Abstract: A method and device improve efficiency, depth and reliability of diagnosing technical condition of highly complex objects. The technical effect is achieved by signals received from a diagnosed object (DO). These signals are transformed into a technical condition initial estimate vector for the DO elements. Then, technical condition estimates for the DO elements are specified through a cyclical process and by using a reverse logical model and a direct logical model. A technical condition vector estimate is formed after the cyclical process is completed, and its variable components are used for deciding on technical condition of the diagnosed object elements. The device comprises an interface unit which inputs serve for connecting to the DO data outputs, a measuring unit, an initial estimate forming unit, a switching unit, a reverse triplex logical model and a direct triplex logical model, a result interpretation unit and a control unit.

Abstract: The micropump includes continuous cylindrical separating pipes having at least two alternating stages of pipes of small radius and large radius connected in succession. Each pipe of a large radius has one end as a hot zone, and the opposite end as a cold zone. The pipes alternate straight pipes with a large radius and U-shaped curved pipes with a small radius. The relationship of the large radius (R) to the small radius (r) is in a range of R/r=2 to 10000, while the relationship of the temperature (T2) of a hot zone to the temperature (T1) of a cold zone is T2/T1=1.1 to 3.0. The length and radius measurements of a straight pipe and a U-shaped pipe ensure a given change in temperature of the gas from the temperature of the hot zone to the temperature of the cold zone.

Abstract: This invention relates to powder metallurgy, more specifically, to composite material production methods, and can be used for the production of copper base binders for diamond tools used in the construction industry and stone working. The copper binder comprises the following components (wt. %): Copper (30-60), iron (20-35), cobalt (10-15), tin (0-10.5), tungsten carbide (0-20) and an alloying addition. According to the first variant the alloying addition is a nanopowder having a specific surface area 6-25 m2/g, which is present in an amount of 1-15% wt. According to the second variant the alloying addition is a nanopowder having a specific surface area of 75-150 m2/g, which is present in an amount of 0.01-5% wt. The binder possesses a high wear resistance without the essential increase in the required sintering temperature, as well as high hardness, strength and impact toughness.

Abstract: The rotary connector is intended for use in the field of fiber optic communication and information transfer. The rotary optical cable connector includes a housing, in which two units with guide sleeves are arranged opposite one another, each having the ends of optical cables fastened therein. One of the units is able to rotate, and the other is fixed. A prism is situated between the guide sleeves, and retainers in the form of rods with a cruciform cross-section are secured in the sleeves. The optical cables are disposed in the recesses in the aforesaid retainers and the ends of the cables line up with gradient-index lenses. The rotary connector transmits four rotating light beams with minimal loss.

Abstract: Standardized distance minima for longitudinal separation is ensured during flight of a second aircraft behind a first aircraft on take-off or landing of the aircraft on one runway or on two parallel runways located near to each other, or during flight one behind the other at near altitude levels in conditions where there is the risk of turbulence from the vortex wake of the first aircraft possibly being present along the direction of movement of the second aircraft. Continuous monitoring of the level of wake vortex flight safety of the second aircraft is carried out in a buffer zone which surrounds the aircraft and is selected on the basis of the direction of the aircraft outside the standardized distance minimum, taking into account pilot reaction time and the time for the system for controlling the second aircraft to respond to a command to change speed.
