Abstract: 1384434 Injection moulding IMPERIAL CHEMICAL INDUSTRIES Ltd 1 Oct 1973 [2 Nov 1972] 50479/72 Heading B5A The invention relates to an injection moulding process for making laminar articles comprising a core of a synthetic resin composition substantially totally enclosed in a skin of a dissimilar synthetic resin composition wherein the skin composition is injected into a mould cavity from a first source through a passage 3 and a sprue channel 2 having an inlet of circular crosssection and, before the skin composition has solidified, the core composition is injected from a separate source through a passage 4 and the sprue channel 2 such that it tends to be first injected offset from the axis of the sprue channel towards one side thereof. According to the invention, a slidable member 5 is provided in a housing 1, the member 5 having a passage 6 of circular cross-section for communication with the inlet of the sprue channel 2, the outlet of the passage 6 being the same size as the inlet of the sprue channel, and the skin composition is injected through the passage 6 while the member 5 is in a position wherein the axis of the passage 6 lies on the axis of the sprue channel 2 and, before injection of the core material the member 5 is moved in a direction opposite to that side of the channel 2 to which the core material tends to be first injected until a line on the surface of the passage lies on the axis of the sprue channel, and then commencing injection of the core material whereby the core material is first injected along said line (Fig. 2). The member 5 is then returned to the position wherein the axis of the passage 6 lies on the axis of the channel 2 as the injection of core material builds up. The member 5 may be moved to a position (Fig. 7, not shown), wherein the passage 6 is isolated from the sprue channel after completion of injection. A further quantity of skin material may be injected after the core material, and the member 5 may accordingly be moved in the opposite direction before commencement of this injection (Fig. 6, not shown), and then retracted as before as the injection of skin material builds up. Fig. 8, shows a modification in which the sliding member 5 comprises a cylindrical sleeve surrounding a rotary multiway tap body 12. The sleeve 5 is rotatably mounted in a housing 1 having a channel 3 for supplying skin material through passages 13, 15 in the sleeve 5 and tap body 12 respectively. A channel 14 in the housing supplies core material through passages 14, 16 in the sleeve 5 and tap body 12 respectively. Figs. 8 to 15 (only Fig. 8, shown), show the sequence of positions of the sleeve 5 and tap body 12 during the injection cycle, Figs. 8 and 16 (not shown), showing alternative cut-off positions. In a further modification (Figs. 17, 18, not shown), the passages 15, 16 in the tap body are "skewed" so that the axes of channels 2, 3, 4, all lie in the same plane as the axis of rotation of the tap body 12.

Abstract: 1,113,401. Perfluorocarbon polymer cables covering. HAVEG INDUSTRIES Inc. 29 Nov., 1965 [24 Dec., 1964], No. 50570/65. Heading H1A. [Also in Division B5] Tubing of perfluorocarbon polymer, examples are given, in particular PTFE tubing, is stretched by simultaneously flattening the tubing under pressure to reduce the cross-sectional area of the tubing wall and elongating the tube. The flattening may be achieved by one or more passes through calendering rolls or by using platens. In the embodiment shown extruded PTFE tubing 2 is passed between rolls 8, 10 which are heated, e.g. by hot liquid, to a quench tank 14 and then to spool 16 on which the tubing is collected. In a second stage, Fig. 2, a length of the treated tubing 24 has a lead wire 22 passed therethrough to introduce into the tubing an insulated or otherwise cable 26, having a diameter slightly less than that of tubing. Tubing 24 is shrunk on to the cable by passage of the assembly through a ring flame heater 28, see also Fig. 5 (not reproduced). To facilitate the entry of lead wire 22 into the tubing, end 18 may be heated by flame 20 to cause it to assume a circular cross-section from the flattened condition and air may be introduced to facilitate the further passage of wire 22 therethrough. Heating by heater 28 is preferably to a temperature within the range 260-150 C. In a modification the treated tubing is shrunk about a plurality of cables (32), Fig. 7 (not shown). In a second embodiment the extruded tubing is flattened and stretched by platens (40), (42), Fig. 8 (not shown). If the rolls or platens are not heated, the quench tanks may be dispensed with.

