Woodscrew Chart by W. L. Fuller
Coach Screws and Bolts have been used in the construction and erection of my shed as mentioned in my post about Securing Shed Doors.

That post also explains what is, and is not, silent about a Silent Fill Valve. This is now complemented by the post Replacing A Toilet Fill Valve.
In order to satisfy the requirements of Internet SEO (Search Engine Optimisation) the valve is referred to, in this article, specifically as a Toilet Silent Fill Valve or more generally Silent Fill Valve but its full title is a Silent Fill Toilet Cistern Inlet Valve since it is:
This type of valve is complex and deploys a built-in mechanism which uses the inherent water pressure in the Mains Water to drive the valve from the closed to open position and then from the open to closed position. The mechanism is controlled by a much smaller valve in the form of a stopper covering a pinhole which requires a much smaller effort to operate it than the main valve.
The article endeavours to explain to the reader how the complete valve works so that they understand the order in which physical processes take place and why they follow on from each other as they do. The theory behind the workings of the valve are developed from the basic principles of forces and pressures acting on the individual parts but without the detail of too many mathematical formulae.

Knowledge of the Kuiper Belt and the Oort Cloud is sparse but it is known that some objects have very eccentric orbits. I think we can expect many more objects to be discovered in this area in coming years.

There is a new class of objects in the Solar System – Dwarf Planets – which now includes Pluto. See the poster below from SPACE.COM.
Since this poster was produced there has been an addition – Sedna. Take a look at Kuiper and Oort Objects.

I’m sure we’re a long way from hearing the last on Cosmic Inflation and Expansion of The Universe, but here is a SPACE.COM chart briefly explaining inflation of the universe from a pinpoint to its present day size.
On 30th January 2015 Space.com announced: Inflation is not proven to have occurred as previously suspected in March 2014. The evidence for it has been discredited. Check it out at Space.com where Evidence for Cosmic Inflation Theory Bites the (Space) Dust.
