Title: Improvements relating to thorium dioxide sols
IPC: B01J13/00
Filed: 1931-10-15
Abstract: Thorium dioxide sols, which are positively charged, are rendered insensitive to change of reaction by the addition of a colloidal or semicolloidal carbohydrate, such as amylose or similar degradation products of starch.  The stabilized sols may be rendered neutral or alkaline, and may be used for radiographic diagnosis, especially for the mere filling of hollow spaces and capillaries, such as the bladder and kidneys.  According to examples: (1) Into 100 parts of a 12.5 per cent thorium dioxide sol there are introduced 10 parts of an amylose prepared by digesting 10 parts of rice starch with 2.5 parts of oxalic acid and 50 parts of water in an autoclave at 115-120 DEG C. for 4 hours. The homogeneous solution is dialysed and evaporated. (2) To prepare a sol of high concentration which is stable for all pH values, 20 parts of a strongly degraded amylose are added to 100 parts of a 25 per cent thorium dioxide sol.  The amylose is prepared by treating 10 parts of wheat starch in 100 parts of water with 3 parts of a 3 per cent solution of diastase at 50 DEG  C. until a thin liquid is produced.ALSO:Thorium dioxide sols which may be used for radiographic diagnosis are rendered insensitive to change of reaction by the addition of a colloidal or semicolloidal carbohydrate, such as amylose or similar degradation products of starch.

Title: Improvements relating to smoking tobacco
Inventor: KILBURN KEITH DOUGLAS
IPC: A24B15/30
Filed: 1966-06-30
Abstract: The characteristic flavour of the smoke of a tobacco is modified or improved by adding to the tobacco an organic nitrile which is volatilisable under the influence of the heat produced on the smoking of the tobacco or a relatively involatile compound which is decomposable to yield the nitrile under the influence of the said heat.  Suitable nitriles include those of general formula CnH2n+1.CN, where n is an integer from 3 to 14, such as n-valeronitrile, n-non-anonitrile and dodecanonitrile, and a -b  unsaturated nitriles of general formula R.CH:CH.CN where R is any normal, iso-or tertiary alkyl, cycloalkyl or aralkyl radical having from 1 to 9 carbon atoms, such as trans-crotononitrile.  Suitable involatile compounds are cyanohydrins or cyano esters of mono- or di carboxylic acids, which yield an a -b  unsaturated nitrile under the influence of heat.  The nitriles may be added to cut tobacco by spraying, dipping or incorporation in a humectant, or by the method of evaporation from a heated wick.

Title: Improvements in or relating to organosiloxane compositions
Filed: 1960-08-26
Abstract: A silicone rubber stock comprises (1) 100 parts by weight of an organopolysiloxane having an average of from 1,9 to 2,01 inclusive methyl, phenyl, vinyl or 3,3,3-trifluoropropyl radicals per silicon atom, at least 25% of the radicals being methyl radicals and the organopolysiloxane having a viscosity of at least 500 cs. at 25 DEG C. and (2) from 1 to 10 parts by weight of indanthrene blue, phthalocyanine, a chelated metal complex of phthalocyanine, or terphenyl.  The compositions may contain inorganic fillers, e.g. silicus (native, precipitated, fume and raerogels), carbon black, metal oxides and silicates, low viscosity hydroxylated siloxanes and other conventional additives. The compositions may be vulcanized with, for example ditertiary butyl peroxide, sulphur or an orthosilicate or polysilicate such as methyl silicate and a catalyst such as dibutylt in diacetate, lead octoate or methylamine.  The vulcanizing agent and filler are preferably used in amounts of from 1 to 10 and to 300 parts by weight respectively per 100 parts of organopolysiloxane.  In a typical example 100 parts of a phenylmethylpolysiloxane gum, 3 parts of indanthrene blue, 30 parts of fume silica, 8 parts of a 50 cs. hydroxylated dimethylpolysiloxane and 5,6 parts of dibenzoyl peroxide were milled and cured for 5 minutes at 125 DEG  to 135 DEG C.  The resistance of the resulting elastomer at 200 DEG C. to radiation from a cobalt-60 source is compared with that of an elastomer prepared from a similar composition which contains no indanthrene blue.  The elastomers may be used under conditions of high temperature and high radiation intensity, for example as electrical insulation or as gaskets. Specification 883,266 is referred to.

A composite paper &c. tube, particularly for catamenial appliances, comprising two tubes in telescoping relation is made by winding helically on a mandrel a plurality of strips some of which are moistened and coated with adhesive to form an inner tube, and winding helically thereon a further plurality of strips some of which are coated with adhesive to form an outer tube, the inner strips being wound under a greater tension than the outer strips or have a greater moisture content than the outer strips so that, when the tubes are cut and dried, the relative shrinkage of the tubes is such that the inner tube is a frictiontight but slidable fit in the outer tube. The inner strips 6, 7, 8 and the outer strips 9, 10, 11 are fed over guide bars on a pair of supports 2 to a mandrel 1 on which they are wound by an endless belt 3.
