Title: Method of and apparatus for treating the outer surface and inner surface of a pipe of a thermoplastic resinous material produced by extrusion
IPC: B29C48/09
Filed: 1974-09-20
Abstract: 1486016 Smoothing extruded plastics tube MITSUI PETROCHEMICAL INDUSTRIES Ltd 20 Sept 1974 [26 Sept 1973 (2)] 41123/74 Heading B5A The interior and exterior surfaces of a pipe 10, Fig. 2, of thermoplastics material which is produced by extrusion from a die 11 followed by passage through an external sizing die 20, are rendered smoother by passing a gas which is inert to the thermoplastics into the interior of the pipe as it extrudes from the extrusion die, i.e. to reduce oxidation of the material, and applying a lubricant to the exterior of the pipe from annular grooves 27 at the upstream end of the sizing die 20. Biaxially oriented bottles may be continuously produced by leading the tube from the sizing die, Fig. 1 (not shown), through a cooling tank and then through a furnace in which it is heated to below its crystalline melting point and then axially stretched in being drawn through a draw cone by alternately acting blow moulds which close upon the pipe and effect blowing as they move away from the draw cone, the blown bottles then proceeding to a finishing station. The material is preferably a highly crystalline polymer of a mono-α-olefin having a carbon number of up to 6, such as ethylene polymers of high density, isotactic polypropylene, poly-4- methyl-1-pentene, or polybutene-1. The inert gas may be nitrogen, carbon dioxide, or helium, and the lubricant may be wax, silicone oil, or soap water, or preferably a surface active agent which is removed from the pipe in passing through a water cooling tank which follows the sizing die. The sizing die, Figs. 2 and 3, is connected at 21 to a vacuum source, and the lubricant is supplied to the annular grooves 27 at the upstream end of the die from an outlet 23 of a pipe 22, via a recess 24 and downwardly extending groove 26 in the upstream end face 29 of the die. The extrusion may be effected from an axially fed die head, Fig. 4 (not shown), comprising a radially adjustable outer die and an inner mandrel supported by a spider which has an upstream projecting portion around which the material from the extruder flows, with the inert gas being delivered by passages through the mandrel and spider, from a valve controlled inert gas supply source. Alternatively, Fig. 5, extrusion may be effected from a cross-head die head into which material from the extruder is admitted from a passage 54, to flow to the extrusion passage 34 via a threaded portion 36a of the mandrel 36, the inert gas being delivered from a source 41 and valve 43, to a mandrel passage 40, either via a lateral inlet 40a to a torpedo passage 40c, or via an end inlet upon removal of a plug 56.

Title: Improvements in or relating to the manufacture of bodies from polyolefines
Inventor: ZADE HANS PETER
IPC: B29C48/00
Filed: 1959-12-04
Abstract: 914,483. Moulding polyolefines. COMMUNICATIONS PATENTS Ltd. Dec. 4, 1959, No. 41226/59. Class 87(2). Large moulded articles of a polyolefine material, e.g. polyethylene, are made by pre-heating a mould 4 to between the solidifying and decomposition temperatures of the material, filling the mould from below from the output of an extrusion machine 1, maintaining the mould temperature between the above limits during the filling operation and subsequently reducing the temperature of the mould and contents at a substantially uniform rate to below the solidifying temperature. The mould 4 is enclosed in a temperature controlled oven 7 which is apertured to fit around the barrel 2 of the extrusion machine 1 and is in two separable parts 16, 17, the upper of which has a convex top surface 15 defining a shape which at least partially compensates for shrinkage of the article upon cooling. The top of the surface 15 communicates with the bleeder holes 5 of the mould. In an example of the moulding of cylindrical polyethylene blocks 36 inch. diameter by 10 inch. high, the mould 4 is pre-heated to 125C. while the temperature at the extrusion nozzle is 120C. The air in the mould is replaced by nitrogen and the extrusion then started, the temperature of the oven 7 being reduced from 125 to 110C. and maintained at this latter temperature until the mould is filled, after which the supply of polyethylene is stopped and the mould 4 and oven 7 left fixed to the extruder 1 for approximately 6 hours until the oven temperature drops to 100C. On reaching this temperature which is below the m.p. of polyethylene, the mould 4 and oven 7 are detached from the extruder 1 and cooled for 34 hours by decreasing the temperature at the rate of 2À4C. per hour. After a solid skin has formed on the article, it may be removed from the mould, stored at room temperature until cooling shrinkage is complete, and finally machined to the required final dimensions.

