use of cleaning powered complexes includes excavation of coal in longwall face, keeping of support across junction between development working and breakage face by means of frame support and cross supports with reinforcement of support in zone of bearing pressure and control over formation roof by way of complete collapse of rocks of roof behind powered support. Support of excavation gallery across its matching with breakage face in zone of bearing pressure is reinforced by increase of bearing capability of pliable props of frame support due to installation of brake devices in front of ends of joints in connecting pliable units. Development workings fixed by means of anchors are reinforced by installation of additional stronger and longer anchors between anchors erected before and by their fixing in zone of rocks not subject to intensive displacement. Cross supports of beam structure are attached to formation roof with the aid of anchors of enhanced bearing capability with their fixing in zone of rock mass not subjected to deformation displacement. Monolithic difficult-to-fall roof is loosened by method of hydraulic stratification by injection of fluid or water into wells drilled into formation roof from under powered support. Wells for injection of fluid or water can be drilled along line of matching of breakage face with development working with inclination towards breakage face. Distance between adjacent wells is supposed to be sufficient to secure hydraulic coupling in rock mass after injection of fluid or water into wells. Brake device can come in the form either binding clamps or plates with edges adjustable by depth of cutting.

Abstract: Изобретение относится к химическим средствам, а именно к химическим составам для борьбы с химическими отравляющими веществами. Пенообразующий состав для изоляции поверхностей, зараженных ипритом, содержит пенообразователь, воду, водопоглощающий полимер акриламида. Состав содержит компоненты в следующих соотношениях, мас.%: пенообразователь 3,0; водопоглощающий полимер акриламида 0,05-0,10; вода - остальное. Технический результат достигается за счет образования в водных растворах пенных составов структуры в виде мелкодисперсных частиц полимера акриламида, которые при пенообразовании переходят в пленки пены и препятствуют их обезвоживанию. Также увеличение устойчивости пен объясняется растворением небольшой части полимера акриламида в воде с образованием смешанного адсорбционного слоя на поверхности раздела фаз, с повышенными структурно-механическими свойствами. Изобретение позволяет получать пену с повышенной устойчивостью, способной изолировать поверхности, зараженные ипритом. 1 з.п. ф-лы, 1 табл.
