Title: Improvements in or relating to the control of forced-flow once-through boilers
IPC: F22B35/10
Filed: 1960-12-22
Abstract: 924,519. Forced-flow steam boilers. PRVNI BRNENSKA STROJIRNA, ZAVODY KLEMENTA GOTTWALDA, NARODNI PODNIK. Dec. 22, 1960 [Dec. 23, 1959], No. 44133/60. Class 123 (2). In a forced-flow, once-through boiler comprising a feedwater regulator 1, a preheater 2, an evaporator 3, a separator 4 and superheater sections 5, 6, 7 of which the section 6 is a large, convectively-heated superheater and wherein the separated water from the separator flows through a line 8 to be infected at a point 9 at the inlet of the superheater section 6, the ability of the boiler to cater for sudden variations in load is improved by providing for an increased flow of water in the line 8 when the load rises and vice versa. A line 10 controlled by a valve 11 leads from the boiler inlet to the line 8, the valve 11 being controlled by a regulator 15 which receives signals representative of feedwater flow and separated water flow taken at points 12, 13 respectively and actuates the valve in response to these signals to maintain steady steam-water conditions at the evaporator outlet. The regulator also receives a signal representative of load from a sensing device 14 in response to which it opens the valve when the steam demand increases and vice versa. On a sudden increase in load the additional water injected at 9 is evaporated in the superheater 6 which has a large reserve of stored heat which also serves partly to compensate for the fall in temperature of the steam, the final temperature being brought to the desired value by adjusting the rate of injection of attemperating water between the superheaters 6, 7. Subsequently, as the firing rate and feed supply rate increase to meet the new demand the valve 11 is moved towards its closed position by the regulator. The converse action occurs when the steam demand suddenly falls.

Filed: 1963-11-12
Abstract: 1,092,107. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 2, 1964 [Nov. 12, 1963; Jan. 14, 1964], Nos. 44591/63 and 1714/64. Heading G6C. A reactor having a core through which pressurized liquid coolant-moderator is circulated includes a pressurizer and a flow guide to isolate a stream of coolant in the core for delivery to the pressurizer, so that in operation the pressurizing stream is hotter than the remaining coolant in the core. The reactor has a core 11 comprising a plurality of fuel assemblies mounted between grid plates 12, 13. The pressurizer 35 is situated above the core and is fed with the isolated stream of hotter pressurized water, derived from the centre fuel assembly, through an orifice 38e and pipe 38. The pipe end 38c is closed and the pressurizer water is delivered to the pressurizer through spray nozzles in the pipe upper side walls. The coolant is circulated by pumps 21 through inner coaxial duct 23 to an inlet plenum chamber, through the core fuel assemblies to a space 26 (and pipe 38), upwards within a cylindrical containment 25 to the upper end of the heat exchangers 27, through the heat exchangers, to an annular chamber 18, and finally to the pump inlet. Pressurizer water is fed to the main coolant stream through inverted U tubes 39 which extend downwards through the heat exchangers to discharge at a point just above the mainstream core outlets. In a modification, the inverted U tubes are dispensed with, and instead the bottom of the pressurizer tank is left open. Containment and insulation,-The pressurizer tank 35, pipe 38 and pressure vessel 17 are all provided with heat insulation skins. A gas layer is maintained between the pressure vessel 17 and a shroud 41. Vessel 42 is filled with water, to a level 45, which is cooled by heat exchanger pipes 46. If the pressure vessel burst, water passes from it to the shroud 42, which contains a rupture disc 48 which allows contaminated pressurized reactor water to be absorbed below the surface of the water in the shell 42. Modifications.-The pressurizer fuel assembly may be in a core position of depressed neutron flux, thus enabling the pressurizer stream to attain a higher temperature without fuel burnout. Variable flow restrictors may be incorporated in the pressurizer circuit to adjust the over-pressure. The pressurizer stream may be derived from a fraction of normal coolant flow being returned from the core outlet to a second pass through an isolated part of the core.

