Chapter 20 Fluorescent Light

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

After years of melee, the warlords' heads had little money in their pockets.

But having no money means that the military power in your hands is unstable, and it is easy to cause mutiny and lead to the collapse of the regime.

In order to avoid this possibility, every warlord will rack his brains to plunder the wealth of the people after he takes office. The so-called geese pass by and pull out the hair, and the beast leaves the skin, causing the people to live in poverty.

So much so that Zhang Zuolin, who was entrenched in the Northeast in later generations, became a clear stream among many warlords in a sense. In his later years, Zhang Shaoshang sighed: "Why did the people in Northeast China support my old Zhang family so much at the beginning? It was because we did not collect their land."

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

In order to make money by any means, Feng Guozhang, who is now guarding Jinling, called the Beiyang government on the 16th of this month, demanding that it use treasury funds to urge him to use treasury funds to purchase opium from the Shanghai-City Foreign Medicine Office and ship it to Jiangsu and Guangdong provinces for sale to harm local compatriots. It is so ridiculous.

Nuo naturally knew about these things, but his ability was limited and he couldn't even control them.

Now that the stalls have been sold out, there will only be more and more places that require money. Just relying on the salary paid by the school will not do anything big.

The manuscript sent was probably just here in the United States, and it was still a long way from being reviewed and published in the newspapers. He could take advantage of this time to make a patent and sell it to the United States to make some money.

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

This small light bulb directly helped General Electric to dominate the electrical field for a century.

Then, while the incandescent lamp was improved, Beckler used discharge tubes and fluorescent substances to create fluorescent lamps as early as 1859. Although the efficiency of fluorescent lamps was very low and could not be practical at that time, many people still noticed that it had good development prospects.

General Motors noticed it very early and pointed out that fluorescent lamps will inevitably replace incandescent lamps in the future, so they spent a lot of effort to develop and develop them from the beginning, and spent decades of research. It was not until 1927 that they were successful.

With this patent, any factory in the world who wants to produce fluorescent lamps can charge a patent fee, and you can make a fortune by lying down.

Until later generations, even though LED lights had risen unstoppable, fluorescent lights still firmly occupy half of the market.

So once Cheng Nuo takes out this patent, whether it is sold to General Electric or its competitors, or starts a company by himself, he can get a lot of money.

He did it right away. Cheng Nuo returned to the house to find white paper and pencils, 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: electrode, mercury, argon, and phosphor.

Both ends are discharge electrodes, providing electron emission sources for electrons. Mercury and an inert gas argon are enclosed in the tube. Mercury is the main discharge gas, while argon plays a protective role.

At the same time, the inner wall is coated with phosphor powder. According to the Stokes principle, the ultraviolet rays emitted from discharge are converted into visible light, thereby achieving the lighting effect.

Cheng Nuo still remembers that when he was in school in his previous life, the classroom was filled with fluorescent lights. At that time, they called lamp sticks, and it was easy to flash suddenly when it was on. The whole classroom was like a dance hall, and the students also took advantage of this time to make a little noise.

Then I slammed the replaced lamp stick and a smoke would come out from it. I thought it was quite fun at the time, but now it is quite interesting to think about it.

After drawing the structure diagram, Cheng Nuo began to fill the contents one by one according to the structure according to the memory of his previous life.

When the last word fell, Cheng Nuo held the sketch in his hand and felt excited, as if he was touching a real fluorescent lamp.

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

According to the patent law amended in 1903 in the United States, physical models are no longer a necessary part of patent applications unless required by the Patent Office, except for perpetual motion machines.

In other words, Cheng Nuo now meets the conditions for patent application with this piece of paper alone, and does not need to prepare a physical fluorescent lamp.

Therefore, Cheng Nuo is very confident in this patent, and even adjusted the fluorescent substances to silicates and tungstates specifically to adapt to the technology of this era.

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

Keep this chicken that can lay golden eggs and don’t do anything in one go.

If the Americans cheated, they would have more advanced technology to counter him.

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

However, this time he did not mail it directly to the US Patent Office, but instead handed it over to his classmate, and joined him as Jiang Jiangzuo, an international student in the third batch of Boxer Indemnity.

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

But he chose to go back to China directly after graduation, but Jiang Jiangzuo chose to continue studying and prepare to graduate from a doctorate and then come back to serve his motherland.

Jiang Jiangzuo is also a very powerful figure. After graduating from the University of California, he continued to study at Harvard. He obtained his master's degree and doctoral degree in four years. Later, he returned to China to become the founder of the Department of Mathematics at Nankai University in Tianjin. After the victory of the Anti-Japanese War, he became the first director of the Institute of Mathematics, which played an indelible role in the development of domestic mathematics.

This time, he handed over the patent sketch to him, and out of trust in him, I hope that he can give full play to his local advantages and ensure the smooth application of the patent.

In his letter to him, Cheng Nuo elaborated on the key points of the patent in detail, hoping that he could play the greatest value of the patent and handed over the full power to him for disposal.

In addition, the letter also describes in detail the changes after he returns, hoping that Jiang Jiangzuo will return to China as soon as possible and fight side by side.

Finally, I didn't forget to go to Zhejiang Restaurant to buy some Zhejiang Province's specialties and sent them there.

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

Wenhui pulled the corner of his clothes and whispered: "Sir, are we sending the things to your friends?"

Cheng Nuo looked at the mail car driving towards the distance, and while breathing a sigh of relief, he said in a firm tone:

"Yes, not only friends, but also comrades-in-arms who are struggling in foreign countries!"
