At the beginning of the new year, people who had finished their New Year's holidays "go to work". Officials returned to the official office, workers returned to the workshop, and Yuwen Il returned to the laboratory and started the work of the new year with his colleagues.

The technical principles of gas internal combustion engines and the technical difficulties encountered during the development process have been published in journals. This new power technology has attracted the attention of the academic community.

Although feedback from all walks of life still takes time, Yuwen I feels that he and his colleagues are no longer "lonely", and more and more people will contribute different strengths to the development of internal combustion engines.

The plan for the year is spring. This year's experimental plan must be formulated, and all preparations must be made and personnel must be arranged to implement it. Therefore, Yuwen is very busy, but no matter how busy he is, he has to take the time to read the patent notice of the Patent Office and the first issue of the New Year of each journal.

Soon, a patent information came into his eyes: a new refrigeration technology with good practical prospects, using an air compressor, a series of simple equipment and refrigerant to form a pipeline circulation, can effectively achieve effective refrigeration and maintain low temperatures in the equipment under the premise that the compressor continues to operate.

This news aroused Yu Wen I's interest. He knew that many people have been working hard over the years to develop an effective refrigeration device.

Refrigeration is cooling, and it is a significant cooling. Its technology is related to heat: if an object loses heat, it will cool down, but how to effectively absorb heat is a headache.

The heat is illusory and cannot be sucked away by a pump like air. Yuwen remembers that his father had done experiments for him before, using various methods to cool down:

As we all know, the most basic way to cool down is to fan the fan, but the scope of application is very narrow. Later, there was a very special method, which was to put saltpeter into a cup filled with water (preferably ground into powder). The cup would become cold after the saltpeter dissolved.

The process of dissolution of saltpeter is an endothermic process, which is completely opposite to the dissolution of quicklime that exothermic heat, so the cup will become cold.

Or, apply alcohol on your arms, and the alcohol will evaporate, making people feel that the arms are chilly. The principle is that when alcohol evaporates, it will absorb heat. When a person's arms lose heat, it will naturally become cold.

The principle of cooling seems simple, but it is difficult to achieve the effect of cooling, such as allowing water to freeze or causing the room temperature to drop significantly.

The "air conditioner" that has been widely used today is a practical cooling device, but its cooling effect only makes the indoor temperature three or four degrees lower than the outdoor temperature, let alone make the water freeze, so this "air conditioner" can only cool down and cannot cool down.

Not that no one has tried using a lot of nitrate to cool, but the effect is not ideal and the cost is not low: the dissolved nitrate requires burning fuel to boil it dry, dissolve it, and absorb heat. This cycle will cause a considerable cost.

Other refrigeration methods, such as using alcohol, are similar to using saltpeter to refrigerate: the effect is not ideal and the cost is high.

It is said that many people have been working tirelessly to study refrigeration technology for more than 30 years, but in the end they find that it is not as good as the traditional refrigeration method: take ice in winter, put it in an ice cellar, and take it out in summer.

Putting ice cubes in the Ice Cricket (the refrigerator of this era) can refrigerate without any cost. It is simple and practical. It is nothing more than expanding the ice cellar to store more ice cubes.

Or dig a well on the ground (the deeper the well, the better). In summer, put fruits, wine and other beverages in a bucket, then put them in the well, and take them up overnight. The fruits and drinks are cold, but there is no cost (except for drilling wells).

Or, put fresh fruits and fruits in the well. Because the temperature in the well is low, the fruits and fruits can be stored for a long time and will remain fresh and not rot after being taken out.

Therefore, Yuwen International knew that the research on refrigeration technology has been not going well. Although countless people still launched "attacks" on this problem and developed various fancy refrigeration technologies, they all returned in a desperate situation in the face of cost.

If it is just refrigeration, it can be done in traditional ice cellars, ice magazines or even deep wells. If it is freezing (freezing into ice), decent refrigeration technology has not yet appeared.

Now, someone has applied for new refrigeration technology, and it is said that the prospect of practicalization is good, which makes Yuwen International very excited, and then a series of questions pop up in his mind.

Is it actually used an air compressor? What is the principle? Is refrigeration related to air compression?

What is refrigerant? Is the production cost high? What is the loss during use?

To use a series of simple-structured equipment, how simple is the structure?

What is the production cost of the entire set of equipment? What is the operation cost?

Is it safe to run? How long is the fault-free running time?

Can it be used as an air conditioner to cool the room? If possible, is the refrigerant safe? If it is leaked, will it pose a hazard to the people in the room?

