Five Romanian inventions that changed the world

Romanians have a huge potential for intelligence. Evidence in this respect is the gold medals that the inventors of our country have obtained each year at the big salons of invention.

The concern for the new has always been in the attention of the Romanian scientists. Some of them have entered history, their inventions saving millions of lives.

Here are five of the most important inventions of some Romanians.

1. Antichlear vaccine - Ioan Cantacuzino
Professor Ioan Cantacuzino (1863-1934), one of Romania's most illustrious scientific personalities, is among the creators of Romanian experimental medicine, founder of the Romanian microbiology school. His findings have been particularly important in the treatment of cholera, typhus epidemic, tuberculosis and scarlet fever.

The doctor has developed a method of anti-holocaust vaccination, also used today in countries where cholera cases are reported. In 1913, he led the first massive anti-holocaust vaccination in infectious outbreaks, known in science as "The Great Romanian Experience," which saved thousands of lives.

The discovery of this vaccine, which was so necessary at the time, was the culmination of the career of Dr. Ion Cantacuzino, although his work had other remarkable results. He also studied active immunization against dysentery and lymphocytic fevers, etiology and pathology of scarlet fever.

2. Reacting plane - Henry Coanda
In October 1910, the Grand Champs-Elisee Palace in Paris hosted the second edition of the International Aeronautics Exhibition. The newest pieces of aviation were exhibited. The most interesting machine was a red, non-propeller plane, on whose pleasing metal she wrote: COANDA-1910. This plane has raised interest not only because it did not have a propeller, but because it was totally different from what they called "airplane" so far. The machine had two double wings and a single seat, a 10.3 m long, 12.5 m long, 420 kg weight, and a 220 kg propulsion force. The most interesting part of Coanda's plane was the propulsion system, a real revolution in aircraft engine construction, which would be the solution to the future.

The Reaction Engine, invented and built for the first time by Henri Coanda, consisted of a water cooled, four-cylinder piston engine that developed 50 horsepower at 1000 revolutions per minute. This piston motor was connected to a rod rotating the rotary multiplier; The movement was transmitted to the compressor that earned a rotation of 4000 revolutions per minute. The propulsion power was 220 kgf, much higher than if the piston engine was connected to a propeller. Many visitors to the exhibition were suspicious of the take-off of the plane, until an accidental demonstration of Coanda, when, just wanting to check the engine, the plane started to go faster and faster until it flew. Impressed by engine flames and worried that he had not flown a plane by then, but only gliders, Henry lost control of the machine, which had lost in height and speed until it landed forcefully. This was the first flight with an airplane equipped with a reaction engine. Thus, 30 years before Heinkel, Campini and Whittle, Coanda built and flew the first reaction plane.

3. The Pen - Petrache Poenaru
One of the Romanian scientists of lesser known but undeniable value on many levels is Petrache Poenaru (1799-1875).

In the history of universal invention, Petrache Poenaru is known as the creator of the first helmet with a pumpkin, known at the time as the "stylograph". At only 28 years, Petrache Poenaru patented the world's first tank of water, first in Vienna, then in Paris in 1827 (when he was a student), titled "Endless Portraits, feeding himself with ink" The holder of the first patent obtained by a Romanian.

The patent of invention shows not only the inventive spirit of the Romanian student, but also the originality of the concept, as simple as practical. Petrache Poenaru's invention revolutionized the field of writing tools, thus contributing to the creation of an object that today is used by billions of people.

4. Cybernetics- Stefan Odobleja
What is technology nowadays is largely due to a little-known man in Romania: Ştefan Odobleja. He created the concept of cybernetics. This talks about backward control, and the term has mostly spread to digital systems, but is not limited to that.

Cybernetics deals with how a system processes information and responds to it. Cybernetics also studies how systems change or allow changes to optimize their actions. Doctor Stefan Odobleja is the creator of generalized psycho-cybernetics and cybernetics, and in 1929 he wrote about the Method of Thoracic Transonance in which he also enacted the Law of Reversibility. In 1937 he also announced his main work: Consonant Psychology, making public the first version of the generalized cyber conception, and demonstrating its multidisciplinary character.

5. The ejectable chair - Anastase Dragomir
At the end of the 19th and early 20th centuries, most aviation experts were concerned about airplanes and their pilots. A Romanian youngster named Anastase Dragomir focused on the safety of flight machines and, implicitly, on their passengers, by improving their own system for rescuing pilots and passengers in the event of accidents.

This invention was "a new parachute system for airborne locomotives, each passenger having his own parachute, which at the critical time allows the release of this airplane assembly so that the parachute, together with the passenger installed in the seat, pass through a Opening of the floor. "The patent provided that this parachute-cell assembly had several controls, maneuverable by the pilot.

In 1950, Anastase Dragomir obtained a new patent, this time in Romania, for the "parachute cell", which consisted in the use of a curved sliding back for the ejection of the cabins either on the floor or on the top. Demand for the construction of an airplane with such seats.
