Title: method and device of extraction by evaporation of solid residues from the fluid
IPC: F26B17/28
Filed: 1993-02-10
Abstract: A method of extraction by evaporation of solid residues from the fluid which is a suspension or solution containing flying substances, in particular, in aqueous medium. The method consists in that the fluid is continuously applied in the form of a thin layer on the first out of two surfaces of the wall of heat exchange, which is heated to the temperature sufficient for rapid evaporation of water and/or other volatile components of medium. Solid and dry residues in proportion to their formation on the first surface are continuously removed by erasure. Heating the wall of heat exchange is achieved with the help of the vapour formed as a result of evaporation, which is subjected to mechanical compression. Then they are introduced into contact with the second surface of the wall of heat exchange, on which the vapour is condensed, and the formed liquid and hot condensate are removed. As the first surface the flat and horizontal surface is used, on which the fluid is applied by pouring with formation of uniform layer maintaining its thickness within the range from 0.2 to 2 mm. The removal of non-condensed substances from the vapour prior to its recompression is performed.

Title: Method for displacement of aircraft that is heavier than environment and aircraft
Inventor: SHULIAK IHOR OLEHOVYCH
Filed: 1998-10-06
Abstract: A method for displacement of an aircraft that is heavier than environment, in which lift is formed by ionization of layer of environment near upper and lateral parts of aircraft, and pressure near these surfaces is reduced. Pressure difference near upper and lateral parts of aircraft and near its lower part forms lift that is tractive force. Ionization is formed by rotation of aircraft propeller. Aircraft that is heavier than environment has casing with rotary propellers – upper, spherical and lateral - box. Box has possibility of rotation in direction opposite to direction of rotation of upper propeller. Part of casing adjacent to upper propeller corresponds by form to lower part of propeller. Aircraft also has additional propellers – channels that connect outer surfaces of upper and lower parts of casing. Invention ensures increase of tractive force per unit of aircraft mass.

Title: Hydro-machine gate
Inventor: Kleschevnikov Valerii Kuzmych
Filed: 2001-06-27
Abstract: This invention relates to hydro-machine-building and can be used in shutoff bodies of hydro-machines. Gate of hydro-machine has housing, rotary bi-plane symmetrical disc, servo-motor, two sets of tightening: the operational tension and the repair pressure ones, this is made as interacting with each other at closed gate of the disc tightening element and movable shell, and power mechanism for the shell displacement; at that the movable shell in working (closed) position goes round the tightening element of the disc and interacts with the last one in cylindrical surface. Possible water leakage through repair tightening falls to the channel between disc belts and is taken out through drainage branch pipe. This invention makes it possible to compensate deformation of the disc of the gate in closed position, thus it makes possible to increase reliability of the repair tightening and, respectively, reliability of the hydro-machine gate in the whole.

Abstract: FIELD: metallurgy, namely rolled stock production, particularly system for cooling rolling rolls of mills for cold and hot rolling of sheets. SUBSTANCE: method comprises steps of setting maximally possible total flowrate of cooling agent supplied onto rolls from all headers; measuring by means of flowmeters individual flowrate V cu.m/h of cooling agent for each header; determining for each header "sprinkling intensity" according to given formula V11= V/F cu.m/h x sq.m, where F sq.m is real surface area of each roll sprikled by cooling agent; comparing sprinkling intensity of each roll with its optimal value corresponding to range 180-220 cu.m/h x sq.m; if V11 is more than 220 cu.m/h x sq.m reducing flowrate of cooling agent until it achieves optimal range; if V11 is less than 180 cu.m/h x sq.m increasing flowrate of cooling agent until it achieves optimal range while using excess cooling agent of previous headers. When quantity of excess cooling agent of previous headers is insufficient for increasing flowrate up to 180 cu.m/h x sq. m at least in one header, - reducing flowrate values of those headers where they are near upper limit of optimal range (reducing only until value no less than lower limit of said range); using additional excess of cooling agent for making up its flowrate in those headers for which flowrate is less than 180 cu. m/h x sq.m until achieving optimal range or its lower limit value; determining flowrate of cooling agent of each jet Vj cu.m/h=V/n, where n is number of jets in header; then according to known characteristics of jet based upon dependance "jet pressure - flowrate" [p=f(Vj)], determining pressure values in jets of each header and setting those values according to optimal range from 5 to 2 due to changing surface area of jet outlet openings that is by increasing surface area at p exceeding 5 excess and reducing it at p being less than 2. EFFECT: possibility for optimizing cooling mode of rolls without increasing total consumption of cooling agent. 2 dwg, 4 tbl
