God's Perfection...
kiss the clouds
that we may look up beyond
our own small world
and strive to reach great heights.
He made the ocean wide and mighty
to remind us of the
greatness of his love
and the power of his strength.
He frosts the earth with
diamonds in the winter
to reveal the riches that
await us in heaven,
and he awakens the earth
with a profusion of lilacs and daffodils
in the spring to show us that
we've been given
the gift of eternal life.
He has created masterpieces,
and every one of them
are part of the circle of life and serve
some great purpose.
From the forests, to the valleys,
across the dales, and even to the
most distant twinkling star,
and the early morning mist that
creeps over the hills,
God has blessed the earth with
his talented hand.
So do you think that God could have
erred when he made you?
Of course he didn't.
You're perfect,
exactly what God intended you to be.
As the earth is reborn this spring,
remember that you're one of
God's great masterpieces,
a testament to his infinite
wisdom and perfection.
INDUCTION WELDING
Induction welding is a form of welding that uses electromagnetic induction to heat the workpiece. The welding apparatus contains an induction coil that is energised with a radio-frequency electric current. This generates a high-frequency electromagnetic field that acts on either an electrically conductive or a ferromagnetic workpiece. In an electrically conductive workpiece, such as steel, the main heating effect is resistive heating, which is due to magnetically induced currents called eddy currents. In a ferromagnetic workpiece, such as plastic doped with ceramic particles, the heating is caused mainly by hysteresis as the magnetic component of the electromagnetic field repeatedly distorts the crystalline structure of the ferromagnetic material. In practice, most materials undergo a combination of these two effects.
As suggested above, nonmagnetic materials such as plastics can be induction-welded by implanting them with metallic or ferromagnetic compounds, called susceptors, that absorb the electromagnetic energy from the induction coil, become hot, and lose their heat energy to the surrounding material by thermal conduction.
Induction welding describes welding techniques where heating is generated by an induction field. The two most commonly encountered mechanisms by which heat can be generated by an induction field are eddy current heating and heating due to hysteresis losses.
Induction welding is similar to resistive implant welding, in that an electrically conducting implant is required at the joint line. A work coil, which is connected to a high frequency power supply, is then placed in close proximity to the joint. As electric current at high frequency passes through the work coil, a dynamic magnetic field is generated whose flux links the implant. For induction welding by eddy current generation, electric currents are induced in the implant and when these are sufficiently high to heat the conducting material, the surrounding thermoplastic parts melt or soften. If pressure is applied to the joint a weld will form.
Induction welding can be very fast; weld times may be a few seconds. Applications include sealing plastic coated metal caps to plastic bottles and welding metal grilles to the front of loudspeaker units. In both of these cases, the implant has been a part of the item being welded. One of the features governing the efficiency of induction welding is the magnetic permeability of the implant. If the implant has high relative permeability, i.e. is ferromagnetic, then heating may be very rapid.
Induction welding via eddy current generation has also found use in joining advanced thermoplastic composites. The fact that many carbon fibre reinforced composites conduct AC and DC electric current is probably due to percolation , although several other theories exist. It is therefore possible to heat many carbon fibre reinforced thermoplastic composites using an induction field to produce a weld, and several research groups have harnessed this effect.
Recently, a new form of induction welding by eddy current has been developed. Originally developed by Metcal and now owned by Uponor this new concept revolves around an implant material that is able to 'switch off' at certain temperatures. The implant is ferromagnetic (has high relative permeability) until it reaches a certain temperature (the Curie point) above which it becomes paramagnetic and loses its ferromagnetic properties. This results in a very large reduction in heating effect by induction. As the implant cools back through the Curie point, the implant becomes ferromagnetic once more and heating recommences. In this way it is possible to stabilise the weld temperature around the implant. It is also possible to alter the characteristic Curie point by varying
the composition of the alloy comprising the implant. Field trials on polyethylene pipes have demonstrated that this system enables the temperature in the joint to be controlled and hence the chance that welds are defective due to overheating is dramatically reduced.
