Title: Improvements in waterproof compositions
IPC: C08L91/00
Filed: 1945-07-26
Abstract: Compositions for use in road and building construction comprise mixtures of heavy metal and/or alkaline earth metal soaps of fatty acids, heavy metal and/or alkaline earth metal soaps of resin acids, neutral hydrophobic substances, such as bitumen, fats, or waxes, and fillers.  The soaps used may be those of calcium, zinc, lead, iron, or manganese, and the fatty and resin acids may be saponified separately or together.  The material known as Swedish liquid rosin (a mixture of fatty and resin acids) may be used; alternatively, vegetable pitches, residues from the distillation of oils, or animal residues such as wool grease, and rosin pitch, which contain unsaponifiable materials and so eliminate the need for the addition of a neutral substance, may be used.  The filler may be a diatomaceous earth.  Pigments may also be added.

Title: Improvements in process for manufacturing and purifying alumina
IPC: C01F7/164
Filed: 1928-07-03
Abstract: 293,392. Seailles, J. C. July 5, 1927, [Convention date]. Sodium aluminate; alumina.-In the process for the manufacture of alumina, as described in Specifications 277,697 and 283,509, from non-halogenated aluminium ores, the proportion of silica in the alkaline-earth aluminate obtained by the use of an autoclave, and capable of dissolving on the subsequent treatment with sodium carbonate, thus forming an undesirable impurity, may be reduced by regulating the temperature, pressure and duration of heating in the autoclave, without reducing the quantity of aluminate extracted from the bauxite by an excessive amount. A further improvement is gained, when lime is used for treatment of the bauxite, by the employment of catalysts forming soluble compounds with lime, which are decomposed by alumina. Such catalysts are sulphonated organic derivatives, such as benzene sulphonic acid, sulpho-ricinoleic acid, and the like. The bauxite may also be treated previous to extraction in a colloid mill or similar apparatus. The sodium aluminate bath, containing some dissolved silica, may be further purified by preventing all excess of free alkali when the alkaline-earth aluminate is treated with sodium carbonate. This may be carried out in several ways. For example, when tetracalcium aluminate is produced in the autoclave, the subsequent reaction with sodium carbonate is as follows : 2(Al2O3.4CaO)+8Na2CO3+5H2O.=2(Al2O3.3Na2O.) +8CaCO3+10NaOH. The free alkali may be diminished by washing the crude aluminate with water, thus dissolving some of the lime, so that the amount of free alkali will be reduced in proportion to the amount of calcium carbonate to be produced, equilibrium being reached when 2¢ molecules of lime have been removed from the calcium aluminate. A similar effect is produced by treating the crude aluminate with sufficient carbonic acid to convert 2¢ molecules of lime to the carbonate. Either or both of the above processes may be further combined with treatment by sodium bicarbonate to obviate or reduce the free alkali in the solution. A further purifying process, which may be used in conjunction with those previously described, consists in the addition of calcium aluminates to the sodium aluminate solution containing dissolved silica. A double decomposition occurs, with the precipitation of the greater part of the silica. About 10 per cent of calcium aluminate is added to the solution and may consist of the crude aluminate discharged from the autoclave. By this means the amount of silica present may be reduced from 3.02 to 0.16 per cent. In practice, known methods of exhaustion may be used, systematically employing this purifying effect, or alternatively, a cyclic or continuous process may be used. The proportions of the compounds employed may be modified during the first operations, but subsequently an equilibrium is established from which there are no appreciable variations.

