Title: Improvements in or relating to organosols
IPC: B01J13/00
Filed: 1962-08-08
Abstract: A stable, anhydrous organosol comprises a water-immiscible, non-polar organic medium having dispersed therein colloidal particles of a water-insoluble inorganic oxide and organophilic counter ions associated with the oxide particles by attraction of charges there between, the counter ions having a molecular weight of at least 100 and an aliphatic chain of at least six carbon atoms.  The organosol is produced by agitating an aqueous sol of the inorganic oxide with the organic medium containing an organophilic transfer compound, which does not ionize in the organic medium but in the medium of the aqueous sol to form the counter ions, and recovering the organic layer containing the inorganic oxide particles.  Specified inorganic oxides are silica, chromia, magnesium oxide, lead sesquioxide, kaolin.  The organic medium may be any liquid hydrocarbon, or mixtures thereof, e.g. xylene, kerosene, gasoline, benzene, motor-oil, fuel oil, pentene, styrene, and also 3-pentanone and ether.  The organophilic transfer compound may be a quarternary amine, organo-sulfuric acid, carboxylic acid, phosphoric acid and salts thereof. Naphthenic acids, oleic acid, heptadecyl sulfonic acid and di-2-ethylhexyl phosphoric acid are also specified as transfer compounds.  The particular transfer compound used is dependent upon the surface charge of the inorganic oxide particles of the aqueous sol.  The latter charge may be reversed by using a complexing agent, e.g. a salt of a hexametaphosphoric or tripolyphosphoric acid.  A liquid monomer capable of being polymerized to form a solid matrix containing the dispersed sol particles may also be used as the organic medium, e.g. vinyl chloride, vinyl acetate, vinyl alcohol, and olefins.  Mixtures of monomers which form co-polymers on polymerization may also be used.  Specific examples relate to (1) a silica organosol having an organic medium comprising iso-octane, n-heptane and isodecanol, the transfer agent used being tricaprylyl monomethyl ammonium chloride, (2) a chromia sol in xylene, the ammonium salt of di-2-ethylhexyl phosphoric acid being used as transfer agent, (4) lead sesquinoxide in gasoline, ammonium oleate being used as the transfer agent, (5) chromia in styrene, ammonium di-2-ethylhexylphosphate being used as transfer agent, (6) magnesium oxide in fuel oil, di-2-ethylhexylphosphoric acid being used as transfer agent and kaolin in fuel oil, di-2-ethyl-hexylphosphoric acid being used as transfer agent. Specifications 450,308, 450,309, 557,414, 924,999, 968,202 and 976,328 are referred to.ALSO:Polystyrene containing colloidal chromium oxide particles is prepared by transferring said particles from an aqueous sol thereof to styrene using ammonium di-2-ethylhexyl phosphate as the transfer agent, and polymerizing the styrene by heating to 60 DEG  C. with benzoyl peroxide.  Specifications 450,308, 450,309, 557,414, 924,999, 968,202 and 976,328 are referred to.

Abstract: 436,561. Filing papers. SHANNON, Ltd., Shannon Corner, New Malden, Surrey. Oct. 23, 1934, No. 30422. Convention date, June 1. [Class 146 (i)] In a file in which the documents are filed on bendable members and held down by a bar passing over these members and provided with slides for securing the ends of the members when turned down upon the bar, the bar is provided with further members which can be turned down to lie lengthwise of the face of the bar clear of the filed documents in a similar manner to the bendable filing-members, or may be turned into an upright position so that they may receive documents from the file when the bar is inverted. The members 5, preferably of flattened tubular shape, are hinged to the locking-bar 1 close to the apertures which are adapted to pass the flexible filing-members 4, so that when the bar is in its normal position the members 4 may be passed up through the apertures and into the members 5, which may then be folded down to lie along the bar 1, and clamped in position by the sliders 2. When it is desired to remove a sheet from the middle of the pile, the locking-bar is reversed, as shown, and the members 5 pushed over the members 4, into the holes in the sheets 6, so that they act as transfer posts for the upper portion of the pile.

Abstract: 1,167,819. Truing grinding wheels. CIMAT S.p.A. 27 June, 1968 [30 June, 1967], No. 30712/68. Heading B3D. A method of dressing a generally cylindrical grinding wheel 3 to form a predetermined concave profile thereon comprises rotating the grinding wheel about its axis and moving it in a longitudinal direction parallel to its axis, supporting a tool 5 for movement into and out of engagement with the wheel in a transverse direction perpendicular to the longitudinal direction of the wheel, the transverse movement being controlled by a linear cam 21 which is inclined to the longitudinal direction and effects rocking movement of an eccentric cam 14 in dependence on the movement of the workpiece, the cam 14, in turn, moving a carriage 8 supporting the tool in the transverse direction. The tool, such as a diamond, is mounted in a tubular holder 6 carried by the carriage 8 and is movable about a horizontal pivot on the carriage between operative and inoperative positions. The carriage is mounted by leaf-springs 9 on a support structure 10 having bearings for a shaft 15 on which the eccentric cam 14 is secured. The cam has a hardened insert 14a engaging a roller 13 carried by the carriage to effect movement thereof upon rotation of the cam. Rotation of the cam is effected by a roller 20 which is mounted on a lever 17 secured to shaft 15 and is urged by a spring 18 into engagement with the linear cam 21 which is movable longitudinally with the grinding wheel whereby the tool 5 forms a concave profile on the grinding wheel which is used to form a convex surface on the inner track surface of the outer race of a conical or cylindrical roller bearing. In another embodiment, the linear cam is formed as a sector-shaped member 25 adjustable in an arcuate recess in a plate 22 by push-rods 33, 34 and screws 33a, 34a to vary the inclination of the cam surface 31 which has a hardened insert 26.

The Figure shows a piece of germanium 1 and closely adjacent contact members 2 of aluminium and gold 20 microns apart embedded in an insulating substance 3 such as a silicone resin. Electrical leads 4 extend through the insulating substance and connection is made to the contact members by conductive layers 5 which may be deposited by vacuum deposition, spraying, chemically or electro-chemically or by any combination of such method. The insulating layer 3 may initially cover the transistor entirely. In which case part of the surface of each electrode is exposed before the deposition of layer 5.

Abstract: 1,073,932. Moulding plastic materials. LABORATORIO PIERO MODIGLIANI S.R.L. July 20, 1965, No. 30874/65. Heading B5A. [Also in Division D1] Panels or sheets of fibre glass reinforced polyurethane are produced by pulling a web of glass fibres, in which the fibres are substantially transverse the web, from a roll 1 and thereby causing a considerable expansion in web thickness, and feeding the expanded web together with upper and lower layers 4, 4 of glas gauze between conveyer belts 6, 6<SP>1</SP> where the fibres are sprayed with a polyurethane foam which extends throughout the web thickness and quickly sets. Sheets of corrugated form may be produced by shaping the belts or by providing movable moulds at the outlet end of the belts. The expanded web between the layers 4, 4<SP>1</SP> may be reinforced by fibre cords arranged longitudinally, transversely and in zig-zag fashion, some of which cords may protrude from the sides, ends or surfaces of the formed panel providing ,tufts which assist in the joining of adjacent panels together. By slightly lifting longitudinally arranged reinforcing cords located adjacent the lower surface of the web during the foam setting period, the glass fibres may take up a sinuous form in the transverse direction of the web.
