The British telegraph company was divided into three parts, one was to establish a global telegraph network, and the other was to rent telegraph machines for 100 pounds per year, and typewriters without telegraph function for 80 pounds, which was a very strange marketing method at the time, but the shareholders did not interfere with the behavior of President Downing, because it was a trivial matter, and it was better to go another way. The third is to sell consumables such as paper tape, ink, batteries, etc. As for the navigation function, it will be more convenient to wait for the establishment of the global telegraph network before developing it.

As they recruited staff, trained them, and established a global telegraph network throughout Britain and the colonies of the British Empire, and on the European continent, the world-renowned Universal Industrial Exposition began.

This unprecedented expo officially claims to have a total of 13,000 exhibits, and there is a jacquard machine that greatly improves the efficiency of the textile, in fact, the paper belt technology is used in the Jenny spinning machine, not a black technology, some people even say that the Jenny spinning machine is the beginning of the industrial revolution. There are also envelope making machines, kitchen supplies, harvesters, which are machinery from the United States and symbolize that the United States will embark on the road to a modern agricultural power.

There was also a locksmith named Hobbes from the United States, who brought new locks to the Dae Newell company that made locksmiths all over Britain ashamed. Tang Ning was very interested in the new lock, because with more and more information about the real room and the factory, and more important documents, he hoped to have a huge combination safe, which was fireproof and anti-theft, which would be of great benefit to the development of his business. In these years, there was no electric light, and when it got dark, it was lit by an open flame, and the fires were quite frequent, and maybe one day his work would be ruined, which was something he never wanted to happen.

Due to the huge amount of their own information, there are still a lot of paper tapes to be kept as documents, it is conceivable that if thousands of boxes are used with traditional keys, the warehouse manager must not be tired to death, and need to produce the power of invention and creation, and the god of Tangning is ready to develop a combination lock. This time, he was going to hand it over to the craftsman named Hobbes, who had demonstrated his skill at breaking the unlock at the fair, (the challenge lock called Brahma had been challenging humans for 67 years, and it took Hobbes 16 days to get it done, winning the £200 prize), which sparked onlookers and a conversation with Downing who admired his craft.

Downing returned home and began to tinker with its boxy cabinet design with no weak points, and the key to opening it was only eight pairs of gears made of pure iron, one of which had 26 English letters on it, and its arrangement was more than 60 billion kinds, which was theoretically impossible to crack. The use of letters instead of numbers can effectively improve the user's memory.

The locker is divided into two levels, one is the main level, which can open the main switch and operate all the boxes, and the other is the operator level, which can only open one safe.

Hobbes, who has always regarded himself as a skilled craftsman, first felt that he was unaware when he saw the design of the combination lock, and then when he heard Downing casually say the number 60 billion, he felt even more profound. It turned out that he was triumphant after being talked about by the people of the world, and it took him a whole week to figure out this design - high, really high! served. This craftsman, who is still working for others, is preparing his own Hobbes? Hart & Company, at this time, moved the mind of Downing to join the house, and felt that this combination password safe was very interesting, and completely changed the design concept of the super-large combination safe. This is also a talent, Tang Ning agreed to join the gang, his payment is the design patent of the combination lock and a thousand pounds, this craftsman and his little friend Hart are not particularly rich, and the family is not as rich as Tang Ning, so they will not take advantage of them.

After happily negotiating the deal, Downing relaxed and returned to his booth of the British Telegraph Company, which was with the East India Company, which was bustling with visitors marveling at the ingenious typewriters and wireless telegraphs.

When Downing appeared, the guy in charge of the stall, a clever apprentice he had newly hired, immediately stood up and introduced everyone to the great inventor who had become a blockbuster. Everyone looked at each other with admiration, and the words of praise such as "amazing" and "unbelievable" were endless, this feeling was very good, Tang Ning smiled, and the hard work of these days has been rewarded.

An English physicist with a mustache held out his hand and begged for a relationship, saying, "Hello, Mr. Windsor, I am Bakewell from Wakefield, West Yorkshire, and I have an invention that is somewhat similar to your great masterpiece - the fax machine, which is still in the stage of the real room, and I ask for guidance!" ”

Oh, it's really a master, my old man didn't expect that someone would rush to build a fax machine in front of me? I want to see and learn, so Tang Ning, who had just come back, was dragged away again.

Bakewell enthusiastically introduces his masterpiece, the basic principle is that an image is engraved on a metal foil with insulating ink, and then rolled on a roller, and a pendulum pin is used to scan the picture progressively during identification, and the contrast between the conductive metal foil and the insulated image produces a telegraph signal, which can be transmitted through a guò wired telegraph line, and of course, after adjustment, it can also be sent using the wireless telegraph invented by Downing. The reason why it stayed in the real room stage was that the number of telecommunications generated in this way was so large that it would exhaust the limited resources of the telegraph.

Finally, Bakewell religiously begged for guidance, because the typewriter and wireless transmitter were already industrialized and the ease of use was astounding, and Bakewell was confident in Downing's creativity and hoped to be inspired. Of course, if Downing is stingy, it's no problem.

Tang Ning pondered for a moment, and when he looked up, he saw Bakewell's 50-year-old standing like a schoolboy, not treating his 25-year-old youth as a junior at all, he admired it and smiled: "Your invention is great, the only problem to solve may be too much information, right?" ”

"Yes, yes, yes!" While enjoying the compliments of the great young inventor, Bakewell thought about it himself.

