Answer: A picot stitch is made with chain stitches. For a small picot, chain 3, then put a slip stitch in the first chain stitch. For a larger picot, do 5 stitches the same way. If you chose to change the amount of stitches, odd numbers are best so that there is a middle stitch.
Answer: You should have an instruction booklet with your machine. That will show you where everything is. This will vary from machine to machine with some being simple and others you should be a rocket scientist to use.
The stitch width selector is pretty self explanatory. You use it to select the width of the stitch you want to use in a zig zag stitch.
Answer: Might be a kidney stone. I had them twice and the pain gets serious.A doctor said to me "if you feel it coming onto try to run up and down stairs to get the kidney stone to move. In both cases I was hospitalised but it came out in my urine, never had them blasted. I have put in a water filter / softener in my house since. Watch for bottled water - some brands are very high in calcium - which causes the problem.
Answer: A zigzag transformer is used in connection with 3 phase and is made up of 6 coils connected in a "Y" manner. Each leg of the "Y" is made up of a coil on a different phase leg of the transformer. The neutral formed by the zigzag connection is very stable. Therefore, this type of transformer, or in some cases an auto transformer, lends itself very well for establishing a neutral for an ungrounded 3 phase system. Many times this type of transformer or auto transformer, lends itself very well for establishing a neutral for an ungrounded 3 phase system. Many times this type of transformer or auto transformer will carry a fairly large rating, yet physically be relatively small. This particularly applies in connection with grounding applications. The reason for this small size in relation to the nameplate KVA rating is due to the fact that many types of grounding auto transformers are rated for 2 seconds. This is based on the time to operate an overcurrent protection device such as a breaker. Zigzag transformers used to be employed to enable size reductions in drive motor systems due to the stable wave form they present. Other means are now more common, such as 6 phase star.
Answer: The temperature difference of minus 70 degrees F and 145 degree oil filled pipe meant that a section of pipe would expand in length by 18 inches. When the temperature changes the pipe has to go somehere so the zigzag converts linear expansion into a sideways movement. Extreme zigzags were added where it crosses the Denali fault area to compensate for earthquake movement. The zigzag added 11 miles of pipeline to the project.
Answer: stop whatever exercise you are doing.. do not run through it.control your breathing slow it right down.. and stretch if you pull your arm up over your head.. and lean over away from the side of the stitch and start breathing more deeply while stretching this should ease it.
