Title: Improvements in the manufacture of artificial filaments, yarns, horse-hair, films, and like products
IPC: D01F2/28
Filed: 1934-08-01
Abstract: In the manufacture of artificial filaments, threads, bristles, or films, a solution containing a suitable base and a finely divided solid substance prepared by working said substance in a plastic mass containing a thermoplastic cellulose derivative and a softening agent therefor, is extruded into a setting medium or solution.  Preferably the base of the plastic mass is the same as that of the spinning solution which latter may be a viscose solution or cuprammonium solution or a solution of a cellulose ester or ether.  The substance incorporated may be a delustrant, a coloured pigment, a weighting substance or a metal to give metallic effect (lists of suitable substances are given in the Specification).  The amount of substance incorporated will vary according to the substance, and the effect desired, and may vary from 0,1 per cent to 40 per cent.  A suitable method of preparing the finely divided substance is to mix the base of the plastic mass with a volatile solvent or a substance which is a solvent at an elevated temperature, add the required amount of solid substance and knead at an elevated temperature.  Some solvent evaporates leaving a doughy mass which may be worked between malaxating rolls until the required state of subdivision is attained. During this operation the bulk of the solvent is evaporated leaving a relatively solid mass which may be broken up and dissolved as required into a spinning solution which may be spun by wet or dry spinning processes.  The size of the particles of the incorporated substance is usually below 1 micron, and may be less than 0,2 microns.  The fine state of subdivision enables a desired depth of colour to be obtained with a smaller amount of pigment than was hitherto necessary.  In an example 1 part of cellulose acetate, 1 part of carbon black and 1 \ba1/2\be parts of acetone by weight are worked in a heated kneading machine to a stiff mass, which is then heated between closely spaced heated malaxating rolls until the mass is substantially free from acetone.  The resulting sheet is broken into pieces and sufficient is added to a spinning solution containing 1 part by weight of cellulose acetate per three parts by weight of acetone to give a solution containing 0,03 parts of carbon black. Yarns produced from these spinning solutions may be woven or knitted into fabrics.

Patent GB-953321-A (GB)
Title: Production of titanium dioxide
Inventor: CALLOW ALAN EDWARD
IPC: C01G23/07
Filed: 1959-06-30
Abstract: In the preparation of titanium dioxide by vapour phase oxidation of the tetrahalide, the latter is first reacted with " activated oxygen " in the form of ozone, halogen oxides or hydrogen peroxide, and then reacted with another oxidant, normally air. The " activated oxygen " may also be produced by dissociating to the atomic state a portion of the oxygen feed by the application of high voltage or energy radiation. Titanium dioxide nuclei are produced by the activated oxygen. The latter may be introduced into the reaction zone separately from the other reactants or in admixture with the tetrahalide or the tetrahalide/air mixture in a " premix " process. The reaction may be effected in an empty space or a fluidized bed, the main oxidation in the latter case taking place, for preferance, above the bed. According to Examples (1) titanium tetrachloride was reacted in a fluidized bed of zircon sand with oxygen which has been bubbled through hydrogen peroxide solution; (2) titanium tetrachloride was reacted with hydrogen peroxide-containing oxygen in a concentric nozzle burner type reactor; (3) the first stage of a two-stage reactor system was supplied with a stream of oxygen containing 2.6% by volume of ozone and another stream of oxygen containing 0.26 gram TiCl4 per litre.  These were reacted at 600 DEG C. to form anatase of 0.03 micron size in suspension.  The suspension mixed with further oxygen was fed to one tube of a burner in a subjacent reactor maintained at 900 DEG  C. Titanium tetrachloride was fed to the other tube of the burner and the product pigment was separated from the effluent suspension.

Abstract: 381,999. Thermally-actuated valves; accessories. FOSTER, F. H., Kinsah, South Avenue, Littleover, and HASLAM & NEWTON, Ltd., Union Foundry, both in Derby. Aug. 10, 1931, No. 22543. [Class 135.] Locking-catches. -Gaseous carbon dioxide arising from evaporation of the solid refrigerant in a compartment o passes through a valve r into another part p of an apparatus for the production of solid carbon dioxide within a refrigerator, the gas after percolating through felt s circulating around the cabinet of the refrigerator. The refrigerant is admitted to the chamber o through a valve q which is interconnected with the valve r ; opening of the latter is controlled by a thermostat t. The spindle y of the valve r extends into the thimble z of a diaphragm u which is open through a pipe w to the refrigerant source. Pressure on the diaphragm causes the valve r to close and the valve q to open thus permitting refrigerant to enter the space o. A certain pressure in the latter forces the diaphragm back, closing the valve q and opening the valve r. The thermostat allows the latter to be held open, and with increase of temperature in the cabinet a grooved disc 7 is forced to coact with a cross-pin 8 thus allowing the valve r to close through the pressure on the diaphragm. In a modification, the movement of the valves r, q is controlled by a cam rotated by clockwork and held against rotation by the thermostat engaging a lug on the cam when the temperature in o is below the predetermined maximum. In a further modification, the movement of the spindle y is controlled by two diaphragms, one of which is open to the pressure within the compartment o.

