Abstract: FIELD: sportive equipment. SUBSTANCE: method involves moving sportive equipment or model thereof along predetermined track portion; providing multiple measurement of movement parameters; selecting optimum version; providing movement measurements at equipment or model thereof at speeds exceeding at initial and final measurement periods rest state. Speeds at initial and final measurement periods are determined between two points for each period, with distance between two points for each period being equal. Acceleration is determined at the portion having distance 2-4 times exceeding distance between first and terminating points of both periods. Sliding coefficient is calculated from formula   where g is gravity force acceleration; a is acceleration of sportive equipment or model thereof at predetermined track portion equal to  , where b is distance between first and terminating points of any period of speed measurement of sportive equipment or model thereof; S is distance between middle parts of periods; t 1  is first period of time; t 2  is final period of time. Method allows optimum sliding surface and lubricant for it to be effectively determined and may be applied for sportive events and equipment, such as skiing, snowboarding, sledge event, skating, all kinds of rowing. Method also allows operational factors such as friction of ski sliding surface lubricated with different lubricants under real ski conditions to be completely taken into account.

Abstract: FIELD: polymer production. SUBSTANCE: invention relates to large-scale production of urea-formaldehyde resins, including modified ones, and can be used at potassium industry enterprises, for example at flotation plants where resins are used as depressants. Urea-formaldehyde resins are prepared by stepped ureaformaldehyde condensation in variable- acidity media (first in alkaline medium and then in acidic medium) at heating in presence of modifying agent containing polyethylenepolyamine in acidic condensation step and with extra urea added in alkaline condensation step. According to invention, 40-45% polyethylenepolyamine solution in 20% sulfuric acid is used as modifying agent in amounts 25% of the weight of carbamide involved in condensation process. Initial and final urea-to- formaldehyde molar ratios are 1: (2.2- 2.35) and 1:(2.0-2.2), respectively. Alkaline condensation is carried out at pH 8.5-9.1 and 74-78 C for 30 min, and acidic condensation at pH 4.2-6.1 and 70-80 C. EFFECT: reduced toxicity of resins at lower cost. 1 tbl, 5 ex

Abstract: FIELD: petrochemical processes. SUBSTANCE: olefin hydrocarbons are produced by dehydrogenation of paraffin hydrocarbons in fluidized bed of dust catalyst circulating within reactor-regenerator system. Process comprises preparing hydrocarbon mixture form direct and recycle streams of paraffin hydrocarbons, vaporization thereof, heating hydrocarbon vapors by heat of contact gas and overheating them in furnace and passing them to fluidized-bed catalyst dehydrogenation. After that, contact gas is cooled in heat-recovery boiler. Coke formed in the process is burned out when catalyst is subjected to air oxygen oxidation in regenerator followed by reducing catalyst with natural gas, conveying catalyst form reactor into regenerator and vice versa, compressing contact gas, condensation and recification-mediated isolation of paraffin and olefin hydrocarbon fraction from condensate. Content of oxygen in reduced catalyst entering reactor, according to invention, is maintained between 0.025 and 0.075 wt % using for that aim stripping catalyst with inert gas passed at flow rate 0.25 to 1.25 cu.m per 1 cu. m circulating catalyst. When content of oxygen in reduced catalyst rises, inert gas intake is decreased. EFFECT: enhanced process efficiency and reduced raw material and catalyst losses. 3 cl, 1 dwg, 12 ex
