"... The elders have a full understanding of the importance of the optical industry. [Read the latest chapter] As early as during the planning period, under the care of the Executive Committee, it was led by the Ministry of Science and Technology, and the Ministry of Machinery Industry and the Ministry of Metallurgy Cooperating with the Ministry of Light Industry, the time travelers established their own optical industry from scratch..."
Excerpted from "Contemporary Industrial History = Optical Industry Volume"
Of course, readers will simply skip this high-sounding cliché. The first generation of time-travelers all understand the difference between history and official history. The descendants of time-travelers either know the true story from their parents or they don't know it at all. Only those historical researchers who have been granted the highest access to the Grand Library of Vientiane to consult the most original records know the true face of history.
In fact, the Imperial Optical Industry began with just a few pairs of reading glasses.
In the Bairen Industrial Zone, black smoke and white gas billow out day and night, and the wheezing and vibrating sounds of machinery are constant all year round. There is no night here. The light of burning boilers, electric lights and gas lights drive away the night. The rail car driven by the gas engine pulled the flatbed car speeding along the track, making the squeaking sound of brakes from time to time.
In a relatively quiet corner of the industrial zone is the machining workshop directly under the Ministry of Science and Technology. The so-called Science and Technology Department is a "cutting-edge department" under the Manufacturing Directorate.
The so-called cutting-edge, on paper, means that this department is responsible for industrial products that are currently difficult to mass-produce. Travelers are either limited by the supply of raw materials, limited by the performance of self-produced materials, or limited by processing capabilities, and can only use them as "pre-research". To be precise, it is Mōsuo's production technology and technology under the conditions of Lingao's limited industrial level.
Included in the "pre-research" list of the Ministry of Science and Technology are various instruments, precision tools and instruments, optical instruments, communication equipment, power and lighting equipment, timers, etc.
The Ministry of Science and Technology is in charge of Zhong Lishi. His official title is People's Commissar of Science and Technology. He is a doctor. Although he is not the only doctor in the Senate, he always likes to remind everyone that he is a doctor. Over time, everyone is half I jokingly called him Dr. Zhong.
Dr. Zhong’s main focus in the Ministry of Science and Technology is clocks and batteries. Especially batteries, he has in-depth research. Now the wired telegraph sending and receiving systems in Lingao, Hong Kong, Sanya and other places use the Daniel battery or "Zhong's No. 1" battery developed by him.
After the "Zhong's No. 1" battery was successfully put into production, Dr. Zhong's main tasks became timers and radios.
These two projects are among the most urgently needed precision instruments in Lingao's industrial, military and civilian institutions. Navigation requires accurate navigation clocks for navigation positioning and navigation. There is also a great demand for precise timing in industrial production. As for radio, its importance is self-evident. At present, the Senate's expatriates and foreign stations can only rely on radios brought from another time and space to maintain contact with the "center". He devoted all his time and energy to it, and also occupied several science and engineering veterans from the Ministry of Science and Technology, so that several clock towers he promised were used, and the big clocks were no longer used, and each bell tower became empty. The dàngdàng became a watchtower.
After the Ministry of Science and Technology, which had only a small number of personnel and resources, shifted its focus to radios and timers, the optical project became uninterested.
The exclusive workshop area of the Ministry of Science and Technology is near the end of Bairen Industrial Zone. Outside the high wall is a fifty-meter-wide "warning zone" marked with bamboo fences and ditches. Aboriginal people are not allowed to enter the warning zone at will. In order to make full use of the space, the Agriculture Committee will open this plot of land into a field to grow castor, soybean, jute and other cash crops. Most of these cash crops are directly supplied to industrial enterprises. Castor oil, soybean oil and jute are all important materials in industrial production.
"Master, you drink water." In the workshop, a young man in blue cloth work clothes respectfully brought a wooden pallet to another thin black man in blue cloth work clothes who was measuring parts with a vernier caliper. On the tray was a glass bottle of light salt water and a bottle of ice-cold kvass. The thin black man who was called Master responded, wiped the sweat from his forehead with his sleeve, picked up the salt water, raised his head and drank half the cup in one go. He took a breath and drank the rest of the salt water. He picked up the kvass again, but didn't drink it. He just held it in his hand and felt the coldness in his palm.
