Abstract: 1,260,505. Anodizing aluminium. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. April 3, 1969 [April 10, 1968; April 12, 1968], No.17694/69. Heading C7B. Aluminium metal or alloy is anodically oxidized in a plurality of stages under different electrolytic conditions, viz - electrolyte composition, temperature, current density, degree of agitation, voltage waveform or value, or duration, each conductive to a different coating ratio (coating weight to weight of metal lost), from one of higher e.g. at least 1À10 in a first stage to one of lower e.g. at most 0À90 in a further stage, to improve the flexibility of the oxide coating. As shown, Al wire or strip 1 is passed through a suitable electrolyte for anodizing arranged in a cell at different temperatures at different regions along the direction of movement, differing by at least 10C., by establishing within the cell a plurality of e.g. four electrolyte circulation systems (shown by arrows 10, 15, 24, 25) of separately controlled temperature, each including a pump (6, 11, 16, 17) an electrolyte inlet (7, 12 18, 19) and outlet (8, 13, 20, 21) and a heater (9, 14, 22, 23). Alternatively the electrolyte may change from one of sulphuric or oxalic acid to phosphoric acid.

Title: Heat-sealable packaging
IPC: D21H19/18
Filed: 1948-07-01
Abstract: Coating compositions comprise a wax and a copolymer obtained from the copolymerization of a mixture containing 5-40 parts of a conjugated diene aliphatic hydrocarbon and 95-60 parts of a monomer of formula (R)n.C6H(5-n) (C.R1 : CH2) in which R and R1 are inert hydrocarbon radicals, a halogen, e.g. chlorine and bromine, or hydrogen, and n is 0, 1 or 2, e.g. styrene, and o-and p-chlorostyrenes.  Optionally the compositions may include fatty acids, e.g. arachidicbehenic acids or a stearic-palmitic fatty acid eutectic mixture, plasticizers and natural or synthetic rubbers and resins. Specified dienes are butadiene-1,3, isoprene, 2,3-dimethyl butadiene-1,3; pentadiene-1,3, 3-methyl pentadiene-2,4, 3,4-dimethyl pentadiene-2,4, hexadienes and heptadienes. Specified waxes are paraffin, microcrystalline, ozokerite, ceresin, utah, montan, carnauba, candellila, japan, cotton, bayberry, myrtle, spermaceti, beeswax, and synthetic waxes. The natural or synthetic rubbers and resins may be glycerol abietate, glycerol esters of polymerized rosin, hydrogenated rosin and glycerol esters thereof, phenol-modified pentaerythritol rosin esters, poly-alpha and beta pinenes, polystyrene, paracoumarone-indene resins, rosin-modified maleic anhydride, rosin-modified alkyd resins, rosin-modified phenol - formaldehyde resins, gum dammar, chlorinated diphenyl, chlorinated paraffins, chlorinated natural rubber, cyclized polyisoprene, congo resin, polyvinyl acetate, and copolymers of vinyl chloride and vinyl acetate, and vinyl chloride and vinylidene chloride.  The plasticizers mentioned are polybutylene, polybutadiene, polymethylcyclopentadiene, copolymers of isobutylene and butadiene, butadiene and vinyl pyridine, and isobutylene and styrene, triphenyl phosphate, dibutyl phthalate, butyl stearate, toluene sulphonamide, bodied castor oil, hydrogenated methyl abietate, diethylene glycol dipropionate, chlorinated diphenyl, dibutyl sebacate, triglycol di-2-ethyl butyrate, o-cresyl-p-toluene sulphonate, paracoumarone-indene resin, bodied linseed oil and polymerized linseed oil.

