Background

A credit card allows consumers to buy products or services without cash and pay for it later. To qualify for this type of credit, the consumer must open an account with a bank or company that sponsors the card. And then get a line of credit with a specific dollar amount. You can use the card to make purchases from participating shops until you reach that limit. Each month offers a Bill Shepherd, a line card activity during the previous 30 days. Depending on the terms of the card, the customer can pay interest on the amount you were paying on a monthly basis. Also, credit cards may be sponsored by big retailers (such as clothing or department stores) or by banks or companies (such as visa or American Express).

Credit cards are a relatively recent development. Visa, for example, dates back to 1958 when Bank of America started its BankAmericard program. In the mid-1960s, Bank of America began to license banks in the United States the right to issue its own BankAmericards. In 1977 the Visa name has been adopted internationally to cover all these cards. Credit card Visa became the first to be recognized throughout the world.

Banks and corporate sponsors for profit credit cards in three ways. Primarily because they make money from interest payments imposed on the unpaid balance, but it can also make money by charging an annual fee to use the card. Income from these fees, which is usually only $ 50 or $ 75 per client per year, can be significant given that large companies have tens of millions of customers. In addition, the providers make money by charging merchants a small percentage of income to service the card. This arrangement is acceptable to traders because they can allow their customers pay by credit card instead of cash claims. The trader makes arrangements for participation in a credit card with a bank trader, who works with the Bank that issued the card. Commercial Bank determines what percentage of the total value of purchases must be paid by the merchant to the Bank that issued the card. The amount varies depending on the size and type of business, but generally is between 1-2%. A portion of this amount is retained by a commercial bank as transaction processing fee. For companies like American Express that sponsor cards, processing fee may be much higher. Moreover, has the Cowboys generate income through rental equipment check credit cards for merchants (especially if traders can't afford to buy the equipment themselves.) And, finally, the profit had patrons by charging late payment service.

Design

Credit cards are designed with complex security features to prevent potential fraud. These features include a number of card account, sign it, and magnetic tape. Unique card account number is a key part of the information necessary to conduct financial transactions, and must be carefully protected. To prevent anyone from using the wrong account number, or making a false number, companies rely on the laws of statistics. Using the long account numbers that make it unlikely that it can be forged. For example, Visa card has 13 digits, American Express has 15, Diners 14, MasterCard has 20. Mathematically, the nine digits provide unique numbers 1 billion expense (000 million, 000000001, 0000000002, and so forth until 999999999) which will be sufficient for all clients of a particular company. (The biggest companies, visa and MasterCard, only have about 65 million customers.) If set only 65 million number out of possible 10000000000000 possibilities, it is unlikely that anyone will be able to use another account number by mistake. If you enter incorrect account number by mistake by an employee in the store, and almost certainly not be accepted. This gives companies the confidence statistical security there are several when doing business over the phone. Of course, this security measure does not help if someone gets a real number and used fraudulently.

Other feature includes security design signature panel on the back of the card. And aims to sign a document by hand so that the owner can detect the forged signature on receipt. To prevent criminals erase the Backboard from the stolen card and put on their signature, print design with a fingerprint is difficult to replicate and which will bear fruit when the original signature is cleared. If the signature is cleared, this design disappear leaving very white spot, which shows immediately the card was tampered with. Some card manufacturers imprint the word void under the group, which revealed the erasure.

The magnetic strip on the back of the card the third safety feature. The tape is coated with iron oxide particles that can be encoded with binary information, which identifies authentic card. It is difficult to determine exactly what information is encoded on the tape for security reasons companies do not want to discuss this. However, it is likely that the expiry date of the card is one recorded on tape for ATM (ATM) will retain the expired cards. It is unlikely that information such as your credit limit and address, telephone number, employer, be recorded on tape because banks don't reissue cards when changing this kind of information.

Finally, some special features feature cards that make it hard for them to repeat like complex 3D images.

Raw materials

Made of several layers of plastic cards packaged together. Usually consist of a plastic resin core, known as polyvinyl chloride acetate (PVCA). This resin is mixed with shady materials, dyes, plastics to give them proper appearance and consistency. These basic materials unwrapped with thin layers of PVCA or clear plastic material. These slices stick when applied with pressure and heat.

And use a variety of inks or dyes to also print credit cards. It is available in a variety of colors and are designed for use on plastic substrates. Some manufacturers use special magnetic inks to print the magnetic strip on the back of the card. Made of inks by dispersing metal oxide particles in suitable solvents. Additional printing processes involved for cards, such as visa, which features 3D images.

