Abstract: Изобретение относится к сельскому хозяйству, в частности к пчеловодству. Способ прогнозирования сохранности пчелиных семей включает использование для анализа извлеченных ректумов пчел. При этом из пчелиной семьи отбирают до 30 ректумов, измеряют у каждого из них их ширину и определяют количество переполненных зон экскрементами. Для этого используют бинокулярный микроскоп с калиброванной линейкой, с помощью которой проводят горизонтальную линию от начала и до конца ректума, затем к этой горизонтальной линии проводят перпендикулярные линии от высших точек до нижних, по которым измеряют ширину ректума, и по количеству промежутков между перпендикулярными линиями определяют количество переполненных зон его экскрементами. Затем ранжируют ректумы по степеням переполненности в зависимости от их ширины и количества переполненных зон. К 1-й степени переполненности относят ректумы, ширина которых более 3 мм, а количество переполненных зон - 4 и более. Ко 2-й степени переполненности относят ректумы с шириной 1,5-2,0 мм и с количеством переполненных зон не более 3. К 3-й степени переполненности относят ректумы с шириной 1,5-1,8 и с количеством зон не более 2. Если количество ректумов 1-й степени переполненности преобладает над количеством ректумов 2-й и 3-й степеней, то семью пчел относят к категории низкой сохранности, а если количество ректумов 2-й и 3-й степеней переполненности преобладает над 1-й степенью переполненности, то семью пчел относят к категории высокой сохранности. Изобретение обеспечивает возможность прогнозирования сохранности пчелиных семей. 2 ил., 1 табл.

Title: Method for measuring parameters of hinged fork groove
Inventor: Arkhanov Anatolij Pavlovich
IPC: G01B5/02

Granted: 2021-06-01
Abstract: FIELD: measurement techniques. 
     SUBSTANCE: invention relates to methods for measuring the width and symmetry of a groove in parts in the form of a hinged fork. The hinged fork is positioned in the inclined body by mounting it on the reference and positioning prisms. The mutual angular position of the hinged fork and the inclined body is verified by means of reciprocating movements of the hinged fork around the longitudinal axis of the tail part on the base prism and a probe with a rod around the longitudinal axis of the rod. The reciprocating movements of the measuring probe with the rod are carried out in a plane parallel to the common bisector plane of the basing and mounting prisms, thus achieving invariability of the readings of the reference head when the measuring probe touches the lateral surface at two extreme points in the direction of the groove length. The first reading is taken. The measuring probe is brought into contact with the other side surface, the second reading is taken. The measuring probe is rotated around the longitudinal axis of the rod and moved along this axis, achieving the centering of the measuring probe along the mounting prism by simultaneously touching the lateral working surface of the probe with the working surfaces of the mounting prism. The third sample is taken. Based on the data obtained, the width of the groove and the deviation from symmetry are determined.  
     EFFECT: increased accuracy of measurement.

Title: Method for intensifying the main combustion period in a diesel engine

IPC: F02M31/087

Granted: 2021-12-28
Abstract: FIELD: internal combustion engines. 
     SUBSTANCE: invention can be used in internal combustion engines. The method for intensifying the main combustion period is carried out in a diesel engine that has high-pressure fuel lines and nozzles as part of the fuel equipment. The method consists in heating the fuel injected into the combustion chambers to a temperature corresponding to the end of its boiling point. Heating is carried out in a heat exchanger installed on the high-pressure fuel lines at the inlet to the injector. Diesel exhaust gases pass through the heat exchanger. The heating temperature of the fuel, equal to the temperature of the end of its boiling, is initially determined by fractional distillation of the fuel used using an apparatus for distilling oil products. On a diesel engine, the heating temperature is maintained by changing the amount of exhaust gases that have passed through the heat exchanger by means of a control valve using an electronic control system. 
     EFFECT: ensuring complete evaporation in the combustion chambers of the diesel engine and excluding the ignition delay period.
