Patent GB-989683-A (GB)
Title: Detergent tablets and processes for manufacturing them
IPC: C11D3/37
Filed: 1962-03-27
Abstract: Detergent briquettes which disintegrate readily in water are produced by mixing together a non-ionic detergent and a normally solid water-soluble inorganic salt, producing therefrom, e.g. by spray-drying, a particulate composition containing up to 21%, most preferably 7-14%, moisture, coating the particles with 3-20% of a soluble silicate and raising the moisture content thereof to 16-25%, most preferably 17.5-20.5%, by application of (e.g. by spraying) an aqueous silicate solution, pressing the coated particles into a briquette (e.g. at a pressure of 10-100 p.s.i.), and then applying thereto 0.25-5% of a readily water-soluble organic film-forming polymer. The non-ionic detergent which most preferably comprises 7-12% of the aqueous slurry to be dried, is suitably a block copolymer of ethylene and propylene oxides, alkylene oxide condensates with alkylphenols, fatty alcohols, fatty acids and with esters and ethers of sugar alcohols but is most commonly a nonylphenoxypolyethenoxyethanol having 9-10 ethoxy groups in the molecule.  The inorganic salt generally comprises 30-75%, of which 30-50% consists of sodium tripolyphosphate and the remainder, if any, comprises sodium silicate (Na2O : SiO2 of 1 : 2.35), sodium sulphate, and sodium and potassium carbonates. In addition, such anionic detergents as sodium alkylbenzene sulphonate, alkyl sulphate, fatty acid monoglyceride sulphate, and N-acyl-N-methyl tauride in which the alkyl or acyl groups contain 12-15 carbon atoms in amounts of 1-5%, and C12- 18-alkanols in amounts of 0.5-5% may also be included.  The silicate solution with which the particles are sprayed preferably consists of a 25-46%, preferably a 35-37%, solution of a sodium silicate (Na2O : SiO2 of 1 : 2-1 : 3, preferably 1 : 2.35) and the coated particles preferably have diameters in the range 0.25-4 mm. After this coating, the particles are preferably treated with a talc which passes a 200 mesh (U.S.S.) sieve in a amount of 0.5-5%, and are then screened to pass a 6-60 mesh before being compacted into a briquette.  The water-soluble polymer coating applied to the briquette may comprise polyvinylpyrrolidone, sodium carboxymethyl cellulose, or hydroxypropylmethylcellulose, but preferably consists of a polyvinyl alcohol having a weight average degree of polymerization of 30-300 and which contains 10-30% polyvinyl acetate; the polymer is suitably applied by spraying as a 10-25% solution to yield 0.25-1% polymer on the final tablet (average coating thickness of 0.01-0.8 mm.). The polymer solution to be sprayed may contain sodium bicarbonate, ethylene glycol or sorbitol.  The final briquettes may be packed in moisture-proof bags or sleeves, e.g. of polyethylene.

Abstract: 815,114. Tubular heat exchangers. BRITISH THOMSON - HOUSTON CO. Ltd. April 16, 1957 [April 18, 1956], No. 11813/56. Class 64(3) A cooling device comprises a first duct through which a fluid to be cooled will be passed, and a second duct for conveying a cooling fluid in heat transfer relationship with fluid in the first duct over a given length of the latter, which ducts are separated over said length by a wall thickness selected in dependence on that length and on a contemplated rate of heat extraction from the fluid to be cooled to give a thermal resistance appropriate to providing through the wall a temperature drop at least as great as the difference between the average temperature over said length of the fluid to be cooled and a (lower) maximum temperature above which the cooling fluid should not rise as a result of the heat exchange between it and the fluid to be cooled. In the form shown, liquid bismuth flowing through a duct 1 is cooled by water passing in contraflow through a jacket 3 surrounding a length l of the duct, the wall portion of the duct which is embraced by the jacket being of increased thickness as shown and such that the collant does not vaporize in flowing through the jacket. The duct may be made of stainless steel or chromeiron and the jacket may be of copper shrunk or otherwise secured to the duct. Alternatively the jacket may be integral with the duct. A blow-off valve 6 may be provided for the jacket and may actuate an audible or other warning device. Monitoring arrangements may be provided to control, e.g. through mechanically or otherwise actuated valves, the flow of either or both fluids to maintain specified temperature conditions and, should the temperature of either fluid approach a critical value, either to give a warning or to switch off the equipment in which the cooling device is being used.

Title: Method of supervising and controlling the course of the reaction in the oxygen top blowing process
IPC: C21C5/46
Filed: 1965-03-22
Abstract: The course of the reaction during an oxygen top-blowing process is controlled from the electrical conductivity determined between the electrically insulated lance, or a separate charge level indicator, and the metal bath.  Before blowing, the level of the bath surface may be determined by lowering the lance which may comprise an extension electrically connected thereto, and then the distance between the nozzle and the bath surface adjusted. The variation in the conductivity may be used for automatically controlling this distance, the amount of oxygen blown on, and the start and end of the blowing and of the addition of flux.  Two or more resistance measuring ranges may be adapted to the particular conductivity used. The process may be effected in a converter or a rotary Kaldo furnace, and is suitable for converting pig iron rich in phosphorous, wherein silicon is optionally added at the start of blowing.
