Although the lawsuit between the Ministry of Industry and the internal government supervision was settled, the uproar caused by the patent slowly fermented.

There are only three weaving mansions in the inner official supervision, which are in the capital, Suzhou and Hangzhou. However, the weaving industry of the entire Ming Dynasty, especially the textile of coarse cloth, is the largest in the Ming Dynasty, and there are all regions in the territory.

The weaving house belongs to the boutique organization, but the scale is limited, and the private weaving industry is the real head.

When I saw that the internal officials and supervisors also had to honestly buy technology from the Ministry of Industry to improve the loom. The guilds in the capital also understood that the imperial court was really serious about this patent.

Since there are rules, you need to use the rules, and in recent times, Liu Jie, a member of the Yu Hengqing Officials Division of the Ministry of Industry, has changed from a marginal figure who no one cares about to the number one celebrity in the capital.

The major guilds cleaned up a lot of their own unique skills, and then selected some less important ones to apply for patents in the Yu Heng Qing Division.

Patents are only valid for 10 years, and after 10 years, they will become a technology that anyone can use. Therefore, if others can prevent it, of course, they must apply for a patent, but if they can't prevent it, they must not let others know the formula.

Of course, some patents still have some value, and some patents are simply indiscriminate, and they want to be confused.

However, no matter what kind of technology, the directors of Yu Hengqing's department registered them one by one and issued patent licenses.

At this time, many people discovered that patents are not only limited in time, but also in terms of region, and there is also a transition period.

Not all technologies can be patented, such as some technologies that are now universal, and those businessmen who want to monopolize through patented technologies find that they can't be opportunistic at all.

Moreover, during the transition period, there are still people who come up with the same technology to apply for patents, and the Ministry of Industry will also screen the differences between the two technologies, and award a formal certificate to those who are excellent.

Although there are only three aspects of the patent statute, there are hundreds of detailed clauses that almost block the attempts of those who want to speculate.

However, the most lively thing now is the promotion of new textile machines. Because the Ministry of Industry in addition to the weaving government, but also in each state capital are ready to grant a patent beneficiary, willing to replace the new loom merchants, can apply to the Ministry of Industry, and then through the bidding, the Ministry of Industry will choose to cooperate with the business.

Cooperating with the Ministry of Industry is equivalent to getting a gold medal for avoiding death, and those merchants who are wealthy but have no official relations are a positive group of people.

After getting the news, they rushed to Beijing from all over the country to get this opportunity.

Although the weather in Jingshi has been hot recently, the enthusiasm of these merchants is even higher.

On this day, Zhu Zhanji went to Jiajiang Industrial Zone again, wanting to solve the problem of high-pressure punch on the spot.

Because in Europe, in the fifteenth century, hydraulic punches appeared, which could produce plate armor. Therefore, Zhu Zhanji naively thought at the beginning that this technology was not a problem for the current Daming.

But he is still too naïve, because today's Da Ming has no technical reserves in this area at all, that is, there is no one who understands this area. It's easy to go from one to two, from two to three, but from zero to one, it's much more difficult.

Although the technology of hydraulic forging is the same as that of Chungmi, it only needs a small amount of water to do it, not to mention the Yangtze River, even a small river can do it.

But if you want to use water power to drive a heavy forging hammer to stamp out silver coins, or plate armor, for the current Ming Dynasty, you have to start from scratch.

The main role of hydraulic power is to be stable, not violent, how to turn smooth hydraulic power into violent impact.

From the power output of the transmission part to the driving hammer during stamping. In the era when there were no chains, the problem that needed to be solved in the middle of the process of achieving the strength of stamped silver coins was far from one or two points.

In addition, cold forging and hot forging, the development of molds, the invention of sawtooth peripherals, and even the determination of silver coin patterns all require Zhu Zhanji and Zhu Di to take the idea personally.

This silver coin Zhu Zhanji wanted to adopt the design mode of Yuan Datou in later generations, because this kind of floating figure forging can be done now, but it is difficult to prevent it.

As for steel molds, today's craftsmen have mastered the wax etching method, and by hand polishing, they can get very fine molds, but they can't be mass-produced.

However, at this time, it is necessary to mention the material process. Because ordinary steel, under vigorous stamping, begins to deform after hundreds of times. Therefore, if you want to make a mold durable, you also need to study harder steel molds.

After the New Year, the Ministry of Industry sent a long-standing survey team to Nam An Province in search of a hard ore found there. However, although the ore is found, it cannot be refined, because the current mine furnace cannot burn the ore at all.

Even the craftsmen could not melt these ores with nitric acid, and there was nothing they could do.

Zhu Zhanji was also dumbfounded when he got the news, and only then did he remember that the melting point of tungsten is almost the highest among all metals, so it was used as a wick, and now there is no means to deal with this thing.

At this time, he remembered manganese steel again.

