Title: Method and apparatus for mixing water with fuel for an internal combustion engine
IPC: F02M31/08
Filed: 1975-10-29
Abstract: 1515028 Treating IC engine charge TAKESHIGE SUGIMOTO 29 Oct 1975 [16 July 1975] 44763/75 Heading F1B A method of burning a fuel-air mixture in a combustion chamber of an internal combustion engine comprises the steps of heating water vapour to a gas phase which is free from water droplets which are larger than a predetermined size thereby to produce super-heated water vapour in a state of incipient cracking, heating fuel to a temperature sufficient to produce vaporized fuel, heating air, mixing the super-heated water vapour, vaporized fuel and hot air and burning the resulting mixture under controlled conditions. An apparatus for heating the water, fuel and air comprises a water tank 2, a non-return valve 3, tube 29 and a tube 4 which extends along casing 26 and is then wound helically around heat accumulator rod 13 and leads into pipe 23. Casing 26 is heated by exhaust gas, from pipe 16, which enters through port 20 and leaves through port 27. Water vapour passes through tube 23 to passage 32 which is inside exhaust gas heated jacket 34. Porous iron filter elements 37 prevent the passage of water droplets which are greater than a predetermined size and the vapour is heated by contact with the passage wall. Elements 37 may be heated to red-heat to enhance their reaction with the water vapour so that some of the oxygen is removed. Superheated water vapour leaves by tube 39 which divides and feeds the vapour to two ducts 38, formed in the cylinder head, which are maintained at about 2000C by the heat of combustion. The highly-heated vapour then enters the induction manifold 18 and mixes with air-fuel mixture formed in carburetter 19. Fuel from tank 1, which surrounds and insulates the water tank, is fed by pump 14 through helically coiled tube 48 and passes by 25 to carburetter 19. Jacket 9 which surrounds tube 48 is heated by exhaust gas passing through tubes 24 and 10 so that the fuel is vaporized. Combustion air is filtered through tubes 43, heated as it passes through ducts 42 in the cylinder head and is fed to carburetter 19. The amount of water vapour fed to the engine is regulated by valve 6 which is linked to the throttle valve for synchronous movement therewith. An increased proportion of water vapour may be provided for higher engine speeds. The ratio of water vapour to fuel can be up to 70 : 100. CO content of the exhaust gas is stated to be 0À4% or less.

Title: Improvements in or relating to olefine polymerisation
Inventor: BOND JOHN ALVEY
IPC: C08F297/08
Filed: 1961-12-20
Abstract: Ethylene and propylene are block copolymerized in a reactor, in the presence of a polymerization catalyst and at a temperature of between 10 and 90 DEG C.; a single charge of ethylene is employed and is added to the reactor when the partial propylene pressure therein is at least 0.5 atmospheres.  Preferably the single charge of ethylene, constituting less than 15% of the total weight of propylene, is added after at least 80% of the total yield of solid polymer finally obtained as the product of polymerization has been formed. If desired more propylene may be added for a short period after ethylene addition has been stopped.  The molecular weight of the block copolymers may be controlled by the addition of hydrogen in the propylene feed, in proportion of between 0.02 and 5% molar, in which case 5-15% of ethylene by weight of the total amount of propylene charged is used.  Polymerization is carried out in an inert hydrocarbon diluent.  Catalysts used are generally those of which one component is an organo-metallic compound and the other a compound of a transition metal from Group IV-VI of the Periodic Table. Specifications 877,050, 941,083 and 970,478 are referred to.
