Chapter 49: Serious Business
After the speech, the students and ladies who were so moved began to enjoy a sumptuous Christmas dinner, and the band invited by the high price played cheerful music on the side, and the atmosphere was very good.
When everyone's feast was almost done, it was finally the turn of the finale of today's Christmas dinner, and Mr. Babbage was the host of the show.
Some of the students had already guessed a little bit about Mr. Babbage's computer! Babbage's failed machine made a total of 28,000 parts, and this time, Downing's acetate thermoplastic factory made more than 300,000 Lego-style parts for him, and the thermoplastic model is there, ready to be produced again according to the progress and needs of the project, what he wants, as much as he wants, and let Mr. Babbage's imagination run wild to build the world's first programmable computer.
Professor Babbage was the chief engineer and divided the project into more than a dozen parts, led by a dozen of his assistants, and organized volunteer students from Cambridge University to accomplish this feat. But any student who can understand the principles of this machine can join in this historic event. Downing provided funding and spare parts production for the project, and served as a consultant, and he loved to do what a local tyrant should do - what scholarships and employment opportunities were used to attract students to volunteer.
Attentive students may find that the quality of the materials they receive is not very good, and it turns out that it is produced on a small batch of mimeographing machines. Typewriters with paper tape transit do have a "copying" function, but this speed is too slow, and you have to wait for dozens of copies to be copied seriously. As a result, the telegraph subsidiary printing house, which had been officially renamed the "Three Primary Color Printing Factory", developed this mimeograph machine. It is a template that produces a mimeograph by carving a pattern on the wax paper so that the ink can be immersed and removed. This wax paper can be engraved by hand or with a special chiseled wax type.
The mimeograph machine uses quick-drying ink, and there is a heating process at the end, so that the finished product is completely dried without dirty hands in the first time. Professional copying can be made by means of a special plate-making typewriter, which will be a very popular low-batch printing machine, especially suitable for printing temporary materials for students, a total of dozens of copies. If the amount of more than a few dozen copies will become blurry, it is important to use a plate-making typewriter to remake the plate, in this way, it is easy to print dozens to hundreds of copies, or even thousands of copies of the exact same material in extreme cases.
Downing's products in the office sector are becoming more and more abundant, and this suitable administrative and public mimeograph machine costs £120 a year, but it is designed to require electric motor transfer and heating, so it is not yet on sale. Soon after the Sewerage Commission decided not to reserve space for underground cables, Downing had no choice but to increase the space he wanted for the sewer project at his own expense, but in this way, the right to use this space would belong to him in the future, or let him monopolize London's underground cable network, if others wanted to build such a network again, the cost would be high, and Downing would now dig sewers and start the project to take advantage of the bigger, of course, even if someone was greedy at that time, it was useless. The sewer was originally started after Downing donated £1.5 million, so it was natural to take advantage of it.
After nearly a year of research and development, Faraday Power's initial power system, wind turbines, cables and wires, inverters, rectifiers, transformers, sockets, AC motors have solutions, and the power network in the City of London and Westminster is under construction, and London is about to usher in the electric era. The most important application in the electric era is lighting, and during this time, the "General Electric Company" established by Downing is also nearing the end of integrating all aspects of the light bulb, including the control of tungsten ore, filament production line, glass cover production line, nitrogen separation process to prevent tungsten filament oxidation, lampshade design, etc.
Among these links, the separation of nitrogen is the most important. Nitrogen is an inert gas and is abundant at 78% in the atmosphere, followed by oxygen at 21%. The separation of these two gases is of the utmost importance.
Many people know that activated carbon can be used to adsorb impurities in gases, and an engineer named House in the London Sewerage Commission proposed to use activated carbon to absorb impurities in water vapor and gases. Carbon molecular sieves can also be used to separate air, the secret lies in the pore size of carbon molecular sieves, when it is between nitrogen and oxygen and close to the diameter of the gas molecules to be separated, the diffusion rate or adsorption rate of the mixed gas in its pores is different, so as to achieve the separation of gases.
There are many raw materials for the production of carbon molecular sieves, such as coal, resin, husk and kernel, and the resin with a relatively single composition is the best raw material for the manufacture of excellent molecular sieves. Carbonization is the key to the formation of pores, which is the process of heating raw materials under inert gas conditions to make volatile substances, i.e., small molecules, escape from the molecular pores in the carbonaceous material matrix, forming pores and increasing the surface area. The main factors affecting the carbonization process are the heating rate, carbonization temperature and constant temperature time. Using resin as raw material, when the temperature is controlled at 500 to 1100 degrees, and the heating rate is less than or equal to 10 degrees per minute, 0 can be obtained. 3 to 0. The 6nm carbon molecular sieve has a good separation effect on nitrogen and oxygen.
Pure oxygen, a by-product produced by carbon molecular sieves, is an important welding and metal cutting gas with acetylene.
Getting back to the point, using Lego bricks and group cooperation to build a machine can be regarded as greatly reducing the difficulty of the project, since then, Babbage no longer has to worry about his changing minds, parts production and reorganization are not a problem, it can be said that Associate Professor Tang Ning helped him solve the biggest engineering problem, and the use of this production method has also clarified a lot of ideas for Babbage. Each group can even build the parts according to their own way of thinking, as long as the result is in line with the machine principle. The crowd gathered firewood and the flames were high, and the Cambridge students were often able to come up with a solution that would go beyond Babbage's original vision, making the machine faster and lighter.
Today is only the first exercise of this engineering method, and the busy students have shown their own ingenuity and hands, which has given Professor Babbage unprecedented hope.
That's what Downing was doing with the Cambridge students.
Most of the lovers of literature and art from Little Holland House naturally don't know the principle of this machine, and it is difficult to understand it, but they also know the great technical and engineering significance of this machine, which can actually free humans from calculation. There was a girl who was even looking forward to the future when people would not have to study mathematics, and she was ridiculed by everyone.
The psychological impact on Countess Eugénie tonight is quite large, even Louis? Napoleon's ascension to the throne as emperor was only a man who changed France, and the extent of this change was not large, this little baron was a man who changed the world, and he was so young and handsome...... The most regrettable thing is that it seems that the little baron is more interested in technology than beauty, and it is estimated that like Louis, he will not easily propose to others, but she can feel that the little baron has a very subtle affection for her.
