Chapter 795: Compass

The craftsman shook the handle, and under the drive of the handle gear, the big drum on the top began to rotate, and with the rotation together, the gears on the small drum connected to the big drum also began to rotate, but after only five or six turns, the gears of the big drum and the small drum were stuck because of poor coordination.

"Look, Master Hou, it's only been a few turns and it's stuck!" The craftsman said angrily.

"Master Hou, if the small drum below is not driven by gears, the mud is too sticky and sticks to the drum, and the small drum will inevitably not be able to rotate flexibly, this blind man can see it!" The craftsman was also unconvinced, muttering beside him.

"What do you think?" Chen Xu turned his head and asked the group of craftsmen and craftsmen gathered next to him.

"I think what Carpenter Tan said makes sense, dirt is not an item such as wood and cloth, if it is too sticky, the small drum will not be able to rotate!" An old craftsman with gray hair next to him pulled his beard and said.

"Hmph, you see I'm not wrong, there's something wrong with your design!" Carpenter Tan snorted proudly.

"Yes, I think so!" A few others nodded in agreement.

The craftsman's face instantly became ugly, staring at the machine and constantly pulling his beard, and after a long time, he sighed and said: "Then if the gear is not solved well, this pottery plate machine will not work, it seems that it is a waste of effort!" ”

"How can it be in vain, your ideas and creativity are very good, but you don't pay attention to the properties of the clay, in fact, you only need to solve the problem of gear occlusion, your machine is not only used to make clay tablets, and then a little change, you can transform it into a dough sheeter......"

"Master Hou, what is the dough sheeter?" A group of people suddenly became interested.

"Hehe, many of us love to eat noodles every day, but now the noodles are cut out with a hand rolling knife, today I saw this clay board machine, I suddenly thought of a faster and better way to make noodles, if we replace the dough with live dough and put it in, so that the dough can be pressed into a dough, if we add another drum with a cutter in the back, after the dough is pressed, it will be cut into noodles with the same width and narrowness......"

"Wow, Master Hou's idea is amazing!"

"Yes, yes, in this way, you only need to shake the knob to press out noodles with the same thickness, width and narrowness, which is much more convenient and faster than hand-rolling knife cutting, and you can even open a noodle processing workshop to make noodles, those restaurants and even ordinary families don't have to make noodles by themselves, isn't it much more convenient?"

"Craftsman Liu is going to be developed!"

"Although Hou Ye is only a small change, he has invented a more practical machine, or Hou Ye is smart!"

"Master Hou is naturally smart, where can we compare!"

A group of people began to slap Chen Xu's ass, and Liu Craftsman suddenly became extremely excited from decadence, squatting in front of the machine to look left and right, looking up and down and looking up and down excitedly: "Hou Ye's guidance made his subordinates suddenly, only a small change can be made to make noodles with different widths, narrows and thicknesses, but one more gear transmission is added, the situation is more complicated, if the coordination of the gears can not be completely solved, it is still not easy to make successful!" ”

"So the core problem of all machines is the transmission problem, and the gear is the most commonly used and the most important design, the gear is not successfully developed, all the machines can not do good operation, and the more sophisticated the machine, the higher the requirements for the gear, you still have to organize people to do more research on the gear, this machine is very promising and potential, the creativity is very good, Liu Jiangyan, if you can make this machine successful, I will let the invention and innovation review committee evaluate your invention, I have a good chance of reaching the first prize......"

"First Prize?!"

"Wouldn't that be able to get a prize of 10,000 dollars!"

A room full of people suddenly exclaimed.

"It doesn't matter how much the prize money is, the important thing is that everyone should have this kind of continuous thinking and innovative exploration, Ben Hou is preparing to promote a patent bill next year, once the patent bill can be implemented, all the workshops that want to make and produce this dough sheeter will have to pay a fee to Liu Jiang, called the patent license fee......

