Patent GB-386328-A (GB)
Title: Preparation of compositions containing synthetic resins and soluble alginates
IPC: C08L61/24
Filed: 1931-04-02
Abstract: Mixtures of water-insoluble urea or thiourea formaldehyde condensation products free from strong acids with water-soluble salts of alginic acid such as sodium, potassium, ammonium or magnesium alginate or double alginates of metals and ammonia yield compositions capable of forming stable solutions and non-crazing films.  The compounds may be mixed dry or in aqueous solution and in the latter case they may be carefully dried.  The condensation product is preferably one containing excess of the basic component, i.e. urea or thiourea.  Accelerators which do not coagulate or precipitate the algin as acid or salt may be added to the mixture.  Organic acids, such as acetic, tannic, formic, benzoic, butyric or succinic acids ; boracic or carbolic acid ; potassium hydrogen sulphate ; acidic salts of magnesium or manganese such as sulphates or chlorides or salts of metals of lower atomic weight than that of magnesium may be used as accelerators.  In examples, (1) a resin syrup prepared by condensing urea with formaldehyde is mixed with a solution of sodium alginate and, if desired, neutralized with an acid or acid salt such as potassium acid sulphate when required for use. Solutions thus prepared may be used as varnishes or paint vehicles with or without inert ingredients such as pigments, fibrous or other fillers, accelerators being used at the time of use.  (2) The liquid composition of claim 1 may be dried to yield a readily water soluble powder which may be mixed with a dry accelerator, colours or fillers. A suitable filler is a soluble alkaline silicate.  The product may be used as a size for fabrics, a wood or fibre impregnation agent, a stain or distemper for a plaster face or a solid water paint.ALSO:Mixtures of water-soluble urea- or thiourea-formaldehyde condensation products free from strong acids and water-soluble salts of alginic acid such as sodium, potassium, ammonium and magnesium, alginates or double alginates of metals with ammonia yield compositions capable of forming, with or without the addition of accelerators which do not coagulate or precipitate alginic acid, stable solutions which may be used as distempers or paint vehicles. Suitable accelerators are organic acids such as acetic, tannic, formic, benzoic, butyric or succinic acids; boracic or carbolic acid; potassium hydrogen sulphate; acidic salts of magnesium or manganese such as sulphates or chlorides; salts of metals of lower atomic weight than manganese.  A suitable filler is a soluble alkaline silicate.ALSO:Mixtures of water-soluble urea- or thioureaformaldehyde condensation products free from strong acids and water-soluble salts of alginic acid such as potassium, ammonium, sodium or magnesium alginates or double alginates of metals and ammonia yield compositions capable of yielding, with or without the addition of accelerators which do not precipitate or coagulate alginic acid, a sizing agent for fabrics.

Title: Process of mechanically rendering starch capable of swelling in cold water
IPC: C08B30/14
Filed: 1957-03-29
Abstract: 863,575. Cold-swelling starch. MEIJER'S FABRIEKEN VOOR VERPAKTE ARTIKELEN N.V., O.J. March 29, 1957, No. 10423/57. Class 2(2). Starch products capable of swelling in cold water are made by increasing the particle size to at least twice its original value, in the presence of moisture, by shear action at a linear pressure of 100 to 50,000 kg./cm. and at a temperature below the gelatinization point of the starch. A suitable apparatus is an edge runner mill, with either rotating or stationary tray, the traversing wheels of which may or may not be under extra pressure. A ball mill may also be used at a speed at least twice that used for grinding purposes. The desired particle size can be selected by subsequent grinding and sieving. The swelling capacity of the products can be improved by addition of substances which promote the gelatinization of starch, such as soda ash, caustic soda, or alkali metal nitrates before or during the treatment. Borax may be added to prevent the formation of lumps during dissolution of the starch. The starch products obtained may be subsequently decomposed by enzymatic action.

Abstract: 542,006. Luminescent materials. KODAK, Ltd. (Eastman Kodak Co.). June 17, 1940, No. 10470. [Class 39 (i)] Chrysene is added to a paint to make it fluorescent ; the chrysene may contain up to 1/30th of its weight of naphthacene. The chrysene is added to a vehicle such as gum arabic, a disperser, and glycerine ; or to linseed oil or dammar varnish. To prepare the fluorescent material commercial chrysene is dissolved in boiling naphtha a decolourizing carbon added and the chrysene crystallized out ; if a violet fluorescene is desired 5 per cent of maleic anhydride is added to the chrysene and boiled for 15 minutes. If green or blue-green fluorescene is required naphthacene is added to the chrysene in stated amounts. The chrysene so prepared is washed with methanol and.dried. The chrysene is then ground preferably with the vehicle used for addition to the paint; a process and quantities is described using a water solution containing gum arabic, phenol, glycerine, a dispersing agent called Darvan to which more gum arabic is added after grinding. Colour pigments non fluorescent are added. The materials as described are particularly useful in the photo mechanical processes described in the U.S.A. Specifications 2,008,290 and 2,108,503.

Abstract: 384,531. Gramophone pich-ups. PAILLARD ET CIE SOC. ANON., E., Ste-Croix, Switzerland. April 15, 1932, No. 10819. Convention date, April 22, 1931. [Class 40 (iv).] In order to minimize tracking error as the needle of a gramophone pick-up passes across the record, instead of fixing the pickup at an inclination to the carrying-arms the pickup itself is so constructed that the vertical plane passing through the axis of oscillation of the armature forms an angle other than 90‹ with the plane of the magnetic circuit. With this arrangement, the pick-up can be fixed to the carrying-arm with it body normal to the arm. In the construction shown, the polepieces 12, 13 of the magnet 11 are so formed that the air gap between them is inclined to the plane of the magnet, Fig. 4. The armature 14, which is of square section, is mounted within a surrounding mass of rubber in the air gap so that the armature is thus virtually pivoted on an axis inclined to the plane of the magnet.
