Title: Air-cooling apparatus for tubular plastics film blown by a blowhead
IPC: B29C48/90
Filed: 1970-10-01
Abstract: 1330168 Tubular films WINDMOLLER & HOLSCHER 1 Oct 1970 [8 Oct 1969 3 Feb 1970] 46781/70 Heading B5B Apparatus for cooling tubular thermoplastic films blown by a blowhead 2 comprises an air pipe 6 passing therethrough to introduce cooling air within the tubular film 3 at a pressure so that the interior film pressure exceeds the blowing pressure necessary for stretching the film in its plastic state and mechanical supporting elements 15 of low coefficient of friction with respect to the plastic film for externally supporting the tubular film issuing from the blowhead at least up to a position 10 where the film has solidified. The mechanical supporting elements 15 are, suitably spaced from one another in such a way that external cooling air issuing from cooling ring 4 on the blowhead 2 has substantially unimpeded access to the exterior of the tubular film. In the embodiment shown the supporting elements 15 comprise rings which are adjustable both in their diameter (Figs. 2 and 3) and in respect of their spacing one from another and are provided with rotatable sleeves, preferably comprising independently rotatable juxtaposed rolls (Figs. 7 and 8, not shown), with or without a covering sleeve, of a heat resistant, non-adhesive material, e.g. polytetrafluoroethylene. The supporting rings Figs. 2 and 3 and Figs. 5, 6 (not shown) preferably comprise an even number of components (15<SP>1</SP> and 15<SP>11</SP>) each of which is formed with a curved portion and straight end portions, the radius of curvature of the curved portion corresponding to the radius that the tubular film would receive if the associated component were in a central position between its limits of lateral adjustment. In the preferred embodiment (Fig. 4, not shown) the individual supporting rings are mounted on a frame so as to be simultaneously adjustable in the same sense as each other, the lower rings, which are disposed adjacent the blowhead, being adjusted to define a frustro-conical bounding surface for the freshly extruded molten film and the uppermost rings, which are situated above the solidifying position of the film, being hollow for the passage of a cooling medium. The pressure of air used to inflate the film is controlled by throttle plate 8 and air passes to the film through guide plates situated at the outlet 11 via a frustro-conical portion of the pipe 6 and a cylindrical portion 9 of an enlarged diameter and exits from the inside of the tube through one or more air vents 12 provided between the pipe 6 and the blowhead 2.

The ram 3 and mandrel 5 advance simultaneously and at the same speed until the bloom reaches a stop 11, at which stage the required upset has been provided on the end of the bloom. In a modification, the upsetter of Fig. 6 provides a pusher ram 3 with a nose portion 15; a stripper plate 20, and idler roller dies are provided, and stop 11 is omitted. In a further modification the upsetter of Fig. 9 has three roller die stands 23, 24, 25, and the rolls are all driven by a common motor 31. The upsetter of Fig. 13 has a mandrel 5<SP>1</SP> which has a tapered end; the rolls 8, 18, 19 are idle rolls.

Title: Gyrocompass system for rapidly determining true north at any latitude on the earth's surface
IPC: G01C19/38
Filed: 1962-12-14
Abstract: 958,562. Gyroscopic apparatus. GENERAL PRECISION Inc. Dec. 14, 1962 [Jan. 5, 1962], No. 47214/62. Heading G1C. A gyrocompass comprises a gyroscope 15 having its spin axis horizontal and approximately E-W, a pick-off 17 for determining the rate of precession of the axis due to rotation of the earth and means for comparing the earth rate at two positions of the axis separated by a small known angle so that the exact position of the axis relative to a N-S line can be determined. As shown the slider 22 of a potentiometer 20 is adjusted manually by knob 23 so that a meter 19 gives null deflection, the output of pick-off 17 thus being balanced by a suitable voltage which appears on meter 27 and is supplied to torquer 25 so that the precession of gyroscope 15 is counteracted. This voltage appearing on meter 27 is manually reproduced, by knob 33 acting on slider 32 of potentiometer 29, as a voltage V 2  on a meter 34 and is proportional to sin # where # is angular deviation of the axis of gyroscope 15 from the north. The gyroscope axis is now rotated through a small fixed angle e.g. 5 degrees and the operation repeated except that the voltage appearing on meter 27, and which is proportional to sin (#, + 5 degrees), is reproduced as a voltage V 3  on meter 35. Since the angle between the two positions is only a small angle of 5 degrees, the difference of voltages V 2  and V 3  which appears across stator winding 40 is nearly proportional to cos # and the voltage across another stator winding 39 is proportional to sin # as it is applied from potentiometer 29, so that by turning the rotor 41 of the angular resolver until a_null occurs on meter 42, indicator 44 gives the value of # and thus the direction of true north. The various meters may be replaced by a single meter and suitable switching used, or automatic follow-up systems may be used to adjust slides 32, 37 and rotor 41.

Title: Method and apparatus for extruding multicolored sheet material and sheet material produced thereby
IPC: B29C48/08
Filed: 1966-10-21
Abstract: 1,111,054. Making laminates by extrusion. ROWLAND PRODUCTS Inc. 21 Oct., 1966 [22 Oct., 1965], No. 47253/66. Headings B5A and B5N. A laminated sheet comprising layers of differently coloured or optically acting thermoplastics material is produced using an extrusion die head fitted with a stack 54 of flow and spacer plates 56, 58, 60, Figs. 4-6, which are fed from at least two heated extruders. As shown, one material is fed via a conduit 12 to manifolds 68, Fig. 4, and a second material is fed via a conduit 44 to manifolds 64. The manifolds 64, 68 pass through both spacer plates 60 and flow plates 56, 58 but in the flow plates the manifolds may be notched to diverge and allow egress of the material towards extrusion orifice 50. In Fig. 5 the manifolds 64 are notched in this manner and in Fig. 6 the manifolds 68. If plates 56, 58 alternate an extrudate is formed comprising alternate layers of the same material, see Fig. 1 (not reproduced). Alternative forms of flow plate are described, Figs. 7-9 and 11, 12 (not shown) where each layer is composed of three materials and the distribution of such material varies from one layer to the next. For example, flow plate (74), Fig. 7 (not shown), produces a uniform layer of a first material from manifolds (80), adjacent plate (76), Fig. 8 (not shown), produces a layer of the first and a second material from manifolds (80, 82) and a third adjacent plate (78), Fig. 9 (not shown), produces a layer of the first and a third material from manifolds (80, 84). The resultant layers are as at (86, 88, 90), Fig. 10 (not reproduced). A further variation may be introduced by disturbing the flow either directly, by using spacer plates (110), Figs. 14-16 (not shown), having undulating downstream edges (112) to give the layers a zig-zag cross-section. Fig. 17 (not shown), or indirectly by recessing the spacer plates as at (132), Fig. 22 (not shown), to affect the pressure distribution within the stack and provide layers of undulating cross-section, Fig. 23 (not shown). A similar effect to the last, Fig. 21 (not shown), may be obtained by controlling the pressures in the conduits and using flow plates having wide-ended notches (124, 126), Fig. 20 (not shown). It is stated that the optical properties of a material may be altered by the addition of aluminium flakes and the laminated material may be used in the manufacture of spectacle frames.
