Chapter 54 The Flying Machine

An unprecedented patent meeting lasted until late at night.

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

The patent proposal has promoted the exchange of technology and promoted the progress within the Black Iron Guild.

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

For the next half a day, everyone came to the stage to do technical exchanges; and then among the many technical exchanges, everyone selected the sixth high-level executive of the Black Iron Guild:

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

On the day the Patent Department was established, more than 200 patents were registered, and the first patent law was also enacted. Of course, the current scope of patent implementation is limited to the Black Iron Guild.

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

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

Among the current patents, many patents are shared by more than two families.

There are also many patented technologies that conflict with each other.

Of course, there are also some patented technologies that have fallen behind just after registration, and there are not a few of them.

All this shows that within the Black Iron Guild, a technological competition has begun.

The price of a good patented technology is as high as 100 black iron coins; while the price of a poor technology is even only 0.5 black iron coins.

Everyone swore to keep it secret first, and then claimed the patented technology, and waited for the second month after the black iron was sold, at the beginning of each month, to pay the patent fee once.

As for the patent fee, the Xuantie Guild will take one-tenth of it as a handling fee, etc.; the remaining 90% will be returned to the family or owner of the patent.

"Wait another ten or twenty days, after everyone has integrated new technologies, the black iron market in Ninghe County will be even more interesting! The advancement of technology will definitely trigger changes in the black iron market again!" Zhang Hao muttered to himself.

Zhang Shengde smiled and said nothing.

…………

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

All the stores have a sign of "clearance"; and the greater the purchase volume, the greater the discount.

What happened?

Liu Xian 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 'patent' thing spread.

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

…………

When the turmoil in the Xuantie Guild was raging, Zhang Hao had already returned to the family's smelting base, and a brand new revolution had also begun within the Zhang family.

What was displayed in front of Zhang Shengde at this time was already a complete 'steam turbine'.

It is really a steam turbine, which uses geothermal heat to heat water vapor to drive a steam turbine.

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

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

Due to technical limitations, there are currently two major technical difficulties in steam turbines that have not been resolved.

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

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

Its water supply and steam system is also very simple. A water tank placed at a height of more than ten meters is used to lift water through several array pumps.

Then, under the action of gravity, the water follows the pipeline and enters the 'heater' above the ground fire. This is a dozen curved and juxtaposed pipes, where the water turns into high-pressure steam.

As Zhang Hao personally opened the valve of the steam channel, the crazy steam rushed through the turbine blades, bringing a hissing sound; because the steam pipeline was designed as an open circuit, the noise was extraordinarily loud.

The steam rushed through the steam turbine crazily, and finally extended along the rough pipes to the outside of Zhang's barrier, and was discharged directly.

The steam turbine began to rotate slowly; gradually, there was a roar.

There is a roar, because the rotor is unbalanced.

There is no way, the current machine is all handcrafted, and it is very rare to be able to turn it barely. For this, almost all the refining masters of the Zhang family were used.

Driven by the steam turbine, the heavy millstone began to rotate and accelerate.

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

After about a minute, the millstone had started to spin. In the past, this was the heaviest job, especially because of the expansion of the Zhang family's production, the craftsmen in charge of grinding the discs were exhausted.

Now it has been replaced by machinery.

The craftsmen looked at the automatically rotating grinding disc with joy and cheered heartily.

Zhang Shengde and Zhang Shengye also opened their mouths slightly, unbelievable.

In the past, several craftsmen and even oxen and horses were needed to drive this huge millstone; now, except for two low-level spirit stones used for the pumping machine, no other power is used—the ground fire been selectively ignored by them.

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

As the steam turbine continues to accelerate, the speed of the grinding disc is also increasing.

"Dump the ore!" Huang Mingshan roared.

Carloads of ore were poured into the millstone; the millstone hardly slowed down, and the ore was quickly crushed like fine sand.

This efficiency is almost dozens of times that of the past!

Bigger cheers broke out.

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

Huang Mingshan and others were intoxicated by it, as were Zhang Shengde and Zhang Shengye. Zhang Hao was even more intoxicated.

After a while, Zhang Hao took a deep breath to calm himself down. "What should we do next?

Well, it's the bearings!

But to produce bearings, machine tools are needed. "

The research and development and production of bearings require the assistance of machine tools.

Although the bearing is very ordinary, it is the pearl technology in the early stage of the industry. Its processing technology and processing accuracy far exceed that of ordinary parts.

Because of the bearing, the reliability and efficiency of the machine can be guaranteed! Moreover, the technology of processing bearings is not simple at all, and requires considerable experience and technical accumulation.

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

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

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

Now that the mechanical prime mover is in place, it's time to move on to machine tool research.

Next to it, Zhang Shengye suddenly shouted: "Little mouse, how many more will this machine produce!"

Zhang Hao immediately called Huang Mingshan: "Huang Mingshan, give the blueprint to Bai Xiaodong and the others, and let them build it according to the drawing."

"Okay!" Huang Mingshan dragged Bai Xiaodong, turned around and ran back to the classroom—well, it should be called the research room from now on.
