Abstract: FIELD: converter engineering; power supplies for induction heaters. 
     
     
       SUBSTANCE: proposed current inverter built in the form of single-phase bridge around transistors with series-connected diodes and transistor shunting diodes is provided with newly introduced series circuits of which one incorporates voltage limiter and two resistors, other circuit has voltage limiter, and third one, two resistors, two diodes, and two capacitors. Each series circuit shorts out single-phase bridge built around transistors and connected to input leads through filter chokes. Third series circuit is connected to collector and emitter groups of single-phase bridge transistor through fourth and fifth series circuits, each incorporating diode, resistor, and choke. In case of open circuit in induction heater thyristor is turned on to short out single-phase bridge through capacitor that limits input voltage of inverter in response to thyristor failure. Input voltage of inverter is limited by limiting voltage across first series circuit. 
     
     
       EFFECT: enhanced operating reliability and noise immunity of current inverter; reduced switching loss and voltage surges.

Abstract: FIELD: chemical industry; designs of the bubble-type reactors for production of 1.2-dichloroethane. 
     SUBSTANCE: the invention is pertaining to the design of the bubble-type reactors for production of 1.2-dichloroethane by the method of the liquid-phase chlorination of ethylene with the reaction heat removal at boiling of the working medium. As the contact device the reactor uses two layers of the metallic nozzle. The liquid 1.2-dichloroethane is fed from above to the nozzle, into the space between the layers of the nozzle feed the gaseous chlorine with nitrogen, and under the lower layer of the nozzle feed the gaseous ethylene with nitrogen, that allows to reduce the diameter of the reactor in 1.5-2 times due to the increased effectiveness of stirring and formation of the developed contact surface of the phases. At that the heat of the reaction is removed by evaporation of 1.2-dichloroethane in nitrogen. At that the temperature of the liquid is maintained below the boiling temperature. The technical result of the invention is the increased selectivity of the process, reduction of the outlet of the by-products (the highest ethane chlorides) and the decreased overall dimensions of the reactor.
