| Show gasoline economizer vapor saver system akron 0 nov 2 skill of the worlds most experienced balloon builders has been called into play in an effort to reduce the millions of dollars lost annually by the petroleum industry in the form of evaporation of gasoline at bulk storage plants that this constitutes a serious problem is seen in iril a government estimate that during 1938 bulk p plants lants throughout the country sustained a loss thru evaporation of gallons with a value of recently announced was a va por zaver saver system tern that has demonstrated in actual use its ability to cut evaporation losses to a minimum simple in operation the system has as its chief component a sausage shaped b balloon a I 1 I 1 0 0 n or breather bag made of fabric especially ally treated on the inside with a compound rendering it imper 1 to the effects of gasoline or i gasoline vapor and rubberized on the outside to give it external pro 1 lection tec tion the bags are built in the balloon room of the goodyear tire rubber co where during nearly three decades workers have constructed more than a thousand free and kite balloons hundreds of airship envelopes notation flotation bags for aircraft rubberized fabric boats comic figure balloons and i many other products necessitating expert knowledge of fabric each breather bag is 29 feet long nine feet in diameter and has a capacity of more than 1600 cubic feet in operation in a storage plant the bag is housed in a steel building and pipe li lines 1 nes run from each tank to the bag on top of the bag is a carefully balanced weight when evaporation occurs the vapors pass through the pipes to the bag are kept un 1 der compression by the weight and when evaporation stops the weight forces the vapors bak back in to the tanks in this manner resh fresh air which would produce additional evaporation cannot enter the system and as the air al ready there is saturated further evaporation cannot take place |
