When Song Yingsheng arrived at the patent office, the three members were reading the latest patent application summary form. Everyone here had their own affairs. Except for the mailbox, there were no permanent staff. Everyone was waiting to complete the review of the review items at their hands and return to their original duties. They came here in the morning to drink tea and chat, and read newspapers and spend a day together. It was impossible for them to be born in Heyusheng's departments at all levels.

There are also standard procedures for the approval, and there will be no such thing as being too hasty and keeping the pearls covered in dust... In fact, most patent reviews can be regarded as jokes. It would be fine if you stay here a few times, but the newly transferred ones will inevitably lose their composure.

"Hello everyone!" Song Yingsheng and these people were all acquaintances. He walked in and glanced at the door, then bowed and said hello.

Several review committee members looked overjoyed, and Song Yingsheng shook his head: It was obviously a newcomer's performance.

"Hello Brother Song." A young scholar from Datong Prefecture pointed to the report before the case and said with a smile: "This person said that he used the steam burned from his teapot to test the steam engine, which can drive the carriage. In his words, it is powerless, and the carriage can drive to the ends of the world."

"It has no value at all. He can't even distinguish between crank movement and circular movement." Another committee member sighed: "The concept of steam engine was proposed by the adults himself. It makes sense. We have been studying this matter recently, but it feels too difficult. What we can do now is to improve the airtightness function. To be honest, the military department has spent thousands of taels of silver in this regard. What can be done now is to boil the steam pan, and the steam enters the ball installed in the horizontal axis through the pipe, then rush out from the two crank tubes, push the pipe in the opposite direction, and then the ball rotates..."

The speaker spread his hands with a helpless look on his face, and the rest of the people had almost the same expression.

"According to the adults," Song Yingsheng smiled and said, "This design and result has been in Taixi for more than a thousand years."

“Yes, it’s frustrating.”

“The Teesi really have unique features on the machine.”

"If this steam machine is done, it is very useful in the mines, pumping water and carrying ore, which are much more effective than manpower."

Speaking of this, everyone looked at each other, shook their heads and sighed.

In addition to the great craftsmen like Wang Debang who can enter the patent institute and various bureaus, they are skilled craftsmen with ideas and practical skills, and then scholars who are very knowledgeable and interested in miscellaneous studies. Mathematics and geometry are the foundations. In recent years, even ordinary craftsmen have been strengthening their studies. However, in a few years, the gains are still limited.

It is rare for scholars who are proficient in various miscellaneous studies, mathematics and geometry, and are interested in machinery and metallurgical casting or have a little foundation. Those of the Song brothers are already top talents in Heyusheng.

A member slapped his head and said in surprise: "Brother Song doesn't seem to be a rotation today?"

"I have a report to submit." Song Yingsheng smiled and handed over a report.

"It turns out that Brother Song actually has a patent, so I'm envious."

"Brother Song's talent must be a patent worth noting."

The heads of several committee members immediately got together.

"Title, new brass casting method."

"Subtitle: Zinc is a new metal, made of zinc and copper and melted and cast, and you can get brass."

The three members raised their heads and looked at Song Yingsheng like a primary school student.

"Brother Song means..." The youngest committee member said with an excited look: "That is to say, calamine can be discarded and smelted directly with this metal called zinc and copper to get brass?"

"It's totally correct." Song Yingsheng still didn't plan to count this credit on his head. He smiled and said, "This is actually my brother's credit. I just helped to sort out some information."

"Brother Ling is really a genius." The youth committee member praised, and then said embarrassedly: "Brother Song is also a great talent, which is really admirable!"

"Haha." Song Yingsheng laughed so hard that he couldn't stop talking, and he said, "If you feel that the report is not a big problem, I would like to ask the institute to conduct actual experiments as soon as possible."

"Of course." Several members replied together: "We will definitely seize the time. This report can bring huge profits to the military department, how dare you delay it."

"Yes." Song Yingsheng said with a sigh: "I heard that the Military Command will have a tight budget next year, so how can we not put in some effort?"

The budget plan of the Finance Bureau will definitely not reveal detailed figures, but it will also make some noise. After all, all departments will compete for budgets. If the budget is tight, it will be revealed every year, so as not to open the lion when making budgets. But many people don’t know that the budget tight next year is not a boring game where the wolf is coming, but a real reality. The senior management of the Military Affairs Office is very nervous about this, and the middle-level personnel also know something. Although it is not detailed, it is enough to express loyalty.

As for the price reported by Song Yingsheng, it is definitely not just as little as Wang Debang and others rewarded a thousand taels at that time.