Making

The process

The manufacturing process consists of several steps: first compounded plastic laminate base material encapsulated in paper format. And is printed with the appropriate information. Next slide is applied to the core. Finally, the paper is cut assembled in individual cards.

Plastic molding compounds

1 made of plastic to the background paper about melting and mixing polyvinyl chloride acetate with other additives. Blended items are moved to the extrusion molding machine, which forces the molten plastic through a small opening flat known as die. It comes out the paper die, it goes through a series of three reels stacked on top of each other to pull the sheet along. These rollers keep the flat sheet and keep the paper exits and die, it goes through a series of three reels stacked on top of each other to pull the sheet along. These rollers keep the flat sheet and maintain the correct thickness. Then you may pass papers through additional cooling units before you cut into a separate piece of paper.

The proper thickness. Then you may pass papers through additional cooling units before you cut into separate sheet of saws, scissors, or a hot wire. Paper cut in the Sheet Stacker stacks of them in place and stored for subsequent operations.

2 made of laminate film used to coat the arrow through a similar ejection. These films can be made thinner with the open casting process of dying that spreads the molten plastic film reel casting. Define reel film thickness and width. Cool movies stored on rolls to become ready for use.

Printed

3 basic plastic card is printed with text and graphics. This is done by using a variety of common silk screen operations. In addition, one of the sheet and can also undergo subsequent operations where it is printed with magnetic ink. Alternatively, you can add the magnetic strip on the method of hot stamping. Magnetic heads used to encrypt and decrypt the iron oxide particles can only work if the magnetic medium close to the surface of the card, so the metal particles must be put on top layer Laminating. Upon completion of the printing process, and is willing to be coated.

Plating

4 lamination helps to protect the finish of the card and increases its strength. In this process, paper is fed from the underlying securities through a system of pulleys. And fall a roll of stock laminate over and under securities. These lists feed the sheet into vacuum shoes along with the stock. Void carries three pieces of plastic together as they travel to change direction. Tacking station a pair of Quartz infrared heat lamps warm the upper and lower plastic films. Supports these lamps with reflectors to concentrate the radioactive energy on a narrow area of film, which improves the smooth bonding film to inventory. Then the entire laminate films are bonded to the inventory by pressing metal corridors, which are heated to 266 degrees Fahrenheit (130 degrees) and applied with pressure of 166 lbs/square inch. This process may take up to 3 minutes plating.

Die cutting and embossing

5 after completion of lamination, final assembly is cut and finish the cut ways to die. Each association produces paper, cut into 63 credit cards. This is achieved by cutting for the first time assemble longitudinally to form seven elongated departments. Each of the seven sections are then cut and refinement to form nine credit cards. In subsequent operations, embossed card with account numbers. Then be prepared for shipping finished cards, usually by attaching to e-mail card adhesive paper

Manufacturing

Before the advent of armored vehicles, moving safely and currency and valuables was achieved either through deception or by force of arms. In the case of deception, a postman in civilian clothes carrying valuables disguised as regular package or a small piece of luggage. The courier traveled as a passenger in public transport, and though he was armed, the initial protection lies in appearing to the average traveler. The main limitation of this method size. In order to protect the large shipments of valuables, and adopt a tall man at gunpoint. The first convoys surrounded herself with the armed forces. The Spanish galleon filled with treasure from the new world Defender. In recent times, stagecoaches had closed but far from impregnable strong boxes of metal and wood, while the guardian "rode shot gun" to ward off thieves. E-rail cars equipped with cabinets and was guarded by heavily armed Government forces. This method always fails was twofold. First, although the goods were relatively safe while largely protected, stealth, eventually they need to be placed in smaller cars, and more prone to move it to its destination. Final. The second problem that no matter how many soldiers guarded, swords, guns and cannons or precious cargo travel, greater power of thieves with swords and guns and cannons or can muster To steal goods. As weapons became more compact and bouncing dead, this became more of a problem.

She was inspired by the first attempts at commercial success of armored trucks of military armoured vehicles in the first world war and after the war, noticeable increase in robberies of payroll clerks And messengers bearing deposits resulting from the need for safer ways to transfer money. In 1920, a Chicago area called delivery on the verge of starting school bus security vehicles converted by attaching steel plates for the lower part of the body and prevent the Windows. This was followed by every bus T model cars filled with armed guards. Built the first armored real business that same year in Minneapolis, Minnesota, the Saint Paul police commander turned private detective Mike Sweeney. Sweeney vehicle design in the service of his country Sweeney Detective Bureau.

