Shea Butter

Shea butter, also known as karite butter, is a cream-colored fatty substance made from the nuts of karite nut trees (also called Mangifolia trees) that grow in the savannah regions of West and Central Africa. Karite trees, or shea trees, are not cultivated. They grow only in the wild, and can take up to 50 years to mature (they live up to 300 years!). In most parts of West Africa, destruction of the shea tree is prohibited because this little nut provides a valuable source of food, medicine, and income for the population. In fact, shea butter is sometimes referred to as gold?in Africa, because so many women are employed in the production of shea butter.

Why is shea butter in such demand? Western countries are just beginning to recognize the considerable health and beauty benefits of shea butter, something Africans have known for thousands of years. Shea butter has been used to help heal burns, sores, scars, dermatitis, psoriasis, dandruff, and stretch marks. It may also help diminish wrinkles by moisturizing the skin, promoting cell renewal, and increasing circulation. Shea butter also contains cinnamic acid, a substance that helps protect the skin from harmful UV rays.

Shea butter is a particularly effective moisturizer because contains so many fatty acids, which are needed to retain skin moisture and elasticity. The high fatty acid content of shea butter also makes it an excellent additive to soap, shampoos, anti-aging creams, cosmetics, lotions, and massage oils梚ts soft, butter-like texture melts readily into the skin.

Shea butter protects the skin from both environmental and free-radical damage. It contains vitamins A and E, and has demonstrated both antimicrobial and anti-inflammatory properties.

Laser engraving machines

Laser engraving machines

A Laser engraving machine can be thought of as three main parts: a laser, a controller, and a surface. The laser is like a pencil - the beam emitted from it allows the controller to trace patterns onto the surface. The controller (usually a computer) controls the direction, intensity, speed of movement, and spread of the laser beam aimed at the surface. The surface is picked to match what the laser can act on.

There are three main genres of engraving machines: The most common is the X-Y table where, usually, the workpiece (surface) is stationary and the laser optics move around in X and Y directions, directing the laser beam to draw vectors. Sometimes the laser is stationary and the workpiece moves. Sometimes the workpiece moves in the Y axis and the laser in the X axis. A second genre is for cylindrical workpieces (or flat workpieces mounted around a cylinder) where the laser effectively traverses a fine helix and on/off laser pulsing produces the desired image on a raster basis. In the third method, both the laser and workpiece are stationary and galvo mirrors move the laser beam over the workpiece surface. Laser engravers using this technology can work in either raster or vector mode.

"X-Y" laser engraving machines may operate in vector and raster mode.

For surfaces that vary in height, more elaborate focusing mechanisms have been developed. Some are known as dynamic auto focus systems. They adjust the lasing parameters in real time to adapt to the changes to the material as it is being etched. Typically, the height and depth of the surface is monitored with devices tracking changes to ultrasound, infrared, or visible light aimed at the engraving surface. These devices, known as pilot beams or pilot lasers (if a laser is used) help guide the adjustments made to the lens of the laser in determining the optimal spot to focus on the surface and remove material effectively.

Wholesale Pet Supplies

Wholesale Pet Supplies

Wholesale pet supplies aren t just reserved for retailers. Consumers can also

benefit from deep discounts offered by wholesale distributors. Many companies have

online stores. Although some have a minimum order requirement and a few only sell

to dealers, retailers, and veterinary offices, most Wholesale pet suppliers sell

directly to consumers.

You can buy any type of pet item, including many vaccines, at wholesale prices.

Some wholesale companies specialize in certain items, such as grooming supplies or

veterinary supplies, and some specialize in supplies for certain kinds of animals,

such as horses, farm animals or pets.

Features

Wholesale pet supplies, especially toys, may be packaged in larger quantities and

sold at a bulk rate. The cost per toy is much lower than the retail price, but

shoppers must buy the whole package. However, many companies also sell individual

items at a low discount. Wholesale pet supply companies sell to retailers or to

dealers who then distribute to retailers. Some require an individual or store to

spend a minimum dollar amount. Even with this requirement, however, consumers can

save money from buying pet toys, clothing, accessories and other non-perishable

items in bulk.

