    Abstract: A device for transporting vehicles during manufacturing is disclosed that allows for upward and downward movement of the vehicle but avoids adverse longitudinal or transverse swinging. The inventive device includes a moving carriage mounted on a fixed rail, an upper frame, a lower frame moveably connected with an elevation mechanism and at least one first pair of articulated arms for stabilizing the vertical movement of the vehicle. An additional pair of articulated arms may be provided which extend and retract in a plane that is perpendicular to the first pair of articulated arms. Additional stabilizing roller elements connected to a fixed rail are provided on a lateral arm of the upper frame to prevent swinging of the upper and the lower frames of the transporting device.

    Abstract: A dispersion of an ester polymer in at least one liquid wherein the ester polymer is a polymer consisting essentially of a first monomer with structural units derived from at least one ester (1) of an aliphatic carboxylic acid with an aliphatic alcohol, wherein one of the acid and alcohol is ethylenically unsaturated and the other of the acid and alcohol has a long chain group of 14-40 carbons. A second monomer is optionally present which is a monomer derived from a different ester (2) within the same definition as ester (1), such that the mole average carbon content of the long chain group is 15-35, and a third monomer with structural units derived from a corresponding ester (3) of an aliphatic carboxylic acid and an aliphatic alcohol. One of the acid and alcohol is ethylenically unsaturated and the other has an aliphatic group of 1-13 carbons, such that at least 30% of the said aliphatic groups have 15-35 carbons. The polymer is present in said dispersion in at least 10% by weight and the dispersion is in a liquid which comprises at least one first organic liquid selected from (a) a branched or linear aliphatic hydrocarbon of 6-16 carbon atoms and (b) an aromatic hydrocarbon of 6-10 carbon atoms.
