Abstract: A conveyor device for transporting workpieces, particularly workpiece carriers (80) has two parallel transport ways (1, 2) and a transverse conveyor (3) arranged between the latter. The support frame of the transverse conveyor (3) has an immovably arranged central section (90) and two end sections (100, 110) mounted pivotably on the latter. Each of these end sections (100,110) intersects an inner roller system (60 or 70) of a transport way (1 or 2) and bridges the space between the roller system (60 or 70) and an outer web belt (4 or 5) of the transport ways (1 or 2). A lift device (410 or 420) by which the end sections (100, 110) are pivotable into a plurality of different vertical positions relative to the transport ways (1, 2) is associated with each of the two end sections (100, 110).

Abstract: Particulate expandable styrene polymers requiring short residence times in the mold are obtained by polymerizing styrene and, optionally, other copolymerizable monomers in the presence of expanding agents and from 0.001 to 0.1% by weight of a brominated oligomer or polymer of a 1,3-diene for at least part of the time at temperatures of from 110.degree. to 140.degree.C.
