To connect a tube to an installation or to connect two tubes to each other, it is known to use rigid endpieces of the spigot type having Christmas-tree shaped teeth, in which the rigid endpiece possesses a cylindrical tubular portion fitted on its outside surface with catching sharp edges that retain the tube and that seal the connection once the cylindrical portion has been forced into the tube. The main drawback of such a device lies in difficulties associated with assembly and disassembly. In order to guarantee good retention and good sealing, the teeth must be of sufficient height to bite properly into the inside surface of the tube, and as a result hand assembly becomes extremely difficult since it is necessary to develop large engagement forces, and disassembly becomes practically impossible because the teeth penetrate into the inside wall of the tube and their substantially radial surfaces oppose a force tending to pull them out.
In certain applications, it is nevertheless useful to be able periodically to make and break connections between a tube to a rigid endpiece easily and by hand. This can be made easy by significantly reducing the height of the teeth, however that is to the detriment of the quality of retention and of sealing achieved between the endpiece and the tube.
To remedy this drawback, is it known to band the tube, once installed on the endpiece, with at least one collar or ring that is placed on the outside of the tube and that is clamped thereon by appropriate means.
Such devices provide mechanical qualities that are satisfactory, however connection and disconnection operations require enough time to operate the clamping means. Further, when connection and disconnection are frequent, the indentations formed repetitively by the collar in the tube end up by damaging the outside surface thereof and can lead to a weakening in the retention provided by the banding collar on the tube.
Quick coupling devices are also known for coupling a tube to a rigid endpiece, which devices comprise a female part secured to the rigid endpiece and a male tubular part fitted to the end of the tube to be coupled. The female part has a stepped bore including a large diameter portion capable of receiving a shoulder of the male part beyond an axial latch. The male part generally has an elongate portion with a cylindrical outside surface fitted with retention projections (e.g., Christmas-tree shaped teeth) for providing non-dismountable connection between the tube and the male part.
With that kind of device, initial coupling takes place in two stages. The tube must first be fitted on the male part and this requires large engagement force since the clamping must be strong enough to ensure that the connection is leakproof. Thereafter, the male part must be inserted into the female part until the shoulder of the male part has gone past the axial latch of the female part, with the connection being sealed by means of O-rings disposed between the two parts. The tube is disconnected by acting on the axial latch so as to decouple the male part from the female part.
That kind of device thus makes it possible to perform frequent connections and disconnections without damaging the mechanical qualities of the coupling formed. However, the structure comprising two separate male and female parts is inconvenient in use and initial coupling requires special tooling and handling for the purpose of engaging the tube on the male part.
U.S. Pat. No. 5,314,216, issued to UMEZAWA for THIN RESIN TUBE CONNECTING COUPLING WITH FLANGE INSERT, discloses a coupling provided with a body having opposed front and rear ends. A large diameter chamber extends into the rear end and a communication hole extends into the front end. A small diameter chamber connects the communication hole and the large diameter chamber. A split annular grip with an inwardly directed annular pawl is disposed in the small diameter chamber and is dimensioned for surrounding the tube. All of the components inserted in the staged bore are extracted therefrom, with the tube. In other words, the banding ring is not extracted by itself, as it is in the present invention. The banding ring cannot move with respect to the latch, with or without a tube. In the present invention, however, the banding ring may or may not pass the latch, depending on the radial position thereof.
The present invention seeks to provide a quick coupling device of the above-specified type which is simple and compact in structure and which is extremely simple to implement, in particular on the occasion of initial coupling.
To achieve this end, the invention provides a quick coupling device for coupling a tube to a rigid endpiece including a female part secured to the rigid endpiece and in which a staged bore is provided that presents a section of large diameter beyond an axial latch that is movable between two positions, the device comprising a banding ring housed in removable manner in the large diameter section and fitted on its inside surface with at least one retaining projection forming axial connection means between the tube and the banding ring by biting into the outside surface of the tube, the axial latch in one of its two positions opposing axial displacement of the banding ring away from the rigid endpiece and, in its other position, releasing the banding ring.
