When Song Yingsheng arrived at the patent office, the first three committee members were holding the latest patent application summary table in view, and Yusheng here everyone has their own business, and the patent office transferred to the patent office except for the miscellaneous staff there is no permanent manpower, everyone is waiting to review the audit project at hand back to their original duties, come over in the morning to drink tea and chat, look at the newspaper The days of mixing for a day are impossible to happen in all levels of departments with Yusheng.

There is also a standard process for validation, and there will be no things that are too hasty and make the pearl dusty...... In fact, most of the patent examinations can be seen as a joke, and those who have been here a few times are fine, and the newly transferred ones will inevitably lose their temper.

"Hello everyone!" Song Yingsheng and these few are acquaintances, he glanced at the door, and then said hello.

Several members of the review committee looked happy, and Song Yingsheng shook his head: It is obviously still the performance of a newcomer.

"Brother Song is good." A young man from Datong Mansion pointed to the report in front of his case, and said with a smile: "This person said that he used the steam from his own teapot to test the steam engine, which can drive the carriage, in his words, the power is inexhaustible, and the carriage can drive to the ends of the earth." ”

"It's completely worthless, he can't even tell the difference between crank motion and circular motion." Another member sighed: "The concept of the steam engine was proposed by the adults themselves. It does make sense, we have been studying this 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, and what can be done now is to boil the steam pot, and the steam enters the ball installed on the horizontal shaft through the pipe, and then rushes out of the two crank pipes, pushing the pipe in opposite directions, and then, the ball turns ......"

The committee member who spoke spread his hands with a helpless expression, and the rest of the people had almost the same expression.

"According to your lordship." Song Yingsheng said with a smile: "This kind of design and achievement has been on Taixi's side for more than a thousand years. ”

"yes, it's frustrating."

"The Tessians are really unique in machines."

"If this steam engine is completed, it will be very useful in the mine, pumping water and transporting ore, which is much more effective than manpower."

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

The research institutes of the patent institute and various bureaus, in addition to the master craftsmen like Wang Debang, can enter it, that is, skilled craftsmen with ideas and practical skills, and then there are scholars who are very interested in miscellaneous studies, arithmetic and geometry are the foundation, in recent years, even ordinary craftsmen are strengthening their learning, but in a few years, the harvest is still limited after all.

And proficient in all kinds of miscellaneous studies, arithmetic and geometry, and also interested in machinery and metallurgical casting or have a little foundation in the reader, that is really rare, the Song family brothers, in He Yusheng is already a top talent.

A committee member patted his head and said in surprise: "Brother Song doesn't seem to be on duty 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, envy."

"Brother Song's talent must be a very noteworthy patent."

The heads of several committee members immediately came together.

"Title, New Brass Melting Casting Method."

"Subtitle: Zinc is a new metal, and brass is obtained by combining zinc and copper and smelting."

The three committee members raised their heads and looked at Song Yingsheng like elementary school students.

"What does Brother Song mean...... the youngest committee member said excitedly: "That means that calamine can be discarded, and this metal called zinc can be directly smelted with copper, and brass can be obtained?" ”

"Exactly." Song Yingsheng still didn't plan to take this credit on his head, he smiled and said: "This discovery is actually the credit of my brother, I just helped to sort out some information." ”

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

"Haha." Song Yingsheng smiled from ear to ear, and he said, "If you feel that there is no big problem with the report, I would like to ask the institute to conduct an actual test as soon as possible." ”

"Of course." Several committee members replied together: "We will definitely seize the time, this report can bring huge profits to the military department, how dare we delay." ”

"Yes." Song Yingsheng said angrily: "I heard that the budget of the military department next year is tight, how can we not make a difference." ”

The budget of the Finance Bureau will definitely not disclose the detailed figures, but it will also release some rumors, after all, all departments will compete for the budget, and the budget will be revealed every year, so as not to make the budget of the lion and fight endlessly. But many people don't know that next year's budget crunch is not a boring game of wolves, but a real reality, the top level of the military department is very nervous about this, and the middle level also vaguely knows some, although it is not detailed, but it is enough to show loyalty.

As for the price reported by Song Yingsheng, it must be more than a thousand taels as little as Wang Debang and others rewarded back then.

