Abstract: Articles, having a cylindrical shape, such as cans, are rotated from a horizontal position to a vertical position as they are transported between a pair of contact cables. The contact cables are set to diverge above a take away conveyor and at this point the cans will rotate. A magnetic assist device is positioned proximate the take away conveyor to assist can rotation and stabilize the cans on the take away conveyor.

Abstract: The invention provides a compound of general formula I ##STR1## in which X represents a direct bond or a ##STR2## group.

Abstract: Screen undersize anhydrous sodium tripolyphosphate particles, containing at least 2 weight percent of an alkali metal pyrophosphate, preferably sodium pyrophosphate, are moisturized with from about 145% to about 185% by weight of the theoretical amount of water to convert the anhydrous sodium tripolyphosphate into the hexahydrate form. The material is agitated during moisturization to keep the temperature below about 80.degree. C., and the moisturized material is dried at a temperature below 80.degree. C. to remove most of the free moisture. The product recovered from the drying step is a granular sodium tripolyphosphate hexahydrate product having a bulk density within the range of 0.59 g/cc to 0.64 g/cc and a friability of no higher than 30%.
