Title: Improvements in or relating to nuclear reactor fuel elements
Inventor: INGLEBY BRYAN EDWARD
IPC: G21C3/62
Filed: 1962-04-13
Abstract: A nuclear fuel body (see Division G6) includes spheroids of uranium carbide coated with at least one layer of silicon carbide, and preferably with two layers of silicon carbide, separated by a layer of pyrolytic carbon.  The coatings are formed by vapour deposition from methyl trichlorosilane, the spheroids forming a fluidized bed during the process.  The Coating apparatus, comprises a bed chamber 20 formed from graphite parts 9, 10, 12 includes a gas inlet orifice 15, which is sealed by a tungsten carbide ball 16 if the fluidizing gas supply is curtailed.  A single water cooled tube 17 delivers all fluidizing, purging and reactant gases. The bed is heated by passing an electrical current through a graphite resistance sleeve 7, and temperatures are monitored by a thermocouple 19. Exhaust gases pass from a water cooled header 21 to scrubbing and filtering equipment. In operation, the bed is purged at 1000 DEG C. in a stream of argon, cooled to 200-300 DEG C., loaded with spheroids, and heated to 1500 DEG C. during the passage of a small flow of hydrogen.  The hydrogen flow is then increased to fluidize the bed and reactant gas included with the hydrogen.  The methyl trichlorosilane is picked up from its containing vessel by a bypass portion of the hydrogen flow.  After cooling, the spheroids are removed from the apparatus, washed, dried, leached in nitric acid, washed and dried.  Further coatings of silicon carbide may be added in the same way, and carbon coatings may be sandwiched therebetween using the same apparatus, but in conjunction with argon fluidizing gas containing acetylene or methane as the reactant gas. <PICT:1031154/C6-C7/1>

Title: Improvements in or relating to nuclear-chlorinated aromatic compounds
IPC: C07C255/49
Filed: 1960-04-27
Abstract: Sodium hydroxylamine disulphonate, HON: (SO3Na)2, is produced, in aqueous solution, by adding an aqueous solution of sodium bisulphite to an aqueous solution of sodium nitrite, at a temperature a little below 0 DEG  C., and then passing sulphur dioxide into the cooled solution until is shows an acid reaction.  A solution of sodium hydroxylamine monosulphonate may be obtained by storing or heating a solution of the disulphonate.  Specification 862,863 is referred to.ALSO:Beta-2, 6-dichlorobenzaldoxime is produced by reacting 2, 6-dichlorobenzaldehyde with an alkali metal salt of hydroxylamine mono- or disulphonic acid. This b - oxime is believed to be the geometric isomer of the oxime produced by the action of hydroxylamine on 2, 6-dichlorobenzaldehyde. The b -oxime may be converted directly into 2, 6-dichlorobenzonitrile, or the conversion may be carried out via the acetyl derivative of the oxime. In Example 1, an ethanolic solution of 2, 6-dichlorobenzaldehyde is added to an aqueous solution of sodium hydroxylaminedisulphonate, and the mixture is heated at 75 DEG C. for 30 minutes whereby crystalline b -2, 6-dichlorobenzaldoxime is formed. The oxime is acetylated by heating, at about 85 DEG C., with acetic anhydride; and the acetyl derivative is treated with pyridine whereby 2, 6-dichlorobenzonitrile is produced. In Example 2, the nitrile is obtained directly from the oxime by boiling it with acetic anhydride. In Examples 3 and 4, the nitrile is produced by reacting the oxime with thionyl chloride and phosphorous oxychloride, respectively. The oxime and its acetyl derivative may be used in compositions for influencing plant growth.ALSO:A composition for influencing plant growth comprises beta-2,6-dichlorobenzaldoxime, or its acetyl derivative, and a solid or liquid inert carrier.  A dust preparation for combating premature sprouting of potatoes comprises 4% of active substance, 16% of kieselguhr and 80% of magnesium marlstone.  A specified liquid preparation comprises 25% of active substance dissolved in 61% of xylene and 6% of methyl ethyl ketone with the addition of 8% of an emulsifying agent.  Wettable powders may be prepared using wetting agents such as fatty alcohol sulphates or alkyl-aryl sulphonates, dispersion agents such as lignin sulphonate, and carriers such as kaolin, chalk, pipe clay, magnesium marlstone, and attapulgite.  For the preparation and chemical configuration of beta-2,6 - dichlorobenzaldoxime see Division C2.  Specification 862,863 is referred to.ALSO:Germination of seeds is influenced, e.g. premature sprouting of potatoes is retarded, by treating them with a composition comprising, as active substance, beta-2,6-dichlorobenzaldoxime, or its acetyl derivative, and a solid or liquid inert carrier.  A dusting composition may comprise between 1 and 20%, by weight, of active substance in admixture with talc, kieselguhr and/or magnesium marlstone.  Specification 862,863 is referred to.