The first armored car wearing only body paint on steel plates. You may keep your hardwood truck chassises were built. This ended in 1927 when bury thieves explosives in the road and the truck exploded brink and carrying $ 100 in payroll money. In the 1930s and 40s, manufacturers have experimented with aluminum, which has a clear weight advantage on steel. Found metal fatigue and crack after a short time, and was stopped. In the 1970s fuel shortage around the globe spurred manufacturers of plastic shields attempt a lightweight, smaller, more fuel efficient chassises, but the results were similar to those with Traditional aluminum and steel regained control in the industry.

Chassis

1 production of armored heavy truck chassis delivery starts bare. Chassis with the arrival of an entire drive train (engine and transmission), and suspension systems. Some manufacturers receive chassis with a cab, which they cut. Then reuse many pieces. Others use the structure, which topped only with fenders and hood.

Body

2 body is built from an armored truck, much in the same way you framed home. First, put parts of steel pipes box vertically on the table known as the dance represent the individual wall shape. Then (because the cross section looks like a flat brimmed hat) placed steel bars called channel lengths Hat horizontally at specific intervals across the vertical pipe sections and tack welded to hold them in place. Partitions are used to shorten the pipe and hat rail in some areas to leave spaces that will become the Windows and doors. The process is repeated on the appropriate dance for each wall and roof deck, bulkhead.

3 Meanwhile, forming large sheets of solid steel body panels. The leaves are cut first to correct size of massive hydraulic shears. Then rolled plates cut on a table where they are cut slots for Windows and doors with high-temperature plasma torches. Some manufacturers used welding torches to run, while some use a computer controlled robotic arms to deal with blocks. With this automated system, plans on a computer. Then instructs the computer automatic weapons to cut shapes and dimensions to match the plans. Robotic arms slide vertically along the path overhead to achieve vertical cuts, while the rollers in the table cutting steel slide across the torch route to deal with horizontal cuts. Then rolled plates on different hydraulic presses where formed curves and angles. Once the steel has been cut and shaped in an appropriate form, against the corresponding frame and welded or riveted in place.

4 floor building is lifted on the chassis. For the first time put a sheet of hardwood in the temple ' Rails framework to insulate against vibration. Then put the floor on wood and attached to the hull at several points with a number of clamps on form c. The walls and every sublimity and tack welded structure or temporarily clamped so join the Earth, where you meet. Then put a roof over walls. Once the entire structure has been validated for integrity and discretion, and all joints and welds and welded completely or her hopes.

Internal processing

5 now that the body has given its structure, pieces that will make running an armored truck in place. First, quit depending on door frames and hung on doors and modify for righteousness. Armoured doors hung on hinges in a belt, which extends horizontally across the face of the door to support the weight of the plating. Seal grease fittings contain stops to allow doors to swing smoothly.

6 and then foam insulation Board is pressure in the spaces between body panels for steel pipe. Internal paper is then welded steel or riveted on the tube. Some manufacturers use cloth, fiberglass woven roving in a place called ballistic steel interior. Infused layers woven roving with epoxy and put them in a template form internal panels from the truck. The layers are pressed together in a template and when dry, forming a solid piece.

7 once it has lined the Interior, installed in the barrier that separates the taxi from the cargo area. Then install any shelves, boxes, cabinets in the field of shipping, and attached to the roof vents and ports gun installed in doors.

Finishing

8. the first step in creating an armored truck is to grind down any rough or irregular seams and seal any seams with dam. Then you are ready painted Interior and exterior are sprayed with several layers of adhesives and the primer before being drawn according to customer specifications.

9. once the paint is dry, and power cord (running all the wires in an armored truck through the channel exposed for easy maintenance) truck, heating and ventilation engineers installing air conditioning and heating unit Background. Then, you install glass; install locks. And are the mirrors, bumpers, grill guards, and boards. Soft trim interior like seats and belts, masks, doorknobs and last substitution to avoid damage during the workflow. Finally, the truck is driven to paint separate booth spray the underside with infrastructure corrosion resistant.

