Abstract: Изобретение относится к области медицины, а именно стоматологии, и может использоваться для определения степени пародонтита у пациентов всех возрастных групп. Осуществляют определение глубины патологических пародонтальных карманов обследуемых зубов с медиальной, дистальной, наружной и внутренней поверхностей зуба при помощи стоматологического пародонтометра с последующим определением максимального значения их глубины, и при наличии полученного максимального значения менее 4 мм определяют I, то есть легкую степень пародонтита, при значении 4-5,9 мм - II, то есть среднюю степень пародонтита, при значениях 6 и более мм определяют III, то есть тяжелую степень пародонтита. При этом глубину патологических пародонтальных карманов обследуемых зубов дополнительно определяют по всей ширине вышеуказанных 4-х сторон каждого обследуемого зуба с помощью стоматологического пародонтометра с делениями на рабочей части от 1 до 10 мм с шагом в 1 мм, и после его введения в патологический пародонтальный карман пародонтометр отклоняют на острый угол от оси зуба. Причем после определения глубины каждого патологического пародонтального кармана каждой поверхности каждого зуба стоматологический пародонтометр выводят из вышеуказанного кармана с последующим его очередным введением в этот же карман, при этом отступают от предыдущего места его введения на ширину рабочей части пародонтометра, причем выведение стоматологического пародонтометра из вышеуказанного кармана с последующим его очередным введением в этот же карман осуществляют до полного обследования каждой поверхности каждого зуба; максимальное значение глубины патологических пародонтальных карманов обследуемых зубов определяют путем выбора максимального значения глубины в области каждой поверхности каждого обследуемого зуба. Способ позволяет повысить объективность определения степени пародонтита и обеспечивает возможность определения глубины патологических пародонтальных карманов независимо от топографо-анатомических особенностей обследуемого пародонта, при наличии несъемных стоматологических ортопедических конструкций, а также в случае скученности зубов, наклоне зубов по оси в разных направлениях и нависании несъемных стоматологических ортопедических конструкций. 1 з.п. ф-лы, 28 табл., 6 пр.

Abstract: FIELD: poultry farming.SUBSTANCE: invention relates to a method for sorting eggs; it can be used in poultry farming and in the poultry processing industry in the mechanization and automatization of the sorting process of substandard products. A method for detecting substandard products in an egg tray consists in that filled egg trays are moved on a conveyor through a detection system containing a video camera connected to a technical vision controller that processes an image obtained from the video camera. The detection system also contains a sensor for the presence of products on the conveyor and a conveyor for the removal of substandard products. At the same time, the image of the tray is recorded using the video camera and/or the sensor for the presence of products and transmitted to the machine technical vision controller that processes the image. Depending on the type of a detected object - tray, an algorithm for counting the number of eggs for trays with a capacity of 20 and 30 eggs and an algorithm for matching the packaging geometry for closed trays with a capacity of 10 and 15 eggs is launched. At the same time, an algorithm for detecting marking on found eggs is launched by searching for the image of marking on the top of the egg and detecting it as an object of a different color from the color of the egg, and a geometric shape. At the same time, pieces of dirt and crashed products are detected as follows: the egg search is trained to search for an oval shape with filling of a uniform color within the specified limits. The insufficiency of filling with one color gives a signal about an undetected egg, which in turn forms a signal about insufficient laying. Based on image processing, a video camera controller generates several signals: the presence of an object in the camera, or a signal about insufficient laying, or a signal about the absence of marking, or a signal about the presence of dirt. The controller of the conveyor system receives the specified signals and, based on them, controls a pneumatic cylinder, using which substandard products enter the removal conveyor, and standard products are delivered further along the conveyor to the packaging.EFFECT: invention provides for the search and sorting of substandard products in group egg packaging.1 cl, 2 dwg

Abstract: FIELD: gas industry.  
     SUBSTANCE: invention relates to the field of extraction and preparation of gas and gas condensate for long-distance transport. A method for automatic control of heat losses of recuperative heat exchangers (HE) at low-temperature gas separation plants is proposed. The automated process control system (APCS) measures the temperature of the heating thermal liquid with a given time discreteness, as well as the mass flow rate of the heating and heated thermal liquid at the inlet and outlet of the first and second sections of the “gas-gas” HE and “gas-condensate” HE. For each measurement moment, the APCS calculates the actual thermal efficiency for the HE. The results of calculating the thermal efficiency when starting the installation for the first measurement are stored by the APCS as a reference value, and the APCS uses the obtained values to plot the continuous time function graph ƒ(t). If the ƒ(t) graph changes within the permissible variations, then the operation of HE thermal insulation is carried out without any restrictions. As soon as the deviation of the graph from the reference values reaches a critical value or exceeds it and continues to grow, the APCS generates a message to the installation operator.  
     EFFECT: reduction in the cost of repair work.