Competition is great among wholesalers. This means you ll save money if you shop around to compare prices before making your purchase. Shipping costs can add up, but many companies offer free shipping for purchases above a certain dollar amount. Buying some pet supplies wholesale can save you a lot of money and time. Watch for sales. Like retail stores, wholesale pet supply companies often discount items to get rid of extra inventory.

Electric motor

Electric motor

An electric motor is an electromechanical device that converts electrical energy into mechanical energy.

Most electric motors operate through the interaction of magnetic fields and current-carrying conductors to generate force. The reverse process, producing electrical energy from mechanical energy, is done by generators such as an alternator or a dynamo; some electric motors can also be used as generators, for example, a dc electric motor on a vehicle may perform both tasks. Electric motors and generators are commonly referred to as electric machines.

dc electric motor are found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives. They may be powered by direct current, e.g., a battery powered portable device or motor vehicle, or by alternating current from a central electrical distribution grid or inverter. The smallest motors may be found in electric wristwatches. Medium-size motors of highly standardized dimensions and characteristics provide convenient mechanical power for industrial uses. The very largest electric motors are used for propulsion of ships, pipeline compressors, and water pumps with ratings in the millions of watts. Electric motors may be classified by the source of electric power, by their internal construction, by their application, or by the type of motion they give.

The physical principle behind production of mechanical force by the interactions of an electric current and a magnetic field, Faraday s law of induction, was discovered by Michael Faraday in 1831. Electric motors of increasing efficiency were constructed from 1821 through the end of the 19th century, but commercial exploitation of electric motors on a large scale required efficient electrical generators and electrical distribution networks. The first commercially successful motors were made around 1873

Brushless DC motor

Brushless DC motor

Brushless DC motors were developed from conventional brushed DC motors with the availability of solid state power semiconductors. So, why do we discuss brushless dc motor in a chapter on AC motors? Brushless DC motors are similar to AC synchronous motors. The major difference is that synchronous motors develop a sinusoidal back EMF, as compared to a rectangular, or trapezoidal, back EMF for brushless DC motors. Both have stator created rotating magnetic fields producing torque in a magnetic rotor.

Synchronous motors are usually large multi-kilowatt size, often with electromagnet rotors. True synchronous motors are considered to be single speed, a submultiple of the powerline frequency. Brushless DC motor tend to be small– a few watts to tens of watts, with permanent magnet rotors. The speed of a brushless DC motor is not fixed unless driven by a phased locked loop slaved to a reference frequency. The style of construction is either cylindrical or pancake.

The most usual construction, cylindrical, can take on two forms (Figure above). The most common cylindrical style is with the rotor on the inside, above right. This style motor is used in hard disk drives. It is also possible to put the rotor on the outside surrounding the stator. Such is the case with brushless DC fan motors, sans the shaft. This style of construction may be short and fat. However, the direction of the magnetic flux is radial with respect to the rotational axis.

How to Change the Bit on an Electric Screwdriver

How to Change the Bit on an Electric Screwdriver

Electric screwdrivers decrease the amount of work involved when driving multiple screws for a home improvement project. Most electric screwdriver are cordless and use rechargeable batteries to power the tool. They use interchangeable bits so that you can choose the bit that s appropriate for the type of screw you need to loosen or tighten. Many manufacturers make cordless electric screwdriver; changing the bit is similar for each brand of screwdriver. Does this Spark an idea?

1

Push the directional switch on the screwdriver to the center, using your finger. The directional switch is usually located toward the front of the trigger.

2

Remove the battery from the electric screwdriver to avoid accidentally turning on the tool while changing the bit. Some brands have two tabs on the side of the battery that you press in to pull the battery out; with other brands, the battery slides off the rear of the tool.

Use only the bits that come with your electric screwdriver. Screwdriver bits from different manufacturers are different lengths, and may not work properly when used with a different screwdriver brand.
