Title: A method for the production of metallic uranium or uranium alloys
IPC: C22B60/02
Filed: 1957-08-28
Abstract: In a method of producing uranium or uranium alloys by reducing a uranium double fluoride by means of an alkali metal, alkaline earth metal or aluminium, the previously dried uranium double fluoride is heated to a temperature between 110 DEG C. and its melting point to increase its apparent density, ground to a suitable grain size, mixed with reducing agent, the mixture is tamped to consolidate it and heated to reaction temperature in a sealed vessel.  An element capable of alloying with uranium may be included in the reaction mixture, e.g. in the form of a reducible fluoride.  Reduction may be initiated by heating the mixture as a whole or by a local heating. The mixture may also contain at least one substance such as iodine which itself undergoes exothermic reaction and thereby imparts heat to the mixture.  In an example zinc fluoride is included in the reaction mixture.  The reaction vessels may be a graphite container which is placed in a sealed metal container or it may be a sealed metal container internally coated with a refractory such as calcined dolomite, magnesium oxide or magnesium fluoride.

Gaseous mixtures are continuously resolved by passing an absorbent medium and a carrier gas continuously through a zone in intimate contact and at an angle to one another, the mixture being fed to the zone at a point where both the gas and absorbent enter, and collecting a component of the mixture from either the absorbent or the gas. An absorbent medium 1 in sheet form passes over edge 3 to fall as a vertical sheet 4 to another edge 5, whilst gas manifold 6 directs streams of gas by pipes 7 across the sheet 4 perpendicular to the movement of the sheet. The mixture e.g. a ternary mixture, is added at 8 and the components separate according to the areas 9, 10 and 11 wherein 9 is the least volatile and 11 the most volatile components. In two other embodiments (Figs. 2 and 3, not shown) the absorbent medium may be a particulate material and passes down a thin rectangular container or a series of parallel tubes having perpendicular connections between adjacent tubes, the particulate material being controlled above the containers by rotary valves.

High frequency discharge apparatus, e.g. a klystron, comprises an electron gun 13, at least one cavity resonator 15 having an interaction gap 38 of predetermined spacing, and a collector assembly 16, wherein the collector assembly includes temperature responsive elements for controlling the gap spacing whereby the resonant frequency of the cavity is temperature compensated. As shown, the collector electrode is a tube 41 which is cooled by cooling liquid flowing over fins 44 attached to the outer surface of the tube 41. One end of the collector is attached to a flexible wall 33 of the resonator 15, the other end being attached to a body portion 12<SP>1</SP>. With increase in temperature, there is a tendency for the gap spacing 38 to increase owing to the expansion of the apertured partitions 32 and 33; this can be counteracted by making the collector tube 41 and body portion 12<SP>1</SP> of materials having different coefficient of expansion, e.g. of steel and copper respectively. Specification 1,004,977 is referred to.

Abstract: 1518789 Hot water systems; solar heaters B R CARTER 24 June 1975 [24 June 1974] 27906/74 Headings F4A and F4U In an apparatus for storing hot water, a hot water storage tank 1 is provided with adjustable inlet means for supplying hot water from a solar heater 6 to any one of a range of levels in the tank in response to a predetermined relationship between the hot water temperature and the temperature gradient within the tank such that the level increases and decreases with the temperature of the hot water. As shown in Fig. 1, water is supplied to the hot water storage tank 1 through a mains inlet pipe 3 and an outlet pipe 2 is provided from which hot water is drawn for use. Water to be heated is drawn from the lower region of the tank 1, through a pipe 4 by a pump 5, through the solar heater 6 and the heated water is returned by way of a pipe 7. The pipes 4 and 7 are connected to flexibly mounted pipes 14 and 8 respectively. The pipe 8 is responsive to the temperature difference measured by sensors 10, 11 which act through a controller 12 and a motor 13 which acts to raise and lower the pipe 8 so that hot water is supplied to the tank at a level of slightly lower water temperature. Thus, under conditions of high solar energy, water is heated to a high temperature in the solar heater 6 and is supplied to the tank at a high delivery level. Under conditions of low solar energy, water is heated to a lower temperature and is supplied to the tank at a correspondingly lower delivery level. The pipe 14 is responsive to the temperature difference measured by sensors 16, 17 which act through a controller 18 and a motor 19.

Title: Improvements in the manufacture and production of vinyl compounds
IPC: C07D207/32
Filed: 1935-10-10
Abstract: N-Vinyl compounds are manufactured by reacting acetylene at elevated temperatures on pyrrole or an organic compound containing the pyrrole ring in the presence of an alkali metal or a substance having a strongly alkaline reaction and of ammonia or a heterocyclic compound containing nitrogen in tertiary combination, e.g. pyridine, quinoline, isoquinoline or their derivatives, or on a secondary diarylamine in the presence of an alkali metal or a substance having a strongly alkaline reaction and of ammonia.  The added substances may be used in small amounts, e.g. the amount of pyridine present in carbazole recrystallized from pyridine is sufficient, or in such amounts that they act as solvents.  A comparative experiment shows the effect on the reaction of carbazole dissolved in cyclohexane at 180 DEG  C. with a mixture of acetylene and nitrogen under pressure in the presence of potassium hydroxide, of the addition of pyridine, ammonia (used in place of nitrogen to dilute the acetylene), quinoline, 8-hydroxyquinoline and 8-hydroxyquinaldine.  In an example, diphenylamine is treated as above in the presence of potassium and ammonia, yielding N-vinyldiphenylamine.

Title: Improvements in the production of carbon-disulphide
IPC: C01B31/26
Filed: 1930-09-20
Abstract: A mixture of hydrogen sulphide and carbon dioxide, obtained for example by washing coal gas with water and heating or reducing the pressure on the solution, is led over glowing carbon, when conversion into carbon disulphide, hydrogen and carbon monoxide occurs.  An inert diluting gas such as nitrogen may be present. Carbon disulphide may be separated by cooling or absorption in active charcoal and the gas mixture containing unconverted hydrogen sulphide added to the crude coal gas; or this hydrogen sulphide may be extracted and used for making carbon disulphide or for other purposes.  In an example, by conducting a gas containing 52 per cent hydrogen sulphide, and 44 per cent carbon dioxide over coke at a temperature of about 950 DEG C., a 90 per cent conversion of hydrogen sulphide to carbon disulphide occurs, after separation of which, together with unconverted hydrogen sulphide, a gas containing 66 per cent carbon monoxide and 34 per cent hydrogen is obtained.
