Title: Cyclic phosphonitrilic alkyl compounds
Inventor: SEARLE HAROLD TREVOR
IPC: C08G79/025
Filed: 1958-12-01
Abstract: The invention comprises cyclic polyphosphonitrilic alkyl compounds of the general formula (R2PN)n wherein R is alkyl and n is an integer of 3, 4 or more.  They may be obtained by reacting a dialkyl phosphorus trichloride with ammonium chloride at elevated temperature or with liquid or gaseous ammonia.  When ammonium chloride is used the reaction may be carried out either by heating a mixture of the reactants in a tube at 120-200 DEG C. or by refluxing the reactants in an inert solvent, e.g. tetrachloroethane, until evolution of hydrogen chloride has substantially ceased.  The remaining solid products of these reactions with ammonium chloride may then be refluxed in a suitable inert solvent, e.g. chloroform, with a tertiary organic base, e.g. triethylamine to obtain a further yield of the cyclic polyphosphonitrilic alkyls which may be separated from the mixture by extraction with a solvent such as petroleum ether. The individual polymers may then be separated by fractional crystallisation.  When liquid ammonia is used the solid dialkyl phosphorus trichloride is added to the liquid ammonia and stirred for a few hours at room temperature and after extraction of the product with a suitable solvent further yields of the cyclic products are obtained by pyrolysis of the residue at between 200 DEG C. and 400 DEG C.  When gaseous ammonia is used the solid dialkyl phosphorus trichloride is dissolved in symmetrical tetrachloroethane and dry ammonia gas passed through the solution.  The mixture is then refluxed and the cyclic polymer recovered from the solution.  The remaining product may be pyrolysed at 200 DEG  to 400 DEG C. to give a further yield of cyclic polymers.  Examples are given for the production of cyclic phosphonitrilic methyl polymers, the compounds [PN(CH3)2]3 and [PN(CH3)2]4 being specified.

Abstract: <PICT:0898130/III/1> <PICT:0898130/III/2> In making carbon black by cracking hydrocarbon oil, a cylindrical refractory housing 2 comprises the chamber within which the reaction takes place, the same being provided with a spray port 4 containing a spray nozzle 5 which delivers a fine water spray 6 which is directed counter-current to the oil.  The cylindrical refractory housing 2 may be provided with a metallic jacket extending throughout its length, or with a metallic ring at each end, an annular flange 7 being provided in either case. Disposed at the front and rear ends of the cylindrical refractory housing 2 are cylindrical metallic shells, preheat chamber and partial quench 10, provided with annular flanges 12 bolted to the annular flanges 7.  Disposed within each of the cylindrical metallic shell 10 is a metallic tube (as shown at 14 in Fig. 2), the inside diameter of the said metallic tube being the same size as the bore of the cylindrical refractory housing 2 and in alignment therewith. Longitudinal cooling fins 14a and 15a have a welded helical strip 22, 23.  Air enters the inlet 30, is directed around and between cooling fins 14a and finally enters the outer end of tube 14 as combustion air.