In operation, at the end of the discharge stroke, piston portion 2a abuts housing face 5a and the next suction stroke is effected by supplying pressurized liquid to inlet 17 to act on piston portion 2a, slide valves 19 and 31 being operated to close ports 18 and 8. During the suction stroke, piston 3 uncovers ports 21 to admit liquid into chamber 7, and piston portion 4 compresses a gas in chambers 9 and 11, the gas passing from chamber 9 to chamber 11 via valve 14 and passage 13 when ports 10 are covered by piston portion 4. At the end of the suction stroke, piston portion 4 engages a sensor 34 of a control 33 which opens valves 19 and 31 to permit the discharge stroke by the gas pressure in chamber 9 acting on piston portion 4. The initial part of the discharge stroke is slowed by the gas passing through throttle aperture 15 in valve 14 until piston portion 4 uncovers ports 10 to allow the full gas-pressure to act. Enlargement 26 initially throttles and then opens constriction 23 to produce the discharge jet, a formula being disclosed for obtaining the flow passage shape. In Fig. 2 (not shown), the piston extension is shaped such that the liquid discharged from chamber 7 is first attached to the extension and then transfers to the discharge passage wall. The gas-pressure actuation may be replaced by explosion or magnetic actuation.

Abstract: 1,221,679. Pencil leads. G. SCHWANHAUSSER and E. SCHWANHAUSSER, [trading as SCHWAN - BLEISTIFT - FABRIK SCHWANHAUSSER & CO.]. 21 Jan., 1970 [25 Oct., 1968], No. 50719/68. Heading B6P. A pencil lead is, after baking, impregnated with a liquid substance which is polymerizable to a solid substance, the substance being subsequently hardened after removal of any surplus thereof. The substance when solidified is preferably flexurally resilient. Polyamides and their derivatives are suitable substances. The substance used may be such that it does not result in a uniform solid but in a mixture of solids, or so that only a part of the pore space is filled with the solid, the latter effect being achieved by adding a solvent which is evaporated after the substance is hardened. The non-filled pore space may be filled with substances which improve the writing properties. The penetration of the substance into the lead may be accelerated by subjecting the leads to sub-atmospheric pressure before impregnation. Examples given of suitable substances are styrene alone or mixed with acrylonitrile and benzoyl peroxide, and epoxide resin dissolved in a mixture of xylene, methyl isobutyl ketone and glycol.

Abstract: 980,043. Tyre-curing machines. UNITED STATES RUBBER CO. Dec. 31, 1963 [Feb. 4, 1963], No. 51273/63. Heading B5A. In a pneumatic tyre curing press, Fig. 1, the steam enters the curing bladder B in the form of a number of high velocity jets from nozzles 40 located round the periphery of an annular plate 32. An annular filter screen 41 is located inside the series of nozzles. The nozzles are displaced at an angle to the radii of the plate 32 and are directed downwardly and outwardly, e.g. tangentially to the inner surface of the bladder so that, in operation, condensate is prevented from lying at the bottom of the mould cavity and is drained via an outlet 46. The steam may be continuously admitted to the curing bladder B in accordance with the pressure conditions existing therein, or alternatively it may be supplied in pulses, from a steam supply set at a higher pressure than that required in the bladder. In the latter case the steam supply is controlled by temperature sensitive devices 50 and after filling the pulses occur at a rate of between 5 and 20 per minute. To eliminate gases trapped between the plies of the tyre T, the pressure in the bladder B may be raised at some predetermined point in the curing cycle. This increase in pressure is achieved without an increase in temperature by the controlled admission of an inert and non- condensible gas, e.g. nitrogen or flue gas, into the bladder B. By this method the temperature at the end of the curing cycle may be lowered, the pressure remaining constant, the maximum temperature being reached at an intermediate point in the cycle. The invention may also be applied to the type of press shown in Fig. 3.
