Title: Boiling water nuclear reactor
IPC: G21D3/12
Filed: 1960-10-05
Abstract: 934,656. Cooling reactors. GENERAL NUCLEAR ENGINEERING CORPORATION. Oct. 5, 1960 [Oct. 9, 1959], No. 34196/60. Class 39 (4). A boiling water reactor has forced circulation through the central part of the core and convective circulation through the outer part of the core. Fig. 2 shows a reactor whose core has a central part 18 inside a baffle 14 and an outer part 20 inside a baffle 16 and covered by members 56 which can be lifted for refuelling. Water is pumped into the bottom of part 18, then flows down outside the core and up through part 20 by natural convection. Steam mixed with water flows to a separator 22, steam from which is added to steam from reactor outlet 34 and fed to a turbine. Turbine condensate returns to separator 22 and thence to the reactor. The natural circulation in the reactor is encouraged by lowering the separator relative to the water level in the reactor, by feeding some of the turbine condensate through line 49 to increase the density of the water flowing down outside the core, and by putting in the steam outlet 34 a throttle which is fixed or is adjustable according to the demand of the turbine. The fuel rods in part 20 may be more widely spaced than in part 18. The reactor is controlled by manual and automatic control rods, and by varying the proportion of condensate fed through line 49, thus varying the core temperature and average void fraction. Proportioning valve V-2 is set according to the turbine throttle position or to the error between turbine demand and reactor power; its range of control is altered by changing voltage Vref. Control rods automatically keep the reactor pressure constant; their movement also depends on the rate of change of steam flow. A by-pass valve V-5 and various level and flow controllers are provided.

Patent GB-636650-A (GB)
Title: Process for the saponification of organic sulphochlorides and purification of the saponification products
Filed: 1946-11-20
Abstract: Alkyl sulphochlorides such as decylic or dodecylic sulphochloride are saponified and the products are purified, by a process in which alkyl sulphochlorides are heated with a solution of an alkali metal carbonate at a temperature above 100 DEG  C. under pressure with simultaneous introduction of steam and the unsaponifiable matter is distilled off into a vacuum vessel, the carbonic acid being allowed to escape simultaneously.  The invention is carried out by heating a solution of the alkali metal carbonate in an autoclave to a temperature above 100 DEG  C., introducing the alkyl sulphochloride by means of a pump.  Steam is then introduced, causing carbonic acid to be driven off and the unsaponifiable constituents are distilled into a vacuum vessel. The alkali metal chloride may be separated from the product by so adjusting the concentration that on cooling the contents of the autoclave the alkali metal chloride separates and may be removed by filtration or centrifuging.  In an example an alkyl sulphochloride is saponified with ammonia soda by the above process giving an alkyl sulphonate solution.
Patent GB-797946-A (GB)
Title: Colouring cellulosic textiles
Inventor: ALSBERG FREDERICK RICHARD
IPC: D06P/
Filed: 1954-11-29
Abstract: Cellulosic textile materials are coloured by impregnating them, locally or otherwise, with an aqueous medium containing a monoazo or polyazo dyestuff having at least one ionic solubilizing group, such as a sulphonic acid or carboxylic acid group, and also at least one primary or secondary amino group carrying as N-substituent a 1 : 3 : 5 triazine radical containing at least one halogen atom attached to a carbon atom of the triazine ring, and then subjecting the materials to the action of an acid-binding agent in aqueous medium. Alternatively, the textile may be treated, before, during or after the application of the dyestuff, with an aqueous solution of a substance which on heating or steaming liberates an acid-binding agent, in which case heating or steaming is finally applied.  As applied to printing, the acid-binding agent or a substance which, on heating or steaming, liberates an acid-binding agent, may be incorporated with the dyestuff in the printing paste, and the printed material may then be heated or steamed.  Suitable acid-binding agents are caustic soda, caustic potash, sodium carbonate or bicarbonate, trisodium phosphate and sodium metasilicate, suitable substances liberating the acid-binding agent on steaming being sodium bicarbonate and sodium trichloroacetate.  Electrolytes, such as sodium chloride or sulphate, may be added to the aqueous solution of the acid-binding agent.  The dyebath or printing paste may contain the usual additives such as urea, sodium sulphate, sodium alginate, cellulose ethers, starch and locust bean gum.  The material may be padded with the dyestuff solution and dried prior to treatment with the acid-binding agent.  In continuous processes, e.g. employing the molten-metal technique, the drying step may be effected at 70-170 DEG C.  If the dyestuffs contain metallisable groups, then an after-treatment with a metal compound, e.g. a copper, nickel, cobalt or chromium compound, may be effected. Examples of dyeing and printing are given.  The dyestuffs may be prepared by condensing an amino-azo or amino-polyazo compound with cyanuric chloride or by coupling a diazo compound with a primary condensation product from an amino compound and cyanuric chloride or by condensing a diamine and cyanuric chloride, diazotizing the so-formed product and then coupling with an appropriate component. Long lists of suitable dyestuffs are given.  Specifications 342,167, 363,897, [both in Group IV], 774,925, 785,120 and 785,222 are referred to.
