Abstract: This invention relates to useful protective compositions, a method for protecting aluminum and aluminum alloy products against water staining, and a protected aluminum sheet. The method involves applying a continuous film of a protective composition to the surface of the aluminum product. The protective compositions useful for the invention are blends or reaction products of a polybasic acid and a partial ester of a polyol.

Abstract: A bearing extracting tool comprising a reaction housing adapted to be placed against machinery wall structure around the end of a shaft and bearing assembly to exract the bearing assembly; an end plate on the end of the housing away fom the bearing assembly; a plurality of lifter bars with lifter elements on one end thereof and abutment members adjustably secured thereto; a lifter plate generally parallel to the end plate and disposed externally of the reaction housing; and a force applying driver member. The lifter bars extend through the reaction housing, reaction housing end plate and the lifter plate with the abutmemt members secured to the lifter bars beyond the lifter plate, but in abutment therewith.
