Convert Water Into Gasoline
Since gas prices are so high, there has been a lot of buzz about «miracle devices bdquo that ldquo convert water into gasoline». While that in itself is misleading and sounds a little bit ridiculous, there actually is a bit of truth behind all the talk. I m not sure what the source of confusion actually is, but the devices known as hydrogen gas savers, or HHO generators don t actually convert water into gasoline. Instead, they actually supplement gasoline usage by converting water in a combustible hydrogen oxygen gas mixture known as HHO gas. HHO gas is also known as Rhode s Gas or Brown s gas, and has been used in high ndash heat metallurgy ovens and torches for over a century. The HHO gas is generated by running a current of electricity through water, a process called electrolysis.

Slice of History - A Knife Retrospective
The first knives were most likely made of wood, bone and other perishable materials. These ancient tools were shaped by knapping, or percussive flaking of rock, such as obsidian and flint. As advances in metallurgy were made, materials such as wood, stone, and bone blades were gradually succeeded by copper, bronze, iron, and eventually steel. During the Middle Ages, knives joined the fork and spoon as the prominent pieces of cutlery in the western world. As a result, much of the world s population was exposed to knives as a daily utensil and tool. Today s knives come in many shapes and sizes but can be categorized between two types: fixed blade knives and folding, or pocket, knives. Blades may be serrated or plain, or even a combination of both. Some knives contain a tang, a portion of blade that extends into the handle.

Something About Sintered Metal Powder
According to the forms of friction on work, bearings can be divided into rolling bearings and plain bearings. And the latter can further be divided into self ndash lubricating bearings, oil lubricated bearings and gas lubricated bearings. Bearings that produced by powder metallurgy method generally known as powder metallurgy self ndash lubricating bearings, sintered metal powder bearings, and sintered metal bearings. Powder metallurgy oil ndash impregnated bearing is a kind of alloy product. When the shaft rotates, due to the friction between the shaft and bearings, bearing temperature will be increased and there will be a pump suction function. As a result, oil will leak on the internal diameter of the friction surface. When the shaft stops rotating, the oil will be back to the inside of bearings. It is the working process of self ndash lubricating bearings.
