Inventor: LYMN ARTHUR HENRY
IPC: C01B21/30
Filed: 1913-02-07
Granted: 1914-02-09
Abstract: 3194. Lymn, A. H. Feb. 7. Nitrogen oxides and oxyacids. are prepared by causing nitrogen and oxygen to combine directly with each other by contact with a bed of a refractory substance or a porous mass. of refractory substance, which is heated by the burning of a combustible gas in contact with or within the mass of the refractory substance. A convenient apparatus consists of a tube filled with pieces of refractory substance such as fire-clay, of fragmentary or special shape, the combustion taking place inside and around the bed and the parts comprising the same; or the combustible gas may be passed into the interior of a cylinder or the like of porous refractory material through which the gas passes and is ignited at or near the surface thereof. The refractory material is brought to the requisite temperature by burning around or within it a mixture of combustible gas and air, after which the nitrogen and oxygen requisite for the formation of the nitrogen oxides &c. is passed in together with a suitable proportion of combustible gas, care being taken that the flames do not strike back or the gases do not explode before the proper time or place. The supply of combustible gas may be discontinued, if the refractory material has been sufficiently heated, until the material ceases to be hot enough to continue the process. - Steam superheated to the point of dissociation or hydrogen and oxygen in any other form may be added to the gases. The gases may be passed into the apparatus intermittently to produce a series of explosions, or the gases may be passed in at a high velocity. The process may be worked at a pressure above, at, or below atmospheric pressure. The nitrogen oxides formed are at once cooled in any suitable manner to prevent dissociation.

Title: A Process for the Preparation of Elements with the Assistance of Volatile Compounds of the same.
IPC: C22B60/02
Filed: 1914-03-09
Abstract: 5939. Ehrich & Graetz and Podszus, E. March 19, [Convention date]. Void. [Published under Section 91 of the Act.] Boron; silicon.-Boron and silicon are obtained by the reaction of highly-heated metal vapours upon compounds of these elements; preferably volatile compounds, such as chlorides, sulphides, or phosphides, of the elements are employed in a state of vapour, which is caused to flow against a stream of the metal vapour; the process can also be effected, however, by spraying the compounds in finely-divided form into the metal vapour, or blowing them in powder form by means of an indifferent gas. The metal vapour preferred is mercury vapour, or vapour of amalgams; vapours of copper, silver, sodium, potassium, calcium, &c., also are suitable. The metal vapour should preferably be present in the reaction zone in excess; the metal vapour may be employed pure, or mixed with gases, such as hydrogen. The source of the metal vapour is preferably an electric vapour arc. In this way. boron is obtained bv passage of the vapours of the chloride through a mercury vapour arc. The products of the reaction are rapidly cooled and can be separated bv distillation in vacuo or in an inert atmosphere. In the apparatus shown in Fig. 1, a tube 1 of quartz &c. is provided with a tungsten electrode 6 attached to an iron rod 5 passing through a plug 3 in the neck 2; a mercury seal 4 may be provided; the other electrode is formed by mercury in a U-tube 7, 8; the level of the mercury is regulated by means of an iron rod 9, or by attachment of the tube 8 to a movable receptacle containing mercury. The portion 7 is provided with a nozzle 11 which carries a tube 12, these parts serving to render the arc stable. The arc is struck by filling the tube 7 with mercury, bringing the electrode 6 into contact with this, then raising the electrode 6 and lowering the mercury level to the position shown. The compound to be treated, say boron chloride, is contained in a vessel 13 which can be suitably heated. The tube 1 is first preferably rinsed with hydrogen by means of an inlet 15 and outlet 16, the latter being provided with a mercury seal ; the hydrogen is then driven out by the vapours of the boron chloride, the outlet 16 being left open for this purpose. Several adjacent arcs may be employed. The produots can be separated by cutting out the are and maintaining the heat of the tube 1 within low limits, collecting means being fitted to the mouth 18. The electrode 6 may be of boron, titanium, etc.; it is desirable that it and the nozzle 11 should be of materials related to the element to be produced; for example, for the production of boron, the nozzle should be of boron nitride. In the construction shown in Fig. 2, the tube 7 fits removably in a nipple 19 on the tube 1 and is provided with a mercury seal 20; the pipe 8 is connected by a rubber tube 21 to a mercury container 22.

Granted: 1915-06-07
Abstract: 12,475. Gibbs & Co., Kestner Evaporator and Engineering Co., Hobsbawn, I. B., and Grigioni, J. L. May 20. Sodium chloride and nitrate solutions, concentrating; separate heater and evaporator apparatus.-Sodium nitrate, free from or containing a predetermined proportion of sodium chloride, is produced from liquors obtained from caliche and other crude materials, by a process of concentration involving two stages, namely (1) concentrating the liquor until its boiling- point reaches the critical temperature at which the sodium chloride becomes insoluble or a temperature lower than the critical temperature and dependent upon the desired percentage of sodium chloride; (2) transferring the hot desalted liquor to a second evaporator in which the nitrate of soda is separated as crystals. The critical temperature is ascertained by determining the maximum boiling- point of a sample of the liquor under normal atmospheric pressure (14À7 lbs. per square inch) and is usually about 123-124‹ C. The apparatus may consist of a multiple effect comprising first and second stage evaporators 1, 4, each composed of one or more calandrias 2 and a separator 3 fitted with a depending partition 14 and connected to the calandria by circulating-pipes. The liquor is pumped through a preheater 9 to the evaporator 1. The sodium chloride is transferred intermittently to a filter box 19 from which the mother-liquor flows by a pipe 22. Desalted liquor flows from the upper part of the separator 3 by a pipe 16 and together with liquor from the pipe 22 enters the second evaporator 4. The evaporator 1 is worked at a pressure of about 14À7 lbs. per square inch, and the evaporator 4, working at a lower pressure, is provided with a condenser 18 and air-pump 17, unless the plant is situated at an altitude above sea-level.