"Master Hou, how much is the patent license fee?" A craftsman couldn't help but ask.

"The amount of the patent fee depends on the impact of the invention and innovation on the people's lives, the impact is huge, and the natural patent fee is relatively small, for example, the dough sheeter is not an irreplaceable necessity, and it has little impact on the lives of the people but it is a pure commercial manufacturing and production, so it can be set higher, such as a machine of 100 yuan, if the production of 100 units, then Liu Jiangyan can receive a patent license fee of 10,000 yuan!"

"A hundred is not much, as far as I can see, there are many restaurants and noodle restaurants on the street, and a large number of noodles are sold every day, not including the people who make them at home, I am afraid that Xianyang will be able to sell dozens or hundreds of units by then......"

"Hey~, Craftsman Liu is really going to get rich!"

A group of people bared their teeth again and began to talk about it.

"Linyuan Muyu is better to retreat and close the net, you are all masters hired by the Academy of Sciences, what's the use of envy, in fact, this patent bill treats everyone equally, you can also use your brains to invent and create and even improve some items, if you pass the patent examination in the future, you can naturally be the same as Liu Jiang, sitting at home can count the money and count the cramps of your hands and feet......"

"Master Hou, if this patent bill is really implemented, won't the inventor be able to eat all the food for his children and grandchildren?" A craftsman asked dryly.

"You think too much, everything is constantly developing, new and old things are always constantly updated and replaced, although Liu Craftsman's dough presser is good, but others can also invent a more useful dough sheeter, maybe a few years later, there will be a new and more useful machine, others will not buy Liu Craftsman's dough sheeter, not to mention that each patent is also time-limited, maybe ten or twenty years, the patent license expires, the patent is invalid, so it is natural not to rest on your laurels and want to rely on a patentBut since you have this first patent, you can continue to improve and apply for more patents, so that others have no chance to compete, so the patent bill is a bill that encourages continuous innovation, and you all have the opportunity to sit at home and count the money, but the premise is that you must continue to innovate and come up with practical design products to ......"

Seeing that there were still many people who were ready to speak, Chen Xu waved his hand and said solemnly: "Okay, today is not the time to discuss this topic, everyone should go back to work hard, no invention or creation can be said with your mouth, you must let me and the review committee see the product and see its practical value, otherwise you can only do nothing for the rest of your life!" ”

After Chen Xu finished speaking, he went to another room with his hands behind his back, and several craftsmen and craftsmen followed in, patting his ass as he walked.

"Master Hou, you have a different idea every time, this dough sheeter is so creative!"

Chen Xu walked to a chair and sat down and said, "I just wanted to ask today, how is the compass I asked to make last time improved?" ”

"Master Hou, I have made a lot of compasses, I'll go and get them for you!" A craftsman walked to the front of a cabinet in the room, opened the door and quickly brought a wooden box and placed it on the table.

Chen Xu casually picked up one and opened it, inside was a compass, surrounded by gossip runes such as Qiankun Zhendui, as well as the heavenly stems and terrestrial branches such as A, B, C, D, etc., which indicated the direction, and there was a slender iron sheet two millimeters wide in the center, which was arrow-shaped, and there was a small hole in the center of the iron sheet, which was fixed on the compass with a very thin bamboo wire, and with the rotation of the compass, the central iron sheet would also swing, but it was not as flexible as the compass of later generations, and sometimes it did not turn at all.

This is clearly a defective product.

Open another one, inside is a thin needle, tie a silk thread to the lid of the box, open the thin needle will hang down and cross the air, as the box of fine needles will be deflected left and right, Chen Xu tried for a long time, this should basically be successful, but it is too simple, the silk thread is too thin, the needle is too small, once the silk thread breaks off, it is basically wasted, and it is easy to be damaged in the complex environment of the forest.

There are a total of more than a dozen compasses, basically all of them are still effective, and the production is different, but none of them are visible to Chen Xu.

It's so rudimentary, far from what he imagined.

