Sometimes, bile contents crystallize and form gallstones. Gallstones, which can be as small as a grain of salt or as large as a golf ball, can cause some serious problems. They can block ducts inside the organ, causing the gallbladder to become inflamed.f you have gallbladder symptoms, surgical treatments are preferred unless you are at high risk, and then drug treatments may be utilized. Gallstones: Extracorporeal Shock Wave Lithotripsy. Another non-surgical treatment for which gallstones must meet certain criteria is extracorporeal shock-wave lithotripsy (ESWL).

Acetylene tanks have fusible plugs designed to melt and release pressure at temperatures over 212 F. Also if you draw acetylene at too fast a rate, the bottle can overheat and explode. The first rule of thumb I heard for this was 1/7 of the bottle capacity per hour. Obviously this is a big issue with small bottles. had a little portable brazing/welding rig. As near as I could tell it had an MC size (10CF) acetylene bottle (8.5 pounds) along with a 20CF oxygen bottle (13 pounds). A good match given that you typically use oxygen at twice the rate as acetylene. And the pair of botles weighs 21.5 pounds, very portable.
