Title: Web winder tension control
IPC: B65H23/195
Filed: 1966-11-01
Abstract: 1,136,343. Winding webs. SCOTT PAPER CO. 1 Nov., 1966 [3 Nov., 1965], No. 48992/66. Heading B6B. [Also in Division F2] A turret web-winding machine (Fig. 1) similar to that described in Specification 793,490, is characterized by each mandrel being provided with an adjustable friction clutch 22, driven by a belt (21, Fig. 1) engaging a pulley 33, and a brake 52 for decreasingly counteracting the torque transmitted to the mandrel by the clutch in a programmed manner during winding. A pneumatic cylinder 55 operates the brake 52, the air supply being controlled by an air pressure regulator 54. The regulator 54 is programmed by a cam 53 driven by the bed roller 14 of the winding machine, the cam 53 completing one revolution for each complete web-roll wound. A rotary air distributer 95, 97 is fixed to the shaft 13 of the turret (12, Fig. 1) so that each brake cylinder 55 is supplied with air when its mandrel 11 is in the winding position. Clutch and brake mechanism (Fig. 4).-Each mechanism is carried by its mandrel 11 in a location between the spiders 26 and 27 of the turret 12. Spider 26 has a sleeve 28 within which mandrel 11 is free to turn in a bearing 29. The pulley 33 is rotatably mounted on an extension of the sleeve 28 and a flange 34 constitutes one friction surface of the clutch. A sleeve 42 keyed to the mandrel 11 carries for rotation therewith a slidably mounted clutch ring 38 having an array of friction pads 36 embedded therein. A hub 44 for seating an array of clutch springs 43 is mounted for axial movement on the sleeve 42 to vary the compression of the springs. A cylindrical sleeve 45 fixed to the sleeve 42 has threads 46 cut into its outside cylindrical surface. A further sleeve 47 connected to the hub 44 by a bearing 48, screw-threadedly engages the sleeve 45, so that relative rotations of the sleeves 45 and 47 axially adjusts the hub 24, thereby adjusting the clutch pressure. A cylindrical brake drum 51 is fixed to the sleeve 42, and has the pneumatically operated brake shoe 52 engaging its surface. Air pressure regulator (Fig. 6).-The cam con. trolled regulator has a thrust member 61 which bears against one end of a coiled spring 60. The opposite end of the spring 60 bears against a seat 62 secured to the centre of a diaphragm 63. A needle valve 65 of a valve member 66 co-operates with a hole 64 in the seat 62. Valve member 66 has an annular seat 67 which bears against the rim of a hole 68 under the compression of a spring 69. When an increase in output pressure is required, diaphragm 63 depresses valve member 66 allowing high pressure input air to flow into the chamber below the diaphragm and then to the output 58. When reduced pressure is required, upward movement of the diaphragm in response to the programming cam 53, moves the seat 62 away from the needles valve 65 allowing air to escape to atmosphere via hole 64, chamber 72 and hole 73.

IPC: F16K1/30
Filed: 1967-11-01
Abstract: 1,209,164. Liquefied gas-storage containers. L. BAGNULO. 7Nov., 1967 [1 Nov., 1966], No. 49637/67. Heading F4P. [Also in Division F2] Means for discharging a predetermined volume of gas from the gas space of a liquefied gas, e.g. petroleum gas storage cylinder 3, Fig. 1, when a two-position discharge valve 21 is opened by moving an external lever 13 from its closed to open position shown in Fig. 3 comprises a float 40 which when the lever 13 is in the open position is latched to a rod 26 extending through the float and having its upper square end 25, Fig. 4, in sliding engagement with a squaresectioned chamber 24 formed in the lower end of the valve 21 and carrying an abutment 36 which when the float 40 sinks a certain distance, irrespective of the liquid level, releases a valveholding pin 30 thereby allowing the valve 21 to be closed by a spring 19 even though the lever 13 remains in the open position. The lever 13 is fixed to an arbor 12 which projects through a fixed member 14 and has a square end 16 slidable in a recess in the upwardly spring-biased head 17 of a shank 20 integral with valve 21. The upper end of the head 17 has diametrically opposed cam lugs 18, 18<SP>1</SP>, Fig. 5, which when the lever, arbor and head are rotated ride over lugs 15, 15<SP>1</SP> on fixed member 14 resulting in opening of valve 21 to a position in which a notch 37 is engaged by the pin 30. The rotational movement of the valve when being opened is transmitted to the rod 26, which after a 90 degrees turn is latched to the float by engagement of diametrical longitudinal extending ribs thereon with spring clips on the float and the rod is thus moved downwardly by the float as the liquefied gas vaporizes until the abutment 36 strikes a lever 33 to withdraw the pin 30 and allow valve 21 to be closed by its spring 19. To effect a further discharge of gas lever 13 is moved from its open to its closed position resulting in rod 26 being rotated 90 degrees and unlatched from the float 40 and returned by its spring 49 so that its square end 25 is near the upper end of chamber 24 in valve 21 and the lever 13 is then turned to the valveopen position. In a modification the upper square end of the rod 26, Fig. 8, is in direct sliding engagement with the arbor 53, and the two-position valve 55 is unseated by an arm 56a of a three-armed lever 56 having an arm 56c engaging a cam slot 51 in an extension 52 of the arbor 53. The third arm 56b when engaged by the abutment 36 on rod 26 in its lower position rotates lever 56 to close the valve 55. As in the previous embodiment rod 26 becomes latched to the float when the manual lever 54 is turned from the valve-closed to valve-open position and the rod remains latched until the lever is returned to the valve-closed position.

[Also in Division D1] A curtain of thermoplastic resin filaments 2 (e.g. of a polyamide or polyolefin) is extruded from a device 1 and passes to a pair of perforated suction drums 3, 4. Fibrous webs 7, 8 (e.g. of cotton, wool, bast fibres, man-made fibres, rayon or mixtures thereof), are fed between belts 11, 14 to toothed rollers 17, 18 to be broken up and blown by devices 15, 16 through a Venturi 20 and on to the surfaces of drums 3, 4 where they are laid in an even mat. Rotation of the drums brings the mats into pressure contact with the curtain of filaments which is still tacky and by the pressure of the drums 3, 4 and a pair of pressure rollers 21, 22 the filaments and staple fibres are bonded together. The fabric then passes through a slot in a double extrusion head 23 from which comes curtains 24 of filaments to be laid on the fabric in staggered relation to the filaments 2 therein. The filaments and fabric are brought together at the nip of suction drums 25, 26 on which mats of staple fibres are formed. These mats are pressed on to the tacky filaments 24 first by drums 25, 26 and secondly by pressure rollers 39, 40. The fabric is then cooled by drums 41, 42 and wound up at 44. Draft may be applied to the filaments between extruder 1 and drums 3, 4, between extruder 23 and drums 25, 26 or by rolls 21, 22, 39, 40 or drums 41, 42 so that the molecules in the filaments are oriented. The final fabric may be further pressed and stretched. The steps described above may be repeated several times. The fabric may be used in packaging (e.g. as bags) and as backing for linoleum, carpets and rubber-coated upholstery.
