A module in a support structure for container handling machines, comprises a connecting bar provided with bearing expansions at its ends, each of the bearing expansions being detachably connectable with a corresponding bearing expansion of another module in such a way as to define a support for a star wheel conveyor. Steps and may be applied in either order, ie. The diameter of the portion of the drive roller that operates on the rotator is smaller than the diameter of the rotator, so that even large rotational movement of the drive roller produces only small rotational movement of the rotator. In the process for making the polyester polymer, the polymer melt is polycondensed in the presence of a) and b), with the particles c) added in a melt phase process or added to the polymer in an injection molding machine or extruder. Battery plates utilizing the disclosed battery paste composition are produced without the need for curing, and instead can be used in the battery immediately following plate drying. comprising polar elastomers, such as polyacrylic and nitrile rubbers, apolar crystalline polyolefins and elastoplastic polyolefins.
