The produce may be subjected to the subatmospheric pressure for longer than 40 seconds, e.g. 40 to 60 secs., so that gases in the tissue separate and are removed. The produce is supplied to containers 6, Fig.2, on an intermittently moved conveyer 5 which passes then through a heater 2 and stops each container over a support 10. A chamber 3 is lowered by a drive 11 and seals at 12 against the container on support 10. The chamber 3 is partially evacuated along conduit 8 and subsequently the pressure in chamber 3 may be restored by admitting a liquid, e.g. water or juice along conduit E, following which, chamber 3 is raised and the peeled produce passed to a discharge conveyer 9, containers 6 being washed by sprinklers 8. Chamber 3 may alternatively be stationary and support 10 reciprocated. In another embodiment, Fig.3 (not shown) the conveyer moves continuously through a low-pressure chamber having inlet and outlet seals. In a third embodiment, Fig.4 (not shown), part of the conveyer is guided into a semi-circular configuration, the containers on this part being sealingly engaged by members (16) on a rotor (17) to form chambers connected to a source of subatmospheric pressure via rotor (17) a distributor (15) and a hollow axle (3'). In the embodiment of Fig.5, the produce is heated in a housing (27) having a rotating perforated drum 25 with projecting blades 26 conveying the produce through heated liquid and thence to a conduit (19) from which it passes into one of a plurality of working chambers 31 in a rotating disc 24. Top and bottom covers of chambers 31 rotate with disc 24 and are reciprocated towards and away from disc 24 to close or open the chambers by means of cam tracks. The upper covers include conduits for connection to a subatmospheric pressure device and to a pressure-restoring conduit E, and a hopper 36 is located below the chambers to receive the peeled produce on opening of the lower covers.

Abstract: 1,180,955. Coating cores by extrusion. UNION CARBIDE CORP. 1 Dec., 1967 [1 Dec., 1966], No. 54879/67. Heading B5A. [Also in Division H1] Polyarylene polyether insulation is extruded on to an electrical conductor with a degree of orientation such that the breaking strength exceeds the yield strength and the elongation at yield is at least 30%. Such oriented insulation has a shrinkage value of at least 40% when heated to a temperature above its heat distortion temperature. The oriented insulation is applied to the conductor by extruding a continuous hollow form of a polyarylene ether having a wall thickness 5 to 50 times larger than the final desired thickness, drawing it down to the desired thickness about the conductor, and rapidly cooling the thus oriented insulation to below its heat distortion temperature. As shown, wire 8 is drawn through the centre of guiding pin 2 for die 5 at a rate of 25 to 2500 times the rate at which the polyarylene polyether is extruded to give the required degree of orientation. The insulated wire is quenched in trough 10.
