Title: Impact resistant thermoplastic resins
Inventor: OKAMOTO TAKEHIKO
IPC: C08F279/02
Filed: 1970-10-01
Abstract: 1299268 Graft polymerization process TORAY INDUSTRIES Inc 1 Oct 1970 46680/70 Heading C3G An impact resistant resin is produced by emulsion graft polymerizing from 1 to 85% by weight of an ethylenically unsaturated monomer on to 99 to 15% of diene rubber particles in a latch, separating the grafted particles from the aqueous phase of the latex and bulk or suspension polymerizing a monomer phase consisting of at least one ethylenically unsaturated monomer with the grafted particles dispersed therein to give a resin containing 1 to 35% by weight of diene rubber particles. The grafted particles may be separated from the aqueous phase of the latex by (a) mixing the grafted particle latex with the monomer phase used for the bulk or suspension polymerization, extracting the grafted particles into said monomer phase and removing the aqueous phase. Alternatively, the grafted particle latex is coagulated, the aqueous phase is removed and the grafted particles are dried to a water content of at least 20% by weight. The bulk polymerization may be initiated in said monomer phase before the grafted particles are dispersed therein. In the examples, the grafted particles (i) and monomer phase (ii) are as follows: (a) (i) polybutadiene grafted with styrene, acrylonitrile and, optionally, methyl methacrylate, and (ii) the said monomers; (b) (i) butadiene-styrene copolymer grafted with styrene and acrylonitrile and (ii) the said monomers; (c) (i) polybutadiene grafted with methyl methacrylate and styrene and (ii) the said monomers; (d) (i) butadienestyrene copolymer grafted with styrene and (ii) the said monomer; (e) (i) butadiene-styrene copolymer grafted with styrene and acrylonitrile and (ii) methyl methacrylate and (f) (i) butadiene-acrylonitrile copolymer or polyisoprene grafted with styrene and acrylonitrile and (ii) styrene and acrylonitrile.

Title: Improvements in and relating to the production of carbon fibres
IPC: C04B35/52
Filed: 1964-11-17
Abstract: Carbon (amorphous) fibres are coated with a layer of carbide of zirconium, chromium, nickel, titanium or mixtures thereof, by coating said fibres with a layer of heat-decomposable organic carbon-containing material e.g. the metal acetate or formate and then heating to a temperature above 1000 DEG C.ALSO:Carbon (amorphous) fibres are coated with a layer of carbide of zirconium, chromium, nickel, titanium or mixtures thereof by coating said fibres substantially completely with a layer of heat-decomposable organic carbon-containing material, which also contains the said metal and heat-treating so as to form a layer of carbide of the metal substantially completely from the metal and carbon of the said heat-decomposable material.  The fibres are first <PICT:1025499/C1/1> treated to remove volatiles and "flash"-fired at, for example, 2200 DEG  F. for 10 seconds.  The carbon fibres may be in the form of a mat, batt, felt, fabric, sleeving, roving, tape or as bulk fibres. The material used as a carbide source may be chromium acetate, zinc acetate, zirconium formate, nickel acetate, nickel formate, titanium oxide hydrosol stabilized by acetic acid, and organo-metallic compounds such as metal chelating agents and are preferably soluble in a solvent such as water or ethanol. The carbide concentration may be up to 10% by weight of metal, e.g. 2-4%.  Thus, the fibres may be prepared by heating rayon cloth in a closed atmosphere from 300 DEG F. up to 1000 DEG  F. in 50 DEG  increments at short intervals, before "flash" firing.  The carbon cloth may then be immersed in a solution containing 175 g. of chromium acetate.  For 20 minutes, air dried at below 300 DEG  F. and calcined in a non-oxidizing atmosphere of nitrogen, argon, krypton or neon at 1200 DEG  C. for one hour. The titanium oxide hydrosol is prepared by addition of ethyl ortho-titanate to an agitated, cold 25% by weight aqueous acetic acid.

Abstract: 1421049 Intermittent type combustion chambers GOSUDARSTVENNY NAUCHNOISSLEDOVATELSKY ENERGETICHESKY INSTITUT IMENI GM KRZHIZHANOVSKOGO 16 Oct 1973 48215/73 Heading F1L The invention relates to a method of intermittent detonation combustion of a fuel and oxidizer mixture in which the fuel and oxidizer are supplied separately into a combustion chamber there being means for forming a cushion of non-combustible gas between the hot residual combustion gases of the previous combustion phase and the incoming fuel and oxidizer, the cushion of gas being at a temperature below the ignition temperature of the fuel/oxidizer mixture. In Fig. 1 oxidizer is supplied from tank 4 through duct 2 into the combustion chamber 1 and fuel from tank 5 through duct 3; an igniter 6 is provided. The oxidizer and fuel ducts 2 and 3 have associated therewith heat exchangers 7. The arrangement is such that upon firing of the mixture the gases move towards the right to discharge through the open end of the combustion chamber and at the same time gases move to the left and enter the oxidizer and fuel ducts 2 and 3, these gases being cooled by means of the heat exchangers 7. The cooled gases are then forced back into the combustion chamber by the inflowing oxidiser and fuel, the cooled mass of combustion gas acting as a cushion or barrier between the residual hot combustion gases and the fresh oxidizer and fuel charge. A charge of inert gas such as nitrogen may be injected into the cooled gas cushion through injector 8; alternatively the charge of inert gas itself may constitute the cushion of non-combustible gas. In one embodiment the supply ducts 2 and 3 with the heat exchangers 7 are disposed within cooling water spaces.
