Damage control cables in electrical phenomenon is quite common. To prevent cable replacement great lengths in serviceable there is a way to repair it, previously requiring a definition of the place of damage. In this case, you must apply a number of methods to determine the place of circuit lived or their place of breakage. In this case, knowing the resistivity lived control cable can be determined by bridges DC. Methodology and methods of measurement of resistance lived control cables are discussed further in the article.

Keywords: Bridge DC, shops resistance, the sensitivity of the bridge

The investigated nanocomposites are characterized by more uniform distribution of amorphous and crystal phases. An optimal number of crystallization centers - nanoparticles leads to improve mechanical properties of polyethylenes. Introduction of nanofillers into a polymer matrix leads to the formation of cryptocrystalline supermolecular structure by reducing of the thermodynamic threshold of crystallization.

The article is devoted steps for the development technical support for crane operator training complex. An important component of technical support is a wireless terminals. Formulated a list of requirements for a wireless terminals: correct operation of the program crane simulator, reliability, compactness, wired and wireless communications to PC, flexible configuration, self-diagnostics, low price. Mobile Remote includes  terminals and host. The host is connected to PC via USB interface, as USB HID device. Terminals transmits the information to a host by Bluetooth. Selected hardware base for the terminals and host (microcontrollers, wireless modules, batteries) and designed printed circuit boards. Investigations of the different batteries and the battery life time of terminals. The description of the design decisions, especially this development.

The concept of creation of energy-efficient areas in cities in the reconstruction and secondary residential blocks and micro-districts consists in the fact that, in practice, to prove the real possibilities to reduce energy consumption per unit area of housing in the housing and communal sphere in two and more times due to the implementation of the already well-known energy-saving technical tools and solutions, rational use of their possible combinations of the specific nature-climatic and city planning conditions. The creation of energy efficient zones requires a comprehensive consideration of issues and the systematic development of power supply at all stages of production, transportation and consumption of energy from the modernization of the objects of the engineering infrastructure

In article results of experiences on studying of aerodynamics of a polydisperse suspension of conversion lime carbonate are resulted. The equations for calculation of speeds and concentration of lime carbonate on length of a tube-dryer are received. The obtained data can be used at designing of industrial dryers.

Keywords: Conversion lime carbonate, drying, tube-dryer, aerodynamics.
