In the old days, many people knew how to sharpen braids, although this is not an easy task: before bringing the blade to a ringing sharpness with a whetstone, it was beaten off with a special hammer on a rounded anvil. Now, few people know the art of beating. And you should. For example, in the collective farm "Progress", sponsored by our KYUT, at the time of haymaking on the edges of the forest and other places inconvenient for cars, the grass is mowed by hand. Of course, there are a lot of braids, and there are only a few old people who know how to beat them off, they do not have time before the new dawn, and collective farmers turned to us with a request to help mechanize this process.

With the head of the club, V. M. Nebozhak, we came up with the SKK-1E - a machine for riveting braids, electric. An IZ 5402 electric cutter was used as a drive. It was installed (in place) on a body welded from two sections of a channel and screwed to the frame. The working body of the machine - a hardened steel striker - was attached to the movable drive element.

An anvil was placed under the striker. Unlike what we are used to, it is not a massive piece of metal, but a rather complex device that allows you to adjust the gap between the surface and the striker. This makes it possible to accurately dose the force of impacts.

The anvil has an axis of rotation and a spring-loaded adjusting bolt. Under the nuts, a washer made of dense rubber is put on it so that it does not rattle in operation.

Machine SKK-1E (click to enlarge): 1 - electric drive, 2 - insert, 3 - striker, 4 - stop, 5 - anvil, 6 - body, 7 - anvil axis, 8 - frame, 9 - spring, 10 - rubber washer, 11 - adjusting bolt, 12 - angle

Behind the striker, a stop was welded to the anvil, limiting the depth of inclination on the blade, and to the bed - a corner with holes for the mounting bolts so that the machine would not move along the workbench from vibration.

The beaten scythe is held with both hands with the blade away from you. Bringing it under the jumping striker, slowly move it from right to left. Final fine-tuning with a whetstone.

Now the spit is not afraid of a stone. If something happens, it can be put in order on the quickly and accurately working SKK-1E

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Ultra high speed liquid crystals 20.08.2013

A group of American researchers from the University of Kent was able to increase the speed of liquid crystal control by orders of magnitude. Physicists have found a way to shorten the time it takes for molecules to return to their original state after the electric field is turned off. This process, instead of one millisecond, now takes only about 30 nanoseconds.

The scientists used a new method of changing the molecular structure of liquid crystals under the action of an electric field, and also abandoned the control of transparency by rotating the plane of polarization of light. Instead of rotating all the molecules at once and turning the plane of polarization, physicists changed the mutual orientation of the molecules, the shape of which, in the first approximation, is a flattened ellipsoid. Such ellipsoids in the absence of an electric field are already "slightly" ordered, and its inclusion leads to the fact that the ellipsoids are stacked and the degree of ordering increases sharply.

Having assembled a pilot setup from a laser, several polarizers and an experimental cell with liquid crystals, physicists showed that the increase in ordering leads to the fact that when light passes through the cell, the effect of birefringence is enhanced. Rays of light with different directions of the polarization plane diverge more strongly in different directions, and this effect can already be applied to control transparency using polarizing filters. This method, as the authors emphasize, does not make it possible to make the cell absolutely opaque, but the head of the research group, Oleg Lavrentovich, believes that the method can be significantly improved.

Cells that rotate the plane of polarization are at the heart of all modern LCD technology. Liquid crystal molecules can either move from a mixture of two mutually perpendicular states to a state when they are oriented in one direction (TN technology), or simply rotate 90 degrees (IPS, VA and derivatives) in one of two independent layers. The turn of molecules when the field is turned on is very fast, but when the field is turned off, the transition to the initial state takes at least one millisecond.
