Frictionless Compressor Technology Compressors that run on frictionless bearings are an enticing prospect. Here the the compressors operate without metal-to-metal contact by levitating the compressor shaft in a magnetic field. Thus the need for an oil management system is eliminated. Such type of compressors are designed to take advantage of the magnetic bearing technology. Magnetic bearings: The lubricated bearings in ordinary systems is replaced by a digitally controlled magnetic bearing system

Magnetic materials refer primarily to the materials with direct or indirect magnetism composed of transition elements like ferrum‚ cobalt‚ nickel and their alloys. Magnetic materials find application in wind power‚ electronics‚ computer‚ communication‚ medical treatment‚ household appliances and military fields. By quality and structure‚ magnetic materials can be classified into ferrite magnetic materials‚ rare earth magnetic materials‚ and others. In 2012‚ the number of flexible ferrite magnet

Procedure: 1. The compass was placed on the lab table with no magnets nearby to identify what direction was north relative to the classroom. 2. On the ends of the variable gap magnet there were two small magnetic disks. One arm of the magnet was unscrewed and removed from its housing. A meter stick was placed on the and the arm was on its side parallel to the meter stick. The Gauss-Tesla meter was used to measure the field strength of the magnet. The probe attached to the meter was perpendicular

I love seeing children have "light bulb" moments. It’s moments like those that let you know you have chosen the correct profession. I also chose teaching as my profession because when I was in elementary school I did not have good teachers to look up at. I struggled a lot in elementary school and my teachers just saw me as the problem child they did not have time to help. They made me feel horrible because I didn’t know the answer to a question they asked‚ or I needed help with something they thought

Let’s face it – we’ve all had our share of embarrassing moments. Just be thankful that none of them were as humiliating (and hilarious!) as these: "A mother was taking a shower when her2 year old son came into the bathroom and wrapped himself in toilet paper. Although he made a mess‚ he looked adorable‚ so she ran for my camera and took a few shots. They came out so well that she had copies made and included one with each of their Christmas cards. Days later‚ a relative called about the picture

Estee Zeldin My Most Compelling Moment As a young teen I always dreamt of accomplishing something that would have people’s eyes opened. Many doors were opened right before me and I could’ve walked through anyone. Having that opportunity I took the advantage I had and tried several doors. Doing so‚ after a while I never had the intentions of finishing what I began because nothing came naturally to me. At that point of my life I was 13 years old. The typical age of a girl who wants to be noticed

Now this might not seem like something that would make her uneasy‚ but trust me‚ it does. The girl expected me to be super nervous‚ so seeing me smile so confidently and at ease probably made her a little nervous. That little moment of nervousness is all I needed. The ref blew the whistle to signal that it was okay for her to shoot. I got set‚ and everything seemed to go in slow motion from that point on. My eyes were trained on the ball as she slowly jogged up to it‚ cocked
