Title: An improved process for the manufacture and production of the nitrogen-hydrogen mixture in the synthetic production of ammonia
IPC: C01B3/02
Filed: 1920-06-15
Abstract: A mixture of nitrogen and hydrogen for use in the synthetic production of ammonia is prepared by subjecting to catalytic decomposition with water-vapour, a gas containing nitrogen, carbon monoxide, and preferably hydrogen, in such proportions that on subsequent removal of carbon dioxide and impurities a gas-mixture of the composition required for the production of ammonia, is obtained. The original gas-mixture may be prepared by mixing water-gas with a gas such as Dawson gas; or it may be prepared in a water-gas producer by introducing air with the water-vapour, in which case the heating periods may be less frequent, particularly if the air and/or water-vapour is preheated, for example by the gases leaving the generator, or they may be entirely dispensed with.  The catalytic transformation of the carbon monoxide in the mixed gas so obtained is conveniently effected by the processes described in Specifications 27955/12, 8864/13, 27963/13, and 16494/14; and the resulting gases may be freed from carbon dioxide by washing with water under a pressure of 10 atmospheres or more, and from traces of carbon monoxide by washing with cuprous solutions.  Specifications 12608/88, 2720/08, 26770/12, and 27117/12 are also referred to.
Patent GB-1321006-A (GB)
Title: Rotary printing press
Inventor: WEISGERBER WILLI
IPC: B41F13/14
Filed: 1971-05-21
Abstract: 1321006 Printing apparatus MILLER PRINTING MACHINERY CO 21 May 1971 [22 May 1970] 16324/71 Heading B6C A plate cylinder 10 is mounted such that on axial adjustment the circumferential register is maintained. For this purpose the helical drive gear 34 for the plate cylinder shaft 12 is mounted on that shaft by means of a ring 30 affixed to the gear and a hub 18 affixed to the shaft. The hub and the ring have aligned slotted portions 22 and 32. The slot 22 houses a spline 106 carried on an axially movable adjusting member 80 and the slot 32 houses a key member 116 having a portion 118 slidably co-operating with a slot 110 in the spline. The portion 118 and the slot 110 are set at an angle to the axis 12, which angle corresponds to the helix angle of gear 34. Thus, axial movement of shaft 12 and plate cylinder bearings 16 (by means of worm 144 and worm surface 138 in collar 136), causes gear 34 to be circumferentially displaced relative to shaft 12 to maintain circumferential register. When circumferential adjustment is required a wheel 60 is rotated to cause axial displacement of sleeve 58 and thus of member 80. Axial displacement of member 80 moves spline 106 in slot 22 and thus rotates the gear 34 relative to shaft 12. For coarse circumferential adjustment an adjusting gear 42 secured to hub 18 is used to rotate the hub relative to gear 34. For this purpose an adjusting wrench 46 having a geared socket head portion 48 is placed on a bolt 52 fixed to gear 34 such that its geared surface 50 mates with gear 42. Clamps 128 and 148 are provided for locking the plate cylinder in the adjusted position.

Title: Improvements in or relating to synthetic linear soluble polymers and copolymers comprising a major proportion of carboxylic acid amide linkages
IPC: C08G69/26
Filed: 1954-06-04
Abstract: Linear polymers and copolymers which are soluble and have melting-points above 275 DEG  C., many having melting-points appreciably above 300 DEG  C., or being infusible, contain a major proportion of units containing an amide link and derived from a carbocyclic dicarboxylic acid and piperazine or a substituted piperazine.  The remaining units may be derived from other acids, diamines, dihydric phenols, disulphonic acids, bis-halogen formates of glycols and diisocyanates.  Preferably not more than six different types of residues are present in the copolymers. The Specification lists a large number of starting materials, including carbocyclic acids containing two rings separated by hetero atoms such as sulphur, oxygen, phosphorus and silicon, and a large number of combinations of starting materials.  The polymers and copolymers are in general soluble in such solvents as chloroform/methanol, methylene chloride/methanol, chloroform/formic acid, pentachloroethane/phenol, ethylene chlorohydrin, 1,1,2 - trichloroethane, acetic acid, dimethyl formamide, chloroform, lactonitrile, trichloroethane/acetic acid, ethanol/nitromethane and 80 per cent ethanol.  The polymers may be prepared by polymerization in the presence of a solvent, preferably high-boiling, such as phenol, hydroxydiphenyl, dinaphthol and p-toluene sulphonethylamide, the solvent finally being removed, if required, by washing.  The reaction may thus be carried out in the liquid phase up to the high polymer stage. Preferably, however, the polymers are obtained by a lowtemperature interfacial condensation, the reactants, in separate phases, e.g. in an emulsion, reacting at the interface, in at least one phase the reactants being in a diluent and the acid reactant being in the form of an acid halide. Preferably the reactants are liquid but one may be a solid, suspended in a diluent in which the reactant is partially soluble.  The heterogeneous reaction system may be aqueous or non-aqueous. Emulsifying agents and acid acceptors may be present. Non-reactive solutes may be present to improve the product or the yield.  The reaction is preferably performed at temperatures between - 10 DEG and 60 DEG  C.  The reactants may be relatively impure. The final polymers may be stabilized by reaction with a monofunctional compound or such a compound may be included with the initial reactants.  The polymers may be wet- or dry-spun from solution, or used to form films.  Solutions in the concentration range of 5-50 per cent may also be employed for dipping, extruding, calendering, casting or other moulding technique. Eightyeight examples are given.

