Reborn in 1977

Chapter 273 Martial Arts Manual

Chen Fan wanted to buy rivets, not to repair circuit boards, but to make saddles and belts.

Using rivets to fix leather and boards, as well as connecting points for belts, is very good and better than ordinary nails. Especially using large rivets to punch holes in the belt looks even better. That's why he wanted to buy some rivets to make the saddle and belt better.

Unexpectedly, he heard such words from Wang Xiaoling.

This made him a little numb.

He didn't buy the rivets, but he bought some distiller's yeast, including daqu, xiaoqu, hongqu, maiqu, and fuqu. These days, many people brew their own wine, so the supply and marketing cooperative has enough distiller's yeast, which is very convenient to buy.

Daqu and xiaoqu are used to brew baijiu, while hongqu and maiqu can be used to brew yellow wine. In addition, hongqu can also be used to make fermented bean curd and cherry meat. Fuqu is a good material for brewing sauce-flavored liquor and can also be used to brew beer, so Chen Fan bought some of each.

He hadn't started brewing wine with the miscellaneous grains he brought back last time, originally planning to wait until he was done with this busy period.

However, when wiping Jiang Lili's wound today, he didn't have high-proof alcohol, so he could only use Yunhu Daqu, which was expensive and not as effective as alcohol. He might as well start brewing earlier and collect some alcohol for later use. Brewing wine became a side benefit.

He also wanted to buy some reagents to test for methanol, but the supply and marketing cooperative didn't have them. He would have to go to a special chemical store, which he would have to buy in the county town, so he could only wait until later.

Anyway, the boiling point of methanol is 64 degrees, and the boiling point of ethanol is 75 degrees. When the time comes, he would cut off the heads and tails and process it slightly, which shouldn't be a big problem.

If it really doesn't work, he would store it in a cellar for a year to ensure that all the methanol evaporates completely.

......

Coming out of the supply and marketing cooperative, Chen Fan rode his horse slowly towards the scrap recycling station.

The reason for the slowness was because he was thinking about the relationship between rivets and circuit boards.

It must be said that when the spirit is high, the brain is easy to use. Many things can be recalled as long as you think about them carefully.

Moreover, he majored in mechatronics in college, so he is no stranger to circuit boards. He also played with vacuum tubes and diode old machines in school. After careful recollection, he really remembered something.

Rivets are indeed an indispensable component of early circuit boards, but he just didn't pay attention to them before.

A long time ago, PCB printed circuit technology was not yet popular. Most of the vacuum tube radios in the 1940s and 1950s used the shed strip method to solder circuits.

The so-called shed strip is to weld electronic components on a board to form a circuit. If the printed circuit board is regarded as a plane, then the shed strip is three-dimensional. From the perspective of later generations, no one would think that it is a circuit board.

Among them, the parts that fix the metal lugs of some electronic components on the board are rivets, and their function is equivalent to the solder joints of later printed circuit boards.

If it's just like this, it still doesn't show the importance of rivets to circuit boards.

As time went by, in the 1960s, transistors began to gradually replace vacuum tubes and become the mainstream components of radios and other electrical appliances. However, due to the lack of follow-up in technology, many of the electrical appliance manufacturing technologies at that time followed the assembly method of vacuum tubes, and even the movement was designed according to the movement of vacuum tubes.

This gave many electronics enthusiasts DIY space, and many radio equipment stores emerged.

At that time, a high-frequency triode cost more than two yuan, and a genuine Soviet-made tube 401, called 3AG1 in China, cost 6 yuan and 3 cents. A film triplex also cost five or six yuan. The smaller the electronic components, the more expensive they were, and the larger ones were cheaper.

After buying these high-priced electronic components, they had to be fixed on the circuit board and a metal wire was used to form a circuit to be considered a complete circuit board.

The most critical connection point is the rivet.

At that time, a kind of board was popular, called "hole board", also called "universal board", and even now some electronics enthusiasts are using it.

In fact, it is a board with N small holes neatly arranged on it. Those holes are convenient for riveting. The rivets are used to connect various electronic components with metal wires to form a complete circuit, which is a "circuit board".