Abstract: 1,127,177. Paper. AMERICAN CYANAMID CO. 25 Oct., 1965, No. 45136/65. Headings D2A and D2B. Paper of improved dry tensile strength but low wet strength is substantially composed of water-laid fibres of unbleached cellulose, bonded together by an ionically adsorbed content of a normally water-soluble, two-dimensional, non-thermosetting cationic polyamine containing at least five amino nitrogen atoms per macromolecule, and having a molecular weight between 1,000 and 10,000. The fibres may contain more than 1 % of acidic lignin material, and the polyamine may be used in amount sufficient to neutralize substantially all of this material. The polyamine may be formed by reacting substantially completely, to a point short of gelation, epichlorohydrin with a major proportion of water-soluble "bifunctional" amine and a minor proportion of water-soluble "polyfunctional" amine, the ratio of the "functionality" of the epichlorohydrin to the total "functionality" of the amines being substantially 1:1. "Bifunctional" and "polyfunctional" are defined as meaning capable of reacting twice or more than twice, respectively, with epichlorohydrin; and "functionality" as number of reactive functions present. In the Examples: (A) 1.2 mol of aqueous methylamine, 0.2 mol of ethylendiamine, and 1.6 mol of epichlorohydrin are reacted in a flask in the presence of water and of sodium hydroxide in the later stages, the solution is then neutralized with acetic acid and cooled: (B) 1 mol of methylamine, 0.2 mol of ammonia and' 1.3 mol of epichlorohydrin are reacted similarly, the final neutralization being with HC1: (C) 1.25 mol of tetraethylenpentamine is heated with 1.25 mol of adipic acid. and the product dissolved in water. 0.275 mol of epichlorohydrin is added. and after reaction the solution is acidified with HCl: (D) as C, but using methylenebisacrylamide in place of epichlorohydrin; (E) as C. but using 1.2-dichlorethane in place of epichlorohydrin; (F) one mol of tetraethylenpentamine is reacted with 1.2 mol of dichlorethane in the presence of water, and 1.2 mol of NaOH added to neutralize the acid formed. Papers are made by adding these polymers to unbleached pulp, sheeting out and drying. Fillers may also be present, e.g. ultramarine, clay, TiO., and calcium carbonate, or basic dyes. Any broke arising is readily repulped.

Abstract: 1277394 Glycol phosphatides A NATTERMANN & CIE GmbH 25 Sept 1970 [30 Sept 1969] 45747/70 Heading C2P The invention comprises glycol phosphatides of the general formula wherein R<SP>1</SP> and R<SP>2</SP> are acyl radicals of C 10 -C 24  fatty acids (preferably containing at least one unsaturated bond) and X is H or COOH. They may be obtained by dissolving phosphatidyl colamine and/or phosphatidyl serine in an organic solvent, adding aqueous nitric acid to effect diazotization and hydrolysis and then isolating the deaminated phosphatides. The nitrous acid is preferably formed by using an aqueous solution of a salt of nitrous acid and an acid salt of an organic or inorganic acid, e.g. sodium dihydrogen phosphate, sodium hydrogen citrate or potassium hydrogen phthalate. The process is generally effected with exclusion of air, e.g. in a nitrogen atmosphere, until the presence of the free amino group is no longer detectable by a ninhydrin test. Suitable solvents for the reaction are alcohols, chlorinated hydrocarbons containing 1 to 4 carbon atoms and hydrocarbons, or mixtures thereof. Pure cephalin or phosphatide mixtures containing cephalin may be used as starting material and these may for example be derived from various soybean phosphatide fractions or from raw egg phosphatide. If desired less than the amount of sodium nitrite and acid salts needed for complete de-amination of the cephalin may be used to give products in which some amino nitrogen is still present. The products have improved water-solubility and improved emulsifying properties for oil in water emulsions and are suitable for intravenous fat feeding.
