Abstract: FIELD: railway industry.  
     SUBSTANCE: invention relates to devices for controlling the status of running rail tracks. Monitoring is carried out by devices that are located at the electric interlocking post (EI) and linear installations (LI), the devices of which are placed in transformer boxes. The rail circuits are mounted with power supply from the middle, 800-1200 m long. Each rail circuit contains two rail tracks 400-600 m long. The station is provided with devices that control the track section from the station to the middle of the running line, the remaining part of the track is controlled by the adjacent station devices. The station is equipped with as many sets of control devices as there are tracks to this station; each station complete unit contains a track generator, track receiver and calculating machine. The counting unit consists of several chain-connected counters. Linear installations are equipped with similar calculating units that work synchronously with the station ones. The synchronous operation of the counter circuits is achieved by the fact that they operate from a single TG generator. The same TG generator also supplies power to track circuits and microelectronic devices of linear installations. The calculating machines control the electronic keys, which are alternately connected to the track generator TG and track receiver TR, the rail lines RL of the halves of the running line. The connection of station devices to the rail lines RL is performed using wires TG1, TG2, TR1 and TR2 for the time T c  = tn, where T c  is the time of one rail line control, t is the duration of the sinusoidal pulse from the track generator TG, n is the number of pulses for monitoring the rail line (8-16). The frequency of the track generator TG can be selected in the range from 400 to 800 Hz, depending on the distance between stops and insulation resistance.

Granted: 2021-05-19
Abstract: FIELD: space technology.  
     SUBSTANCE: invention relates to space technology. The method for separating payloads (PL) from the orbital stage (OS) of the launch vehicle is based on the use of unused remnants of liquid propellant components based on their gasification, ensuring the angular position in space and stabilization. The motion of the center of mass and around the center of mass of the OS is controlled by separate discharge of gasification products from the fuel and oxidizer tanks through adjustable nozzles (holes) of the gas-reactive system. The formation of the control and stabilizing actions is carried out by changing the critical section of the nozzle (hole) for the discharge of the steam-gas mixture from the tanks to the gas distribution station in each stabilization channel.

Abstract: FIELD: medicine; traumatology; orthopedics.SUBSTANCE: invention relates to medicine, namely to traumatology and orthopedics, and can be used for postoperative treatment of hip fractures. Before the beginning of the fracture consolidation, a computer simulation of osteosynthesis is performed with the determination of the initial maximum permissible load (IML) on the limb in terms of osteosynthesis in kilograms. Then the load difference (LD) between the initial maximum permissible load and the full load on the femur is calculated, equal to the patient's body weight. Next, the coefficient of the consolidation period is calculated. Based on the data obtained, the permissible load on the limb (PL) is calculated in kilograms.EFFECT: method reduces the risk of complications associated with improper dosing of loads, such as secondary displacement of fragments, fracture or migration of metal structures, violation of the consolidation of the fracture and the formation of a false joint, the formation of joint contractures, and accelerates the consolidation of the fracture by eliminating early and disproportionate load on the limb.1 cl