In response to this electronic DIY trend, even professional magazines have joined in to provide technical guidance.

(Radio magazine in the 1960s, analyzing the circuit board of a radio, the white small round holes on the brown board are rivets)

The expensive price of radios and the simple assembly process made many people choose to assemble a radio by themselves. Rivets were also classified into the category of electronic components and appeared openly in electronic equipment stores, rather than hardware stores or supply and marketing cooperatives.

After figuring out the reason, Chen Fan thought about going to the county sometime.

He hadn't been to the county yet, and he didn't know what the county town was like in this era. At least there should be a movie theater, right?

Speaking of which, Nanhuzhen is not small, with a dozen or so large and small units. Cough cough, although most of them are small workshops, isn't there still a "large enterprise" like the waterway transportation company, but there isn't even a movie theater, which is really stingy.

Secretly complaining, he soon arrived at the scrap recycling station.

This was his second time here. Last time, he went to the market in December, thinking that the protagonists written in the novels were picking up bargains at the scrap station, so he also ran to pick up bargains, but he didn't even have a funnel.

Today, he naturally didn't want to pick up bargains, he just wanted to buy some scrap iron and scrap copper.

As soon as he got off his horse, the people at the scrap recycling station greeted him.

Although this is just a small scrap recycling station, there are 3 people working there.

One is weighing and receiving goods, one is bookkeeping and cashier, and the other is the director who doesn't know what he does and sits in the office. The sparrow is small, but it has all the necessary organs.

Seeing Chen Fan dismount at the entrance of the scrap station, the bookkeeper sitting in the innermost part of the store immediately shouted, "Director, Teacher Chen is here."

The uncle in charge of receiving and weighing goods at the door had already greeted him, grinning like he had seen a relative, "Teacher Chen is here, I heard that your article was published in the newspaper?"

This attitude is a world of difference from the last time.

Chen Fan estimated that he was semi-literate, otherwise he wouldn't even be able to distinguish between newspapers and magazines.

The thought flashed through his mind, then he regained his thoughts, took out a cigarette and greeted the weigher he didn't know, "Haha, it's just a small matter, even you know about it."

Thinking in his heart, this time the attitude is different from the last time, but how did they recognize me?

The weigher pointed to the little mare next to him and said with a smile, "You are the only one in the whole commune who rides a horse without a saddle, and the horse is so handsome, and the age and appearance are similar, it would be strange if I couldn't recognize you."

Chen Fan turned to look at the little mare, so it was you who betrayed me?!

The little mare snorted, "What?"

At this time, two more people came out from inside. Chen Fan immediately handed over two cigarettes and smiled at an uncle in a Zhongshan suit, "You should be the director, hello, I want to buy some scrap iron and scrap copper, I don't know if it's convenient."

The weigher immediately introduced from the side, "This is our Director Fang, this is Accountant Wu."

Chen Fan greeted again, "Director Fang, Accountant Wu."

Director Fang took the cigarette, his face blooming with a smile, "Teacher Chen is polite. I don't know how much scrap iron and scrap copper you want to buy?"

Chen Fan smiled, "Not much, just a few pounds of each, but it's best if the quality is better."

Director Fang said nothing, turned around and walked inside, "There must be a few pounds, the best scrap iron is the iron from the shipyard, especially the one from the engine room, which is harder than the deck iron. The quality is definitely guaranteed. As for copper, do you want copper or brass? If you want large pieces, there is only brass, and copper only has small pieces."

Chen Fan followed him, preparing to go to see the scrap piled up in the corner of the store, but found that Director Fang was still walking inside.

He suddenly realized, no wonder he didn't have anything last time, so it's just a scrap recycling station, and there's a damn small warehouse???

Passing through an office, and then out the back door, there was a small courtyard behind, and there was even a small house in the courtyard.

Director Fang led him directly to the front of the room inside, unlocking the door as he spoke, "The more valuable items are stored here. Generally, they're not sold externally but sent to the county, sorted, and handed over. Then, the county headquarters allocates them to the relevant units. If the county units don't need them, they're sent to the prefectural committee to support national construction."