Looking at Chen Xu's not very satisfied expression, several craftsmen and craftsmen were a little ashamed, and one of them arched his hand and said: "Master Hou, these compasses are made according to the method you mentioned last time, and now there is no shortage of magnets, but the flexible and strong ones are not easy to make, because the pointer is too heavy to rotate, and too light to fix ......"

Chen Xu had no choice, so he had to choose two of them that he felt were relatively sensitive and sturdy.

"The compass is very important in surveying geography and field travel, especially for exploration and military use, so you have to continue to study well, okay, these two can basically meet my needs, this time it is a good job, each person goes to the finance office to receive a bonus of two hundred yuan!"

Chen Xu stood up, took the two compasses and left the Academy of Sciences.

Huaxia is the world's earliest civilization to give birth to a compass, it is rumored that in ancient times, the Yellow Emperor and Chiyou invented the Sinan car in the middle of the war, relying on the guidance of the Sinan car to march to fight, but at that time the Sinan car did not rely on magnets, but the use of pure mechanical principles to drive a pointing instrument on the car to constantly adjust the direction, no matter which direction the car walked, the pointing instrument will always point to the south, so it is called the Sinan car, and Sinan is also an important official position of the march and war, responsible for providing the right direction to the army at any time.

In the Spring and Autumn Period, someone found that the magnet can attract iron, and then there are Fangshi according to this property to polish the magnet to make a magnetic spoon, put it on a smooth plane to rotate, and finally the spoon handle will always point to the south, this is the real compass, one of the four major inventions of the compass also officially appeared.

However, this kind of Sinan is not very effective, because the magnetic spoon is too heavy, and the geomagnetic force in the process of rotation cannot be enough to make it just stop at the position pointing to the south, and the deviation is very large each time, and it can only roughly point to a direction, this simple Sinan equipment Daqin is still in use at the moment, and it can be found in many places, including these craftsmen and craftsmen are good at making Sinan, Chen Xu has tried many times, first through the sun to identify the position of the south, and then repeatedly test the magnetic spoon, but six or seven times out of ten times the pointing deviation is very large, It's just that the general direction is southeast, south, and southwest, and definitely not north.

And go to Zhongnan Mountain, you can't take such an unreliable thing to go, you miss the slightest mistake for a thousand miles, maybe it is not uncommon to die in the end, because it is true that there is little rain in autumn and the field of vision is much wider when the trees are falling, but the problem is that it is easy to fog in autumn, and the situation in the mountains is complicated, and some places are shrouded in fog all day and night, and it is impossible to identify the direction without a familiar guide to lead the way.

Daqin has a population of just over 20 million at the moment, and he usually doesn't meet anyone after leaving the big city, let alone in the reckless mountains.

Last time, I didn't meet two herb-collecting monks, so I guess I would have confessed to it.

After leaving the Academy of Sciences, Chen Xu went out of the city and went to the factory again, and found a large bundle of ropes mixed with cow tendon and twine, as well as various steel objects such as hooks and locks for climbing.

This time into the mountain, you must climb Cuiwei Peak, whether you can find Xia Zijin or not, at least you have to work hard not to regret it, you don't look for your wife if you lose it, a man can't go to this point, although this wife is running by herself, but after all, Chen Xu knows her thoughts, and she also knows the kind of suffering, the water is gentle and not sad to the extreme, and she will never make such a decision, so Chen Xu swore that even if it takes a lifetime, he must find her, let her understand that she really doesn't care if she has children or not.

Because of having children, my father and mother have their own son, and they save money for most of their lives to go to college, and then they hang up not long after graduation, leaving only the old couple sad to despair.

What's more, the current era is not the place he should be.

Knowing the water is gentle, it is his deepest concern after crossing over, this woman is different from all the women he has known in his previous life and this life, not like ordinary human beings at all, and naturally has a kind of love that he can't let go of in the depths of his soul.
