Technological Advances

The changes caused by the Industrial Revolution were irreversible and definitely modified the social and economic structures (since the “ancient” regime). The first revolution was the technologic; it introduced the use of industrial machinery productive processes.

You will need to answer the following questions:
1. What changes caused the industrial revolution in the Britain society?
2. What was the importance of steam engine in that revolution?
3. What inventions were developed during e Victorian Times?
4. Give a description of the steam engine:
a. How it works
b. Components
5. What improvements were introduced by James Watt to the steam engine?
6. What was the utility of the slide valve?
7. What was the usefulness of the centrifugal governor?
Leave your comments and justify your answers.

    The slide valve:
    The slide valve is a rectilinear valve used to control the admission of steam into, and emission of exhaust from, the cylinder of a steam engine. This was used in the locomotives and in the steam engines.
    They were relatively simple to set up, easy to maintain and lasted for a long period with minimal maintenance.
    In nineteenth century the principal use of slide valves was control the flow of steam into and out of the cylinders. The steam pushes the piston bakward and forwards to obtain a continuous rotary motion to the crank.

    The steam engine is a heat engine that performs mechanical work using steam as its working fluid. They’re external combustion engines which transforms the thermal energy into mechanical energy.
    Water turns to steam in a boiler and reaches a high pressure. When expanded through pistons or turbines, mechanical work is done. The reduced-pressure steam is then released into the atmosphere or condensed and pumped back into the boiler.
    Components
    The steam engine is composed of different parts, without which they couldn’t work:
    -Boiler: Boilers are pressure vessels that contain water to be boiled, and some kind of mechanism for transferring the heat to the water so as to boil it.
    -Inlet and outlet valves: it lets the water to get into and out of the cylinder
    -Entry valve: it lets the vapour to get into the container. If it closes, the supply of vapour shuts.
    -Container: it contains the slide valve.
    -Slide valve: it regulates the entry and exit of the vapour in the cylinder. It moves to the left and the right and it connected to the rod.
    -Cylinder: it’s a cavity with two holes, to let the vapour get in and out. It contains the piston.
    -Piston: it’s a disc which occupies the cylinder and it’s traversed by a bar in the middle. This bar connects the piston.
    -Exchange system of slide valve: is made of cranks connected to rod of the slide valve.
    -Rod: connects the piston with the crank.
    -Crank: connects the rod to the flywheel. It transforms, with the helps on the rod and the flywheel, the alternative lineal movement into rotational movement
    -Flywheel: maintains the rotational movement for its inertia.

    The steam engine was created by James Watt, its importance is that it could adapt to any other which had the advantage that allowed the installation of industries in areas where coal could be obtained cheaply.Established new working relationships, there were big business and formed a large proletariat laborer. Allowed to continue with technical advances aimed at improving the production and distribution of goods and services.
    This machine was very important at that time because it gave many people a job and all the people came to lock the city. This machine facilitated the work of many people of that city. The steam engine was a great step forward in society.
    During the Industrial Revolution, steam power began to replace water power and muscle power (which often came from horses) as the primary source of power in use in industry. Its first use was to pump water from mines

    A centrifugal governor is a specific type of governor that controls the speed of an engine by regulating the amount of fuel (or working fluid) admitted, so as to maintain a near constant speed whatever the load or fuel supply conditions. It uses the principle of proportional control. This governor was created by James Watt. This term is dificult to understand and I propose to view a video to understand it better:

    What changes caused the industrial revolution in the Britain society?

    • The population could travell to other places.
    • They where big changes in the imports and exports.
    • Thanks to the transport the population could pass the holidays in a city with sea.
    • It cause a big demographic revolution.
    • This can advance in the medical investigation and thanks to this advances the mortality decrease.
    • The population increased so much and it caused demand in the housing and the alimentation.
    • The population and the countries could had drinking water and gas, and in the final of the XVII century they finally achieve to have a electricity.

    An important development was the improvement of communication (stagecoaches, canals, steam ships, trains, and railways).
    – The first electric train was invented in 1879
    One important invention in communications was the Penny Black, the first postage stamp.
    Other type of communication like cinema, telephone, telegraph, telephones, cars and aircraft had an impact for people.
    – The electric telegraph was developed by William Cooke and Charles Wheastone in 1858.
    – The telephone was invented in 1876
    – Guglielmo Marconi discovered the radio in 1895
    The Victorians were impressed by science and progress, and felt that they could improve society in the same way as they were improving technology.

    A Scottish mechanic named James Watt (1736-1819), realized that the performance of the Newcomen engine wasn´t satisfactory. To repair a Newcomen engine he introduced important modifications. Causes the vapor to condense into a special container, the capacitor, which connects to a cylinder tube which also closed at its two ends. This could keep the cylinder always hot, saving significant amount of fuel. Wattson also introduced other improvements in the machine, as a mechanism to regulate the distribution of steam: double engine.
    The false idea of ​​considering Watt as the true inventor of the steam due to the large number of contributions made ​​to his improvements. He invented the ball or centrifugal governor in 1788 and the power unit watt (watt) was named in his honor. In 1767 he invented an accessory to match the telescope that was used in measuring distances.