As he spoke, he pushed open the door, glanced back, and smiled, "But others can't, Teacher Chen certainly is an exception. Even if the leaders come, they wouldn't say anything. It's rare for you to come, so come in and see for yourself. Take whatever you need, and we'll settle the bill together later."

Chen Fan, with a face full of smiles, offered another cigarette, "Thank you, thank you."

I'll just believe these polite words for now.

Following Director Fang through the door, Chen Fan looked around, his head swiveling. The room wasn't large, but it was packed with items.

The iron pieces in one box didn't look simple. Tapping them lightly, they rang out with a clanging sound, indicating good toughness. The iron pieces were also covered with a layer of uncleaned black oil.

There were also several shelves with copper parts, which appeared to have been removed from machines. Among them was a bundle of copper wire. Although it had been scrubbed, stains could still be seen in the gaps. It was unclear which machine it came from.

Although he had studied mechanics, he wasn't familiar with the old antiques of this era and couldn't identify what the parts were.

Director Fang smoked his cigarette to the side, not saying much and letting him choose for himself.

Chen Fan's gaze then fell on the half-box of old books in the corner. He turned his head, his face full of surprise, "Director Fang, can these old books be bought as well?"

Director Fang laughed heartily, "It's the same saying, others can't, but Teacher Chen can."

Chen Fan's eyes twitched slightly. The last time he came, the people at your store didn't say that.

When he asked about old books then, they directly said they didn't have any.

However, he could tell that Director Fang's words were much more sincere than before, so these old books must be something special. He curiously asked, "Aren't these old books going to be pulped for papermaking?"

Director Fang shook his head and said with a smile, "These old books are different from waste paper. They are first sent to the county waste company and combined with old books from all the communes. The library selects from them first, and if they find something they don't have, they'll take it. Then, the Xinhua Bookstore selects a second time.

Some people in the county don't have jobs, and they're too old to work in factories, so they're affiliated with the subdistrict office, allowing them to open used book stalls to rent out books for a living. Their superior is the Xinhua Bookstore, and their books are basically sourced from there. However, new books are too expensive, even children's books cost a dime or two, and big volumes can easily cost one or two yuan, or even four or five, so the subdistrict office discussed with the waste company to make use of the old books and wholesale them to them.

The remaining books that no one wants are then pulped for papermaking."

Chen Fan suddenly understood. At this moment, he also vaguely remembered his grandfather saying that a cadre who had left the village used to work at a waste company in Yunhu, and he had handled old books at the time.

Unlike what many people online say in later generations, this era didn't forbid this or that. As long as the books weren't too special, like Lanling Xiaoxiaosheng's works, no one really cared.

Ahem, actually, even if you really wanted to read them, no one would care. It's not like anyone would do something that hurts others and doesn't benefit themselves unless they had a grudge.

Of course, grudges are another matter.

But one thing is true, the variety of books in this era is really small. Because the creation of literary works has almost come to a standstill, with only a few writers still writing and the themes being very limited, it gives people the feeling that reading is restricted.

Understanding that these books could be bought, Chen Fan immediately pounced over.

Then, he was disappointed.

There weren't many books, only half a box, and most of them were elementary school textbooks, which were useless. If they were middle school textbooks, he would be willing to buy them back for Jiang Lili and the others to use, but elementary school textbooks were out of the question.

Then there were some tattered works of literature of the era, which weren't of much value.

However, based on the principle of never returning empty-handed, he still tried hard to find two books from them.

One was a songbook, with musical scores, which could be used to practice the harmonica.

The other was actually a martial arts manual, Tai Chi Quan, have you heard of it?!

Chen Fan curiously flipped through it, "Tai Chi Quan Movement" published in 1962. He wondered if there were any secret techniques inside?

(1962 edition of "Tai Chi Quan Movement", priced at 0.6 yuan)

Captain Xiao taught him the Xingyi spear power, which he had already thoroughly understood, so now he could only buy some books to read himself, which was also embarrassing.

