IPC: C01B21/20
Filed: 1920-09-23
Abstract: 166,095. L'Azote Franþaise Soc. Anon. July 5, 1920, [Convention date]. Addition to 149,304. Void [Published under Sect. 91 of the Act]. Nitrogen oxides are absorbed from dry gaseous mixtures by substances other than alumina which are capable of forming addition products at temperatures between 0‹ C. and 80‹ C. and of liberating the nitrogen oxides again at a higher temperature, generally about 100‹ C. The substances mentioned as suitable are ferric chloride, calcium, magnesium, copper, zinc, and iron oxides, and certain aluminous products, such as dehydrated bauxite. The essential condition to be observed in order that these substances may absorb the nitrogen oxides is that the substances are obtained or dehydrated at low temperature. The heating to liberate the nitrogen oxides may be effected in a partial vacuum.

Abstract: 603,359. Flexible rulers. DAVIDSON, A. D. Oct. 18, 1945, No. 27402. [Class 97 (iii)] The rule 3 is bent to the desired plane curve by the application of a compressive force to the ends of the rule and of torques at one or more points. of the rule, these forces being applied by mechanisms, e.g. worm-gearing, which itself holds the rule 3 in the set position. As shown, the angle between the pivotally interconnected arms 1, 2 of the V-shaped frame across the mouth of which the flexible and resilient rule extends, is varied by rotating rod 16 whose ends are provided with screws of opposite hands which engage with corresponding screw-threaded elements 17, 18 on the arms to apply a compressive force to the rule. Torques are applied at the ends of the rule by means of worm-wheel mechanisms 12, 13 operated by knobs 10, 11. The rule may be constrained at any point along its length by stop 31 carried by bar 30 slidable in an aperture in the pivot of arms 1, 2. Stop 31 can be axially adjusted in terminal block 46 so as to be brought into contact with the inner or outer surface of the rule or with its edge. A slidable cross-head 32 secured to bar 30 by set-screw 43 is pivoted to rods 33 and 34 which pass through, and are clamped at 44, 45 to sleeves 35, 36 carried by arms 1, 2 and are adjustable in relation thereto by screw means operated by wheels 41, 42. Rule 3 has a reflecting surface whereby any suitable optical means may be used to determine the radius of curvature or tangent to the curve at any point thereof. Locating members 28, 29, are slidably disposed in adjustable pillars 24, 25, and terminate in steel points which on pressing down serve to locate the instrument. Small and large wheels 19, 20 are provided on the ends of the rod 16 for making coarse and fine adjustments. Scales and indicating marks as shown are provided for all the adjustable elements 1, 2, 12, 13 and 30.

Title: Improvements relating to the production of condensation products
IPC: C08C19/12
Filed: 1951-11-27
Abstract: Condensation products which may be used as anion exchangers are obtained by heating a mixture of pyridine or pyridine bases with chlorinated rubber at a temperature between 40 and 90 DEG C. and then submitting the reaction product to a further heat treatment above 90 DEG C. for a time sufficient to split off all the chlorine present, finally grinding the product and washing it with a strong alkali solution.  The pyridine bases which include picolines and lutidines and also the product obtained by distilling a fraction of raw tar oil at a temperature of 110-170 DEG C., may be used in a ratio of 2-4 parts per part of chlorinated rubber which preferably has a chlorine content of 62-68 per cent.

Title: A process for the production of vinylchloride polymers and copolymers
IPC: C08F14/06
Filed: 1965-06-30
Abstract: Stereoregular vinyl chloride polymers are prepared by a process which comprises carrying out the polymerization at - 60 DEG  to 0 DEG  C. using a catalyst conventionally employed at said temperatures while subjecting the monomer to a grinding or shearing action greater than that caused by a conventional stirring action.  The vinyl chloride may be copolymerized with vinyl acetate, propionate or stearate, or with methyl, ethyl or iso-octyl acrylate.  The process may be effected using a ball or rod mill, band mixer or planetary stirrer, and the products may be after-chlorinated.  In examples (1) vinyl chloride and (5) vinyl chloride and vinyl acetate are polymerized in a ball mill at - 12 DEG  C. in the presence of methanol, carbon tetrachloride, hydrogen peroxide, ferric sulphate and ascorbic acid; and the product of (1) is chlorinated in a hydrochloric acid/chloroform medium in the presence of ultraviolet light.  In comparative examples vinyl chloride is polymerized at - 12 DEG  C. in aqueous media in the presence of (2) methanol, carbon tetrachloride, emulsifier, hydrogen peroxide, ferric sulphate and ascorbic acid and (3) glycerine, gelatine, methylhexene, di-t.-butyl peroxide, nickelous sulphate and ultraviolet light; and at +60 DEG  C. in aqueous suspension.

Title: Improvements in the manufacture and production of stable suspensions
IPC: C01G1/04
Filed: 1930-09-18
Abstract: In the manufacture of metal carbonyls, stable suspensions of solid materials capable of forming the carbonyls, such as the free metals, or products containing the same, or compounds of the metals, such as the oxides or carbonates, which by reduction can be brought into a form capable of reaction with carbon monoxide, are prepared by using as the liquid vehicle at least two immiscible liquids which do not dissolve the solid material. Liquid metal carbonyls mixed with water or aqueous solutions of acids, bases or salts may be used.  The solid may be made into a paste with about its own weight of carbonyl, water then being stirred in, generally in an amount ranging between 1 and 20 per cent, preferably about 10 per cent, by weight of the solid. Instead of water, glycerine or aqueous suspensions of jelly-like masses such as aluminium or iron hydroxides may be used.  These latter may be prepared by treating metalliferous residues from the production of metal carbonyls with acid, filtering the solution, and adding ammonia.  Hydrocarbons such as gasoline may replace the metal carbonyls in the above mixtures.  More than two liquids, for example water, metal carbonyl, and a high boiling hydrocarbon oil, may be used.  Examples describe the preparation of stable suspensions of reduced roasted pyrites and nickel powder.

Abstract: 937,278. Control of D.C. motors. ROLLS-ROYCE Ltd. July 20, 1962, No. 28112/62. Class 38 (3). When switch 44 for controlling a reversible motor is moved to the open position, relay coil 41 is de-energized so that switch 40 is positioned to complete a circuit from power-lead 18 through limit switch 16, field winding 11, brake coil 15 and armature 10 to return-lead 23. The motor drives a valve member to a closed position, wherein limit switch 16 is opened to stop the motor. If switch 44 is now closed, relay coil 41 is energized to move switch 40 to its alternative position. The motor circuit now includes field winding 12, power-lead 19 and return-lead 22 so that the motor drives the valve towards the open position until limit switch 17 opens. Each limit switch is maintained closed except when the motor is at the respective end of its travel. The valve may be a shut-off cock in a high pressure fuel line forming part of a gas turbine fuel arrangement. The system shown prevents accidental operation of the valve if a stray voltage is applied across a field winding.