This kind of enjoyment only started more than ten days ago. After several fights by Dr. Zhong, the Planning Institute finally approved the installation of a small gas cold storage at the location of the Ministry of Science and Technology. There are many more sophisticated equipment and instruments in the Ministry of Science and Technology that require operation at appropriate temperatures. The use of a large amount of ice cubes for physical cooling is essential. . Not only is it time-consuming and laborious to get ice from the large ice warehouse of the food factory every day, but it also consumes a lot of ice on the road. With this icehouse, not only the production needs are met, but also a little enjoyment is provided.
"Junjie, don't be too busy. Let's take a break together. Your health is important in this hot weather." Looking at the young man's work clothes that were blackened with sweat, the thin dark man said.
At the same time, the young man had already removed the tray, picked up a fan and was fanning the master: "I'm not tired, master, please rest."
"Everyone, please take a break." The master picked up the workpiece he had just finished and squinted his eyes to look at the sunlight projected from the skylight carefully.
"The craftsmanship is good. You will be able to do your own job as a fitter in a few years.
"It's all because of the good teachings of the chiefs." The apprentice said respectfully, "My father's craftsmanship is much better than mine. If it weren't for his poor eyesight, he would definitely be better than me."
"It's a pity." The master was silent for a moment. He knew his apprentice's father, who was only a little over 40 years old. Due to long-term malnutrition and heavy labor in the past, his eyesight was already presbyopic.
"Thanks to the chief, otherwise my whole family would have starved to death." The apprentice spoke more respectfully.
The master waved his hand. "Stop talking about this."
He knew that his apprentice's family was a fugitive Shandong craftsman family. The family of six had wandered all the way to Guangdong and became refugees. Only the father and two boys were left. If it were not for the detention at Guangzhou Station, the three members of the family who were already struggling to survive would not be alive today. The eldest child entered the factory as his apprentice, the younger one went to school, and the older one had good skills but poor eyesight, so he could only do what he could in the factory of the Ministry of Light Industry.
After work that day, the master walked in front with his hands behind his back, and the young follower followed behind carrying a bag, a clean lunch box, and a kettle.
"Old Lin! Old Lin!" someone shouted from behind. "Lin Hanlong!"
Lin Hanlong turned around and saw Wu Zijin, a colleague from the Ministry of Science and Technology.
Wu Zijin is a "lut party". Like Mei Lin, Ji Xin, Cui Yunhong and others, he is one of the very few adult male elders who have not bought maids yet - in Lingao... the vast majority of adult elders, including female elders Both purchased maids. So their difference is particularly noticeable. Although the reasons why they don't buy maids are various, some are not "interested" in women, some have temporarily lost interest, some have different aesthetic tastes, and some "would rather solve it by themselves than make do with it"...wait. I'll buy it later when a better maid comes out.
Xiao Bailang got drunk once in a farm cafe, so he gave them a separate party called "Lu Dang". So the term spread.
Wu Zijin was a fresh graduate with a master's degree in electrical engineering in the old time and space. Is specialized in power cables. He has interned in cable factories, transformer factories and substations, and is familiar with the cable production process, but his practical experience is limited and he does not have half a bucket of water. He was messing around in the Ministry of Science and Technology, engaged in "power equipment development." He is also the main player of the Senate Office football team, serving as left back.
Lin Hanlong saw that he was carrying a string bag of dirty clothes, which still exuded a strong smell of sweat.
I remembered that today he went to coach the football team of the Ministry of Science and Technology. Under Chen Sigen's strong advocacy, football, rugby and baseball began to be promoted from schools to various industrial, agricultural and administrative departments.
"Did you watch 88s? The navy guys are clamoring to install fire control systems on ships." He said enthusiastically... "They also want to build mechanical fire control computers! It's really exciting."