Manufacturing

Background

The elevator is driven by continuous power, moving stairway designed to transport passengers up and down short vertical distances. Escalators are used throughout the world to move pedestrian traffic in places where elevators would be impractical. Main areas of use include shopping malls, airports and transport networks and business centers, hotels and public buildings. Benefits of the many stairs. They have the ability to move large numbers of people, and can be placed in the same physical space the stairs would be. And had no waiting period, except during heavy traffic. It can be used to guide people toward main exits or special exhibitions. They may be of use in outdoor weather proofed. It is estimated that there are more than 30000 escalators in the United States, there are 90 billion riders travel on escalators in each year. Escalators and their cousins, Weatherly, powered by alternating current motor speed constant and moving at about 1-2 feet (0.3 – 0.6 m) per second. The maximum angle of 30 degrees to the horizontal elevator with high standard up to about 60 feet (18 m).

Thanks to the invention of the elevator in General Charles d. Seeberger, who as an employee in a company Otis elevators, produced the first step of elevator type manufactured for use by the general public. Created in Paris Gallery was installed in 1900, where he won first prize. It also coined the term elevator Seeberger by joining Scala, which is Latin for steps, with a little "lift" in 1910 Seeberger sold patent rights to his invention to the original company Otis elevators. Although there are many improvements, Seeberger basic design is still in use today. It consists of a top and bottom landing platforms connected by metal. Truss contains two tracks, which pull drawer rollaway through endless loop. Truss also supports two handrail, which is coordination of moving at the same speed as the treatment step.

Components

Top and bottom landing platforms

These two platforms are harbouring curved sections of tracks, as well as gears and motors that drive tray. Contains the platform above the cars main drive gear Assembly, while holding the bottom step return idler sprockets. These sections also anchor the ends of the truss lift. In addition, the pads contain a floor plate and plate harrows. Floor panel provides a place for passengers to stand before you step on the escalator. This painting is flush with the finished floor either stops or removable to allow easy access to the machinery below. Comb plate is the piece between the fixed floor Board step transition. And is named because its edge has a series of cleats that resemble the teeth of a comb. These teeth with matching cleats on the edges of the steps. This design is necessary to reduce the gap between class and landing, which helps prevent objects from falling into the void.

Truss

Truss is the structure of a hollow metal plugging lower and upper landing. It consists of two parts joined side along with intersecting arches across the bottom, just below the top. Truss endings are given to the top and bottom landing platforms via steel or concrete support. Truss carries all sections straight path connecting the upper and lower parts.

Tracks

Track system is built on the truss to guide the chain step, which pulls down the steps from the platform down and back up in an endless loop. There are actually two tracks: one for the front wheels of the steps (called the track wheel step) one llalaglat background of steps (called track trailer wheel). Cause the relative positions of these tracks steps to form the stairs as they move from under plate comb. Along the straight segment of truss the tracks are at maximum distance from each other. This configuration forces the back of one step to be at a 90 degree angle to step behind it. This right angle bends the steps in the form of a drawer. At the top and bottom of the escalator, she meets two tracks so that the front and back wheels of the steps are almost in a straight line. This causes the tray to put in order as a flat sheet, one after another, so they can easily travel around the bend in a curved section of track. The tracks carry the steps down along the underside of the truss until it reaches the drop down, where they pass through another curved section of track before leaving the land down. At this point the separate paths and steps carry again if configuration. This cycle is repeated continuously, as steps are pulled from the bottom up and down again.

The steps

The same steps are solid, one piece cast aluminum dies. Rubber mats can be installed to the surface to reduce skidding, you can add yellow seam lines clearly indicate their edges. And cleated on front and back edges of each step with comb-like protrusions that intertwine with the comb plates on top and bottom pads. Correlated steps metal chain going until they form a closed loop with each step able to bend with regard to its neighbours. Front and rear edges of the steps are each connected to two wheels. The rear wheels are set farther apart to fit the track back and front wheels have shorter axles to fit the narrower front track. As described above, the position of controls the direction of steps.

Railing

Railing provides a comfortable handhold for passengers while they ride the elevator. Is constructed of four distinct sections. In the center of the wall is a "slider", also known as "chips" glider, which is a layer of cotton or synthetic fabric. The purpose of the sliding layer is to allow the railway to move smoothly along the track. The next layer, known as tension Member, formed either steel cable or flat steel bar. They provide handrails with the necessary tensile strength and flexibility. On top of internal tension member is building components, which are made from chemically-treated rubber designed to prevent layers from separating. Finally, the outer layer, and the only part that passengers actually see, is a rubber cover, which is a blend of synthetic polymers and rubber. This cover is designed to resist degradation from environmental conditions, mechanical wear and tear and vandalism. Iron is constructed by feeding rubber through computer controlled extrusion machine to produce layers of the desired size and type to match specific orders. The constituent layers are formed from fabric and rubber and steel by skilled workers before being entered into the presses, where fused together. When installed, the final railing is pulled all the way through the chain connected to the engine and the main gear through a series of pulleys.