Title: Process for smelting ores to metal, matte and slag
IPC: C22B5/02
Filed: 1928-08-03
Abstract: 324,902. Skappel, H. Aug. 3, 1928. Extracting.-In a method of smelting iron ores, particularly sulphide ores, in which there are obtained separate layers of metal, matte, and a slag containing less than 15 per cent of iron oxide, the composition of the ore is ascertained and the amount of matte that will be formed from a given charge is calculated; there is then added a sufficient amount of a sulphide having a heat of formation of at least 40 kilogram-calories per gram-atom of sulphur, such as sulphides of aluminium, zinc, manganese, magnesium, or alkali or alkaline earth metals, or materials such as sulphates and carbon which will produce such sulphides, to raise the mean heat of formation of the matte above 25 kilogram-calories per gram-atom of sulphur, where upon the charge is smelted with the usual additions. Iron ores containing some manganese may be smelted with the addition of manganese sulphide, yielding a slag containing about 7 per cent of iron oxide and sulphide and containing most of the phosphorus content of the ore, a matte containing about 50 per cent each of manganese and iron sulphides, and a crude pig iron low in manganese. Elements such as arsenic, antimony, nickel, cobalt, molybdenum, and platinum present in iron ores may be taken up in an iron speisse by adding also additional ferriferous material. In the application of the process to oxide ores, metals such as iron, chromium, and manganese may be transformed into sulphides by the use of sulphides of calcium, magnesium, or aluminium, and by regulating successive additions of sulphide the metals may be separated successively.

Title: Improvements in the manufacture and production of organic vinal sulphoxides and vinyl sulphones
IPC: C07C317/08
Filed: 1934-08-08
Abstract: Vinyl sulphoxides and sulphones are manufactured by treating vinyl sulphides under mild reaction conditions with agents supplying oxygen.  Suitable vinyl sulphides are those of the formula (CH2=CHS)xR, where x is a whole number and R may be an alkyl, cycloalkyl, aryl, aralkyl or heterocyclic radicle, e.g. ethyl, propyl, butyl, octodecyl, octodecenyl, cyclohexyl, phenyl, naphthyl, benzyl, phenylethyl or benzothiazyl, which radicles may be substituted, e.g. with alkyl, hydroxyalkyl or nitro groups or halogen; also polyvinyl sulphides, e.g. phenyl-1 : 3-divinyl sulphide.  Suitable oxidizing agents are: per-acids and their salts; inorganic and organic peroxides, e.g. hydrogen peroxide which yields sulphoxides at -10 to 50 DEG  C. and yields sulphones when used in excess at 50--120 DEG  C.; and hypochlorites, e.g. sodium hypochlorite which yields sulphoxides when used in excess at 30--100 DEG  C.  Anodic oxidation may also be employed.  The oxidation is carried out in alkaline to slightly acid solution, advantageously in the presence of agents combining with acids or of buffer mixtures. Diluents or solvents, e.g. water, alcohols (methyl, ethyl or butyl), ketones (acetone, methyl ethyl ketone), ethers (diethyl, dibutyl) or hydrocarbons (benzene, toluene), may be employed.  The products may be employed as intermediates for the preparation of dyestuffs.  In examples: (1) vinyl-p-thiocresyl ether is treated with hydrogen peroxide at 100 DEG  C. to produce vinyl-p-tolylsulphone; (2) vinyl-o-thiocresyl ether similarly yields vinyl-o-tolylsulphone; vinyl-2 : 4-dimethyl-5-chlorophenyl sulphide, 1 : 8-chloro-vinyl-naphthyl sulphide and the vinyl ether of 1 : 3-disulphydrylbenzene may be similarly oxidized; (3) 1 : 8-chlorthionaphthol vinyl ether is treated with hydrogen peroxide in acetone at 0--5 DEG  C., yielding 1 : 8-chlornaphthyl-vinyl sulphoxide; the vinyl ethers of thiocresols, di- and polysulphydrylbenzenes and 2-mercaptobenzothiazole may be similarly oxidized; (4) vinyl ethyl sulphide is treated with hydrogen peroxide at 70--80 DEG  C. in the presence of pyridine, producing vinyl ethyl sulphone; (5) by working at 0--5 DEG  C. in acetone, vinyl ethyl sulphoxide is obtained; (6) octodecyl vinyl sulphide is treated with sodium hypochlorite solution at 80 DEG  C. to produce octodecyl vinyl sulphoxide, which is further oxidized to the sulphone by means of hydrogen peroxide at 70--85 DEG  C.; (7) vinyl-p-tolyl sulphide is treated with sodium hypochlorite solution at 90 DEG  C. to yield vinyl-p-tolyl sulphoxide; (8) vinyl -b -naphthyl sulphide is treated with hydrogen peroxide at 100 DEG  C., producing vinyl-b -naphthylsulphone.
