An unprecedented patent meeting that lasted until late at night.

When the meeting ended, everyone sent their most sincere thanks to the Zhang family.

The proposal of the patent promoted the exchange of technology and promoted the progress within the Xuantie Guild.

However, Zhang Hao's abandonment of patents has laid a broad space for the nascent patent system.

For most of the next half a day, everyone came to the stage to do technical exchanges, and then among the many technical exchanges, everyone elected the sixth high-level of the Xuantie Guild:

The head of the patent department of the Xuantie Guild, Feng Tai from the Feng family.

On the day of its establishment, more than 200 patents were registered, and the first patent law was enacted. Of course, the current scope of patent enforcement is limited to the Xuantie Guild.

Surrounded by everyone, Zhang Hao and Zhang Shengde got into the carriage and returned to Zhang's mansion.

Along the way, Zhang Hao looked at the list of patents in his hand and smiled faintly.

At present, there are many patents in this patent, which are shared by more than two families.

There are also many patented technologies, which are in conflict with each other.

Of course, there are also some patented technologies that have just been registered, and they are not a few.

All this shows that within the Xuantie Guild, a technical competition has begun.

Good patented technology is priced as high as 100 Darkiron Coins, while poor technology is priced at only 0.5 Darkiron Coins.

Everyone first swore confidentiality, and then claimed the patented technology, and waited for the second month after the sale of Xuantie, at the beginning of each month, to pay the patent fee.

For the patent fee, the Xuantie Guild takes one-tenth as a handling fee, etc., and the remaining ninety percent is returned to the family to which the patent belongs or the person to whom the patent belongs.

"Wait for another ten or twenty days, and after everyone has integrated the new technology, the Xuantie market in Ninghe County will be more interesting! The progress of technology will surely lead to the transformation of the Xuantie market again!" Zhang Hao muttered to himself.

Zhang Shengde smiled and didn't say anything.

............

Early the next morning, when Liu Xian and the others stepped into the gate of the Xuantie Guild, they were surprised to find:

All stores have 'clearance' signs, and the larger the purchase, the more discounts.

What's going on?

Liu first found a few acquaintances to ask, but everyone smiled and didn't speak.

But seeing the bright smiles on everyone's faces, Liu Xian had more questions.

It wasn't until the afternoon that the word "patent" spread.

Technology cannot be disclosed, but the matter of 'patents' can. Even the guild carved the world's first patent law on the wall, and there was an endless stream of people who came to read it.

............

When the storm was surging in the Xuantie Guild, Zhang Hao had already returned to the family's smelting base, and a new change had also begun within the Zhang family.

At this time, what was shown in front of Zhang Shengde was already a complete 'steam turbine'.

It's really a steam turbine, which uses geothermal heat to heat water vapor to drive it.

Zhang Hao also looked at the steam turbine in front of him, with some excitement in his eyes.

In Zhang Hao's eyes, this machine is still rudimentary, but it is undeniable that it already has the charm of technology.

Because of technical limitations, there are two major technical difficulties in steam turbines that have not been solved.

One is the bearing problem. On the bearing issue, there is no ball bearing for the time being, so we can only use the refining method to temporarily refine a few pairs of particularly hard slip rings, which can be regarded as a temporary application.

The second is that the feed-water and steam system of the steam turbine in front of you is open-circuit, not closed-circuit. In this way, the steam pressure, efficiency, etc. will be low.

The water and steam system is also rudimentary. A water tank placed at a height of more than ten meters is lifted by several array French pumping machines.

Then, under the action of gravity, the water follows the pipes and enters the 'heaters' above the earthfire, which are a dozen curved, juxtaposed pipes, where the water becomes high-pressure steam.

As Zhang Hao personally opened the valve of the steam channel, the crazy water vapor rushed through the turbine blades, bringing a hissing sound, because the steam pipeline was designed to be open, and the noise was extraordinarily loud.

The steam frantically rushed through the steam turbine, and finally extended along the crude pipe to the outside of the Zhang family's enchantment, and was directly discharged.

The turbine began to spin slowly, and gradually, a roar was heard.

There is a roar because the rotor is unbalanced.

There is no way, at the moment, this machine is all handmade, and it is commendable to be able to barely turn it. That's it, and almost all the refiners of the Zhang family were used.

Driven by the steam turbine, the heavy grinding disc begins to rotate and accelerate.

In order to increase the speed, a few craftsmen went up to help push it.

In about a minute, the grinding disc has begun to spin. Once, this was the heaviest work, especially because of the expansion of the Zhang family's production, and the craftsmen in charge of grinding discs were exhausted.

Now it has been replaced by machinery.

The craftsmen looked at the self-rotating grinding disc with joy and let out heartfelt cheers.

Zhang Shengde and Zhang Shengye also opened their mouths slightly, in disbelief.

Once, it took several craftsmen and even cows and horses to drive this huge grinding disc, but now, apart from the two low-grade spirit stones used by the water-pumping machine, no other power was used—the earth fire was selectively ignored by them.

The steam turbine drives a large metal wheel (connecting rod wheel) as large as the grinding disc, and a vertical shaft is erected vertically on the outer edge of the round wheel, and a connecting rod is connected to the shaft, and the connecting rod is then connected to the vertical shaft on the grinding disc.

As the turbine accelerates, so does the speed of the grinding disc.

"Pour the ore!" Huang Mingshan yelled.

Truckloads of ore were poured into the grinding discs, which barely slowed down, and the ore was crushed like fine sand.

This efficiency is almost dozens of times higher than in the past!

Even bigger cheers erupted.

The rapid rotation of the machine and the roaring sound are so beautiful.

Huang Mingshan and others were intoxicated, and Zhang Shengde and Zhang Shengye were also intoxicated. Zhang Hao was even more intoxicated.

After a while, Zhang Hao took a deep breath to calm himself down. "What's next?

Well, it's the bearings!

But to produce bearings, you need machine tools. ”

The R&D and production of bearings require the assistance of machine tools.

Don't look at the bearing is very ordinary, but it is the pearl technology in the early stage of the industry, and its processing technology and processing accuracy far exceed the general parts.

Because of the bearing, in order to ensure the reliability and efficiency of the machine! Moreover, the technology of processing bearings is not simple at all, and it requires considerable experience and technical accumulation.

While everyone was still intoxicated by the rapidly spinning machine, Zhang Hao was already thinking about his future plans.

The most critical step in industrialization was the birth of machine tools.

With machine tools, there will be 'machine production machines'.

Now that we have a mechanical prime mover, it's time to start researching machine tools.

Next to him, Zhang Shengye suddenly shouted: "Little mouse, this machine produces a few more!"

Zhang Hao immediately called Huang Mingshan: "Huang Mingshan, hand over the drawings to Bai Xiaodong and them, and let them build them according to the drawings." ”

"Okay!" Huang Mingshan dragged Bai Xiaodong and turned around and ran back to the classroom - okay, it should be called a research room in the future.
