Granted: 2001-08-20
Abstract: FIELD: electrical engineering, electric steel making and welding equipment. SUBSTANCE: secondary winding of each phase is made of two parts connected to one electrode through rectifiers. In this case one part of secondary winding is designed for total electric power and maintenance of low-voltage arcing and its other part is continuation of first part jointly generating voltage of initiation of arc under all real operational conditions of furnace and has minimal power. It is connected in series with choke or adjusting resistor. Electric arc is initiated thanks to uninterrupted or intermittent transition from stable low-power discharge under action of voltage in entire secondary winding. As arcing develops high-temperature plasma is formed. Due to drop of voltage across choke potentials of both parts of secondary winding are leveled and load on them is distributed in inverse proportion to their resistance. EFFECT: decreased cost, increased operational efficiency and other operational indices of arc furnaces. 2 dwg

Abstract: FIELD: methods of clearing of hydrophobic pollution from water or solid surfaces. SUBSTANCE: the invention presents a method to clear a water or solid surface from a hydrophobic pollution with the help of a magnetic foam, the walls of which contain magnetic particles of nanometer sizes. The foam is produced on the site of its applications in necessary amounts from compact source materials with the help of the stationary or portable installations. The foam, that has absorbed the pollution, is gathered by the magnetic collectors. The gathered foam is then destructed, and a separated magnetic component may be reused. The fast absorption of a hydrophobic pollution, for example petroleum, by the foam ensures an opportunity practically at once to gather and remove the foam from a cleared surface with the help of the magnetic collectors, and the high speed of generation of the foam - to apply the foam repeatedly, that allows to increase efficiency of gathering of a hydrophobic pollution from a water or a solid surface. EFFECT: the invention allows to increase efficiency of gathering of any hydrophobic pollution from a water or a solid surface. 1 ex
