Title: Improvements in or relating to the production of carbon black
IPC: C09C1/50
Filed: 1946-11-19
Abstract: An improvement in the process for producing carbon black of the type described in Specification 621,031 comprises the provision of a combustion chamber and intermediate chamber wherein the reactant hydrocarbon, before entering the reaction chamber, is preheated by burning a combustible mixture in direct heat-exchange <PICT:0627872/III/1> therewith.  Hydrocarbon is continuously sprayed, or in the case of liquid such as gas oil pumped at say 100-150 pounds per square inch, through inlet 53, with or without added air, into cylindrical preheating combustion chamber 52 having refractory lining of e.g. sillimanite or alpha-alumina 51 and one or more burners, as shown tangential burners, 55, for fuel gas and air to effect direct heat-exchange at above, say, 3000 DEG  F.  The flame and combustion products spiral towards the centre of the combustion chamber 52 and are carried with the preheated hydrocarbon feed into cylindrical intermediate chamber 34 of smaller diameter having refractory lining 35, wherein a layer of combustion products flows helically next to the chamber wall insulating the axially flowing hydrocarbon therefrom, while continuing preheating and vaporizing and/or pre-cracking of the feed.  The resultant gaseous mixture passes to the reaction chamber 10 which is of the type described in Specification 621,031 without a separate preheater.  The whole apparatus is enclosed in a steel sheel 13 with insulation 12.  The effluent from reaction chamber 10 is cooled to 1200 DEG  F. in an air-cooling pipe and then to 300-400 DEG  F. by water spray before separating the carbon black in bag filters.

Title: Method of introducing substances of low melting point into hollow bodies, such as the valve stems of internal combustion engines for heat conducting purposes
IPC: F01L3/14
Filed: 1932-12-03
Abstract: 407,473. Valves. ASPLEY, E., 128, Grange Road, Alvaston, Derby. Dec. 3, 1932, No. 34316. [Class 7 (vi).] In a method of introducing substances of low melting-point into hollow bodies, for example metallic sodium, common salt, &c. into the hollow stems of poppet valves of internal-combustion engines, the displacement of the air contained within the hollow body is effected by the insertion and withdrawal of a rod or the like, instead of withdrawing the air by an inserted pipe as described in Specification 380,571. The Figure shows the hollow valve a, to the open end of which is loosely fitted a funnel c. The required amount of sodium is placed in the funnel and melted. A rod f is then slowly inserted and afterwards withdrawn suddenly, thereby creating a suction which causes some of the melted sodium to enter the hollow stem. The operation is then repeated until the required amount of sodium has been introduced.

Title: Improvements in or relating to processes for de-sizing
IPC: C12N9/96
Filed: 1934-11-29
Abstract: Goods sized with starch are de-sized with an enzyme and a high molecular nitrogenous compound of a basic nature or salts thereof, containing at least 8 carbon atoms, if desired, together with activators, stabilizers, and substances exerting a buffer action. The nitrogenous compound is preferably an aliphatic amine containing at least eight carbon atoms, e.g. dodecylamine or oleylamine, or higher amines of the hydro-aromatic or cyclo-paraffin series or salts thereof.  The nitrogenous compound may be substituted by alkyl, oxyalkyl, oxy, alkoxy, or amino groups, halogens, or it may be in the form of quaternary salts.  A proportion of one part of the nitrogenous compound to 2,000--20,000 parts of the de-sizing bath is preferred.  In an example, cotton sized with starch is de-sized with a solution containing sodium chloride, dodecylamine hydrochloride and pancreas amylase at 45 DEG  C., the pH value of the solution being adjusted to 6,7; the di-sizing bath remains stable even after prolonged use.  In a further example, de-sizing is effected with a bath at 50 DEG  C. and 5 pH, containing condensed malt extract and abietinyl-dimethylbenzyl-ammonium chloride.  In other examples, substances used are abietinyl amine, and the mixture of amines obtained by converting the mixture of aliphatic acids from palm kernel oil into nitriles and reducing to amines.

K-O., 38, St. Mary's Road, Ashton-on-Mersey, both in Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Dec. 5, 1932, No. 34470. [Class 38 (iii).] Brake devices.-In a traction system adapted for progressive operation automatically under control of a current limit switch, the final operation of the limit switch, when regenerative operation of the motor ceases to be useful, establishes or permits the application of a power brake. Movement of a pedal 6 from an " off " position, in turn closes the exhaust from a brake cylinder 1, establishes motor connections for regenerative braking, simultaneously varies the setting of the current limit relay, and the opening of a valve connecting the air reservoir 4 through a valve 7, to the brake cylinder 1, and finally connects the brake cylinder 1 to the air supply through a byepass 9. The valve 7 is opened by the energization of a coil 8, upon final operation of the current limit switch, and the power brake is applied at a rate determined by the position of the pedal 6 in its third range of movement. The motor circuit is opened with the application of the power brake. Specifications 411,482 and 411,541 are referred to.

Abstract: 958,684. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 5, 1961 [Oct. 10, 1960], No. 34657/60. Heading G6C. The sheath 2 enclosing the fuel member 1 of a nuclear fuel element is provided with helical heat transfer fins 3 and longitudinal splitter fins 4, the latter possessing axial and radial asymmetry so that, when coolant gas flows lengthwise of the element, lateral stabilising forces are applied to the element. In the example illustrated, there are four equi-spaced longitudinal splitter fins 4, one being of simple fin form, one having an L-section outer region 8 for one-third of its length from the top with the remainder of simple fin form, one having an L-section outer region 9 for one-sixth of its length from the top with the remainder of simple fin form, and one having an L-section outer region 10 for one-ninth of its length from the bottom with the remainder of simple fin form. With such an arrangement, the horizontal force R at the top of the element was found to be approximately seven times greater than the horizontal force r at the bottom. Instead of L-sections on the splitter fins 4, T-sections could be used and the simple fin form parts could have a castellated profile (as shown by the broken lines 13). The fuel element is shown vertically orientated in a nuclear reactor core channel 11 defined by the wall 12.

Abstract: 1,015,521. Condenser systems ; removal of water-vapour from gases. PHILIPS GLOEILAMPEN FABRIEKEN N.V. Sept. 17, 1962 1962 (Sept. 20, 1961], No. 35313/62. Heading BIB. [Also in Division F4] A gas mixture is cooled in order to separate a component in a solid state in a device comprising cooling members arranged between, and in heat-conductive relationship with, two spaced layers of gas-permeable material, wherein the gas mixture flows partly through one layer and partly through the other layer into the space between the two layers. In the case of a gas mixture which contains water-vapour, snow is deposited on both layers of gaspermeable material. As shown, a gas mixture to be rectified is introduced through aperture 52 into a vessel which contains four devices 49 each comprising a row of cooling tubes on each side of which a layer of metal gauze is soldered. The gas mixture passes in the direction of the arrows 9 through the devices where the water-vapour solidifies as snow on the layers of metal gauze. The dried gas mixture flows through ducts 48 and filter 47 whence it passes up pipe 53 into an annular channel 42 surrounding a rectifying column, the lower part of which is shown at 41. The column is provided with insulating material 43. The liquid fraction leaving the base of the column through pipe 45 enters container 46, and then flows via pipes 50 into the cooling tubes of the devices 49. The liquid boils as it rises up these tubes, and the vapour is returned to the column via ducts 51.