Title: Process for the production of nicotinic acid benzyl ester
IPC: C07D213/803
Filed: 1956-05-14
Abstract: Nicotinic acid benzyl ester is prepared by heating a mixture of nicotinic acid and benzyl alcohol in the presence of a water-entrainer such as toluene or xylene, with removal of water from the system, wherein the amount of water-entrainer employed is small enough to enable temperatures of 130-190 DEG  C., preferably 150-160 DEG  C., to be maintained in the reaction mixture.  It is preferable to carry out the reaction with the liquid surface as large as possible in which case the reaction mixture may be vigorously stirred.  The reaction may be carried out by passing a solution of nicotinic acid in benzyl alcohol from above through a heated vertical column to a water-entrainer in counter-current.ALSO:Nicotinic acid benzyl ester is prepared by heating nicotinic acid with benzyl alcohol in the presence of a water-entrainer, with removal of water from the system, wherein the amount of water entrainer employed is small enough to enable temperatures of 130-190 DEG  C., preferably 150-160 DEG  C., to be maintained in the reaction mixture.  Suitable water-entrainers are toluene and xylene.  It is preferable to keep the liquid surface of the reaction mixture as large as possible in which case the reaction mixture may be vigorously stirred.  The reaction may be carried out by passing a solution of nicotinic acid in benzyl alcohol from above through a heated vertical column to a water-entrainer in counter-current.  Esterification catalysts such as anhydrous zinc chloride, hydrofluoroboric acid and boric anhydride may be used in the reaction mixture.  One detailed example is given.

Filed: 1929-05-13
Abstract: 332,978. Gill, H. A., (McCartney, R. F.). May 13, 1929. Heating by electricity. - In an immersion heater comprising a core 4 bored to receive resistances 2 and housed in a metal container 1, the resistances are connected at one end of the core by a lump of solder 20. With excessive heat the solder fuses and collects in the porcelain cup 19. If the heater is removed and heated externally in an inverted position the solder again fuses and collects in the porcelain cup 21 to reconnects the ends of the resistance. The core is of steatite and is machined to fit the casing 1. The bores receiving the resistances are filled with magnesium oxide. A central bore 6 is sufficiently large to enable the interior of the element to be viewed from the outside and thus permit any glow due to overheating to be observed.

Abstract: 594,654. Wave-guides; aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 8, 1944, No. 15095. Convention date, Nov. 12, 1941. [Class 40 (v)] A radiator, particularly for ultra - high - frequencies, comprises a wave-guide with a horn flaring from the open end, two elements for producing a transverse rotating field in the guide and a circular plate facing the flared surface of the horn and spaced from it. In Fig. 1, a vertical circular waveguide 1, having a diameter greater than 0.67 of a wavelength, is terminated in a trumpet 7 having a horizontal portion 71. Transmitter 4 feeds probes 5, 6 with short-wave energy, the length of the connectors being such that the fields produced by these probes are in phase quadrature. The probes which may be dipoles or loops, are mounted in the same transverse plane at right angles to each other, and since they are excited in phase quadrature a circularly-polarized wave is produced in the guide. A circular plate 8, of metal or material having a high dielectric constant, faces the flared surface 7<1> of the guide and is spaced from it by a distance greater than a half wavelength. This results in a circularlypolarized wave being radiated equally in all horizontal directions.
