  • Hydrogen Annealing @ Worthington Steel Worthington Steel's hydrogen annealing is a treatment of steel where it is heated to and held at a specific temperature followed by a controlled cooling process. Steel Hydrogen Annealing is a heat treatment process to remove hydrogen, carbon, sulphur, and other impurities. This process also prevents hydrogen embrittlement. Worthington Steel's hydrogen annealing steel treatments are regarded as among the best in the steel industry.

  • Japan's Monju nuclear accident parts 1-3 A Coverup Revealed By Wikileaks Pre Fukushima Named after the Buddhist divinity of wisdom, Monju, located in Japan's Fukui prefecture, is Japan's only fast-breeder reactor. Unlike conventional reactors, fast-breeder reactors, which "breed" plutonium, use sodium rather than water as a coolant. This type of coolant creates a potentially hazardous situation as sodium is highly corrosive and reacts violently with both water and air. On December 8th, 1995, 700 kg of molten sodium leaked from the secondary cooling circuit of the Monju reactor, resulting in a fire that made headlines across the country. Although the accident itself did not result in a radiation leak, many argue that the fire came close to breaching Monju, a catastrophe which would have spilled plutonium into the environment. Following the fire, officials at the government-owned Power Reactor and Nuclear Fuel Development Corporation (PNC), operators of Monju, first played down the extent of damage at the reactor and denied the existence of a videotape showing the sodium spill. Later, they released still shots only, showing things like intact pipes and clean floors and claiming that there had only been "a minor leakage in the secondary sodium loop [that had] caused some fumes". While short videos were released, these were edited to hide the full extent of the damage. Further complicating the story, the deputy general manager of the general affairs department at the PNC, Shigeo Nishimura, 49, jumped to his death the day after a news conference where he and ...

  • ALERT Japan nuke expert Fukushima / Melted fuel rods estimated to be 12 meters underground. Japan nuke expert: Melted fuel rods estimated to be 12 meters underground Reactors No. 1-3 — To be 100 feet deep in a year 9/20,Japanese government declared Fukushima nuclear plants can be settled (kept under 100C) ("cold shutdown") by the end of this year. However,Koide from Kyoto university warns it is too unrealistic. As he says,we do not know where the fuel rods in the reactors.We do not even know how the vessels are right now. They managed to fix the water measurement is reactor 1,but the measurements are broken in reactor 2 and 3. We do not even know where the water is which they keep giving in. 9/20,Tepco admitted hundreds of tons of water flow into the basement floor of each reactor on the daily basis. Tokyo newspaper reported there were 100000 tons of water.It must be reduced to 51600 tons after pumping by 9/13.However,there is estimated at least 81300 tons water still. Tepco has been explaining it is because of water,but still it's too much. Tokyo newspaper reports there is possibility that groundwater is flowing into the basement floor from the cracks. From the view of a civil engineer (me),another possibility is that water is coming from "the sea".It sounds more rational that there is a crack / cracks to connect the basement floor and sea,and sea water comes into the basement floor. If so,no matter how much they pump up the water,water keeps coming in by siphon effect until the surface is as high as sea water level.(the same mechanism of toilet) Koide ...

Please keep in mind that parts must spend a good few hours in the hot sun, or a drying oven to drive off excess hydrogen that is absorbed during the cleaning process!!! otherwise parts may break when put under stress.

  • The_Ferritic_Solution.flv Their main chrome element produces a conversion-free ferrite structure. Their resistance to cinder is still increased through silicon and aluminium alloying, both of which also have a ferrite-forming effect. They are highly resistant to sulphurous gases, yet show lower creep-rupture strength as compared to heat-resistant austenitic steels at higher temperatures. Signs of embrittlement appear at specific temperature ranges. Embrittlement especially occurs after cooling down to room temperature, which is why shock-stress is to be avoided, like eg when carrying out repairs.

  • Cannons to the Planets Google Tech Talk December 15, 2009 ABSTRACT Presented by Dr. John Hunter, President of Quicklaunch, Inc. Quicklaunch is dedicated to launching rocket propellant and other consumables into orbit using a hydrogen gas gun. Quicklaunchers are related to the SHARP launcher, originally at Lawrence Livermore National Laboratory. More than 90% of the mass required for manned Mars and Lunar exploration is propellant. The Quicklaunch breakthrough will result in costs less than $250/lb to propellant depots in Low Earth Orbit. These low costs will enable manned space exploration of the solar system in our lifetime. Johns talk will include the history of gun launch to space, from the popularizers to the practitioners. A brief physics overview will be given on hydrogen gas guns as well as electric guns. An animation will portray a Quicklauncher delivering propellant to a depot in Low Earth Orbit. There will be plenty of time for questions and answers.

  • Encapsulation Carpet Cleaning Maintenance Recommendations and Tips Encapsulation Evolution Encapsulation technology is not new; it has been around for a good 15 to 20 years. However, advances in the polymer field have enabled manufacturers to create a product that performs vastly better than its predecessors. "It was mainly on the back burner because nobody really understood it," says Gelinas. "The fact that polymer technology has changed pretty drastically has given us the ability to encapsulate better." Encapsulation evolved from carpet soaps that were notorious for causing resoiling of carpets, says Mark Warner, national sales manager for The Bullen Cos., Inc., and brand manager for Clausen Carpet Solutions, Folcroft, Pa. There have been several modifications to the technology that have served as the basis for today's encapsulator. Warner says these advancements include: • The addition of a compound known as Ludox. This filled the grooves within fibers to prevent soiling. While that was an improvement, it caused other problems, such as interfering with the carpet's ability to refract light, resulting in unattractive carpets. • The development of detergent encapsulation that used butyl as an active solvent, in order to enhance the rinsability of the cleaning chemical. It was an improvement, but still led to resoiling. • In the 1980s, chemists began addressing the resoiling problem by adding acrylic co-polymers — similar to those in floor finish. This allowed the solutions to dry to a crystalline material for easier vacuuming. It was a ...

  • Using citric acid for rust removal Citric acid can be bought from drugstore (they use it in jelly or such to adjust acidity) but it is very expensive there. Therefore Finnish rodders buy it from some agriculture-store. It is not expensive. Officially it is used as pigs obstruent! I dipped those parts in citric acid for overnight, next day brushed it with wirebrush and flushed it with water. Then again back to citric acid over night and wirebrushed + flushed it next day. Flushing is important, you'll want to get all acid away, otherwise steel will turn to yellow. You can't use this method on all parts because of hydrogen embrittlement. So no pedals, frames, brake drums, engine blocks or such to citric acid!!! And yeah, parts should be clean -I've cleaned 'em with fuel- because grease will neutralize acid. Ratio was 3% Parts must be dried soon as you get them flushed, I quess you guys know why... Music on the background: Junior Brown; "Sugarfoot Rag"
