A self-extinguishing, expandable polymer composition is made by homopolymerizing or copolymerizing in aqueous suspension a monomeric material comprising from 55 to 100% by weight of one or more monoalkenyl aromatic monomers having the general formula in which Ar is a monovalent aromatic radical and R is a hydrogen atom or a methyl group, and from 0 to 45% by weight of one or more other ethylenically unsaturated monomers, the polymerization being carried out in the presence of an amount of one or more tetrabromobutanes as a self-extinguishing agent such that the homopolymer or copolymer produced has from 0À4 to 2À0% by weight, based upon the weight of the homopolymer or copolymer, of the tetrabromobutane(s) admixed therewith, a blowing agent being introduced at any stage of the process so that the homopolymer or copolymer formed has the blowing agent incorporated therein. The blowing agent may be pentane. The expandable polymer beads may be coated with a metal, e.g. Mg, Zn or Ca, stearate prior to pre-expansion.

Endless conveyer 27. Endless chains 28 support can carriers 29 each comprising an X- shaped beam 33, Fig. 4, surrounded by a perforated casing 34 which can rotate relative to the beam but which may be rotated therewith. The spaces 36 formed by the beam 33 are asymmetrical so as to facilitate discharge of a row of cans to a conveyer 31 and to positively locate cans being loaded from a conveyer 30. The casing has an inlet/outlet slot 35 and is rotatable by the engagement of a toothed plate with an agitating chain 54 which may move in the same or opposite direction to the chains 28. To ensure that each carrier 29 is in the correct attitude before entering the loading and discharging zones, means 52, 53 on the carrier cooperate with a guide track 56 provided on the housing 20 of the machine. Baffles 63 between each carrier are connected between the endless chains 28. In use, the carriers containing the cans are continuously rotated but, before they enter the zones 21 they are disengaged from the chain 54, their attitude is corrected, if required, and an indexing mechanism, Fig. 11 (not shown), causes rotation of the X-shaped beam 33 such that a space 36 is opposite the slot 35 and the cans are discharged. The beam 33 is rotated through 90 at each discharge station of the conveyer 31 and, by corresponding rotation, each carrier is loaded at the stations of the conveyer 30. The beam 33 is then rotated through 45 to take the slot 35 out of register with any of the spaces 36. At each discharge station a pivotal gate (69), Fig. 11 (not shown) is operated by a fluid ram (72) to allow a row of cans to leave a space 36.

The rotor 2 may rotate with or about a spindle 3 and has two chambers 5, 7 separated by a wall 6 having a passage 8 therein. Heavier fluid still containing some light fluid is discharged under pressure through a pair of drive nozzles such as 12 into a housing 1 and thence through a pipe 10. Lighter fluid containing some heavier fluid passes from the chamber 5 through the passage 8 into the chamber 7 from which the lighter fluid is discharged via the outlet 15 which communicates with a pipe 14 extending through the spindle 3. The remainder of the heavier fluid is discharged from the chamber 7 via an adjustable passage 17 and a pipe through the spindle 3 parallel to the pipe 14. The passage 17 is formed between the top of the rotor 2 and a disc 18 and its width may be adjusted by means of a screw, as shown, or, automatically or continuously according to the throughput of the heavier fluid, by means not shown. A spring-biassed member 25 may control a variable thickness passage which controls the rate at which the light fluid escapes from the rotor. Alternatively, a manually operated valve may be used to tap off oil intermittently. In a modification, Fig. 2 (not shown), the heavier fluid fraction leaving through the passage (17) is passed back along a duct (25) positioned along the top face of the rotor 2 and extending into the upper portion of the annular space between the rotor and the housing, this heavier fluid fraction being discharged with the bulk of the heavier fluid through pipe 10. In a further modification, Fig. 3 (not shown) the disc (18) is dispensed with and the heavier fluid fraction is discharged through nozzles (27) adjacent the upper corner of the rotor into the annular space between the rotor and the housing.
