No. 16242.—15th April, 1903.—ARTHUR ROSS, of St. Clements, Carshalton Road, Sutton, Surrey, England, Gentleman (assignee of Samuel James Wilford, of 72, Worship Street, London, England, Engineer). Improvements in devices for circulating the water of boilers and the like and removing impurities therefrom.

Claims.—(1.) The combination with a steam generator or heater or other vessel, of a circulator such as that described which can be charged from outside the apparatus and which will then induce circulation as soon as the contents of the boiler or other vessel are heated, for the purpose specified. (2.) A circulator comprising a reservoir fitted with upflow and return pipes connecting the reservoir with the boiler or other vessel, and having for opening and closing the said upflow and return pipes automatically operating valves placed in proximity to the points at which said pipes join the boiler or other vessel, substantially as and for the purpose set forth. (3.) A circulating and purifying apparatus such as that described, having a charging-orifice with means for opening and closing the same and fitted with a bottom blow-off pipe, substantially as set forth. (4.) The combination of the top blow-off pipe I and the reservoir D, with or without the charging-orifice, substantially as and for the purposes specified. (5.) The circulator and purifier provided with an air-outlet at the upper part of the reservoir and with means for opening and closing said outlet, substantially as set forth. (6.) The combination with the circulator and purifier of a buoyant funnel constructed and hinged to the upflow-pipe, substantially as set forth, for the purpose specified. (7.) The apparatus constructed substantially as described with reference to the drawings, and operating as and for the purposes specified.

No. 16259.—22nd April, 1903.—THOMAS TERRELL, of 1, New Court, Temple, London, E.C., England¹, King’s Counsel. Improvements in the manufacture of incandescent mantles.

Claims.—(1.) In the manufacture of incandescent mantles by impregnating natural cellulose with salts of the illuminating metals, thoroughly drying the fibres after soaking in a solution of the salts, then immersing them in a strong solution of ammonia or other suitable alkali, substantially as and for the purpose described. (2.) The process of impregnating fibres of natural cellulose for incandescent mantles which consists in soaking the fibres in a concentrated solution of salts of the illuminating metals, thoroughly drying the fibres, immersing them in a concentrated solution of ammonia, and washing out the ammonia salts, the steps being repeated if necessary. (3.) The process of impregnating fibres of natural cellulose for incandescent mantles which consists in mer-cerising the fibres, soaking them in a concentrated solution of salts of the illuminating metals, thoroughly drying the fibres, and immersing them in a concentrated solution of ammonia, for the purpose described. (4.) The process of impregnating fibres of natural cellulose for incandescent mantles which consists in soaking the fibres in a concentrated solution of salts of the illuminating metals under a vacuum, thoroughly drying the fibres, and immersing them in a concentrated solution of ammonia, for the purpose described. (5.) The process of impregnating fibres of natural cellulose for incandescent mantles which consists in soaking the fibres in a concentrated solution of salts of the illuminating metals until they have absorbed from 30 per cent. to 48 per cent. of illuminating oxides, thoroughly drying the fibres, and immersing them in a concentrated solution of ammonia, for the purpose described. (6.) The process of manufacturing incandescent mantles which consists in soaking the fibres of natural cellulose in a concentrated solution of salts of the illuminating metals, thoroughly drying the fibres, immersing them in a concentrated solution of ammonia, washing out the ammonia salts, drying the fibres, and forming them into mantles, substantially as described. (7.) An incandescent mantle made by the described process. (8.) The complete process of manufacturing incandescent mantles, substantially as described.