Tang Ning reminded him: "When you see my paper tape transfer method, do you think of anything?" ”

Bakewell: "Uh...... I'm very impressed with the messages you discarded and deleted while the tape is in transit, it's so creative, you mean...... Relay image signals with paper tape and discard a large number of useless signals? Hey? It seems possible...... I'll think again. ”

Tang Ning said happily: "You really have a talent for invention, and you can make such a big improvement." ”

Of course, he won't completely click through it, this is not to find a competitor for himself, he can't tolerate that the functions that his telegraph does not have have been invented by others. Before leaving, he also said hypocritically: "If you come up with a way, our British telegraph company buys it at a high price, what did you just say?" You don't work in London? If you have an idea, we can offer you a high-paying job opportunity, and there are only a few senior engineers like you in the world! ”

The result of his hypocritical statement was that Bakewell had subsequently joined the British Telegraph Company as a senior researcher, because he had probably thought of a way, and he could not get around the patent for paper tape, and how much he wanted to see telegraph companies all over the world have access to fax machines in his lifetime.

Americans are really involved, Matthew from New York? Brady demonstrated daguerreotype and won an award. The process of photography is complicated, and, using mercury vapor for development, Downing kindly told Brady: "Mercury is a very active metal, toxic to most living things, you should be careful to protect yourself." ”

Brady laughed, "Really? But photography is so fun, I want to take pictures of celebrities all over the world, and when I heard that the queen is coming, I wonder if I can take a picture of her. ”

Tang Ning: "Haha, I don't know about this. Why don't you get me one? ”

Brady: "It's a great honor to see you handsome, it's rare in the world!" ”

He also thought that Tang Ning was the son of a noble family, until after the shooting, Tang Ning said: "I'm busy, please have time to send the photo to my house, this is my business card." The title written on it was "President of the British Telegraph Company", and the two major inventions of this cutting-edge company were quite famous at the fair, and occupied a large place in the exhibition area of the East India Company. Rothschild mix, can the pomp be small?

This is an era of masters, Samuel Lee, the founder of the American Colt Manufacturing Company? Colt came to England to expand his arsenal, this ...... It is an American inventor again, and the International Industrial Exposition is known as the heyday of the British Empire, but Downing witnessed American inventors one after another, dazzling, which is a symbol of the strong rise of the United States, making him wonder if he wants to change his life and go to the United States to develop...... Unfortunately, the British Telegraph Company has been created, and his bond with the British Empire is deepening, and I am afraid that he will not be able to go all the way casually.

Colt brought with him three types of firearms, all of which were revolvers he invented, which had a range of about 100 meters and was valued for firing continuously, while rifles of the same era had a long range but could not fire continuously. In 1845, the Texas Mounted Police, armed with a Colt revolver, were impressed by the repeating weapon after fighting the Indians armed with single-shot rifles. In 1846, Colt worked with U.S. Army Captain Walker to design the eponymous six-shot Walker revolver. Subsequently, the U.S. government placed an order for 1,000 of these pistols with Colt for the Mexican-American War. Colt's business is booming, no, it's time to expand his business in England.

Colt actually wanted to try to develop an underwater telegraph cable, but he abandoned the idea when he saw the wireless telegraph and claimed that it could cross the Atlantic, and the field was already monopolized by the newly established British telegraph company. Colt was on the side when Downing's apprentice introduced their boss, so he knew Downing and seeing that the other party was interested in the revolver, he enthusiastically introduced the benefits and performance of the gun himself.

Arms are the weapon of the state, and of course Downing is interested in this kind of thing, and the famous Samuel? Colt, thunderous, alas, he didn't like revolvers very much. I remember that there was a movie in which a master pinched the opponent's wheel and subdued the opponent, which made him feel that this kind of wheel gun was very unreliable. What's more, the magazine of the Browning pistol is hidden in the handle, which can increase the capacity and effectively use the space, and the reload will be the standard of modern pistols. Anyway, it's better to get a few self-defense than to often use the black weapon particle beam gun that you brought from the future. （http：／／)。 It is said that Bessemer, who invented the first large-scale steelmaking method, thought of finding a steelmaking method because he invented a new barrel but steel could not keep up.

In short, he bought three Colt Navy, because this one is relatively lightweight, only 1. 2 kg. For comparison, the Colt Walker 2 kg, the Colt Dragoon 1. 9 kg.

Downing also exchanged business cards with Colt and said, "I am experimenting with a steel-making method that will sell good steel at the price of iron, and I will contact you at that time." ”

Colt was surprised: "Really? That's amazing, it's amazing, invented wireless telegraphy, typewriters, and steel! ”

Away from his future big client, Downing continued his shopping and found something interesting: the Storm Prophet. It's the idea of putting 12 leeches in a box, and when a storm comes, the leeches will desperately climb high and then ring the bell. It's a cute invention.

In addition to industrial products, there are other treasures, perhaps more striking than novelty ones, such as the Koh-i-Noor, the world's largest diamond, which the East India Company stole from the Mughal dynasty in Delhi, India, to give to the Queen. In 1306, when the diamond first appeared in record, it was written in Hindi: "Whoever owns this diamond will have the whole world, but he will also know all the misfortunes of this world." It is only when God, or when a woman wears it, that it can be spared. ”

As you might expect, many maidens and ladies are interested in Koh-i-Noor.
