What gadgets have changed people's lives?

zipper

Also called zipper. It is one of the important inventions that facilitate people's lives in modern times, and it is called the smallest and most practical invention!

The appearance of zipper was a century ago. At that time, in some places in Central Europe, people tried to replace buttons and bows with belts, hooks and rings, so they began to experiment with zippers.

1893, an American engineer named Judson developed a "zipper" and obtained a patent, which is the initial prototype of the zipper. The appearance of this device has an impact on the button hooks used in high boots. However, this invention did not catch on quickly, mainly because the quality of this early locking device was not good enough, and it was easy to loosen at an inappropriate time and place, which was embarrassing.

19 13 years, Sambak, Sweden improved this rough locking device and made it a reliable commodity. The method he adopted was to connect the metal lock teeth to a flexible shaft. The working principle of this zipper is that each tooth is a small hook, which can be matched with the small hole under a small tooth on the next belt and the opposite belt. This kind of zipper is so strong that it can only be opened by sliding the slider to open the teeth.

Zippers were first used in military uniforms. During World War I, the US Army first ordered a large number of zippers to make clothes for soldiers. However, the promotion of zipper in the folk was relatively late, and it was not until 1930 that it was accepted by women to replace the buttons of clothing.

The zipper has its current name at 1926. It is reported that the novelist Francot said at a business luncheon to promote a zipper sample, "Pull it and it will open! Pull it again and it will close! " The characteristics of zipper are explained very concisely. The word zipper comes from this.

In Ando's own words, the invention of instant noodles is "an inspiration born of hunger". Ando is not a Japanese. 19 10 was born in Taiwan Province province, China, formerly known as Wu Baifu. I lost my parents since I was a child, but my father's legacy provided Ando with enough venture capital. He learned the experience of running a silk shop from his grandfather. At first, he made a fortune by selling knitwear, and 1933 came to Japan across the ocean, and his career was quite successful.

instant noodle

Before and after World War II, Japan faced a serious food shortage, and people were so hungry that they even ate potatoes and seedlings. It was during this period that Ando began to believe that "with enough food, the world would be peaceful". The so-called "full", so I decided to join the food industry.

One morning, Ando passed a Lamian Noodles stall. Although it's still early, there is a long queue of twenty or thirty meters in front of the booth, and people are waiting for Lamian Noodles to cook in the cold wind. Standing opposite the Lamian Noodles stand, Ando thought, if there is a kind of noodles, just rinse them with boiling water and you can eat them. I guess everyone will like it. Think about it, Ando didn't immediately develop instant noodles.

From 65438 to 0948, Ando founded Zhongjiao Food Company and began to engage in the research of nutritious food. He used high temperature and high pressure to extract the thick juice of stewed beef and chicken bones to make nutritional supplements. As soon as the product went on the market, it was deeply loved by the Japanese, and Ando became a celebrity in the Japanese food industry. The production of nutritional supplements laid a foundation for the development of instant noodle seasoning in the future.

Unforeseen things happened. An accident in the 1950s made Ando lose almost all his property and had to start a business from scratch. At this time, the idea of producing instant noodles flashed through his mind again, and he began to have an indissoluble bond with instant noodles for decades.

The wife cooks and inspires cooking, and the son is afraid that chicken will lead to chicken juice.

1958 In the spring, Ando built a simple hut in the backyard of his home in Osaka, which was less than 10 square meter and was used as an instant noodle research room. He found an old chef who made noodles, bought a wok with a diameter of 1 m, flour, cooking oil and other raw materials, plunged into the wooden house and began various experiments before the advent of instant noodles.

Noodles seem simple, but the ingredients are subtle, and Ando is a complete layman, which adds a lot of difficulty to his experiment. He took everything he could think of to the noodle manufacturer for testing. As a result, some noodles were loose and some stuck together. He just threw it away, threw it away and did it. Repeat it over and over again.

The experiment made Ando a little obsessed. Once at the dinner table, his wife cooked a delicious stir-fry dish, from which he suddenly realized a trick of making instant noodles: frying. Noodles are mixed with water, and water will be released when frying, so there will be countless holes on the surface of fried noodles. After adding boiling water, noodles will become soft like sponges. In this way, noodles are soaked in soup to make them tasty, then fried and dried to make noodles that can be preserved and brewed with boiling water. This practice was called "instant hot oil drying method" by him, and he soon got the patent of instant noodles.

18 12, canned.

The first batch of cans appeared in 18 12 and the first can opener appeared in 1885. Although it was troublesome to open cans at first, it became a long-term food storage vessel in the kitchen, bringing summer dishes to the table in lifeless winter. Legend has it that Napoleon once offered a reward for talent, and whoever can provide the army with food that can be stored for a long time will be rewarded. 1795, French brewer Nicolas? Abel uses high-temperature sterilization and sealed storage to store food in cans, but he doesn't know the principle of disinfection. By 1809, his factory began to supply canned food to ports all over France. Golden soup in London? Hall and Gambao applied his method to tin cans, which was our preferred food storage method later.

185 1 year, sewing machine

1830, when the French tailor bartholomew? When Lemont patented the first sewing machine, his colleagues thought they would become obsolete; This new machine can sew 200 stitches per minute, while manual sewing can only sew 30 stitches per minute. 184 1 year, they looted Timoni's shop in Paris. Therefore, the honor of leading the automation of the clothing industry falls on the son of a German-American immigrant, Isaac? Mei Lite? Singh, 185 1 who improved elias? Howe's early design. 1856, Singh was the first to put forward the method of installment payment, so that people could afford sewing machines.

1854, elevator

A 40-year-old unsuccessful mechanic, with a neat moustache and a top hat, stood on a platform. This platform is hung high by a cable wound around a drive shaft and above the audience attending the new york Expo 1854. Suddenly, Eliza? Graves? Oddis ordered the cable to be cut. The audience held their breath. The platform dropped a few feet and then stopped. Oddis took off his hat and cheered, "completely safe, gentlemen, completely safe." The elevator was born in this city.

The elevator had already appeared before this. But Oddis designed a kind of spring, and put two Kouga in the V-shaped cut of the slide to prevent the cable from breaking, so he built the world's first safety elevator.
