Abstract: 1289125 Combined melt spinning extruder and spinning head JAMES MACKIE & SONS Ltd 18 Feb 1970 [25 Feb 1969] 10084/69 Heading B5B A combined extruder and spinning head for the melt spinning of synthetic organic thermoplastic materials to form filaments comprises a feeding mechanism at the base of the extruder in the form of fluted rollers 1 and 2 mounted on shafts 3 and 4 respectively which are geared together and driven from a common drive (Fig. 1, not shown). The rollers are located at the base 8 of the extrusion chamber to which granular material to be melt spun is fed at either side in the direction of the arrows 9 by means of shoots (not shown). The rollers 1, 2 rotate in the direction of the arrows 10 to feed the granular material upwardly through the region 12 of the extrusion chamber. The material then passes through the heating zone 14 heated by plates 16 fitted to the outsides of the walls 17 and by a heating element 18 located within the central partition 15 of the zone 14. The granules gradually melt while passing between the zones 12 and 14 and any gases evolved escape through the vents 19. The molten material in the zone 14 is forced upwardly through the zone 14 and into and through the spinning head 20 when the temperature is maintained by the heating plates 21. The rollers 1, 2 extend for effectively the whole of the length of the crosssection of the chamber (Fig. 3, not shown) so as to exert a substantially uniform pressure on the material in the zones 12, 14 and 20, whereby uniform extrusion of the melt through the orifices 25 of the spinneret plate 30 (Fig. 4) is ensured. The filaments 26 thereby formed are cooled and solidified by streams of air directed on to the bundle of filaments by the nozzles 27 which are provided with slot apertures parallel to the spinneret plate 30 and extending along the length of the plate. The filaments are drawn upwardly by take-up roller (not shown). As shown in Fig. 4, the array of extrusion orifices in the spinneret plate 30 is many times longer than it is broad (e.g. 10 times or more longer) and the major axis of the array is parallel with the axes of the rollers 1, 2. The number of orifices in the spinneret plate may, for example, range from 16,000 to over 30,000. The length to breadth ratio of the array of orifices must be at least 3 : 1 and preferably at least 9 : 1. The extruder may be provided with a single feed roller eccentrically mounted in the bottom of the extrusion chamber instead of being provided with two feed rollers. The material to be melt spun may be in the form of a powder. The material may be polypropylene in granular form.

Abstract: 1301353 Packaging goods by wrapping by foil or film KOOPERATIVA FORBUNDET EKONOMISK FORENING 6 May 1970 21733/70 Heading B8C Stacked goods 3 on a pallet 2 are stabilized by advancing them along a conveyer 6 towards a feeding unit 17 which selects the leading load 1, at a starting position C and pushes it into a transverse and preferably plastics film 5 which can be stretched up to about 50% without loosing its elasticity and which is forced by the load to uncoil from rolls 8, 8, at a controlled braked speed less than that of the load 1, so as to be stretched round three sides of the load 1 as the latter advances along the track 6 toward a sealing position D. Upon reaching the position D a photo-electric cell, not shown, is actuated to stop the load 1 and cause a pair of locking claws 16 to swing inwardly about pivots 18 and prevent the load 1 from moving backwards while the feeding unit 17 is retracted to be ready for advancing the next load 1 located at the starting position C. A pair of arms 19, 19, with sealing members 20, 21 at their outer ends, are then pivoted inwardly by motors 22 to bring the foil which comprises two welded-together web parts 23, Fig. 4, together along the rear side of the load 1 where relatively movable sealing members 34, 35, Fig. 7, weld the web parts together along two laterally-spaced vertical, weld seams. The weld seam nearer the load is formed before the other seam to prevent stress in the webs between the seams an electrically heated cutting wire 40 separating the webs between the seams and the web then being cooled between the clamping jaws by jets of air at 44. In the clamping jaw arrangement, one jaw 34 is pivotally mounted upon its support arm 19. The feeding unit 17 comprises a pressure plate 46 which is supported by arms 47, 48 from a motor driven trolley 49 which has front and back wheel pairs 50, 52 which engage respectively in curved and linear tracks 56, 55 so that the plate 46 is drawn aside as the unit is retracted and is swung across the conveyer 6 to engage a load at position C as it moves forward from the retracted position. In an alternative feeder unit, Fig. 8, not shown, a driven carriage (65) carries a plate (73) which is vertically movable by chains (70) and gears (67) for lifting and lowering the plate into non-operating and operating positions respectively. The over run of the rolls 8, 8 may be prevented by the friction developed between the rolls and their mounting plates or, by separate brakes the pay out of the web being braked by pairs of rollers 14 which are preferably driven by a common, or individual, motors, not shown, the web being held stretched bybalancing rolls 15. The stretching of the web around the load causes upper projecting edges of the web to be somewhat folded inwardly. The stacked load can be moved vertically as shown schematically in Fig. 2.

Abstract: 1312178 Measuring distance travelled FORD MOTOR CO Ltd 26 Oct 1971 49700/71 Head ing G4H Pulses representing increments of movement cf a vehicle are applied to electrochemical cells EC1, EC2, operating as a decade counter. As described each pulse 13 from a monostable MS1 receiving the input pulses 1/P enables gate Al for a predetermined duration so that a predetermined amount of charge passes through cell EC1 to change its resistance by a known amount. Between pulses gate B1 is enabled to connect an oscillator 16 in series with resistance R2 and cell EC1 to develop an A.C. voltage across the cell proportional to its resistance. This is measured, after amplification and rectification, by an analogue/digital converter comprising a ten level comparator circuit 20 giving a signal on one of ten leads, the highest of which disables gate A1 and primes gate A2. This results in the next input pulse being applied to cell EC2 and to a monostable MS2 to close gate B1 and open gate D2 to pass a reverse current through cell EC1 to reduce its count to zero. This removes the disabling signal to gate Al so that subsequent pulses are applied to the cell EC1. The analogue/digital converter output may be connected to display means, e.g. electroluminescent film or gas discharge devices.
