Title: Improved process for producing ethylsulphuric acid
IPC: C07C303/24
Filed: 1924-09-05
Abstract: 221,512. Compagnie de Bethune Soc. Anon. Sept. 7, 1923, [Convention date]. Ethyl hydrogen sulphate; alcohol.-Ethyl hydrogen sulphate is obtained in a continuous manner by absorbing ethylene in hot concentrated sulphuric acid containing a constant proportion of ethyl hydrogen sulphate. The acid mixture, which absorbs ethylene more readily than sulphuric acid alone, should correspond with an ethylene content of 11 to 18 per cent. The ethylene-containing gases are passed by the pipe 3 into an absorber 1, heated by a steam jacket and provided with an agitator 2, the residual gases escaping by the pipe 4. The strength of the acid mixture contained in the absorber is maintained constant by the continual influx of fresh concentrated sulphuric acid through the siphon 5, the resulting mixture of sulphuric acid and ethyl hydrogen sulphate overflowing by the pipe 2<1>. The product is treated in the usual way for the production of alcohol. The Specification as open to inspection under Sect. 91 (3) (a) states that the ethylene-containing gases may be absorbed under pressure, and includes a diagram showing the variation of the rate of ethylene absorption with the increasing content of ethylene in the acid; this subjectmatter does not appear in the Specification as accepted.

Filed: 1929-07-10
Abstract: 336,584. Carreras, R. S. July 10, 1929. Copper, nickel, and cobalt, and their oxides. obtaining.-Ores containing copper, nickel and cobalt are leached with a mixture of dilute sulphuric acid and sodium chloride. The proportion of sodium chloride may be 5 per cent. The insoluble part of the ore, if any, which may contain arsenides and sulphocyanides is oxidized in a furnace and again leached and the solution added to the main bath or treated separately. The liquid, which should be of the concentration 13‹ to 15‹ BÚ., is electrolyzed for recovery of copper in wood vats lined with leads, using thin sheet copper cathodes and anodes of lead or of copper rendered inactive by preliminary treatment with nitric acid or of other metal rendered inactive bv treatment in a bath of an acid solution of a mercury compound. A current density of 0.6 amps. per sq. dcm. at 2 volts is used. The electrolyte is then concentrated by evaporation to a concentration of 28‹ BÚ. and cooled to precipitate alkaline-earth metal and magnesium salts and further concentrated to 38‹ BÚ., and cooled to crystallize out cobalt sulphate. The cobalt sulphate is dissolved to a concentration of 9-10‹ BÚ., and a quarter of its weight of ammonium sulphate and per cent of citric acid are added. The solution is electrolyzed using cathodes of copper-chrome and anodes of graphite or of inoxidizable steel or of other metal which has been rendered inactive. An initial voltage of 2.5 falling to 2, and a current density of 0.66 amps. per sq. dcm. are used. Cobalt is deposited in scales. Nickel is recovered from the remaining electrolyte, which may contain iron, in a similar manner to that employed for cobalt with the exception that in addition to ammonium sulphate, sodium sulphate and a small amount of ammonium carbonate are added to the liquor. Under some conditions the metals may be deposited as oxides.

