Abstract: 1,245,005. Transparent spinel- CORNING GLASS WORKS. 9 Oct., 1968 [9 Oct., 1967] No. 47835/68. Heading ClA. A process for the preparation of polycrystalline magnesium aluminate spinel bodies with excess magnesia having improved in line transmittance of radiation comprises sintering a preformed green body of a pulverulent intimate mixture of the spinel and an amount of magnesium oxide of up to approximately 0À35 mols. of oxide per mol. of spinel said sintering being effected at a temperature of from 1500‹ to 1900‹ C. in a vacuum or in a hydrogen atmosphere. The invention also comprises a sintered polycrystalline body consisting essentially of magnesium aluminate spinel and excess magnesia the excess magnesia being present in an amount sufficient to enhance the in line transmittance of the spinel for radiation at each wavelength in the range of from 0À4 to 0À5  microns but not being present in an amount over 0À35 mol. of magnesia per mol. of spinel. Maximum transmittance is obtained when no more than 0À04 mols. of excess magnesium oxide is present. The sintering is preferably carried out at 1500‹ to 1900‹ C. in vacuum or in a hydrogen atmosphere. The mixture of spinel and excess magnesium oxide can be made by melting ammonium aluminium sulphate dodecahydrate with magnesium nitrate hexahydrate, heating to drive off water and calcining. Aluminium sulphate and magnesium acetate or chloride can be used similarly. Alternatively, a sinterable spinel (stoichiometric) powder can be mixed with a water or methanol solution of magnesium nitrate and the product be dried and heated.

Abstract: 1,208,613. Fuel elements. NUCLEAR POWER GROUP Ltd. 25 Oct., 1968 [8 Nov., 1967], No. 50890/67. Heading G6C. A fuel element string has a guide member 3 at its lower end and a brush-type seal 4 mounted in a recess in the member 3. The seal 4 may consist of metal fibres or wires embedded in a metal ring and must be capable of flexing in the manner of a brush so that it can deflect to pass any projection in the bore 1 of a graphite moderator core in which it is located. Although only one seal has been shown, two or more such seals may be spaced along the axial length of the fuel element string. Flexible membranes may be included between pairs of brush-type seals to improve the sealing properties. The fuel element string comprises graphite sleeves 2 which house fuel-containing members (not shown) and are spigotted together to form a flexible string which may be lowered into or withdrawn from the bore 1 in known manner whilst the reactor is on load. The seal helps to centralize the string in the bore and reduces the velocity of cooling fluid in the annular space between the sleeves 2 and the wall of the bore. As a result, vibrations set up by forces due to fluid pressure during insertion and withdrawal of the string are kept to a minimum.
