The diagram of a portable device for electric sleep is shown in the figure.
(click to enlarge)
The device can be used both in stationary and outdoor conditions with a 9 V battery. The device consists of a blocking generator made on V1 P216 transistors (with any letter index) and a pulse transformer. The generator frequency can be changed by resistor R2 within 1-500 Hz, and the voltage and current acting in the circuit can be changed by resistors R7 and R8, respectively.
The device uses an ammeter with a scale of 1 mA. The transformer is made on a permalloy core with a cross section of 3 cm2. Winding I contains 86 turns of PEL 00,6 wire, winding II - 55 turns of PEL 0,3 wire, winding III - 980 turns of PEL 0,1-0,12 wire.
Headphones can be connected to the device, which sometimes enhances the effect of electrical impulses on the patient in the treatment of insomnia and certain types of neuroses. The current value is selected in the range of 150-250 μA at a voltage of 1-16V, the pulse frequency is 1-200 imp/s, and a high frequency is used at the beginning of the session, then gradually decreases to the patient's pulse rate. The combined use of several influencing factors (imitation of surf noise, metronome sound signals, as well as potassium and bromine ions) significantly increases the effect of electrosleep.

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 ... >>
| Random news from the Archive Plastic gears instead of metal ones
07.05.2015
Gears made of carbon fiber reinforced plastic can replace the usual metal gears in car assemblies.
Considering the amount of torque and power required to propel a car weighing more than a ton, it can be assumed that plastic gears will be destroyed within a couple of minutes. However, scientists from Gifu University (Japan), together with specialists from Central Fine Tool, have developed a carbon fiber reinforced plastic gear that is strong enough to replace metal parts in vehicles.
A thin layer of carbon strengthens and strengthens the gear teeth, besides, such made have significantly less weight, which means they make the car lighter and improve its fuel efficiency. Plastic gears are much cheaper to produce than their metal counterparts. Japanese engineers hope to put their development into production by 2017, finalizing and improving the design of gears.
This is not the first attempt to use plastic in the construction of automotive units - German engineers recently proposed making an internal combustion engine cylinder block out of it.