Thus, the device is in the form of a part that is compact, the banding ring being integrated in the female part. On initial coupling, when the tube is inserted into the female part, the retaining projection of the banding ring fixes the ring permanently on the tube. This insertion can be performed by hand insofar as clamping of the banding ring on the tube does not serve to provide sealing, with sealing being provided directly between the female part and the tube. The axial latch prevents the tube from being disconnected by opposing axial displacement of the banding ring away from the rigid endpiece. To disconnect the tube fitted with its banding ring, it suffices to release the axial latch to allow the banding ring to pass and disconnect the tube which remains fitted with its banding ring. If it is desired to recouple the tube to the endpiece, it then suffices to slide the tube fitted with its ring inside the female part until the ring has gone past the axial latch. After the latch has been engaged, the tube is again prevented from moving axially inside the female part.
The banding ring may have a conical bore that converges towards the rigid endpiece and that has a small diameter that is smaller than the outside diameter of the tube, or it may have a cylindrical bore that is fitted with at least one retaining tooth.

How to Adjust the Height of an Office Chair
There are many different styles of office chairs available both online and in retail stores, however most modern or new models are designed to be adjusted pneumatically. Chairs that feature a pneumatic height adjustment can simply be adjusted by pushing or pulling either a button or lever located right below the seat. With a little bit of pressure exerted by you while pushing or pulling the button or lever below the seat, you may easily have the chair's height go down. If you get off your chair and pull or push that same button or lever you can just as easily have the chair's height go up. Older office chair models can be adjusted by turning a thick bolt which allows you to pick the height you would like to have your chair positioned at. Adjusting the height of your chair may seem like common sense and a trivial matter, but it is actually very important to adjust the height to fit your body type. Chairs that are not properly adjusted to meet the needs of the user may cause back pain, eye strain from not being properly positioned in front of your computer screen, fatigue from poor circulation, and numerous other health issues. This can be especially true if you sit in the same position for long periods of time.
When determining the correct height to have your office chair at, first make sure to place it in front of the desk or work area you will be spending most of your time at. If you have a keyboard tray installed underneath your desk, you will also need to take that into consideration when deciding the correct height your office chair should be at. Keep in mind that you will want to have a good amount of clearance between your keyboard tray or desk and your thighs to enable you to work more comfortably. If your computer chair comes with arms you will also want to take that into consideration as well especially if they are not height adjustable.
Once you have determined where you will be spending most of your time sitting and ergonomic accessories that may also play a part in the height adjustment of your chair, you will want to locate where the button or lever is on your chair that controls the height. On most chair models, it is generally located on the right hand side of the chair right below the seat. Some higher end chairs may even have pictures on their levers explaining what each lever on the chair does. All chair models will vary, and you will need to take the time to understand what each button does in order to fully adjust your chair to meet your needs.
After you fully understand how to adjust your chair, place the chair in front of the work area in which you will be using it most often. If your chair can be adjusted pneumatically simply apply a little pressure and push down on the seat while pulling the lever up to have the chair go down in height. To have the chair go up, apply a little pressure to the bottom of the seat and pull up with one hand while simultaneously pulling the lever up with the other. Computer chairs that do not have a pneumatic lift can be adjusted by loosening the height adjustment bolt by hand and pulling up or pushing down on the seat until the desired height is reached. Once you are happy with the height of the chair you will then need to tighten the bolt back to its original place.
The most important part of this process is making sure to test the chair's height. Once you have reached the height you think your chair will work best for you at, take a seat to see how it feels. Your feet should be resting flat on the floor, with your knees bent at a ninety degree angle to optimize blood flow. It may take a few tries to get your chair positioned at the correct height, but keep in mind that it is important that you do to avoid unnecessary stress and pains. Some chairs will automatically lock into place once you have released the pneumatic height lever. Others may have a separate locking mechanism. If your chair requires a locking mechanism to lock the height in place, make sure to do so before putting your full weight on the chair.
With all office chairs, be sure to treat them with care. Raising and lowering your chair often may cause the chair to wear out quicker over time. If you do not share your chair with others, try to find your ideal height and keep it there, only adjusting it when necessary.