Title: Improvements relating to the distillation of materials containing hydrocarbons
IPC: C10G1/04
Filed: 1930-05-30
Abstract: Hydrocarbon distillates are obtained by distilling a mixture of finely-divided carbonaceous material, e.g. coal, anthracite, lignite, peat pitches, asphalts, bagasse, sugar beet waste, sawdust, &c. with a mineral oil having a low initial boiling point of about 200 DEG  C. and a wide distilling range with an end point of about 400 DEG  C., the distillation being carried out through this range at substantially atmospheric pressure so that the volatile constituents of the oil and the carbonaceous material are carried off together throughout the distillation.  The amount of oil used is equal to or greater in weight than that of the coal and is such that no destructive distillation of the coal takes place.  The distillation may be continued until a solid residue is obtained free from asphalt, pitch, or tar, or it may be discontinued to leave a fluid residue. Cracking of the distillate may be obtained by adding a catalyst e.g. a sodium soap to the mixture or the alkaline clays, oxides of iron, &c. in the coal may act catalytically.  Alternatively, the sodium soap may be produced in situ by pre-oxidizing the coal by treatment with water and ozone and then adding the oil.  Equal quantities of oil (preferably Persian fuel oil of ,895 sp. gr.) and ground coal are mixed in a tank provided with a high speed stirrer and then conveyed to a still.  The latter is heated to 290 DEG  C. whereupon the fire is withdrawn and air passed through the mixture.  The reaction then proceeds exothermically the temperature being regulated so as not to exceed 400 DEG  C.  The devolatilized coal is withdrawn p intermittently and replaced by fresh mixture.  The distillate obtained is then cracked.

Title: Process for the treatment of solid materials in electrolytes
IPC: C25C1/08
Filed: 1943-10-13
Abstract: 577,568. Electrolysis. REDDIE, L. N. (Union Miniere du Haut-Katanga). Oct. 13, 1943, No. 16831. [Class 41] In a process for recovering non-ferrous metals such as cobalt and nickel from their oxides or oxygen-containing radicles, an acid solution containing the metal and the oxidematerial in finely-divided state, is electrolysed in a diaphragmless cell having an insoluble anode, and the rate of delivery of the material to the solution is regulated to maintain the pH constant between the limits 4À5 to 6. By the process, materials which are not normally soluble in the acid solution, are broken down by the liberated anode products and so the metal passes into solution and can be electrodeposited. In one application pulp reject from an oxidized copper ore leaching plant, and containing gangues and sulphate solutions, was electrolysed, together with a concentrate containing malachite. Another application is to the electrolysis of cobalt-hydroxide (or carbonate) derived by adding milk of lime to cobalt sulphate derived from the cobalt-ores by extraction with sulphuric acid, copper and other impurities being mainly removed prior to the lime-treatment. In this process, manganese impurities are removed from the electrolysis by di-oxidation by anodic products. Any cobalt hydroxide remaining in the pulp after electrolysis can be re-treated with acid, concentrated, and used to pulp the precipitates being fed. A further application is in the reduction of higher natural oxides of such metals as cobalt, manganese, and nickel,by nascent hydrogen or ferrous sulphate, the reduced oxide being then soluble in acid, and the ferric sulphate being again reduced to ferrous at the cathode. By this process, cobalt oxides may be treated in the above-described copper-electrolysis and converted into sulphates. Acid from pipe 12 and of pH 4.5 to 6, and finelydivided solids from a hopper 10, are mixed by agitation in a tank 11, and delivered to a supply tank 17 from which the surplus is returned to tank 11 by way of a pipe 18. The suspension is passed at a uniform controlled rate from tank 17 to the cell, and agitated by being air driven by a blower 34 and hose 32 through vertical bores in each anode 25, and outlets 50, Fig. 2. Excess of liquid and undeposited solids is withdrawn by pipe 36 to a separator tank 37 from which acid is withdrawn through pipe 38 to a concentrator 47 for re-use, whereas the solids are pumped into a pressure-tank 40 and thence to a filter-press 44, from which the acid is withdrawn and passed through pipe 45 to the concentrator 47 for re-use. The filter-press may be cleaned periodically, or be a continuous rotary one. A clean cathode may replace one withdrawn for stripping.
