Title: Autogenously reactive minute polymer capsules
IPC: C09J5/00
Filed: 1966-12-01
Abstract: A capsule containing a liquid curable resin and curing agent which are mixed when the capsule is crushed for use as an adhesive or sealant, is formed by encapsulating the resin by phase separation in polymeric material and adhering the agent in particulate form to the exterior of the capsule wall.  The liquid resin may be a polysulphide, a polyepoxide or a polyisocyanate polymeric material. Curing agents for polysulphides may be dioxides of tellurium, manganese or lead or antimony trioxide.  A corrosion inhibitor such as a chromate of strontium, barium or zinc, or zinc yellow may be mixed in the resin.  In one method of forming the capsules, pigskin gelatine and gu arabic are dissolved in water and the pH adjusted to 4.5. Polysulphide resin is added with stirring and pentandiol solution added.  Resultant capsules are dispersed in anhydrous 2-methyl-2,4-pentandiol and the capsules dried and rinsed.  They are then shaken with particulate tellurium dioxide so as to be coated with this powder.  Reference has been directed by the Comptroller to Specification 902,061.

Abstract: 1378857 Treating castings INSTITUTUL DE CERCETARI METALURGICE 23 Nov 1971 [23 Nov 1970] 54431/71 Heading B3F [Also in Division H1] When casting ingots of killed or non-killed steel temperature measurements are made upon the cast ingot at the following points 50-100 mm. below the lower boundary of the feeder head (hot-top). (a) Centrally of one face of the ingot at point 1 which is spaced inwardly of the ingot sidewall surface by a distance equal to the minimum solid skin thickness required to enable the cast ingot to be stripped from its mould; (b) at point 2 centrally of the ingot's horizontal cross-section; (c) at point 3 nearer to the ingot sidewall surface than point 1 and; (d) at point 4 spaced <SP>1</SP>/ 6 th of the way along the diagonal of the ingot's horizontal cross-section as measured from the ingot's corner. If killed steel is being cast, the ingot is stripped from the mould when the measured temperature at point 2 indicates that the ingot is completely solid. With unkilled steel, when the measured temperature at point 1 indicates that a solid metal shell of sufficient thickness has been formed, the cast ingot is stripped from its mould. Temperature measurements are continued after the ingot has been stripped and from them is calculated an estimate of the ingot heat content. The estimate is employed to determine the optimum time that the ingot should be left in a reheating furnace before rolling. The temperature measurements are made by thermocouples protected by sheaths comprising at least two layers of steel with refractory lining (see Division H1).

Filed: 1973-11-23
Abstract: 1406968 Carbon; recovery from aqueous dispersions TEXACO DEVELOPMENT CORP 23 Nov 1973 [29 Dec 1972] 54560/73 Heading C1A Particulate carbon is recovered from a water dispersion by mixing the dispersion in a mixing zone with a first hydrocarbon oil having a density less than that of water in an amount just sufficient to render the carbon dry and fluffy, allowing the resulting mixture to settle in a settling zone to permit the carbon to rise to the surface of the water, adding a second hydrocarbon oil to form a hydrocarbon oil-carbon dispersion on the surface of the water, and separating the hydrocarbon oil-carbon dispersion from the water. The second hydrocarbon oil may be a petroleum residium, optionally mixed with naphtha. The first hydrocarbon oil may be a petroleum fraction boiling within the C 5 - naphtha range (optionally naphtha) and may be flashed from the hydrocarbon oil-carbon dispersion after its removal from the settling zone. The residue from the flashing process may be subjected to partial oxidation for the production of a gas composed principally of carbon monoxide and hydrogen. The C 5 -naphtha fraction from the flashing process may be recycled to the mixing zone. The amount of the first hydrocarbon oil used may be between I and 2 times the oil adsorption number of the carbon (1À5-10 lbs. of oil per lb. of carbon). The second hydrocarbon oil may be added in an amount sufficient to form a dispersion containing from 1 to 5% by weight of carbon. The watercarbon dispersion may contain between 0À5 and 4% by weight of carbon. The hydrocarbon oil-carbon dispersion may be separated at 180‹ to 475‹ F. The process may be used to recover carbon from aqueous dispersions formed in scrubbing synthesis gas with water.
