Patent GB-1243188-A (GB)
Title: Improvements in or relating to the manufacture of pneumatic tyres
Inventor: ASKAM JOHN FAIRBURN
IPC: B29D30/20
Filed: 1967-12-01
Abstract: 1,243,188. Pneumatic tyres. DUNLOP HOLDINGS Ltd. 25 Nov., 1968 [1 Dec., 1967], No. 54829/67. Heading B7C. A pneumatic tyre of rubberized steel cord plies is manufactured by applying to a tyre building drum 1 a bead filler 2 of rubberized metal cords inclined at 22 degrees to the midcircumferential plane of the drum in each bead region followed by a carcase ply 3 disposed at 90 degrees to the mid-circumferential plane, applying bead wires 4 to the bead regions of the ply 3, offsetting the ply cords to an angle of 19 degrees in the same direction as the filler cords, expanding the drum so that each bead wire will be located in a shallow groove 6 in the drum, and turning up the ply 3 and filters 2 around the bead wires 4. The amount of ply cord offset and the interaction of the offset ply cords and the filler cords cause the turned-up cords of the carcase ply to be disposed substantially at 90 degrees to the mid-circumferential plane. The angle of offset is substantially equal to the angle of distortion which results if no fillers are fitted.

Title: Apparatus for controlling the level of molten metal in a  mould
IPC: G05D9/12
Filed: 1974-12-24
Abstract: 1468559 Continuous casting SUMITOMO METAL INDUSTRIES Ltd 24 Dec 1974 [26 Dec 1973] 55702/74 Heading B3F [Also in Division G3] The level of molten metal in a mould 11 is controlled by a servo system in which the signal from a level detector 11 is compared with a preset signal in a controller 12 providing an output proportional to the difference between the signals to position a sliding gate valve 18 supplying molten metal from a tundish 17 to the mould. An actuator 16 operates the valve 18 and is hydraulically coupled to a servomotor 15 to which the signal from the controller is applied through a servo amplifier 13 and an electro-hydraulic converter 14, the position of the servo motor being fed back by a detecter (19) to the servo amplifier. If the level of the metal in the mould becomes stable at a level which does not correspond with the pre-set signal, a push button (PB2) is depressed to cause a valve (V2) to supply the system with low pressure, instead of high pressure, oil and a valve (V3) to open a low pressure oil route to a conduit (21) so that the actuator 16 is disconnected from the servomotor. The controller 12 is now adjusted manually until the servomotor 15 is in its neutral position when there is no deviation from the pre-set signal. The valve 18 is also adjusted manually to provide the correct flow. A second push button (PB1) restores automatic control. Limit switches (LS1, LS2) operate in the same way as the push button (PB1) when the servomotor reaches the end of its stroke or when oil between the servomotor and the actuator 16 becomes compressed.

Title: Polyester yarns of irregular gauge and their production
IPC: D01F6/62
Filed: 1971-12-01
Abstract: 1325512 Irregular gauge polyester filaments RHONE-POULENC-TEXTILE 1 Dec 1971 [1 Dec 1970] 55836/71 Heading B5B Monofilament or multifilament polyester yarn of irregular gauge consists essentially of oriented polybutylene terephthalate having generally similar crystalline characteristics over its entire length, and also having an average Young's modulus below 300 g./tex. By "generally similar crystalline characteristics" is meant that such differences as may be found between the degree of crystallization of the thin and thick parts, respectively, of the filaments and yarns are not such as to impair to any significant degree their textile properties; in particular the thick parts do not show isotropic crystallization giving rise to a harsh handle and poor mechanical properties, as is found with irregular gauge polyethylene terephthalate filaments, The polybutylene terephthalate yarn may contain up to 15% of other copolymerizable monomers. Preferably, the filament gauge varies within the range 1-5 dtex. and the yarn may comprise thicker and thinner parts with gradual transitions between them, the thicker parts being 1-500 cm. apart and 3-1500 mm. long, the respective diameters of the thicker and thinner parts differing by 20-50%. Such yarn may be made by stretching a monofilament or multifilament yarn of polybutylene terephthalate to a degree which varies along its length. In examples, a melt-spun yarn is slightly pre-oriented by winding up the freshly spun yarn at a speed above its extrusion speed, and is thereafter subjected to a varying stretch, the average draw ratio used being from 1À83 to 2À04, suitably by using the apparatus of French Specification 1,546,531. In this apparatus the yarn is stretched between rollers rotating at different peripheral speeds, the degree of stretch being varied by a rotating disc equipped with a conical lug which serves as a yarn guide deflecting the yarn from its path to a variable degree. To ensure irregular spacing of the thicker portions of the yarn, the speed of vibration of the disc is varied. Alternatively the yarn may be variably stretched by means of a vertical device consisting successively, in the direction of travel of the yarn, of a feed roller, a pig-tail yarn guide, a Foster cam which imparts to the yarn guide a reciprocating movement set at right-angles to the yarn path, a further pig tail and a draw roller.

Braking unit 8 (Fig. 3) comprises an inside guide funnel 9 and an outer concentric box-shaped casing member 10 supplied through inlet 11 with a secondary coagulation liquid. The lower portion of the braking unit 8 is designed such that filaments emerging from the guide funnel 9 are contacted with a thin annular liquid jet 23 injected from the annular nozzle 12 of the casing member 10 at an included angle 0, (suitably # = 20 to 150 degrees), such that the entrained primary bath liquid is subjected to a liquid braking action by the jet. From unit 8 the filaments pass through the secondary coagulation bath, comprising a cup-shaped funnel 14 positioned at a substantial distance below the braking unit 8 and provided with bottom outlet 14a, and round stationary guide bar 15 which deflects their passage from the vertical to the horizontal and leads them to stationary saddle guide 16. Saddle guide 16 (Fig. 4) is provided with a thin filament passage groove 16a along its concave portion and a liquid receiving blind hole 16b for receiving a conventional regenerating liquid from a stationary supply nozzle 24. The freshly spun and coagulated filaments are then passed under tension to contra-rotating, partially engaging vaned rollers 17 and 18 which have vanes 17a 18a coated with, consisting of or covered with (Fig. 6, not shown) a resilient material (e.g. rubber or other elastomeric materials) and which convert the filaments from a tensioned state 13 to a tensionless state 13a (Fig. 5), prior to any post-treatment steps in the process. From the vaned rollers 17, 18 the tensionless filaments pass via primary conveyer 19 and liquid injector 26 to secondary conveyer 27 whereon they are passed through post treatment zones 41 and 42 comprising a conventional acid treating section 28, cold water washing section 29, hot water section 30, dewatering section 31, oiling section 32, de-oiling section 33, drying section 34 and humidifier 35 to a winder 40. Figs. 9 to 14 (not shown) illustrate other suitable braking units 8 whilst Figs. 7 and 8 (not shown), relate to the preferable dimensions of the apparatus in the coagulating phase of the process. An Example relates to the wet spinning of cuprammonium cellulose filaments using warm water as the primary and secondary coagulating liquids and H 2 SO 4  as the regenerating liquid used with the saddle guide 16.
