Today, internal combustion engines are so accessible that hardly any of the professionals would think of designing low-speed wave engines. But fans have their own reason. Sailing yachts still sail the seas. No one considers oar boats, kayaks, boats obsolete. So why not build a boat that uses free wave energy for movement?

Observe how a wooden stick behaves when thrown on the surface of the water. She rides the wave. If one of its ends is oriented directly to the wave, then it experiences, as sailors say, keel rolling. A wave hitting the side causes the stick to rotate around its own axis. This is the so-called roll. Inventors pay attention to these fluctuations. Is it possible to use their energy for movement? Many ideas and proposals were expressed. We have already talked about some of them on the pages of the magazine. Today we offer to experiment with a specific wave engine. Its author is Jerol Limelson.

As you can see (see diagrams 1-6), the main part of the engine is a swinging balancer, resembling an inverted pendulum. There is no excitement on the water - the balancer occupies a strictly vertical position and the engine does not work. There is a wave - the balancer begins to swing in time with it.

The balancer swayed to one side, then to the other... The magnitude of these oscillations depends on the mass of the load at the upper end of the balancer and the steepness of the wave. The product of the force on the shoulder is the moment of force that can already be used to rotate the propeller or wheel. True, in such a mechanical converter, such a circumstance must be taken into account. In order for the wheel or screw to rotate only in one direction, a ratchet mechanism must be provided in the mechanical transmission.

And now let's see how Limelson managed to realize his idea. Figure 7 shows a model using pitching. The balancer with a massive load at the upper end has the ability to swing relative to the lower point. Its handle has a groove along which the upper end of the lever moves freely. The lower one is rigidly connected to the bevel gear. As you can see, this part of the mechanical transmission converts the reciprocating movement of the balance bar into the rotational movement of the output shaft. The second bevel gear increases the speed of the output shaft, which significantly affects the speed of the model.

In principle, this mechanism can be used to drive the propeller and roll. It is only necessary, as the inventor suggests, to turn the plane in which the balancer swings by 90 degrees. How to do this using the same gear engagement, we suggest you guess for yourself. Therefore, we will not dwell on this.

Limelson proposes a more interesting and at the same time more complex solution for the use of rolling in a mechanical converter shown in Figure 8. As you can see, here the balance bar swings not in a vertical, but in a horizontal plane. It is difficult to say what advantages such a mechanical system provides. Only experiments with working models will be able to clarify them.

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 ... >>

Danger of anticonvulsants 14.07.2018

Anticonvulsants are increasingly being used to treat low back pain, but a new Canadian Medical Association Journal study shows they are ineffective and may have adverse effects.

"Clinical prescribing of anticonvulsants for back and neck pain, including radicular pain, as primary health care has increased by 10% over the past 535 years," writes Dr Oliver Encke of the University of Sydney and Nepean Sydney Medical School (Kingswood, Australia), citing data from a recent study of the most common medical prescriptions for back pain.

Low back pain affects millions of people and is the number one cause of disability. Clinical practice recommendations generally include non-pharmacological treatment and non-opioid pain medications rather than stronger analgesics such as anticonvulsants.

The results of the study are based on data from nine studies, revealing a lack of evidence for the effectiveness of anticonvulsant drugs and indicating side effects from some of these drugs.

"We have shown that conventional anticonvulsants are ineffective in chronic and radicular low back pain and are associated with an increased risk of side effects," the authors write.

These results support recent recommendations from the United States and the United Kingdom to limit the use of anticonvulsants.
