Title: Improvements in or relating to acrylonitrile ternary polymers
IPC: C08F220/44
Filed: 1954-05-12
Abstract: Terpolymers are made by polymerizing a mixture consisting of from 2 to 15 per cent of acrylamide or methacrylamide, from 1.5 to 15 per cent of at least one methyl or ethyl vinyl pyridine, and the remainder acrylonitrile.  Polymerization may be carried out batchwise or continuously in bulk, in solution in solvents such as benzene, toluene or xylene, or, preferably, in water, with the assistance of heat and/or light and/or catalysts such as ethyl, propyl, butyl, tert.-butyl, tert.-amyl, lauryl, oleyl, and stearyl peroxides, tert.-butyl and tert.-amyl hydroperoxides, acetyl, propionyl, lauroyl, stearoyl, malonyl, succinyl, phthaloyl, benzoyl, acetyl benzoyl, and propionyl benzoyl peroxides, coconut oil peroxides, ascaridole, azodiisobutyronitrile, and the salts of inorganic per-acids, such as the ammonium and alkali metal salts of percarbonic, peracetic, perboric, persulphuric, perphosphoric and perchloric acids which may be used alone or in a redox system consisting of one of the above salts or sodium chlorate, an activator such as ferrous sulphate or ferric ammonium, ferric potassium, or ferric sodium sulphate, and an oxygen containing sulphur compound capable of undergoing oxidation such as alkali metal sulphites, bisulphites, hydrosulphites and thiosulphates, sulphurous acid, alkyl sulphites, p-toluene sulphinic acid, and formamidine sulphinic acid. In aqueous media the reaction is preferably carried out at a pH of less than 6, and in batchwise polymerization the catalyst may be added gradually as polymerization proceeds.  In one method of polymerization the reaction vessel is first charged with an aqueous slurry of a previously prepared acrylonitrile polymer which may be the same as or different from the copolymer to be prepared, e.g. polyacrylonitrile or an acrylonitrile/methyl acrylate copolymer.  The terpolymers may be used in the preparation of dyeable films and oriented fibres, and in moulding, adhesive, and coating applications; in the latter case the terpolymer may be formed in situ by applying the monomeric material to the base to be coated and then polymerizing. Specifications 427,494, 586,881 and 670,268 are referred to.

Title: Improvements in and relating to polyethylene glycol compositions
IPC: C09J189/00
Filed: 1944-07-19
Abstract: A solid composition having a substantially uniform rate of solution in water is prepared by dissolving tartaric acid in a molten polyethylene glycol having an average molecular weight of at least 4000, cooling the solution to about 50 DEG  C. and mixing therewith at least two mols. of sodium bicarbonate per mol. of tartaric acid. The rate of solution of the polyethylene glycol will depend on the proportion of the added ingredients which may be 10-90 per cent of the weight of the composition.  Preferably, the proportion is 40-60 per cent and final variations in the solubility rate of the composition are effected by selecting the molecular weight of the polyethylene glycol employed.  The compositions may be employed as temporary seals which are broken after contact with water for a predetermined time, as soluble binders for pellets containing pigments, bath salts or similar materials, or as temporary formers for wire coils (see Group XXXV).

Abstract: 642,664. Riveting. AVIATION DEVELOPMENTS, Ltd., and SPRINGATE, M. S. May 23, 1947, No. 13908. [Class 43] A feeding device of the magazine type for rivets and the like, and particularly for use in blind riveting, includes two or more elongated jaws spring-urged lengthwise and shaped externally intermediate their ends to co-operate with the forward end of the jaw housing, the co-operating parts being so shaped that said jaws are normally held in the closed position, but can be carried forward by the leading rivet as the latter is advanced, into positions in which they are free to open. Two jaws 1, 2, with internal lips 3 at their outer ends and an external flange 5 at their inner ends, have intermediate external projections 4 which taper towards the inner ends of the jaws. The jaws. which present between them a cylindrical passage 7 for the rivets, are fitted in a housing 12 which is secured to the barrel 13 of a riveting tool, and which has at its outer end an internal flange 14 tapered at 15 to co-operate with the projections 4. One end of a compression spring 16 abuts against the internal flange 14 of the housing 12, the other end abutting against the external flange 5 of the jaws, so that the jaws are urged into the housing into positions in which the tapering parts 4, 15 co-act to prevent said jaws opening. In operation when the leading rivet 8 is advanced tail first along a mandrel 19, its head engages the inclined surfaces of the lips 3 and moves the jaws axially against the action of the spring 16 until the co-operating parts 4, 15 reach positions in which they allow the jaws to open; when the rivet 8 has passed right through the jaws the latter are returned by the spring 16 to their closed positions, and the front face 17 of the jaws acts as an anvil. The jaws may be curved for operation in places difficult of access.

Title: Process of refining petroleum and like hydrocarbons
IPC: C10G67/00
Filed: 1929-05-07
Abstract: 338,483. Triggs, W. W., (Pan American Petroleum Co.). May 7, 1929. Mineral oils, purifying.-A process for purifying hydrocarbon oils, consists in treating the oil, below 32‹ F., with liquid sulphur dioxide in a single treating tower, and after separating the two liquids, treating the separated oil containing dissolved sulphur dioxide preferably at a low temperature with sulphuric acid and thereafter separating the purified oil from the acid residues. Oils such as petroleum, lubricating, spray or mineral medicinal oils are thereby freed from unsaturated, aromatic and sulphur-bearing hydrocarbons. Oil passes from a tank 1, through a tubular heat-exchanger 8, where it is cooled to about 17‹ F. by treated oil coming from the single treating tower 9 through a spray 13. The cooled oil is discharged through a tube 7 having a meter 101, and enters the bottom of the tower 9 and rises through packing material 10 to meet a descending stream of cooled liquid sulphur dioxide from a spray 73. The oil containing sulphur dioxide is passed into a tower 31 where it is mixed with sulphuric acid which enters through a tube 33, and is discharged through a pipe 34 into a settling tank 35. The sludge formed in the tank 35 is drawn off through a pipe 37 into a tank 38, and the purified oil is pumped through a pipe 42 into a tank 43, and may be submitted to treatment with alkalies or distilled. The sulphur dioxide containing extracted hydrocarbons formed in the tower 9 is drawn off through a pipe 45 and passed, through a spray 46 in the heat exchanger 47. Whereby the sulphur dioxide, supplied to the tower 9 from a tank 67, is cooled. The extract is discharged from the heat exchanger 47 through a pipe 52 to an evap-- orator 56 where sulphur dioxide is removed byfalling on tilted trays 53 heated by pipes 54, andthereafter through a second evaporator 60 where. a similar treatment is effected. The residue of unsaturated and aromatic hydrocarbons is discharged through a cooling coil 65 to a tank 66. The sulphur dioxide liberated in the evaporators- 56 and 60 is compressed and passed through cooling coils 91 and 99 connected to the tank 67. Specifications 338,482 and 338,484 are referred' to.
