The inventive method for producing nanoparticles for ferrofluids by electron-beam evaporation and condensation in vacuum, consists in evaporating an initial solid material and in fixing nanoparticles to a cooled substrate by means of a solidifiable carrier during vapour condensation, wherein a solid inorganic material, which is selected from a group containing metals, alloys or oxides thereof, is used as an initial material and a solid liquid-soluble material is used as a magnetic carrier material for fixing nanoparticles. The method also consists in simultaneously evaporating the initial material and the carrier composition by electron-beam heating. The vapour is deposited on the substrate, the temperature which is lower than the melting point of the carrier material, and the condensate of the magnetic material nanoparticles, which have a size and are fixed in the carrier, is produced. The particle size is adjusted by setting the specified temperature of the substrate during vapour deposition.

Technique for bonding soft biological tissue having an incision therein with forceps adapted to grip a portion of tissue on both sides of incision. Electrodes are secured to forceps for contracting the tissue portion. An electrical power source provides a high frequency electrical signal to electrodes to be passed through the tissue portion. The electrical power source is controlled to provide electrodes with one voltage signal during a first of two stages, wherein the voltage rises linearly, and another voltage signal during a second of the two stages, wherein the voltage is stabilized and modulated with a low frequency rectangular signal. A clamping means applies force with the forceps to compress the tissue at one or different levels during two time periods while the high frequency voltage is passed through the electrodes. The tissue impedance is measured as a function of time, with its minimal value being determined and stored.

A system and method for welding of biological tissue by applying an RF voltage during a first stage to electrodes of a tissue welding tool; monitoring tissue impedance, and determining a minimum tissue impedance value during the first stage; determining relative tissue impedance; detecting when the relative tissue impedance reaches a predetermined relative tissue impedance value and starting a second stage; calculating the duration of the second stage as a function of the duration of the first stage; and applying the RF voltage during the second stage to the electrodes of the tissue welding tool.

System and method for control of tissue welding

A technique for bonding soft biological tissue having an incision therein with forceps adapted to grip a portion of the tissue on both sides of the incision. Electrodes are secured to the forceps for contacting the tissue portion. An electrical power source provides a high frequency electrical signal to the electrodes to be passed through the tissue portion. The electrical power source is controlled to provide the electrodes with one voltage signal during a first of two stages, and another voltage signal during a second of the two stages. During the first stage the voltage rises linearly. During the second stage, the voltage is stabilized and is modulated with a low frequency rectangular signal. A clamping means applies force with the forceps to compress the tissue at one level or at different levels during two time periods while the high frequency voltage is passed through the electrodes. The tissue impedance is measured as a function of time, with its minimal value being determined and stored. At an instant when the impedance reaches its minimal value, the linear rise of the high frequency voltage is stopped, and the voltage is stabilized at the attained level. After that the ratio of the tissue impedance to its minimal value is determined as a function of time. The passing of the high frequency voltage to the electrodes is stopped as soon as such ratio reaches a preset value, which is specific for each tissue being bonded. The material for making electrodes is selected so that the electrode may serve as an effective heat sink for conducting heat away from the tissue surface. The electrodes are dimensioned relative to the thickness of tissue in a compressed state.

The method consists in that molten metal and slag are obtained in a reservoir and then are poured into a mold and kept there till crystallization of the metal takes place and a shaped casting is produced. Prior to the process of pouring, the mold is moved towards the reservoir so that their upper end faces adjoin each other to form a closed integrated unit, which is turned in a vertical plane to transfer the metal and slag into the mold. The joint of the mold with the reservoir in the process of pouring is tightened by providing a time delay for this process from the moment of covering the joint with a slag layer till the moment of solidification of this layer. In the device for producing the castings, the mold and reservoir are provided with individual drives rotating them in a vertical plane, the drives moving the mold to form a closed integrated unit with the reservoir and rotating this unit in the process of pouring the molten metal and slag into the mold.

The method consists in that a flat work in an initial position is oriented horizontally between cooled mold beams. Plasma torches are arranged in line across the parallel side edges so that the anode spots of the extreme torches are confined by said edges of the work. By supplying a plasma forming gas and electric current to the plasma torches the work is heated with the formation of a metal pool which extends across the work from edge to edge. By relatively moving the work and the plasma torches in a horizontal plane and along the edges of the work movement of the metal pool over the surface thereof is effected and thereby a remelted layer as thick as the pool is deep, is obtained. The apparatus for carrying out the method comprises a sealed chamber containing a mold having two beams arranged in a horizontal plane and being parallel to one another. Installed in the chamber are plasma torches mounted on shafts and connected through supply lines with the sources of plasma forming gas, electric current and cooling water. Each of the shafts is journalled in a sealing bush installed in the wall of the sealed chamber so that the axis of the shaft is parallel to the beams. Each shaft is rotatively driven by a drive. The apparatus further comprises a drive for relatively moving the work and the shafts in the plane parallel to the beams, connected with at least one of the elements taking part in such movement. The practice of the method with the help of the apparatus of the invention permits a high-quality work of a predetermined macrostructure of a surface layer, to be produced at a higher rate of treatment.
