TAI Stand System 9-08 This video introduces a pneumatic arm, known as EMMA(tm), developed for use sanding aircraft prior to their getting painted. Instead of a guy having to hold a sander, often over his head or in some other uncomfortable position, EMMA holds the sander (or 2), and the technician just moves the joystick left and right. The worker gets to go home, hug his children without shoulder pain, and play golf on the weekends, and management is happy that sanding now happens four times faster (or more). Workers get to keep their jobs because they don't get injured and their improved productivity means there's no pressure to outsource the work overseas. Management gets to eliminate sanding as a schedule bottleneck, and they get a better paint job (EMMA uses a higher grade sandpaper) so the customer's happy too. There's also a green benefit - EMMA outfitted with vacuum system sanders allow paint hangars to forgo the use of volatile chemical paint strippers, and to capture the chromate-laden paint dust instead of exposing workers to it. This video focuses on Temple Allen's Stand System, which accesses surfaces from the ground up to 10' - especially designed for under wings and when working on business or private jets. The Stand System is also ideal for Wind Turbine Blades and Composite-Hull Yachts. Equipped for Grinding, the Stand System offers significant advantages for fiberglass tank lining and smokestack lining maintenance. Contact info: Temple Allen Industries, Rockville, MD 240.888 ...

Synthesis of Potassium Trichromate An interesting compound. I hope you find the upgrade in recording equipment to be helpful. Thank you for your time. The chromate ion is a hexavalent chromium with 4 oxygens around it. The dichromate ion is formed when one of these oxygens on the chromate acts as a bride to another chromium atom with 4 total oxygens (one being the bridge). The trichromate ion is formed in a similar way with simply another chromium group on there. Inspired by the works of: /user/alchemicalgarden EDIT: I didn't realize but when I rendered this video quality dropped a ton. It was shot in 1080P. Looking into that and the mic issue right away.

Dissimiliar metals 03 Test three using dissimiliar metals in an HHO production. This time I am using a KOH solution. A far amount of hydrogen gas is forming off the stainless steel but very little (visually) oxygen gas is forming on the aluminum chromate (6063-t52 temper with chromate finish). No audio...sorry.
How to make Sodium Chromate - Na2CrO4 In this video, you can see how to make sodium chromate from potassium dichromate and sodium bicarbonate.
Precipitation Reactions In this video, we form 19 precipitates with various chemicals. A precipitate is formed when 2 soluble reactants react to form a soluble product and an insoluble product, which is "precipitated out." Some of the precipitates seen in this video are quite original, such as the lead chromate and silver phosphate.
Barium chromate precipitate Barium chromate precipitates from the alkaline dichromate solution.
Chemical equilibrium. Le Chatelier's principle This video explains a very important principle in chemistry - the Le Chatelier's principle. It explains shortly what equilibrium is. There are also two experiments (ferric thiocyanate and chromate-dichromate equilibrium) that anyone can do in every school laboratory. There are instructions on how to perform the experiments as well as explanations what is happening. I hope you'll enjoy this video. Please rate and comment!

SHIP HORN , FERRY HORN & BIG TUGBOAT HORN (Leslie Tyfon A-300-110-MB) This one of two Leslie A-300 ship horn that I own. This came from a private horn collector from texas. These are popular on older big tugs and ferries.This is an older A-300 and it is all bronze. A rare horn compared to its steam counterpart the Leslie Steam Tyfon 300. I replaced 2 of the 3 bronze diaphragms that were cracked in the middle. The Bronze diaphragms were very very expensive! This thing had 5 different colored paint coats and a couple of toxic zinc chromate primer before restoration. The last coat of paint I had to strip off was a tought epoxy type paint. I then took the horn to a "Soda Blasting " facilty because of the toxic nature of the zinc chromate primer. It took the primer off without pitting the horns. Then the horn had to go through a few days of " pickling" in a home brewed chemical soak. It took me a total of 72 hours of manual labor not including the wait for the paint stripper to work or the "picking" process. I will post videos once I finish fabrication of the mounting flange so that I coould supply air to the horn. This thing is going to be very loud since it can handle up to 300 psi of air! Stay tuned... More on the "Soda Blasting" Enviromentally friendly Soda Blasting is preferred over other paint removal solutions because it strips paint without damaging aluminum,steel,stainless,fiberglass and other underlying surfaces. Plus, non-toxic Bicarbonate Soda can be used to clean dirty engine compartments and much more. Sound trim,rubber,plastic,and ...

Chromium(III) ions undergo several reactions to make chromate and dichromate ions A solution of chromium(III) ions is reacted with sodium hydroxide. Initially, a precipitate is formed, but excess amounts of sodium hydroxide yield green hexahydroxochromate(III) ions. When hydrogen peroxide is added in the presence of heat, the distinctive yellow color of the chromate ion can be seen. After cooling, the addition of concentrated sulfuric acid further oxidizes the chromium, yielding orange dichromate ions.
Chromate - dichromate equilibrium Yellow chromate - orange dichromate equilibrium is shifted by changing the pH of the solution.
