Abstract: FIELD: medicine. SUBSTANCE: method involves determining capillary blood erythrocyte sedimentation rate under the influence of β-adrenoblocking properties of obsidane (propanolol) taken in 1×10 -9  g/ml concentration when added to 5% sodium citrate solution applied for determining blood erythrocyte sedimentation rate under condition the initial blood erythrocyte sedimentation rate being greater than 10 mm/h. When added, obsidane causes blood erythrocyte sedimentation rate drop in cases of normal β-adrenoreactitvity. Beta-adreno-dependant blood erythrocyte sedimentation rate being 85-95% of control blood erythrocyte sedimentation rate, erythrocyte adrenoreactitvity is to be assessed as moderate(normal) one. Beta-adreno-dependant blood erythrocyte sedimentation rate being greater than 95%, erythrocyte adrenoreactitvity is to be assessed as reduced one. The case of less than 85% is to be assessed as raised one. EFFECT: enhanced effectiveness in setting early stage diagnosis, prevented premature birth; enhanced accuracy in determining degree of readiness to birth. 1 dwg

Title: Loose material drier
Inventor: MOROZOV G A
IPC: F26B3/347
Filed: 1998-03-05
Granted: 2000-07-10
Abstract: FIELD: mechanical engineering; drying facilities. SUBSTANCE: invention relates to equipment designed for drying loose materials such as granulated plastic, grain, ore samples. After loading of loose material into drier, rotation drive 14 (speed from 3 to 10 rpm), microwave oscillator 5, air heater 9 and fan 11 are switched on. As drum 1 rotates slowly, and loose material (granules or grain) is relatively heavy, material does not spread over entire volume of drum 1 but is turned only through angle of 45 o  so that wave-slot resonance radiator system 6, turned through the same angle, radiates microwave power directed square to loose material layer. Ribs 4 provide stirring of loose material for uniform heating. Moisture evaporated from loose material is heated by hot air and is let out through channel 10 by means of fan 11. Use of decimetric wave band magnetron of I-kW power rating and air heated to 60 C provide drying of up to 50 kg of granulated plastic in 40 minutes. Drier provides drying of loose materials to moisture content not exceeding 3% at external temperature acting onto material not exceeding 60 C (for instance, maximum tolerable temperature of drying for polystyrene-based composite materials should not exceed 80 C). EFFECT: accelerated drying of materials. 3 cl, 2 dwg

Title: Tunnel lining
IPC: E21D11/08
Filed: 1998-06-04
Granted: 1999-07-10
Abstract: FIELD: tunnel building technology. SUBSTANCE: procedure can be used in building of subways, vehicular traffic tunnels and reinforced concrete tunnels in watered medium at hydrostatic pressure above 0.15 MPa and at inflow of water to work face above 20 cu.m/h. Tunnel lining is made up of reinforced concrete blocks having curved metal sheet at their internal side creating reinforcement and hydraulic insulation. Welded to metal sheet are metal strips along edges at side facing inside concrete block which create ribs. Rigidly fastened to ribs are anchors so as to create grooves between adjacent lining blocks. Each lining block is provided with additional metal strips which are located discretely at calculated pitch. These metal strips also create ribs. Additional metal strips are rigidly fastened to sheet at side facing inside lining block and oriented across longitudinal axis of tunnel. Also provided are additional anchors which are rigidly secured to additional strips. Extreme metal strips are fastened to sheet so as to create overhangs. Length of overhangs is not over half of sheet thickness. Distance between end-faces of sheet overhangs of adjacent lining units is equal to not less than two values of sheet thickness. Walls of grooves between adjacent lining blocks are created by extreme metal strips of these block. Grooves are filled with caulking material. Aforesaid technology of tunnel lining allows for reducing amount of metal needed for construction and cutting labour cost. This is achieved due to optimal selection of rigidity of metal sheet by providing it with wisely arranged ribs together with provision of caulking grooves which prevents necessity of using additional metal sheets which overlap joints and their welding. This ensured utilization of such improved metal sheet which simultaneously functions as reinforcement and hydraulic insulation and made possible to give away from utilization of traditional reinforcing framework by development of structure which is simple and inexpensive in manufacture which can replace expensive cast iron tubings which are hard to produce and erect. EFFECT: higher efficiency. 5 dwg
