What Are the Different Sewing Machine Parts?

There are several different types of sewing machine supplies. Basic sewing machine supplies include needles, bobbins, and thread. sewing machine presser foot may also come in handy for various projects or fabrics. Mats that keep a sewing machine pedal from sliding can also be found. To hold all of their sewing machine supplies, some people may opt to purchase a sewing cabinet.
Bobbins are also considered to be basic sewing machine supplies. These tiny metal spools are used to hold the bottom thread in a sewing machine. Most sewing machine users also have several bobbins as well, each filled with a different colored thread.
Thread is another type of sewing machine supply. Thread can be found in craft stores and fabric shops in just about any color imaginable. Some thread is even metallic. These sewing machine supplies also come in different thicknesses and weights.
A sewing machine presser foot is the part of the sewing machine that helps clamp the fabric to the bottom part of the machine. These can often be removed and changed rather easily. A regular presser foot will usually work for most sewing jobs, but there are also other types of special presser feet. Rolling or walking presser feet, for instance, are usually used with fabrics that might stick to a regular presser foot. http://www.yihshin.com/e-index1.htm

China solar inverter
China solar inverter

china solar inverter, or PV inverter, converts the variable direct current output of a photovoltaic (PV) solar panel into a utility frequency alternating current that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical component in a photovoltaic system, allowing the use of ordinary commercial appliances. China solar inverter has special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.


Grid tied china solar inverter
A PV inverter installed in a porchSolar grid-tie inverters are designed to quickly disconnect from the grid if the utility grid goes down. This is an NEC requirement that ensures that in the event of a blackout, the grid tie inverter will shut down to prevent the energy it produces from harming any line workers who are sent to fix the power grid.

Grid-tie inverters that are available on the market today use a number of different technologies. The china solar inverter may use the newer high-frequency transformers, conventional low-frequency transformers, or no transformer. Instead of converting direct current directly to 120 or 240 volts AC, high-frequency transformers employ a computerized multi-step process that involves converting the power to high-frequency AC and then back to DC and then to the final AC output voltage.

While there have historically concerns about having transformerless electrical systems feed into the public utility grid since the lack of galvanic isolation between the DC and AC circuits could allow the passage of dangerous DC faults to be transmitted to the AC side[15]; Since 2005, the NFPA s NEC allow transformerless (or non-galvanically) inverters. The VDE 0126-1-1 and IEC 6210 also have been amended to allow and define the safety mechanisms needed for such systems. Primarily, residual or ground current detection is used to detect possible fault conditions. Also isolation tests are performed to insure DC to AC separation.

Many solar inverters are designed to be connected to a utility grid, and will not operate when they do not detect the presence of the grid. They contain special circuitry to precisely match the voltage and frequency of the grid. See the Anti-Islanding section for more details. http://www.gdgee.com/95-pv-micro-grid-inverters-202/

A table cloth is a cloth used to cover a table
A table cloth is a cloth used to cover a table. Some are mainly ornamental coverings, which may also help protect the table from scratches and stains. Other table cloths are designed to be spread on a dining table before laying out tableware and food.

Ornamental table cloths can be made of almost any material, including delicate fabrics like embroidered silk. Dining cloths are typically made of cotton, a poly-cotton blend, or a PVC-coated material that can be wiped clean, but they can range from functional coverings to fine textiles, as long as they can be laundered. Some cloths are designed as part of an overall table setting, with coordinating napkins, placemats, or other decorative pieces. Special kinds of table cloth include runners which overhang the table at two ends only, and table protectors to provide a padded layer under a normal cloth.

In many European cultures a white, or mainly white, Table cloth used to be the standard covering for a dinner table. In the later medieval period spreading a high quality white linen or cotton cloth was an important part of preparing for a feast in a wealthy household. Over time the custom of arranging tableware on a cloth became common for most social classes except the very poorest. As eating habits changed in the 20th century, a much greater range of table-setting styles developed. Some formal dinners still use white table cloths, often with a damask weave, but other colours and patterns are possible.

Perugia table cloths and napkins have been made since medieval times. White with characteristic woven blue stripes and patterns, the style is also associated with church linen.

Victorian interiors were full of thick, fringed draperies in deep colours, including table cloths reaching to the floor on any kind of table.

A popular "magic trick" involved pulling a loaded table cloth away from a table but leaving the plates behind. This trick relies on inertia.http://www.xinxingplastic.com/

tablecloth fabrication
A tablecloth should have a 6" - 10" drop. To select the right cloth, add approximately 12 to 20 inches to the actual length and width of your table. Banquet-sized tables, which are extra-wide, will use an oversized cloth that is 70" in width.