Design

There are a number of factors affecting the design of escalators, including physical requirements, location, and traffic patterns, safety considerations, and aesthetic preferences. Above all, physical factors such as vertical and horizontal distance to be distributed must be taken into consideration. These factors determine the pitch of the lift and the actual length. Capacity building the infrastructure to support the heavy elements is also critical physical concern. Location is important because escalators should be located where it can be easily seen by the general public. In stores, customers should be able to view the merchandise easily. Furthermore, the up and down movement of the elevator should be separated physically and should not lead to tight spaces.

It must also be expected traffic patterns in the design of the escalators. In some buildings, the goal is simply to move people from one floor to another, but in other cases there may be need for more specific, such as pumping visitors towards the main exit or exhibitions. The number of passengers is important because escalators are designed to withstand the maximum number of people. For example, escalators one offer going quickly to 1.5 feet (0.45 meters) per second can move about 170 people in five minutes. Larger models travel at speeds of up to 2 feet (0.6 meters) per second can handle up to 450 people in the same time period. Absorptive llalmsad must match the expected peak traffic demand. This is critical for applications where sudden increases in the number of passengers. For example, escalators used in train stations must be designed to meet the needs of the traffic peak out from the train, without causing excessive bunching at the entrance to the elevator.

And of course, safety is also a major concern in the design of the escalators. Fire protection is provided by the elevator floor open Add irrigators or fire resistant shutters to open or by installing an elevator in the closed fire-protected Hall. To reduce the risk of overheating, and adequate ventilation must be provided for areas containing motors and gears. Preferably the traditional tray that is located next to the elevator if the elevator is the primary mode of transport between floors. It may be necessary to also provide lift elevator next to the elevator for wheelchairs and disabled. Finally, consideration should be given to the aesthetics of the elevator. Architects and designers can choose from a wide variety of styles and colors laldrabzine and colored side panels.

Making

The process

The first phase of construction of the lift's design mode, as explained above. Elevator manufacturer uses this information to build the equipment according to demand. There are two companies that supply the escalators and primary manufacturers actually build equipment, secondary suppliers to design and install equipment. In most cases, the secondary suppliers get equipment from manufacturers and make adjustments necessary for installation. Therefore, compiling most of the escalators in the main plant. Pulled up the tracks, chains and Assembly, drawer and gears and pulleys each mechanism in place on the truss before shipping.

Before installation, you must be prepared for landing areas to call the elevator. For example, you should pour concrete equipment, and must attach a steel frame that will hold the truss in place. After delivery of the elevator, and full uncrated Assembly and steer clear of attitude between the top and bottom holes. There are a variety of ways to lift the truss Assembly in place, one of which is the scissors lift mounted devices on wheeled support platform. It is equipped for a specific association with scissor to assist in vertical and angular alignment of the elevator. With this device, at the upper end of the truss can easily align with and support of the upper landing associated support wall. The lower end of the truss can be lowered later in the hole associated with landing ground below. In some cases, it may be shipped separately from the rest of the wall. In such a case, and she coiled carefully and packed for shipment. And then delivered to the appropriate strings after installing the elevator.

Ultimate connections for power source and check to make sure that all paths and strings correctly.

Quality control

The Federal Regulation Act (CFR) contains guidelines for quality control elevator and puts the minimum inspection criteria. As stated in the code, elevators and escalators are thoroughly inspected at intervals of not more than one year, should additional monthly inspection for satisfactory operation of certain people."Annual inspection records are posted near the elevator or be available at the station. In addition, the law determines that the maximum load of the elevator and glue and not exceeded. And additional safety standards can also be found in the American Society of mechanical engineers.

The future

And has made many innovations in the manufacture of escalators in recent years. For example, one company recently placed elevator spiral staircase. Another has developed a lift suitable for wheelchairs. And is likely to continue with the expansion of the industry to meet the changing needs of the market. In addition, the industry expects growth spurt of untapped markets like China and Hungary begin to recognize the benefits of elevator technology.