Title: Improvements in or relating to electroplating
IPC: C25D3/60
Filed: 1965-05-07
Abstract: A tin-bismuth alloy having a high resistance to tin pest is cathodically deposited on a basis metal from an aqueous bath containing alkali metal stannate, free alkali metal hydroxide, and a hydroxyalkyl bismuthate, preferably in a concentration representing 0.05 to 1.5 g/l Bi.  Preferably the alkali metal employed is potassium.  The hydroxyalkyl bismuthate may be any of those formed by reacting equimolecular proportions of sodium bismuthate and ethylene glycol, propylene glycol, glycerol, erythritol, arabitol, sorbitol, dulcitol, mannitol, or the diol, triol, pentanol, or hexol of cyclohexane.  Plating is effected with a C.D. of 1 to 40 amp./dm2 at 60 DEG C. to the bath boiling point, e.g. 105 DEG C., using insoluble or soluble e.g. tin or Sn-Al alloy anodes.  With insoluble anodes the bath composition may be maintained by adding a composition comprising the bismuthate and an alkaline oxide tin sol as in Specification 1,109,676.  The binary alloy deposit typically contains 0.1 to 0.6% by weight bismuth. Basis metals coated are steel, brass, bronze or copper, e.g. pipe or coupling threads or copper wire.ALSO:A hydroxy alkyl bismuthate is prepared by slowly adding with stirring to a polyhydric alcohol (optionally in sufficient water to effect solution) an equimolecular proportion of an alkali metal bismuthate, e.g. sodium bismuthate, and maintaining the temperature in the range 55 DEG  to 80 DEG  C.  The reaction mixture is allowed to cool, the resulting free sodium hydroxide is neutralized with specified organic acids, and the mixture is then poured into ethyl alcohol when the bismuth compound forms a dense flocculent precipitate.  After filtration the precipitate is redissolved in water and again precipitated with ethyl alcohol and this treatment is repeated. After drying at 100 DEG  C. a heavy powder formed of transparent amber or brown scales is obtained. Typical polyhydric alcohols employed are ethylene or propylene glycol, glycerol, erythritol, arabitol, sorbitol, dulcitol, mannitol, or the diol triol, pentol, or hexol of cyclohexane. Dihydroxypropyl-, trihydroxybutyl -, pentahydroxyhexyl - and pentahydroxycyclohexyl-bismuthate esters are described.

Title: Aqueous solutions of silver hydroxyfluoborate and separation of hydrocarbons using same
IPC: C01G5/00
Filed: 1964-05-11
Abstract: Fluid mixtures of saturated and unsaturated hydrocarbons or of unsaturated hydrocarbons differing in absorptivity are separated by contacting the mixture with an aqueous solution of silver hydroxyfluoborate, AgBF3OH, and recovering the absorbed unsaturated hydrocarbon(s) from the aqueous solution.  The AgBF3OH solution may contain HBF3OH. Aliphatic and alicyclic hydrocarbons may be separated from olefins, diolefins, aromatic hydrocarbons and cyclic olefins. Unsaturated hydrocarbons which form reversible solid complexes with AgBF3OH, e.g. conjugated diolefins, can be separated from other unsaturated hydrocarbons.  In examples benzene is separated from cyclohexane and ethylene from ethane.ALSO:An aqueous solution of silver hydroxyfluoborate, AgBF3OH, is produced by reacting a silver salt, oxide or hydroxide with excess HBF3OH in aqueous solution. Ag2CO3 is the preferred salt.  The solution, with the optional addition of HBF3OH, is used to separate fluid mixtures of saturated and unsaturated hydrocarbons or of unsaturated hydrocarbons differing in absorptivity.

A vibrator comprises a rotor 1 having a plurality of axially spaced radial bores 6, in each of which a ball 7 is located, and a housing formed with two internal surface cams 5, each of which progressively increases in height from one end to the other to terminate in a step. On rotation of the rotor 1 each ball 7 under centrifugal force rolls on the cam surfaces to be forced back thereby into its bore until it reaches the step at the end of a cam surface where it flies out and strikes the housing. The bores 6 are angularly spaced from one another. The rotor has end spigots 2, 3 adapted to be mounted in bearings, a drive being connected to the spigot 3. A rod or pin may extend freely through the housing at a point beyond the step to transmit further vibrations to a plate or other surface. The housing may be formed by abutting two metal bars, turning them to cylindrical shape about an axis at the junction of their abutting faces, boring a cylinder about an axis displaced with respect to the turning axis along the junction of the abutting faces, separating the two parts and finally reversing the relative positions to provide a cylinder with two internal surface cams.
