Title: Apparatus for dissolving nuclear materials
IPC: B01F1/00
Filed: 1964-06-21
Abstract: A subcritical nuclear fuel dissolving apparatus comprises a subcritical dissolving vessel 1 in which the fuel to be dissolved is placed and which is located above a subcritical tank 2 containing a treatment solution comprising an aqueous solution of an acid, e.g. HNO3, the volume of this solution contained in the tank 2 being variable according to the quantity of fuel to be dissolved, a boiler 3 which supplies a mixture of solvent and of steam arising from the water of the treatment solution and which assures the circulation of the mixture, the boiler 3 being situated at a position laterally spaced from and below the tank 2, a liquid/vapour phase separator 4 located above the vessel 1, and pipes such as 9, 10 for connecting the different elements of the apparatus. The vessel 1 terminates in a frusto-conical base and is fitted with a detachable cover for the introduction of the nuclear fuel, its dimensions being adapted to those of the fuel to be dissolved. The tank 2 is preferably flat and of trapezoidal shape. The steam from the boiler 3, as well as nitrous vapours when the solvent is HNO3, forms together with the solution a mixture having a lower sp.gr. than that of the solvent which entrains the latter in the liquid phase. The vessel 1 and the tank 2 are fitted with two tubes 9, 10 which serve to eliminate nitrous vapours, which vapours are oxidized by air injected into the tubes and the resulting oxides condensed in condenser 6 if the temperature is sufficiently low. The oxides which are not condensed in the condenser 6 are sent through a tube 11 into a NaOH absorption column. The steam is separated from the solution within the separator 4, sent to the condenser 6 and then returned to the boiler 3. In order to commence the dissolving process in a rapid and uniform manner, air is injected into the apparatus immediately beyond the outlet of the boiler 3 at 7, this injection being stopped as soon as the circulation has achieved a steady state. The treatment solution is drawn off through a conduit 8 at the foot of the apparatus.
Patent ES-308198-A1 (ES)
Title: Liquid fuel pumping apparatus for internal combustion engines
IPC: F02M41/14
Filed: 1965-01-08
Abstract: In a fuel injection pump in which the delivery is regulated by controlling the fuel supplied thereto by a feed pump, a by-pass valve is arranged to be opened by a spring to by-pass the regulating means to supply excess fuel for starting, the by-pass valve being closed by feed pump pressure when the engine starts. The combined rotating cylinder/distribution type pump shown is regulated by a feed pump pressure actuated shuttle which feeds metered volumes of fuel to the pump cylinder, the volume being regulated by a fly-weight governor controlled throttle 40 regulating the flow to a chamber 42 which feeds the shuttle. A passage 57 from the chamber leads to a port 52 which communicates with one of the inlet passage 23 when the shuttle chamber is in communication with another passage 23, communication between the passage 57 and port 52 being controlled by a valve 53 biased to the open position by a spring 54 and to the closed position by feed pump pressure and held in this position by a manually releasable lock 60 (see Div. E2). To start the engine the lock is released so that the valve opens and fuel by-passes the shuttle and flows directly to the pump cylinder. When the engine starts the feed pressure closes the valve and the lock re-engages. Timing is controlled by feed pump pressure acting through a passage 66 on a spring loaded piston controlling the angular position of the drive cam ring to ensure full retardation on starting the valve 53 is arranged to close a port 68 supplying the passage 66. The lock returns to locking position when the engine starts even if it is held down.

