摘要： A concrete mixing includes a barrel having an interior surface and an exterior surface. A blade extends from the interior surface for mixing concrete and a ring is positioned about the exterior surface of the barrel for rotation of the barrel. An expandable joint is provided under compression between the ring and the exterior surface of the barrel to accommodate different thermal coefficients of expansion between the barrel and the ring.

摘要： The preparation of the polyols involves the following steps: (a) introducing in a reactor a mixture of acids comprising about 50 to 70% by weight of glutaric acid, about 15 to 30% by weight of succinic acid and about 10 to 20% by weight of adipic acid, or esters or anhydrides of these acids, with at least one polyhydroxy alcohol selected from the group consisting of secondary alcohols, tertiary alcohols and highly cluttered primary alcohols, with a catalyst selected from the group consisting of stannous and stannic chlorides and alkyl-tin compounds; (b) the reaction mixture is flushed with an inert gas; (c) the reaction mixture is heated while stirring at a temperature which does not exceed about 225.degree. C.; (d) removing 90 to 95% of the water or methanol formed in step (c); (e) introducing into the reactor at least one slightly cluttered primary alcohol; (f) heating at about 225.degree. C. and removing the maximum amount of water or methanol by distillation; (g) ending the reaction by creating a vacuum in the reactor in order to remove all traces of water or methanol in the reaction mixture and continuing this operation until the polyol obtained has an acid value lower than 3, a hydroxyl functionality at least equal to 2.0 and a hydroxyl number lower than 600. Polyols prepared in this manner are also disclosed.