Apparatus for tuning musical instruments which provide notes of given frequencies comprises a source of electric oscillations 11 including a set of twelve tuning forks 16, whose frequencies correspond to the chromatic scale, arranged in a circle such that any one may be positioned between adjustable pick-up and driving coils 20, 21 respectively, Figs. 2, 3 (not shown). A microphone 14 picks up vibrations from the musical instrument, and passes them via amplifier 15, having automatic gain control 26 to ensure constant output, to frequency comparator 12 which also receives signals from the oscillation source 11. An indicator 13 of the "magic eye" type supplied via amplifier 31 indicates when the frequencies are equal. The coils may be movable instead of the forks, and the latter may be parallel to the axis of rotation. A throat microphone mounted on the base (17) Fig. 2 (not shown) may be used instead of the pick-up coil. A limiter 23 controls the output of source 11, and for tuning other octaves may function asymmetrically to generate even harmonics. Frequency dividers or multipliers may be inserted between amplifier 15 and comparator 12 for tuning other octaves. For tuning low frequencies, harmonic distortion in amplifier 15 may suffice. The forks are screwed into aluminium tubes (19), Fig. 2 (not shown), and a ball and spring catch may be provided on the axis of rotation.

[Also in Division B5] A shoe comprises an outsole 14 and mid-sole 13 sealed to an upper 10, by a plastic welt strip 15, the mid-sole being in contact with both the upper and outsole, the outsole having an edge strip projecting beyond the mid-sole and the welt strip being connected not only with the side surfaces of both soles, but also to the upper and/or lower surfaces of the edge strip of the outsole. In the construction shown the upper 10 is secured to an insole 11 by stitching 12 and the assembly is then slip lasted. A mould comprising a base ram 17 on which the outsole 14 and mid-sole 13 are mounted and lateral jaws 16 is closed by the lasted assembly. Lateral jaws 16 possess recesses 21 into which the margin 14 2  of the outsole 14 projects. A thermoplastic material, e.g. P.V.C. containing a plasticizer, is injected into recesses 21, the material hardening through the last 18 and jaws 16 being heated. The stitching 12 should be positioned within the area of mid-sole 13 so that the material cannot flow into the interior of the shoe through the perforations in this region. The outsole may comprise a layer of P.V.C. and a layer of fabric (Fig. 9 not shown). A ram 17 of the mould may be lowered so that the margin 14 2  of outsole 14 is bent obliquely upwardly by the lower edges of recesses 21 (Fig. 5 not shown) in which case the plastic material covers part of the lower surface of the marginal strip. The outsole 14 may be preformed with an obliquely bent margin (Fig. 4, not shown) so that, with ram 17 in its initial position, the plastic material may cover the whole lower surface of the margin 14 2 . Again ram 17 may be raised so that its bearing surface is above the lower edge of recess 21 in which case the plastic edge strip 15 projects below the tread surface of the outsole 14 (Fig. 12, not shown). The bearing surface of ram 17 may also be shaped to effect the oblique bending of margin 14 2  (Fig. 13, not shown). The edge of the outsole may be turned upwardly and stuck to the midsole (Figs. 10, 11, not shown). In the construction of Fig. 10 the whole of the upwardly turned portion is embedded in the well strip whereas only part of it is in the construction of Fig. 11. Moulds split along their longitudinal axis and moulds comprising a frame and base plate are also described in which the mould wells and bases are shaped to give configurations as with the ram in its various positions (Figs. 6 to 8, not shown).

The liquid absorbent stream issuing from a plant where liquid hydrocarbons are recovered from a natural gas stream by absorption is regenerated for recycling by dividing the stream into two portions, boiling off the vapours in one portion, and mixing the concentrated portion with the untreated portion to provide a reconcentrated absorbent. A natural gas stream 1 has its free water and salt water removed in vessel 2, and after the introduction of the absorbent liquid, e.g. glycol, through line 5 the combined stream passes through cooling heat exchanger 7, cooler 9 and three phase separator 11. The glycol together with a portion of hydrocarbon condensate drawn off through line 14 is divided by flow rate controller 20 into streams 21 and 22. Stream 22 passes through heat exchanger 26 at top of a stripper 27 and after passing through a heat exchanger 29 in accumulator 30, it passes through stripper 27 into reboiler 24. The non-concentrated stream is reunited with untreated stream 21 in stabiliser 23, where any foaming takes place, before flowing into accumulator 30. Baffles 35, 41 and 43 allow for a portion of both condensate 33 and glycol solution to be recycled through line 5. A skimmer for separating out condensate after preheating may be provided prior to controller 20 (Fig. 2, not shown). In the embodiment of Fig. 3, not shown, a filter is provided prior to a pressure vessel which together with a flow rate controller replaces controller 20, a surge tank being in communication with the outlet pipe from the accumulator.