"Fire control? We haven't taken out the binoculars yet. It's really an army, a land, a navy and an ocean. We can't keep up with the rapid pace."
"Speaking of which, you majored in optics, right? That's what you do."
Lin Hanlong smiled bitterly. "What haven't I done in Dongguan? Mobile phones, computers, digital cameras... I've made knockoffs of everything. It's not hard to talk about general optical instruments. The problem is that we don't even have optical glass, so what can we do with it? There are already a few decent bureaucrats, it would be nice to be reminded of them after the First Five-Year Plan is completed."
This is not bragging... Lin Hanlong has been working in small electronics factories in the Pearl River Delta for a long time since graduating from a second-rate university. He has worked as an "engineer", "senior engineer", "technical manager", etc. His main job is in various factories in the Pearl River Delta. The copycat electronics factory makes copycat mobile phones, copycat computers, copycat this, and dke that. From notebooks to digital cameras, there are almost no consumer electronics products that he has not worked on. He has also had more or less contact with optical instruments and electronic equipment.
"Isn't there no optical glass? I remember that elders can wear glasses..."
At the time of the time travel, considering that there were many myopics among the elders, although some people had myopia correction surgery before D-Day, many people had doubts about corrective surgery...and were unwilling to go through the trouble. For this reason, when making a list of supplies and equipment to carry, I also specially brought a full set of optometry and mirror grinding equipment and a large number of resin and glass optical lenses. Ensure that a variety of glasses will be available for the patriarch for decades to come. Elders with vision problems often brought enough spare glasses to last a lifetime.
"How many can there be... These optical equipment and supplies are prepared for five hundred people, but now they have to serve hundreds of thousands of people... How can it be enough?"
Lin Hanlong shook his head and said goodbye to Wu Zijin. After returning to the dormitory, he did not eat, bathe, play cards or watch movies. Instead, he ate in a hurry and took out the professional manual that had been dusty for many days and started reading. His maid didn't dare to disturb him, but only filled him with tea and water from time to time.
During lunch break the next day, Lin Hanlong found a piece of glass plate and used it to make flat glass. It was not a rare commodity. It's available in the workshop and warehouse. Lin Hanlong carefully selected, searching almost all the glass plates in the Ministry of Science and Technology's inventory, and selected the clearest glass plate.
Make a scratch with the iron ruler, turn it over and lay it flat on the board, align the scratch with the edge of the board, tap lightly on the long strip of glass and it will come down. Repeat the same process for a few times, and the strip turned into eight one-inch square glass pieces.
In the afternoon, Lin Hanlong found time to take his apprentice to the general material preparation warehouse at the Industrial Port. All kinds of modern materials are under strict supervision by the Planning Institute. No one can take out a screw or a wrench without the signature of some bosses. But the time travelers are much more casual about what they can produce in this time and space.
For ordinary materials in the warehouse, as long as they are below a certain limit, senior industrial personnel can directly fill in the material requisition form and sign for it. As an engineer in the Ministry of Science and Technology, Lin Hanlong often comes to the material preparation warehouse. He nodded to the warehouse manager, and a middle-aged naturalized warehouse manager immediately ran over.
There is no easy job in Lingao. In addition to managing the warehouse, the warehouse manager also has to serve as a porter. When I have free time, I can do some manual work that does not require equipment. All of these are included in the work quota. The former sweatshop manager in the Planning Institute often randomly checks the labor efficiency and workload of various types of work to ensure that no one is having an idle time.
Without waiting for instructions, Lin Hanlong's apprentice pushed a "Zidian modified" to the side and followed Lin Hanlong and the warehouse manager into the warehouse.
The main material preparation warehouse at the Industrial Port used to be just a shed...it was recently renovated into a standard warehouse with a red brick forged iron truss structure. There is also a thermal insulation layer under the top tiles. The sun was scorching outside, and when I walked into the tall and deep warehouse, I immediately felt a chill and my sweat went away a lot.
The material preparation warehouse is internally divided into several sub-warehouses according to the types of materials stored. Wooden and iron shelves are densely arranged and filled with various materials. These are collected, produced and processed in this time and space.
