Getting inward relevant links for your home business that are one way is like the proverbial needle in the haystack.


Even when you do find other sites that are willing to exchange links there is no guarantee that your link will end up on a relevantly optimized page. Tried posting to free Directories and still waiting months down the track for your link to be published here is a way to get guaranteed relevant inward one way links.

Most web masters have realized that exchanging reciprocal links is not as effective as it used to be. Most of the major search engines give a lower rating for a reciprocal link than they do for a one-way link. So how do you go about getting quality inward links for your home based business site. We have all heard of the ABC format of exchanging links many Seo sites will tell you how this is done. What they don’t tell you is where to go to get these links.

If your Businesses site relies on Search engine traffic as opposed to other forms like pay per click or opt mail lists then getting inward one-way links is paramount to your Businesses success. Even if your Website pages have been finely honed to achieve the maximum benefits of Search engine optimization with out good quality relevant links you have very little hope of showing up on the first page of the results returned unless you have a low competition set of keywords in which case you’ll still want to have a linking campaign there are over one million new domains added to the Web everyday and without quality links its only a matter of time before competitors arrive and knock you off your perch.

So what are the options? There are many sites that cater to getting inward links for webmasters some require payment for their services other require you post a link back to them. The danger of doing this is you have no control where your link ends up or if the Search engines class the provider as a link farm.

Here is a way that is easy to set up that will guarantee all links you get are one way to your site and will encourage other webmasters to link back to you and all the relevant sites you link to. Create your own Business Directory on a Subdomain of your website. Subdomains are treated as individual websites by search engines so by you posting your link to other sites on your Directory and they posting their links to your main site in their site you both have achieved a one way link. Now by optimizing the pages in your Subdomain for linking categories e.g., Directory links, article links, your relevant business keywords etc and posting in links from all your sites and Blogs to your directory there is a benefit for other webmasters to exchange links with you as your pr and link rankings will flow through to these links.

Here is a quick tip for seeing future back links on Google (Google can take months to update backlinks) for sites you are considering exchanging links rather than typing in the search field link: the url , type site to url . If you have a site that is relevant to home business or home based opportunities don’t forget to post your link in our Directory.

Don't use a needle valve to control your air cylinder speed!

Many industrial machines using compressed air as an energy source, use air cylinders or other pneumatic actuators to do the actual work.

Compressed air is 'explosive' as it moves from high pressure to low pressure on it's way back to atmosphere. That means when the air valve shifts and air flows to the cylinder, the cylinder piston and rod moves extremely quickly. A high speed cylinder rod may not be best for your application, and you will want to reduce the speed and the impact.

One easy method of controlling the speed of an air cylinder is installing flow controls in the air lines between the valve to the air cylinder, in the cylinder ports themselves, or even in the exhaust ports of the air valve, though the latter is least desirable.

In the 'valve exhaust' type flow control the controls themselves may be far enough away from the cylinder that the piston and rod may have traveled the full stroke before the exhaust flow control can start back-pressuring the line to slow the cylinder. Cylinder control reaction time is always negatively affected depending on the distance from the cylinder to the flow control.

Some folks opt for needle valves to throttle the flow of air into and out of the air cylinder, thereby reducing it's speed. The problem with using a needle valve to control the speed of an air cylinder is that it throttles the compressed air flow equally in both directions.

If you are using a larger cylinder, by throttling the air into the cylinder, you are actually preventing the smooth cylinder stroke desired. As air pressure builds in the cylinder it will reach the point where it overcomes the friction of the piston and rod seals and the piston will start to move. As it moves, it increases the volume of the air space inside the cylinder behind itself. The piston moves toward one end of the cylinder creating a larger area behind than in front of it. This is an area into which air has to flow quickly to ensure that the piston keeps moving. If the air inrush cannot keep up with the increasing cavity size there will be insufficient pressure to keep the piston moving, and it will stop. So too will your piston rod, and whatever tooling you have installed on the end of it.

The rule of thumb for using a flow control to reduce and smooth air cylinder piston travel is to only throttle the exhaust air from the cylinder. The air flowing into the cylinder port should never be reduced.

How is this accomplished?

Use a "cylinder flow control". This is a device that may not look any different from the needle valve. Inside, however, there is a "needle bypass" which allows the air to bypass the needle which is throttling the air achieving full flow of air unidirectionally.

The "free flow" of compressed air through the cylinder flow control allows the unit, when it's installed in the correct orientation, to provide full and un-throttled inrush of air to the cylinder, yet, when the valve has shifted and the double-acting air cylinder has reversed, the air that is now flowing out of the cylinder is throttled to the level necessary to achieve the cylinder speed desired.

There will be a second cylinder flow control on the other line too, and this works exactly the same way.

As a result, air flow into the cylinder ports at either end of the cylinder is totally unencumbered providing high-force piston movement. The piston is trying to go fast and at full power, but since the exhaust flow of air is impeded by the cylinder flow control, the piston moves with full power, but at a controlled and desired rate.

Most cylinder flow controls will have a schematic on the side showing the flow paths to ensure that they are installed correctly.

Some cylinder flow controls are equipped with sealant coated male threads for screwing into the cylinder port, and with an "instant" type fitting into which the cylinder air line can be quickly fitted, features that save time and money.
