Title: Improvements in or relating to cleaning of cotton waste and like materials
IPC: C11D3/14
Filed: 1937-09-18
Abstract: In the process of cleaning cotton waste and similar materials with a powdered adsorbent to remove oil and moisture, the p  adsorbent is added in separate stages.  Cotton waste from carding or spinning is freed from dirt in a willow or beater and is intimately mixed with an amount of a finely powdered adsorbent such as china clay, fuller's earth, infusorial earth or powdered limestone.  The adsorbent is then separated by beating and screening, and a further amount of adsorbent added.  After mixing, a third amount of adsorbent is added, and the total adsorbent is then separated.  Equal amounts may be used at each stage, but preferably 1/3 to 1/2 the total amount is used at the first stage.  About 30 to 55 lb. of adsorbent are used for a batch of 100 lb. of cotton waste.  The product is lofty, buoyant and suitable for making mattresses or upholstery.

Title: Copper-containing azo compounds
IPC: C09B37/00
Filed: 1956-08-20
Abstract: Copper complexes of o,o1-dihydroxy-azocompounds are made by treating an o-hydroxydiazo compound of the naphthalene series, which may be substituted with an ammoniacal cuprous salt solution. Advantageously, the cuprous salt solution is prevented from air oxidation and the substutuents are of high molecular weight such as an aryl-azo group or an arylsulphonate group.  Indicated as o-hydroxy-diazo compounds are 1-diazo-2-naphthol - 4 - sulphonic acid, 1 - diazo - 2 - hydroxy-6 - nitronaphthalene - 4 - sulphonic acid, 4 - (41-sulphophenyl) - azo - 1 - diazo - 2 - naphthol and 1,5 - dihydroxy - 2 - diazo - naphthalene - 7 - sulphonic acid-o-arylsulphonated in the 5-position.  The products may be used as dyestuffs per se or as intermediates in the preparation of di- or polyazo dyestuffs.  In examples: (1) 1-diazo-2-naphthol-4-sulphonic acid, (2) 1-diazo-6-nitro-2-naphthol-4-sulphonic acid, (3) the diazoxide made by alkaline oxidizing 2-diazo-5-o-benzenesulphonyl - 1 - hydroxy - naphthalene - 1,7 - disulphonic acid and (4) the diazoxide made by alkaline oxidizing 1-diazo-naphthalene-4,11-azobenzene-2,41-disulphonic acid are treated with ammoniacal copper sulphate solution to yield copper complexes of the corresponding o,o1-dihydroxy-azo-dyestuffs (1)-(3) yielding mono-and (4) tris-azo dyestuffs and the benzenesulphonyl groups of the product of (3) may be removed by hydrolysis and the dyestuff thus obtained decoppered by treatment with mineral acid.  In Example (4) cotton is dyed in a green shade.

IPC: A23C1/04
Filed: 1960-07-22
Abstract: In a process of drying a solution or suspension of a solid by spraying the liquid downwardly in a tower and providing an upwardly flowing stream of air or other drying gas at a temperature of 0-60 DEG C., as claimed in the parent Specification, the dried powder collecting in the lower end of the tower is submitted to supplementary drying by whirling it up in drying gas for an extended period of time by introducing at least a portion of the drying gas against the bottom of the tower, preferably through a rotating pipe with downward-facing slots, which sweeps radially over the entire diameter of the tower.  This gas-inlet pipe is parallel with the rotating suction pipe for the discharge of the dried material.  The supplementary drying is carried on for a period from a few minutes up to two hours.  In an alternative embodiment of the invention, the supplementary drying is effected outside the drying tower in conical vessels, in the lower part of which entry nozzles for drying gas are provided.  Specification 899,908 also is referred to.
