Granted: 2020-05-19
Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to a system of minimal invasive intervention. System comprises a manipulator and a system for assessing the forces acting on the instrument during a surgical operation. Manipulator has a support configured to secure the trocar and to secure the actuator of the surgical instrument. Force evaluation system includes a three-axis lower strain gauge (2), a three-axis top strain gauge (1), a force sensor for capturing tool actuating surfaces and a sensor for rotating the surgical instrument. Three-axis lower strain gauge is located on support of manipulator in point of fixation of trocar and is in direct contact with it. Three-axis top strain gauge is located on the manipulator support under the surgical tool drive. Grip force sensor is made in the form of current sensor for electric motor of tool drive, which provides compression of actuating surfaces of tool. Torque sensor is made in the form of a current sensor for the electric motor of the tool drive, which provides rotation of the surgical tool around its longitudinal axis. Strain gauges are connected to digital data processing modules. Grip force sensor and torque sensor are connected with motor control systems. Digital processing modules and electric motor control systems are connected to a processing module which is programmed to perform the following calculation: forces directed along linear axes; rotary moments of the tool along the x and y axes relative to the trocar insertion point into the patient's body; the tool rotational moment along the z axis relative to the trocar insertion point into the patient's body; forces of compression of tool actuating surfaces. Each digital processing module is programmed to use a digital low-pass filter and a band-guard filter algorithm for said force, measured by a strain gauge. Processing module is programmed to: compensate for gravity acting on support of manipulator and tool; compensation of forces caused by resistance of trocar to movement of tool; compensation for dynamic characteristics of elements arranged on electric motors rotational axis. Processing module is configured to transmit data to the robot-surgical complex control system. 
     EFFECT: invention provides reliable determination of force sources acting on the surgical instrument during operation, as well as accurate measurement of these forces in conditions of high electromagnetic noise.

Granted: 2021-10-07
Abstract: FIELD: gas purification systems.  
     SUBSTANCE: invention relates to the technology of cleaning gases from dust in the heat power industry, ferrous and non-ferrous metallurgy. The method for cleaning gases from dust consists in introducing the gas to be cleaned into a cyclone with an upper axial exhaust pipe. Next, the gas is cleaned from dust in the cylindrical body due to the action of centrifugal forces during the translational movement of the rotating flow from top to bottom in the cylindrical body by turning the purified flow upwards. The collection of the captured dust flow in the dust collector is performed. The supply of auxiliary coagulating liquid to the cyclone is organized, oriented to the flow of captured dust, with the formation of a mixture of captured dust and auxiliary coagulating liquid. The mixture is briquetted on a roller press installed in the lower part of the cyclone body. A flow of briquettes is formed in the above-bunker space, after which the briquettes are loaded into a collecting hopper. The rotating flow of the purified gas is cooled using a heat exchanger that generates water vapor supplied to the above-bunker space. The gas to be cleaned is additionally cooled using a cooler adjacent to the outer surface of the exhaust pipe. Between the cooler and the heat exchanger, the circulation of the coolant is organized by installing circulation pipes. The heat exchanger is equipped with a collecting drum: a water vapor storage tank. The circulation of the coolant is organized forcibly by installing an external pipeline with a circulation pump connecting the storage drum with the lower part of the heat exchanger. A heat-insulated air heater generating heated air is installed on the section of the external pipeline between the storage drum and the circulation pump. The heated air is fed into the above-bunker space through a heat-insulated air pipeline with a flow rate of 0.2-2.5 m 3 /kg of briquettes.  
     EFFECT: invention provides an increase in the efficiency of gas purification from dust by 0.5-2.6% (abs.), the strength of dust-sludge briquettes by 5-14 kPa (abs.) and the drying efficiency of briquettes by 2-7% (abs.).