Title: Process of suspension polymerization utilizing synergistic suspension system
IPC: C08F2/18
Filed: 1966-12-19
Abstract: A suspension polymerization process is carried out in the presence of an agent comprising a water-soluble polymeric carboxylic acid and a water-soluble polymeric alcohol. The agent is used in particular for the polymerization of a vinyl or vinylidene aromatic monomer, together with a comonomer if desired, e.g. acrylonitrile or methacrylonitrile. The polymerization may be carried out in the presence of partially polymerized material or a preformed polymer, especially a rubber, in which case the monomer is at least in part grafted on to the rubber. The partially polymerized material is formed by bulk polymerization of the monomer to form a syrup which is then mixed with water and polymerization is completed in suspension. The polymeric carboxylic acid agents specified include copolymers of acrylic acids and alkyl acrylates, of vinyl acetate and maleic anhydride, or of ethylene and maleic anhydride, or poly(meth)acrylic acid. The polymeric alcohol may be of formula wherein X is hydrogen, n is at least 10 and at least 5 mol per cent but not more than 35 mol per cent of X is an ester group. In Example 1 a prepolymer syrup is produced. by polymerizing styrene in the presence of a polybutadiene rubber and polymerization is completed in an aqueous dispersion containing polyvinyl alcohol with residual acetate groups and an acrylic acid/2-ethyl hexyl acrylate copolymer. A partially hydrolysed polyvinyl acetate is used as the polymeric alcohol in Examples 2 and 3. Examples 4 to 8 are similar to Example 3, except that the polymeric acid used is (4) polyacrylic acid, (5) a vinyl acetate-maleic anhydride copolymer, (6) polymethacrylic acid and (7) an ethylene-maleic anhydride copolymer. In Examples 9 and 10, styrene and acrylonitrile are partially polymerized in the presence of a polybutadiene rubber prior to dispersion of the syrup in an aqueous medium containing partially hydrolysed polyvinyl acetate and an acrylic acid/ 2-ethylhexyl acrylate copolymer.

Title: Selective xerographic fuser
IPC: G03G15/20
Filed: 1967-10-09
Abstract: An apparatus for fixing heat fusible toner images to a support, comprises a heated movable surface which feeds the support, held in close contact with the surface, past an infrared source 43 to effect fusing. As shown, the movable surface is a roller 20 to which a sheet beading a toner image is held by electrostatic forces. The roller 20 has a metal cylinder 30 having an insulating coating 29 of tetrafluorethylene surrounding a heating element 35 connected to a temperature control 33. An exhaust 37 connected to a vacuum pump 34 withdraws air from the roller under the control of temperature control 33 to maintaining the temperature of the roller 20 constant. The infrared source 43, Fig. 1, comprises a quartz lamp in a reflector 43 extending axially of roller 20. An exhaust manifold 44 removes gases created during fusing to prevent a film building up on the reflector. A stripper 65, Fig. 2, removes the sheet from the roller 20 and guides it to baffles 68. Residual toner on the roller 20 is attracted by a wick of tetrafluorethylene impregnated with silicone oil in a housing 75. Unfused toner is removed from the sheet by a brush 5, Fig. 1, rotated within a hood 53 connected to vacuum. Sheets are supplied to the drum 13 from a supply 10 provided with heaters 102 and a humidity control.

Title: Process for preparing oxirane compound
IPC: C01G39/00
Filed: 1967-11-23
Abstract: Oxirane compounds are prepared by catalytically reacting an olefin with an organic hydroperoxide to form a by-product alcohol, at least part of the catalyst being removed from the reactor effluent before the by-product alcohol is recovered from the effluent. The catalyst is preferably removed by treating the effluent with a basic material, e.g. a hydroxide, carbonate, bicarbonate or oxide of an alkali or alkaline earth metal or a basic organic compound, which may be used in the presence of water. The olefin used as starting material may carry a substituent, e.g. a hydroxy group, an ether group, a carboxy ester group, a ketonic group or a halogen. It may, for example, be an oil or a polyolefin. Preferred catalysts are the naphthenates and carbonyls of molybdenum, titanium, tungsten, vanadium rhenium, niobium, tantalum, selenium, chromium, zirconium, tellurium and uranium. Examples are given of the oxidation of propylene with ethylbenzene hydroperoxide to give propylene oxide and [alpha]-phenyl ethanol.
