Patent GB-979828-A (GB)
Title: Method and apparatus for packaging filamentary materials
IPC: B65H54/28
Filed: 1963-04-04
Abstract: 979,828. Winding yarns. OWENS-CORNING FIBERGLAS CORPORATION. April 4, 1963 [April 1, 1962], No. 13472/63. Headings DID and D1J. In the winding of a strand to form a package the strand is wound for a short initial period on a rotating non-packaging surface, then transferred to the adjacent main rotating packaging surface over which it is traversed to form an elongated package and finally returned to the non-packaging surface to allow doffing of the wound package. The invention is of particular application to the winding of multifilament glass strand since the portion wound in the initial period of acceleration of the rotating surfaces is not properly attenuated and is therefore waste. Multifilament glass strand 28 is held initially in the position shown by a guide roller 136 and wound on a portion 24<SP>1</SP> of a rotatable collet 24. After a predetermined and timed period the guide roller 136, which is movable under the action of a fluid pressure cylinder and ram arrangement, is retracted to allow the strand to move into contact with thread guide means 35 mounted on a reciprocable and rotatable shaft 30. Guide means 35 provide for a fairly rapid crossing of the convolutions of the strand wound on to the sleeve 26 while reciprocation of the shaft 30 ensures uniform distribution over the length of the package. After a further timed period, when winding of the package is completed the roller 136 is advanced to return the strand to the non packaging region 24<SP>1</SP>. A warning light is arranged to indicate to the operator at this stage that winding of the package is complete and by operation of a foot pedal 88 the drive to the package may be interrupted and the collet braked to allow doffing of the package and positioning of a fresh packaging sleeve 26. Release of the foot pedal completes the drive to the collet and the cycle of operations recommences. A master timer controls the period during which the guide roller 136 remains in the extended position and this period is chosen to allow the collet 24 to accelerate to its normal operating speed. The timer also controls the main winding period and thus determines the size of package produced.

Title: Apparatus for splicing thermoplastic synthetic yarns
IPC: B29C65/22
Filed: 1964-04-01
Abstract: 989, 282. Yarns and threads; hand tools for spinning &c. W. V. WILLIAMS. April 1, 1964, No. 13502/64. Headings D1F and D1W. In the manual operation for portable, yarnsplicing apparatus, an electrically heated iron 19 is raised, under the control of an adjustable thermostat 23 to the temperature appropriate to the yarn material e.g. nylon monofilament, and the two sections of yarn to be joined are placed in a slot 41 of an anvil 40 beneath which the yarn ends hang or are lightly grasped. Initial depression of a thumb element 36 retracts a carriage bar 32, a slide 29 and anvil 40 but a spring 50 urging a clamp slide 45 forwardly causes a dog 44 to clamp the yarn ends Y in the slot 41 against a shoulder 43. Further depression of element 36 continues the retraction of anvil 40 and dog 44 in unison towards the iron and finally the lower face of anvil 40 slides across the square corner 53 of the sealing plate 24 of the iron which constitutes a stationary anvil and its forward portion is so shaped as to make mating, sliding engagement with a tapered V-shaped groove 42 in the underside of anvil 40, the contact pressure between the anvils being maintained by a spring 38: during this action, dependent waste ends of yarn are melted and severed from the portions clamped in slot 41 and groove 42. The entire carriage bar 32 is reciprocated several times by means of the thumboperated crank 34 and while the clamped ends are riding over the anvil 53, Fig. 6, so as to permanently fuse and weld the ends under heat and pressure and effect a clean splice. The crank is released abruptly by the operator to restore the mechanism to its initial position and release the yarn, spliced by a joint resembling a butt-joint Fig. 12 (not shown).

Title: Improvements in or relating to a spring motor, particularly for a motion picture camera
IPC: F03G1/00
Filed: 1954-05-10
Abstract: 755,142. Spiral Springs. KODAK, Ltd. May 10, 1954 [May 11, 1953], No. 13522/54. Class 108 (3). [Also in Group XXVI] The spring 20 shown in Fig. 4 applied to a motion-picture camera is of the type having constant force characteristics which exerts a predetermined diminishing torque. The spring is a tight coil of resilient metallic band which is progressively unwound throughout the range of action. The material of the band is prestressed in manufacture so that it possesses a strong natural curvature and force must be exerted to straighten it. Throughout its entire length, the spring is so highly pre-stressed that when it forms a natural coil, the turns lie tightly upon each other and the resultant coil is virtually solid. In use in the camera the spring in its natural coil is wound upon a drum 21. Energy is stored in the spring by winding it on to a drum 23.

Abstract: 1376790 Extrusion blow-moulding A DI SETTEMBRINI 23 March 1972 [13 April 1971 14 June 1971 9 Aug 1971] 13715/72 Heading B5A In an extrusion blow-moulding process, moulds are moved around a closed path receiving at least one piece of extrudate from an extrusion head and blow-moulding the extrudate as the moulds move on, the article produced being taken from the mould after opening thereof and moved along a path substantially parallel to at least part of the path of the moulds. As shown in Figs. 1, 2, two upper tables 3 and two lower tables 4 rotate at the same speed on columns 2, the lower table carrying split moulds 5 on guide track 6 past extruder head 7 which is mounted to swivel for access. The upper table carries a corresponding number of rotatable blowheads 9 each having at least two vertically reciprocable blowing and removing mouthpieces 10, 11. Moulds 5 are opened and closed by means of rollers 12 moving in cam tracks 13, 14, the rapid closing under the extruder head being assisted by jack (15, Fig. 3, not shown). The extrudate is blow-moulded by one of mouthpieces 10/11 which is lowered into it and after mould opening, the blown article is retained on it when it is raised. At position 16, shaft 9 is rotated so that the vacant mouthpiece 10/11 can operate on the newly extruded extrudate while the blown article makes another circuit before being released at position 17 on to delivery conveyer 18. On mould closure, jaws (19, 20, Figs. 4-6, not shown), grip the bottom flash and subsequently move downwardly to sever the flash and eject it. In the embodiment of Figs. 7-11 (not shown), the removal devices (22) constitute a vertically reciprocable rod (28) mounted on radially movable arm (23) which also carries a vertically reciprocable stripper (30), blow-moulding being effected by a nozzle (not shown), forming part of the mould. A separate removal conveyer (32, 33) is provided for each turntable, blown articles being taken from device (22) at position (38) via rotary table (40) having funnels formed by plates (46, 47) to which they are fed by stripper (30). Table (40) rotates until hole (48) in the underlying table (41) is reached, whereupon the blown article falls through shoot (49) onto table (50) and thence on to conveyer (32/33). In Figs. 12, 13 (not shown), the article is stripped from its removal rod to fall through shoot (60) on to a rotating perforated plate (62) through which vacuum is drawn to hold it upright, before passing it to conveyer (71). The extruder may provide a plurality of lengths of extrudate and the blow-moulds correspondingly multi-cavity.
