Patent GB-1228820-A (GB)
IPC: B29C48/156
Filed: 1968-12-20
Abstract: 1,228,820. Power cables. ANACONDA WIRE & CABLE CO. 20 Dec., 1968 [22 Dec., 1967], No. 60698/68. Heading H1A. A power cable has an insulated conductor surrounded by a jacket 14 of semi-conducting polymeric material with a plurality of corrugated drain wires 15-20 (of, e.g. Cu, Al) embedded in the jacket parallel to the axis of the cable. The drain wires are intended to be earthed and reduce voltage stresses in the insulation. The drain wires make good electrical contact with the semi-conducting jacket and their corrugated form renders the cable flexible. The corrugations may be in a plane which is radial to the axis of the cable (Fig. 2, not shown) or which is perpendicular to such a radius, Fig. 1, and the wires may break the surface at points 21, 22 (23, Fig. 2). Alternatively the corrugations may be perpendicular to the cable axis (Fig. 3, not shown). In manufacture (Fig. 4, not shown) the corrugated drain wires (37) are fed through slots (36) in a core tube (32) whilst the semi-conducting jacketing compound (34) is being extruded over the core (31), and are thus securely embedded in the jacket (34). The cable may be heated to vulcanize the jacket, and is then passed through a cooling apparatus (38). The insulation 13 may be thermoplastic or cross-linked polyethylene or synthetic rubber.

Abstract: 1,231,955. Electron beam deflecting systems. AIR REDUCTION CO. Inc. 17 June, 1969 [17 July, 1968], No. 30535/69. Heading H1D. In apparatus for producing and directing an electron beam through a curving path to a target surface, as shown, to melt material 12 in a crucible 11 of an electron beam furnace, the deflection of the beam is produced by a transverse magnetic field which, adjacent the target surface, increases in intensity from the inner edge to the outer edge of the beam, has an average intensity about twice the average intensity in the region near the middle of the beam path, and the lines of which are concave to the target surface. The crucible is mounted in a copper block 13 provided with coolant channels 14, the electron gun 18, having an elongated cathode 21, being mounted beneath an overhanging portion 17. Block 13 and a coil 33 having a core 32 are both mounted on a support 34 having an aperture 35 to permit the extension of leakage flux from the coil into the beam path, and yoke members 29 and 31 bearing polepieces 27 and 28 extend from the ends of the core 32 to either side of the crucible. Divergence of the beam is counteracted, in region 36-i.e. for about the first 60 degrees of deflection-by the increase in field in passing from the inner edge 38 to the outer edge 39 of the beam, due to the leakage flux through aperture 35 from coil 33; in the region of substantially uniform field between the yoke members, by the greater path length for the outer edge of the beam; and in the region above the polepieces, by choosing the latter to be each at least as wide as it is deep. In order to produce final deflection of a converging beam on to the surface of the material 12, the polepieces converge towards the crucible end, as shown in Fig. 1, to increase the average field there, to ensure that the field increases from the inner edge 38 to the outer edge 39 of the beam, and to provide the concavity of the field lines with respect to the crucible surface, as shown in Fig. 1, which is required to produce lateral focusing and hence a roughly circular beam cross-section in the region of impact. In a modified arrangement (Fig. 9, not shown), the polepieces 27 and 28 have portions parallel to one another at the end remote from the crucible.

When an oil fired space heater, of the type having a wick burner mounted at the base of a chimney 10 so that a flame spreader projects slightly through a central aperture 12 of a frusto-conical portion 11 of the chimney, is tilted beyond a predetermined angle to the vertical, a weight 55 tilting under gravity relative to the heater causes a latch 30 to release a spring biased arm 19 carrying a cup 18 so that the cup moves to cover the wick and simultaneously puffs air on to the wick to blow out the flame. The latch 30 is of L-section having one limb 32 pivoted at 31 to extensions 33 of a channel section bracket 14 secured on chimney 10, and a torsion spring 40 about pivot 31 normally holds a notch 36 in limb 32 in engagement with a roller 39 mounted on the arm 19. The head 49 of a rod 50 bearing the weight 55 is held rigid with a dish shaped metal pressing 53, resting in an annular casing 51 secured to extensions 33, by means of a collar 54 and a pin 47 extends between coaxial recesses 48, 46 in the head 49 and in the adjacent end 45 of a set screw threaded in the other limb of the latch. Both ends 21, 24 of a U-shaped lever pass through arm 19 to enable it to be reset against the action of a spring 27-29, the roller 19 automatically depressing the nose 39 of the latch. The limb 21 pivotally supports the arm 19 on the bracket 14. In a modification, the notch 36 in the latch opens downwardly and a conical nose on head 49 normally engages a convex portion on the latch to prevent a torsion spring from rotating the latch and releasing arm 19. The nose may engage with a roller on the latch and a roller may be interposed between the underside of the head 49 and the casing 51.

Abstract: 1328255 Longitudinally stretching films; laminates TOYO BOSEKI KK 27 Aug 1970 41346/70 Headings B5A B5B and B5N [Also in Division B6] In a process for continuously stretching longitudinally a film of polymeric material, the film is passed over at least one cylindrical idler roll each of which is positioned close to and between two adjacent horizontal rolls, the diameter of the or each idler roll being less than the diameter of either of those other rolls but larger than the separation between them. The film passes around all three rolls, so that the side of the film which makes contact with the idler roll is not that which touches the two adjacent rolls, as illustrated in Fig. 5. The film may be introduced into the apparatus either as a solid film or as a melt and is stretched at any temperature between the second order transition temperature and the melting point of the polymeric material. The stretching force is applied along the film and is usually provided by means of at least two driven rolls, ones on the delivery side being driven at a greater speed than rolls on the feeding side, around which the film passes. Fig. 1 illustrates a preferred embodiment of the invention, the film A being supplied from source 10, passing around four rolls 1, 2, 3 and 4 which are positively driven, then around idler roll 9 and then around rolls 5, 6, 7 and 8 which are driven faster than rolls 1, 2, 3 and 4. A plurality of idler rolls, as illustrated in Fig. 3, may be used. In such a case the idler rolls may have different diameters, dimishing from feeding side to delivery side. In these embodiments the idler rolls are supported by the horizontal rolls or either side, and the temperature of the film may be controlled by heating or cooling the driven rolls by known methods. An embodiment of the idler roll is shown in Fig. 8. Here the roll has grooves, parallel to each other and perpendicular to the axis of the roll, cut into the circumference. This gives a stretched film having raised portions when used in the apparatus of the invention. Such film may be used to prepare tapes or triangular monofilaments by slitting along the raised portions or along the flat portions. Laminated films may be produced by a method as illustrated in Fig. 4, wherein a melt D, issuing from extruder 49, is laminated to film E which may be pre-stretched and the laminate longitudinally stretched over idler rolls 48a and 48b and cooled over cooling roll 43. Examples illustrate the use of the invention in stretching films composed of polyethylene terephthalate, polypropylene, polyvinyl chloride, isotactic polystyrene, polycaproamide and polyethylene. A laminate consisting of two polypropylene layers is exemplified and details are given of the preparation of filaments of polycaproamide having a convex section and triangular filaments of polyethylene.