Lin Hanlong knew where what he wanted was. He walked directly to the shelf and pointed at the quantity. The apprentice immediately stepped forward and moved to the car, and the warehouse manager filled out the form accordingly on the writing board. In a short while, Lin Hanlong had gotten everything he wanted. The three of them returned outside the warehouse. Lin Hanlong entered the office with the warehouse manager. The warehouse manager returned to his desk and began to copy the material invoice in triplicate. Someone else came over to serve Lin Hanlong tea, and his apprentice was waiting outside with a cart. After a short time, the material distribution list was copied, and the warehouse manager sent it to Lin Hanlong for his signature, and then presented it to the steward for his seal. In addition, someone is responsible for checking that the quantity and type of items on the material invoice are consistent with the items on the car, and then there are three more chapters.
Back in the workshop, Lin Hanlong told his apprentice that he would work overtime today... and then got down to business. As a generalist, there are countless things waiting for him in the Ministry of Science and Technology. He could only wait until after get off work in the evening to work on this new idea.
The end-of-get off work whistle blew. Lin Hanlong found a suitable gas heating stove and set up an iron pot on it. Put in the iron pot are the beeswax and rosin that you just got, mix them in proportion and put them into the pot. This is the adhesive for the glass.
He turned on the gas fire, patiently waited for the mixture to melt and stirred...then scooped some out with an iron spoon, poured it on a piece of glass, and then pressed it on with another piece of glass. Stick all the glass pieces together in this way.
Lin Hanlong removed the iron pot, added an iron cover to the stove, and took out an iron plate to put it on. Heat the iron plate over low heat. Seeing that the heat was almost done, Lin Hanlong put on heat-proof gloves, put the glass pieces together on the iron plate to let the adhesive melt again, then placed it on the screw press and carefully turned the handle to press the glass pieces together again. Secure with clamps.
While waiting for the glass piece to completely solidify, he went outside to smoke a cigarette and blow in the evening breeze of Lingao. After smoking...I drank another cup of tea.
Finally, all the glass pieces are stuck together...the edges are all aligned, forming a glass cube. After finishing this... he used ink lines to draw cross lines on both ends of the long axis of the cube to find the center, then used an ink circle to draw two circles, one large and one small, and then dripped some melted adhesive and connected the two circles. Small cylindrical iron blocks are glued to both ends of the glass, just covering the small circle of ink lines.
Lin Hanlong asked his apprentice to pack up the stove, and he walked to the grinder with the glass cube. Because it was already off work, no one was using the grinder. From the grinding wheel to the machine, this grinder was brought from old time and space. Lin Hanlong suddenly remembered that Zhong Lishi had said that there were too many things to do about developing grinding wheels at the moment, so we should talk about it later.
He clamped the glass carefully and started the grinder. The first step is to cut off the four edges of the cube, and the cross-section changes from a square to an octagon. Then continue cutting until the octagon becomes a hexagon. It was done very carefully every time, the knife feed was very slow and the coolant was always on. Seeing that it was almost the big circle he had drawn earlier, Lin Hanlong began to rotate the workpiece, and soon grinded out a decent cylindrical shape. He turned off the grinder, took out the workpiece and measured it for a long time. When he was satisfied, he put everything away and called his apprentice to get off work.
On the third day, Lin Hanlong gave his apprentice a task, asking him to use a hammer to smash all the garnets he had received into powder, and then use an iron ball and an iron mortar to grind them as finely as possible. Garnet was discovered by a remote exploration team during field operations. Knowing that it was industrially useful, they brought back dozens of kilograms of samples.
Garnet has relatively high hardness, and ancient people used it as an abrasive to process jade. It is also a gemstone itself.
Gem-quality garnets are mid-to-high-end gemstones. Industrial grade garnet is used in many ways. Because its hardness is 7, it is mainly used for grinding and cutting materials. The remote exploration team mined what could only be regarded as industrial-grade garnet sand. The texture is impure and contains a lot of impurities, and the color is also not pure. To be continued. ! .
