2. Civil aviation air mask
(1 Introduction
Upon passenger planes, oxygen masks are emergency rescue devices that provide passengers with oxygen. Should the cabin suddenly loses airtightness or perhaps encounters other hypoxic problems, passengers can get breathable oxygen masks to supplement oxygen at any time. After the aircraft reaches a certain altitude, pressurize the log home. If the aircraft log home loses pressure, it may cause hypoxia, and passengers may feel dizzy, lose brain, and even endanger their lives within the absence of oxygen. Individual cabin depressurization at numerous altitudes, the duration of hypoxia that an individual may withstand is different. The more expensive the flight altitude, the actual less time to stand up to. In civil aviation airliners, each person’s seat provides you with a personal oxygen mask for emergency use, so you don't have need to fight avoiding pulling the oxygen disguise and delaying use.
(2) Construction principle
The oxygen mask is connected to the automatic coupling through a slender rubber oxygen supply tube along with a bayonet joint. Oxygen continuously flows to the air storage bag from the mask. The gas storage space bag first stores fuel, and then when the item expands, it can hold plenty of oxygen. When the passenger calls for a deep breath to empty the air storage bag, the air intake valve on the mask can allow oxygen to enter.
(3) How you can use
In the event of decompression in the aircraft cabin, the oxygen mask could automatically be thrown down from your cabin roof. Above the actual passenger seat, there is definitely emergency manual release in the oxygen mask with some sort of "push" mark. After moving open, the oxygen mask will automatically lower while you're watching passengers. On the relieve board, there are graphics and text instructions on the right way to use it. Passengers will need to follow the instructions appropriately.
In summary, oxygen masks play a key role in assisting treating diseases and protecting the actual safety of passengers.

Laser cleaning There are various cleaning methods while in the traditional cleaning industry, almost all of which use chemical agents and mechanical means of cleaning. How to find the cleaner and non-damaging clean-up method is a problem we must consider. Laser cleaning has the characteristics of non-grinding, non-contact, non-thermal consequence, and suitable for physical objects of various materials, and is considered to be the most reliable along with effective solution. At once, laser cleaning can solve problems that can't be solved by traditional cleaning methods. For example, when you will discover sub-micron pollution particles about the surface of the workpiece, these particles have a tendency to stick very tightly. Normal cleaning methods cannot take away them. However, it is extremely effective to clean the surface belonging to the workpiece with nanolaser radiation. Likewise, because the laser washes the workpiece without call, it is very safe to scrub the precision workpiece or perhaps its fine parts, and its accuracy may be ensured. Therefore, laser cleaning has unique advantages from the cleaning industry.
Compared with traditional cleaning methods just like mechanical friction cleaning, substance corrosion cleaning, liquid-solid sturdy impact cleaning, and high-frequency ultrasonic cleansing, laser cleaning has clear advantages.
1 "Laser cleaning is usually a "green" cleaning method that would not need to use any chemicals and cleaning liquids. The cleaned waste is solid powder, small bigger, easy to store, recyclable, allowing it to easily solve chemical cleanup. Environmental pollution caused through;
2 The traditional cleaning method is frequently contact cleaning, which has mechanical force about the surface of the cleansing object, damages the surface belonging to the object or the cleaning medium adheres for the surface of the object to be cleaned, and cannot often be removed, resulting in legitimate pollution. Grinding and non-contact can easily solve these problems;
3 Laser might be transmitted through optical fibers, coordinated with robots and also robots, it is convenient to understand long-distance operation, and can clean parts that happen to be not easily reached by means of traditional methods. This can ensure the actual safety of personnel when utilised in some dangerous places;
4 Laser cleaning can remove various kinds of contaminants on your surface of various materials to realize the cleanliness that cannot be achieved by conventional maintaining. And it can also selectively clean the contaminants about the surface of the materials without damaging the surface of the material;
5 Laser cleaning efficiency is high, saving moment;
6 Although the initial investment within the laser cleaning system will be relatively high, the cleaning system work extremely well stably for an extended time, with low operating costs and only electricity bills per hour.

This overlock sewing machine is a kind of sewing machine. After the Industrial Revolution in the center of the 18th century, the large-scale production belonging to the textile industry promoted that invention and development belonging to the sewing machine. There is a document that this Germans registered a patent for sewing machines in britain in 1755, but there isn't any research evidence. In 1790, British woodworker Thomas Sainty very first invented the world's initial single-thread chain stitch hand sewing machine in making holes, threading, and sewing leather shoes. In 1841, French tailor B. Timonier (Barthelemy Thimonnier) (also translated seeing that Barthelemy Dimonnier) invented and also manufactured a chain stitch sewing machine that has a needle and a hook. In 1845, Elias Howe (also translated since Elias Howe) also individually invented the sewing device. In 1851, the U . s citizens mechanic I. M. Vocalist (also translated as Lechak Merritt Singer) formulated the lockstitch sewing machines and founded the Singer company. Sewing machines on this period were basically hand-cranked. Around 1859, Singer invented that pedal sewing machine. Once Thomas Edison invented this electric motor, in 1889, Vocalist invented the electric motor-driven stitching machine. Since then, an innovative era in the sewing machine industry is created.
Overlock sewing machines can also be called sidecars, side stitching machines, and bone autos, generally divided into 3 lines, four lines, and five lines. The main function is mostly to prevent the sewing from the garment from fuzzing. The overlock sewing machine work extremely well not only for hemming, but also for sewing T-shirts, sportswear, under garment, knitting and other material. Overlock sewing machine cutting and sewing might be carried out simultaneously, the stitch is being a mesh, and it is likewise suitable for elastic material.
Overlock stitches can be divided into single line, double thread, three line, four thread, five thread, etc.
1. Single-thread overlock can be a single-needle, one-thread stitch, that is certainly mainly used to sew the actual edges of blankets;
2. The double-thread overlock is often a single-needle double-thread stitch, that is certainly mainly used to sew components with large elasticity, including bottom edge of a new stretch shirt;
3. The three-thread overlock stitch may be a single-needle three-thread stitch, that is certainly a common stitch regarding ordinary knitted garments, specifically the stitching of a crowd of low-grade garment pieces;
FIVE. The four-thread overlock stitch is often a double-needle four-thread stitch. Balanced with the three-thread overlock stitch, any needle thread is added, and the strength will be improved. It is used regarding sewing the garment portions of higher-grade garments or endures more stretching and robust friction. Parts such while shoulder-fitting and sleeve-fitting, especially the sewing of outside garments;
5. The five-thread overlock stitch is usually a double-needle five-thread stitch, and also its stitch fastness along with production efficiency are further improved, and its elasticity is superior to four-thread overlock stitch. It is often used for stitching outerwear and trimming under garments.
