Go back to the past and be a schoolboy

Chapter 20 Fluorescent Lamps

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 melee, the warlords had little money in their pockets.

But without money, it means that the military power in your hands is unstable, and mutiny is prone to occur, leading to the collapse of the regime.

In order to avoid this possibility, every warlord will rack his brains to search for people's fat and people's cream after he takes power.

As a result, Zhang Zuolin, who was entrenched in the Northeast in later generations, became a clear stream among the many warlords in a certain sense. In his later years, Shaoshuai Zhang expressed emotion: "Why did the people in the Northeast support my old Zhang family so much at the beginning? It is because we don't accept them. Land."

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

In order to get money by any means, Feng Guozhang, who is now sitting in Jinling, called the Beiyang government on the 16th of this month, asking for the excuse of pharmaceuticals, urging it to use the treasury funds to buy opium from the Shanghai Foreign Medicine Office, and transport it to Jiangsu and Guangdong provinces for sale, so as to eliminate the scourge. Local compatriots, how ridiculous.

Cheng Nuo naturally knew about these matters, but his ability was really limited, so he couldn't control them if he wanted to.

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

The manuscript that was sent was estimated to have just arrived in the United States at this point, and there was still some distance before the manuscript passed the review and was published in the newspapers. He could take advantage of this time to create 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, Edison of General Electric has more than 2000 patents in his life. Among them, the most famous invention is the improved light bulb, known as the "King of Invention in the World".

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

Then, while incandescent lamps were being improved, Becquerel used discharge tubes and fluorescent substances to create fluorescent lamps as early as 1859. Although the efficiency of fluorescent lamps was very low at that time and it was not practical, many people still noticed that he had a good reputation. Prospects.

General Motors noticed it very early, and pointed out internally that fluorescent lamps would replace incandescent lamps in the future. It is considered a successful development.

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

Until later generations, even though the rise of LED lamps has been unstoppable, fluorescent lamps still firmly occupy half of the market.

So once Cheng Nuo took out this patent, whether he sold it to General Electric or its competitors, or started his own company to license it, he could get a lot of money.

Going to do it, Cheng Nuo went back 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. It is essentially a discharge tube, which is mainly divided into four parts: electrodes, mercury, argon, and phosphors.

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

At the same time, the inner wall is coated with fluorescent powder, which converts the ultraviolet radiation radiated by the discharge into visible light according to the Stokes principle, thereby achieving the lighting effect.

Cheng Nuo still remembered that when he went to school in his previous life, the classrooms were full of fluorescent lights. At that time they were called light sticks, and they were easy to light up and suddenly flicker. The whole classroom was like a dance hall. The students also took advantage of this time to laugh A little hustle and bustle.

Then step on the replaced light stick, and there will be a burst of smoke from it. I thought it was quite fun at the time, and it is quite interesting in retrospect.

After drawing the structure 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 held the sketch in his hand, and his heart was full of joy, as if what he touched was not paper but a real fluorescent lamp.

Although the current domestic light 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 law amended in 1903, unless required by the patent office, physical models are no longer a necessary part of patent applications, except of course perpetual motion machines.

In other words, Cheng Nuo now meets the conditions for a patent application with just this scrap of paper, and there is no need to prepare the actual fluorescent lamp.

So Cheng Nuo was very confident in this patent, and even adjusted the fluorescent substances to silicate and tungstate specifically to adapt to the technology of this era.

If possible, it may be possible to prepare multiple patents, and follow the technical ladder to collect General Electric's wool every other time period.

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

In case of being tricked by the Yankees, there are more advanced technologies in hand to counter him.

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

But this time he didn't mail it directly to the US Patent Office, but handed it over to his classmate, Jiang Jiangzuo, an international student who joined him as the third batch of Gengzi indemnity.

When they were studying in the United States, the relationship between the two was very good, and they often discussed mathematics problems together.

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

Jiang Jiangzuo is also a very powerful person. After graduating from the University of California, he continued his studies at Harvard. He obtained a master's degree and a doctorate degree within four years. He returned to China and became the founder of the Department of Mathematics at Nankai University in Jinmen. He also became the first director of the Central Research Institute of Mathematics, and played an indelible role in the development of domestic mathematics.

Handing over the patent sketches to him this time is also a matter of knowing the basics. Out of trust in him, I hope he can give full play to his local advantages to ensure smooth patent application.

In his letter to him, Cheng Nuo explained the key points of the patent in detail, hoping that he can maximize the value of the patent and leave it to him to handle 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.

Finally, I didn’t forget to go to the Zhejiang restaurant to buy some special products of Zhejiang Province and send them over.

There are not many things, I hope it can temporarily comfort the homesickness.

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

Cheng Nuo looked at the mail van heading into the distance, and while heaving a sigh of relief, he said in a firm tone:

"Yes, not only friends, but also comrades in arms fighting in a foreign country!"