Title: Elastic fabric and process for the manufacture thereof
IPC: D03D15/56
Filed: 1934-07-20
Abstract: <PICT:0434049/IV/1> <PICT:0434049/IV/2> An impregnable fabric is made by first weaving into a loose textured fabric, Fig. 4, linear elements each made by separately twisting two or more rovings in the same direction until they cannot readily be drawn out, then twisting the rovings together in a direction opposite to their original twist to produce inverse twists as described in Specification 422,960.  The fabric, which may be cotton, is then treated without tension with strong acid or alkali, for example caustic soda 30 DEG  Be., causing the yarns to swell but contract in length and form a close woven and more stretchable fabric, Fig. 6, wherein the yarns are not compressed. The fabric is next impregnated with elastic or plastic material such as rubber or balata by treatment with latex (which may contain vulcanization agents, accelerators, activators, and fillers) or rubber dissolved in a volatile solvent.  After various rinsings and dryings, the fabric is vulcanized.  The fabric may be vulcanized whilst stretched and its elasticity in any particular direction be thus limited.  The fabric may be used for tyres, tyre treads, driving-belts, tarpaulins, clothes, and flexible pipes.  A belt which is elastic longitudinally only may be made by stretching the fabric transversely until its elasticity disappears in this direction, then drying it, assembling a number of such fabrics and pressing and vulcanizing.  In the Specification as open to inspection under Sect. 91 it is stated that the linear elements may comprise slightly twisted rovings of textile products such as sisal.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1426266 Cephradine dihydrate E R SQUIBB & SONS Inc 4 May 1973 [1 June 1972] 21368/73 Heading C2C The novel compound cephradine dihydrate (being the dihydrate of the known cephalosporin compound cephradine, which is 7-(D-α- amino - 1,4 - cyclohexadien - 1 - ylacetamido) desacetoxycephalosporanic acid) is prepared by neutralizing an acid addition salt of base salt of cephradine in aqueous solution or suspension at a temperature of 0 to 25 C. By the word "neutralizing" is meant bringing to the point at which the acid or base moiety of the acid addition or base salt is exactly neutralized by the added base or acid respectively, this point being about pH 5À5 rather than the conventional pH 7 of a strong acid/strong base interaction. The dihydrate, which is isolated by crystallization (preferably after seeding), has a characteristic X-ray diffraction pattern (using a copper K-α radiation source), and differs from known cephradine in its crystalline form, water-solubility and behaviour on vacuum drying at elevated temperature which converts the dihydrate irreversibly into the conventional form of cephradine. The novel cephradine dihydrate may be made up into antibiotically active pharmaceutical compositions with a pharmaceutically acceptable diluent or carrier.

Title: Improvements in or relating to the manufacture of goods containing rubber or similarmaterials
IPC: D06M15/693
Filed: 1932-08-02
Abstract: Reinforced porous or microporous articles of rubber or the like having a high resistance to tear are made by treating a web or webs composed of interlocked fibres with an aqueous dispersion of rubber or the like, effecting coagulation or gelling of the dispersion, and vulcanizing in known manner the coagulated or gelled rubber under such conditions that evaporation of the liquid contained therein is prevented.  Suitable fibres are those of jute, cocoanut, Kapok, cotton, artificial silk residues, asbestos, glass wool and slag wool. Natural or artificial dispersions of rubber, gutta-percha or balata may be employed. Artificial dispersions may include those of coagulated rubber, vulcanized rubber, synthetic rubber, waste or reclaim.  They may be rendered capable of gelling on the application of heat by the addition of sodium or potassium silicofluoride, ammonium persulphate or a mixture of zinc oxide and ammonium sulphate. They may be rendered capable of gelling in the cold in definite and controllable periods by the addition of sodium or potassium silicofluoride in relatively large proportions.  Gelling may also be effected by exposure to gaseous or vaporous coagulants or by spraying with a liquid coagulant.  Wetting agents such as soaps or sulphonated oils may be added to the dispersions.  In an example a web of bleached cotton fibre of low wax content is spread in a tray and sprinkled with a latex mixing of 45 per cent total solids of the following composition, rubber 100 parts, sulphur 40 parts, zinc oxide 2 parts, zinc oleate 3 parts, softener 20 parts.  The mass is lightly kneaded and rolled.  It is lightly sprayed with 10 per cent aqueous acetic acid and then flooded with a similar coagulant.  The coagulated mass is stripped wet from the tray, rinsed, and placed between flat metal sheets and vulcanized under such conditions that evaporation of moisture is prevented.  In another example a mixing of 45 per cent total solids, alkalinity 0.2 per cent expressed in terms of ammonia and of composition, rubber 100 parts, sulphur 25 parts, zinc oxide 2 parts, zinc oleate 3 parts, softener 10 parts, is cooled to 5 DEG  C., and to each 100 gms of the mixing there is added 3 c.c. of a 25 per cent solution of ammonium sulphate.  A fibrous web is saturated with the dispersion and gelled in hot water and subsequently vulcanized without evaporation of the enclosed liquid; alternatively it may be directly vulcanized, gelling taking place during the operation.  Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], are referred to.
