[Class 2 (ii)] [Also in Group V] The hopper 2c and the discharge cylinder 3 are surrounded by heating liquid contained in a tank 1. The liquid communicates, via openings 3a, with the rear of the discharge piston 8, and surrounds the passage 6 which leads to the die or mould. Heating liquid covers the top 15 of the hopper. Electrodes 18, controlled by a thermocouple 18a, heat the liquid, which may be molten salts, lead, or lead alloy such as Wood's alloy. An auxiliary heater 19 heats the liquid surrounding the passage 6. Lubricant, introduced at 13 into a passage 9b in the piston rod, passes into a wide circumferential groove 8a between the piston and its cylinder. The piston may be operated by mechanical, manual or fluid means, or, as shown, by a screw-threaded handwheel 14. Plastic material is fed into the hopper through a passage 17. It is stated that the heating of the liquid by the electrodes 18 produces a circulation of the liquid. In modified constructions :-(a) Separate portions of heating liquid heat the hopper and the piston, and may be separately heated and controlled. (b) Separate portions of heating liquid heat the hopper and the discharge passage, the two portions being heated under thermostatic control by common or separate means. (c) When the heating liquid is molten lead, the lead may lubricate the piston. (d) The plastic material in the cylinder 3 is heated from the inside by the provision therein of an axiallyextending hollow tube containing heating liquid, over which tube the (annular) piston slides. (e) To give continuous discharge to a common outlet, two or more consecutivelyoperated piston-and-cylinder assemblies may be used. (f) Instead of discharging at a single point, a plurality of discharge points may be used with one or more piston-and-cylinder assemblies.
