Abstract: 1,226,374. Extrusion/plasticizing apparatus. UNION CARBIDE CORP. 18 March, 1968 [24 March, 1967], No. 12714/68. Heading BA To improve the plasticization of thermo. plastic resins during extrusion, e.g. by the removal of resin particles of high molecular weight by partial depolymerization, a cylinder 10 is situated in barrel 18 having inlet grooves 12 which terminate short of the downstream end of cylinder 10 and outlet grooves 14 which terminate short of the upstream end of the cylinder. In operation, plasticized material flows along grooves 12 and is then constrained to flow between the inner surface of barrel 18 and lands 16 before flowing downstream along grooves 14. The shear gap between the barrel and lands 16 is determined by experiment and depends mainly on the resin being extruded. As shown, the shear effect is increased by rottion of cylinder 10 with screw sections 20, 22. In a second embodiment, Fig. 4 (not shown), the cylinder is frusto-conical and fits an internally and correspondingly tapered barrel 40 and may be axially adjusted to vary the shear gap. Resins specifically mentioned are polyethylene, polypropylene, PVC and copolymers thereof, poly-(ethyleneoxide), polyvinylidene chloride and copolymers thereof and poly-4- methly-1-pentene. In particular substandard polyolefins, e.g. poly-(alkyleneoxide) may be extruded as good quality transparent film.

[Also in Divisions F3-F4] A vacuum arc furnace, includes a water-cooled mould 16 mounted in a cooling jacket 18, a head portion 2 which receives a consumable electrode 1, and a housing 11 containing a gate valve 23 and gas tightly interconnecting the mould and head portion. During the melting process, flanges 13, 7 on the head 2 seal against a rim 15 of the mould 16 and a flange 10 of the housing 11 respectively to maintain the vacuum therein. After the melting and the withdrawal of the electrode stump, the head 2 is lifted slightly from the mould rim 15 to allow the gate valve 23 to be interposed over the mould rim 15, Fig. 2 (not shown). During this time, spring elements 9 continue to press the flange 7 against the flange 10, the slight movement of the head 2 being accommodated by flexible bellows 6 which connect the flange 7 to the remainder of the head 2. The head 2 is then relowered on to the gate valve, Fig. 3 (not shown), to sealingly press the latter against the mould rim 15, before being completely removed from the now sealed mould, Fig. 4 (not shown), for use elsewhere whilst the mould cools.

Abstract: 1,258,107. Rolling mills. SOC. NOUVELLE SPIDEM. 10 April, 1969 [11 April, 1968], No. 18556/69. Addition to 971,409. Heading B3M. A four-high prestressed rolling mill, in which prestressing jacks urge the rolls together with a constant force, incorporates roll gap adjusters positioned between the backing roll chocks, each adjuster having an upper and a lower ram. The two rams are housed in the vertical bore of a mounting block 18, the block being anchored at 8 to the adjacent housing upright 1. The upper ram includes two pistons 18 and 26, the lower piston 18 of which receives a threaded portion of the lower ram 39. Fluid is introduced into a space 33 between the pistons, the pressure of the fluid either being held constant, or being varied to adjust the roll gap to a desired value during rolling. To change the rolls of the mill, the fluid pressure is released and the ram 38 suitably rotated by a screw 42. The pressure in the prestressing jacks is also released. Since the pistons 18 and 26 are held against rotation, the overall length of the adjusters can be altered to allow the rolls to be removed. The pass line of the mill can be reset by changing wedges located between the lower backing roll chocks and the prestressing jacks. The drive for the screw 42 can be automatically controlled or programmed for both roll changing and for variation of the roll gap.