Still, the drop length is somewhat of a personal preference, so add inches for a drop that will suit your needs and style. When in doubt, err on the larger size; it is better that your tablecloth is too long than too short.

Here s a little equation:
TABLE LENGTH + (DROP X 2) = THE TABLECLOTH LENGTH YOU LL NEED

So for example, if your table is 60", you would calculate the cloth as follows:
60" TABLE + 12" DROP X 2 (24") = 84" TABLECLOTH. THIS WILL BE PERFECT

fabrication

Below are the most common fabric types. As always, check packaging for cleaning and care specifics:

MICROFIBER: Microfiber is spill and stain-resistant. It is easy to care for and no ironing is required.

POLYESTER: Polyester is machine washable, so it is easy to care for with relatively no ironing required.

COTTON BLEND: Usually blended with polyester, cotton blend cloths require minimal touch-ups with an iron.

COTTON: Cotton cloths are machine washable and only require ironing when necessary.

LAMINATED FABRIC: Perfect for wiping clean after dinner, laminated cloths are easy to clean; however, you can not iron a laminated fabric.

VINYL: For use both indoors and outdoors, vinyl fabrics wipe clean easily. Like laminated fabrics, vinyl can not be ironed either.

For those tablecloths that you can not iron, lay out the tablecloth overnight. Lightly spray the cloth with water. Over time, gravity will work to pull the tablecloth smooth.

setting the table

In addition to a tablecloth, there are other items to consider when setting a beautiful table.

NAPKINS: As a great decorative accent, napkins can be mixed and matched to coordinate with the tablecloth and your dinnerware. They are not only necessary for making your guests feel comfortable, they can also be folded into creative shapes to make for an ultimate dining aesthetic. Remember, too, that some extra napkins are essential for use in bread baskets or in case of staining.

NAPKIN RINGS: Ranging from simple gold and silver to more ornate beaded or floral clusters, napkin rings are the finishing touch to any table.

RUNNERS: Runners can be placed on tables in multiples or just as a single. They can also be placed over a tablecloth as a vertical or horizontal design accent. Perfect for any size or shape of table, runners serve to enhance the look of a simple tablecloth by adding style that s all your own.

TABLE PADS: A table pad helps keep tablecloths in place while protecting the table from moderate heat, stains, or potential scratches. Table pads have a vinyl surface with a felt back in order to stay securely on the table. Offered in multiple sizes, they can be cut to fit any table perfectly.

TABLECLOTH PROTECTORS: If you want the look of a cotton tablecloth, but want clean-up to be a breeze, clear protectors are a great solution. They keep your tablecloth looking new, while offering you the option to wipe-clean after dinner.

PLACEMATS: Available in an array of patterns and fabrics, placemats can be used alone or with a tablecloth. Feel free to mix and match styles and fabrics for an eclectic look.http://www.xinxingplastic.com/

Simple Sewing for Kids: T-shirt Bag
Now that we’ve done a little practicing by making a fabric bookmark, my son is ready for our next project: Sewing a T-shirt Bag. This is probably the easiest project out there. All you do is sew one long line. That’s it! And it makes such a fun and functional piece. The best part is you don’t have to sew a perfect line. Your bag is going to look great even if your stitched line is a little off, perfect for a beginner.


We found an old t-shirt we had that didn’t fit so well to practice on for our first time. But these would actually be really fun and cute to make with special t-shirts the kids have outgrown, recycling them into something new. Or you could even buy a few t-shirts for this purpose, to get the right color or wording for your bag. These bags are great for the beach or the park… summer here we come!!

Here’s how we made our t-shirt bag!

Supplies for T-shirt Bag sewing project:
cotton t-shirt, any size works. This just depends on the size of bag you’d like.
(don’t mind the wrinkles :)
scissors
sewing machine or needle and thread


1. Start by cutting off the sleeves of the shirt. We cut right inside the seam of the arms. You’ll also want to cut off the neck line of the shirt. This makes for a larger space to hold the bag on your shoulder and to open it up and put things inside. So how much you cut it is up to you.


You can also fold your shirt in half and cut it this way to make sure your sides are even. Either way!


2. Turn your shirt inside out and match up the bottom edges of the t-shirt together. You can pin this or just watch the edges and make sure they are together as you sew. Sew these together, starting and ending with a back stitch to help the thread stay put. You simply sew a straight line.