Advances in Maintenance For Yokohama Fenders
Pneumatic fenders are essential for preventing damage between ships, or between ships and wharves. Yokohama has been a leader in the field for so long that the term "Yokohama Fender" has become synonymous with pneumatic fenders in general. The company currently dominates the field with a full 80% of all the pneumatic fenders being manufactured today.
Though pneumatic fenders are sturdy and adaptable to many situations and circumstances, they are not indestructible and do require periodic maintenance. In the past, this typically involved lifting them completely out of the water for inspection and a check of their inflation pressure. Obviously, this cuts into the efficiency of an entire wharf or dock operation when pneumatic fenders are taken out of commission completely for maintenance.
Yokohama recently announced a system that can monitor air pressure by remote sensing (a system adapted from their Air Watch setup for automotive tires). Dubbed the Fender Watch system, it entails a sensor on a metal fitting, set inside a Yokohama fender. Via a wireless signal, the sensor sends inflation data to the handheld terminals of maintenance personnel. With this system, maintenance can get accurate readings on the fender's inflation at distances up to 30 meters. This remote pressure sensing can also help monitor and regulate the distance between two vessels during ship-to-ship transfers of crude oil or liquefied petroleum gas.
Since pneumatic fenders are typically used in batteries of four or more, Yokohama's Fender Watch system can take readings from up to four fenders simultaneously. The sensors are also equipped to send alarm signals should the inflation pressure move significantly above or below the desired settings set by the users.

Fitting Tyres Correctly and Quickly With Wheel Balancers
It is very important that tyres are balanced correctly. If wheels are not balanced it can cause vibration and make the vehicle uncomfortable to drive. This can also cause wear in the suspension, meaning more expensive visits to the garage. The first signs of incorrect balance is the steering wobbles on the car when driving at speed.
The best way to do this correctly is to use a wheel balancer machine. The machine rotates the tyre and wheel assembly and automatically calculates the weight and location of the balance counter weight. There are many types of machine out there suited for different purposes.
Smaller machines are suitable for smaller cars and motorcycles. These are controlled by hand spin and are suitable for bike shops for a low cost solution. There are slightly more advanced machines that rotate automatically at hand speed, so there is no need for a guard and is more compact for those with little space.
The more expensive and advanced machines are all automated. Pre-programmed weights can be selected so the wheel is automatically balanced perfectly. These are more suited to tyre shops. These wheel balancers can be even more advanced with colour VDU displays and printers to show results. Some of these have a weight placement arm for better control and testing.
Of course there are even bigger machines that are for heavy goods vehicles. Only specialised tyre fitters usually have these for commercial vehicles. They have pneumatic lifts for raising the shaft height, so it is not only easier but safer.

Smart Tips to Use Pneumatic Floor Stapler
When talking about wood-flooring, you will find that it uses a tongue-and-groove system to lay the flooring. The system will mill the wood-flooring into the sides of the boards. In order give a tight fit, a tongue will be set to fit the groove. In this matter, the use of pneumatic floor stapler is very important. This is a type of tool that is designed for the tongue-and-groove flooring installation. You will find that the mallet is used to trigger the shooting of the staple. This will drive the boards tightly get together when the staple is shot. When you are about to use this tool, you can follow the following steps.
1. You should lay the first board. In this matter, you have to make sure that the grooved side faces the wall. Also you have to make sure that you make 3/8-inch expansion gap from it. You will find that this expansion gap will allow the board to make movement when the climate changes. But next, you will find that this will be covered up by the floor trim. When you are sure about those things, you can nail down the first board with your nail gun by shooting pairs of nails to the face of the board.
2. You should lay the next boards. For this, you should connect the ends of the boards. You should cut the final pieces on your miter saw at the walls as you need. Then, you should continue the process for the next few courses. In this step, you should connect them by their tongue-and-groove sides. You should also do the top-nailing as the previous step. You have to do this until you have enough courses so that you can sit the pneumatic floor stapler. For this, you might need four or five courses.
