Title: Improvements in the Obtainment of Cyanogen Compounds.
Inventor: MACTEAR JAMES
Filed: 1899-03-07
Granted: 1900-01-13
Abstract: 5037. Mactear, J. March 7. Ammonium, potassium, sodium, and iron salts.- Ammonium cyanide is produced by heating a mixture of two molecular proportions of ammonia with one molecular proportion of carbon monoxide, preferably in presence of a catalytic agent such as charcoal, to a temperature of 1800‹ to 2000‹ F. by means of electrical resistances. Producer or Dowson gas may be used instead of carbon monoxide. The mixture of gases is passed through the branches b<2> of a main b<3> to holes b<1> in the cover b of an oblong chamber a, the top flange a<1> of which contains a channel a<2> communicating with the holes b<4> and with holes a<3> leading into the chamber. The mixture passes through the charcoal g, and is heated uniformly by electrical resistances h, which are equidistant from each other and from the walls of the chamber, and consist of coils of platinum wire wound upon refractory material mounted in closed tubes j. The chamber may also be heated externally by electrical resistances wound round it, or by gaseous fuel. The gases pass through the perforated bottom, and out of the chamber through holes, channels, and branched mains similar to those by which they entered. The top and bottom covers of the chamber are luted thereon by a suitable cement at d, and are bound thereto by metal bands. The gases, after leaving the chamber, are cooled and conducted to a chamber containing caustic soda or potash for the production of sodium or potassium cyanide, and the ammonia which is evolved in these reactions is collected for re-use in the cycle of operations. The solutions of alkaline cyanides thus obtained are evaporated, preferably in vacuo. Ferrocyanides are obtained from the ammonium cyanide by the known processes.

Title: Improvements in and in connection with the Desulphurisation of Sulphuretted Hydrogen.
Inventor: HEMINGWAY HENRY WILLIAM
Filed: 1899-05-04
Granted: 1900-03-17
Abstract: 9432. Hemingway, H. W. May 4. Sulphur.-Relates to the treatment of sulphuretted hydrogen, or gases containing sulphuretted hydrogen, to obtain sulphur, and incidentally other products, such as iron sulphite and ammonium sulphate. The gases are brought by a tube A, and a portion of the gases is burned in the furnace B to form sulphurous acid. This acid is passed by a tube b to a reaction tower C packed with coke, flints, &c., which also receives a stream of ammoniacal gas or ammonia, (from any source), by the tube D, and down which water is sprinkled from the tube E. A solution of ammonium sulphite runs away by the tube c to the tank F, where it is mixed with a solution of ferrous sulphate from the tank G, resulting in the formation of a mixture of ammonium sulphate and fe-rous sulphite. This mixture is forced by the pump J to the tank K, and is distributed by the rockins contrivance l to the top of the packed tower L. The unabsorbed sulphurous acid from the tower C passes by the tube c<1> to the tower H, where it meets with the remainder of the sulphuretted gases, entering through the tube A. Pentathionic acid is formed, and the solution runs away to the tank M, where it is immediately decomposed by scrap iron, iron sulphide being deposited, while sulphuretted hydrogen is liberated, and passes by the pipe h' back to the tower H. By the use of the tower H the whole of the sulphurous acid is utilized. The sulphurettedhydrogen gases then pass hy the tube h to the column L. The result of the reaction within this tower is a solution of ammonium sulphate, which runs away to the vessel l<4>, and sulphur and iron sulphide, which are deposited as solids upon the packing in the tower. Sulphurous acid from other sources may be used in the process. The ferrous sulphite may be separated from the ammonium sulphate by subsidence &c. and be used along with water in the tower L. A solution of soda ash may be used instead of ammonia, whereby sodium sulphite is first obtained, and afterwards sodium sulphate. Instead of iron sulphate, copper or zinc sulphate may be used, or even metallic chlorides.

Patent GB-190100757-A (GB)
Title: An Improved Station Indicator.
Inventor: LUSTIG ARNOLD
Filed: 1901-01-11
Granted: 1901-05-04
Abstract: 757. Lustig, A., and Meth, E. Jan. 11. Indicators, station. -Relates to station indicators for railway trains. The names of the stations are marked in succession on the series of dials a', a', a<3>, &c., each of which is formed with a gap corresponding to a sight aperture in the casing. When the outer dial a<1> has completed a revolution, it is stopped with its gap corresponding to the sight aperture, while the subsequent operation of the apparatus effects the rotation of the second dial a<2>, to exhibit the names on it through the sight aperture and the gap in the dial a'. Similarly, the second dial is stopped at the end of its revolution, and the third dial brought into use. The movement of the dials is effected by the double arm f, which is rotated in one direction by the pawl and ratchet-wheel d, e, actuated by the electromagnet c, and in the reverse direction by the pawl and ratchet-wheel o, p, actuated by the electromagnet n. The arm f carries a pin g, which is guided by the groove h, Fig. 5, and is adapted to engage with a notch in the edge of each dial. When the dial engaged by the pin has completed its revolution, the pin is shifted by the inclined part i of the groove h into the notch of the next dial, the first-mentioned dial being then held stationary by a spring engaging a flat on the fixed spindle k<1>. The indicator may be mounted in the partition of a carriage, so as to be visible in two adjacent compartments. A bell may also be rung at each movement of the indicator. The electromagnets c of the indicators in the various compartments are connected in series with the leads b<1>, c<1> of the controlling-apparatus, Fig. 7, in the guard's van, the magnets n being similarly connected to the leads d<1>, e<1>. The operating-lever k is provided with two contact-makers t, u, which are mounted, under the control of springs q<1>, q<2>, as shown in Fig. 8, and are respectively connected to springs which rub on the conducting-rings s, r. When the lever k is moved in clockwise direction over the dial, the contact-maker t enters the notches v in the insulating-ring l, and rides over the contacts x, which are all connected together and to the lead b<1>, so completing the circuit b<1>, x, t, s, c' of the electromagnets c each time a contact x is passed over. During this movement, the contact-maker u is held, as shown in Fig. 9, out of engagement with the contacts y in the insulating-ring m. When the movement of the lever k is reversed, the contact-maker u enters the slots w of the ring m, and rides over the contacts y, so completing the circuit d', y, u, r, e' of the electromagnets n, while the contact-maker t is deflected to the outside of the ring l. When it is desired to effect the adjustment of the various indicators, as in the case of a train picking up extra carriages at an intermediate station, the lever k is moved round in clockwise direction to its extreme limit, then in the reverse direction back to the starting point, and, finally, up to the name of the intermediate station.

The plunger B is formed with a doublethreaded screw B<2> of very coarse pitch, which engages a nut C passing through the door and supported at the outside by a plate E and at the inside by a box F. The box is closed by a coverplate K having a central boss to support the plunger. At the inner end the nut C is provided with a disc C', to which are pivoted the ends of links G connected at the opposite ends to sliding bolts H for securing the door. Normally these bolts are shot, but, on the plunger B being forced in by a push on the pressure bar, the disc C' is rotated and the bolts are withdrawn, freeing the door. A pivoted arm S is adapted to engage a slot T, when the plunger is forced inwards, so as to lock the pressure bar to the plate K and secure the bolts H in the withdrawn position. A square hole C<3> in the end of the nut is adapted to receive a key for operating the fastening from the outside. This form of fastening is suitable for each of two double doors. Where only one bolt is employed, only one link is used, or the construction may be modified, the links G being replaced by a tooth on the nut, which tooth engages a recess in the bolt. This modification may also be employed for withdrawing the double bolts of double doors, two teeth being provided, one to engage each bolt.
