Stepper Motors for Beverage Dispensing Equipment
A stepper motor is an electric motor that rotates through many small steps. The shaft is pulled around each step electromagnetically by a step controller. This type of motor uses the controller to convert electricity into mechanical energy by sending electrical pulses to energize permanent magnets in the motor causing the rotor to move one "step" for each pulse. Precision stepper motors control a variety of piston pumps in programmable beverage dispensing systems in both fixed and adjustable displacement configurations. These systems can be configured to control either one or two pump heads; with two pump heads, each pump can be controlled independently for dual proportional dispensing or synchronized to produce a smooth flow. NMB’s customizable stepper motors for beverage dispensing equipment include hybrid, permanent magnet, hybrid linear and hybrid gear boxes. These types of motors all offer integrated customizable electronics for ease of application development, systems reduction, and project proofing. While all stepper motors for beverage dispensing equipment can do similar jobs, there are differences in their performance. Permanent magnet and hybrid stepper motors are the two most commonly used stepper motors for beverage dispensing equipment.

The most common cloth napkins used are polyester and satin
Polyester table napkins, also known as wedding napkins, cloth napkins, or linen napkins are available in different sizes, materials, and colors. The most common cloth napkins used are polyester and satin, but polyester is more durable and longer lasting.
Sizing:
The size of wedding napkins is a personal preference, but there are other reasons different size napkins are available. For example, if you want decorate your tables by folding napkins into animal shapes or other styles, you do need bigger napkins. The most common sizes vary from 17 inch squares to 20 inch squares. The bigger the napkin the more styles you can fold them into and the easier it is to fold them. In addition to the sizing, the thickness or weight of the napkin needs to be right for them to be folded into designs and stand up. The weight of polyester material is determined by grams per square meters or GSM. 200 GSM is the ideal weight for polyester napkins if you are going to fold them into designs and stand them up without buckling.
Material:
Cloth napkins are available in polyester, satin, and poly-cotton materials. These are the most common linen napkins available in the market. The most durable and longest lasting are the plain polyester napkins. They can be washed and reused many times. Most sit down restaurants and banquet halls use polyester or poly-cotton napkins. Satin napkins are usually available to rent from event planners. Satin is a lighter, smoother, and shinier than polyester, but they don last through as many washes as do polyester napkins.
Tips:
1.If you have the choice of renting or buying your napkins it is recommended to buy them. Rented napkins are usually used, therefore might have stains on them. Since there are many wedding napkin wholesale websites selling napkins for rental prices you are better off buying brand new ones.
2.If you plan to fold your napkins into designs/decorations make sure you buy the right size and weight/thickness. Otherwise, the napkins might be too small and buckle once you set them on the table.
3.Although most common colors for napkins are white and ivory, consider using darker colors. If you plan to use the napkins for more than one occasion, permanent stains will not be noticeable on the darker colored napkins.

Sooner or later the rubber is going to go hard
Taps drip. It's inevitable, like death and taxes. They seal using a rubber ring screwed down over the end of a metal pipe. Sooner or later the rubber is going to go hard, split or just wear away and it will no longer seal. Then water seeps through, and the tap starts dripping. Left alone the problem gets worse as the water wears away the valve seat. Then you'll have to either re-grind the valve seat(Do you own a valve seat re-grinder? Who would?) or replace the tap. Tedious in either case. But, it need not happen. Many taps now use ceramic discs.
How They Work
Instead of blocking the pipe by squeezing a piece of rubber onto the end of it, there are two slotted ceramic discs held down over the water supply pipe. The bottom disc doesn't move, while the upper disc is rotated over it by the tap mechanism. When the slots align the the tap is on, and when the slots don't align, the tap is off.
Why Are They Better?
There are advantages to this approach. The main one is that the discs are very hard and withstand the erosion of water very well. Hence they last much longer before needing replacement. Also, because the water flow is between the two discs, it's the discs that wear not the tap body itself. Because of the arrangement of the discs, it only requires a quarter turn to go from fully off to fully on and the operation of the tap is very light. This has the advantage that they are easy to turn on with the back of the wrist if you have dirty hands or for people with restricted movement.
Where they are Used
The ease of operation and the long life mean that most good quality sink mixer taps have been made using ceramic discs for a while, but basin taps with ceramic discs are surprisingly less common. The more use a tap gets, the more attractive the use of ceramic disc technology becomes. This is doubly true in hard water areas, which can be murder on traditional taps.
Disadvantages
There are a few disadvantages. The discs do eventually wear out, but manufacturers seem to have standardised, so it is reasonably easy to get replacements. Basin taps are sometimes handed and sometimes not, and it can be annoying to have to work out which way to turn the tap in order to get water. They are also more expensive and not suitable for very low water pressure. The only other disadvantage is that if you are used to the old style taps, which need a number of turns to turn fully on, you may inadvertently turn the tap on more than you intended, you can get a unexpected full-on jet of water. Embarrassing!