In terms of the purchasing power of silver, a thousand taels are definitely a reward, but now everyone understands Zhang Han’s emphasis on the technical level, and also knows that various technical patents are equal to profit, and there are even some patents, such as pure disciplines such as mathematics. As long as you can make up for your own argument and submit a paper, the Military Office will not hesitate to material rewards.

Zhang Han’s idea is very simple. The reason why the eight-legged articles make the smartest group of Chinese people tirelessly is not that their subtle words are really attractive to such a point. It should be said that a considerable number of scholars study eight-legged articles and guess that the current articles are just for the benefit of reading sages and doing things about sages. Perhaps a few people really think so, and most of them just take them out as stepping stones to wealth.

If Zhang Han could give a lot of scholars another way, he would also be able to gain wealth and not be able to get out of the current literature. He could choose miscellaneous studies according to his own interests and hobbies to study it. I am afraid that in time, it may be that in a few decades, China will have a real academic focus, that is, universities that have been widely owned in the West in this era.

Many people may not know that there are already quite a lot of higher education institutions in Europe. In later generations, a well-known European university has a history of thousands and hundreds of years, and has cultivated quite a lot of talents in universities. This era is also an era when European science and technology began to explode. The shackles of theology were broken, and the wealth brought by the great voyage accumulated social wealth to a certain extent, which was enough to support the academic research of many scholars, and even the seemingly useless philosophical and mathematical research. It was precisely these two disciplines that laid the foundation for the success of the West for hundreds of years.

Philosophy is the core of civilization, while mathematics is the foundation of all sciences!

It can be said that in order to transform the core of China's civilization, Zhang Han is not hesitant to pay any attention to this.

If a small amount of silver is used to create China's first multidisciplinary university, instead of the pure Confucian school like Bailu Academy, Zhang Han felt that even if he could not achieve hegemony in the end, his life would be worth it.

"I remember the highest-level excellence academic patent report, the bonus is 10,000 taels." After Song Yingwu walked out, the youth committee member said in a very envious tone.

...

"Well, this is zinc."

Han Laoliu happened to return to Lizhuang at Lingqiu Mine, planning to rush back to the copper mine before the New Year. Most of the middle-aged family members moved to the grassland. Han Laoliu's family lived in a military fort outside the copper mine. This time he came back for business, and he was already home.

Now Datong no longer looks like a home, but the grassland that was occupied by the Northern Territory before, but instead looks like the place where the home is.

After all, the family is where the family is.

The military department asked Han Laoliu to take charge of the smelting matter, but Han Laoliu could not refuse. He has been in the copper mine and his theory of these things may not be very strong, but decades of miners' experience are not built. Otherwise, he would not have proposed the double-chamber iron smelting method and the experiment was successful.

“This is copper.”

In front of Sun Jingting and the Song brothers, Han Laoliu added zinc and copper in turn.

Below the two materials is a burning fire.

Han Laoliu smiled and said, "Okay, wait for time."

Sun Jingting nodded and said, "Thank you for your hard work, I'm already a sixth child."

Han Laoliu said: "It's nothing. If this matter is done, I will take it back with great news when I go back to the mine."

"It's true." Sun Jingting couldn't hide his smile on his face. He said to the two brothers of the Song family: "You are really geniuses. This matter is also considered a magical achievement. If it succeeds, I will send Tangma Fei to the Lord to know."

The two brothers of the Song family bowed, and Song Yingsheng's face was a little uneasy. The incident was too disturbing, so he was a little worried. Song Yingxing didn't care. He had read many classics and visited many copper and iron ore. After many tests, if he was not sure, Song Yingxing would not have taken out the result.

Before the Ming Dynasty, China cast copper, whether it was copperware or copper coins, from bronze to copper. The bronze was mixed with impurities such as nickel and aluminum, and copper was the original copper extracted from copper stone.

It was not until the Ming Dynasty that the technology of using calamine to extract brass was clearly recorded in the Ming Dynasty documents. Brass furnaces such as the casting Xuande furnace and also the casting of brass copper coins.

Whether it is copper such as Xuande Furnace or brass minting coins, its value is of course far greater than that of original copper.

The color of brass is slow to decay, can maintain its gloss for a long time, and has good stretchability. Casting objects or mint coins are more beautiful and durable than original copper.

This is the reason why brass was used on a large scale in the Ming Dynasty. No one doesn't like better metal objects.

However, the technology of using calamine to cast brass was complex and took a long time. The large-scale casting of Xuande furnace in the Ming Dynasty was in the Xuande period. It was in large quantities and good quality. One reason was that it obtained the highest-quality tribute copper from Myanmar at that time, and the other reason was that the national strength was strong during the Xuande period, with a large number of qualified craftsmen, and could mobilize a large amount of manpower and material resources to cast copper.
