Title: Method of treating oil shale
IPC: C04B7/30
Filed: 1961-01-26
Abstract: A raw material for use in the production of cement is produced by treating oil shale in grannular or size reduced form in a fluidised bed, at e.g. 400-650 DEG C., operated with a deficiency of O2 relative to the total combustible organic matter to effect combustion of only the more volatile constituents of the oil shale and the liberated heat is used to raise steam.  The oil shale may be milled up to 5 mm. grain size.  The residence time of the shale in the fluidised bed may be from a few seconds to a few minutes using a gas containing less O2 than air or a deficiency of air whereby 2/3 rds of the organic matter is burnt yielding a combustion gas containing not more than 0- 1/2 %O2.  Steam may be raised by cooling tubes in the bed and radiation chamber above the fluidised bed.  The solid C left on the shale may be used to provide at least part of the heat required for sintering, e.g. on a sinter board.

[Class 83 (i)] Clamping moulds .- Pressure-casting apparatus comprises mould parts A, B, the lower part B being yieldingly mounted and containing a pressure chamber D closed at the bottom by a press plunger G, the longitudinal axis whereof is in the direction of movement of a driving member which moves down the upper part A to close the mould and then continues to move the closed mould downwards relativelv to the plunger G so as to force metal from the chamber D through gates E into mould cavities C. The lower mould part B may be carried by rams K and normally pressed against abutments L by liquid under pressure in cylinders H. The plunger may be fixed to a base-plate M or attached to a ram supported in a hydraulic pressure cylinder. The upper mould part A is attached to a movable platen O fixed to a ram operated by a hydraulic cylinder P on the crosshead Q. Where the plunger is supported hydraulically, the platen O may be crankoperated. In another form, Fig. 3, the mould part B is supported on a hollow ram K in a hydraulic cylinder H and the plunger G is fixed to a ram G<1> sliding within the ram K and normally held down by a spring G<11>. The cylinder H is connected through a non- return valve H<1> with a low-pressure vessel H<11> and through a non-return valve T with a highpressure vessel U which carries a discharge pipe V and a safety valve W. As the mould and ram K fall, pressure is transmitted through the liquid to cause the plunger G to rise against the spring G<11>, the maximum pressure on the plunger being limited by the pressure in the vessel U. Towards the end of the ram stroke, the vessel U may be cut off, so that the final pressure of the plunger G is not limited. After pressing, the ram K is raised by liquid supplied from the vessel H<11>. The vessels U, H<11> may be connected to the hydraulic cylinder of the press or they may be directly connected to form a closed circuit.

Title: Improvements in or relating to control apparatus for nuclear reactors
Inventor: JONES JACK
IPC: G21C7/22
Filed: 1960-01-29
Abstract: 927,438. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 24, 1961 [Jan. 29, 1960], No. 3350/60. Class 39 (4). A control system includes tanks of boric acid 4 and heavy water 7 and a closed vessel 1 containing a mixture of these liquids and a blanket of nitrogen. Boric acid is fed to the vessel by gravity so that the inflow varies with the liquid volume in the vessel, and heavy water is fed by pump 14; the nitrogen pressure is normally enough to prevent inflow of either liquid. The mixture flows in a circuit including reactor core 11, cooler 18, vented reservoir 12 and pump 13; pump 13 is stronger than pump 14. Loss of reactivity in the core, as measured by detector 15, causes increased pumping of heavy water, thus diluting the mixture and reducing absorption of neutrons; increased reactivity decreases the pumping, thus reducing the pressure in the vessel 1 and allowing addition of boric acid to the mixture. A boric acidheavy water separator 33 is provided. Specification 803,701 is referred to.

