Title: Method for space dyeing yarn
IPC: D02G1/12
Filed: 1962-05-11
Abstract: 969,623. Dyeing yarn. JOSEPH BANCROFT & SONS CO. May 11, 1962 [May 19, 1961], No. 18272/62. Heading D1L. A method of dyeing yarn to produce a novelty effect, comprises applying the dye to a mass of the yarn confined in the form of a core and setting the dye on the yarn while it is so confined. As shown in Figs 1 and 2 a packed core 40 of crimped yarn passing from a normal stuffer box crimping device by way of a hinged tube 33, has dye sprayed thereon by a pair of nozzles 50a before passing under a tape 50 to be wound, still in packed form, on to a package 41. When the package is completed it is removed and treated by heat or steam to set the dye on the yarn before it is wound into package form. In modified forms of the apparatus shown in Figs 1 and 2 the dye is applied to the tape 50 and is subsequently transferred to the packed core. The dye may be applied to the tape by an applicator roll and dye bath, with or without intermediate rolls or it may be sprayed on in liquid or powder form or the upper side of the tape may co-operate with a plate to form a trough in which lies a pool of dye, a doctor being provided to remove excess dye. If an applicator. roll is used it may be patterned. In Fig. 8, the core of yarn coming from the crimping tube 4a passes between a tape 90 and a drum 85 to be held in its packed form. Dye is applied to the tape by applicator rolls 92, 93, 94 which may be patterned and the core and the tape pass through a heating bath 87 which causes the dye to be transferred to the yarn and be set thereon. The core is then washed at 96 and dried at 97 before the yarn is wound into a package 102. In a further form Fig. 10, (not shown), the packed core emitted from the crimping tube is held between a pair of tapes to which dye may be applied as in Fig. 8 and which is guided, with the core therebetween, through a heated bath to transfer and set the dye on the yarn, a washing bath and finally a dryer, the core then being released so that the yarn can be wound into a package. Specification 969,622 is referred to.

Title: Improvements in or relating to methods of and apparatus for continuously reeling endless filiform material
IPC: B65H67/052
Filed: 1962-05-14
Abstract: 948,298. Wire-winding apparatus. E. NIEHOFF, and W. NIEHOFF, [trading as MASCHINENFABRIK NIEHOFF KOMM.-GES]. May 14,1962 [May 19,1961], No. 18511/62. Heading D1J. A continuous reeling machine has two transversely spaced apart spindles 2, 3 that are rotatable in opposite directions as indicated by the arrows A and B. Each spindle carries a clamping disc 8, 9 that is normally biased against the reel 4, 5 on the spindle 2, 3, the clamping disc being retractable by electromagnets 6, (7 not shown in Figs. 1 and 2). In operation, screw spindles 23 cause a laying device 21, 22 to reciprocate over a length x of the reel being wound, for example the reel 5 on spindle 3, until a measuring device 20 determines that the reel 5 is full. The device 20 then actuates an electric circuit (Fig. 4 not shown) ensuring that the laying device 21, 22 is bolted in alignment with the clamping discs 8, 9 and that the reel on spindle 2 is automatically set in motion in the direction B. The electromagnet 7 pulls the clamping disc 8 away from the reel on spindle 2 and a guide spindle 25 is rotated to drive a transfer pulley 26 in the direction of the arrow C so that the wire 18 being wound is guided into the gap between the disc 8 and the reel on spindle 2. The clamping disc 8 is then released by the electromagnet 7 to cause the wire 18 to be clamped between the disc 8 and the reel. The wire between the two reels is then cut by a cutting device constituted by the rim of the clamping disc 9 and a roller 12. The rim is preferably hardened and detachably fixed to the clamping disc in order that it can be replaced. The drive coupling to the spindle 3 is then disengaged so that the reel 5 can be halted and removed with the aid of a trolley 30. When the wire has been clamped between the disc 8 and the reel on spindle 2, the pulley 26 is moved to a point substantially mid-way between the spindles 2, 3 and the laying device 21, 22 traverses the wire over the length x of the reel on spindle 2. During this period the pulley 26 moves to the right so as to be ready to carry the wire over to reel 5 when the reel on spindle 2 is fully wound. When the reel on spindle 2 is fully wound, the above procedure is repeated such that the wire is transferred to reel 5, the clamping disc 8 and an associated roller 11 now acting as the cutting means. The sequence of operations is automatically controlled by electrical contacts and limit switches and the spindles 2, 3 are driven through induction couplings to enable the speed of the spindles to be regulated in accordance with an adjustable energization.

Title: Treatment of coke-oven gases
IPC: F25J3/02
Filed: 1920-07-05
Abstract: To separate into their constituents the waste gases from coke ovens, which remain after the recovery of the tar, benzole, ammonia, &c., the gases are first highly compressed and treated for the removal of water and carbonic acid, then compressed further if necessary and cooled to liquefy all the remaining constituents except hydrogen, and the condensate fractionated to obtain nitrogen, carbon monoxide, methane, or ethylene. Alternatively, the gases may be compressed and washed with water or other absorbent for the removal of carbonic acid and then with a solution of common salt or with alcohol or acetone for the recovery of ethylene, and afterwards dried and liquefied as before.  The absorption liquid may be selected so as to absorb two different gases, for instance ethylene and carbon dioxide, which is convenient if these gases are subsequently to be brought to mutual reaction.  The gases given off during the different stages of the coking process may be collected separately and treated according to their composition, and it is more economical to replace the waste gases used for heating the ovens by other gases such as producer gas, water gas, or furnace gas.  For the preliminary absorption the gases may be compressed to 40 atmospheres and cooled to 0 DEG  C., and the final liquefaction effected by further cooling to -150 DEG  C., the pressure of 40 atmospheres being maintained.  Specification 18936/11, [Class 8 (ii), Air and gases, Treating &c.], is referred to.ALSO:To separate into their constituents the waste gases from coke-ovens, which remain after the recovery of the tar, benzol, ammonia, &c., the gases are first highly compressed and treated for the removal of water and carbonic acid, then compressed further if necessary and cooled to liquefy all the remaining constituents except hydrogen, and the condensate fractionated to obtain nitrogen, carbon monoxide, methane, and ethylene.