3. The next thing that you should do is that you should hook the stapler that you will use up to the air tank. Alongside the previous boards that you have installed, you should set the board of the next course. Make sure that it is in its place correctly. On the top installed courses, you should sit the stapler. Make sure that its nose hook down over the new board that you will install.
4. Gently, knock the stapler against that floorboard. For this, you can use the mallet that you have. After that, you should swing it fully so that it hits the rubber firing pad of the stapler.
5. Then, you should do that in every foot on the board. Make sure that you staple the board perfectly. When you have finished with this process, you can use your miter saw for cutting the end of pieces of the board when it is needed.
6. Finally, you should it across the floor with the pneumatic stapler until you are close to the opposing wall or you find that there is no longer enough room to fully swing the mallet. Lay the last few courses with your nail gun, as you did the first few courses.

Pneumatics and Control Valves Part 2
Air compressors are often called a hidden utility because not many people know about air compressors. The closest they get to an air compressor is the buzzing of air wrenches when they get their tires fitted. There are a myriad of pneumatic tools available on the market today. Cabinet and furniture shops use pneumatic nail guns and staplers, because nothing else compares to the speed and reliability of these tools. Blow off guns are the most common use for compressed air. From blowing off chips in a machine shop to a makeshift air brooms, these guns are extremely convenient tools. A blow off gun is simply a push button valve with a discharge valve to focus the escaping air. This type of gun is preferred when operators are restricted to specific machines, such as lathes, mills and punch presses.
Pneumatic energy is regulated and controlled by pneumatic valves. Functionally, valves are divided into four major groups viz, direction control, flow control, pressure control and non-return and special type valves. As per construction, valves are sub-grouped as seat valves and sliding or spool valves. However, spool valves are easier to manufacture. Valves are actuated in various methods, viz, manually, mechanically, electrically, pneumatically and by various combined mode of actuation. Specially designed valves like quick exhaust, time delay and shuttle and twin pressure valves are used to impart various functions to pneumatic circuits.
To control the to and fro motion of a pneumatic cylinder, the air energy needs to be regulated, controlled and reversed with a pre determined sequence in a pneumatic system. Similarly, one may have to control the quantity of pressure and flow rate to generate the desired level of force and speed of actuators. To achieve these functions valves are used. Valves are fluid power elements used for controlling and regulating the working medium, i.e, the compressed air in the case of a pneumatic system.
Board valves are used to start and stop pneumatic energy, control the direction of flow of compressed air, control the flow rate of compressed air and control the pressure rating of the compressed air. Direction control valves are mainly used to direct the flow of pressure fluid in the desired direction. They can be actuated to assume different positions by various actuating mediums. This results in corresponding connection or disruption of flow between various port openings. Direction control valves have two, three, four or five ports or openings.
In a direction control valve, the force is applied directly on the working piston or spool. The control method could be manual, mechanical, pneumatic, magnetic or a combination of any two. Magnets are commonly used for actuation of pneumatic valves. When the magnet is excited, the plunger gets attracted to it and it presses down on the valve spool. The pneumatic method acts on a spool or piston with a large area which in turn transfers the actuating force to the spool. Mechanical method involves the use of rollers, springs and other mechanical elements are used to actuate the valve. In the manual method the angular movement of a pedal or lever is transmitted to the spool.
Pneumatic energy is regulated and controlled by pneumatic valves. Functionally, valves are divided into four major groups viz, direction control, flow control, pressure control and non-return and special type valves. As per construction, valves are sub-grouped as seat valves and sliding or spool valves. However, spool valves are easier to manufacture. Valves are actuated in various methods, viz, manually, mechanically, electrically, pneumatically and by various combined mode of actuation. Specially designed valves like quick exhaust, time delay and shuttle and twin pressure valves are used to impart various functions to pneumatic circuits.
To control the to and fro motion of a pneumatic cylinder, the air energy needs to be regulated, controlled and reversed with a pre determined sequence in a pneumatic system. Similarly, one may have to control the quantity of pressure and flow rate to generate the desired level of force and speed of actuators. To achieve these functions valves are used. Valves are fluid power elements used for controlling and regulating the working medium, i.e, the compressed air in the case of a pneumatic system.