Title: Improvements in or relating to methods and apparatus for atomising liquids
Inventor: LANG ROBERT JOSEPH
IPC: F23D11/34
Filed: 1962-10-16
Abstract: 973,458. Liquid feed atomizers. ESSO RESEARCH & ENGINEERING CO. Oct. 16, 1962, No. 39111/62. Heading F4T. [Also in Divisions B2 and H2] A method of atomizing liquids comprises the steps of intermittently impacting at least a part of a flexible screen member by the application of sonic energy thereto and applying liquid to be atomized on to that part of the screen member being impacted. In the apparatus shown in Fig. 1 for producing a spray 76 of fuel-oil, the oil is fed through a pipe 74 or 74<SP>1</SP> on to a circular mesh screen 34 vibrating through the agency of a transducer assembly comprising an aluminium conical sonic energy resonator 16 bonded to a disc-type piezo-electric element 14. The tip of the resonator touches the screen when the transducer is not operating and the sonic energy derives from a high frequency electronic generator 6 having connection to a low frequency voltage source. The transducer assembly is supported by a base element 18 on a three-point suspension comprising a ring 26 and three pointed screws 30 lying on a circumferential line on the resonator 16 coinciding with the node of vibrations in the resonator when the assembly is energized. The screen 34 is held in speced relation to the element 18 through a ring clamping arrangement of which the annular member 36 is adjustably bolted to a block 52 slidably mounted for adjustment purposes on the element 18. The block is secured to the element 18 through a rod 62, nut 64 and wing- nuts 66 and 68. A spring 72 located around the rod 62 acts against the block 52 tending to move it in a direction carrying the screen 34 away from the tip end of the resonator. In an alternative apparatus the circular screen is continuously rotated by an electric motor, the tip of the conical resonator 16 being located at a position off screen centre at the same radius as a wick arrangement which supplies the fuel oil. In yet another form the apparatus comprises a screen in the nature of an endless belt moving in a rectangular path over sprocket assemblies located at each corner. One such assembly is connected to an electric motor and the transducer assembly is disposed in the rectangle, the tip of the conical resonator and an oil-feed wick arrangement being associated with the same straight run of the screen. Fig. 4 illustrates a conical resonator 128 having an axially disposed oil-feed duct therethrough. In a modification of this type of resonator the axial duct only extends to the cross-sectional plane of the circumferential line coincidal with the node of vibrations, the oil being fed to the duct through another duct disposed radially of the resonator along the said plane.

Carbon dioxide is used as a solvent or dispersion medium for polymerizing epoxides, optionally in the presence of other organic solvents and an ionic catalyst, and separation of the product can thus be readily achieved by maintaining the polymerization system at above the boiling temperature of the monomer used and reducing the system to atmospheric pressure. The amount of carbon dioxide added is preferably from 0À1 to 100 times the weight of the epoxide employed and the polymerization temperature is normally between - 80‹ and +200‹ C. Epoxides specified are alkylene oxides, such as ethylene oxide, propylene oxide and butene oxides; substituted alkylene oxides such as epichlorohydrin, epibromohydrin, epifluorohydrin, trifluoromethyl ethylene oxide and vinyl chloride epoxide; epoxy ethers such as hexylglycidyl ether, phenylglycidyl ether and 2-chloroethylglycidyl ether; and styrene oxide, α-methyl-styrene oxide and butadiene monoxides.

Title: Method of making articles from foamed elastomeric material
Inventor: CHARVAT VERNON KENNETH
IPC: C08J9/00
Filed: 1960-11-17
Abstract: A method of making a moulded article from a hardenable foamable liquid synthetic resin composition comprises placing a body of the composition in a rotary mould, rotating the mould and the composition during foaming and hardening, and stopping the rotation when the body is of substantially increased viscosity but before hardening is complete to allow the gas bubbles to increase in size and the surrounding web structure to thicken in the radially outer portion of the body.  There may also be present in the resin composition a granular abrasive, which initially, on being subjected to the centrifugal force, collects in the peripheral portion of the body (e.g. a polishing or grinding wheel) and then upon completion of the foaming, the grains are carried by the thickened web, the space between them being occupied by spherical cells resulting from the enlarged gas bubbles. As a result of the centrifugal moulding the surface portion of the article develops on the outer periphery a skin substantially free of bubbles and of relatively higher density. One specified synthetic resin is polyurethanes (from polyester and polyisocyanate).  Preferably the polyester contains hydroxy to carboxy groups in a ratio from 4 to 1 to 1 1/2 to 1. Ethyl cellulose, polymethylolphenols and zinc stearate may be added to the mixture.  A suitable epoxy resin mixture contains also polyoxyethylene sorbitan monolaurate and a blowing agent (p,p1-oxybis-benzene-sulphonyl hydrazide or N,N1-dimethyl-N,N1-dinitrosoterephthalamide). Resins or elastomers wherein air or other gas are entrapped during mixing can also be used.
