Title: A new or improved method of producing thin-walled tubes and tubular fibres of large diameter from synthetic plastic materials, and apparatus for performing the method
IPC: B29C48/10
Filed: 1958-12-16
Abstract: <PICT:0904865/IV(a)/1> <PICT:0904865/IV(a)/2> Tubular films are produced by extruding a synthetic organic thermo-plastic material 1 through an annular extrusion orifice 3 in the extrusion head 2 (Fig. 1) to form a tube 4 which is drawn over a hollow mandrel 5 through which cooling water is circulated by means of tubes 6 and 7.  The portion of the tube 4 between the extrusion orifice and the mandrel is inflated by means of a gas at superatmospheric pressure introduced through the tube 9.  The diameter of the tube is thus increased sufficiently to enable it to be drawn without undue friction over the mandrel 5 whose diameter is greater than that of the extrusion orifice.  The tube 4, cooled by its passage over the mandrel, but not yet solidified and hardened, is drawn from the mandrel and may thereby be reduced in diameter and just before leaving the mandrel or after leaving the mandrel is cooled by water discharged from the annular hollow member 12 through uniformly spaced spraying nozzles 11.  The position of the member 12 is axially adjustable with respect to the mandrel so that the final internal diameter of the completely solidified tube or tubular film is equal to or less than the external diameter of the mandrel.  The tube 4 may be drawn through a second cooling device 13 (Fig. 2) concentric with the tube by means of a drawing-off device comprising a cylindrical core 15 connected rigidly to the mandrel 5 by a bar 16 and provided with four rows of rollers 17 co-operating with the four rubberized driven endless conveyer belts 19.  Specification 691,125 is referred to.

Abstract: 1398848 Conduits F W HITCHCOCK 23 Aug 1972 [2 Sept 1971] 41023/71 Heading H2C An electrical accessory conduit, Fig. 1, comprises a channel shaped member 1 with extensions 2 and 3 extending across the open mouth of the channel, parallel with and spaced from two further members 4 and 5, which are welded to the interior of the channel thus forming two slide ways or guide channels to allow the insertion of accessories which have flanges 18 (Fig. 3) which are engaged within these slide ways or guide channels when the accessory is inserted into the conduit channel. For this purpose, extended portions 2 and 3 are removed at 6 to expose underneath internal portions 7 and 8, the dimensions of which are chosen to match the dimensions of, e.g. accessory box (Fig. 3), such that the latter may be inserted into the aperture 6 and slide in either direction along the conduit to its desired position. Those portions of the conduit where accessory boxes are not desired may be closed by inserting a closure member (10) (Fig. 2, not shown), which comprises a strip of suitable plastics material (e.g. PVC), cut to the required length and inserted at 6 by bending and pushing. Greater rigidity of this member is ensured by arcuate longitudinal ribs (11). The accessory box, Fig. 3, is provided with tapped holes 15 for attaching a normal front plate or socket thereto, and may, at its rear be constructed to have a gap to allow other cables in the conduit passage. After assembly, the cut out section 6 may be closed by an accessory box with a plain cover. In a further embodiment ribs (11) are of rectangular cross section, or exposed surface of member (10) may be raised, to be flush with portions 2 and 3.

[Also in Division G2] A gauge for measuring the distance between the sprocket holes of a computer tape and the edge of the tape comprises a strip of material having a flat surface 1, a reference line 4 and a raised portion 2 on which is marked a scale. The raised portion 2 defines a straight reference edge 3 against which the edge of the tape is placed. The graduations on the scale are equal to the distance between the centre of the line 4 and the scale marking corresponding to a particular graduation. Thus by viewing the line 4 through the sprocket holes of the tape, the distance between the holes and the edge of the tape is determined by noting the scale graduation that is aligned with the particular sprocket hole lying centrally on the line. To assist in reading the gauge a transparent plastics magnifying lens may be used and the line 4 may be coloured to contrast with its background or it may be opaque on a transparent background. In a modification for use with different colour tapes the gauge has two scales, a white line on a black background and a black line on a white background. Also, the gauge may be double sided, the scale on one side being marked in the metric system whilst the scale on the other side is marked in the British system.