Patent GB-625674-A (GB)
Title: Improvements in or relating to treatment of glyceride oils
IPC: C11B7/00
Filed: 1946-06-14
Abstract: Natural glyceride oils are extracted with a selective polar solvent for unsaturated glycerides and the extract is then subjected to a second extraction using a liquid paraffinic hydrocarbon as solvent in a ratio within a range of 1 to 10 parts hydrocarbon per part of oil, thereby separating the various materials present in the oil.  The raffinate from the first extraction contains the relatively highly saturated glycerides together with gums, lecithin and phospholipids, while the raffinate from the second extraction contains free fatty acids and unsaponifiables such as sterols, inhibitols, tocopherols and vitamins.  The extract from the second extraction contains the more highly unsaturated glycerides.  Glyceride oils which may be treated include soyabean oil, linseed oil, cottonseed oil, menhaden oil, fish liver oils, tung oil, coconut oil and lard, while polar solvents mentioned are furfural, acetonyl acetone, methyl ether of ethylene glycol, ethyl acetoacetate, mixtures of nitromethane and nitroethane, and the polar solvents referred to in U.S.A. Specifications 2,200,390 and 2,200,391.  In examples, cottonseed, soyabean or linseed oil is extracted with furfural saturated with naphtha, the extract is subjected to extraction with naphtha and, if desired, the extract from the second extraction is subjected to extraction with naphtha-saturated furfural in order further to reduce the free fatty acid content. Apparatus is shown in which the extractions are carried out with countercurrent flow of oil and solvent.  The naphtha employed may be a mixture of heptanes and octanes having a boiling range between 293 DEG  and 350 DEG  F.  In isolating the constituents of the raffinate from the second extraction (1) the furfural may be distilled off, the free acids saponified with alcoholic sodium or potassium hydroxide, the alcohol distilled off and the soaps dissolved in water; the unsaponifiable materials can then be dissolved out in petroleum naphtha or other solvent and the sterols may be crystallized from the naphtha, or (2) the raffinate may be Twitchellized, the fatty acids distilled off and the unsaponifiable residue worked up, or (3) the raffinate may be subjected to alcoholysis or other treatment to convert the fatty acids to esters of monohydric alcohols such as methyl alcohol, the esters distilled off and the unsaponifiable residue worked up. Specification 18137/47, as open to inspection under Sect. 91, is referred to.

Title: Improvements in and relating to the process of preparing low water content alkali cellulose, and the preparation of cellulose ethers therefrom
IPC: C08B1/08
Filed: 1923-07-12
Abstract: Alkali cellulose of low water content and suitable for the production of ethers is obtained by treating cellulose with an alkali solution, removing excess solution and drying until the water content is low, and then incorporating with solid caustic alkali with or without saturated caustic alkali solution or a limited quantity of moisture. The drying may be effected at once or after storage, and may be carried out in a vacuum or in inert gas or in a stream of air, at room temperature or with artificial cooling.  The incorporation with solid alkali may be effected with cooling, or with the addition of the alkali in small portions, or both.  Kneading machines, disintegrators, edge runners or the like being employed.  The product may be converted into the ether in one operation or first into a lower ether and then into the desired ether.  The etherification is effected in the usual manner by means of alkylating or aralkylating agents such as esters of inorganic acids.  When agents of low boiling point are used such as ethyl chloride or bromide an autoclave is necessary, but with di-alkyl sulphates, benzyl-chloride, ethyl iodine &c. open vessels may be used, with a reflux condenser if necessary. The separation of the ether from the reaction product is effected by the usual methods, i.e., the product is mixed with water if necessary, filtered, and the ether washed with cold or hot water and dried; or the ether may be treated with a dilute acid before or after a first washing, followed by a second washing, and drying.  Examples describe the production in one and in two operations of an ether from cellulose and ethyl chloride, the ether being soluble in many solvents such as benzol, alcohol, benzol-alcohol mixture, chloroform, chloroform-methyl-alcohol mixture, methyl acetate, and glacial acetic acid and it is stated that the solutions even without filtration, give clear fibre-free flexible films.  Specifications 149,390, [Class 113 (ii), Ships &c., Kinds &c. of], and 200,816 are referred to.