The use of manganese can be traced back to the Stone Age, when pyrolite was used as a pigment on cave paintings.

This thing is very common, and even the iron ore is very high in it. Moreover, like the Ma family's glazed kiln, manganese is needed to remove or add color to the molten glazed solution.

The temper of manganese and steel is very strange and interesting, and if you add three percent manganese to the steel, the resulting low-manganese steel is so brittle that it shatters when you knock it out.

Therefore, the earliest iron ore exhausted all methods in order to remove manganese from molten iron.

However, if more than 13% manganese is added to make a high-manganese steel, it becomes both hard and tough.

The hammers and horn anvils used by blacksmiths today are basically high-manganese steel, but people in this era do not know manganese, so they do not know what this mineral is.

When tungsten steel cannot be used temporarily, manganese steel can only be used to make forging hammers and dies.

When passing through Qingliangmen, this is one of the places where the entire Yingtianfu has changed the most in the past few months.

The establishment of the Jiajiang Industrial Zone immediately turned an area of Jiajiang into the most lively area in Yingtianfu, where the grain shop processed wheat and rice, and the gold and silver shops where jade was processed.

Since the land there was monopolized by the imperial court and private purchases and transfers were not allowed, the merchants who relied on the Jiajiang Industrial Zone to survive basically gathered in the area of Stone Town to negotiate business.

Zhu Zhanji, who was riding on a horse, was still thinking about how to improve this water forging press, when he suddenly heard a delicate voice with an aggrieved tone shouting: "Your Highness, someone is bullying me......"

This voice was not a pure Ying Tianfu official dialect, but with a bit of Xichuan accent, and Zhu Zhanji immediately heard that it was Lan Yan.

He turned his head to look and saw that on the second floor of a restaurant next to him, Lan Yan was standing at the window with his hand open the light veil of the mat hat, his little face full of grievances.

Before Zhu Zhanji could speak, the guards of Qingjie had quickly sent a team of people to surround the entire restaurant.

And at the beginning, the Jinyi guard, who was responsible for guarding the main road, also had two people go to the restaurant, and as soon as they heard that this woman knew the grandson, they immediately shouted: "No one is allowed to move, wait for His Highness's whereabouts!" ”

The noise in the restaurant immediately dissipated, and everyone's eyes were fixed on a young man in his early twenties. And the young man, who had a smug smile at the beginning, was dumbfounded at this time and trembled with fright.

Zhu Zhanji laughed, raised his hand and said: "Naughty, you will get married in a few months, and you dare to run around, be careful of the palace maid aunt beating you." ”

Seeing that Zhu Zhanji had opened her words, she became more and more aggrieved, and said, "Someone bullied me." ”

Zhu Zhanji's face was blank and he said, "Be cautious." What bullies don't bully, come down, I'll take you to a fun place. ”

In this era, a woman's reputation is extremely important, and this stupid girl was bullied with her mouth open and closed, but fortunately it was in plain sight, if it weren't for the public, just rumors could ruin her.

Li Liang quickly ran upstairs and said respectfully to Lan Yan: "Lan ...... Girl, the grandson will make the decision for you, this is not the place for you to stay, leave with the little one first. ”

Blue Smoke sighed, looked around, and realized that something was wrong. Although she has little social experience, she is not really stupid after all. She is a grandson Liangdi, and now she appears in the restaurant with maids and guards, and spreads it out, so that others can see her as a Liangdi!

At this time, she regretted it again, just because she was harassed by the other party, she was angry for a while, and she opened her mouth to call her grandson.

But the matter has come to this, and she can only hurriedly ask the girl Wutong to pack up her things and turn away.

At this time, the young man reacted and immediately knelt down and shouted. "My lord, the people are wronged, I haven't bullied ...... This girl. ”

In the face of outsiders, Li Liangke didn't have a good face, and while waiting for Lan Yan to go downstairs, he turned around and sneered: "You can tell a few Jinyi guards about this, Yang Qianhu, this matter is left to you." ”

Lan Yan was a little aggrieved, and went downstairs in a little panic, and came to Zhu Zhanji's horse in fear.

For this somewhat confused chick, Zhu Zhanji knows that he can't be scared, he will be stupid if he is scared, and he can't be connived, and if he is connived, he won't know that the sky is high and the earth is thick.

For her, the first thing is to let her know the rules, what can be done and what can't be done, and then she will be sensible.

Therefore, he deliberately said with a straight face: "I really don't understand the rules, can you come to this kind of occasion?" ”

Lan Yan didn't dare to speak, but dared to look at him with the eyes of a kitten begging for mercy, looking like he was begging for forgiveness and comfort.

The people around her were densely packed, and Zhu Zhanji no longer reprimanded her, leaned over and grabbed her arm. Before she could react, he put his arm around her and, with a cry of surprise, took her on the horse.

"Let's go!"
