  THE PRINCIPLES OF PROGRAMMED CONTROL OF THE ELECTRIC DRIVE BILLET SHEARS
Principles of creation of microprocessor system of program management by the electric drive of billet shears of billet rolling mills, providing significant reduction of the charge of the electric power and decrease of load capacity of the equipment are offered, mathematical modeling proves informatively-manager parameters of system and its efficiency is proved; the variant of realization of principles is resulted.

  STRESS - STRAIN STATE OF HEAVILY LOADED CONNECTING RODS (PULL RODS) OF THE MECHANISM OF CUTTING OF BILLET SHEARS
The some results of computer investigations by a method of finite elements of the flat stress -strain states in consideration of concentration of stresses of real designs of connecting rods of the mechanism of cutting of shears billets rolling mills are shown. They quote the relationships which link the levels of the maximum stresses in the pull rods with their design parameters, which determine their design version and the new design of the increased carrying capacity and smaller metal consumption is submitted.

  THE METHOLOGY OF PARAMETRIC OPTIMIZASHION OF DETAILS AND DESIGNS OF COMPLEX CONFIGURATIONS
The opportunity is substantiated and the algorithm of stage-by-stage consecutive parametric optimization of carrier details and designs of the complex configurations, based on correct application of strict mathematical methods is offered, serviceability and efficiency which is proved of many years practice of designing of the equipment of heavy mechanical engineering

  FATIGUE PROPERTIES OF THE MATERIAL OF LARGE-SIZED DETAILS
Unique statistically exact and reliable estimations of parameters of curves of fatigue of materials of the samples, which have been cut out from large-sized forgings in external diameter of 1300 mm from four marks steels, from which produce bearing details of the metallurgical equipment were presented, at fatigue tests for a bend with rotation and a symmetric cycle loading, and also the full probabilistic diagrams of fatigue, displayed by the equations of regress, containing new parameter - probability of destruction, and possessing high accuracy and reliability.

  OPTIMIZATION OF TECHNOLOGICAL REGIMENS, PARAMETERS OF PROCESSES ROLLING AND THE EQUIPMENT OF REVERSIBLE AND CONTINUOUS ROLLING MILLS
The methodology and mathematical statements with various criterion functions of problems of optimization of technological regimens and parameters rolling on the reversible and continuous rolling mills, based on correct application of principles of the system analysis and strict mathematical methods of the theory of optimum control are presented.

  NEW TECHNOLOGIES AND THE EQUIPMENT FOR PRODUCTION OF HIGH-QUALITY BILLETS AND HEVY I-BEAMS
On the basis of the results of experimental researches in production conditions of process rolling of the large billets in four-high calibre by the scheme of all-round compression, the high intensity of three- dimensional deformation, peculiar to this technology, as well as the high quality of metal ( the equiaxial grain) and the high mechanical properties of received rolling productions are shown. The design of the four-high stand collet of the type, realizing this technology, and promising the versions its of applications, at reconstruction of the continuous billet, medium- and small section mills, as well as in rolling conversion of continuously cast billets are offered.

  

  DRIVE SYSTEM FOR ELECTRICAL VEHICLE
A lot of allowed operating points for this mode must be turned up inside green area of the shown mechanical curve. A lot of allowed operating points for this mode must be turned up inside red area of the shown mechanical curve and must has limited duration. Duty cycle of the each overload mode must be chosen to prevent overheating of the motor (or will be limited by temperature feedback inside power controller).

  MAGNETIC COLLECTOR ADSORBENT FOR REMOVAL OF OIL SPILLS FROM WATER SURFACE AND SOLID SURFACES
Neftakleen is the material converting oil products into magnetic susceptible materials thus providing collection of oil spills from water surface as well as from solid surfaces, by magnetic field.

  DIAGNOSTIC ABILITIES OF MULTIFUNCTIONAL COMPLEX AMP (AUTOMATIC NONINVASIVE METHOD OF DETERMINATION OF BLOOD TEST) AND PROGRAM ‘USPIH’...
AMP allows to get a clinical blood test of any patient without input during 1 minute. Then these data processed by program "USPIH". Program "USPIH" allows: to estimate the state of organism from the position of its functional, hemodynamic equilibration, water metabolism and gas homeostasis, that are connect with fermentative and immunological correction; to define a predisposition to diseases of central nervous system, cardiovascular system, internal, locomotor apparatus, circulation of the blood, metabolism and other pathology.

  CONSTANTLY INCREASING POSSIBILITIES OF P/M TECHNOLOGY
The capsule is a disposal technological fixture. Its internal cavity reproduces the part shape taking into account shrinkage and allowance for subsequent machining. Manufacturing technology of the part from 3-D model to the finished part significantly cuts down the part’s manufacturing hours. The produced part ensures high technical characteristics being not inferior to forging parts.


Here, the recent advanced technologies are stored.

We render our services to individuals and legal entities, which are interested in getting additional information on each technology, free of charge. To receive this information, you just have to send us an inquiry on the technology you are interested in. Sending an inquiry, you have to clearly substantiate your business interests (ref. to the application form). We do not reply to the inquiries, which were sent with a private (on the contrary to business) interest.

These inquiries enable those, who are originally interested in one or another development, to obtain additional information to make a final decision on the purposefulness of negotiating with a developer. Therefore, the inquiries will save both your valuable time and transport expenses, which you are generally losing during direct but unsuccessful negotiations.

If you are an author or an owner of technology and badly need funding, your chances of finding a reliable partner or an investor will rise if you place your information on our website and establish, with our assistance, direct links with banks, legal entities or individuals seeking an opportunity to invest their unbound money in a profitable deal, or with those who want to implement your development. To know terms and conditions of placing your technology description on our website, read here, please. The related services are free of charge.

Our operation sequence is as follows: we place and popularize a matter you have sent us pertaining to the technology, and obtain inquiries from would-be customers (or investors); we communicate with the said would-be customers and address you additional questions they raised over your technology, and you, in your turn, answer these questions, sending us your replies; in this process, we filtrate customers and deselect those who are not interested in doing business but perusing their own interests; if we managed to find an actual investor or a buyer and if we have all reasons to expect the income of investments or the acquisition of your development in the nearest future, then we offer you to sign an actual contract with us; after striking the deal, we establish a direct contact between you and your customer; thereafter, you deal with the customer directly.
