Title: Improvements in presses for ironing and pressing cloth
IPC: D06F71/02
Filed: 1929-02-14
Abstract: 315,784. Mathiasen, G. E. July 18, 1928, [Convention date]. Ironing-presses. - The press head 14 is pivoted to the bent upper ends 9 'of a pair of spaced levers 10 which are pivoted at their lower ends to a shaft 11 extending between arms 12 pivoted to a shaft 13 which extends between the front legs 1 of the work table support. The levers 10 are also secured to a cross shaft 8 which is journaled in a frame 7 pivoted at 5 to the rear legs 1<a>. A shaft 15 extends between two lever arms 25 which are pivoted to the stationary frame at 26, and about the shaft 15 two pairs of bell-crank levers are pivoted. A shaft 20 carrying a roller 21 extends between the vertical arms 19 of one pair of these bell-crank levers, and the horizontal arms 18 of this pair of levers are bridged by a shaft 16 on which a pedal 17 is pivoted. Depression of the pedal 17 and arms 18 as a whole produces the necessary pressure between the press members 4, 14, the roller 21 acting downwardly on the shaft 11. The pressure is released by depressing the front edge of the pedal so that the pedal pivots about the front top edges of the horizontal arms 22 of the second pair of bell-crank levers, the vertical arms 23 of which act upwardly on the shaft 11. This movement of the pedals 17 not only depresses the arms 22 to raise the shaft 11 but also raises the laorizontal arms 18 of the first pair of bell-crank levers, thereby moving the vertical arms 19 rearwardly and freeing the roller 21 from the shaft 11. The pressure is adjusted by means of a nut 28 and a spring-pressed rod 27 secured to the lever arm 25. Instead of the press head being swung rearwardly as shown, it may be swung to one side of the press.

Title: Dyestuff powders
IPC: C09B67/06
Filed: 1950-03-03
Abstract: Disperse dyes are made in powder form to readily yield an aqueous dispersion of the dye on mixing with water by reducing to fine droplets a milled aqueous paste of the dye, a water-soluble salt of a lignin-sulphonic acid, and a water-soluble neutral or alkaline inorganic salt of which the cation is incapable of forming a water-insoluble soap, and drying the droplets by contact with heated air.  Preferably the air is at 212-300 DEG  F. and the particle size on drying is 25-100 microns.  Specified salts are sodium sulphate, phosphate, chloride, pyrophosphate and carbonate, potassium pyrophosphate, chloride and thiocyanate and lithium nitrate. Advantageously the slurry to be milled contains from about 1 to about 4 parts by weight of lignin sulphonate and about 1 to about 4 parts by weight of the salt to each 2 parts of dyestuff with water to give a total solids content of the slurry of about 30 to about 50 per cent.  Reduction to droplets may be effected by feeding the composition on to a disc rotating at a high peripheral speed, e.g. 4,500-10,000 ft. per sec. and a diagram is provided showing an apparatus for this technique, or by spraying through an atomizing nozzle.  Preferably the powder contains about 2 to about 5 per cent of moisture.  In examples powders are made from (1) 2-chlor-4-nitro-6-brom - benzene - azo - di - hydroxyethyl - metachlor-anilin, and (2) 1-hydroxy-4-amino-anthraquinone with potassium pyrophosphate and a lignin sulphonate.

Patent GB-576646-A (GB)
Title: Improvements in or relating to the twisting of artificial fibre yarns
IPC: D01F11/08
Filed: 1944-03-28
Abstract: A process of treating artificial fibre yarns, e.g. viscose, cuprammonium, cellulose acetate or polyvinyl yarns, particularly high twist yarns, to overcome snarling in knitting &c. operations, comprises applying to the yarn, prior to twisting, an aqueous emulsion containing a hydrogenated vegetable, animal or marine fatty oil, having a melting point above 30 DEG  C., drying and thereafter twisting the yarn with or without the step of setting the twist by heat.  The emulsion may contain between 2-30 per cent of the hydrogenated oil and the twist, e.g. 50 turns per inch, may be such that kinking would be caused in the untreated yarn.  Examples of oils, which, when hydrogenated are stated to be suitable are: beef or mutton tallow, lard, castor, olive, palm, peanut, soya bean, cod, pilchard and train.  Emulsifying agents, such as the monoglycerides, may be used to stabilise the emulsion and paraffin, gelatine or starch may be added for lubrication &c. purposes.  The emulsion may be applied by soaking, spraying, rollers, &c.  In an example, an emulsion was prepared from 7.3 parts of hydrogenated cottonseed oil, 3.6 parts of sulphated cottonseed oil and 0.5 parts of gelatine in 88.6 parts of water, and 50 denier-36 filament cuprammonium rayon skeins were soaked therein at 130 DEG  F. for 20 minutes.  The skeins were then centrifuged and dried at 140 DEG  F. for 5 hours.  It was found that the skeins had an increased weight 8.3 per cent based on their original weight.  The yarn was then thrown and twisted to 50 turns per inch after which it was steamed for 15 minutes at 140 DEG F. wet bulb and 134 DEG  F. dry bulb.  U.S.A. Specification 2,168,479 is referred to.