In terms of the purchasing power of silver, a thousand taels must be a heavy reward, but now everyone has understood that Zhang Han attaches great importance to the technical level, and also knows that various technical patents are equal to profits, and even some patents, such as research in pure disciplines such as arithmetic, as long as they can justify themselves and submit papers, the military department will not hesitate to reward them materially.

Zhang Han's idea is very simple, the reason why the eight-strand article makes the smartest group of people in the Chinese tireless, is not that its subtle words and righteousness are really attractive to such a degree, it should be said that a considerable number of readers study the eight-strand and figure out that the text is just for profit, what to read the sage book and do the sage thing, there may be a few people who really think so, most people just take it out as a stepping stone to wealth.

If Zhang Han can give a considerable number of scholars another path, they can also get rich and rich, and they don't need to fall into the current literature, and they can choose miscellaneous studies according to their own interests and hobbies to study, I am afraid that in time, it may be a few decades later, China can appear in the real sense of the academic powerhouse, that is, the universities that have been widely owned in the West in this era.

Many people may not know that there have been quite a lot of institutions of higher learning in Europe, and 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 the university, this era is also the era when European science and technology began to blow out, 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. And it is precisely these two disciplines that laid the foundation for the development of the West for hundreds of years.

Philosophy is the core of civilization, and mathematics is the foundation of all science!

It can be said that in order to transform the core of Chinese civilization, Zhang Han spared no money in this regard.

If a small amount of silver is used to create China's first multidisciplinary university, instead of the pure Confucian school of Bailu Academy, Zhang Han feels that even if he can't achieve hegemony in the end, this life will be worth it.

"I remember the highest grade of academic patent report, and the prize money was in the tens of thousands of taels." After Song Yingwu walked out, the youth committee member said in a very envious tone.

……

"Well, it's zinc."

Han Lao Liu happened to turn back to Li Zhuang on the Lingqiu mine, planning to rush back to the copper mine a year ago, most of the families of the middle people moved to the grassland, Han Lao Liu's family lived in the military fort outside the copper mine, this time he came back on business, he has returned to his heart like an arrow.

Now Datong no longer looks like home, but the grassland where the northern captives used to be entrenched, but like a place where home is.

After all, where the family is, is where the family is.

The military secretary proposed to ask Han Lao Liu to preside over the smelting, Han Lao Liu had no way to refuse, he had been in the copper mine, and the theory of these things may not be strong, but decades of experience as a miner were not covered, otherwise, the double-chamber iron-making method would not have been proposed by him, and the test was successful.

"It's copper."

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

Beneath both supplies is a raging fire.

Han Lao Liu smiled and said, "Okay, wait for time." ”

Sun Jingting nodded and said, "It's hard work." ”

Han Lao Liu said: "It's nothing, if this thing is done, when I go back to the mine, it can be regarded as a great news to bring back." ”

"That's true." Sun Jingting also couldn't hide a smile on his face, and he said to the two brothers of the Song family: "The two of you are really geniuses, this matter can be regarded as a miracle, if it succeeds, I will send Tang Ma Fei to report to the adults to know." ”

The two brothers of the Song family both bowed down, Song Yingsheng's face was a little uneasy, this matter was too noisy, and he was a little worried. Song Yingxing doesn't care, the matter in front of him is that he has read a lot of classics, visited a lot of copper mines and iron mines, and after many tests, if he is not sure, Song Yingxing will not take out this achievement.

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

In the Ming Dynasty, there was a technology to use calamine to refine brass, and in the literature of the Ming Dynasty, it is clearly recorded that the brass furnace such as the Xuande furnace was cast, as well as the record of casting brass copper coins.

Whether it is copper such as Xuande furnace or brass coinage, its value is of course far more than that of raw copper.

Brass decays very slowly, retains its luster for a long time, and has good stretchability, and casts or 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, and there is no one who does not like better metal objects.

But with calamine casting brass, the technology is complex, it takes a long time, the Ming Dynasty large-scale casting Xuande furnace is in the Xuande period, the quantity is large, the quality is good, one is that the Myanmar tribute copper was obtained at that time, the quantity is very large, the second is that the national strength is strong during the Xuande period, with a large number of qualified craftsmen, can mobilize a large number of manpower and material resources to cast copper.
