Everyone knows that the humiliation of our modern history began with the Opium War, but what few people know is that after the fall of the Qing Dynasty, the Beiyang government sold this thing in an official capacity.

After years of fighting, the warlord leaders did not have much money in their pockets.

But the lack of money means that the military power in the hands is unstable, and it is easy to mutiny, leading to the collapse of the regime.

In order to avoid this possibility, every warlord will rack his brains to search for the people's fat and ointment after taking power.

So that Zhang Zuolin, who was entrenched in the Northeast in later generations, became a clear stream among many warlords in a sense, and Zhang Shaoshuai sighed in his later years: "Why did the people of the Northeast support my old Zhang family so much at the beginning, it was because we didn't accept their land." ”

It's as simple as that, it's as ironic as that.

In order to make money by unscrupulous means, Feng Guozhang, who is now stationed in Jinling, sent a telegram to the Beiyang Government on 16 June, asking it to use the pharmaceutical industry as an excuse to urge it to use the state treasury funds to purchase opium from the Hucheng Foreign Pharmaceutical Office and transport it to Jiangsu and Guangdong provinces for sale, so as to harm the local compatriots.

Cheng Nuo naturally knows about these things, but his ability is really limited, and he can't manage it if he wants to.

Now that the stalls have been laid out, there will only be more and more places that need money, and just relying on the salary from the school will not do much trouble.

It is estimated that the manuscript sent has just arrived in the United States, and there is still some distance before the manuscript is approved and published in the newspapers, so he can take advantage of this time to get a patent and sell it to the United States to make a fortune.

If you want to ask who is the patent maniac in this era, it is General Electric's Edison, who has more than 2,000 patents in his lifetime, the most famous of which is the improved light bulb, known as the "world invention king".

This small light bulb directly contributed to GE's century-long dominance in the electrical field.

Then, at the same time as the incandescent lamp was improved, as early as 1859, Bekele made a fluorescent lamp using a discharge tube and a fluorescent substance, although the efficiency of the fluorescent lamp at that time was very low and could not be practical, but it was still noticed by many people that he had a good development prospect.

General Motors noticed it early on, and had the foresight to point out internally that fluorescent lamps would inevitably replace incandescent lamps in the future, so it spent a lot of effort to develop and develop it from the beginning, spending decades of research time until 1927.

With this patent, any factory in the world that wants to produce fluorescent lamps can collect a patent fee and make a lot of money lying down.

Until later generations, even if LED lights have risen unstoppably, fluorescent lamps still firmly occupy half of the market.

Therefore, once Cheng Nuo takes out this patent, whether it is sold to General Electric or its competitors, or he opens his own company for licensing, he can get a lot of money.

Cheng Nuo returned to the house and found a blank paper and pencil, and began to write and draw.

The structure of a fluorescent lamp is actually very simple, essentially a discharge tube, which is mainly divided into four parts: electrode, mercury, argon, and phosphor.

At both ends are discharge electrodes, which provide an electron emission source for electrons. The tube is sealed with mercury and argon, an inert gas, which is the main discharge gas and argon which plays a protective role.

At the same time, the inner wall is coated with phosphor, which converts the ultraviolet rays of discharged radiation into visible light according to the Stokes principle, so as to play a lighting effect.

Cheng Nuo still remembers that when he was in school in his previous life, the classrooms were full of fluorescent lights, and at that time they were called light sticks, which were easy to light up and suddenly flicker, and the whole classroom was like a dance hall, and the students also took advantage of this time to make a little noise.

Then I smash the replaced light stick, and there will be a puff of smoke coming out of it, which I thought was fun at the time, but now I think it's quite interesting.

After drawing the structural diagram, relying on the memory of his previous life, Cheng Nuo began to fill in the content one by one according to the structure.

When the last word fell, Cheng Nuo took the sketch in his hand, and his heart was full of excitement, as if he was touching a real fluorescent lamp instead of paper.

Although the domestic bulb factories are still very backward and have no industrial capacity to manufacture fluorescent lamps on straw paper, Cheng Nuo is still not afraid.

According to the U.S. Patent Act, as amended in 1903, a physical model is no longer a necessary part of a patent application unless required by the Patent Office, with the exception of perpetual motion machines, of course.

In other words, Cheng Nuo now only relies on this straw paper to meet the conditions of the patent application, and there is no need to prepare the fluorescent lamp.

Therefore, Cheng Nuo is very confident in this patent, and even adjusted the fluorescent substances to silicate and tungstate in order to adapt to the science and technology of this era.

If possible, it may be possible to prepare multiple patents and follow the technical ladder to harvest GE wool at regular intervals.

Keep this chicken that can only lay golden eggs, and don't do a hammer deal.

In case he is cheated by the Yankees, there is more advanced technology in his hands to counter him.

Without further ado, Cheng Nuo simply had lunch, folded the sketch in his hand, and threw it to the United States.

However, this time he did not mail it directly to the U.S. Patent Office, but handed it over to his classmates, Jiang Jiangzuo, who was with him as an international student in the third batch of Gengzi indemnity.

When they were studying in the United States, the two had a very good relationship and often discussed math problems together.

It's just that Cheng Nuo chose to return to China directly after graduating from his bachelor's degree, while Jiang Jiangzuo chose to continue his studies and prepare to return to serve the motherland after graduating with a doctorate.

Jiang Jiang Zuo. After graduating from the University of California, he continued his studies at Harvard, obtained a master's degree and a doctorate degree in four years, and later returned to China to become the founder of the Department of Mathematics of Nankai University in Tianjin, and became the first director of the Central Research Institute of Mathematics after the victory of the Anti-Japanese War, which played an indelible role in the development of mathematics in China.

I gave him the patent sketch this time, and I also knew the roots, and out of trust in him, I hoped that he could give full play to his local advantages and ensure the smooth application for the patent.

In his letter to him, Cheng Nuo elaborated on the key points of the patent, hoping that he could give full play to the maximum value of the patent and give him full authority to dispose of it.

In addition, the letter also described in detail the changes after his return, and hoped that Jiang Jiangzuo would return to China as soon as possible and fight side by side.

In the end, I didn't forget to go to the Zhejiang restaurant to buy some Zhejiang Province specialties and send them over.

There are not many things, and I hope to comfort my homesickness for a while.

Wen Hui tugged at the corner of his clothes and whispered, "Sir, are we sending things to your friends?" ”

Cheng Nuo looked at the mail truck heading into the distance, and while breathing a sigh of relief in his heart, he said in a firm tone:

"Yes, not only friends, but also comrades-in-arms struggling in a foreign land!"
