(11.) The improved system of hydraulic air-compression which consists in establishing the downward and upward or return flow of a column of water, and separating the air contained therein from the upward or return portion of such column of water. (12.) An apparatus for compressing air by the action of a body of water travelling first downwardly and then upwardly, means for separating the air from the water under pressure during its upward travel. (13.)

(14.) An hydraulic air-compressing apparatus having a vertical standpipe for conducting the water downwardly; a dome located at and enclosing the lower end of said standpipe, and having a truncated conical top; a vertically arranged cylindrical section with open ends, supported in said dome above the lower end of said standpipe; a horizontal diaphragm dividing said cylindrical section midway of its height; a tubular section connected at its upper end to the edge of the opening in the top of the dome and extending downwardly a short distance below the upper edge of the cylindrical section, an air-pipe leading from a point a short distance above the lower end of said cylindrical section upwardly to the space between said tubular section and the top of the dome; and a second air-pipe leading from said space to the point of consumption, substantially as described and for the purpose set forth. (15.) In hydraulic air-compressing apparatus having a vertical standpipe contained within an enclosing chamber, and a vertical return passage for the water from said standpipe, with a lateral bend therein, and means for separating the air from such water during its upward flow and before it passes through such lateral bend.

No. 13063.—12th October, 1900.—ALEXANDRE TROPENAS, of 6, Rue d’Erlanger, Paris, France. Improvements in the manufacture of steel, steel-castings, or ingot-iron, and in apparatus and appliances employed therein.

Claims.—(1.) In the acid or basic processes by the pneumatic system, the improved method of manufacturing steel, steel-castings, or ingot-iron, by causing the blast of air to act only upon the surface of the molten bath, so as to avoid the agitation and gyrating motion peculiar to other pneumatic processes, substantially as described. (2.) The general construction and arrangement of apparatus as described for carrying out my improved method of manufacturing steel, steel-castings, or ingot-iron. (3.) The use in my improved apparatus of two or more rows of tuyères arranged and operating substantially as and for the purposes described. (4.) The method of increasing the temperature within the converter by projecting air through tuyères arranged at a sufficient height for causing combustion of the carbonic oxide and hydrogen evolved during the operation, substantially as described. (5.) In the acid or basic processes of the manufacture of steel, steel-castings, or ingot-iron by the pneumatic system, the particular disposition, arrangement, and combination of parts and appliances substantially as described, and as shown in Figs. 1, 2, 3, and 4 of the drawings.

(6.) In the acid or basic processes of the manufacture of steel ingots, steel-castings, and ingot-iron by the pneumatic system, constructing the converter-bottom conical, round, hemispherical, or of any other convenient shape, by means of which a great depth in proportion to the surface-area at the top and cubical capacity of the same is obtained, in the manner and for the purposes substantially as described and illustrated. (7.) In the acid or basic processes of the manufacture of steel ingots, steel-castings, and ingot-iron by the pneumatic system, the particular disposition, arrangement, and combination of parts and appliances comprising—the outlet provided near the upper portion or throat of the converter in addition to the ordinary orifice, the pipe leading from the said orifice whereby a portion of the gas emitted from the bath may be conducted through one of the trunnions, the receiver through which the gas passes from the last-named pipe and trunnions into a regenerator or regenerators in which the air used in the blowing process is heated on its way to the converter, in the manner and for the purposes substantially as described and illustrated. (8.) In the acid or basic processes of the manufacture of steel ingots, steel-castings, and ingot-iron by the pneumatic system, the use of the particular disposition, arrangement, and combination of parts and appliances comprised in claims 5 and 6, either with or without the apparatus and appliances described in claim 7—that is to say, I claim the use of my improved apparatus and appliances as described in claims 5 and 6, either with hot or with cold air, in the manner and for the purposes substantially as described and illustrated.
