Title: Improvements in Apparatus for Exhausting, Propelling, or Inducing Currents in Air or other Fluids.
Inventor: JAMES CHRISTOPHER WILLIAM
Filed: 1894-12-20
Granted: 1895-11-02
Abstract: 24,751. James, C. W., and Watson, G. Dec. 20. Blast apparatus and draught-inducers.-Steam or other inducing-jets of flat or rectangular crosssection are employed. The size of the jets can be varied by making one or more sides of the nozzles adjustable. Figs. 3 and 5 show a nozzle of which one side only is adjustable. It consists of a tube E drawn down to the required form, the sides being then cut away from F to the end, and the end secured in a sleeve G. The side D can be moved towards and away from the opposite side of the nozzle by turning the nut L in one direction or the other. The side D may be adjusted by other means, as by a wedge, and the nozzle may be of cast metal, in place of being formed from a drawn tube. Figs. 12 and 13 show, respectively, transverse and longitudinal sections of a nozzle in which two sides are adjustable. two rods or spindles A, D are mounted in contact with one another, near the end of the nozzle. In the rods are cut flats I, H, so that, by rotating these rods to bring the flats towards one another, the width of the orifice is varied. Fig. 21 shows a longitudinal section of a nozzle in which all four sides of the orifice are movable. The nozzle consists of a split tube E with tapered screwed ends on which are nuts. By screwing the nuts on the tube, the length of the slot can be reduced, and at the same time the width is reduced, and vice versÔ. In a modification of this form, a longitudinal slot is cut in a tube, and the effective length of the slot is varied by screwing nuts towards or away from ore another along the tube. In a further modification, several slots, similarly adjusted by nuts, may be cut in a tube to form a multiple. jet apparatus. Such rectangular jets are blown into tubes of similar section, which may be tapered in both directions, or in one direction only, or they may be projected into a series of such tubes, one behind the other. When such an apparatus is employed as a draught-inducer for two-furnace boilers, the tube into which the jet is blown is bifurcated with a branch leading to each furnace, and has a valve by which the amount of air supplied to each furnace can be adjusted.

Abstract: 29,631. Imray, J., [Soc. Anon. des MatiÞres Colorantes et Produits Chimiques de St. Denis]. Dec. 14. m-Chloro-, m-sulpho-, and m-hydroxy-o-sulphobenzaldehydes are produced from the solution of o-sulpho-m-amidobenzaldehyde obtained as described in Specification No. 18,002, A.D. 1897, by first removing the excess of sodium sulphite by addition of calcium chloride, then diazotizing the amido compound, and finally decomposing the diazo product. The chloro derivative is obtained by the action of hydrochloric acid and copper on the solution of the diazo compound ; the oxy derivative by boiling the solution of the diazo compound upon a water bath ; and the sulpho derivative is produced, without previous elimination of the excess of sodium sulphite, by saturating the solution of the diazo compound with sulphurousacid gas and adding copper powder. Dyes, artificial, of the triphenylmethane series are produced by condensing the foregoing mchloro-, m-oxy-, and m-sulpho-benzaldehyde-o-sulphonic acids with secondary or tertiary aromatic amines, or their sulphonic acids, and then oxidizing the leuco products thus obtained. The dyes are also produced by transforming the leuco compounds or dyes obtained as described in Specification No. 18,002, A.D. 1897, into chloro, sulpho, or oxy derivatives as described above. Azo compounds are also produced of the form B-N = N-R, in which B represents the aldehyde compound, and R a phenol or amine.
