Inventions of the late XIX and XX centuries.

I did a research about the inventions of the late XIX and XX centuries, what found me more important were the following:

1.- Machine type
2.- Sewing machine
3.- Machine photo
4.- Airplane
5.- Submarine
6.- Bicycle
7.- Electric lamp
8.- Auto
9.- Phone
10.- Movies

Then describe each of them and give you a brief explanation of why I do importante to our life.

Typewriter

It's a machine that prints letters, numbers and other signs when their keys are pressed.

The typewriter was patented as mechanic help for the blind. It`s was recorded in the United States in 1829 by Guillermo A. Burt and was called typography but no model survived.

The first practic typewriter and that could make in large scale was created by three american inventors: Cristobal I. Sholes, Samuel W. Soule and Carlos Glidden.

I think this invention is very important because it was a great ancestor of the computer and in spite of technology we have today and we still use in different areas.

Sewing machine

This machine has revolutionized manual labor in factories and homes, as the seam is a more ancient domestic arts.

The first sewing machine was invented by Englishman Thomas Saint. In 1790 he patented a machine that had manu characteristics of modern sewing chain. This machin was mainly designed to work with leather.

There are a variety of sewing machines, among wichi include special machines for sewing leather, felt hats, buttons, etc. Some machines have more needles and can do a number of parallel seams simultaneously.

Definitely this was a great invention, and that gave us the whole society benefits. Mainly now sewing is easier and takes less time. Thanks to technology, this has been modernized and isn`t necessary to have a big space for it.

Photo machine

The first detailed description of a photo machine century XI. In the XVI the Italian descriptions by Juan Porta and Daniel Barbaro raised great interest in this device, which came into use in various forms purely recreational purposes.

The importance of the photo machine comes with it's application to photpgraphy in the XVIII century. The discovery of a method for light rays forming the image on a surface and left a trail was the initiation of photography as a science. The apparatus used for the fixation of the image taken, of curse, the name of its precedessor.

No doubt that the camera is an essential part in our daily lives allowing us to keep pictures of those beautiful moments or places we visited. Thanks to technology that has made ir easier to transport than can fit in our pocket.

Airplane

Aerial vehicle heavier than air that is used to transport people or cargo. Action moves motoresde propellers or jet, and is supported by the effect of air resistance to certain hard surfaces.

The hombretrató since ancient times to imitate the flight of birds. He thought at first that it was enough to provide themselves with wings and devised machines that were called ornithopters.

None of them gave the desired result, and it was not until the mid eighteenth century who began to build machines capable of moving more air than the equivalent weight, achieving lift off the ground.

But the usefulness of these devices (balloons and airships) is limited. The history of aviation today is that of the aircraft heavier than air.

Fundamentally, the most modern equipment of this type are built based on the same elements that allowed the Wright brothers and Alberto Santos Dumont practical to make the first flight in early twentieth century: wings that support the weight of the aircraft and its cargo, and tail surfaces which serve to give balance and direction. Using appropriate controls are made to vary the position of some surfaces so that the device up, down or turn in one direction or another.



Without doubt the best invention of the century, and that every day has been changing and so has brought us amazing benefits. It is a quick and easy way to get to our destination.

Submarine

Ship built to sail under the water surface, although they also can do at the surface, the use of these vessels is reserved universally navies, they are essentially attacking unit. During the two guerrasmundiales occurred during the first half of the twentieth century submarines of the belligerent countries were actively involved in operations to disrupt maritime traffic. Many merchant ships were sunk, victims of torpedoes fired by submarines and even came to check sinking of large battleships.

The submarine has proved useful to carry out such operations varied. Thus, for example, has played a fleet vanguardiade services, minefields planted in strategic places in the seas, landed sabotage patrols, rescued downed airmen at sea and even made explorations under thick layers of ice in the polar regions.






In the early eighteenth century in England revived interest in submarines and for 1727 had already been patented at least 14, of different types. In an article published in 1747 in revistaGentleman's Magazine, an inventor anonymous suggested the use as ballast water contained in boots made pielde goat filling them with water, submerged underwater, and rose to the surface when it expelled the liquid by a valve at the bottom of the vessel. This idea is basically the same applies today in the construction of submarines that carry ballast tanks.

The difficulties to solve the many problems of hydraulics and mechanics, together with the rooted general conviction that the submarine would never be a practical means of navigation, were due to slow its adoption by the navy for at least another 100.

Electric Lamp

When primitive man began to make use of the fire was soon burning discover that some substances than others. A pine knot, for example, was burned well and bright light. When placed chops noted that the fat droplets sparkled brightly in the flames.
Probably this observation came the idea of making a lamp. Stones found in a similar way to dishes, filled them with melted animal fat and devised a wick or wick made of moss or similar materials.
The wick was soaked in melted fat and burned with a weak flame and smoking.
The Eskimos still burning, for light, seal blubber in flat containers of stone.
The earliest lamps were to shallow dish in aceiteo burning fat. Inside the houses did not need protection from wind and rain the flame of the lamps. But when he drew the outside it was necessary to place them in containers that guarded the flame from drafts. These protective containers should have holes or windows that let light through so that the lamp continue to fulfill its purpose of lighting. Thus was born the lamp: it was a flashlight likely be removed or outdoors without being extinguished.
The fat and oil lamps were improved slowly, as they discovered better fuels. It is refined animal fat, were hunted whales for lamp oil, was used vegetable oils, like olive oil and, finally, were used in the mid-nineteenth century, oil and some of their products. Which is more widespread of these was the kerosene.
Among all available media that the man of the past he used for light perhaps none was more important than sailing. They made candles from animal fat that was put around a wick. Tallow was a fat favorites. Then he warned that burning beeswax better, but had the disadvantage of being scarce and expensive. Later he turned to the paraffin, a petroleum product. The candle was also used as light source in the headlights.