If this problem is not solved, I'm afraid no one will dare to use it?

No, even if it cannot be used to cool down the residence, it is good to use it as an ice mirror...

Or make the scale bigger and create an ice cellar directly, wouldn’t that be...

Is this thing OK? How much does it cost? If it is appropriate, opening a new ice cellar in Mingsha will probably bring you money...

Yuwen's ideas spread very quickly and finally took them back. He quickly saw who the patent applicant was and whether he was a scholar he knew.

After seeing the name and origin of the patent applicant, Yu Wen I was stunned: Who is the scum?

Last year, a murder occurred in Bozhou, and someone was poisoned to death. The murderer was an assistant teacher in Bozhou Zhouxue and was the cousin of the deceased.

Yuwen I recognized this teaching assistant. The other party was a well-known chemistry scholar, with good looks and good character, but he did the evil deeds of relatives and poisoning and killing people. Therefore, Yuwen I thought that this person was a gentle scum.

However, this scum actually developed a new refrigeration technology and successfully applied for a patent?

Yuwen Il looked carefully again and saw the date when the patentee applied for the patent and the date when the patent office approved the patent.

This person submitted a patent application before the incident. Not long after, he was arrested. A few days after he was arrested, the Patent Office approved the application.

However, this person's relatives were poisoned and killed. The evidence was conclusive, and the evidence was complete. After the Ministry of Justice, Dali Temple, and the Censorate, the death penalty was sentenced to death and was soon executed.

However, the Patent Office still determined that the patent was valid according to relevant provisions of the Patent Act, and the patent owner was still that person.

This means that even if this person is punished, the ownership of the patent will still belong to his family, and the family can still enjoy the future benefits.

Yuwen Yin sat down for a while and sighed: "Why do you want to do something wrong? Isn't it good to do research with peace of mind?"

From this incident, we can see that the court was determined to safeguard the patent system and protect the legitimate rights and interests of patentees and their families. The purpose was to inspire talented people to engage in scientific research, inventions and creations.

Taking him as an example, the technical patents applied for by his father (Yuwen Kai) during his lifetime were free and charged. Those patents that charge (use fees) brought a steady stream of income to Yuwen International.

He also applied for some practical patents himself, and was paid for by many manufacturers, and his income was also good.

Therefore, Yuwen Yin has a good deal, so he can devote himself to becoming a technical officer and research advanced technologies such as internal combustion engines.

While feeling moved, a colleague came in, took today's newspaper and said loudly: "Big news, big news!"

Others came over and asked, "What big news?"

The man waved the newspaper and said, "The envoy of Silla from Haidong came to the capital to complain, claiming that Goguryeo and Baekje were invading the border last year, destroying its city and captive of its people. He was in a turbulent momentum and would not stop until he destroyed the country, so he begged the emperor to uphold justice!"

When everyone heard this, they sighed: "Oh, why did Goguryeo and Baekje bully people again?"

Chang'an newspapers have previously reported that Goguryeo and Baekje in Haidong formed an alliance to attack Silla together, but under the mediation of the dynasty, the three parties had already stopped their troops.

Now, Goguryeo and Baekje have done this, is it because they don’t take the dynasty seriously?

Someone asked: "What does the court say? Did the news say it?"

"Yes, the news says that the court is about to send envoys to Goguryeo and Baekje to mediate. If the other king does not know the truth, then don't blame the dynasty for 'do not say that he is not prepared for what he said!'"

"Don't say that you are not prepared for your words", that is, "Don't regret it afterwards, don't say that you didn't say it in advance" means the same as the final warning. If the other party does not listen, the next step is war.

Everyone was talking about this big news, but Yuwen I didn't pay attention to it because it was not his business. He focused on the internal combustion engine. The dynasty's use of Goguryeo and Baekje has nothing to do with the internal combustion engine.

After a while, Yuwen Iian was about to call his subordinates for a meeting, but the guards came to report that someone came to visit him.

Yuwen I asked who came, but only knew that the other party came from "Sha Polang".

"Kill the wolf?" Yu Wenyin murmured to himself, his face condensed.

Sha Polang, literally means the abbreviation of the three evil stars "Qian Sha, Pojun, and Greedy Wolf". Yuwen Yin knew that an institution specializing in military technology research is also called "Sha Polang".

The existence of "Shapolang" is not a secret to the academic community, but outsiders have no idea about the research conducted by this institution. Because the institution has a high "secret level", few people who work in it have any direct contact with the outside world.
