Filed: 1968-01-22
Abstract: 1,213,515. Laminated fabric. SCOTT PAPER CO. 22 Jan., 1968, No. 3356/68. Heading B5N. A process for producing a tufted composite fabric comprises uniting a substrate 11 and a layer 12 of resilient cellular material having a plurality of cell-like cavities, and tufting yarnlike material 13 through the substrate 11 and the layer 12 to form a plurality of tufts 14 extending outwardly of the surface of the -layer 12 and resiliently supported by said layer. The substrate 11 may be a woven fabric e.g. cotton, wool, rayon, nylon cotton duck, cotton percale or a tricot, or anon woven fabric or may be of plastic, rubber, or paper, and may be secured to the layer 12 by adhesive or by heat sealing or fusion. The layer 12 is preferably of open celled polyester polyurethane foam which may be reticulated, i.e. have all the cell walls ruptured, to render it flexible and permeable. The yarn-like material 13 may of twisted fibrous material or strands and may be e.g. of Orlon (R.T.M.) yarn, rayon, bi-coloured synthetic yarn, or polyester yarn. The tufts 14 which may include one or more yarns may be connected beneath the substrate 11, as shown, or may be separately adhered to the substrate 11, and their upper loops may be severed to provide free ends. The tufts may be applied to the substrate 11 and layer 12 only in certain areas, e.g. along strips, or may be spaced well apart. In this latter case the surface 15 of the layer 12 is sprayed with adhesive and decorative particulate material, which may be coloured, is applied thereto before tufting. The particulate material may be nylon flock which provides a suede-like, wear resistant surface. The composite material may be used in drapery, upholstery, clothing, or as towels, bedspreads, or floor coverings.

Title: A process for the manufacture of thermo-stable water-in-oil dispersions
IPC: A23D7/02
Filed: 1939-02-01
Abstract: Stable water-in-oil dispersions, e.g., margarine or shortenings are prepared by means of a dispersing agent made by polymerizing unsaturated oils and/or fats by heating under substantially reduced pressure and oxidizing the product by blowing at a lower temperature. Oils treated include soya, linseed, cottonseed, and sesame oils. Polymerization is preferably effected at 250-300 DEG C. maybe in presence of catalysts, e.g., iodine or chlorine; oxidation is preferably effected below 150 DEG C. with air or oxygen. The product or the polymerizate is preferably dissolved in edible oil or fat; and the product alone or thus dissolved may be refined, e.g., by steam. In an example, soya oil is maintained for 4 hours at 250-300 DEG C. and 15-20 mm. pressure whereby the iodine no. falls to 100, and is then air-blown at 100-130 DEG C. until the iodine no. is 70; the product is then dissolved in about twice its weight of refined soya or other edible oil.  Margarine is made by dissolving 2-5 per cent. of this agent in a melted mixture of cottonseed and coconut oils and dispersing therein acidified skim milk.ALSO:Margarine or shortenings are prepared by means of a dispensing agent made by polymerizing unsaturated oils and/or fats by heating under substantially reduced pressure and oxidising the product by blowing at a lower temperature.

Title: Method of extracting wax from peat and treating same
IPC: C10G73/00
Filed: 1941-03-13
Abstract: 546,937. Extracting wax from peat. REILLY, J., KELLY, D. F., and EMLYN, J. A. March 13, 1941, No. 3428. [Class 91] Wax is extracted from peat by a process which comprises digesting the peat with a solvent composed of petroleum spirit having an aromatic content of from 3 per cent. to: 40 per cent. and a boiling range lying between 30‹C. and 300‹C. in an-extraction apparatus, 'distilling. off the spirit to recover the wax, and treating the wax so obtained with spirit to separate the portion soluble at ordinary temperature from the portion soluble at boiling temperature and finally purifying the fraction soluble only in boiling spirit by treatment with activated charcoal. The preferred method of separating and purifying the less soluble wax is to dissolve the whole of the wax obtained by the extraction with petroleum spirit in boiling alcohol and then allow to cool, filter the portion which separates out, and dissolve in a further quantity of spirit and purify with activated charcoal. If desired the more soluble wax may be obtained as a byproduct by evaporation of the mother liquors of the first spirit extraction. Examples are given to show the physical constants of wax obtained as described above.

Title: Luminous product and method of making the same
IPC: H01J29/20
Filed: 1951-02-16
Abstract: 687,191. Luminescent materials. PHILCO CORPORATION. Feb. 16, 1951 [Feb. 18, 1950]. No. 3829/51. Class 39(i) A method of increasing the resistance of crystalline phosphor material to darkening in the presence of radiation comprises wetting the crystalline phosphor material with a solution of ammonium or potassium persulphate and thereafter drying the wet phosphor material. The solution of ammonium or potassium persulphate has a pH value of between about 7 and about 10. A luminescent screen can be made by permitting crystalline phosphor material of fine particle size to settle on to a substrate from a solution of ammonium or potassium persulphate, removing excess liquid from the settled phosphor material and drying the phosphor material. Binders such as potassium silicate, sodium silicate, ethyl silicate or cellulose nitrate may be used. An electrolyte such as any of the water soluble acids, bases or salts, e.g. acetic acid, ammonium hydroxide, lithium hydroxide, sodium sulphate, ammonium carbonate or barium acetate, may be incorporated in the settling medium to lower the zeta potential of the phosphor and of the substrate, and when a silicate is used as a binder, to cause it to gel. The persulphate used may serve as some or all of the electrolyte. The concentration of the persulphate in the solution may be as low as about 0.1 per cent by weight and will generally not exceed about 5 per cent, preferably not over about 3 per cent. In an example a solution is prepared comprising 64 grs. of ammonium persulphate, 75 millilitres of 14 per cent potassium silicate having a specific gravity of 1.11 and 5625 millilitres of distilled water. 2900 millilitres of this solution are mixed with 1700 milligrams of a phosphor consisting of a mixture of zinc sulphide and cadmium sulphide activated with about .01 per cent of silver. The resulting suspension is introduced into a tube blank and allowed to settle for 1 hour, after which the supernatant liquid is decanted on a vibrationless tilting table. The glass envelope is then inverted, the screen dried and the tube processed. Potassium persulphate can be used instead of ammonium persulphate and the pH value of the settling medium can be adjusted to between 7 and 10 by the addition of acetic acid. The zinc sulphide-cadmium sulphide phosphor can be replaced by one third of the weight of calcium magnesium silicate phosphor activated by titanium or by one third of the weight of a calcium tungstate phosphor.
