Title: An improved process for fixing nitrogen
IPC: C01C3/00
Filed: 1926-02-05
Abstract: 250,182. Gewerkschaft Sachsen- Weimar. April 4, 1925, [Convention date]. Addition to 246,177. Void [Published under Sect. 91 of the Acts]. Alkali and alkaline earth cyanides; ammonia.- Cyanides are obtained by the reaction of nitrogen on mixtures of coal with mixtures of alkali or alkaline earth sulphates with one another or with aluminium or magnesium salts with the addition of a catalyst if desired. The reaction mixture may contain crude salts of potash, syngenite, glauberite, kieserite, feldspar, magnesia, or magnesium chloride, sulphate or sulphide, or aluminium sulphide, and instead of the sulphates, sulphides or carbonates or mixtures of them may be employed; or a mixture of say potassium sulphate and calcium carbonate. Other substances mentioned as suitable are rubidium and caesium compounds, lithium carbonate, and a mixture of lithium and sodium sulphates. The reaction may be effected at ordinary, increased, or reduced pressure, and when the cyanization has been effected steam may be passed over the product to obtain ammonia and other nitrogenous products which are absorbed in sulphuric acid to produce ammonium sulphate. The mass after treatment with steam is rendered fit for use again for the production of cyanide, so as to make the process continuous, by passing over it a stream of gas containing carbon, or a current, of coal dust, or by admixing carbon by a mechanical mixing device. By passing over the reaction mass a gas containing carbon, hydrogen, oxygen, and nitrogen, at ordinary raised or reduced pressufre, ammonia is produced. This process may be applied to masses containing alkali-magnesium carbonates or alkaline earth carbonates, or mixtures of these with one another or with catalysts such as iron, nickel, cobalt, manganese or chromium or the process may be applied to the masses described in the parent case.

Title: Improvements in pirn winding machines
IPC: B65H54/14
Filed: 1946-08-06
Abstract: 617,895. Winding yarn. SUTTON, R. Aug. 6, 1946, No. 3701. [Class 120(ii)] In a pirn-winding machine having compensating means for equalising the tension in the yarn during the chases effected by the traverse guide, the compensating means working in synchronism with the traverse guide, yarn from supply Q is led over a pulley R<SP>1</SP>, thence about pulleys S and S' to the thread guide m adjustably oscillated on a pivoted lever by a cam l in a cross shaft L. The pulley S is oscillated with a lever S<SP>2</SP> by a cam l<SP>1</SP> on the shaft L, the pivot S<SP>4</SP> of the lever S<SP>2</SP> being gradually moved, to increase fhe oscillation of the pulley S while the base of the pirn is formed, by contact of the pirn-carrying carriage F with a runner s<SP>6</SP> on the lever S<SP>3</SP> carrying the pivot s<SP>4</SP> of the lever S<SP>2</SP>. When the pirn-base is completed movement of the pivot s<SP>4</SP> ceases. The pirn is held between supports b, b<SP>1</SP>, the support b being driven by a shaft B from a reversible motor D<SP>1</SP> through belt and pulley drives e<SP>1</SP> d<SP>2</SP>, e; e<SP>2</SP>, e<SP>3</SP> b<SP>4</SP> ; and shaft E. The end support b<SP>1</SP> is mounted on an arm B' slidable on a tube C through which extends a rod C<SP>1</SP> the one end of which carries the motor switch contact and the other end a knob c' which can be manually operated to stop or start the motor. The rod C<SP>1</SP> carries a grooved collar engaged by a catch P which holds the motor switch D<SP>2</SP> closed until manually operated or operated by a dagger O on the pirn carriage pressing against a surface p<SP>4</SP> thereon and so open the switch and stop the motor when the pirn has reached the required size. The carriage F is traversed by a screwed rod F<SP>1</SP> with which a half-nut f on an arm f<SP>1</SP> engages, the rod F' receiving its motion from a gear train driven by a cone H contacting frictionally the coned face of the pirn. The gear train is such that whether the pirn is winding in one direction or the other for "S" or "Z" twist yarn, the rod F<SP>1</SP> can be driven in the same direction. The pulley S<SP>1</SP> is carried on an arm s attached to a spring-urged three-armed lever so that if the thread breaks or the supply fails, a brake r' is applied to the pulley R' and a rod p' draws the catch P from the rod C' to open the switch D<SP>2</SP> and stop the motor. A bunch building mechanism is included which operates to stop the normal traverse of the guide m. This mechanism is operated by a cam l<SP>2</SP> on the shaft L which oscillates a lever v<SP>1</SP> to operate a ratchet wheel v<SP>3</SP> having a cutaway portion, so that after a predetermined number of revolutions a lever U, secured to the shaft governing the runner m<SP>4</SP> of the traverse motion, moves to allow the runner m<SP>4</SP> to contact the traverse cam L When this happens, a projection u on the runner shaft trips the ratchet pawl and normal winding ensues.

Title: Improvements in or relating to the separation of mixtures of organic compounds
IPC: C07C29/74
Filed: 1949-02-15
Abstract: One or more components of a mixture of organic compounds, which compounds are substantially water-insoluble compounds containing C, H, and O, wherein the O is present as hydroxyl, carbonyl, carboxyl or ether groups, and which mixture is substantially free from hydrocarbons, is separated by feeding the mixture to an intermediate point of a countercurrent extraction system supplied at one end with a hydrotropic solution and at the other with a liquid hydrocarbon solvent.  Products of the Fischer-Tropsch, Oxo, Synthol and like processes may be separated into alcohols, ketones and ethers. Hydrotropic solutions are aqueous solutions of hydrotropic salts which dissolve compounds not appreciably soluble in water. Separation of extracted compounds from the hydrotropic solution may be effected by dilution with water of which an amount may be added to cause all the organic compounds to distil with it.  The hydrocarbon solution from the extraction may be treated with the same hydrotropic salt under different conditions, with a different salt or with a hydrotropic solution to which inorganic salts, e.g. sodium chloride or sulphate, have been added.  The extract phase also may be subjected to further extraction under different conditions or washed with a hydrocarbon.  General rules for choosing hydrotropic solutions are given.  Suitable salts are alkali salts of C3-C8 alkanoic acids and alkyl sulphonic acids, the latter being preferred for extraction of acidic compounds.  In examples: (1)-(3) mixtures of octanols or of octanol-2 and octanone-2 are extracted with a solution of potassium n-butyrate and with n-hexane; (4) a cut from a Fischer-Tropsch synthesis, freed from acids and carbonyl compounds, is similarly extracted to obtain n-hexanol-1 and 2-methyl hexanol-1.
