IPC: F22D1/32
Filed: 1930-11-18
Abstract: 351,077. Heating feedwater. MURISON, J. S., 96, Taff Embankment, Cardiff. Nov. 18, 1930, No. 5467. [Class 64 (i).] Feedwater is heated partly by reheated exhaust steam from main engines and partly by reheated exhaust steam from auxiliary engines. Exhaust from main and auxiliary engines 17, 23 is passed through reheaters in the path of gases from the boiler furnaces and then through tubulous feedwater heaters 12 . . 16 arranged between the feed pump 10 and the boilers 36. The main engine exhaust passes through the first two feed heaters 12, 13 and is then led into the condenser 21. At starting, a valve 40 in the exhaust pipe 18 is opened to allow the exhaust to flow directly into the condenser, a stop valve 40a in the pipe being closed.

Title: Improvements in and relating to catalysts
IPC: B01J25/02
Filed: 1947-02-26
Abstract: Nickel-silicon foraminate catalysts are prepared by treating an alloy, in which the ratio by weight of nickel: silicon is from 30 : 70 to 85 : 15, with aqueous alkali to remove not more than 70 per cent of the original silicon content.  The alloy is prepared from a melt by rapid cooling and broken up into granular grading between 1/16 to 1 inch.  An aqueous solution of 5 to 50 per cent by weight caustic soda is used at approximately 100 DEG  C.  The alkali, if not washed out of the catalyst, may be used as a promoter therefore. Regeneration is effected by oxidation and reduction, but below 400 DEG  C.  The catalysts may be used for hydrogenation, dehydrogenation, hydrogenolysis and reductive amination, particularly ethylene to ethane, dihydropyran to tetrahydropyran, and cyclohexane to benzene.ALSO:Nickel-silicon feraminate catalysts are prepared by treating alloys in which the ratio by weight of nickel-silicon is from 30 : 70 to 85 : 15, with aqueous alkali to remove not more than 70 per cent of the original silicon content.

Filed: 1944-03-28
Abstract: 580,378. Wave guides. FENWICK, C. E., and WRIGHT, C. S. March 28, 1944, No. 5741. [Class 40 (v)] [Also in Group XXXVI] Wave guides having uniform inner surfaces of good electrical conductivity are made by coating the external surface of a former of the desired shape with metal foil, and subsequently electro-depositing a layer of metal over the outer surface of the metal foil until a desired degree of mechanical strength of the metal part is obtained. The metal foil is preferably gold leaf which is fixed by an adhesive to the former which may be of synthetic resin such as polythene or polystyrene. Alternatively, where an air dielectric is required, the former may be of wax or other low melting-point material which is melted out after the wave guide has been formed. Alternatively, it may be dissolved out. The electro-deposited metal may be copper or may be a plurality of metals.

Abstract: 372,004. Automatic exchange systems ; variable resistances. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, London, and GRINSTED, W. H., Under the Plane, London Lane, Bromley, Kent. Feb. 25, 1931, No. 5895. Drawings to Specification. [Class 40 (iv).] To enable the voltage necessary for transmission over long lines to be used without the danger of overheating on short lines, the resistance of a feed impedance, e.g. a, line or back-bridge relay, is reduced, the impedance to speech currents being maintained by using special iron for the core or by providing the core with a sheath of such iron as described in Specification 254,364, [Class 37, Electricity, Measuring &c.], and there is arranged in series with it a ballast resistance such as an iron, nickel, or tungsten wire in an evacuated vessel or one containing inert gas, to keep the current in the talking circuit between predetermined limits. The ballast resistance may be in two parts contained in the same envelope and connected respectively to the two windings of the impedance. In the case where the ballast resistance is connected to one winding only the other is coupled to a third, short-circuited winding to avoid unbalance of the two legs of the line. Alternatively the resistance may be shunted by a condenser.
