Title: Method and plant for the production of slab ingots, billets, plate bars and the like suitable as semifinished material for the production of strip material and/or tubes from metal smelts by continuous casting
IPC: B21B13/20
Filed: 1960-06-20
Abstract: In a continuous casting process, particularly when using rimmed or partly killed steel, the melt is conducted through a degasification chamber under high vacuum shortly before it enters the mould, the melt entering the degasification chamber 3 from the side in a substantially horizontal jet.  Discharge from a tundish 2 is regulated by radio-active means 37, 37a  to maintain a predetermined constant level of metal in the chamber 3.  In the gap between the chamber discharge outlet 8 and the mould 9 which is preferably oscillatable the metal is shielded by an inert gas which may be obtained from gas burners 11.  The issuing casting 13 enters a cooling path 24, driving <PICT:0951199/C3/1> rolls 25, is deflected by a bending roller 26 into a heat-insulating passage 27, passes through straightening rollers 28, a heating furnace 29, a descaling device 30, which may be a hot rolling machine or a water jet device and finally enters a planetary rolling mill 33 followed by smoothing rolls 35.  The degasification chamber may discharge into an intermediate vessel between it and the mould, the discharge being controlled in accordance with the bath level in said vessel. Further the rolling mill may be mounted vertically below the mould and the cooling regulated so that the casting is suitable for rolling without reheat.  Several moulds may be fed simultaneously.

Abstract: Olefins are obtained by dehydrohalogenating halohydrocarbons in fractionating column containing a metal catalyst at 150-500 DEG  C. and continuously recovering the olefin formed by distillation as overhead and separated from hydrogen halide by condensation.  The halohydrocarbon may contain fluorine, chlorine, bromine or iodine or in a paraffin, isoparaffin, cycloparaffin or alkyl aromatic molecule, and may be mixed with hydrocarbon, e.g. as the product of halogenating a hydrocarbon at a molar conversion of up to 50%. The catalyst may be a metal of Group 1a, 2a, 2b, 3a, 5a, 6a, 7a or 8 or alloys thereof particularly iron, steel, copper or nickel. The pressure in the column should preferably be sufficient to ensure that the halohydrocarbons boil above 150 DEG  C.  Alkyl aromatic hydrocarbons are obtained by alkylating aromatic hydrocarbons with products from the above process.  Detergent alkylates particularly are obtained using C8-C30 olefins obtained from n-paraffins by halogenation and dehydro halogenation.

Title: Production of phosphorus
Inventor: LOWE EDWARD JAMES
IPC: C01B25/02
Filed: 1962-06-05
Abstract: <PICT:1004382/C1/1> Elemental phosphorus is produced by reacting at a temperature of from 1020 DEG  to 1500 DEG  C. in a fluidized bed on solid particulate mixture of phosphate ore and an electrically conductive form of carbon, present in such amounts as substantially to surround the particles of phosphate ore, resistance heating being applied by passing an electric current between the electrically conductive particles.  The ore may be any naturally occurring phosphatic material reducible to elemental phosphorus on heating with carbon. The carbon may be present at least in part as a coating on the ore particles.  A liquid high molecular weight hydrocarbon may be used for the carbonization, but preferably a hydrocarbon having not more than 8 carbon atoms in the molecule, e.g. natural gas, is used in a "fluid coking" process, when the hydrocarbon may be added to the fluidized reaction mixture so as partially to replenish the carbon during the reaction.  The process may be batchwise or continuous; a continuous process may utilize a multi-stage fluid bed reactor as in Fig. 2.  21 is a multi-compartment reactor fitted with gas distribution plates 22a-22e carrying solids in beds 23a-23e fed from bin 26. Fluidizing gas heated in one of stoves 28, 29 is fed into the base of unit 21.  Electrical energy is supplied by sets of electrodes 25a, 25b, 25c and 26a, 26b, 26c.  Gas leaving with 21 is freed of solids in cyclone 30 and passes through condensers 32, 33 into which water is sprayed from 34, 35. Condensed phosphorus is withdrawn via valve 36, 37.  Examples are given. Specifications 807,884 and 854,884 are referred to.

Title: Improvements in manufacture and separation of sulphurcontaining splitting products of the acid hydrolysis of keratin and keratin substances
IPC: A23J1/10
Filed: 1931-07-29
Abstract: Sulphur-containing products of the acid hydrolysis of keratin are obtained by treating keratin or keratinous substances such as wool, hair, feathers, hoofs, nails, &c. with mineral or organic acids, stopping the treatment at the point at which the substance treated loses its natural form and becomes a glutinous mass, diluting the mass with water, neutralizing it with ammonia or caustic alkali or alkali carbonates, saturating the solution with ammonium sulphate or magnesium sulphate to complete the precipitation, filtering off the precipitate, and boiling it with water.  Three products are thus obtained, consisting of the part of the precipitate which remains undissolved, and which comprises keratinates, a second part comprising keratoses which separates from the boiling hot filtrate on cooling, and a third part comprising lower hydrolysis products which remains in solution on cooling the filtrate.  Examples are given, in which 40 and 60 per cent sulphuric acid, 24 per cent hydrochloric acid, and 60 per cent formic acid are employed for the hydrolysis, the reactions being carried out in these cases at 80 DEG  C., 60 DEG C., room temperature, and boiling temperature respectively.
