Patent GB-1503923-A (GB)
Title: False twisting yarn
IPC: D02G1/02
Filed: 1975-03-04
Abstract: 1503923 False twisting LEESONA CORP 4 March 1975 [6 March 1974 7 Oct 1974] 8834/75 Heading D1F A yarn Y is advanced from a supply 12 through a first heating zone 84, a second heating zone 88 maintained at a higher temperature than zone 84, a zone 92 in which the yarn is allowed to cool and a false-twister 34 which produces a twist which runs back through zones 92 and 88, the tension in zones 88 and 92 being greater than in zone 84, the yarn being collected at package P. Preferably starting yarn Y is a 2 or 3 ply 1300 denier "bulked" continuous filament nylon 66 yarn with 2.6 turns per inch (TPI) Z twist in the singles and 2.9 TPI S twist in the ply to yield a balanced yarn. The starting yarn possesses latent bulk which is developed by passage through first heating zone 84. A tension of 1 to 2 gms is maintained in the yarn in the first heating zone by setting the relative speeds of feed rollers 82, 86 so as to produce an overfeed of 6.7%. A tension during passage through the second heating zone of 4 to 16 gms is produced by an overfeed of 3.9%. Zone 84 is at 160 to 190C and zone 88 at 220C up to 5C below the melting point of the yarn. Feed rolls 86 exclude the false twist from the first heating zone. Tube 80 is a guide tube. The yarn is processed at 30 to 120 yds/min. False twist spindle 34 may be set to give 0 to 6 TPI of S twist. The yarn is thereby tightened i.e. its bulk is reduced. It retains a memory of the false twist due to the heat setting in zone 88 and thus shows good end definition when cut, e.g. after tufting. The 0-6 TPI of false twist does not produce pigtailing or detectable crimp. These could be produced with greater false twisting. In alternative embodiments (Figs. 1-4, not shown) one or both heating zones and the cooling zone may be horizontal.

Abstract: 109,249. Aktiebolaget J. V. Svensons Motorfabrik, (Assignees of Svensons Motorfabrik, J. V.). Aug. 26, 1916, [Convention date]. Ploughs.-A motor-plough is provided with automatic means for tightening the band of a band brake regulating the speed of downward movement of the share when the locking-device holding the share in its raised position is released. The share 2 is carried bv a loop 4 pivoted to a stationary shaft 3. The loop 4 is connected by a link 5 with one arm 6 of a bell-crank lever, of which the other arm 7 is pivotally connected to a rack-bar 9 riding over a roller 10 and engaging a pin disk 11, which is adapted to be clutched to the motor shaft. The pin disk also carries a band brake 15 which is tightened by a bell-crank lever 17 connected by a link 18 with a hand-lever 14 provided with a stop 13 adapted to engage the upper end of the lever arm 6 to maintain the share in its raised position. To raise the share from the ground, the pin disk is clutched to the shaft, the rack-bar thus being moved in the direction indicated by the arrow, and the lever 6, 7 being operated to lift the loop 4 and the plough share through the link 5. As the toothed rack reaches the position shown, the end of the lever 6 falls into position behind the stop 13, thus locking the share in its raised position when the clutch is released. To lower the share, the hand-lever 14 is raised to release the lever arm 6 from the stop 13, this operation simultaneously moving the bell-crank lever 17 to tighten the brake band 15, thus checking and controlling ths fall of the share through its connexion to the rack-bar 9.

Title: Improvements in and relating to the improving of fibres, yarns, fabrics, felt, paperand the like
IPC: D06M15/39
Filed: 1935-03-26
Abstract: Fibres, yarns, fabrics, felt and paper are rendered crease resistant by impregnating with an aqueous solution of an artificial resin together with a wetting agent comprising an alkyl naphthalene sulphonic acid, then hardening the resin.  The material may be subjected to a pre-treatment for softening, swelling or loosening. The material is preferably impregnated with a resin solution of low viscosity until the maximum amount is absorbed.  After impregnation, surplus is removed by squeezing or the like, and hardening preferably effected under-tension.  In examples: (1) a mercerized cotton fabric is passed under tension into a bath comprising hydrazo dicarboxyl amide, formaldehyde and caustic soda to which has been added the sodium salt of a formaldehyde condensation product of an alkyl naphthalene sulphonic acid, known under the Registered Trade Mark "Leonil S."  After immersion for 1 hour, surplus solution is removed, and the material heated for \ba1/2\be hour to 130 DEG  C., soaped at 60 DEG  C. and dried on rolls; the fabric is crumple proof; (2) a mercerized mixed fabric of cotton and viscose is boiled for 10 minutes with a ,5 per cent solution of isopropyl naphthalene sulphonic acid, known under the Registered Trade Mark "Nekal." The fabric is then immersed for 1\ba1/2\be hours in a solution prepared by boiling phenol and formaldehyde solution in presence of caustic soda, cooling, acidifying with lactic acid, adding formaldehyde, "Nekal," and a glyptal solution.  The fabric is then freed from surplus solution, heated for 20 minutes to 115--120 DEG  C. and a further 10 minutes at 130 DEG  C., followed by soaping and boiling. Specification 439,270 is referred to.
