Patent GB-820584-A (GB)
Title: Radioactive tracer
IPC: G21H5/02
Filed: 1957-02-15
Abstract: Porous hydrocarbon conversion catalysts in finely-divided form are coated with radioactive gold both inside the pores and on the surface to serve as tracers.  Examples of such catalysts are alumina, 87% : 13% silica-alumina, aluminium silicate, silica gel, fuller's earth and diatomaceous earth.  They may also serve as carriers for active metals such as platinum, cobalt and molybdenum.ALSO:The ability of a grease filter to remove fine particles is measured by a radioactive tracer technique in which fine particles are coated with radioactive gold, mixed with grease and the grease then filtered.  Comparison of the radioactivity of the grease before and after filtration indicates the efficiency of the filter.  Where the radioactivity is measured by particle counting the effectiveness or otherwise of some areas may be investigated (e.g. in a stacked-plate filter).ALSO:A radioactive tracer is composed of finely-divided material coated on its surface and/or in its pores with radioactive gold. The tracer may be produced in two ways:-(1) by mixing the material with an aqueous solution of a reducible compound of naturally-occurring gold (Au197), e.g. auric chloride, bromide, cyanide, sulphate or hydrogen nitrate, which preferably contains a reducing agent such as oxalic acid, hydroquinone, p-amino-phenol, pyrogallol, catechol or sodium bisulphite, reducing the compound to deposit gold by heating at 200 DEG -1200 DEG F., and finally irradiating with slow neutrons to convert at least part of the Au197 to the radioactive isotope Au198; or (2) by first irradiating the reducible compound of gold and then coating as in (1).  The finely-divided material may have a particle size of up to 2000 microns and preferably comprises elements having low neutron capture cross-sections, e.g. C, O, Si, Al, Be, P and F. The tracer may be used to evaluate the efficiency of a grease filler (see Group I), and in catalytic cracking processes.  Porous hydrocarbon conversion catalysts which may be coated with radioactive gold to serve as tracers are alumina, 87%:13% silica-alumina, aluminium silicate, silica gel, fuller's earth and diatomaceous earth: these catalysts may serve as carriers for active metals and should be coated with the gold both inside the pores and on the exterior.  Other materials which may be used as tracers include rock dust and organic polymers and gels.

[Also in Group XVI] A method of producing a roll body having a compact uniform covering comprises the steps of impregnating an unwoven fibrous sheet material consisting of 10 to 60% by weight of fibres of low elongation and 90 to 40% by weight of fibres of high elongation, with an aqueous natural or synthetic latex composition in such amounts until 20 to 70% by weight of said latex, based on the total fibre weight, is incorporated into the sheet material, drying the thus impregnated sheet material substantially without curing, arranging layers of the dry impregnated sheet material axially along a mandrel, pressing said layers axially on said mandrel until the thickness of each layer has been reduced to about “ to 1/6 of the original thickness and subjecting the layers in the compressed condition to heat for about 4 to 8 hours. Suitable adhesives are vulcanizable compositions of natural and synthetic rubbers and rubber-like substances and elastomers such as silicone rubbers, polyurethanes and modified epoxy resins and methacrylic acid esters. The impregnating compositions may also contain reinforcing agents which improve the effect of the adhesive by cross-linking or otherwise, such as reactive incompletely condensed precondensates of aldehydes and/or ketones, reactive amino- and/or phenoplasts or reactive precondensates of aldehydes and/or ketones with phenols or amino compounds such as urea, dicyano-diamide, guanidine, triamines; also ethoxyline resins, polyester resins, polycarbonate resins, polyamide resins, isocyanates and vinyl resins. The fibres may be natural vegetable or animal fibres and/or synthetic or semi-synthetic fibres. The fibres of low elongation may be bast, stretched polyamide or polyester fibres, polyvinylidene, chloride, highly stretched polyvinyl chloride or highly stretched cellulosic filaments. The fibres of relatively high elongation may be e.g. wool staple fibres, regenerated cellulose fibres or unstretched polyvinyl chloride fibres. The reinforcing agents, instead of being incorporated in the adhesive, may be applied to the impregnated web by an after-treatment. The fibrous material may be in the form of a fleece or web obtained by carding or puffing which may contain the fibres in superposed layers in intercrossing directions. Impregnation may be effected by dipping or by applying the impregnant in the form of a foam. The finished rolls may be used as counter or lasting rolls in roller embossing operations for textiles, leathers, or paper.