Title: Improvements in fuel injection systems for internal combustion engines
IPC: F02M69/00
Filed: 1945-02-12
Abstract: 586,261. Regulating. HOBSON (AIRCRAFT & MOTOR) COMPONENTS, Ltd., H. M., and GREENLAND, L. S. Feb. 12, 1945, No. 3449. [Class 7 (vi)] A spring 50 acting on a diaphragm 39 provides a slow running adjustment in a fuel supply system of the type in which fuel under pressure is fed through a conduit including a metering orifice 25, and in which the pressure difference across the orifice is maintained proportional to the square of the engine speed by means of a centrifugal impeller 37 co-operating with diaphragm 39 actuating the pressure regulating valve 40. The force exerted by spring 50, adjusted by a screw 51, is inappreciable at the high metering pressures prevailing at medium and high boosts, but-becomes effective at slow running and serves to enrich the mixture. The small pressure difference produced across the diaphragm 39. serves for venting through the venting orifice 43, as described in Specification 586,260 and the spring also counterbalances forces exerted on the valve 40 by the fuel if it is of the unbalanced type. The device may be used for the supply of anti-detonants. In a modification in which the fuel flow at slow running is reduced, the spring exerts a tension on the diaphragm. The pressure regulating valve in this case must be of the balanced type, and venting from the eye of the impeller takes place to the suction side of the fuel-delivery pump. Specifications 419,113, 566,323, and 586,259 also are referred to.

Title: Improvements in the production of thallium sulphide photoconductive cells
IPC: H01L31/0264
Filed: 1944-02-25
Abstract: 580,550. Light - sensitive cells. STARKIEWICZ, J., STOW, R. L., and WRIGHT, C. S. Feb. 25, 1944, No. 3571. [Class 40 (iii)] Light-sensitive cells in which the light sensitive element is formed of thallium sulphide are stabilised by treatment with mercury vapour, preferably following the sensitisation of the cell. In carrying out the invention the thallium sulphide element is formed as a layer with a sufficiently porous micro-crystalline structure to ensure penetration of the mercury into the layer, the thallium sulphide being preferably prepared in the manner described in Specification 580,551. This layer may be deposited on a graphite grid having 25 lines per inch, formed for example at d (Fig. 2) on the wall of an evacuated bulb a. The bulb a is then heated at a temperature of 300‹-320‹ C. in a removable oven f while oxygen is admitted at a pressure of 0.2 mm. The mercury is contained in the end of a side tube s which is immersed in liquid air to prevent escape of mercury into the bulb and to condense sulphur dioxide given off during the oxidation of the sulphide. At the end of the oxidizing bake the oven temperature is reduced to 200‹-250‹ C. and the oxygen supply cut off. The bulb is then pumped out and sealed from the pump at the tap h and the liquid air is removed from tube s to allow the trapped sulphur dioxide to evaporate and act on the layer d, followed by mercury vapour. The oven is maintained at about 200‹ C. for ten minutes and then tap h is opened and any excess sulphur dioxide is pumped out. Tap h is then closed and oven f raised and bulb a allowed to cool to room temperature while still under the action of mercury vapour. The bulb is then sealed off. The mercury vapour is said to affect the resistance characteristics of the element so as to allow the oxidation treatment to be carried out while the bulb is cooled to a low temperature so that the resistance, charac-. teristics can be satisfactorily controlled by varying the length of treatment. In the method described in the Provisional Specification the pressure of mercury is varied during the preparation of the cell.

Title: Improvements in or relating to methods of preventing corrosion of metallic petroleum refining apparatus and compositions therefor
IPC: C23F11/18
Filed: 1957-02-06
Abstract: The corrosion of metallic apparatus used for the distillation of crude petroleum or a fraction thereof is inhibited by mixing a small proportion of an aqueous alkaline solution of an ammoniacal copper carbonate complex with the distilland.  The treating solution is prepared from a concentrate of an ammoniacal copper carbonate complex which contains 5 to 16% by weight of copper. The concentrate may be made by passing carbon dioxide and ammonia gases into water, while maintaining the temperature between 75 DEG  and 80 DEG  F., and then adding (with stirring) a quantity of commercial copper carbonate equal to the combined weights of the carbon dioxide and ammonia.  The solution so formed is then mixed with sodium carbonate solution to form the final treating solution.  A composition may be prepared in the dry state by mixing ammonium bicarbonate (5% by weight), copper carbonate ( 1/2 %), and soda ash (94 1/2 %).  This dry material is dissolved in water at the time of use.  The treating solution is effective in obviating corrosion in apparatus used for distilling sulphurious crude oils.  The treating solution will ordinarily be injected into the oil entering the distillation system.  In most cases about 2 gallons of treating solution per 1000 barrels of oil will provide satisfactory treatment.  The solution is also found to be effective in removing acidic, gum-forming and other undesirable constituents present in many distillate fractions produced from crude oil and from the cracked products thereof. Such fractions are preferably vaporized, and the vapours are then contacted with the treating solution.