3. Turn your shirt back out, with the front side out, and you’re done. It’s that simple!



Now your new T-shirt bag is ready for groceries or toys, handmade by YOU! But beware: these are addicting. We now have a whole set of t-shirt bags to take everywhere!http://www.xinxingplastic.com/

The Only Solar Inverter Site You ll Ever Need

What Is a PV solar Inverter?
PV solar Inverter are some of the most important gadgets that most homeowners have been using today. In the simplest terms, they are devices that serve to convert direct current (AC) to alternate current (AC) using solar power. Before going into the value of solar inverters, however, we need to understand the differences between AC and DC power and how a DC to AC conversion helps.

DC power is power that runs in one direction in an electrical circuit and is made possible when there is a power source. For example, your cellphone runs on DC power that is supplied from your cellphone battery (where power is stored) to the specific electronic components that make the device function as it should. The power is supplied to these components in one direction until the battery is depleted and has to be recharged. DC power is required for sensitive gadgets where a steady amount of electricity has to be maintained. If, for instance, you have a CD player that requires 220 volts, you have to use a 220-volt battery for it. If you use a battery that gives less than this, your device will not function completely. If your battery exceeds the requirement, this could result in a burnout and you could end up damaging the CD player. You can use a resistor, but this will mean a waste of voltage.

The role of the PV solar Inverter then is to allow DC-powered devices to run on AC power for the user to enjoy AC’s advantages. The question is, why a solar inverter? There are many advantages to using solar energy. Remember that solar energy is a naturally renewable resource, and even if solar-powered devices may not be very cheap at the moment, long-term savings can still be made because its source is free for all. On top of this, we all know that solar energy is environment-friendly. Obtaining, storing and using it will not result in toxic CO2 emissions which are known hazards to the ozone layer.

A solar inverter can be a better choice for converting DC power to AC power for your home appliances. Also called photovoltaic or PV solar inverter, these devices can help you save mother earth and make long-term savings on your budget. http://www.gdgee.com/95-pv-micro-grid-inverters-202/

Galvanic Corrosion Through a Spiral Wound Gasket
Galvanic Corrosion Through a Spiral Wound Gasket

The elbow pictured to the left was removed from a pump volute. The pump was a cantilevered pump in submerged service and it had been in service for six years. During that period of time it had been removed for various reasons. However, this time there appeared to be a great degree of metal missing in the gasket region. The gasket specification recommended by the OEM was a fiber gasket, but the service it was used in called for a spiral wound gasket shown in Figure 2. The gasket that came out of service was never recovered and therefore a critical piece of evidence was lost. However, the corrosion pattern was pretty obvious and a new gasket was positioned exactly as the corrosion pattern indicated. The position of the old gasket is shown in Figure 2 with the new gasket. When looking at the corrosion pattern in Figure 3 and then looking at the offset position of the gasket in Figure 2 one might be quick to think that turbulence eroded the region of greatest metal loss.

However, when a ruler was placed over the flange face (Figure 4, left) it revealed that the flange face nearest the inner diameter of the pipe elbow was still there. Only the metal directly underneath the spiral wound portion of the gasket was missing. Erosion was ruled out.

The next possibility was crevice corrosion. Crevice corrosion requires very tight clearances where stagnant conditions can exist. It is not uncommon for some gaskets to wick and allow favorable conditions for crevice corrosion to initiate. When looking at Figure 5 there were deposits that accumulated between the retaining ring and the chrome-steel flange face. The imprint of the retaining ring remained on the deposits. There were clear signs of green oxides where chromium reacted. When the deposits were removed, as shown in Figure 6, the flange face was still in good condition. Crevice corrosion is not preferential in where it attacks, yet there was a clear demarcation line between the attacked region (under the spiral windings) and the retaining ring that did not come into contact with the flange (as evidenced by the accumulation of deposits shown in both figures).

If the cause for the metal removal on the flange face wasn t erosion or crevice corrosion, then what was it? It was certain that there was evidence of a corrosion mechanism. There were definite signs of corrosion byproducts in Figure 3. The green regions were chromium oxides. A close up view of the lower right region in Figure 3 can be seen by clicking on it. The elbow was a 29% chromium-iron material. The gasket was a 316 stainless steel spiral wound gasket with a 316 stainless steel retaining ring. If it were galvanic corrosion then a clear circuit path would have to exist between the flange face and the gasket. http://www.sealmaterial.com.cn/