However, he himself was clear that this kind of publicly published "martial arts manual" was almost impossible to have any secret techniques. As expected, this book didn't have any, just some moves and footwork, without involving any power. He would just consider it broadening his horizons.

After taking two books and selecting some iron pieces and copper parts of different sizes, he went out to settle the bill.

The weigher in front didn't distinguish between copper and iron, throwing them directly onto the scale and randomly reporting a number, "10 jin."

Chen Fan glanced at him, confirming that copper and iron were the same price?

Then he glanced at the scale. Good heavens, the weight had been pushed all the way to the iron bar above. It was estimated that it could be at least two more jin.

Director Fang turned a blind eye to the weight on the scale and waved his hand to the side, "Xiao Wu, issue the invoice, 10 jin of scrap iron ex-warehouse."

As for the two books, he didn't mention them at all. In addition, he gave away a patched burlap sack for free, stuffing all the copper and iron into it.

Chen Fan could only express his gratitude for the kindness and gladly accept it, paying 3 yuan and walking away with the sack.

Then he sighed inwardly, scrap iron is really expensive.

… …

After buying the things, he rode his horse to Team 7.

Speeding along the main road of Lujiawan, the commune members who were transplanting rice in the rice paddies on both sides stopped to watch.

"Oh, where is Teacher Chen going?"

"He's very busy all day long, running between Team 6, the brigade, and the commune. Maybe he has something to do again."

But no one mentioned Teacher Chen's work being published in the magazine, because they didn't know yet.

The town had postmen helping to promote it, but in the production team, he only ran to the brigade headquarters, so the news hadn't spread yet. However, in two days, everyone in the entire brigade would definitely know, and he might even become famous throughout the entire commune. Teacher Chen was about to become famous in Nanhai again.

They didn't know about the magazine, but they had heard gossip about Team 6.

"Hey, hey, hey, have you heard? Something big happened in Team 6 today."

"What big thing?"

"It's that educated youth girl, she punctured her foot while transplanting rice."

"What's so big about that? The year before last, before I went to the fields, I stepped on a rock and got a big cut, which delayed me for several days. Transplanting rice earns male workers 12 points a day, and female workers get 10 points, a huge loss."

"That's not the point, she can't explain it clearly, let me tell you. Do you know, Teacher Chen carried that educated youth girl."

As soon as the words fell, there were exclamations of surprise.

Dozens of people around looked at that person, and someone immediately shouted, "Tell us quickly, what's the matter?"

"It's that educated youth girl, didn't she puncture her foot? Then, Teacher Chen happened to pass by, and without saying a word, he rode his horse over. That's a field ridge, less than a meter wide, and he dared to ride a horse on it. How anxious do you think he was?

That's not all, when he got to the edge of the field, he jumped down, ran into the field without taking off his shoes, picked up that educated youth girl and rushed back. Tell me, is there something going on between them? !"

There was a chorus of whispers around.

"Is it true, without taking off his shoes?"

"You can ride a horse on such a narrow field ridge? I'm afraid that's nonsense."

"There were so many people transplanting rice, even if they had something going on, they wouldn't hug like that in public, it must be fake."

At this time, the eldest sister who first revealed the gossip finally seized the opportunity and shouted loudly, "It's fake, the third daughter of Lao Wang next door to me is married to Team 6, she was there at the time, and she went back to her mother's house at noon today, and that's what I heard her say. Teacher Chen took off his shoes before going into the field…"

Another eldest sister disagreed, "My third sister went to Team 6 today and heard it with her own ears, so it can't be fake, he definitely didn't take them off."

"Took them off!"

"Didn't take them off… definitely didn't take them off."

"Definitely took them off…"

… …

Chen Fan didn't know that half of the brigade was discussing the issue of whether he took them off or not, only caring about riding his horse quickly to Team 7, buying more than 3 jin of fresh milk from their Captain Tang Xianjun, giving him a yuan, and then carrying the milk in a bamboo tube home, preparing to make a cake.