Induction welding by eddy current heating is generally a geometry dependent technique because complete circuits are required to allow eddy currents to flow in the implant. For this reason, long thin linear joints are difficult to induction weld using eddy current generation. Where components contain circular symmetry or complete circuital implant paths this technique is often the most efficient. If the thermoplastic component to be joined is electrically conductive, due to filler content for example, the development of induction welding may be difficult due to problems with controlling the distribution of eddy currents.
As suggested above, nonmagnetic materials such as plastics can be induction-welded by implanting them with metallic or ferromagnetic compounds, called susceptors, that absorb the electromagnetic energy from the induction coil, become hot, and lose their heat energy to the surrounding material by thermal conduction.
World of ur smile
Is it something as simple as the gift of flowers,
Or maybe the enthusiastic greeting of a loved pet,
An ambrace from someone you love?
I`d celebrate with you in your triumphs,
Comfort you in sorrow,
Be a companion in trying times.
If it were in my power
I`d give you the world for your smile.
What does it takes to make you smile?
Something so subtle as the happiness of others,
The soft soughing wind on a hot summer`s day,
Or could I smile at you to prompt one in return?
I`d tell you a thousand times how I care for you,
Listen to you speak if only to hear your voice,
Support you in any endeavor.
I`d give you my shoulder to lean upon when you grow weary,
Hold you until we both drift asleep
I`d give you my world for your smile.
To see the gladness of your heart reflected in your smile
Brings such warmth and happiness to me
To have the chance to share it with you
My world is yours only for the asking.
Feelin ur Love!!!!!!!~~~~~~~~Gud1~~~~~~~~~
Each day brings so much promise.
Every dawn arrives with a breath of pure love.
Having your hand to hold in mine,
sharing our deepest thoughts.
Memories of your sweetest kisses
carry me through the times we are apart.
Can you remember our very first hug?
Tears of joy and happiness blending into one.
Remember the first kiss?
Seemed so fleeting, yet,
it continues to this day, never to end.
Our first night brought such nervous laughter.
Curious hugs. Passionate embraces.
Love finding love. Lovers becoming lost.
Early morning coffee, sweetened with your kisses.
The morning paper being only something to peek over and around.
Winks and smiles crossing each other's path,
on their way to the intended, as we pretended to be reading.
This love has indeed traveled such a wonderful journey.
We have seen so very much together.
Love allowing each other to see so much more than ever before.
Never forgetting just how much you mean to me.
Knowing you are so wonderful.
So happy you decided to take that chance.
So happy to be in love with you.
So happy to be feeling your love.
How Smart U r
Below are four (4) questions and a bonus question. You have to answer them
instantly. You can't take your time, answer all of them immediately. OK?
Let's find out just how clever you really are.
Ready?
GO!!! (Scroll down)
First Question:
You are participating in a race. You overtake the second person. What
position are you in?
Answer: If you answered that you are first, then you are absolutely wrong!
If you overtake the second person and you take his place, you are second!
Try not to screw up in the next question.
To answer the second question, don't take as much time as you took for the
first question.
Second Question: If you overtake the last person, then you are...?
Answer: If you answered that you are second to last, then you are wrong
again. Tell me, how can you overtake the LAST person?!
You're not very good at this! Are you?
Third Question: Very tricky math! Note: This must be done in your head only.
Do NOT use paper and pencil or a calculator. Try it.
Take 1000 and add 40 to it. Now add another 1000. Now add 30. Add another
1000. Now add 20. Now add another 1000. Now add 10. What is the total?
Scroll down for answer...
Did you get 5000? The correct answer is actually 4100.
Don't believe it? Check with your calculator! Today is definitely not your
day. Maybe you will get the last question right?
Mary's father has five daughters: 1. Nana, 2. Nene, 3. Nini, 4. Nono. What
is the name of the fifth daughter?
Answer: Nunu?
NO! Of course not. Her name is Mary. Read the question again
Okay, now the bonus round . . .
There is a mute person who wants to buy a toothbrush. By imitating the
action of brushing one's teeth he successfully expresses himself to the
shopkeeper and the purchase is done.
Now if there is a blind man who wishes to buy a pair of sunglasses, how
should he express himself?
