"Ten Inventions of Century"

"Inventions of the nineteenth century"




Locomotive: Since its inception in the early nineteenth century to the mid-twentieth century, steam engines were. The first steam locomotive was built by George Stephenson in 1812 in the mines of Pen-y-Darren in Gales.1 Until 1825, the use of steam locomotives was exclusive of railways in coal mines.




Photo: In 1816 Niepce obtained a first negative image is imperfect and unstable, with a pinhole camera. In 1826, gets its first blueprint, based on the bitumen or asphalt.
Louis Daguerre is associated with Niepce, for further investigations. But Niepce died in 1833, and Daguerre continued alone until a reliable and commercial. The daguerreotype was introduced in 1839 at the Academy of Sciences and Fine Arts of France.
Anesthesia: Later, on 16 October 1846, in Boston, was William Morton, Wells' assistant, who conducted a successful demonstration of the use of anesthesia when applied to a patient of Dr. John Collins Warren. Dr. Warren was able to remove a tumor from the neck of a patient without that feel pain. Since then, Morton was devoted to anesthesia, hiding the type of gas used (which he called "letheon") to use exclusively, but was forced to reveal that it was ether. Since then, the use of Ether spread rapidly.
Incandescent lamp: The invention of the incandescent lamp is generally attributed to Thomas Alva Edison presented the October 21, 1879 a practical and viable lamp, which she wore for 48 hours straight. On January 27, 1880 was granted the patent, numbered 223,898. Other inventors had also developed models that worked in the laboratory, including Joseph Swan, Henry Woodward, Mathew Evans, James Bowman Lindsay, William Sawyer and Humphry Davy.
It is recalled that the German, Heinrich Goebel had already registered its own incandescent light bulb in 1855, long before so that Thomas A. Edison. Some time later, but before that, Edison, 11 July 1874 he was awarded the Russian engineer Alexander Lodiguin Patent No. 1619 by an incandescent bulb. The Russian inventor used a carbon filament.



Airship: In 1863, Solomon Andrews devised the first fully steerable airship, although he had no motor.




The Vitascopio, originally called Fantasmascopio, is a film projector was first exhibited in 1895 at the Exhibition of the cotton States in Atlanta, Georgia, USA. Its creators were Charles Francis Jenkins and Thomas Armat. Issued without intermittent succession of images on a wall or screen for a considerable amount of public. The economic success that generated the first projections generated a conflict between its creators, who began fighting on the credit of the invention.
Armat, who had legal rights Fantasmascopio sold the company that produced the Kinetoscope. This company realized that his Kinetoscope soon be obsolete compared to the rapid advancement of film engineering.
Thomas Alva Edison reached an agreement whereby Edison Armat was considered the inventor of Fantasmascopio, which has since become known as Vitascopio.



The photo-phone was a device that allowed sound transmission through light emission, invented by Alexander Graham Bell in collaboration with Charles Sumner Tainter. The device uses light-sensitive cells made from selenium glass, one of its properties is that the electrical resistance varies inversely with the lighting. The basic principle was photophone modular light emission directly to the receiver, manufactured in selenium, which was where a phone was connected. The modulation was made by a vibrating mirror or a rotating disk that periodically darkened the light beam.



The Gramophone (Greek gramma phones writing and sound) was the first system of recording and reproducing sound that used a flat disk, as opposed to that recorded on a cylinder phonograph. He was also the most common device for playing recorded sound from early 1890 until late 1980. It was patented in 1888 by Emile Berliner.




Air: The first plane itself was created by Clement Ader, on October 9, 1890 to take off and fly 50 m. with Éole. Subsequently repeated the feat with Plane II flying 200 m in 1892 and the plane flies III in 1897 over a distance of 300 m. The flight was the first flight Éole propelled the history of mankind, and is considered the starting date for aviation in Europe.




Bibliography:

















Phone: Already in 1854 the French inventor Charles Bourseul raised in a pictorial of the time the possibility of using vibrations caused by the voice on a floppy disk or diaphragm, in order to activate and deactivate an electrical circuit and produce a similar vibrations in a diaphragm located in a remote location, which would reproduce the original vibration.
Some years later, German physicist and professor Johan Philipp Reis invented an instrument that transmitted musical notes at a distance, using electricity, but this was not able to reproduce the human voice.

  1. hi phan wow your blog it's really this very complete i like so much that is informaion very important to know that times have been developed some of the things we use today is very interesting to know that i believe in the nineteenth century as it was the anesthesia and know their origins also know that what was the focus incandesente attributed to him to edison was not entirely by the that we have the current truth seemed to me very interesting topics that published in your blog.
