Patent GB-757038-A (GB)
Title: Sulphodicarboxylic acid compounds
Filed: 1954-01-20
Abstract: The invention comprises compounds of the formula <FORM:0757038/IV(a)/1> wherein Me is hydrogen or another cation, R is an aliphatic carbon chain, X is hydrogen or an alkyl group, Y is -CO- or -SO2-radical, R1 is a hydrocarbon radical of 6 to 18 carbon atoms and Z is an alkyl group.  Such compounds are obtained by reacting an unsaturated dicarboxylic anhydride at elevated temperature with an amide of a carboxylic or sulphonic acid having a hydrocarbon radical containing 6 to 18 carbon atoms in a molecular ratio of 1 : 1, esterifying the reaction product with an aliphatic alcohol, and treating the resulting compound with an alkali metal bisulphite or ammonium bisulphite.  Amides mentioned are those of caprylic, lauric and stearic acids and amides of sulphonic acids obtained by sulphochlorinating hydrocarbons having 6 to 18 carbon atoms and reacting the sulphochlorides obtained with ammonia or an alkyl amine. Aliphatic alcohols mentioned are butyl, amyl, hexyl, octyl and 2-ethyl-hexyl alcohols.  The products are wetting agents in alkaline medium.  In examples: (1) maleic acid is reacted with an amide obtained by sulphochlorinating a mixture of aliphatic hydrocarbons having 6 to 18 carbon atoms (boiling point 250 DEG  to 320 DEG  C.) and treatment of the sulphochloride with ammonia.  The product is esterified with 2-ethyl-hexanol in the presence of sulphuric acid and the resulting compound heated with sodium bisulphite and sodium hydroxide solution until water-soluble and the water then evaporated; (2) the amide obtained by sulphochlorinating a mixture of C6 to C18 aliphatic hydrocarbons (boiling point 180 DEG  to 210 DEG  C.) and reacting the product with ammonia is reacted with maleic anhydride, the product is esterified with 2-ethyl-hexanol, and the compound obtained is heated with sodium bisulphite and sodium hydroxide until watersoluble; (3) coconut fatty acid amide and maleic anhydride, the reaction product is heated with octyl alcohol, and the esterified product is refluxed with a solution of sodium bisulphite and sodium hydroxide solution until water-soluble.  Instead of octyl alcohol there may be used alcohols obtained by the reduction of fatty acids containing 4 to 10 carbon atoms, obtained in the distillation of paraffin oxidation products.

Patent GB-404966-A (GB)
Title: Improvements in and relating to the production of bituminous compositions and the like
IPC: C08K5/098
Filed: 1933-01-19
Abstract: A composition for road-making and building purposes is obtained from a bituminous substance normally of insufficient toughness and viscosity, such as coal tar, by adding thereto an aluminium, alkaline-earth metal or rare earth metal soap and stirring until a homogeneous solution is obtained.  A further addition of a drying heavy metal soap, e.g. a cobalt soap, may be made.  Five per cent of an aluminium soap is a suitable addition; this may be reduced by half if a basic soap is used.  Soaps of fatty, waxy, naphthenic or resinous acids may be employed; those of solid acids are preferable. The soaps may be obtained by double decomposition of salts with ordinary alkali metal soaps.  They may be added in a dry or wet state; if wet, the mixture is subsequently heated until the water is evaporated.  Alternatively the soaps may be formed within the bituminous substance by adding separately a suitable carboxylic acid or an ester and an oxide, hydroxide or salt of one of the specified metals; if a salt is employed it should be of an acid which is weaker than the carboxylic acid or is volatile when heated.  In an example 5 parts of pure ground chalk and 7.5 parts of liquid resin obtained from the alkaline waste liquors of paper pulp manufacture are added to 87.5 parts of liquefied coal tar and the mass heated and stirred. Magnesium carbonate or dolomite may be used instead of chalk.

The package may be closed by heat-sealing. The Specification gives examples of oil-based core-binders and of a mould dressing. A number of such soluble packages may be packed in a waterproof container.

Title: Mechanically operated time fuze for artillery ammunition
IPC: F42C9/02
Filed: 1956-01-23
Abstract: 823,771. Ammunition fuzes. DIXI S. A. Jan. 23, 1956 [Feb. 2, 1955], No. 2226/56. Class 9(1) A clockwork projectile fuze has a body 1 on which is rotatably mounted a setting cap 2 rigid with a hollow member 3 housing the clockwork, which has a pinion 4 meshing with a wheel 5 keyed to a frustoconical transmission member 6 rotatable in the member 3 and having guide grooves 6a for balls 7 in its periphery. The balls are arranged to travel along the helical grooves 12 in the member 3 under centrifugal force and so rotate the member 6. Within the body 1 is a primer carrier 9 adapted to slide radially outwards under centrifugal force to hit a striker 10 and locked before firing by a rocking bolt 11 which engages a projection 3a of the member 3 aligned with a notch in a disc 8 mounted on the member 6. On rotating the cap 2 to set the fuze, the member 3. is shifted angularly so releasing the bolt 11, which is then held by the disc 8. On firing the projectile, the clockwork is released and the member 3 is locked to the body 1 by a centrifugally operated bolt (not shown). The balls 7 drive the member 6 which carries the disc 8 shifting the notch 8a out of register with the projection 3a and into register with bolt 11, so that the carrier 9 rocks the bolt out of the locking position into the notch thus releasing the carrier. In a modification, the member 3 flares in the opposite sense and the travel of the balls is reversed. The striker is housed in the frusto-conical transmission member and slides radially outwards under centrifugal force to ignite a primer mounted in the fuze body.

In an air-cored betatron or betatron-synchrotron, the accelerating windings are so proportioned and positioned as to generate magnetic fields which neutralize one another at the electron orbit so that they exert, substantially no deflecting force at the orbit. The accelerate ing windings comprise an inner set C1, C2 and an outer set D1, D2 so designed and positioned as to give cancellation of the field at the orbit and also of its first, and second derivatives with respect to the radius. The guide field is produced by an inner winding H and outer windings G1, G2  so designed that the guide field decreases less rapidly than inversely proportional to the radius. Each winding may be subdivided, the leads emerging at equally-spaced circumferential points, to minimize field variations due to the leads. Specification 622,148 is referred to.
