Title: 2, 6-dihalo-pyrimidine-4-carboxamido dyestuffs
IPC: C09B62/04
Filed: 1960-02-05
Abstract: 2:6-dichloropyrimidine - 4 - carboxylic acid chloride is made by reacting with thionyl chloride 2:6-dichloropyrimidine-4-carboxylic acid which is prepared by reacting 2:6-dihydroxypyrimidine-4-carboxylic acid with phosphorus oxychloride.ALSO:The invention comprises dyes of the general formula <FORM:0921963/IV(a)/1> where F is the radical of an organic dyestuff, X is an acid, salt-forming, water-solubilizing group, n and m are each whole numbers, R is hydrogen or an alkyl radical containing 1 to 4 carbon atoms and Y is a 2:6-dihalogen-4-pyrimidyl radical. Organic dyestuff radicals mentioned are those of the azo, anthraquinone and phthalocyanine series. The dyes are made by reacting an appropriate organic dyestuff having at least one acylatable -NHR group where R has the meaning above with a 2:6-dihalogen-pyrimidine-4-carboxylic acid halide, or in the case of azo dyestuffs by coupling diazo and coupling components which contain -NHR groups acylated by the radical -CO-Y. Azo dyes may be of the monoazo or disazo series and may be metallized before the acyl group -CO-Y is introduced. Examples are given. The dyes dye cellulose fibres in a variety of shades in conjunction with an alkali treatment, possibly at raised temperature.

Title: Improvements in or relating to nuclear reactor fuel elements
IPC: G21C3/20
Filed: 1965-02-06
Abstract: A fuel element, comprising a uranium or uranium base alloy in a sheath of a magnesium base alloy also containing zirconium, has a substance diffused through at least part of the sheath wall thickness which prevents diffusion of plutonium through the sheath by forming an intermetallic compound with the plutonium. The substance is preferably aluminium, although it may alternatively be aluminium-silicon, copper, nickel, or copper and nickel based alloys. The substance is preferably applied initially to the fuel body in the form of a wrapping of foil, although it can be applied to the sheath interior, and may in both cases be applied alternatively by vacuum deposition, electro deposition, spraying or dipping. The fuel and sheath are assembled with a layer of the substance between them, and heat and pressure applied. In the case of aluminium, it forms an intermetallic compound with the sheath zirconium, and consequently sufficient aluminium must be used to ensure that an uncompounded layer has diffused into the can which will combine with the plutonium as it is formed during fission of the fuel element. The diffusion is not necessarily completed during manufacture it may continue to take place from the remaining layer between the fuel and sheath during use in the reactor.

Title: Method for preparation of urania sols
IPC: C01G43/025
Filed: 1966-08-24
Abstract: A stable urania sol is prepared by precipitating hydrous urania from an aqueous uranou nitrate solution by adding an alkaline reagent, to a final pH of 6À0-7À3, separating, washing and heating the precipitated hydrous urania at 60-80 C., all under a non-oxidizing atmosphere. The uranous (tetravalent uranium) solution may be supplied as an organic salt such as uranous formate or by reduction of hexavalent uranium in solution, such as uranyl nitrate solution obtained in solvent extraction reprocessing of spent nuclear reactor fuels, by hydrogen with a platinum catalyst, such as 0.001 molar chloroplatinic acid, and in the presence of a nitrite-inhibiting agent such as 0À25-0À3 molar urea. The solution should have about 0.5 molar tetravalent uranium concentration and a nitrate to uranium ratio of 4 to 1. The alkaline reagent may be any strong base, especially ammonium hydroxide, and the atmosphere may be an inert gas. The sols may be used alone or mixed with other actinide sols to prepare nuclear reactor fuels.

Title: Improvements in Fuel Injection Systems for Internal Combustion Engines
IPC: F02D41/32
Filed: 1967-10-28
Abstract: Fuel is injected into the intake manifold 12 by solenoid actuated valves 13 fed by a pump 16 and the fuel pressure is controlled by a regulator 19 to a value exceeding the intake manifold pressure by a predetermined amount. The regulator 19 may comprise two chambers (51, 52) separated by a spring-biased diaphragm (53) with a cone (54) which controls the flow of fuel, fed to one of the chambers (52), through a return pipe 55 to the fuel tank 18. The other chamber (51) is connected to the intake manifold 12. The period of opening of the injection valves is controlled by a monostable multi-vibrator 25. The period is dependent upon the position of the movable core 39 of a transformer which couples the collector of the output transistor T 2 to the base of the input transistor T 1 . The position of the transformer core 39 is controlled by the pressure in the inlet manifold 12, and each cycle of the multi-vibrator is triggered by the cam 31 rotating with the crank shaft 17 and operating a switch 32 to connect a capacitor 33 to the positive lead 26, the transistor T 1 being rendered non-conductive. The pump 16 is driven by the crank-shaft 17 or an electric motor.

Title: Improvements in or relating to the coating of glass articles
IPC: C03C17/25
Filed: 1968-05-09
Abstract: A uniform film is formed on the surface of a sheet of glass by immersing the sheet in a coating liquid, locating the sheet in the liquid, and gradually lowering the level of the liquid about the stationary sheet at a rate such that the liquid meniscus sweeps down the surface of the sheet leaving a continuous static and optically uniform film of the coating liquid on the surface of the glass as the level of the liquid recedes. The level of the liquid is lowered at a constant rate controlled to avoid turbulence of the liquid meniscus thereby leaving a uniform film of liquid on the glass surface, where a part of the surface of the glass is to remain uncoated, that part is treated with an agent, e.g. a waxy substance, which renders the surface non-wettable by the coating liquid. The coating liquid may be an aqueous solution or a solution in an organic solvent of an organic compound, e.g. an organic compound of silicon or zirconium, water-soluble compounds of cobalt, nickel, manganese, iron, copper, silver or tin. Apparatus for producing the uniform film on a surface of a glass sheet comprises a tank for holding a coating liquid, means for locating the sheet in the tank so as to be completely immersed in the liquid, means for gradually lowering the level of liquid in the tank through an outlet at or adjacent the bottom of the tank, and a pump for recirculating the liquid to the tank when the coated sheet has been removed from the tank. The apparatus may be for producing a uniform film on the surface of glass sheets wherein the tank is in the form of a deep trough for receiving the sheets, a frame for locating the lower edges of the glass sheets which is mounted in the bottom of the trough, and the sides of the trough converge towards the bottom of the trough at an angle such that there is a constant rate of fall of the liquid level in 'the tank when the outlet is opened.

IPC: D06F37/22
Filed: 1970-02-27
Abstract: In a domestic washing machine, the washing and spin drying drums provided with automatic balancing to counteract imbalance due to uneven distribution of the drum contents. A mass of water is fed into a member rotatable about the same axis as the drum, and is passed from there into compartments in the drum appropriate to effect balance.

The drum 5 is driven by the motor 9, and the disc 26 is caused to rotate by friction forces at the pin 25, mounted in the shaft 8. The projection 29 assures a position opposite to the point of imbalance of the drum 5 and fills with water. A flow of water from 29 passes through nozzle 30 and the annular opening 19, to compartments in the front and rear walls 14, 15 of the drum to compensate the imbalance. Nozzle 30 is bent to compensate for Coriolis forces due to water flow.
