Title: Improvements in sweetening hydrocarbons
IPC: C10G27/04
Filed: 1963-09-05
Abstract: In the sweetening of light petroleum distillates by conversion of mercaptans to disulphides in the presence of a fixed catalyst bed of inert solid particles coated with a catalyst comprising lead sulphide, the distillate is flowed through said bed in the presence of sufficient oxygen to convert the mercaptans to disulphides, and in the presence of a solution of sodium sulphide which contacts the particles of the bed such that the coatings are maintained as lead sulphide, and sweetened distillate is continuously withdrawn from the bed.  The distillate and sodium sulphide solutions may be mixed and passed through the bed together, or the distillate and sodium sulphide solution may pass through the bed in counterflow, in which event a little elemental sulphur may be added to the sour distillate. A small amount of caustic may also be present in the system, preferably added via the sodium sulphide solution.  The sweeten distillate may be water washed.

Patent GB-796867-A (GB)
Title: Improvements in and relating to polymerisation products
Inventor: PETER MAURICE JACQUES KOCH DE
IPC: C08F2/00
Filed: 1953-12-17
Abstract: Mixtures of polymerizable materials, at least one of which when fully polymerized forms a thermoplastic resin and another of which is diethylene glycol bis (allyl carbonate), are polymerized to form sheets or blocks which are sufficiently rigid and stable to be handled and worked but which are still sufficiently thermoplastic to be shaped under heat and pressure and can be converted to infusible fully polymerized substances.  Specified thermoplastic resin-forming materials are methyl and higher alkyl methacrylates, methacrylic acid, acrylonitrile, styrene, vinyl acetate and allyl acetate.  The mixtures may contain other materials which yield thermoset resins, e.g. triallyl cyanurate and methacrylic anhydride, and optionally fibres, fillers and pigments.  Peroxy catalysts, e.g. benzoyl peroxide, and, where polymerization to the infusible state in the presence of ultra-violet light is contemplated, benzoin-type catalysts may be added.  Preferably some physical property, e.g. power factor or refractive index, of the ideal intermediate material is measured and subsequent mixtures polymerized to give the corresponding value.  Polymerization to the infusible state may be effected by highenergy radiation, e.g. by exposing to a cobalt 60 source. Partial prepolymerization of the thermoplastic resin-forming monomers or the thermoset resin-forming monomers may be effected. In examples the copolymerization of ethylene glycol bis-(allyl carbonate) with (II, IV and V) triallyl cyanurate and methyl methacrylate and (III) triallyl cyanurate, methyl methacrylate and n-butyl methacrylate is described.  Specification 738,487 is referred to.

Title: Improved process for the finishing of cellulosic textile materials
Filed: 1938-12-07
Abstract: 526,098. Treating textiles with liquids. CALICO PRINTERS' ASSOCIATION, Ltd., LANTZ, L. A., and MILLER, W. S. Dec. 7, 1938, No. 35661. [Class 15 (ii)] Cellulosic textile yarns or fabrics are rendered resistant to shrinkage on washing and extension when damp without at the same time becoming resistant to creasing, by impregnating them with so much of a solution of formaldehyde and an acid at a pH value of not more than 2 that after drying the material so as to cause a reaction between the cellulose and formaldehyde there is fixed on the treated material, after washing and drying, not less than 0.5 per cent. and not more than 1.75 per cent. of formaldehyde in the case of regenerated cellulose and not less than 0.1 per cent. and not more than 0.4 per cent. formaldehyde in the case of natural cellulose fibres, the material during the drying operation being kept at or slightly over the final dimensions until completely dry. Treatments in which embossing, glazing or similar mechanical treatment is effected subsequent to impregnation but before the heat treatment, or in which the impregnation is carried out for a period of two hours or more, are excluded. The concentration of formaldehyde may be 15 per cent. or less. The acid used may be sulphuric, nitric, phosphoric, phosphorous, pyrophosphoric, hydroxymethane sulphonic, trichloroacetic, oxalic, maleic, malonic, chloracetic, tartaric, or citric acid. Instead of the free acid a substance which liberates acids on heating or by reaction with the formaldehyde, e.g. cyclohexylamine perchlorate, may be used. The temperature of drying may be 60-130‹C. Unfixed formaldehyde is removed by washing in weakly alkaline solution. In examples viscose crepe fabric is treated with a solution containing 5-15 per cent. of formaldehyde and 2.5 per cent. of tartaric acid or 2 per cent. of phosphoric acid, or 1 per cent. of nitric acid, and squeezed till 108 per cent. of solution remains in the cloth. Drying is effected at 70-110‹C. for a few minutes. In another example, cotton fabric is impregnated with a solution containing 3 per cent. of formaldehyde and 0.13 per cent. of sulphuric acid, squeezed until 70 per cent. of solution remains in the cloth and dried at 105‹C. Specifications 452,150 and 477,084 are referred to.

Abstract: 343,576. Alternating-current commutator and induction machines. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT, 75, Boulevard Haussmann, Paris. Nov. 22, 1929, No. 35799. Convention date, Nov. 29, 1928. [Class 35.] An automatic starting arrangement for a compen sated induction machine comprises resistance b and inductance a in parallel in serted in the secondary circuit; the machine is of the type having a compensatoring commutator winding on the primary member or rotor R connected through bushes to the secondary or statoi winding S, or it may con. sist of an induction machine cascaded with a frequenc} changer, the no-load speec being regulated so that the maximum torque corresponds substantially to the synchronous speed. The compensating voltage is so chosen that at no-load the machine or group operates as a motor at a speed slightly above synchronism and as a generator below synchronism. The resistance may be dispensed with by constructing the magnetic circuit of the inductance of solid metal in which eddy currents are induced. The invention is applicable to the regenerative control of motors, the compensating voltage being selected and its phase regulated by moving the brushes so that the no-load speed is slightly lower than the synchronous and the maximum generator torque corresponds to synchronism. If the resistance be arranged in two or more steps for motor operation, the whole or a part may be used in parallel with the inductance for regenerative braking. In order to avoid the necessity of moving the brushes when changing over to regenerative operation, the leads from the brushes may be connected to the opposite ends of the secondary winding or of the group formed by the secondary winding and the starter. Specification 223,657, [Class 35, Dynamo-electric generators &c.], is referred to. According to the Specification as open to inspection under Sect. 91 (3) (a) the resistance may be dispensed with in the case of asynchronous generators. This subject-matter does not appear in the Specification as accepted.
