This paper presents multimode waveguide Van-Atta array based on a pair of waveguide radiators. For dispersionless transmission lines we selected 3 coaxial lines, located inside a metal box, which frames the waveguides. Experimental data of monostatic radar cross-section diagram of antenna array in 6-12 GHz in frequency domain are obtained. Experimental study was performed in anechoic chamber of Share Scientific Center “Applied electrodynamics and antenna measurements”, Southern federal university. The subject of research was a model of multimode waveguide Van-Atta array based on a pair of waveguide radiators with aperture size 50*10 mm. An array placed in shield in the form of an elliptical cylinder. This configuration provides an opportunity to decrease ghost reflection from connectors and interconnection cable. A method for compensation background reflections, which experimentally performed on a model of multimode waveguide Van-Atta array, located inside an elliptical cylinder is proposed in this paper. This condition is completely accurate to the real usage conditions. This method is necessary for the research of objects with RCS commensurable with RCS of anechoic chamber. Backscattering diagrams, produced by aperture of Van-Atta array without background reradiation from constructional elements is obtained.

Carry to the main advantages of galvanic ways of restoration: possibility of formation of a layer from several micrometers thick to 1-2 mm. metal or a combination of metals with the set properties, restoration "in the size", that is without the subsequent machining, simultaneous restoration of several surfaces and use of a small amount of electrolyte. A number of the devices allowing to provide the demanded conditions is developed for implementation of galvanomekhanichesky sedimentation of coverings. As the activating elements in these devices generally apply abrasive materials which working surface, in the course of work, "is salted", that is it is hammered with cutting products. It considerably reduces efficiency of activation of the cathode and uniformity of the received deposit in view of introduction in the formed layer the activating elements of products of activation. The offered device developed by Zakharov Yu.A. and Spitsyn I.A. it is deprived of such shortcoming in view of application of the activating elements in the form of leaders and the conducted abrasive rollers connected by a belt drive. For elimination of this lack of the existing devices by Zakharov Yu.A. and Spitsyn I.A. (patent No. 2503753) the device was developed for galvanomekhanichesky sedimentation of coverings on internal cylindrical surfaces of details. Difference of the offered device is that at sedimentation of an electrodeposit, the conducting and conducted rollers, being rolled on the activated cathode surface, rotate with various district speed because of their various diameter. As pulleys of leaders and the conducted rollers are connected by a belt drive, to the transfer relation no more than 0,8-0,9, on shaft of rollers there is various district force forcing the conducted rollers to slip rather cathodic surface. It provides better removal of the passivating film and continuous change of the surface of the activating roller contacting to the activated cathodic surface. Thus, the free surface of the activating roller is washed by a channel of electrolyte, being cleared of activation products that interferes with formation of so-called "zasalivaniye" of a wor1king surface of the activating elements (rollers).

Abstract: Operation of motor transport and special equipment is carried out in difficult conditions, the impact of environmental conditions (temperature, humidity, dust, wind, solar radiation) and changes in modes of operation of the machine. This affects the performance of equipment, the number and complexity of repairs. Away from fixed bases (in the field), the problem is particularly acute repairs. One of the most energy-intensive and expensive works are welding (welding parts with a break, welding cracks, fusing metal layer on the worn surface, metal cutting). In this work the welding equipment affect the voltage drops in the supply mains, therefore, produces a large number of failures such equipment. After the equipment is accompanied by an increased amount of electric power consumption, this results in material costs. Previously proposed equipment has improved mass, which reduces the efficiency of the welding. Based on this study was proposed innovative design welding inverter using the resonance effect, with enhanced reliability, low-cost design version (in terms of mass production). In order to improve the reliability and reduce the cost of the proposed design of inverter proposed a number of new approaches. Full-bridge inverter is studied welding power source with the implementation of the resonance effect with a stable and smooth operation, high reliability, because the circuit of the inverter is not sensitive to changes in the supply voltage.
