Tong Yuanchao really likes Meng Jianye's decision, not because of how much benefit he can have, but because he thinks that it is not a bad thing to seek protection in such a rainy day.

After all, in recent years, China has suffered a lot from foreign investors because of patent issues.

The Ship Machinery Research Institute has encountered such a time, which is a shipyard in the capital for foreign investors to build a bulk carrier in the supporting refrigeration device, the Ship Machinery Research Institute as early as the end of the sixties has mastered the core technology, so the price is two-thirds lower than similar foreign products.

After the demonstration, foreign shipowners also expressed their approval.

When the Ship Machinery Research Institute completed the manufacture of refrigeration equipment and delivered it to the shipyard for installation, the foreign shipowner rushed to cancel the contract for the refrigeration equipment ordered by the Ship Machinery Research Institute, regardless of the huge amount of liquidated damages.

Both the shipyard and the Ship Machinery Research Institute were stunned at the time, so they naturally wanted to ask what the situation was, and the shipowner did not hide it.

It turned out that he had just finished booking a ship in China and returned to China, but not long after, a Japanese trading company filed a civil lawsuit against him in the place where he ordered the ship, claiming that the refrigeration equipment on his ship infringed the intellectual property rights of the Japanese trading company, because the refrigeration equipment in China contained a large number of Japanese patents.

The shipowner's unreasonable demands on the Japanese trading company were naturally based on reason, but the evidence produced by the shipowner could not overturn the heavy patent certificates, and seeing that he was about to lose the lawsuit, the shipowner had no choice but to compromise.

That is to abandon Chinese products and turn around to purchasing Japanese products with patents.

Of course, the Ship Machinery Research Institute is not convinced, their refrigeration equipment is all explored by themselves little by little, how can it infringe on other people's patents, it is ridiculous.

However, when the shipowner showed a copy of the patent certificate of the Japanese trading company to the Ship Machinery Research Institute, all the people in the institute were dumbfounded, and the Japanese technology was not only nothing new, but also nearly three years later than China.

To say that plagiarism is also Japan's copying of China, there is absolutely no possibility that China will copy Japan.

However, people preemptively registered patents and obtained worldwide intellectual property protection, and even if the Ship Machinery Research Institute was reasonable, it could not seek justice, so it could only pinch its nose and admit it with hatred.

The research institute and several senior researchers jointly wrote a letter to the central government, suggesting the establishment of their own patent protection system, and it is said that the relevant laws and regulations have entered the stage of review and revision, and it is estimated that they will be promulgated and implemented after the two sessions next year.

However, before that, the domestic intellectual property protection system was still a blank, and the corresponding legal protection could only be obtained through Hong Kong Island, but this is not something that ordinary people can do.

Tong Yuanchao can't wait to apply for a patent for the welding machine he designed the next moment, so as not to be strangled by foreign companies, but the next moment he has to calm down.

"I'll leave the patent to me!"

Just when Tong Yuanchao was a little depressed, Meng Jianye's words made him widen his eyes in surprise.

"Don't look at me like that, it's not as simple as you think, it may take a long time to complete, so don't be too anxious, let's see how this welding machine is, but don't take anything up, it turns out to be a useless Xibei goods, then it's a joke." ”

Looking at Tong Yuanchao's stunned expression, Meng Jianye hurriedly explained, but his words were solemn, but Tong Yuanchao was relieved, because this scholar felt that he understood the implicit meaning of Meng Jianye's words.

It is important to know that China's patent law will be promulgated after the two sessions next year, and as long as it is delayed a little, the welding equipment that has just been developed can be justifiably applied for a patent in China.

So Tong Yuanchao couldn't help but sigh in his heart, feeling that he was really a little funny, and even counted on Meng Jianye to help him go to Hong Kong Island to apply for a patent, although now Meng Jianye relies on the strong momentum of the Endeavor Factory to have a little young and heroic appearance.

But after all, he is just a young man who is not very old, and he still can't eat at home, so how can he have any strong overseas relations? If so, how could Meng Jianye stay in such a small shipyard and climb to the sky a long time ago.

So Tong Yuanchao shook his head secretly, and Meng Jianye's words were put behind him as a nonsense, and he began to concentrate on explaining the specific structure and use of the carbon dioxide semi-automatic arc welding machine.

Meng Jianye didn't notice the strangeness of Tong Yuanchao, and he didn't know what he was thinking, so Meng Jianye quickly put his spirit into the semi-automatic welding machine in front of him.

The whole set of equipment consists of welding power supply, wire feeding system, welding gun, air supply device, and control system.

The power supply adopts direct current, and the reverse connection method is mainly used to rectify, so as to ensure the large density of current and the cooling effect of carbon dioxide gas on the arc column.

Although the disadvantages of the push-pull wire feeding mechanism have been overcome, the friction of the wire in the hose has become very large, so that the length of the hose can not exceed three meters, otherwise the welding wire will not work normally because of the friction.

For this reason, Tong Yuanchao selected stainless steel and fired it into a coil spring tube, and reinforced it with multiple strands of thin spring steel wire on the outer layer, so that the hose can be bent softly, which can not only be elongated to maintain the stability of the wire feeding, but also reduce friction, so that the hose length reaches five meters.

The air supply device is composed of cylinders, preheaters, pressure reducing valves, high and low pressure dryers, flow meters and solenoid valves, etc., which fully cooperate to make the high-pressure carbon dioxide liquid in the cylinder process into carbon dioxide gas that meets the quality requirements, and make it evenly and smoothly sprayed out from the nozzle of the welding torch to effectively protect the welding process.

As for the welding torch and control device, there is nothing special, they are all made according to the original design, and there is not much innovation in technology.

All in all, the whole set of carbon dioxide semi-automatic arc welding machine looks inconspicuous, but the performance is not inferior to similar products in Japan and Germany, if you have to find some shortcomings, it is developed, because of the hasty assembly, resulting in an extremely rough appearance, but who is back, whether the ability is strong or not is really not on the face, so Meng Jianye really doesn't care, he wants equipment that can work, and not a mascot for up.

In this way, Meng Jianye exchanged some views on carbon dioxide semi-automatic arc welding machine with Tong Yuanchao, and left satisfied.

In the afternoon of the same day, Meng Jianye took leave and did not go to work, but went to the local county telegraph office, asked for an international call, looked at the time, dialed a number on a notebook, and after connecting, a woman's voice came from the other end of the phone:

"Hey...... Who are you?"

"Mom, I'm Xiaoye!"
