A razor is a device that holds a razor blade while shaving. At the same time, for safety, the edges of the blade only protrude slightly from the machine.

The classic razor with a replaceable double-edged blade, invented by Gillette, is still in production and is quite popular due to the low cost of the blade as a result of its standardization, relative simplicity and long service life associated with the ease of complete cleaning of hair residue and moisture.

Machines with interchangeable multi-blade heads have non-uniform mounts for movable or fixed fixation of shaving heads. The heads contain a variable number of blades (from two to five or six) and sometimes a moisturizing strip to soften the hair. The disadvantages of the design include non-standard heads tied to a specific machine, higher cost and laboriousness of cleaning the blades from hair residues and moisture.

We can say that King Kemp Gillette, born in 1855 in the town of Fond du Lac in Wisconsin, inherited a love of invention. His father was a jack of all trades and worked as a patent attorney. King's mother was also an inventor - in the field of cooking: her cookbook, first published in 1887, is still being reprinted.

At 17, King Gillette became a traveling salesman. At the same time, he did not forget about inventions: by 1890, there were already 4 patents in his "portfolio" (although he had no benefit from them). Looking at this, William Painter, inventor of the disposable bottle stopper and founder of Crown Cork & Seal Co, for which King Gillette worked, gave him good advice. "If you want to make a profit by selling a product you have invented, invent something disposable. Then, if the product is successful, satisfied customers will be forced to contact you again and again."

The work of a traveling salesman is associated with constant traveling, and Gillette often had to shave on trains. It was very risky: because of the shaking at the junctions of the rails, a straight razor could easily cut your throat. Gillette used a Star Safety Razor razor, made in the manner of a chopper: the handle was fixed perpendicular to the massive blade. The razor quickly became dull and had to be sharpened frequently.

In 1895, Gillette came up with a simple idea: to use thin steel strips instead of a massive blade, which, if the sharpness was lost, could simply be thrown away.

With this idea, he approached the metallurgists of the Massachusetts Institute of Technology (MIT), and they assured him that it was absolutely impossible. But Gillette did not give up and, together with the engineer William Nickerson (ironically, an MIT graduate), for six years he developed the design of a razor, blades and the technology for their production. Gillette and Nickerson founded the American Safety Razor Company in 1901 and began mass production two years later. Moreover, in order to form a market, at first they even had to sell goods at a price below cost.

In 1904, King Kemp Gillette received a patent for his invention, and the company was renamed the Gillette Safety Razor Company. After that, a strong half of humanity recognized the inventor of the razor not only by name, but also by sight: a portrait of King Gillette was printed on each package with Gillette blades.

Gillette died in 1932 before the introduction of the electric razor.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Mini power station for charging gadgets 26.11.2013

Scientists from the Tomsk University of Control Systems and Radioelectronics - TUSUR have developed a small power plant controlled by a special controller that allows charging mobile devices in places where there are no electrical networks.

The development is a furnace with a volume of 1 cubic meters. m., which can be heated with various organic fuels: firewood, charcoal, sawdust, wood chips, peat and even sunflower husks. As a result of incomplete combustion of fuel, gas is produced on which the engine runs.

Similar power plants existed before. The fundamental difference of the new development is that the resulting gas does not contain impurities and resins, so the engine life is significantly increased. It also prevents harmful substances from being released into the atmosphere.

Uninterrupted operation is ensured by the controller. Such power plants can be used, for example, by teams picking mushrooms, cones and berries in the forest: they can charge mobile phones and radio stations, dry clothes, power freezers for shock freezing.

Another advantage of the new power plant compared to analogues is the rather low cost of electricity generation: 1 kWh will cost about 2 to 12 rubles. depending on the cost of fuel. For comparison: the cost of 1 kWh produced by a diesel power plant can reach 120 rubles.

By the beginning of summer, it is planned to release 2 industrial units with a capacity of 15 and 25 kW, respectively, and also to prepare a technology for small-scale production. The plant will be able to produce from 5 to 15 such power plants per month. It is assumed that the cost of one gas generating station with a capacity of 15 kW will not exceed 600 thousand rubles.
